Wilson's disease presenting with an unusual cough



A 26-year-old man developed an unusual repetitive, nonproductive cough. Extensive pulmonary and otolaryngology investigations failed to disclose a cause. It was only after he developed additional neurological manifestations ultimately leading to the diagnosis of Wilson's disease (WD) that a neurological basis for the cough was suspected. Features of the cough suggest it was a form of respiratory dyskinesia, a previously unreported presentation of WD. © 2005 Movement Disorder Society
