Blood pressure and heart rate variability were analyzed in eight patients with progressive supranuclear palsy in comparison with two control groups (10 healthy patients and 10 patients with multiple system atrophy). Blood pressure and heart rate were recorded using digital photoplethysmography with the patient in supine position and during a head-up-tilt test (70 degrees for 10 minutes). Spectral analysis was performed using fast Fourier transformation for 512 consecutive systolic blood pressure and heart rate values. The head-up-tilt test induced a significant increase in systolic blood pressure in patients with progressive supranuclear palsy and in healthy patients and a significant systolic blood pressure decrease in patients with multiple system atrophy. During the head-up-tilt test, low-frequency energy of systolic blood pressure (70-130 mHz) that reflected baroreflex-dependent sympathetic tone also increased in patients with progressive supranuclear palsy and in healthy patients. By contrast, in patients with multiple system atrophy, the low-frequency energy of systolic blood pressure decreased significantly. The changes observed in the low-frequency band and the high-frequency band of heart rate (reflecting parasympathetic drive to the heart) were not different among the three groups. These data show the lack of impairment in autonomic nervous system activity in patients with progressive supranuclear palsy.

D001341 Autonomic Nervous System The ENTERIC NERVOUS SYSTEM; PARASYMPATHETIC NERVOUS SYSTEM; and SYMPATHETIC NERVOUS SYSTEM taken together. Generally speaking, the autonomic nervous system regulates the internal environment during both peaceful activity and physical or emotional stress. Autonomic activity is controlled and integrated by the CENTRAL NERVOUS SYSTEM, especially the HYPOTHALAMUS and the SOLITARY NUCLEUS, which receive information relayed from VISCERAL AFFERENTS.
