PSYCHIATRIC AND BEHAVIORAL MANIFESTATIONS OF NORMAL-PRESSURE HYDROCEPHALUS

Seven patients with psychiatric and behavioural manifestations of norm al-pressure hydrocephalus are described. There is little disagreement about the classical triad of symptoms. However, it requires a high ind ex of suspicion when a patient presents with non-specific psychiatric and behavioural symptoms. Clinicians must be alert to the possibility when positive findings point to the diagnosis of normal-pressure hydro cephalus, namely gait disturbance, incontinence soft neurological sign s, history of hypertension and no previous psychiatric history.
