[EEG after so-called whiplash injury of cervical vertebral column (cervicocephalic acceleration trauma)]

The results of electroencephalographic examinations made on four groups of patients are compared. These groups include 80 patients with cervicocephalic syndromes due to flinging injuries to the cervical vertebral column, 80 patients with postconcussive syndromes, and 39 patients whose anamneses suggested conditions resulting from the two kinds of injury referred to above. A fourth group of 40 patients with nontraumatic spondylosis deformans cervicalis is compared with the first three groups of patients. The rate (49 percent, 52 percent, and 54 percent), kind, and distribution of electroencephalographically determined abnormalities are in agreement with those obtained for the first three groups. For patients with nontraumatic cervicocephalic syndromes the rate of general alterations determined from records obtained by means of the electroencephalograph is equal to the occurrence of constitutional EEG variants, the rate being of the order of 10 percent. EEG alterations observed in the case of flinging traumata are considered to de due to acceleration injuries to the cranial contents.
