Understanding Alzheimer's Disease
Alzheimer’s disease 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 daily tasks. 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. It accounts for 50 to 80 percent of dementia cases.
Alzheimer’s is not just a disease of old age, as up to five percent of people with the disease have early-onset Alzheimer’s (also known as younger-onset), which often appears when someone is in their 40s or 50s. Alzheimer’s is a progressive disease, where dementia symptoms gradually worsen over a number of years. In its early stages, memory loss is mild, but with late-stage Alzheimer’s, individuals lose the ability to carry on a conversation and respond to their environment.
