Dementia & neuropsychologia, São Paulo, v. 5, n. 1, p. 58-60, 2011.1980-5764http://repositorio.bc.ufg.br/handle/ri/16762We report an 87-year-old male case of hair pulling associated with a white-matter vascular dementia (Binswanger’s disease). Trichotillomania in our case did not resolve using mirtazapine or anticholinesterasic medication. Trichotillomania seems to be related to a form of perseveration associated with dementia. The findings in this case suggest the abnormality involving white matter in the pathogenesis of trichotillomania, may constitute a defect in connectivity in the right frontal-subcortical circuit.engAcesso AbertoPerseveraçãoTricotilomaniaDistúrbio de controle do impulsoDemênciaPerseverationTrichotillomaniaImpulse-control disorderDementiaBinswanger’s diseaseDoença de BinswangerArtigo10.1590/S1980-57642011DN05010011
