Alzheimer's Disease Symptoms & Signs
Medical Author: Melissa Conrad Stöppler, MD
Alzheimer's disease is a common cause of dementia and its associated symptoms. Memory problems that develop slowly over time are often the main or first symptoms of Alzheimer's disease. Later symptoms can include personality changes like apathy, withdrawal, and reduced spontaneity. Trouble with abstract thinking and significant cognitive loss can develop with time. Other symptoms of the mental decline seen in people with Alzheimer's disease can include loss of orientation (to person, place, or time), agitation, irritability, quarrelsomeness, and a diminishing ability to care for him- or herself and to dress appropriately. Mood changes, wandering, erratic behavior, uncooperativeness, and anger can be seen in the later stages of the disease. Physical symptoms can include loss of bowel control or urinary incontinence.
