dementia

 [dĕ-men´shah]
a general loss of cognitive abilities, including impairment of memory as well as one or more of the following: aphasia, apraxia, agnosia, or disturbed planning, organizing, and abstract thinking abilities. It does not include loss of intellectual functioning caused by clouding of consciousness (as in delirium), depression, or other functional mental disorder (pseudodementia). Causes include a large number of conditions, some reversible and some progressive, that result in widespread cerebral damage or dysfunction. The most common cause is Alzheimer's disease; others include cerebrovascular disease, central nervous system infection, brain trauma or tumors, vitamin deficiencies, anoxia, metabolic conditions, endocrine conditions, immune disorders, prion diseases, Wernicke-Korsakoff syndrome, normal-pressure hydrocephalus, Huntington's chorea, multiple sclerosis, and Parkinson's disease.
