Headache in schizophrenic patients: a controlled study.

Various studies have indicated that chronic schizophrenic patients share a lower rate of headaches than the normal population. A questionnaire concerning the symptomatology of headache was administered to 108 schizophrenic patients in the chronic stage and to 100 normal subjects. The questions dealt with type, location, frequency, severity, and duration of headache, as well as with its accompanying phenomena. Both groups shared a high distribution of headache reports, and generally no significant differences were observed in the various parameters. It was found that schizophrenic patients tend to refrain from complaining about their headache, although they are capable of its precise description. No correlation was found between the type of headache and type of schizophrenia.
