Abstract
The “higher brain dysfunction” illustrates various cognitive and behavioral consequences resulted from organic brain damage. We should note that this concept comprehensively involves various and heterogeneous brain-based symptoms. Among them, three types of problems were described which may frequently be consulted in psychiatric clinics. These included (1) subjective impairment, (2) the third party impairment, and (3) application of psychiatric handicap. On one hand, patients with such “higher brain problems” are difficult to be appropriately evaluated and treated even in psychiatry service. On the other hand, multi-disciplinary collaboration including medical doctors and paramedical staff is crucial for overcome patients' problems.
