Isolated head tremor
Isolated head tremor is shaking of the head with no tremor anywhere else in the body and no signs of dystonia. It used to be labelled essential tremor, but because head tremor in essential tremor usually follows hand tremor, isolated head tremor is now regarded as a separate entity [1],[2]. It responds poorly to medication. In Prof. YILMAZ’s peer-reviewed series of 22 patients with rare tremor syndromes treated with double-target Vim+PSA DBS, the mean tremor reduction was 89% (range 50–100%), and 6 of 7 patients with isolated head tremor had a tremor score of 0 at 12 months, as rated blindly by two movement disorder specialists [2].
Key facts
- Isolated head tremor affects only the head, with no hand tremor and no dystonia.
- It is now classified as its own entity, not a form of essential tremor [1],[2].
- There is no reliably effective medication for it.
- In our published series, 6 of 7 patients reached a tremor score of 0 after double-target DBS [2].
- Both sides of the brain are always treated.
Who gets isolated head tremor
It typically begins in adulthood and progresses slowly. In our published series, the patients with isolated head tremor had had symptoms for at least four years, and none had tremor in other body parts or dystonic signs [2].
How it is diagnosed
The diagnosis is made when the head shakes and careful examination finds no hand, voice or leg tremor and no dystonia — no neck pulling, no null point and no sensory trick. Because dystonic and essential head tremor can look similar, video review by an experienced specialist matters. See diagnosis.
Why medication rarely works
There is no medication that works reliably for isolated head tremor. Botulinum toxin injections into the neck muscles can reduce the amplitude temporarily, but they must be repeated, and higher doses can weaken the neck or affect swallowing.
Why DBS works well here
The neck muscles are controlled by both sides of the brain, and it is difficult to tell which side drives a head tremor. For this reason we treat both sides. Using a trajectory that reaches both the Vim and the PSA gives the programmer more options to find the point that stops the tremor [2]. In our series, 6 of 7 patients reached a tremor score of 0; the seventh improved from 4 to 1 after an electrode had to be repositioned and later replaced because of infection [2].
