Review of the literature about this subject through Pubmed and report of the patient's medical history.

Let's show the 64-years-old male's case, with a personal record of schizotypal (without having needed previous hospitable admission) and arterial hypertension. The patient shows a set of symptoms, developing one month long, consisting of verbosity, desinhibicion, hipertimia, overheads increasing and conception delirious damage. This symptomatology, completely new in the patient, made suspect an organic origin, so he was admitted in Internal Medicine Unit, the presence of lacunar strokes were objetived in internal capsule.
