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.
Another potential cause of extrapyramidal syndrome is an injury to the brain that involves the extrapyramidal tract. Some forms of cerebral palsy can involve this area of the brain, and it can also be damaged by lesions from brain tumors and degenerative neurological diseases.
