What Is Alzheimer's Disease?
Alzheimer’s disease, the most common form of dementia, is a progressive, terminal brain disorder that has no known cause or cure. It affects people’s memories, but it involves far more than simple forgetfulness. It is still not known why Alzheimer’s disease affects some people and not others. Researchers worldwide are searching for its causes and ways to prevent, diagnose, treat, and cure it. Learn about the signs and symptoms of Alzheimer’s, treatments, prevention techniques, and ways to care for yourself or a loved one.
Understanding Alzheimer’s Disease
Alzheimer’s steals the minds of its victims.
It takes a toll on families who provide the majority of caregiving. About 7 out of 10 people with Alzheimer’s or other dementias are cared for at home. Caregiving can be difficult—family and other unpaid caregivers may experience high levels of emotional stress and depression.
Indicators
Signs & Symptoms
Many people experience mild forgetfulness or memory delays, which are part of the normal aging process. We all have occasional difficulty remembering a word or someone’s name. Someone with Alzheimer’s or other types of dementia, however, will find such symptoms becoming more frequent and severe.
Memory loss
Any of us could forget where we placed our car keys. Someone with Alzheimer’s disease may place the keys in an unusual spot, like the refrigerator.
Confusion
Alzheimer’s can cause confusion, such as not even remembering the purpose of car keys in the first place.
Cognitive problems
This can include mood conditions such as depression, anxiety, irritability, apathy, and poor performance on cognitive tests.
Inability to care for oneself
The inability to communicate or care for oneself usually occurs at a later stage, and those affected generally become more unresponsive.

Risks & Prevention
Who is at Risk of Developing Alzheimer’s?
While there are many theories about what causes this disease, there is still no definitive answer.
However, there are some general risk factors to keep in mind, including:
- Diminished blood flow
- Excess accumulation of abnormal brain proteins
- Toxins
- Brain injury
- Infection
- Inflammation
- Malnutrition
Browse other potential risk factors and how to lower your risk.
By The Numbers
Facts & Figures
Nearly 7 Million
Americans age 65 and older are living with Alzheimer’s disease.
1 in 3
seniors die with Alzheimer’s or another dementia.
13 Million
people aged 65 and older are projected to have Alzheimer’s and other dementias by 2050 unless scientists develop new approaches to prevent or cure it.
Program Impact
The need for a cure is more urgent than ever.
Unless scientists can unlock the secrets of this disease, the number of cases is expected to triple by the year 2050. This epidemic could overwhelm our healthcare system.
Alzheimer’s Disease Research has funded more than $180 million in research grants since inception.
By providing initial funding for highly innovative, experimental research and creative ideas, we spark revolutionary approaches and life-saving breakthroughs for this disease. We are currently supporting 112 active scientific projects worldwide.
