What Is Dementia?
Dementia is not a specific disease, but rather a term used to describe a range of symptoms related to a decline in memory and other cognitive skills that impair a person’s ability to perform everyday activities. Alzheimer’s disease, the most common form of dementia, accounts for 60 to 80 percent of cases, followed by vascular dementia, which is a form of dementia associated with the aftermath of a stroke. Other forms of dementia may be reversible, including some thyroid problems and vitamin deficiencies (e.g., vitamin B12 deficiency). Dementia is caused by damage to the brain cells, which interferes with sufferers' ability to communicate, impairing normal thinking, behavior and feelings.
Five million Americans, or roughly 1 in 9 people older than 65, suffer from Alzheimer’s disease, according to the Alzheimer’s Association. Almost two-thirds of Alzheimer’s patients are women. While symptoms of can vary greatly, at least two of the following must be significantly impaired for a person to have dementia: memory, communication and language, ability to focus and pay attention, reasoning and judgement, or visual perception.
