Doctor's Notes on Dementia, Symptoms, Warning Signs, Types, Causes, and Treatment
The term dementia refers to a collection of symptoms brought about by damage to or loss of brain cells. Dementia is not a disease but a group of symptoms and signs that are caused by a number of different conditions. Some causes of dementia include Alzheimer disease, vascular dementia, traumatic brain injury, Huntington disease, alcoholic dementia, and Lewy body dementia.
Symptoms and signs of dementia include memory loss, difficulty finding the right word, impaired judgment, trouble with activities of daily living, personality changes, impulsivity, inability to care for oneself, and difficulty recognizing others. Other associated symptoms and signs in people with dementia can include repetition of words, lack of ability to communicate, loss of bowel and bladder control, problems concentrating and focusing, and weight loss.
