I am joining this group because my 74 year old mother has just been diagnosed with Parkinsons this year. My mom has my dad to help her daily and I am the only daughter that lives within close enough distance to assist on a regular basis. We are being seen by neurologist at Michigan State University and she is on Carbidopa and Carbidopa Levidopa. My biggest question has to do with how long does Parkinsons exist in ones body before the symptoms become detectable; my mom has had undiagnosed and unexplained nausea for approximately 10-11 years and no one seems to be able to diagnose. We have undergone every digestive test and scope / scan possible with no diagnosis including biopsies with negative results on all fronts. Does anyone else experience this with Parkinsons or not at all? Are there other drugs available for treatment of Parkinsons that do not cause severe nausea - she has tried taking with sweets, apple juice and plenty of water and nothing seems to help what is already a very tentative stomach/digestive situation - leaving her in bed for sometimes 4 out of 7 days a week....... looking for any straw
