What is Alzheimer?

Alzheimer’s is a type of dementia that causes problems with memory, thinking and behavior. Symptoms usually develop slowly and get worse over time, becoming severe enough to interfere with the activities of daily living.

Alzheimer and Dementia

Alzheimer’s is the most common form of dementia, a general term for memory loss and other intellectual abilities serious enough to interfere with daily life. Alzheimer’s disease accounts for 50 to 80 percent of all cases of dementia.

Alzheimer’s is not a normal part of aging; although the greatest risk factor is age and most people with Alzheimer’s disease are over age 65, but Alzheimer’s is not just a disease of old age. Five percent of people with the disease have early-onset Alzheimer’s disease, often appearing in their 40s or 50s.

Alzheimer’s gets worse over time. Alzheimer’s is a progressive disease, where dementia symptoms gradually worsen over several years. In its early stages, memory loss is mild, but in the more advanced stages of Alzheimer’s, individuals lose the ability to hold a conversation and respond to their environment. Alzheimer’s is the sixth leading cause of death in the United States. People with Alzheimer’s live an average of eight years after their symptoms become noticeable to others, but survival can range from four to 20 years, depending on age and other health conditions.

Alzheimer’s currently has no cure, but treatments for symptoms are available and research continues. Although current treatments for the disease cannot stop the progress of the condition, they can temporarily slow the progression of dementia symptoms and improve the quality of life for people with Alzheimer’s and their caregivers. Today, there is a worldwide effort to find better ways to treat the disease, delay its onset, and prevent it from developing.
