Studies on the head injuries of human subjects in advanced age. I.

A variety of traumata of central nervous system was caused in the wake of the First World War. Of these traumata, greater emphasis was laid upon head injury in view of its direct connection with death, and a number of therapies have been developed to this end. In the later period, a new type1 of head injury caused by traffic accidents have increased in addition to the head injury caused by war incidents; it has grown up to share the majority of all the traumata caused by traffic accidents. A recent report describes that it shares as much as 70% thereof many countries 2,3 Japan cannot be the exception of this trend. However, few reports have been so far published on the head injuries in aged people, particularly those in highly advanced age, who have specificity in their physiology and pathology. In this report, we have conducted statistical observa tion on the clinical aspects (causes of traumata, duration of unconsciousness, and subjective and objective symptoms) and on the results of their treatments with accessory diagnostic aids.
