Dear Yen, Your father has been diagnosed with PD for five years, yet is only taking 300 mg of levodopa daily. It's possible that he is undermedicated. It's also possible that the "passing out" episodes are due to orthostatic hypotension, which can occur with PD medications. Is his physician a neurologist specializing in movement disorders? That is extremely important for his well-being as PD advances. As PD progresses, it becomes increasingly harder to prescribe exactly the right medications in the right amounts. I suggest you might e-mail your question to Dr. Abe Lieberman, a leading neurologist specializing in Parkinson's disease. If you'd like to do so, go to the NPF website: http://www.parkinson.org/ scroll down the page and click on Ask Dr. Lieberman, NPF Medical Director Follow the directions, and you'll be able to e-mail Dr. Lieberman directly. He usually responds within 48 hours. My very best regards, Kathrynne yen dinh wrote: > > Hi everyone, > > My father is 64 years old. He was diagnosed at 59.
