Jamaican neuropathy: an electrophysiological study

Jamaican neuropathy (JN) is a common disorder in Jamaica and has characteristics similar to neurological diseases found in other tropical areas. JN is a clinical syndrome and occurs in two forms: spastic and ataxic. This is the first known electrophysiological study of this disease. In the spastic group of JN, peripheral electrophysiological findings were mostly normal, suggesting a central cause for their symptoms. The only patient with the ataxic form of JN had a chronic axonal peripheral neuropathy.
