Medical Term:

Uhthoff symptom

Pronunciation: ut'hof


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, 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.

Synonym(s): Uhthoff syndrome
