Tardive dyskinesia (TD) is a neurological disorder characterized by involuntary, repetitive movements of the face, limbs, or torso. These movements can be distressing and can significantly impact a person’s quality of life.

Symptoms of Tardive Dyskinesia
The symptoms of TD can vary in severity and may include:
Involuntary movements
These movements often involve the face, such as grimacing, tongue protrusion, or lip smacking. They can also affect the limbs and torso, leading to twitching or jerking motions.
