Chronic Methylphenidate Effects on Brain Gene Expression: An Exploratory Review

Psychol Res Behav Manag. 2024 Feb 15:17:577-592. doi: 10.2147/PRBM.S445719. eCollection 2024.

Abstract

Methylphenidate (MP) is a psychostimulant commonly prescribed for individuals with attention deficit hyperactivity disorder (ADHD) but it is also taken with and without a prescription for performance enhancement. Prior research has characterized the effects of MP on behavior, cognition, and neurochemistry. This exploratory review covers the uses of MP and examined the effects of MP on gene expression in the brain following exposure. Overall, MP causes a wide-spread potentiation of genes, in a region-specific manner; consequently, inducing neuronal alterations, such as synaptic plasticity and transmission, resulting in observed behaviors and affects. Monoamine neurotransmitters and post-synaptic density protein genes generally had a potentiating effect in gene expression after exposure to MP.

Keywords: addiction; gene expression; methylphenidate; monoamine neurotransmitters postsynaptic density proteins; reward deficiency syndrome; substance abuse.
