Hello @agodjali2008 and welcome to Mayo Clinic Connect. I'm pleased that you are advocating for your uncle. In our complicated health system, it is important to have someone by our side.
As you may know, Mayo Connect is a patient support network. We are not medical professionals but patients who share their experiences and offer support and encouragement therefore we cannot offer diagnoses,
That being said, there are many reasons why people have tremors. Here are some links to discussions here on Connect where members have discussed tremors:
https://connect.mayoclinic.org/discussion/orthostatic-tremors/
https://connect.mayoclinic.org/discussion/hand-tremors/
https://connect.mayoclinic.org/discussion/functional-tremors/
You do not mention if your uncle has any other health problems or symptoms other than tremors. For example, does he have problems with balance, walking, heart problems, vision problems, etc.? Certain medications can cause trembling or tremors. Also, we have many members who were exposed to Agent Orange and have resulting Parkinson's or a tremor disorder. Was your uncle exposed to Agent Orange in the military?
From your post, you do not mention that he has talked with a doctor about these tremors. Is that a correct assumption? If that is the case, it is important that he report this to his primary care physician who might give him a referral to a neurologist.
I hope some of this is helpful to you. I hope that you will post again and let me know how you are doing in coming up with a diagnosis. Will you check out the discussions listed in this post and let me know if anything is helpful to you?
Hello Teresa, thank you for taking the time to response to my question. I have read through the links that you provided, but none of them seems to fit my uncle’s condition.
My uncle is healthy in general, no other medical condition other than the ones I described. He is also not on any medication currently, except for some vitamins. No exposure to Agent Orange either.
We have seen several neurologists. The first one suspected Parkinson, so my uncle was put on Levodopa, but no sign of improvement after taking the drug for some time, so later the doctor concluded that the initial Parkinson diagnose could be wrong. We also did brain MRI, nothing abnormal was detected.
We went to another doctor, was prescribed Diazepam, but also no effect.
Other doctor only suggested brain vitamins, like BrainAct. The only explanation from the doctor is that it’s a disease associated with old age.
