Great cure but we lost the patient
The Journal of Neuroscience has a surprising case report of a patient who was treated with an implanted brain stimulator to treat severe movement side-effects from an extended period of taking antipsychotic drugs for behavioural problems.
This is the background to the case:
A 27-year-old woman with developmental delay and severe behavioural disturbance was treated with risperidone 6 mg/day from age 14. At age 20, she developed facial twitching, blinks, and truncal extension spasms, which persisted during both sitting and lying supine. By age 21, she was no longer able to walk due to the spasms. She became housebound and was forced to ambulate by crawling, to the extent that she developed post-traumatic cysts over both knees. She was unable to sit in a chair. She was forced to eat from a plate on the floor while kneeling because the extension spasms were too severe in other positions.
