A case of chronic subdural hematoma with anxiety states and concomitant regression-like symptoms.

The authors described an epileptic suffering from head trauma in whom anxiety states and concomitant regression-like symptoms masked the diagnosis of chronic subdural hematoma. Along with the occurrence of chronic subdural hematoma, psychic symptoms were manifested including the anxiety and regression of personality. However, after the chronic subdural hematoma was neurosurgically evacuated, these psychic symptoms gradually disappeared. In the study of organic and symptomatic psychosis, Mackenzie and Popkin (1983) have proposed the concept of an organic anxiety syndrome on the ground that DSM-III provides no organic equivalent for anxiety disorders. Therefore, we presented a case of chronic subdural hematoma in which the direct effect on CNS of this pathological condition was considered to bring about the above-mentioned anxiety disorders with regression-like symptoms.
