## Postprandial hypotension and parkinsonian state in Parkinson's disease.

Chaudhuri KR, et al. Mov Disord. 1997.


Abnormal postprandial cardiovascular responses such as postprandial hypotension (PPH) occur in primary autonomic failure and contribute significantly to morbidity. The extent and frequency of PPH and its relationship to the parkinsonian state in idiopathic Parkinson's disease (IPD) is unknown.

By studying 20 patients with IPD (without autonomic failure) and 16 age-matched controls after both groups ingested a standard isocaloric balanced liquid meal, we have shown that supine PPH complicates IPD and is related to marked worsening of the parkinsonian state as measured by a cumulative score of tremor, rigidity, bradykinesia, posture, and gait.

Furthermore, significant postural hypotension is unmasked that results in postural intolerance due to presyncopal symptoms.

Our study indicates that, in patients with IPD, ingestion of a meal may lead to abnormal postprandial cardiovascular responses and aggravation of the parkinsonian stage. The underlying mechanisms are unclear, although vasodilatory gut peptides released in response to food ingestion may be contributory.

Postprandial hypotension.

Postprandial hypotension is both common in geriatric patients and an important but under-recognized cause of syncope. Other populations at risk include those with Parkinson disease and autonomic failure...
