The leading cause of extrapyramidal syndrome is psychiatric medication. Antipsychotic drugs and some drugs used to treat depression commonly cause extrapyramidal symptoms. Patients who take dopamine blockers can also develop this condition.
However, these symptoms can also occur in people with Schizophrenia who have never taken any of these medications [ref]. The four main types of extrapyramidal symptoms are Parkinsonian Symptoms, Dystonia, Akathisia, and Tardive Dyskinesia. See here for strategies on how to manage these symptoms.
