What are the extrapyramidal symptoms associated with antipsychotics primarily characterized by?

Extrapyramidal symptoms (EPS) associated with antipsychotics are primarily characterized by neurological issues. These symptoms arise due to the impact of these medications on the dopaminergic pathways in the brain, particularly those that regulate motor control such as the extrapyramidal system. Patients may experience a range of symptoms including tremors, rigidity, bradykinesia, and tardive dyskinesia, all of which are linked to disruptions in normal motor function.

In contrast, skin rashes, gastrointestinal disturbances, and respiratory problems do not define the neurological dysfunctions caused by antipsychotics; rather, they may be related to other class-related side effects or adverse reactions of these medications. Thus, the focus on neurological issues in the context of EPS accurately reflects the main characteristic of these symptoms related to antipsychotic treatment.
