What is Alzheimer's disease?
Alzheimer’s disease (AD) is a degenerative brain disease and the most common form of dementia. It is an irreversible, progressive 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 in their mid-60s.
Signs & Symptoms
The signs and symptoms of AD are variable in severity and frequency and emerge at different times during the course of condition.
Short term memory loss and confusion
Difficulty learning new things
Delusions and disorientation
Inability to recognize common things
AD impacts nearly every aspect of a person's life as it progresses.
As AD progresses, behavioral symptoms may manifest, resulting in difficulty with self-care, irritability, restlessness, and personality changes. AD may also present with psychological symptoms including depression, hallucinations, and paranoia.
Estimates of the prevalence of AD vary, but experts suggest that more than 5.7 million Americans may be living with AD. Worldwide dementia cases are projected to grow to over 130 million by 2050.
