Focused ADHD News – Exploring ADHD symptoms.
Up till now, no study has been done to look into the association between specific gene variants and other environmental risk factors that contribute to the development of ADHD in children. Previous behavioural and emotional dysregulation studies centred on genetic and environmental influences separately; according to Molly Nikolas of the Michigan State University.
In new ADHD news, a team of researchers looked into the role of the 5HTTLPR, a key serotonin genetic region, in 304 youths that had the tendency of blaming themselves for the arguments of their parents. The prevalence of ADHD symptoms was higher in those with both high and low serotonergic activity or expressed more self-blame.
As a functional genetic region associated with the regulation and production of protein for the transportation of neurotransmitter serotonin, the 5HTTLPR has also been linked with numerous personality and neuropsychiatric disorders. According to the researchers, the findings reinforced a compendium of evidence that ADHD in certain environments can be activated by 5HTTLPR variants.
In exploring the influences to ADHD, Nikolas and the team found the possibility of alterations in the neurotransmission system of serotonin as a possible cause of ADHD. Psychosocial distress only aggravates the condition especially where inter-parental conflicts are observed. The uncovering of the relationship between self-blame and low and high serotonin activity can lead to more responsive treatment techniques for ADHD in both children and adolescents.
