The sleep-related respiratory and blood pressure changes in a patient with Shy-Drager syndrome associated with the sleep apnoea syndrome are reported. Polygraphic recordings showed repeated apnoeic episodes during both sleep and wakefulness. Systemic arterial pressure values during sleep tended to be lower than in two other patients with Shy-Drager syndrome, and, unlike observations in the sleep apnoea syndrome, nocturnal swings of arterial pressure related to obstructive apnoea were markedly reduced. As a result, the total sleep time was reduced; a sleep with several features similar to REM stage was identified; during this stage the arterial pressure reached the lowest levels recorded. A review of the literature revealed that nocturnal respiratory disturbances were detectable in a high percentage of patients with Shy-Drager syndrome. We suggest that such an association is not a chance one.
