The Causality Spectrum of Dropped Head Syndrome is Broad and Includes Myopathy, Neurodegenerative Disorders, and Varia.

Dropped head syndrome is a common complication of various neurological disorders. Most commonly, dropped head syndrome is due to primary or secondary myopathy. However, neurodegenerative diseases and various other conditions can also be complicated by dropped head syndrome. Among the primary myopathies, dropped head occurs most commonly in association with mitochondrial disorders, congenital myasthenic syndrome, and axial myopathies. Among the secondary myopathies, dropped occurs most commonly in association with inflammatory myopathies. Myasthenia is the most common transmission disorder associated with dropped head syndrome. The neurodegenerative disorder most commonly associated with dropped head syndrome is Parkinson syndrome. The diagnosis and treatment of dropped head syndrome from any cause requires a multidisciplinary approach. Outcome varies considerably but early diagnosis and early treatment are associated with a more favourable outcome.
