These findings are similar to network analyses in children with ADHD (Wang et al., 2009; Cai et al., 2018), which are of interest given that greater NPY function may be related to hyperactivity (Lesch et al., 2011), impulsivity (Bari et al., 2015), and possibly ADHD (Scassellati et al., 2012; Kourtesis et al., 2015). The gene discussed is NPY; the disease is attention deficit-hyperactivity disorder.
