A 59‐year‐old man with severe neck extensor weakness had findings diagnostic of nemaline myopathy on muscle biopsy. Review of the literature shows that dropped head occurs in nearly half of the patients with adult‐onset nemaline myopathy. Other leading causes of dropped head syndrome are amyotrophic lateral sclerosis, myasthenia gravis, and isolated neck extensor myopathy. © 1999 John Wiley & Sons, Inc. Muscle Nerve 22: 1146–1150, 1999
