Dystonia is a movement disorder that can manifest as a complication from the use of antipsychotic medications. These drugs, especially the typical antipsychotics, are known to cause extrapyramidal side effects, which include various movement disorders like dystonia. Dystonia involves sustained muscle contractions, abnormal postures, and involuntary movements, and can occur shortly after the initiation of therapy or dose increases.

This side effect occurs due to the pharmacological effects of antipsychotics on dopamine pathways in the brain, particularly when there is a blockade of dopamine receptors. Understanding this association helps healthcare professionals in monitoring and managing patients on antipsychotic medications, ensuring timely intervention when symptoms arise. While other behavioral complications can occur with these medications, such as anxiety or exacerbation of existing mental health conditions, dystonia specifically is a notable neurological side effect directly linked to their use.
