[Electromyographic signs of neurogenic involvement in hypokalemic paralysis as a result of diuretic abuse].

A female is reported, which showed motor and sensory disturbances following severe hypokalemia induced by abuse of diuretics. Elevated CSF-protein and abnormal neurographic findings with restitution after substitution with potassium led to the diagnosis of a neurogenic involvement like a Guillain-Barré syndrome. In the literature similar cases are described. So it seems, that beside of myopathic changes neurogenic disturbances can appear as a neurological symptom of hypokalemia.
