My dad is 81 yrs old and has been diagnosed with PD for years now, over 10. Until recently, his disease has been very manageable. He needs help getting dressed and is mostly extremely tired and slow. He doesn't walk well but can still manage to get around with a walker. But in the last few weeks he has developed vertigo which has caused him to loose 3 out of 5 meals. Is vertigo part of PD? Also, my mom, his caretaker, is wondering what to expect next. Is this the beginning of the end?View Thread
