On the basis of biomechanical principles, common head injuries can be classified into acceleration injuries characterised by a predominant diffuse cerebral injury and contact injuries characterised by a predominant focal injury. In a follow-up of 174 head injured patients, it was found that patients with acceleration injuries evinced a longer duration of coma, lengthier post-traumatic amnesia, and less number of skull fractures. Organic behaviour syndromes were seen mostly in acceleration injuries. During the prospective follow-up of 141 patients for a period of 18 months, there were differences in cognitive recovery. But, late behaviour changes and psychosocial outcome were not different in both groups.
根据生物力学原理，常见的头部损伤可分为以弥漫性脑损伤为主的加速性损伤和以局灶性损伤为主的接触性损伤。在对174例头部受伤患者的随访中发现，加速性损伤患者昏迷时间更长、创伤后遗忘期更长且颅骨骨折数量更少。器质性行为综合征多见于加速性损伤。在对141例患者进行为期18个月的前瞻性随访期间，认知恢复存在差异。但是，两组患者后期的行为变化和社会心理结局并无差异。
