Alzheimer's Disease: Overview
Alzheimer's disease is a progressive form of dementia, which is a type of neurological disorder that affects memory, language, thinking and behavior. It is the most common cause of dementia in older adults, and is generally fatal within three to nine years after diagnosis.
Symptoms
The symptoms of Alzheimer's disease vary from person to person and can range from mild to severe. Generally, they include memory loss, difficulty with problem-solving and decision-making, difficulty with language, disorientation, apathy, paranoia, changes in mood and behavior, and changes in physical functioning.
Diagnosis
Alzheimer's disease is typically diagnosed through a combination of physical and neurological exams, cognitive tests, medical history, and family history. In some cases, imaging tests may also be used to rule out other possible causes of dementia.
Treatment
There is no cure for Alzheimer's disease, but treatments are available to help improve symptoms and slow the progression of the disease. These treatments include medications that can help improve memory and thinking, and behavioral therapies that can help with managing behavior and mood changes.
Prognosis
The prognosis for people with Alzheimer's disease is generally poor. The disease is progressive, meaning it will continue to worsen over time, and is ultimately fatal. However, how quickly the disease progresses varies from person to person, and some people may live for several years after their diagnosis.
