Abstract

Spinal and bulbar muscular atrophy and Parkinson's disease rarely coexist. We describe a male patient presenting with parkinsonism, hyposmia, with DAT-SPECT deficits, responsive to dopaminergic therapy, preceding recognition of SBMA confirmed genetically. Dopamine agonist–associated dropped head syndrome unmasked underlying lower motor neuronopathy, highlighting diagnostic pitfalls and overlap between synucleinopathy and polyglutamine disease.
