Unconscious state at the time of injury was observed in 128 cases and 72 cases showed fracture of the skull. Posttraumatic disturbances were observed in 117 cases.
Headache was a closely related with weather, temperature, atmospheric pressure, etc. C.S.F. pressure was higher in cases which showed posttraumatic disorders of focal signs. Disturbance of C.S.F. absorption was observed in a half of cases which were examined. Pneumoencephalography was performed 135 times in 100 cases, and 81 cases showed abnormalities, i.e., ventricular dilatation, insufficient or no air insufulation of air into the ventricles, indistinct shadow of the cerebral cortex,etc.
Posttraumatic disorders were more frequently observed in cases in which blood was detected in C.S.F. at the time of injury. The bleeding causes disturbance of C.S.F. absorption and increase in C.S.F. pressure. Indistinct shadow of the cerebral cortex was also observed in such bleeding cases in which result of treatment against headache was also remarkable.
Narrowing of visual fiield was observed in 24 of 66 cases which were examined. Posttraumatic epilepsy was observed in 13.6%.
As for the treatment, depressed fracture of the skull was treated surgically and pneumoencephalography, physical treatment, exercise, etc. were effective. In cases of blunt injury insufficient filling of air by pneumoencephalography, narrowing of visual field and posttraumatic neurosis were more frequentiy observed than in cases of shoot wound, and posttraumatic epilepsy was less than the latter cases.
