One word of advice for you is you can't diagnose Parkinson's properly when you think you already have Parkinson's. Your body will mimic Parkinson's like symptoms once the thought and fear of Parkinson's enters your mind. Parkinson's is best diagnosed when you don't believe you have Parkinson's and only your doctor think you have Parkinson's. Also, if you still have your sense of smell, I.e you can smell a banana or coffee, I would rule out Parkinson's myself and live your life until your sense of smell is completely gone. This is the easiest way to rule out Parkinson's. Tremors and other PD symptoms usually appear years after losing smell which is one of the prime early indicators of PD. Your prescription meds might also be partly to blame so try to wean them off and try something herbal and natural. There is absolutely no benefit in diagnosing Parkinson's early. It will make your health insurance premiums go up, life insurance rates to go up, change family dynamic wit your spouse,kids, friends and family. So please do your self a favor and stop chasing Parkinson's if you can still smell a banana, coffee, even a little. Worry about Parkinson's after you can't smell anything at all. Do regular exercise. Keep stress levels down. Tripala, shayankapushpi, Ashwaghnda are good herbs to try regardless if if you have PD or not. They are healthy on brain cells. Remember, there is absolutely no benefit in diagnosing Parkinson's early.
