The neurodevelopmental disorders cluster encompasses disorders rooted in early brain development. This cluster is primarily defined by a strong shared genetic foundation between autism spectrum disorder (ASD) and ADHD. This strong genetic overlap suggests that a core set of genes influences early brain development, shaping connectivity, synaptic function, and the regulation of attention and social behavior. The compulsive disorders cluster has a shared genetic component for disorders centered on intrusive thoughts and repetitive behaviors. By analyzing a patient's genetic profile, doctors could pinpoint their specific risk patterns, like a high genetic tendency for depression, anxiety or PTSD.
