[|Human|] my 53 year old brother is visiting for the Thanksgiving holiday. I am noticing fine motor tremors in his hands, and he tell me he has occasional spasticity in his arms, like a sudden jerking motion. I am worried and have told him he needs to see a neurologist. What could his symptoms represent?
[|AI|]  Hello, I have studied your case. There is possibility of nerve root irritation leading to muscle twitching. I will advise you to do MRI. There is possibility of parkinsonism. For these symptoms analgesic and neurotrophic [pregabalin] medication can be started. Another possibility of electrolyte disturbance leading to muscle twitch, I will advise doing detail blood investigation consulting your doctor. Till time, you can continue your medication. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
