[Prognostic significance of initial loss of consciousness in cerebrovascular disorders].

An initial loss of consciousness is of grave prognostic significance in patients with acute ischaemic cerebrovascular disorders, both as regards the early course as well as the long-term prognosis. The aim of this study was to assess the prognostic importance of an initial loss of consciousness in patients who had survived the acute stage. Thus, 133 out of 139 patients suffering from ischaemic cerebrovascular disorders who survived the first 3 weeks after a stroke were clinically re-examined after a mean follow-up period of more than two years. The other 6 patients had died as a result of a second stroke in the post-acute period. Patients with an initial loss of consciousness suffered cerebrovascular disturbances or fatal strokes in the follow-up period slightly more frequently than patients without an initial loss of consciousness. However, there were no convincing differences between the two groups. Indeed, on follow up, patients with an initial loss of consciousness were slightly less socially disabled than patients without an initial loss of consciousness. The results suggest that an initial loss of consciousness is no longer a factor of prognostic importance in patients who have survived the initial stage.
