Alzheimer

--(--)

Alzheimer's disease is a neurodegenerative disease that usually starts slowly and progressively worsens. It is the cause of 60–70% of cases of dementia.The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, self-neglect, and behavioral issues.The typical life expectancy following diagnosis is three to nine years. The cause of Alzheimer's disease is poorly understood. There are no medications or supplements that have been shown to decrease risk. No treatments stop or reverse its progression, though some may temporarily improve symptoms. As of 2020, there were approximately 50 million people worldwide with Alzheimer's disease.Alzheimer's disease is ranked as the seventh leading cause of death in the United States.
