The realization that your body isn’t responding as well as it used to can be frightening and make people feel insecure. This is true even with relatively small changes – such as regular vision loss. It can be especially scary when you find that in addition to your body not responding as you’re used to, you notice new symptoms, such as tremors. That feeling of concern can be compounded if you’re misdiagnosed. There are lots of diseases that have tremor as a symptom – of which the most well-known is Parkinson’s disease. In fact, it’s so well known that even if you have something known as essential tremor, there is a chance you’ll be misdiagnosed as having Parkinson’s. It’s important to know the difference between the two disorders because the prognosis is so very different.
