Which disorder spans 6 or more months with akathisia, dystonia, oral-buccal-lingual dyskinesia, tics, tremor, and stereotypies?

This item tests tardive dyskinesia, a late-onset, persistent movement disorder that arises after long-term dopamine receptor blockade from antipsychotic medications. The described cluster—akathisia (restlessness), dystonia (sustained muscle contractions), oral-buccal-lingual dyskinesia (lip-smacking, tongue movements), tics, tremor, and stereotypies—together persisting for six months or more, matches tardive dyskinesia, which requires a duration of six months or longer and can involve a wide range of involuntary movements across the face, mouth, limbs, and trunk. Acute dyskinesias occur soon after starting antipsychotics and are typically shorter in duration, so they don’t fit the six-month criterion. Tourette disorder features motor and vocal tics that begin in childhood and are not specifically tied to long-term antipsychotic exposure or this broad, persistent dyskinetic pattern. Spasmodic torticollis (cervical dystonia) is a focal dystonia of the neck, not the widespread orofacial and other involuntary movements described here, and it doesn’t meet the duration criterion in this context.
