Orthostatic hypotension following acute intracerebral haemorrhage.

BACKGROUND Blood pressure regulation may be impaired following acute stroke. Typically, there is overactivity of the sympathetic nervous system and underactivity of the parasympathetic system resulting in transient hypertension. Orthostatic hypotensive responses in acute stroke are less well documented. CASE REPORT We present a case of severe persistent orthostatic hypotension (OH) following acute intracerebral haemorrhage in a previously fit and well man. Symptomatic OH persisted for 60 days post-stroke. No known causes of OH could be identified. CONCLUSIONS Such profound and persistent orthostatic hypotension following an acute intracerebral haemorrhage has not previously been documented. The precise cause of this finding in the case described is unknown, but may have been due to impaired higher-level regulation of the autonomic nervous system. A conservative approach with prolonged physical methods proved successful in rehabilitating this patient without the need for pharmacological intervention.
