thalamotomy

 [thal″ah-mot´ah-me]
a stereotaxic surgical technique for the discrete destruction of specific groups of cells within the thalamus, as to relieve pain, to alleviate tremor and rigidity in parkinson's disease, or to relieve certain anxiety states, psychoses, and obsessive-compulsive states.

thal·a·mot·o·my

(thal'ă-mot'ŏ-mē),
Destruction of a selected portion of the thalamus by stereotaxy for the relief of pain, involuntary movements, epilepsy, and, rarely, emotional disturbances; produces few, if any, neurologic deficits or undesirable personality changes.
[thalamus + G. tomē, incision]

thalamotomy

(thăl′ə-mŏt′ə-mē)
n. pl. thalamoto·mies
Surgical excision of a portion of the thalamus, usually to relieve tremor, as in Parkinson's disease.

thal·a·mot·o·my

(thal'ă-mot'ŏ-mē)
Destruction of a selected portion of the thalamus by stereotaxy for the relief of pain, involuntary movements, epilepsy, and, rarely, emotional disturbances.

Thalamotomy

A surgical procedure that destroys part of a large oval area of gray matter within the brain that acts as a relay center for nerve impulses. The thalamus is an essential part of the nerve pathway that controls intentional movement. By destroying tissue at a particular spot on the thalamus, the surgeon can interrupt the nerve signals that cause tremor.

Patient discussion about thalamotomy

Q. Should I go for the knife? I have essential tremor for many years, and in the last few years it seems nothing helps it, and although I tried all the drugs my doctor could offer me, nothing helps. It really ruins my life, and recently I read about a surgery that suppose to treat it, called thalamotomy- does anyone know anything about it?

A. It's a possibility, and considered effective (reducing tremor in most of the patients). However, it has quite serious side effects, that can result even in weakness of some parts of your body. You should think really good before you opt for this treatment. Good luck!
