Antecedent events in motor neuron disease.

Abstract

Sixty-three patients with motor neuron disease and sixty-one controls matched for age and sex were interviewed concerning life events. An antecedent history of back injuries was found more often and there was an increased incidence of prior electric shock amongst the patients. No increase of head injuries, fractures, malignancy or previous poliomyelitis was detected.
