Background: Lightheadedness on standing is a disabling symptom in Parkinson's disease associated with orthostatic hypotension and is thought to represent cardiovascular autonomic dysfunction. Traditional orthostatic blood pressures are normal in some patients with lightheadedness and other measures of cardiovascular dysautonomia can be insensitive. In this study, we used continuous non-invasive arterial pressure monitoring to measure beat-to-beat changes in blood pressure and heart rate on standing and during Valsalva as a potential marker of autonomic dysfunction.

Additionally, drug-induced Parkinsonism may, in some cases, represent "unmasking" of incipient Parkinson's disease. Clinical features or tests that distinguish degenerative from pharmacologic Parkinsonism are needed.

Purpose: To investigate the effects of social support among patients with HF, we examined whether aspects of social support were associated with self-care, including medication adherence, dietary adherence, and HF symptom monitoring functions.
Methods: We recruited 74 patients with HF from cardiology clinics of a Veterans Affairs Medical Center and a university-affiliated hospital, and tested the relationships between social support and the patients' self-care.
