We report the first detailed study of the neurological, electromyographic, and muscle biopsy findings in patients with hyperparathyroidism.
Over 80% of our 16 patients presented with a distinct syndrome consisting of easy fatigability; weakness and atrophy of proximal muscles, particularly of the leg; tongue tremors; and normal or hyperactive reflexes. The presence or severity of weakness bore no relationship to the alteration of any serum ion measured, including calcium. The electromyograms showed short-duration, low-amplitude complex and, sometimes, polyphasic potentials mingled with high-amplitude, long-duration motor units. Motor and sensory nerve conduction times were normal. Muscle biopsies showed neurogenic atrophy of both
