My 17 son has hand tremors that we just noticed. They are worse when extending his arms, not so bad if he is holding something. He has a great uncle who had parkinsons.  Is parkinsons genetic? I will make an appointment for him tomorrow, but it seems very odd for an otherwise very healthy kid.
Hi, Thank you for posting your query. I have noted your sons symptoms. It is unusual to have symptoms of Parkinson's disease (PD) at a young age of 17. Also, the other features of PD such as slowness of activities and rigidity of arms/legs are not there, so, I do not think that your son has PD.PD can be genetic in about 10% of cases. Neurological examination would sort out the diagnosis. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly/
