Diagnostic Parameter, Dementia

The American Psychiatric Association has established two generally accepted criteria for the diagnosis of dementia: (1) erosion of recent and remote memory and (2) impairment of one or more of the following functions:

Language misuse of words or inability to remember and use words correctly (i.e., aphasia)
Motor activity unable to perform motor activities even though physical ability remains intact (i.e., apraxia)
Recognition unable to recognize objects, even though sensory function is intact (i.e., agnosia)
Executive function unable to plan, organize, think abstractly

Symptoms often develop gradually and show a progressive deterioration in function.
