My name is Daniel Myers and I am a first year medical student. I am currently doing extra-curricular research on Parkinson\'s Disease but much to my dismay, am unable to find very much information on the mental and phsycological effects of PD. Do sufferers commonly experience symptoms of dementia, depression, confusion etc or are symptoms largely limited to physical movement? I would sincerely appreciate any reply from sufferers, carers or indeed anyone with experience in PD. Please forgive me for my ignorance. - Daniel
