Hi, I have a cousin who has essential tremors. He is 60 years old and has had the condition since age 16, though in recent years it has become disabling. His voice sounds very irregular over the phone, he says that his shaking is out of control, and he can no longer walk. He lives with a friend and has a caretaker a few hours each day, thankfully, but He cannot hold down a job. Have you heard of essential tremors keeping someone from being able to walk? Thank you!
