[Atypical early posttraumatic syndromes (author's transl)].

In a consecutive series of 1,925 head injuries, 283 patients (14.7%), could not be classified, neither in the group of simple head injuries without cerebral symptoms, nor in the group of typical concussions characterized by immediate amnesia or observed coma. We have prefered the rather neutral term of atypical early posttraumatic syndromes. In this group, apart from neurovegetative manifestations, partial disturbances of consciousness and perception, we have also classified delayed disturbances of consciousness. Special attention has been given to migraineous phenomena and to a syndrome, characteristic for children, described by Mealey. This is an intermediate group important from a medico-legal point of view because certain transient cerebral manifestations risk to be mistaken for psychological reactions. On the other hand symptoms probably of psychic origin were discussed.
