Statistics

•More than 5.3 million Americans are living with TBI related disabilities

•Average Span of a person with TBI injured before age 30 is 78.6 years

NORMAL AGING

Physical patterns:

Page 6: Aging and Brain Injury

Aging• Mobility Problems• Hearing and Vision Loss• Health Issues• Decreased Memory• Depression• Loss of peers/social

withdrawl

TBI• Mobility Problems• Sensory Loss• Health issues• Memory & Cognitive

Problems• Depression• Loss of peers/social;

withdrawl

Page 7: Aging and Brain Injury

What Barriers Increase Over Time?

• Aging Caregivers• Social Network & Support Failure• Functional Capacities Decrease• Loss of Life Activity Focus• Higher rates of Psychological Problems• Emergence of Additional Health Problems

Page 8: Aging and Brain Injury

Other Factors Affecting Health

• Economic and Social Status• Limited Resources/Insurance• Reduced Health Literacy• Poor Health Practices due to Cognitive

Problems• Increased Rates of Obesity, Hypertension,

Depression and Diabetes

Page 9: Aging and Brain Injury

Chronic Medical Issues• Seizure Disorder• Respiratory Problems• Late Onset Swallowing Problems• Diabetes • Skin Integrity• Circulatory Problems• GI Probles• Headaches• Pain

Page 10: Aging and Brain Injury

Caregiver Issues

• Age

• Health

• Physical Capacity

• Finances

Page 11: Aging and Brain Injury

Accelerated Decline

• Early Onset of Physical and Cognitive Decline

• Psychological Response to Long Term Disability• Gains Made in Rehab Erode

• Level of Independence Decreases

Page 12: Aging and Brain Injury

Research •Enhanced physical decline

–Colantonio, Ratcliff, Chase, & Vernich, 2004•Increased incidence of arthritis among 35-44 y/o’s•Increased prevalence of visual and hearing impairments•Increased prevalence of epilepsy•Sleep problems

(Colantonio et al., 2004)

Page 13: Aging and Brain Injury

Research

•Enhanced cognitive decline:–Corkin, Rosen, Sullican, & Clegg, 1989

•Longitudinal study examining 314 veterans sustaining head injury•Results: found that head injury was associated with decline on tests of cognitive functioning

–De Beaumont et al., 2009•Examined athletes sustaining their last concussion since years playing sports•Results: significant reductions in episodic memory, motor execution slowing, and decline with response inhibition 30 years post-injury

(De Beaumont et al., 2009; Corkin et al., 1989)

Page 14: Aging and Brain Injury

TBI Is A Chronic Disease

• Life Expectancy• Endocrine Dysfunction• Cognitive Decline• Psychiatric Conditions• Development of Neurodegenerative

Conditions

Page 15: Aging and Brain Injury

Risk Factors for Increased Mortality

• Advanced Age at Time of Injury• Seizures• Employment Status• Substance Abuse• Psychiatric Disorder• Physical Impairment

Page 16: Aging and Brain Injury

Causes of Death

• Seizures• Pneumonia/Other Respiratory• Sepsis• Choking• Suicide*• Substance Abuse Related*• Accidental Injury* *mild tbi

Page 17: Aging and Brain Injury

Endocrine Dysfunction

• Growth hormone insufficiency

• Hypothyroidism

• Gonadotropin Decrease

• Hypopituitarism

Page 18: Aging and Brain Injury

NeuroDegenerative Disorders

• Increased risk of brain atrophy

• Lack of neuronal reserve

• Breakdown of BBB

• Accumulation of protein

Page 19: Aging and Brain Injury
Page 20: Aging and Brain Injury

TBI & NeuroDegenerative Disorders

• Moderate to Severe TBI Associated with Alzheimer’sDisease

Parkinsonism

• Mild TBI ??

Page 21: Aging and Brain Injury

Age at Injury & Outcomes

• Higher rates of severe disability, PVS, and death for >55

• Severe Disability, PVS and death rates for ages 15-25 was 50% of the rate for those >55

Page 22: Aging and Brain Injury

Age & Recovery

• Older brain has decrease ability to repair itself

• Greater likelihood of repeated insults to the brain based on age

• 40-50% increase in the odds of poor outcome for every 10 yrs of age

Page 23: Aging and Brain Injury

TBI In Older Adults

FallsRisk Factors•Increasing Age•Cognitive Impairment•Medication Side Effects•Alcohol Intoxication

Page 24: Aging and Brain Injury

CASE STUDY 1

Page 25: Aging and Brain Injury

Case Study 2

Page 26: Aging and Brain Injury

Final Thoughts

• TBI is a chronic disease with lifetime effects

• TBI Increases the risk of multiple health problems

• Resources are needed for long term follow up and increased care
