Persistent akathisia associated with early tardive dyskinesia

Area of Science:

• Psychiatry
• Neuroscience
• Pharmacology

Background:

• Antipsychotic medications are crucial for managing psychiatric disorders.
• Tardive dyskinesia (TD) is a potential side effect of long-term antipsychotic use.
• Akathisia is a common, often distressing, side effect characterized by a feeling of inner restlessness.

Observation:

• Two young psychiatric patients developed moderate to severe oro-facial and limb dyskinesia.
• These movement disorders appeared within one year of initiating antipsychotic drug treatment.
• Both patients experienced persistent akathisia early in treatment, which continued despite dose reductions.

Findings:

• The early onset of tardive dyskinesia was observed in these patients.
• Persistent akathisia preceded the development of tardive dyskinesia.
• The emergence of TD occurred despite maintenance-level doses of antipsychotic medication.

Implications:

• Persistent akathisia may serve as an early warning sign for the development of tardive dyskinesia.
• Clinicians should be vigilant for akathisia in patients on antipsychotics, especially younger individuals.
• Early recognition and management of akathisia could potentially mitigate the risk or severity of tardive dyskinesia.
