Annual Conference for Professionals in Brain InjuryApril 11, 2013
Presenters
• Jean Wood, Minnesota Board on Aging
• Mark Kinde, Minnesota Department of Health
• Michelle Barclay, Alzheimer’s Association
Overview of Session
• Normal brain changes with age• Brain injuries in older adults
– Prevalence, causes and comorbidities• Alzheimer’s Disease and other dementias
– Prevalence, identification and management• Falls prevention to reduce risk for brain injury
– community interventions
Demographics of Aging
• The baby boomers started turning 60 in 2006.• According to the 2010 Census -
In 2010, there were 683,000 Minnesotans age 65 and older.in 2030, there will be 1.3 million Minnesotans age 65 and older.
• The 85+ population is the fastest growing.
Normal Brain Changes with Aging
• Brain and spinal cord lose nerve cells and weight.
• Nerve cells may transmit messages more slowly.
• Reduced or lost reflexes or sensation may occur in some people.
• Some slight slowing of thought, memory and thinking is natural.
Brain Injury Epidemiology, MN
• When & where do brain injuries happen?• To whom?• What are the leading causes?• What other illnesses or injuries occur in
conjunction with brain injury?• What do we know about outcomes?• How much do brain injuries cost?• Who pays?

ALZHEIMER’S DISEASE AND RELATED DEMENTIA
Dementia is a loss of mental function in two or more areas such as
language, memory, or judgment severe enough to impact daily life.
23
Alzheimer’s disease is the most common cause of dementia.

Alzheimer’s Disease Risk Factors
Age Family history
Patients with a 1st degree relative have a 10-30% increased chance of developing AD (van Duijn 1991)
Genetic factors Mild Cognitive Impairment (MCI) Vascular risk factors Head injury Amyloid in the brain (PET Scan)

Progression of Alzheimer’s Disease
Early Stage: 2 - 4 years in duration
Middle Stage: 2 - 10 years in duration
Late Stage: 1 - 3 years in duration
Early Stage AD
Symptoms Interfere with everyday functioning Forgetfulness Trouble with time/sequence relationships More mental energy needed to process Trouble multi-tasking Writes reminders, but loses them Personality changes Shows up at the wrong time or day Changes in appearance Preference for familiar things
Middle Stage AD Fluctuating disorientation Diminished insight Learning new things becomes difficult Restricted interest in activities Declining recognition of acquaintances,
distant relatives, then more sig. relationships
Mood and behavioral changes Functional declines Alterations in sleep and appetite Wandering
Late Stage AD
Severe disorientation to time and place No short term memory Long-term memory fragments Loss of speech Difficulty walking Loss of bladder/bowel control No longer recognizes family members Inability to survive without total care

ALZHEIMER’S DISEASE IMPACT
Nearly 90,000 Minnesotans have Alzheimer’s disease.

5.4 million Americans have the disease.

Alzheimer’s disease is the sixth leading cause of death
in the United States.
AD is the fifth leading cause of death for those aged 65 and older.

Nearly 240,000 Minnesotans are caregivers for someone with Alzheimer’s disease.
Seventy percent of people with Alzheimer’s disease live at home.

Impact on the Caregiver’s Health
33% of Alzheimer’s family caregivers have symptoms of depression
Alzheimer’s family caregivers are more likely than non-caregivers to: Report that their health is fair to poor. Have high levels of stress hormones, reduced
immune function, slow wound healing, new hypertension and new coronary heart disease.

45
People with Alzheimer’s disease are high users of healthcare
and long-term care services.
Total cost was three times higher for Medicare beneficiaries age 65+ with AD in 2004.
Average Medicare payments per person for beneficiaries age 65+ with and without ADRDs in 2008 (2011 dollars)

47
More than seventy thousand Minnesota nursing home residents
have cognitive impairment.
48
Current data suggests that less than 35% of people with Alzheimer’s and other dementias have a diagnosis of the condition in their medical record.

COMMUNITY INTERVENTIONS TO IMPROVE IDENTIFICATION & MANAGEMENT OF AD
Benefits of Early Identification
Rule out other causes of cognitive impairment Start treatment early Better manage co-existing conditions Understand the symptoms and how to manage them Make decisions and future plans Build a support system Lower anxiety Avoid crisis-driven care Participate in clinical trials or other research

Early Intervention Goal 1: Educate about medications Goal 2: Reduce excess disability
Treat conditions that worsen symptoms or lead to poor outcomes (depression, uncontrolled diabetes or blood pressure, etc.)
Make safety part of the plan Goal 3: Educate about the disease, common pitfalls,
and actions that lead to success Taking Action Workbook
Goal 4: Encourage lifestyle changes that may reduce disease symptoms or slow symptom progression Living Well Workbook
Medical Interventions: Cognitive & Behavioral Symptoms Cholinesterase Inhibitors (early- late) -
Cognex®, Aricept®/ Donepezil, Exelon®, Razadyne®
Side Effects: nausea, vomiting, increased bowel frequency
Glutomate blocker (NMDA receptor antagonist: mid/late) - Namenda®
Goal: to maintain function and reduce impact of symptoms
Medical Treatment – Co-morbid Conditions and Behavioral Symptoms Co-morbid medical conditions
Diabetes, cholesterol, blood pressure, sleep dysregulation
Psychiatric / Behavioral Symptoms Depression Anxiety Aggression / Agitation Hyper-sexuality
Reducing Excess Disability Treat conditions that worsen symptoms or lead to poor outcomes
Depression Co-existing medical conditions (diabetes, blood pressure, sleep
dysregulation) Stop smoking, limit alcohol
Address Safety Issues Medication management Fall risk Home modification / simplification Driving assessment Gun safety Financial safety Medical emergency Employment Issues, when applicable

Falls in Older Adults
• Falls are the leading cause of injury for children and for adults 35-years and older.
• Falls and fall-related injuries among adults over age 65 are on the rise.
• MN ranks 5th among states in number of fall-related deaths.
Proven Steps to Reduce Fall Risk• Ask fall risk screening questions of the adults
you work with.• Refer individuals at risk for falls to their
physician for a comprehensive assessment.• Know your community resources. Connect
individuals to the resources that can help them take steps to reduce their risks.
