A case of Devic's Syndrome presenting with tonic spasm: response to levetiracetam treatment
MetadataShow full item record
Neuromyelitis optica or Devic's syndrome is a rare autoimmune disorder which is characterized by inflammatory demyelination of the optic nerves and the spinal cord. Clinically, it causes visual loss in one or both eyes, and numbness or paralysis of the arms and legs. Although tonic spasm is the most frequent movement disorder occuring in MS, it has not been definetely described clinical entity for Devic's syndrome. We hereby describe a case of Devic's syndrome with tonic spasms treated with levetiracetam as a new approach and discussed the results of the treatment. A 52-year-old woman with Devic's syndrome with the complaint of painful tonic spasms primarily affecting the abdomen was given levetiracetam therapy. Levetiracetam therapy resulted in a good response in our patient. Levetiracetam can be a new choice for the treatment of painful tonic spasm with Devic's syndrome. However, more detailed studies are necessary to investigate efficacy of levetiracetam.
