Answer:

Tardive dyskinesia

Explanation:

Tardive dyskinesia is a movement disorder characterized by uncontrolled facial movements, repetetitive tongue movements, chewing and sucking motions. It is caused by long-term use of neuroleptic drugs such as those that increase the brain's sensitivity to the neurotransmitter dopamine.  Decreasing the dosage or discontinuing the medication causing this dissorder may solve the patient problems or may worsen the symptoms.

There are several types of treatments for this dissorder such as changing medications or introducing new ones to the patient such as Ingrezza, Austedo, Botox, Clorazil or Klonopin but since some of this medications are know to cause Tardive dyskinesia as well, the patient's treatment must be adequated to his case.
