Which term describes the symptoms of involuntary facial grimaces and unusual lip movements due to medication use?

The term that describes the symptoms of involuntary facial grimaces and unusual lip movements due to medication use is known as tardive dyskinesia. This condition is often a side effect of long-term use of antipsychotic medications and is characterized by repetitive, involuntary movements, particularly of the face, lips, and tongue.

Tardive dyskinesia can arise after prolonged exposure to dopamine receptor antagonists, which are commonly found in medications for psychiatric disorders. Understanding this condition is crucial for professionals in music therapy and other therapeutic practices, as clients may experience these effects, which can influence both their participation in therapy and the methods that therapists may use to engage them effectively.

The other terms do not relate to the involuntary movements described in the question. Neuropathic pain refers to pain caused by nerve damage, akathisia involves a state of agitation or restlessness, and cognitive dissonance pertains to the mental discomfort experienced when holding contradictory beliefs or attitudes.
