Schizophrenia is a complex illness that may partly involve your genes. But other events in your life may also play a role.
Scientists are edging closer to figuring out if there are ways to lower the risk of schizophrenia.
Not everyone who takes medicine to treat a mental health problem will get TD. If you do have unusual movements, your doctor can lower the dose or switch you to a different drug to relieve your symptoms.
They work by blocking a brain chemical called dopamine. It helps cells talk to each other and makes the muscles move smoothly. When you have too little of it, your movements can become jerky and out of control.
You can get TD if you take an antipsychotic drug, usually for 3 months or more. But there've been rare cases of it after a single dose of an antipsychotic medicine. Older drugs called "typical antipsychotics" are more likely to cause these movements than newer "atypical" ones. Some studies find a similar risk between both types, though.
