A video from the Depression and Bipolar Support Alliance discusses information about tardive dyskinesia (TD), as well as how the nervous system works. Some people do not have enough, too much, or irregular neurotransmitters to bind to receptors that can cause irregular signaling, possibly explaining the symptoms of mental health conditions including schizophrenia, bipolar disorder, and depression. In order to treat mental health conditions, antipsychotics are often given, and much of these therapies are dopamine-receptor blocking agents. More signaling can occur when dopamine is binding to hypersensitive dopamine receptors, having an impact on areas of the brain that impact motor function, causing TD.
