Alzheimer’s Disease Dementia
Dementia refers to symptoms of a decline in thinking abilities that interfere with one’s ability to carry out daily tasks independently. Alzheimer's disease (AD) is one of many causes of dementia but is the most common cause of dementia in individuals over the age of 65. In AD, abnormal protein deposits (called neurofibrillary tangles and neuritic plaques) form in the brain and destroy healthy brain cells. Commonly, these abnormalities tend to first form in brain areas that are responsible for memory. In some people with AD, however, these deposits can form in different areas of the brain in early stages and cause a decline in language functions, reasoning, visual perceptual skills or mood.
