[The epidemiology of postconcussional hypotension].

The presentation deals with a study of 942 patients (males and females from 16-68 years of age) with sequelae of brain damage, checked up with the duration of the post-traumatic period from several months to 35 years. The author draws special attention to the influence of sex, age and the duration of the posttraumatical period on the frequency of postconcussional hypotension. The obtained results point to a high frequency of postconcussional hypotension in the different age and sex groups compared to that found in the general population in screening. The prevalence of hypotension among females was higher. With an increase of the postconcussional period in males there was a tendency towards an increase of hypotension.
