There are certain diseases like Parkinson’s that can be cured with surgical techniques. These techniques can improve symptoms like hand tremor, lack of balance and other uncontrolled movements.

Surgical procedures like deep brain stimulation or thalamotomy are the most used in easing tremors. These procedures are performed only when the hand tremor is sever and all medication treatment had failed.

Deep brain stimulation or DBS is based on the implantations of electrodes in the part of the brain called the thalamus. The electrodes send high-frequency electrical impulses to the thalamus. The patient uses a magnet to turn on and off a pulse generator. The generator is implanted under the skin usually in the chest area. The batteries of the generator last for up to 5 years and can be replaced surgically. Deep brain stimulation is used to treat currently hand tremor and other forms of essential tremor. You should know that this procedure disabled the tremor temporarily and that it  is reversible by turning off the implanted electrodes.

Thelamotomy involves creating lesions in the thalamus and it is proven to be effective for patients with Parkinson’s, cerebeller tremor and essential tremor. During this procedure the patient’s head is stabilized in a metal frame and the neurosurgeon maps the brain in order to locate the thalamus. A hole is drilled into the skull and an electrode is inserted. Current is passed through to activate the tremor in order to confirm proper placement. After the site has been determined the electrode is heated to create a temporary lesion. After tests have been made and no problems had occurred the electrode is heated again this time on a permanent lesion.

The side effects of these kinds of surgical procedures include problems with motor control of speech. Problems with balance and even cognitive impairment like visual problems or learning difficulties.
