[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.

School vandalism: individual and social context.

Six hundred Israeli students responded to a questionnaire dealing with five motives for participating in vandalism: anger/frustration, boredom, erosion, aesthetics, and catharsis (Cohen, 1984). As we did not find a coherent pattern, we created a variable comprising all five motives: general motivation. Four factors accounted for motivation to participate in destructive behavior: perceived level of vandalism at school, attitude toward school, attitude toward teacher, and school anxiety. Punishment, father's level of education, sense of hope, and class level did not have an effect on motivation to participate in vandalism. It was concluded that the social context is a crucial element in school vandalism.

Behavioral syndromes in Alzheimer's disease.

The Behavioral Syndromes Scale for Dementia (BSSD) is a new instrument that showed strong internal consistency and interrater reliability in an outpatient sample of 106 patients with probable Alzheimer's disease. Factor analysis provided support for a priori symptom groupings, particularly the syndromes of disinhibition and apathy-indifference. Dependency (87%), denial of illness (63%), and motor agitation (55%) were common, while sexual disinhibition (2.9%) and self-destructive behaviors (2.9%) were rare. Virtually all symptoms were predominantly minimal to mild in severity. Patients with longer illness duration were more apathetic. Disinhibited behaviors and apathy-indifference increased with greater severity of dementia. Catastrophic reactions, aggression, and agitation were associated with greater functional impairment. There was great heterogeneity in symptom presentation. In Alzheimer's disease, several behavioral changes might be direct manifestations of underlying brain pathology, rather than being solely secondary to cognitive impairment.
