DEFINITION OF THE DEMENTIA SYNDROME

The characteristic clinical feature of dementia is the presence of cognitive decline sufficient to cause functional impairment. Criteria for dementia are defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM IV). When dementia has been confirmed, the differential diagnosis can begin. The onset of progressive dementia is usually insidious. The first signs are forgetfulness, personality change, changes in the capacity to carry out the ordinary tasks of daily living, and repetitive behavior.

In addition, delusions and paranoid or antisocial behavior may be experienced in more advanced dementia. The exact clinical symptoms vary between patients and the duration of the illness may be long or short, taking from months (e.g. Creutzfeld-Jakob disease) to years (average 9 years in AD). Dementia has diverse etiologies. One challenge is to make a correct differential diagnosis.
