Gamma knife tremor patient comes back to get the other side done!

Our first tremor patient treated with gamma knife radiosurgery recently came back, one year later, to have the other side treated.
He has essential tremor, which was affecting both arms.
He had undergone treatment to the left brain for right sided tremor last year.
He was so pleased with his results, he recently came to have the right brain treated to address the left sided tremor.
Here is his most recent video.
Note the action and postural tremor on the left (untreated) side, and the fact that he has almost not residual tremor on the right (treated) side.

Deep Brain Stimulation for Essential Tremor

We have already blogged about “benign” essential tremor.

Here is a recap of the patient featured in one of those previous posts. He has a long history of worsening essential tremor, which has not responded to oral medications, and has made it impossible for him to hold a cup or write with a pen:

He decided to undergo deep brain stimulation, a procedure where tiny electrodes are placed into deep nuclei inside the brain. When these electrodes are activated, they cause an interruption in the brain circuits which cause tremor:

Here he is, after surgery, with the electrodes switched off:

Here he is with the electrodes to both sides of the brain switched on, see how much better his tremor is, particularly on the right side:

He can write and hold a cup for the first time in >10 years.

These same pathways can be inactivated by gamma knife radiosurgery in tremor patients who cannot undergo deep brain stimulation because of blood thinners, dementia or some other medical problem.
