[ 1 ] - Hyperprolactinemia and CYP2D6, DRD2 and HTR2C genes polymorphism in patients with schizophrenia

Introduction: Hyperprolactinemia is a common serious side effect of antipsychotic medications that are currently used in the treatment of patients with schizophrenia. Pharmacogenetic approaches offer the possibility of identifying patient-specific biomarkers for predicting the risk of this side effect. We investigated a possible relationship between variants (SNPs) in genes for cytochrome 2D6 (...

[ 2 ] - Dissimilar mechanistic background of peripheral and orofacial hyperkinesia in patients with Parkinson’s disease and levodopa-induced dyskinesia

Introduction: Long-term levodopa treatment of Parkinson’s disease (PD) is frequently complicated by spontaneously occurring involuntary muscle movements called dyskinesia. The exact pathological mechanism of this complication has not yet been elucidated. We have previously demonstrated that in PD patients the vulnerability to develop peripheral but not orofacial dyskinesia is associated w...
