Orthostatic dizziness is feeling dizzy or lightheaded when standing up. Hemodynamic orthostatic can be caused by autonomic dysfunction such as hypotension postural tachycardia syndrome. The interpretation of the function test results in patients with crucial for diagnosing and managing underlying condition. head-up tilt Valsalva tests are especially important evaluating adrenergic hemodynamic d...

Systemic estrogen administration in male rats has been shown to normalize the autonomic dysfunction and reduce the infarct size after permanent middle cerebral artery occlusion (MCAO). Therefore, the present investigation determined if local microinjection of estrogen at the site of the infarct also promoted recovery of autonomic function and reduction of the infarct size. Experiments were done...

The objective of this study was to investigate cardiovascular autonomic function in patients with parkin disease. Ten patients with a genetically confirmed diagnosis were compared to 11 healthy controls. Symptoms related to autonomic dysfunction were collected by structured interviews. Cardiovascular autonomic reflex function was evaluated using a standard battery of eight tests. Autonomic test...
