INTRODUCTION: Head-drop is often encountered in myasthenia gravis (MG) patients, but its frequency and clinical course have not been studied systematically.
METHODS: In a retrospective study of a cohort of MG patients seen over a period of 11 years in a tertiary medical center, we assessed the clinical characteristics of patients who had head-drop.
RESULTS: Of 146 generalized MG patients, 15 had head-drop during the course of their disease. Head-drop patients had older age of onset than those who did not have head-drop (mean age of onset 59.1 vs. 42.3 years) and were predominantly men. Head-drop was present in 23% of patients > 60 versus 6% of those < 60 years, and it improved in 9 of 11 patients with treatment directed to generalized MG.
CONCLUSIONS: Head-drop is a common, treatment-responsive manifestation of late-onset MG. Muscle Nerve 56: 441-444, 2017.
