Neurology: Case of the Month

History and Physical — Patient 88

History

Present Illness: A 35 year old right-handed, previously neurologically normal gentleman presented in with new onset symptoms of increasing nervousness and restlessness. He was seen by a psychiatrist, diagnosed with an anxiety disorder, and started on buspirone without any noticeable benefit. Soon thereafter, he reported akathisia along with intermittent focal dystonia of his left hand and torsional dystonia of his left upper arm for which he was treated with different combinations of benzodiazepines, diphenhydramine, and atypical antipsychotics. Five months later, he reported frequent episodes of inversion to his right foot associated with cramping and a change in his gait. He continued treatment for possible extrapyramidal symptoms and achieved limited relief with benztropine. However, by about one year after presentation, his left leg became contorted. Two months thereafter, he demonstrated generalized dystonia with prominent oromandibular features.

He continued medical treatment without success and was eventually placed in a behavioral health center after a tertiary medical facility diagnosed him with conversion disorder. By the time he was seen again by neurology, he was admitted to a psychiatry ward for uncontrolled pain from his neck torticollis along with frequent panic attacks.

During this progressive decline, he denied sensory changes, fatigability, fasciculations, muscle atrophy, visual/auditory changes, or cognitive decline.
