Extrapyramidal side effects are commonly associated with drugs that affect the dopamine system, particularly antipsychotics used to treat schizophrenia. These side effects can include symptoms similar to those seen in Parkinson's disease (e.g., tremors, rigidity) but do not mean the drug will produce Parkinson's disease itself. Instead, these side effects indicate the drug's effectiveness in reducing dopamine activity, which is associated with the reduction of positive symptoms (e.g., hallucinations, delusions) in schizophrenia. The fact that these side effects subside as the drug's effects wear off further supports the conclusion that the drug is acting on systems (dopaminergic pathways) relevant to schizophrenia treatment, rather than affecting the primary motor cortex directly or worsening schizophrenia symptoms.
