Facts About Other Dementias
Not everyone who shows signs of dementia has Alzheimer’s disease. Dementia is an umbrella term that covers many separate diseases. It is a general term for loss of memory and other mental abilities severe enough to interfere with daily life. Therefore, dementia is not a disease; it is a syndrome, or group of symptoms, associated with many separate underlying diseases. There are over 20 different types of dementing diseases but the most common is Alzheimer’s, accounting for 60-80 percent of the cases. Individuals may have more than one type of dementia.
