What causes TD?
TD is associated with taking certain kinds of crucial medications, such as antipsychotics, that help control dopamine, a chemical in the brain.
Antipsychotics are prescribed to treat conditions like:
- Bipolar disorder
- Schizoaffective disorder
Other medications used to treat upset stomach, nausea, and vomiting may also cause TD.
What does TD look like?
TD means having uncontrollable movements in one or more spots of your body.
TD is often seen in the lips, jaw, tongue, and eyes. It can also affect other parts of the body, including the upper body, arms, hands, legs, and feet.
TD can look or feel different from day to day.
Movements may appear:
- To be rapid and jerky, or slow and writhing
- In a repetitive, continuous, or random pattern

When can TD start?
Tardive dyskinesia (TD) symptoms may emerge after a few months of taking antipsychotic medications. In some cases, symptoms may not even start until after the medications are stopped.
In addition to taking antipsychotic medications, the following factors may also play a role in your risk for TD:
- Being 50 years of age or older
- Being postmenopausal
- Substance abuse
- Having a mood disorder
While working to control dopamine in one part of the brain, antipsychotic medications can make other parts of the brain more sensitive to dopamine, which may be associated with the movements of TD.
