For example, when individuals suffer from a mutation that causes them to have low levels of serotonin, there is an observed increase in impulsivity and depression [8] With neurotransmitters playing a central role in the development of aggressive behaviour, it follows that many of the gene mutations that have been implicated with aggressive ...
Certain genes influence the volume of key brain regions, which, in turn, could play a role in the development of Parkinson's disease and ADHD, a new study suggests. Parkinson’s, ADHD tied to ...
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience. These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development , and continues to develop ...
Structural racism creates barriers in housing, employment and economic opportunity for Black people and other people of color. Now, a new study has found it can also have a harmful impact on ...
