Just wondering if anybody else has another diagnosis that exacerbates your Parkinson's, and how you deal with it. About a year ago, what I thought was worsening PD symptoms actually turned out to be Bilateral Vestibular Hypofunction. From what I've read, BVH is even more rare than YOPD, about 28 out of 100k. Like PD, it is often idiopathic; that is the case of both diseases for me. Other shared traits: incurable, disabling, symptom variation, tempered by excercise, falling/balance issues.
