ABSTRACT

When the frontal lobe of the brain is affected important behavioral changes may occur mainly at the level of executive functioning, i.e., planning, decision-making, judgment and self-perception. However, the behavioral changes may be of different nature with marked indifference and apathy. We report a clinical case of an 81-year-old patient with sudden onset of behavioral changes that were initially interpreted as an acute confusional episode of infectious etiology, but actually they were due to an ischemic lesion in the frontal lobe.


O lobo frontal, quando afetado, pode provocar alterações importantes do comportamento, principalmente na função executiva: planejamento, tomada de decisões, juízo e autopercepção. Contudo, as alterações podem ser de outra natureza, caracterizando-se por marcada indiferença e apatia. É relatado aqui o caso de uma paciente de 81 anos, com alterações súbitas do comportamento, que foram interpretadas inicialmente como um quadro confusional agudo de natureza infecciosa, mas que se mostraram provocadas por uma lesão isquêmica na região frontal.
