Frontal lobe personality syndromes. Ominous sequelae of head trauma

Head trauma frequently results in frontal lobe dysfunction. This can cause a number of personality changes characterized by disturbances in affect and in regulation of emotions. Behavioral changes and alterations in cognition may occur also and are often accompanied by neurologic signs. The changes are frequently debilitating, and unfortunately in too many cases the lesion and its effects are not reversible and the patient's prognosis for returning to useful and independent life is very poor. A well-planned approach on the part of the physician can aid patient and family in difficult adjustments during rehabilitation and afford the best chance for recovery.
