What Happens Following
Brain Injury
Professor Jennie Ponsford, PhDDirector, Monash-Epworth Rehabilitation Research Centre, Epworth Hospital;
School of Psychological Sciences, Monash University,
Melbourne, Australia
Common causes of TBI
•Motor vehicle accidents
•Falls
•Cycling accidents
•Sporting injuries (football, rugby,
boxing, horse-riding)
•Assaults
Who is injured?
•2-3 males for every female
•Most injuries occur in males aged < 30 years, or in the elderly females
•Psychiatric or substance use history more common
• Improvements in medical management have resulted in a growing number of TBI survivors
Most common sites of brain injury
following TBI
Impairment of consciousness
•May range from brief clouding of consciousness or confusion, to coma persisting for months or years
•Glasgow Coma Scale used as injury severity measure
Score
3-8 ---- Severe
9-12 ---Moderate
13-15---Mild
Post-Traumatic Amnesia (PTA)
• Period of confusion and inability to lay down new memories, following emergence from coma
• Duration of PTA is measured from the time of injury until recovery from amnesia, i.e. it includes the period of coma
• Duration of PTA is an indicator of injury severity
–PTA< 24 hours = mild
–PTA 1-7 days = moderate
–PTA 7-28 days = severe
–PTA> 28 days = very severe
Sensorimotor impairments
associated with TBI
•Motor deficits - weakness, incoordination, poor
balance, poor endurance
•Sensory disturbances - smell, vision, hearing, taste
• Speech difficulties
• Swallowing difficulties
Common Cognitive Impairments
• Fatigue
• Concentration problems
• Learning and memory difficulties
• Poor planning and organization
• Concrete thinking
• Lack of initiative
• Inflexibility
• Dissociation between thinking and doing
• Impulsivity
Behavioural Changes
• Irritability/temper outbursts
•Communication problems
•Socially inappropriate behaviour
•Self-centredness
•Emotional changes - mood swings
• Lack of awareness
Recovery from TBI
•Recovery from mild TBI generally occurs within a couple of weeks
•Recovery from severe TBI is most rapid in first 3-6 months, but continues over several years
Injury effects disrupt attainment of
important life goals….
•Gaining independence from parental support
•Completing education
•Establishing a vocation
•Establishing a social network
• Forming close personal relationships
•Create dependency on family support
• There are things we can do to address these
problems

Return to Study
• With support, 86% of students returning to study passed all of their subjects
Relationship status
• Of those married/de-facto prior to injury, only 11.7% were separated or divorced at 10 years post-injury
• Of those single prior to injury 33.3% were married or de-facto at ten years post-injury
• However, 37% of the 10-year cohort reported difficulties in personal relationships and 34.9% trouble getting on with friends.
Social Isolation
• At 1 year 29.4% of TBI participants reported having lost friends or become socially isolated since the injury
• at 2 years 40.8%
• at 3 years 39%
• at 5 years 39.8%
• at 10 years 46.6%.
Sexuality
• More than 50% of people with TBI report persisting negative sexual changes post-injury
• Generally a decline in the sex drive and the frequency and quality of sexual activities
• Changes associated with fatigue, pain, depression, age, greater dependency, decline in relationship quality and self-esteem
• We need to be talking about and addressing sexual issues
Families
• There is increasing anxiety and depression 1-5 years post-injury in relatives in a direct caregiving role
• Cognitive and behavioural changes in the TBI relative are the greatest sources of stress
• Family stress is associated with unhealthy family functioning and poorer psychosocial adjustment in injured relative.
• Healthy family functioning and family support associated with resilience and better psychosocial adjustment (Perlesz et al., 1999, Douglas, 1994)

Major impediments to better outcomes
1. Higher level mobility problems
2. Memory difficulties
3. Executive dysfunction
4. Reduced attention and information processing speed
5. Fatigue and sleep disturbance
6. Social communication difficulties
7. Irritability and anger management
8. Anxiety and depression
9. Family stress
What can we do to address these issues?
• Provide access to rehabilitation
• Neuropsychological assessment of cognitive and behavioural problems
• Focus on cognitive and behavioural as well as physical problems
• Provide support for return to work and study and follow-up
• Provide support for communication and relationships
• Provide support for families
• Take a very long-term view
Identify individually meaningful goals, assess and treat in the community
• Set setting personally meaningful goals in collaboration with client and family.
• Assess and treat in the community
• Consider the individual’s pre-injury activities, interests, strengths and weaknesses, motivations, psychological state, family and social relationships and build on these
Higher level mobility(Gavin Williams et al.)
• Development of scale to assess higher level mobility (HiMAT) (Williams et al. Brain Injury, 2005, 19 (10), 833-843)
• Identification contributing impairments affecting gait and running mobility (Williams et al., 2009, 2011, 2013, 2014, In Press)
• Develop and evaluate targeted interventions– Running group (Williams & Morris, Brain Injury, 2009, 23(4),
307-312)
– Training ankle power at push-off (Williams et al., 2014, In Press)
Memory difficulties
• Assessment and training in use of environmental supports/reminders ( e.g., diaries, smartphones)
• Training in internal compensatory strategies may be effective for some individuals
Executive function
• Train goal management strategies e.g., Goal-Plan Do -Check
• Simplify tasks or provide external supports /prompts
Attention
• Modify tasks and the environment
– Building in rest breaks
– Simplifying tasks, reducing need for speed
– Removing distractions from environment
• Teach strategies to manage slow thinking or difficulty staying focused
Fatigue and sleep disturbance
• Assess all contributing factors (e.g., cognitive problems, anxiety, depression, pain)
• Modify lifestyle
• Address sleep habits (e.g., napping, sleep times)
• Teach relaxation
• Experimental approaches (e.g., light therapy)
Social Communication
• Word-finding strategies
• Training in communication and motion recognition skills (Douglas et al., McDonald et al., Togher et al.)
• Communication partner training
• Work needed on facilitation of friendships and use of social media
Irritability and anger management
• Providing strategies to manage anger
• Educating others to react appropriately
• Teaching adaptive skills or providing environmental supports to build a more positive environment
Anxiety and depression
• Providing psychological therapy, adapted to needs of person with cognitive difficulties, to modify thinking patterns and teach coping strategies
Family stress
• Provide long-term support for families
• Opportunities to share their experiences with others
• Thank you
It has been good having carers here as well. I hadn’t really thought about what they are going through.
I love helping other people. I feel like everyone is always helping me, so it is good to be able to help other people through what I’ve learned.
I give her more support now. I see things from her side a lot more. I realise with a brain injury that people are not in complete control like we are. So therefore you have to be
more understanding.
Thank you
