What are two common behaviors caused by Alzheimer's disease?

Common behavioral symptoms of Alzheimer's include sleeplessness, wandering, agitation, anxiety, and aggression. Scientists are learning why these symptoms occur and are studying new treatments — drug and nondrug — to manage them.

Can Alzheimer's be prevented?

As the exact cause of Alzheimer's disease is still unknown, there's no certain way to prevent the condition.

Can you test yourself for Alzheimer's?

The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities.

What are the 3 stages of Alzheimer's?

Alzheimer's disease typically progresses slowly in three general stages: early, middle and late (sometimes referred to as mild, moderate and severe in a medical context).

How can you tell if someone has dementia or Alzheimer's?

There is no one test to determine if someone has dementia. Doctors diagnose Alzheimer's and other types of dementia based on a careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior associated with each type.

Can Alzheimer's come on suddenly?

A small number of people have “early-onset” Alzheimer disease, which starts when they are in their 30s or 40s. People live for an average of 8 years after their symptoms appear. But the disease can progress quickly in some people and slowly in others.

Is Alzheimer's inherited from mother or father?

We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.

Does Alzheimer's run in families?

Family history

Those who have a parent, brother or sister with Alzheimer's are more likely to develop the disease. The risk increases if more than one family member has the illness. When diseases tend to run in families, either heredity (genetics), environmental factors, or both, may play a role.
