Depression

• Can refer to either:– A mood: a pervasive

and sustained emotional response

– A clinical syndrome: a combination of emotional, cognitive and behavioral symptoms

Page 4: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

How To Distinguish Depression From Normal

Sadness• The mood change is pervasive across situations and

persistent over time• The mood change may occur in the absence of any

precipitating events• The depressed mood is accompanied by impaired

ability to function in usual social and occupational roles

• The change in mood is accompanied by a cluster of additional signs and symptoms

• The nature or quality of the mood change may be different from that associated with normal sadness

Page 5: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Four Types of Symptoms Associated With Mood

Disorders• Emotional

• Cognitive

• Somatic

• Behavioral

Page 6: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Emotional Symptoms

• Depressed or dysphoric mood is the most common and obvious symptom of depression

• People who are depressed describe themselves as feeling utterly gloomy, dejected and despondent

• Manic patients experience euphoric like symptoms

Page 7: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Symptoms

• Involve changes in the way people think about themselves and their surroundings

• Depressed people may have trouble concentrating and are easily distracted

• Preoccupation with guilt and worthlessness

• Manic patients report sped up thoughts and ideas

Page 8: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Somatic Symptoms

• Related to basic physiological or bodily functions

• Include fatigue, aches and pains, and serious changes in appetite or sleeping patterns

Page 9: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Behavioral Symptoms

• Changes in the things that people do and the rate at which they do them

• Psychomotor retardation often accompanies the onset of depression

• Manic patients show energetic, provocative and flirtatious behavior

Page 10: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Diagnosing Mood Disorders

• Defined in terms of episodes– discrete periods of

time in which the person’s behavior is dominated by either a depressed or manic mood

Page 11: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive Episode

• Five or more of the following symptoms must have been present during the same two week period and represent a change from previous functioning

• At least one of the symptoms is either– Depressed mood– Loss of interest or pleasure

Page 12: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive Episode Symptoms

• Depressed mood most of the day, nearly every day

• Diminished pleasure in all, or almost all activities

• Significant weight loss (without dieting) or weight gain

• Insomnia or hypersomnia nearly every day

• Psychomotor agitation or retardation

• Fatigue or loss of energy

• Feelings of worthlessness or guilt

• Diminished ability to think or concentrate

• Recurrent thoughts of death or suicidal ideation

Page 13: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Manic Episode

• A distinct period of abnormally and persistently elevated, or expansive mood, lasting at least one week

• During the period of mood disturbance, three of more of the following symptoms have persisted and have been present to a significant degree

Page 14: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Manic Episode Symptoms

• Inflated self esteem or grandiosity

• Decreased need for sleep

• More talkative than usual

• Flight of ideas

• Distractibility (drawn to unimportant stimuli)

• Increase in goal directed activity

• Excessive involvement in pleasurable activities that have a high potential for painful consequences

Page 15: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Mood Disorders

• Two primary types:– Unipolar mood disorder: the person

experiences only episodes of depression– Bipolar mood disorder: the person

experiences episodes of mania as well as depression

Page 16: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Types of Mood Disorders and Frequency

Page 17: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Types of Mood Disorders

• Unipolar Mood Disorders– Major Depressive

Disorder– Dysthymic Disorder

• Bipolar Mood Disorders– Bipolar I Disorder– Bipolar II Disorder– Cyclothymic Disorder

• Subtypes

Page 18: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive Disorder• One or more major

depressive episodes• No manic or unequivocal

hypomanic episodes• Lifetime prevalence of

15%• Major Depressive

Disorder 15% suicide mortality

• VA 1991 Study– Major Depressive Disorder

mortality 38.7%– 13% no psychiatric

monitoring

Page 19: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive Disorder• Course is variable

– Some having episodes years apart, clusters of episodes, and some with frequent episodes throughout life

– Only about 20% have chronic episodes

• After the first episode, 50%- 60% chance of a second , and a 5%-10% chance of a manic episode (i.e. developing bipolar I disorder)

• After second episode, 70% chance of a third • After third episode, 90% chance of a fourth• The greater number of previous episodes is an

important risk factor for recurrence

Page 20: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive Disorder

• By definition, Major Depressive Disorder cannot be due to:– Physical illness, alcohol, medication, or street

drug use. – Normal bereavement. – Bipolar Disorder – 7Mood-incongruent psychosis (e.g.,

Schizoaffective Disorder, Schizophrenia, Delusional Disorder, or Psychotic Disorder Not Otherwise Specified).

Page 21: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Major Depressive DisorderCo-occurring Disorders

• Substance Abuse• Anxiety

– 80 to 90% of individuals with Major Depressive Disorder also have anxiety symptoms (e.g., anxiety, obsessive preoccupations, panic attacks, phobias, and excessive health concerns).

• Cancer, COPD (Chronic Obstructive Pulmonary Disease), Pain, eating disorders

• Causation:– Meds: steroids– Diseases: hypothyroidism

Page 22: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Dysthymic Disorder

• Depressed mood for at least two years

• Never without at least two of the following symptoms for more than two months– Poor appetite or overeating, insomnia or

hypersomnia, low energy, low self esteem, poor concentration, feelings of hopelessness

Page 23: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Dysthymic Disorder

• No major depressive episode during the first two years

• Lifetime risk of 3%

Page 24: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar I Disorder

• One or more manic episodes

• Lifetime risk of 1%

Page 25: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

These positron emission tomography scans of the brain of a person with bipolar disorder show the individual shifting from depression, top row, to mania, middle row, and back to depression, bottom row, over the course of 10 days.

Page 26: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar II Disorder

• One or more major depressive episodes

• At least one hypomanic episode– A hypomanic episode is a less severe version of

a manic episode.

• No manic episodes

Page 27: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Subtypes of Mood Disorders

• Melancholia: describes a particularly severe type of depression

• Psychotic features: when hallucinations or delusions were present during the most recent episode

• Rapid cycling: the person experiences at least 4 episodes within a 12 month period

Page 28: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Subtypes of Mood Disorders

• Postpartum Onset: when episodes begin within 4 weeks after childbirth

• Seasonal affective disorder: when the onset of episodes is regularly associated with changes in seasons

Page 29: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Prevalence of Mood Disorders

• Depression accounts for more than 10 percent of all disabilities in the US

• Younger generations are experiencing higher rates of depression, and those who become depressed are doing so at an earlier age

• Depression affects 13-14 million people each year

Page 30: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Prevalence of Mood Disorders

• Ratio of unipolar to bipolar is at least 5:1

• Lifetime prevalence of all mood disorders is 8%, ranked third behind substance abuse disorders and anxiety disorders

Page 31: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Gender Differences

• Women are two or three times more vulnerable to depression than men– Sex hormones, stressful life events,

childhood adversity, etc– May be more likely to seek treatment– May be more likely to be labeled as

depressed

• No differences seen in bipolar disorders

Page 32: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Children Statistics

• Up to 2.5% of children in the US suffer from depression

• Up to 8.3% of adolescents in the US suffer from depression

• Girls entering puberty are twice as likely to experience depression as boys

Page 33: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler
Page 34: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Types of Causes

• Environmental Factors

• Psychological Factors

• Biological Factors

Page 35: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Environmental Factors:Stress

– Levels of stress may vary from person to person.

– Depressive episodes can make a person more vulnerable to further episodes, so small amounts of stress can activate depression

• “Learner Helplessness”- after experiencing chronic or repeated stressful events, people can learn to feel helpless

Page 36: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Environmental Factors: Substance Abuse

– Depression that is a result of drug abuse, medication, or toxin exposure

– Associated with use and withdrawl from: alcohol, amphetamine, cocaine, hallucinogens, inhalants, opioids, phencyclidine, sedaitves, hypnotics and anxiolytics

– Exposure or habitual use of chemicals can alter brain structure and function resulting in depression

Page 37: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Environmental Factors:Childhood Difficulties

– Depression can develop in children who have experienced a traumatic event including but not limited to:

• Death of family member or friend • Natural disaster• Divorce• Loss of parent’s job, home, etc...

– Many of these children are emotionally damaged or lack emotional development and often have difficulties adjusting

– Traumatic Event may affect the development of the Limibic System

Page 38: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Depression In Disease

• Estimated 1/3 people with chronic disease have depression.

• Alzheimer’s– Boston Study

• 14% had history of depression

• HIV– 1/3 estimated to have

depression

Page 39: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Continued…• The rate for depression occurring with medical

illness*:– Heart attack: 40-65%– Coronary artery disease (without heart attack): 18-20%– Parkinson's disease: 40%– Multiple sclerosis: 40%– Stroke: 10-27%– Cancer: 25%– Diabetes: 25%

*Reviewed by the doctors at The Cleveland Clinic Department of Psychiatry and Psychology.

Page 40: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Psychological Factors

• Cognitive Vulnerability– People responding differently to the same

negative experience involving loss, failure and disappointment

Page 43: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors

• Neurotransmitters and Neurons– The signal enters the neuron through the dendrite

and proceeds through the cell body to the axon where it is switched from a electric signal to a chemical one

– Theses chemical signals are called neurotransmitters

• Neurotransmitters can fit into many receptors, but receptor sites can only receive specific transmitters

• Upon release the transmitter is broken down by mono amine oxidase (MAO) or its taken back in by the neuron that released it, called “reuptake”

Page 44: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors

• Of the 30 or so known neurotransmitters, depression effects Serotonin, Norepinephrine, and Dopamine

• Depression has been linked to both low and elevated Norepinephrine concentrations.

Page 45: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors: Serotonin

• The permissive hypothesis of serotonin function postulates that the deficit in central serotonergic neurotransmission permits the expression of bipolar disorder but is not sufficient to cause it.– According to this theory,

both the manic and the depressive phases of bipolar illness are characterized by low central serotonin function but differ in high versus low norepinephrine activity.

Page 46: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors:Norepinephrine

• The catecholamine hypothesis of affective disorders proposes that some forms of depression are associated with a deficiency of catecholamine activity (particularly norepinephrine) at functionally important andrengeric receptor sites in the brain, whereas mania is associated with a relative excess.

Page 47: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors:Dopamine

• Evidence is substantial that enhanced dopamine activity may play a primary role in psychotic depression.

Page 48: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors: Hormones

– About one half of all depressed persons have a high level of the hormone cortisol in their blood

– A person with a depressive mood disorder may not have their hypothalamus regulating the cortisol production in the adrenal gland correctly

– Normal cortisol levels peak at 8:00a.m. and 4:00p.m. for non depressed person, while a person with depression may have the hormone released at a constant level

Page 49: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors: Genetics• There is a 1.5 to 3% greater chance for a

person to develop a depressive disorder if a parent or sibling has it as well– 50% of those with bipolar disorder have a parent

with history of clinical depression– 25% of children of a parent who is bipolar develop

a depressive disorder– 50-75% of children of two parents with bipolar

disorder develop a depressive disorder

Page 50: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Biological Factors: Twin Studies

• If one twin develops depression there is a 76% chance that the other twin will develop a disorder as well– When raised apart the percentage is 67%– Because this number is not closer to 100%, there

is indication that other factors are also responsible

• Fraternal twins have a 19% chance of developing a depressive disorder if the other develops one

Page 52: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Causes of Depression

• Depression has been linked to size/function in the temporal and frontal lobes and the cingulate gyrus. However, it is unclear as to whether the depression causes the abnormalities or the depression is a result of the abnormalities.

Page 53: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler
Page 54: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatment of Mood Disorders

Page 55: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatments:• Unipolar Mood Disorders

– Cognitive Behavioral Therapy– Antidepressant Medication

• Bipolar Mood Disorders– Lithium– Anticonvulsant Medication– Psychotherapy

• Others– Electroconvulsive Therapy– Vagus Nerve Stimulation– Transcranial Magnetic Stimulation

Page 56: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Behavioral Therapy

• CBT combines both cognitive therapy and behavioral therapy– Cognitive Therapy teaches

a person how certain thinking patterns are causing their symptoms-by giving them a distorted picture of what's going on in their life, and making them feel anxious, depressed or angry for no good reason, or provoking them into ill-chosen actions.

Page 57: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Behavioral Therapy

– Behavioral Therapy helps patients weaken the connections between troublesome situations and their habitual reactions to them. It also teaches them how to calm their mind and body, so they can feel better, think more clearly, and make better decisions

Page 58: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Behavioral Therapy

• Identification of Skill Deficits:– Help patient to identify deficits so that they can

learn better ways to manage life

• Evaluation of Life-Experiences– Help patient develop realistic expectations about

life, and help distinguish between what the patient needs and what they want

• Self-talk– Help patient identify negative self-talk, teach them

how to combat these thoughts and to replace them with positive thought

Page 59: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Behavioral Therapy

• Automatic thoughts– Help patient identify negative automatic thoughts

and ways to replace these thoughts with positive ones

• Irrational ideas and Beliefs– Teach patient how to identify their irrational

thoughts and how to differentiate between irrational and rational thought

• Overgeneralizing and Catastrophizing– Help patient identify and change negative

overgeneralizations

Page 60: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Cognitive Behavioral Therapy

• Cognitive Distortions– Help patient determine what evaluations

are distortions by providing objective feedback of their evaluations of the world

• Pessimistic Thinking– Help patient develop more optimistic view

of world

Page 61: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatment:Antidepressants

• Four types of drugs are used in the treatment of depression and other associated mood disorders:– Tricyclic antidepressants– Monoamine Oxidase Inhibitor– Selective Serotonin Reuptake

Inhibitors– Serotonin Norepinephrine

Reuptake Inhibitors

Page 62: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Tricyclic Antidepressants

• From 1960s until late 1980s, tricyclic antidepressants represented the major pharmaceutical treatment for depression

• They still provide the surest antidepressant response for moderately to severe depression

Page 63: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Tricyclic Antidepressants

• TCAs work by increasing the concentration of norepinephrine and serotonin in certain regions of the CNS

• TCAs impede the reuptake of norepindephrine and serotonin

• They are safe and effective for up to 80% of patients

Page 64: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Tricyclic Antidepressants

• There are two broad chemical classes:– Tertiary Amines

• They have a greater effect in boosting serotonin than norepinephrine.

– amitriptyline, imipramine, trimipramine and doxepin

– Secondary Amines• Greater increase of norepinephrine levels

– nortriptyline, desipramine, and protriptyline

Page 65: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Monoamine Oxidase Inhibitors

• MAOIs treat depression by inhibiting the effect of monoamine oxidase which causes the concentrations of serotonin, norepinephrine and dopamine to increase

• Most doctors will not prescribe MAOIs unless a patient is not responding to other antidepressants

Page 66: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Monoamine Oxidase Inhibitors

• Definitely Effective– Atypical Depression– Major Depression– Dysthymia– Melancholia– Panic Disorder– Bulimia – Atypical facial pain– Anergic Depression– Treatment-resistant

depression– Parkinson’s Disease

• Other Possible Uses– Obsessive-

complusive Disorder– Narcolepsy– Headache– Chronic pain

syndrome– Generalized anxiety

disorder

Page 67: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Selective Serotonin Reuptake Inhibitors

• SSRIs work by inhibiting the reuptake of serotonin into the neuron that made it

• Includes fluoxetine and paroxetine

Page 68: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Serotonin Norepinephrine Reuptake Inhibitors

• This class of drugs is most recent addition to the family of antidepressants and has a structure and chemical profile that distinguishes them both tricyclic antidepressants and SSRIs.

• Work by increasing levels of Serotonin and Norepinephrine by inhibiting their re-absorption back into the cell.

Page 69: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Venlafaxine

• Venlafaxine inhibits serotonin and norepinephrine reuptake without significant effects on muscarinic, cholinergic, histaminic, or alpha-andrenergic receptors.

• Therefore, venlafaxine activity is similar to tricyclics and SSRIs but has a less adverse side-effect profile.

Page 70: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bupropin

• Bupropin is the newest drug for treating depression, although the exact neurochemical mechanism is not known– Does not inhibit monoamine oxidase or inihibit the

reuptake serotonin and norepinephrine– Does inhibit the reuptake of dopamine to some

extent

• It is a stimulant type drug that is used in the treatment of major depression.

Page 71: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatments:Antidepressants

• 50-65% of people given an antidepressant show much improvement over 3 months, compared to 25-30% of people given a placebo. – Indicates that although drug is effective,

antidepressants, like most medicines, may have some benefits due to placebo affect

Page 72: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatments:Antidepressants

• Medication must be used every day or at every time prescribed. If not taken correctly treatment will not be effective and may have adverse effects.

• Antidepressants will usually take 1-2 weeks work, however some may take up to six weeks

Page 73: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatments:Antidepressants

• On the basis of clinical research and experience, the consensus is that most people can be taken off their antidepressants after six to eight months of clinical response without doing worse than patients continuing on the drug

Page 74: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar Treatments

• Psychiatric Management

• Acute Treatment

• Maintenance Treatment

Page 75: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Psychiatric Management

At this time, there is no cure for bipolar disorder; however, treatment can decrease the associated morbidity and mortality.

Page 76: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar Treatments:Lithium

• Lithium is prescribed to people with bipolar disorder to even out the “highs” and “lows.”

• Because bipolar disorder requires long term treatment, a patient may have to take Lithium for many years, often in combination with other antidepressants

Page 77: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar Treatments:Lithium

• Lithium interferes with the synthesis and reuptake of chemical messengers by which nerves communicate with each other (neurotransmitters). Lithium also affects the concentrations of tryptophan and serotonin in the brain.

• Lithium's effects usually begin within one week of starting treatment, and the full effect is seen by 2 to 3 weeks.

Page 78: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Bipolar Treatment:Anticonvulsants

• Often prescribed to patients who do not respond to lithium

• Include carbamazepine (Tegretol) or valproic acid (Depakene)

• More than 50% respond positively to these drugs

• Reduce the frequency and severity of relapse

Page 79: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler
Page 80: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatments:Electroconvulsive Therapy– Patient is put to sleep and temporarily paralyzed,

so that their muscles do not contract and cause injuries like fractures. An electric current is then run through the brain to initiate a seizure.

– ECT is sometimes the most effective, rapid method of treating severe major depressive disorder (MDD).

• for patients with poor response to medications, • poor tolerance of usual antidepressants, • severe vegetative symptoms, • or psychotic features

Page 81: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Treatment:Vagus Nerve Stimulation

• VNS stimulates the limbic system, a group of related structures that affect mood, motivation, sleep, appetite, alertness and other factors commonly altered by depression.

• VNS is delivered to the left cervical vagus nerve by the NeuroCybernetic Prosthesis (NCPâ) System which is implanted just under the skin in the left chest area.

– Delivers a pre-programmed, intermittent electrical pulse to cervical vagus nerve 24 hours a day

Page 82: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Transcranial Magnetic Stimulation

• TMS is a procedure in which the electrical activity in the brain is influenced by a magnetic pulse.

• This procedure can be used to alter function of certain areas of the brain, especially those involved in depression

Page 83: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects of Treatments

Page 84: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects:Tricyclics

• Initially:• they cause blurred

vision• Constipation• Light-headedness when

standing or sitting up suddenly

• Dry mouth• Difficulty urinating• Feelings of confusion• Cognitive Dysfunction

– A small percentage of people will have other side effects such as:

• sweating, a racing heartbeat, low blood pressure, allergic skin reactions or sensitivity to the sun.

– Side effects usually disappear once therapeutic effects if medication take hold

Page 85: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects:Tricyclics

• More serious side effects, although rare, can be aggravation of narrow angle glaucoma and seizures

• Some tricyclic side effects relate to the fact that these medications have similar effects on other neurotransmitters in the CNS, notably histamine and acetylcholine

and incidence of arrhyhmias• Phenothiazines Psychosis, agitation• Barbiturates Increase heteocyclic metabolism• Cimetidine Blocks metabolism of

heterocyclics• Haloperidol Can block metabolism of

heterocyclics• Methylphanidate Blocks metabolisms of

heterocyclics

Side Effects:MAIOs

• The side effects of MAOIs are generally more severe or frequent than for other antidepressants

Page 88: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects:MAIOs

• Drowsiness • Constipation • Nausea • Diarrhea • Stomach upset • Fatigue • Dry mouth • Dizziness • Low blood pressure • Lightheadedness, especially

when getting up from a lying or sitting position

• Decreased urine output • Decreased sexual function • Sleep disturbances • Muscle twitching • Weight gain • Blurred vision • Headache • Increased appetite • Restlessness • Shakiness • Trembling • Weakness • Increased sweating

Page 89: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Drug Interactions:MAOIs

• Because of the extensive inhibition of monoamine oxidase by MAOIs enzymes raises the potential for a number of drug interactions.– Many of these interaction occur with over-

the-counter medications

Drug Interactions:MAOIs

Drug InteractionOther MAOIS Increase risk for side effect;

covulsionsTCAs, Carbamazepine, Hypertension; convulsionsCyclobenzaprineSSRIs Serotonin SyndromeStimulants (dextromamphetamine); Increased blood pressureBusironeMeperidine Potentially fatal interactionDextromethorphan Brief psychosisDirect Sympathomimetics Increased blood pressureIndirect Sympathomimetics Hypertensive crisis possibleOral Hypoglycemics (insulin) May worsen hypoglycemiaFenfluramine, L-Tryptophan Serotonin Syndrome possible

Page 91: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Food Interactions:MAOIs

• MAOIs inhibit monoamine oxidase in gut that is responsible for the break down of tyramine. A build up of tyramine can lead to a sudden increase in blood pressure and a chance of heart attack or stroke.

• Food Restrictions– Avoid:

• Cheese, overripe aged fruit, fava beans, sausage, salami, sherry, liquors, sauerkraut, monosodium glutamate, pickled fish, brewer’s yeast, beef and chicken liver, fermented products, red wine

– Used in moderation• Coffee, chocolate, colas,

tea, soy sauce, beer, other wines

Side Effects:SSRIs

• loss of appetite, weight loss • increased appetite, weight gain • allergic reactions • dry mouth • irritability / anxiety • sleeplessness • drowsiness • headache • shaking • dizziness • fits / convulsions • disturbance of sexual function (but

this is also a feature of depression) • sweating • bruising • manic or hypomanic behaviour

• shaking • dizziness • fits / convulsions • disturbance of sexual function

(but this is also a feature of depression)

• sweating • bruising • manic or hypomanic behaviour • abnormal movements • low sodium level • suicidal ideas• abnormal movements • low sodium level • suicidal ideas

Page 93: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Drug Interactions:SSRIs

• Although the potential for interaction does exist, SSRIs are not associated with many of the interactions are seen with other antidepressants– Paroxetine and fluvoxamine have been

associated with increased bleeding when given with wafarin

– Does not effect Lithium levels

Page 94: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Suicide and SSRIs

• There is evidence that the use of antidepressants, especially SSRIs, can cause an increase in suicidal thoughts, however it does not show an increase in cases.– A severely depressed patient, or those with bipolar

syndrome in a “low” phase, usually only have the energy to focus on their low. As the medication begins to take affect they will have an increase in energy and suicidal thoughts as they transition from their “low” or depressed episode. It is this time when the patient is still in a “depressed state of mind,” that they are able to think more about and idealize suicide because oh their higher energy level.

Side Effects:SNRIs

• Nausea and vomiting• Dizziness• Insomnia • Sleepiness• Abnormal dreams• Constipation• Sweating• Dry mouth

• Yawning• Tremor• Gas• Anxiety • Agitation• Abnormal vision• Headache• Sexual dysfunction

Page 96: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects: Bupropin• 28% of patients will lose five pounds or more• 0.04% of patients will experience seizures

– Common: Agitation, constipation, diarrhea, dizziness, dry mouth, headache, increased perspiration, insomnia, nausea, vomiting

– Rare: Acne, blurred vision, chest pains, chill, coordination problems, confusion, decrease in white blood cell count, fainting, fever,hair color change

Page 97: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Withdrawls:SNRIs

• Stopping treatment with SNRIs, especially when done suddenly, can cause withdrawal-like symptoms:

– nausea, vomiting, anxiety, diarrhea, agitation, confusion, headaches, nightmares, coordination changes, or skin-tingling or shock-like sensations

» Sometimes referred to as discontinuation syndrome

Page 98: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Side Effects:Electroconvulsive Therapy

• Anxiety or nervousness • Gastrointestinal distress

(nausea and diarrhea)• Headache • Insomnia • Rash • Slight weight loss • Sexual impotence in men

(about 10%) • Lose of interest in sex for

both men and women; inability to achieve orgasm

The Chris Pittman Case

• In 2001, the 12 year boy shot and killed his grandparents while being under the influence of Zoloft, a popular antidepressant for the previous couple of days

Page 100: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

The Chris Pittman Case

• Defense attorneys argued that Chris suffered adverse reactions to the drug including akathisia (a neurological reaction characterized by extreme internal restlessness, which has been associated with suicide and violence), emotional blunting, mania and psychosis with testimonies by Chris’s aunt and sister

Page 101: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

The Chris Pittman Case• Former FDA scientist Dr. Richard Kapit, who

had approved Zoloft for human clinical trials even testified in Chris’s defense stating that some antidepressants can alter the behavior of people under 18, causing mania and even suicide

• Chris was charged and sentenced as an adult on February 15, 2005, and is now serving 30 years in prison

Ethics

Page 103: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Ethics

• Ethical issue arises over a depressed patients ability to make decisions concerning treatment.

• An elderly patient that has been diagnosed with depression has recently become gravely ill, requiring dialysis.

Page 104: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Ethics

• If you are not given an effective dosage of antidepressant medication, suicide rates increase. Is the hit-or-miss method of treatment with medication ethical?

• Untreated Depression has a high risk of suicide that accompanies the disorder

Page 105: Diagnosing and Treating Mood Disorders: The Science and Ethics Chris Trimble, Leo Huizar, Fredah Kabbech, Megan Sieveke, Brandon Butler

Ethics

• 54% of patients with bipolar disorder are misdiagnosed as having depression

• Misdiagnoses and treatment of patients with bipolar disorder as having a unipolar disorder can magnify the patients symptoms

• Many antidepressants can cause a patient with bipolar disorder to have exaggerated and prolonged “highs” and “lows”

• Should we be quick to treat Depression with medication when misdiagnosis can have serious consequences.
