Overview
Surgery
Surgical managament of few symptoms are as follows--
Trigeminal neuralgia
When drugs are not effective enough surgery may be recommended. Further damage to the nerve to prevent the transmission of pain (Rhyzotomy) has proven its efficacy;[1] however the beneficial effects and risks in multiple sclerosis patients of those procedures that consist in relieving the pressure on the nerve are still under discussion.[2][3]
Tremor and ataxia
If all these measures fail some patients are candidates for thalamus surgery. This kind of surgery can be both a thalamotomy or the implantation of a thalamic stimulator. Complications are frequent (30% in thalamotomy and 10% in deep brain stimulation) and include a worsening of ataxia, dysarthria and hemiparesis.
Thalamotomy is a more efficacious surgical treatment for intractable MS tremor, however the higher incidence of persistent neurological deficits in patients receiving lesional surgery supports the use of deep brain stimulation as the preferred surgical strategy.[4]
