What is Dementia?
• Not a normal part of aging• Characterized by problems with:
– Thinking– Language– Memory– Judgment – Reasoning
• Problems get in the way of how life was once lived (impaired activities of daily living)
• Many biological causes of dementia

Staggering Statistics
• 5.4 million Americans with AD• 1 in 8 older Americans has AD• 6th leading cause of death in the U.S. • Over 15 million people providing unpaid
care – 80% family caregivers
• Annual cost in 2012 = $200B

More Staggering Statistics
• By 2050, the number of Americans age 85+ will quadruple to 21 million
• The number of AD patients is expected to reach 16 million– 10 million baby boomers will get Alzheimer’s
disease
• Total cost of AD could exceed $1 trillion

Genetics
• APOE gene– We all have this gene, it helps make proteins
that carry cholesterol in the bloodstream– 3 common variations
• ApoE ε2• ApoE ε3• ApoE ε4
– ApoE ε4 increases risk for AD.

Protect Yourself from Head Injury
• Aβ (the protein that accumulates in the brain of someone with Alzheimer’s disease) levels go up after head trauma
• Persons who experience head trauma are more likely to develop Alzheimer’s disease later in life

The Heart-Brain Relationship
• Your brain accounts for 2% of your total body weight
• Your brain uses 20% of your blood oxygen/sugar
• If your brain does not get enough blood, brain cells can die
![Page 14: Alzheimer Disease: Knowledge Gained Through Research Volunteer Name Here.](https://reader035.fdocuments.in/reader035/viewer/2022062308/56649e0e5503460f94af9036/html5/thumbnails/14.jpg)
Cardiovascular Conditions Increase Risk for Alzheimer’s disease
• Cardiovascular disease
• Hypertension
• Stroke
• Diabetes
• High cholesterol
Lowering your risk for/ controlling these conditions can lower your risk for AD
![Page 15: Alzheimer Disease: Knowledge Gained Through Research Volunteer Name Here.](https://reader035.fdocuments.in/reader035/viewer/2022062308/56649e0e5503460f94af9036/html5/thumbnails/15.jpg)
A healthy diet can go a long way!• Several studies link diet to dementia
• Foods high in fat and cholesterol increase risk for conditions on previous slide
• Daily consumption fruits and vegetables reduced risk for all-cause dementia in one study
• Weekly consumption of fish associated with reduced risk for AD
Barberger-Gateau, et al. Neurology 2007.

Some Data Suggests Particular Dietary Ingredients May Be HelpfulAntioxidants• Vitamin E - oils, nuts, fortified cereals• Vitamin C – citrus fruits• Folate - leafy green vegetables (spinach), citrus fruits• Cruciferous vegetables - broccoli, cauliflower• Vitamin B12 – meat, fish, poultry, eggs, milk• Resveratrol - red wine • Docesahexaenoic acid (DHA) - omega-3 fatty acidOthers• Curcumin - curries (anti-oxidant, anti-inflammatory) • Soy Isoflavones - hormone-like compound

Mediterranean Shopping List
• Fish (omega-3 fatty acids; salmon, herring, mackerel, other cold-water fish)
• Fruits and vegetables (antioxidants and anti-inflammatories; leafy greens like kale, spinach, brussel sprouts, and collard greens, deeply hued produce like eggplant, bell peppers, tomatoes, blue berries, strawberries, and blackberries
• Olive oil (monounsaturated fat; extra virgin)
• Nuts (FDA recommends 1.5 oz/d; walnuts, pine nuts, pistachios, almonds)

Cognitive Activity may lower risk
• In a study controlling for age, education, and other background variables, cognitively inactive persons over the age of 65 were 2.6 times more likely to develop AD
Wilson RS, et al., Neurology. 2007;69:epub.

Keep active (mentally and physically)Longitudinal studies show that persons
with higher level of activity are less likely to
develop dementia• Puzzles
– Crossword– Sudoku
• Traveling• Knitting• Gardening• Reading

Being active is good for you!• There is much data to
support the importance of physical activity and its ability to lower risk for dementia
• Framingham Study– Moderate to heavy
physical activity is associated with a reduced risk for dementia

Alzheimer’s Care
• Diagnosis is important– Rule out other causes of cognitive impairment– Begin appropriate treatments– Make a plan
• Work with appropriate physician– Primary care– Geriatrician– Psychiatrist/Geriatric Psychiatrist– Neurologist
![Page 23: Alzheimer Disease: Knowledge Gained Through Research Volunteer Name Here.](https://reader035.fdocuments.in/reader035/viewer/2022062308/56649e0e5503460f94af9036/html5/thumbnails/23.jpg)
FDA Approved AD Treatments
• Aricept® (donepezil)—all stages• Razadyne® (galantamine)—mild to moderate• Exelon® (rivastigmine)—mild to moderate• Namenda® (memantine)—moderate to severe
• None are approved in people with mild cognitive impairment or normal memories
• None have been shown to slow the course of Alzheimer’s disease

How to Assess Information
• Gingko Biloba• Coconut oil• Aluminum• Flu shots• Many, many more
• Talk to your doctor before you begin any new medication or supplement

Current Research Toward Disease-Modifying
Therapies• Treatments that prevent or reduce the
formation of Aβ and amyloid plaques• Treatments that removed Aβ and
amyloid plaques from the brain• Treatments that reduce tau (the protein
in neurofibrillary tangles)• Neuroprotective strategies

Moving Earlier More Efficiently
• AD is an insidious neurodegenerative disorder

What Can YOU do?
• Everyone can contribute• Consider the three –ates
Advocate Donate Participate
![Page 28: Alzheimer Disease: Knowledge Gained Through Research Volunteer Name Here.](https://reader035.fdocuments.in/reader035/viewer/2022062308/56649e0e5503460f94af9036/html5/thumbnails/28.jpg)
Advocate• AD research and care support are
underfunded • Contact local, state, and federal elected
officials and tell them of the importance of AD research and services
• Consider participating in California State Advocacy Day (contact the Alzheimer’s Association for more information)

Donate
• No gift is too small• Federal funding levels below 10%• Private philanthropy is important and
supports high risk/high reward science• Some employers do “matching gifts”• Easton Center is nonprofit = tax write off

Participate• Research cannot advance without participants
– Minority participants are underrepresented in research
• Who can participate?– People with AD and other dementias– People experiencing mild memory problems– Older adults with normal memory
• If you are interested in being informed of research opportunities, consider enrolling in the Easton Center’s Potential Subject’s Database

Summary• Alzheimer’s Disease is the most common cause of
dementia• There are lifestyle risk factors for Alzheimer’s
disease• There are 4 current FDA-approved treatments for
Alzheimer’s disease, but none slow or prevent it• Research is actively pursuing better treatments
and diagnostic tools• Researchers need your help!
