 Clinical Diagnostic Criteria of Frontotemporal Dementia (FTD)

   Clinical Diagnostic Criteria of Frontotemporal Dementia (FTD)


 

Based on the foregoing, the recommended clinical criteria for diagnosing FTD are

 

(1). The development of behavioral or cognitive deficits manifested by either

                (a). early and progressive change in personality, characterized by

              difficulty in modulating behavior, often resulting in appropriate

              response or activities,  or

                (b). early and progressive change in language, characterized by

                          problems with expression of language or severe naming difficulty                              and problems with word meaning

 

(2). The deficits outlined in 1a or 1b cause significant impairment in social or

          occupational functioning and represent a significant decline from a previous

          level of functioning.

 

(3). The course is characterized by a gradual onset and continuing decline in

          function   

(4). The deficits outlined in 1a or 1b are not due to other nervous system

        conditions (eg. hypothyroidism), or substances-induced condition.

 

    (5). The deficits do not occurr exclusively during a delirium.

 

    (6) The disturbance is not better accounted for by a psychiatric diagnosis (eg.

      depression)
