ABSTRACT
OBJECTIVE:
Perry syndrome (PS) is a rare neurodegenerative disorder with autosomal dominant inheritance caused by point mutations in DCTN1 and characterized by parkinsonism, hypoventilation, weight loss, and psychiatric symptoms. Even though behavioral manifestation is a main feature of PS, detailed neuropsychological assessment was not performed in this cohort. In this study, the neuropsychological profile of individuals from one Polish and one Colombian family are presented.METHODS:
Detailed clinical and neuropsychological data were obtained from Polish and Colombian families. Clinical and neuropsychological examinations on the proband from the Polish family were performed 6 times over 11 years. Each of 3 individuals from the Colombian family received a clinical and neuropsychological assessment.RESULTS:
The neurologic examination showed severe parkinsonism, levodopa-induced motor fluctuations, and dyskinesias in all cases. Respiratory insufficiency was observed in 2 patients and weight loss in 1 individual. Neuropsychological assessment revealed predominant deterioration of working memory and learning capacity in the Polish patient. He also demonstrated compulsive behaviors, such as excessive shopping and eating, but only in the "on" phase. In the Colombian family, attentional deficits were present in 2 out of 3 cases. Out of 4 reported cases apathy and depressed mood were present in 2 individuals. Two cases demonstrated impulsivity and one had episodes of hypomania.CONCLUSIONS:
Both of these families revealed relatively similar neurologic and neuropsychological profiles. The Polish patient's behavioral and neuropsychological profile was mostly compatible with a behavioral variant of frontotemporal dementia. Of note, not only depression and apathy, but also impulsivity can occur in PS.Palavras-chave
