A case of young–onset Parkinson's disease who developed retrocollis with pain after four years after onset of symptoms

Abstract

A 38–year–old man with a family history of spinal and bulbar muscular atrophy and Parkinson's disease (PD) in his father and grandfather respectively, developed tremor and clumsiness of his left hand. His diagnosis was given as young–onset PD with resting and postural tremor, clumsiness and muscular rigidity of his left side. The patient developed neck extension (retrocollis) with pain when he had been treated with rotigotine and zonisamide, after 4 years from onset of parkinsonism. An analgesic patch was used for reducing the pain. There are various postural abnormalities known to be disabling complications of PD. Dystonia of foot is a common feature among patients with young–onset PD however, retrocollis is extremely rare. Consequently, attention should be paid to the presentation of retrocollis since both the pain and progession of postural abnormalities could influence the patient's quality of life.
