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.
Drug induced dementia
is a broad term that refers mostly to delirium. Drug-disease interaction, such as in patients with dementia where a risk of delirium is present, is enhanced due to diminished “cognitive reserve.” Dementia is the most severe form of cognitive deficit and is sometimes referred to as brain failure. Cerebral insufficiency is a general term indicating a decline of mental function. It does not specify the cause, but instead the clinical effects, which may be mild, moderate, or severe (dementia).
