Common causes of memory loss, Alzheimer's and dementia
Dementia is the progressive decline in cognitive function due to damage or disease in the brain beyond what might be expected from normal aging. Particularly affected areas may be memory, attention, language, and problem solving. In the later stages of the condition affected persons may be disoriented to time, place and person.
