Question: do you now what a essential tremor is if you do is there a cause for it?

Matt Dunn answered on 24 Jun 2016:

Essential tremors usually happen when you’re older (40-60) as parts of the brain that control movement break down, and the signals that control movement are either too many or too few, with no regulation. This means that there is ‘too much’ movement in the hand and also ‘not enough’, which can cause essential tremors, usually in the hands, which can affect writing, eating, and so on. SOmetimes the tremors spread to the rest of the body including the throat and mouth, making it hard to speak or eat.

If you know what areas of the brain have broken down, you can repair or replace the cells there, which should cure the tremor, and has been done in mice and rats 🙂
