This is an experimental avenue that awaits human trials.
Gabapentin is effective for both central or peripheral origin neuropathic pain, with an optimal daily dose of mg. Dejerine J, Roussy G.
Brain magnetic resonance imaging MRI of patients with this syndrome has shown infarctions, while single-photon emission computed tomography shows decreased dekerine flow, especially to the left thalamus.
