Parkinson's disease

Hi,
I am starting this thread so that people (Patients, their care takers, relatives and everyone else interested) can share valuable information related to symptoms, diagonosis and treatment of Parkinson's disease. Also, it'll be useful to know what can we do to prevent ourselves from this disease and who all are susceptible to this disease.
I would urge medical professionals, experts and specialists to share some valuable advice.
Thanks,
Raman Chhabra
