<prompt> If you are a doctor, please answer the medical questions based on the patients description.I work with a you young man age 17 at a restaurant he is a dishwasher,,, and he has broken so many dishes that worries me that he may have signs of a bigger problem,,, he says he doesn t understand why he does this,,, its in his hand one moment and out the next  <response>: I read your question carefully, and I understand your concern. If he has weakness during other activities as well it could well be the case of neuromuscular disease, a peripheral neuropathy or myopathy. In order to make such a diagnosis though a neurological exam is essential as there can be many such conditions with variable manifestations and causes, its not an easy straightforward diagnosis.Also, tests might be needed like nerve conduction studieselectromyography and some blood lab tests. I hope to have been of help.
