African American Community Outreach Program (AACOP)

Alzheimer’s is an epidemic: it affects 1 in 9 Americans over 65, with a new diagnosis every 68 seconds. By 2050, 16 million Americans may battle the disease, with the cost of care jumping six-fold to $1.2 trillion.* We must accelerate Alzheimer's prevention research NOW! But 80% of studies fail because too few people sign up. Will you help change that?

ALZHEIMER’S IS AN EPIDEMIC!

African-Americans may have a 60% higher risk of type 2 diabetes, which is a risk factor for Alzheimer's and vascular dementia.

Data from a large-scale longitudinal study indicate that persons with a history of either high blood pressure or high cholesterol levels are twice as likely to get Alzheimer’s disease. Those with both risk factors are four times as likely to become demented.

The cumulative risk of dementia among first-degree relatives of African-Americans who have Alzheimer’s disease is 43.7%.

African Americans And Alzheimer's

Data from, “Alzheimer's Silent Epidemic hits Black Americans,” Report prepared by the Alzheimer’s Association and released by the Congressional Black Caucus.

There is a critical need for African-American clinical trial participants. Join a study today and help move research forward so your grandchildren when they are old, will never hear the words, “You have Alzheimer’s.”

Dementia Dementia is memory loss that is severe enough to interfere with everyday

life and ability to function, and is not part of the normal aging process. Dementia is defined as a loss of mental function in two or more areas such

as language, visual and spatial abilities, memory, thinking and reasoning skills, or judgment.

Alzheimer’s Disease Alzheimer’s Disease (AD) is the most common cause of dementia. AD is a degenerative disease that attacks the brain, begins gradually, and

progresses at a variable rate. AD results in impaired memory, thinking, and behavior and can last from 3

to 20 years from the time of onset of symptoms.

HOW TO REDUCE THE RISK FOR ALZHEIMER’S DISEASE

The relationship between hypertension, cholesterol levels and dementia is particularly relevant for elderly African-American patients because they are more likely than whites to have hypertension and/or diabetes.

Every heartbeat pumps one-fifth of our blood to our brain. Billions of brain cells need the food and oxygen carried by our blood to think, solve problems and remember. Conditions that damage our heart and blood vessels can threaten brain health also. When we take steps to reduce our risk of heart disease, diabetes and stroke, we may also reduce our risk for Alzheimer's.

Factors that Contribute to Cognitive Decline!

• Effects of hypertension and heart disease• Effects of diabetes• Sedentary lifestyle• Lack of stimulation• Stress/depression• Neurodegenerative disease

Exercise your Brain!

Rationale: Use it or lose it!You must exercise your brain in order to maintain function.

Cognitive reserve: The development of cognitive reserve may protect against cognitive decline. This may be innate or acquired earlier in life.

Ways to Exercise your Brain!•Mental stimulation

ReadingPuzzlesChallenging games

•Social engagement

•Physical exercise

Eating Well! Rationale:• Healthy diet offers

protection from CVD and obesity which are associated with increased risk of AD

• Antioxidant intake from fruits and vegetables may protect against oxidative stress

7 Super Foods That Prolong Life1. Salmon

2. Walnuts, almonds or other nuts

3. A Carrot a day for vitamin A

4. Eggs – including the yoke

5. Flax Seeds

6. Blueberries

7. Dark Chocolate or Hot Cocoa

Concluding Suggestions

Maintain your brain through:1. Exercise2. Cognitive stimulation 3. Healthy Diet4. Control blood pressure, cholesterol,

weight, and blood glucose levels5. Work to improve your memory
