Tardive dyskinesia (TD) is an involuntary movement disorder caused by long-term dopamine-blocking medications. Prolonged use may create chemical imbalances in brain areas controlling movement.

Stereotypic movement disorder is a motor disorder that develops in childhood, typically before grade school, and involves repetitive, purposeless movement. Examples of stereotypic movements include ...

Despite modern high-throughput sequencing, the genetic cause of most rare movement disorders remains unclear. A research team in Bochum and Tübingen has now solved one piece of the puzzle: The ...

Tic disorders are conditions featuring sudden, non-rhythmic movements or vocalizations. A formal tic disorder diagnosis is determined by tic frequency, duration, and type. Tics are non-rhythmic ...

Scientists at Brigham and Women's Hospital and Harvard Medical School have developed a targeted genetic test to improve diagnosis for X-linked dystonia-parkinsonism (XDP), a rare and disabling ...

A surprising discovery is overturning a long-held assumption about how the brain’s movement center works. Researchers found that two key cerebellar cell types—thought to be tightly linked—often don’t ...
