 Division of Neuromuscular Disorders

Specialists in neuromuscular diseases possess specialized knowledge and skills in understanding, evaluating, and managing patients with disorders of the anterior horn cell, peripheral nerve, neuromuscular junction and muscles. This requires advanced knowledge of the pathology, pathophysiology, diagnosis and treatment of these disorders at a level more advanced than that acquired by a general neurologist. The need for such a specialized neurologist entails training neurology residents in the subspecialty of clinical neurophysiology at the level of a fellow in neurology.

Our Doctors accurately and effectively diagnose the diseases of patients by performing, interpreting, understanding and reporting electroencephalographies (EEG), nerve conduction studies (ENG), electromyographies (EMG) and evoked potential studies (EP). ​
