Dementia is a general term (not a specific disease) that describes a group of symptoms which negatively impacts memory severe enough to interfere with daily life.
Alzheimer’s is the most common form of dementia with 60-80% of cases, while Vascular Dementia is the second most common dementia type. Nevertheless, there are many other conditions that cause symptoms of dementia. As opposed to Alzheimer’s, some forms of dementia are reversible.
