Uhthoff symptom(redirected from Uhthoff syndrome)
a transient temperature-dependent numbness, weakness, or loss of vision. Conduction stops in any nerve if the temperature becomes too elevated. In a damaged nerve, for example, by demyelinization, this shutdown temperature is lowered, and may approach normal body temperature. Transient neurologic dysfunction may then appear with a hot shower, exercise, or fever.
