Project description:Attention deficit hyperactivity disorder (ADHD) is a common psychiatric condition of children with a prevalence of 5-10% worldwide. Up to 30% of adults with a history of childhood ADHD maintain symptoms in later life; these adult ADHD patients are severely impaired in social and professional life due to persistence of ADHD core symptoms like impulsivity, attention deficit and hyperactivity as well as frequently observed co-morbidities like alcohol and drug abuse, major depression, bipolar and personality disorders. Pharmaceutical treatment options include methylphenidate (MPH), which is amongst others an inhibitor of the dopamine transporter and therefore increases dopamine levels in the brain. However, not all ADHD patients are MPH responders with clinical features to distinguish responders and non-responders being not at hand so far. Likewise, neurobiological reasons for drug response are still elusive. Here, we examined the global transcriptional response of MPH on lymphoblastoid cell lines (LCLs) derived from ADHD patients and unaffected controls.

Project description:Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder widely observed from childhood to adulthood, with methylphenidate (MPH) used as the first-line treatment. Recent evidence suggests that the preconception paternal environment can affect offspring health, potentially extending to multiple generations. In our previous study, we reported that MPH administration to sires induced decreased anxiety-related behaviors and memory impairment in the F1 generation. To extend these findings and examine the range of transgenerational effects, this study investigated the impact of preconception male MPH exposure on brain gene expression in the F2 generation.
