I am in the process of reading the actual study for the recent CoQ10 test. Some interesting things so far: People were excluded from the study for the following reasons: 1. "The use of drugs known to interfere with mitochondrial activity." I would like to avoid these all the time--how do we find out drugs on this list? 2. "The use of methylphenidate hydrochloride, cinnarizine, reserpine, amphetamines, or monoamine oxidase-A inhibitors within 6 months before the baseline visit." I havent done my research yet to determine if this restriction is for positive or negative reasons i.e. could influence outcome of the subject patient in a positive or negative manner. 3. "An unstable dosage of drugs active in the central nervous system (e.g. anxiolytics, hypnotics, benzodiazepines, and anti-depressants) during the 60 days before the baseline visit." HOw would this impact the outcome of experiment? Another interesting point: "The wafers with active study drug contained 300 mg of coenzyme Q10 and 300 IU of vitamin E as a lipophilic carrier" Hmmmmm--i dont remember this coming up in the discussion earlier. I dont think the Vitaline CoQ10 wafers contain any vitamin E! Also: "Patients were asked to take a standard daily multivitamin without minerals but no other supplemental vitamins." And finally: "A blood sample was again drawn at the final visit for evaluation of platelet mitochondrial function." Could a simple blood test be used to help diagnose PD?
