A high incidence of asymptomatic neuromuscular disease was found. More than half showed EMG evidence of a `myopathy' and of denervation. The commonest syndrome was a neuromyopathy with myopathic units and spontaneous muscle activity, especially fasciculations and nerve fibre loss but with normal or near normal nerve conduction. This is thought to be the result of a neuronal or axonal disorder.
