[Post-traumatic brain injury behavioural sequelae: the man who lost his charm]

We portray a case of traumatic brain injury followed by symptoms of disexecutive or frontal lobe syndrome: apathy, lack of pragmatism and loss of previous abilities, specially those concerning social interaction - in particular with opposite sex - resulting in impairment of his characteristic charm. The results of the neuropsychological examination included retrieval anemic deficits with normal recognition, impaired motor dexterity and cognitive flexibility in the presence of normal intelligence. The cognitive-behavioural symptomatology contrasted with a normal neurologic examination.
