fees, those with workman's compensation injury (51 %n) easily develops to a post-traumatic case. Fees partly paid e.g. nation insurance (9%) is rather rare, while those with no fees e.g. health insurance (17%) and automobile accident indemnity (12%) comprises the remaining cases. Troublesome is the patient who visit a doctor with many complaints for a long period without any corresponding findings. In respect to numbers of complaint and consultation time (usually visit fortunightly) of post-traumatic cases, there is no significant difference among ARAKI's classification on head injury in acute stage, however, there is an obvious difference between the injured and the wounded in the same type of injury. In thos under twenty years of age, there is little difference between the injured and the wounded, though, in adults, the wounded complained two times more than the injured and five times as much in the consulted time. On the electroencephalographic finding in 253 cases (75% of the posttraumatics), 37% was abnormal in the injured. On the other hand, 21% was abnormal in the wounded. Above evidence indicate that psychologic factors have a great significance on the course and complaints. Such factors are dependency as a victim who is suspending compensation, hostility toward the person responsible for the injury, and anxiety on his condition of head injury.
