Extrapyramidal symptoms (EPS) are drug-induced movement disorders that can occur as side effects of certain medications, particularly antipsychotics. These symptoms include tremors, rigidity, bradykinesia (slowness of movement), and abnormal postures. EPS can significantly impact a person's daily life and may require additional treatment.
The term "extrapyramidal" refers to the neural pathways outside the pyramidal tracts, which are involved in voluntary movement. Medications that block dopamine receptors in the brain, such as antipsychotics, can disrupt normal motor function, leading to these symptoms. Management may involve adjusting medication or using specific treatments to alleviate the symptoms.
