Abstract
A case of spinal muscular atrophy associated with myasthenic symptoms was reported. Clinical, pharmacological and electromyographic examinations on this patient were carried out. The study revealed different findings from classical myasthenia gravis and Eaton-Lambert syndrome. Discussion on the mechanism of symptomatic myasthenia with a special reference to the presence of significant defect of conduction in patients with diseases affecting the lower motor neurons was made.
