Identifying Schizophrenia and Bipolar Disorder from a Sea of Mimics

Michael Sean Stanley, MD

Assistant Professor

OHSU Department of Psychiatry

Identifying Schizophrenia and Bipolar Disorder from a Sea of Mimics

No Disclosures.

• Objectives:

– Understand the clinical presentation and approach to treatment of Schizophrenia and Bipolar Disorder

Psychotic disorders are:

• primarily problems of sensory processing and association, not emotion

• Exhibit profound disconnection from sensory reality

Mood Disorders are:

• Primarily problems of prolonged extreme emotional tone (mood).

• Exhibit excessive high or low mood/motivation from normal state

Psychosis

Schizophrenia

Schizophrenia

• a neurodevelopmental syndrome

• associated with functional impairments

• no single unifying cause

• emerges when environmental accelerants act upon genetic predisposition

• May be at the more severely impairing end of a spectrum of disorders.

+ -Positive Symptoms

New abnormal sx- Hallucinations

(auditory most commonly)

- Delusions- Significant

disorganization of thought/behavior

May come and go

May be responsive to antipsychotic meds

Negative Symptoms

Loss of normal fxn- Affective flattening- Anhedonia- Asociality- Alogia

A stable loss, do not fluctuate significantly once lost.

Minimally responsive to antipsychotic meds if at all.

For 6 mo or longer; Not due to medical or substance use cause.

Cognitive Symptoms

Accompany and likely precede +/- sx- Attentional problems- Slower processing- Difficulty with

planning/probsolving

- Memory problems

Prodromal sx?

May decrease to some degree with tx of pos sx, but rarely completely.

C

Positive Symptoms

Most commonly during teens-20s

Genetics:• Highly heritable – 30% of offspring• Many genes with small effect size• Some genetic overlap with other psych dx:

BPAD, MDD, Autism Spectrum DO• Genes point to multiple mechanisms

• Pathways implicated by Genes (a selection)• Synaptic function (DRD2, GlutR, voltage-

dependent calcium channels)• Synaptic plasticity• Cytoskeletal development• Immune response/modulation

Inflammatory EventsDamage Events

Inappropriate Pruning or Synaptic Changes: • Decr grey matter

• Prefrontal• Parahippoca

mpal• Temporal• thalamic

• Decr dendritic spines

Neuro-Cognitive Network Imbalance• Lack of coordination

of neural tasks• Lack of inhibition of

neural tasks

Inappropriate salience –hallucinations/delusions

Schizophrenia

Onset• One peak in men: generally adolescence to early 20s• Two peaks in women: similar as above + over 40sPrevalence• Lifetime likelihood of 0.7%Disability• 80-90% unemployed• Life-expectancy 10-20 years reduced

• Most likely due to cardiovascular and other health problems• High prev of smoking• High prev of dietary indiscretions• Low medical care use• Cardiometabolic effects of medication treatments

Schizophrenia Template Case• 19 yo male• CC: Presents for auditory hallucinations of his high school physics professor arguing

with his parents about implanting novel “microcircuits” in his body. Feels this might be true, and has shaved parts of his body to scan the “microcircuits”

• HPI (from collateral): sx began about 1 year ago, have fluctuated, and have been associated w/ performance decline at community college, last quarter his teachers expressed concern and he was on monitoring plan by student health center. Per family, throughout high school, patient displayed some thoughts of supernatural causes, but they had not caused functional problems. Gradually late in high school he became increasingly reclusive, stopped being interested in things that previously interested him, these sx have continued.

• Family Hx: Paternal uncle with schizophrenia• Exam: Medical exam benign, has never used drugs other than tobacco.• Mental Status Exam: + AH and delusions, thought blocking, appeared to attend to

internal stimuli, flat affect, paucity of spontaneous thought. • Course: saw psychiatrist who Rx’d Risperidone 2mg qhs, which significantly decreased

AH. Stopped medication after 6 mo, when noticed gynecomastia, and AH restarted.

Differential Diagnosis of Schizophrenia

Other Psychiatric Disorders• Schizophrenia spectrum• Bipolar Disorder, Manic with Psychotic features• Major Depressive Episode with Psychotic features• Body Dysmorphic Disorder

Non-Psychiatric Disorders• Medication-Induced Psychosis• Substance-Induced Psychosis• Epilepsy• Cerebrovascular Disorders• Neoplasm• Dementia with Lewy bodies• Delirium• Autoimmune: Anti-NMDA receptor encephalitis

Psychotic symptoms, such as auditory hallucinations and paranoid thinking, occur in attenuated forms in 5–8% of the healthy population

Schizophrenia Spectrum

Normal

Schiz + prominent affective sx

Delusions only, function not grossly impaired

Cognitive or perceptual distortions or behavioral eccentricities that affect social connections, but not gross biological function

Bipolar Disorder• a disorder of emotional tone

– Elevated = hypo/mania

– Low = major depressive episodes

• associated with functional impairments at peaks

• emerges when environmental accelerants act upon genetic predisposition

Bipolar Disorder

!!MANIC EPISODE!!

majordepressiveepisode

Bipolar DisorderEpidemiology of Bipolar Disorders:

• Lifetime prevalence of Bipolar Disorders is 1-3% worldwide

• Female:Male = 1:1

• Mean onset of Bipolar I DO is 18yo

• About 1/3 of patients with a parent with Bipolar Disorder will go on to have Bipolar Disorder

• Depressive Episodes are actually more common in Bipolar Disorder than are Manic/Hypomanic Episodes

• 10-15% of patients with Bipolar Disorder die by suicide, which is estimated at 12-15x greater rate than in the general population

– Corticosteroids, Isoniazid, Levodopa

• Substance-Induced Mania– Cocaine, Stimulants, Cannabis

• Hyperthyroidism• Seizures/Strokes/Neoplasm• Multiple Sclerosis• Encephalitis

Bipolar Disorder

Identifying whether a primary psychiatric or secondary disorder:• there are no pathognomonic signs to differentiate primary from secondary disorders.

• Early differentiation is observational, based on• The known epidemiology and course of primary disorders• The known presentations of primary disorders:

• History• physical exam• mental status exam

• Any confounding features

• Follow-up over long-term watching for symptoms or signs that increase or decrease probability of primary psychiatric diagnosis

Cases

• 80 yo female• CC: New onset fixed false beliefs in the last few days that

she has caused the death of multiple friends, and the only way to atone is to starve herself. No hallucinations. Affect flattened.

• HPI: Adult daughter noted that her sx started 3 weeks ago, slowly becoming more encompassing; that she had stopped going to church, was isolating more over last month, staying in bedroom sleeping a lot, eating little.

Treatments – Schizophrenia Am Fam Physician. 2014;90(11):775-782

AntipsychoticMedications

• Most of effect comes from effect at Dopamine Receptor 2 (D2)– Some medications very potent – haldol

– Some less potent – quetiapine

– A few have very minimal effects at D2 – clozapine

• effective when the levels occupy approximately 70% of D2 receptors.

• Persons with schizophrenia vary in response to antipsychotics:– 10-30% of pts with schiz get no benefit

– up to 30% may get partial benefit

– 50%+ get strong positive response

• In patients with schizophrenia recommendation is to continue antipsychotic treatment life long. – 4-30% of patients with schizophrenia will have another during their

lifetime – and no way to predict who will or won’t.

– In studies of continuation, 64% of patients randomized to placebo had relapse within 1 year, 23% of patients randomized to continuation of antipsychotic had relapse with 1 year.
