Genes impacting serotonin activity may also play a role (Henriquez et al, 2008; Soo-Churi et al, 2012; Gazer et al 2008, Franke et al, 2010). There is a great deal of evidence that AD/HD runs in families, which is suggestive of genetic factors. Recent studies suggest that anywhere from 40-60% of children of adults with ADHD will also have the condition (Biermann et al., 1992; Medina et al, 2003; Barkley, 2008). As stated above there are various genes like the receptor DRD4 and D2 and DATI that causes one to developed Attention-deficit attention disorder and because of these damaged genes and if parents has it is most likely that their children with have this mental illness which is provided by the recent studies that 40-40-60% of children of adults with ADHD will also have the condition not only with these genes but also because of Exposure to environmental toxins during pregnancy.
