Brief Summary:
The objective of this experiment is
Primary To determine the effects of tyrosine supplementation on orthostatic hypotension in people with PD
Secondary To determine the effects of tyrosine supplementation in people with PD with autonomic insufficiency on HR BP and norepinephrine responses during acute exercise stress
Orthostatic hypotension and autonomic abnormalities are a common problem for individuals who suffer from PD especially as it leads to lightheadedness and falling For those affected it can drastically reduce quality of life It has been hypothesized that tyrosine may impact upon individuals suffering from PD There is ample evidence in animal models that supports our theory however there is no clinical evidence of the impact tyrosine supplementation may have in PD patients who suffer from orthostatic hypotension and blunted BP and HR responses Positive findings that supplemental tyrosine increases BP and HR in people with PD during daily activities such as standing up from a chair and walking can lead to new therapies to improve Parkinsonian orthostatic hypotension
Hypothesis We will test the hypothesis that symptomatic individuals with PD on dopamine therapy who suffer from orthostatic hypotension and blunted HR and BP responses will improve after tyrosine supplementation
