Alzheimer’s Disease is the Most Common Form of Dementia

Dementia is not a single disease; instead, it refers to symptoms related to a decline in memory, reasoning and thinking that are severe enough to interfere with daily life. Dementia stems from a variety of diseases and even injuries that affect the brain and lead to impairment. Although Alzheimer’s disease is the most recognized form of dementia, there are several other types, each with its own set of symptoms and causes. The four most common types of dementia are Alzheimer’s disease, vascular dementia, Lewy body dementia and frontotemporal dementia.
