Abstract
“Dementia” is a term often used in reference to Alzheimer’s disease (AD), but AD is only one of the many causes of dementia. Dementia is more than memory loss alone. If a tally were taken of the different cognitive skills potentially affected by dementia, one would find that language, spatial skills, mental speed, judgment, and a host of cognitive domains can be impaired in addition to memory. In fact, dementia is defined as a disabling level of impairment of multiple cognitive domains. Because many diseases can cause dementia, not all affect each cognitive domain to the same degree. For example, AD causes profound memory loss, but corticobasal ganglionic degeneration affects coordinated movement (praxis) more severely and progressive aphasia affects language skills more severely.
