[Pick's disease in senescence].
We report two patients with Pick's disease in senescence. Patient 1 is a 78-year-old woman. She developed abnormal behavior at the age of 76 years. Neurological examination at age 76 revealed poor rapport, easy angriness, "Denkfaulheit", oral tendency, and slight dementia [WAIS (Wechsler Adult intelligence Scale) total IQ 62]. Cranial CT scan and MRI showed bilateral atrophy of the frontal and temporal lobe, especially of the temporal lobe. Patient 2 is a 73-year-old man. He developped sexual abnormal behavior and "triebhafte Hemmungslossigkeit" at the age of 71 years. Neurological examination at age 72 revealed poor rapport, lack of spontaneity, easy angriness, "Denkfaulheit", and slight dementia [WAIS total IQ 91]. Transient "stehende Redensarten" was noticed. Cranial CT scan and MRI showed bilateral atrophy of the frontal and temporal lobe, especially of the frontal lobe. To our knowledge, Pick's disease with an onset in the senescence is very rare. Pick's disease should be included in the differential diagnosis of abnormal behavior in the senescence.
