Hello, my dad was diagnosed with Parkinsons two years ago. He started on the medication shortly after. He is currently taking 1.5 pills four times a day but since the beginning we've never seen a dramatic response to him being on the meds vs off. He seems the same on the meds as opposed to off. Now drs are thinking he may have an atypical form of parkinsons and are increasing his doses to see if his response changes. But what is one suppose to feel or look like when its considered a "good" response. We dont know what to look for.
