About Alzheimer's disease
Alzheimer's disease (AD) is a neurodegenerative disease and is the most common cause of dementia, accounting for around 60–70% of cases. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation, mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. The median life expectancy following diagnosis of dementia is three to twelve years. Co-occurring movement disorder, also known as extrapyramidal signs, multiplies risk of death by 1.6.
