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 ...
ADHD arises from brain maldevelopment especially in the prefrontal executive networks that can arise either from genetic factors (different gene variants and mutations for building and regulating such networks) or from acquired disruptions to the development of these networks and regions; involved in executive functioning and self-regulation.
Adult Attention Deficit Hyperactivity Disorder is the persistence of attention deficit hyperactivity disorder (ADHD) into adulthood. It is a neurodevelopmental disorder, meaning impairing symptoms must have been present in childhood, except for when ADHD occurs after traumatic brain injury.
Nance-Horan syndrome protein is a protein that in humans is encoded by the NHS gene. [5] This gene encodes a protein containing four conserved nuclear localization signals. The encoded protein may function during the development of the eyes, teeth, and brain. Mutations in this gene have been shown to cause Nance-Horan syndrome. An alternative ...
The hypothesis notes that humans spent most of their evolutionary history in hunter-gatherer societies, and it argues that ADHD represents a lack of adaptation to farming societies. Hartmann first developed the idea as a mental model after his own son was diagnosed with ADHD, stating, "It's not hard science, and was never intended to be." [1]
Attention deficit hyperactivity disorder predominantly inattentive (ADHD-PI or ADHD-I), [3] is one of the three presentations of attention deficit hyperactivity disorder (ADHD). [4] In 1987–1994, there were no subtypes or presentations and thus it was not distinguished from hyperactive ADHD in the Diagnostic and Statistical Manual (DSM-III-R).
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.
