NIH - Alzheimer's Disease Genetics Fact Sheet

Many people wonder if Alzheimer’s disease runs in their family. Is it in your genes? This question isn’t easy to answer. Researchers have identified several genetic variants that are associated with Alzheimer’s and may increase or decrease a person’s risk of developing the disease. What does that mean? Let’s first learn about the role of genes.

From NIH's National Institute on Aging - An Alzheimer's Fact Sheet

Alzheimer’s disease is a brain disorder that slowly destroys memory and thinking skills, and eventually, the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear later in life.

Estimates vary, but experts suggest that more than 6 million Americans, most of them age 65 or older, may have Alzheimer’s.

The causes of dementia can vary depending on the types of brain changes that may be taking place. Other forms of dementia include Lewy body dementia, frontotemporal disorders, and vascular dementia. It is common for people to have mixed dementia — a combination of two or more types of dementia. For example, some people have both Alzheimer’s and vascular dementia.

NIH - What Do We Know About Healthy Aging?

"Many factors influence healthy aging. Some of these, such as genetics, are not in our control. Others — like exercise, a healthy diet, going to the doctor regularly, and taking care of our mental health — are within our reach. Research supported by NIA and others has identified actions you can take to help manage your health, live as independently as possible, and maintain your quality of life as you age."

NIH - Diabetes

"Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Over time, having too much glucose in your blood can cause other health problems such as heart disease, nerve damage, eye problems, and kidney disease. You can take steps to prevent or manage diabetes.

According to the Centers for Disease Control and Prevention’s National Diabetes Statistics Report, an estimated 38.4 million people in the United States, or 11.6% of the population, have diabetes. About 1 in 5 adults with diabetes don’t know they have the disease. An estimated 97.6 million American adults have prediabetes, which means their blood glucose levels are higher than normal but not high enough to be diagnosed as diabetes."

NIH - Preventing Alzheimer's Disease: What Do We Know?

"Changes in the brain occur many years before the first symptoms of Alzheimer’s disease appear. These early brain changes point to a possible window of opportunity to prevent or delay memory loss and other symptoms of dementia. While nothing has been proven yet to prevent Alzheimer’s, researchers have identified promising strategies and are learning more about what might — and might not — work."

"A 2017 review of research looked carefully at the evidence from clinical research on ways to prevent, delay, or slow Alzheimer’s and mild cognitive impairment (MCI) or delay or slow age-related cognitive decline."

"Led by a committee of experts from the National Academies of Sciences, Engineering, and Medicine (NASEM), the review found “encouraging but inconclusive” evidence for three types of interventions: blood pressure management in people with high blood pressure, increased physical activity, and cognitive training."
