Executive dysfunction is the mechanism underlying ADHD paralysis, [2] and in a broader context, it can encompass other cognitive difficulties like planning, organizing, initiating tasks and regulating emotions. It is a core characteristic of ADHD and can elucidate numerous other recognized symptoms. [3]
Attention deficit hyperactivity disorder (ADHD) [1] is a neurodevelopmental disorder characterized by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally-inappropriate.
A meta-analysis of 37 studies on cognitive differences between those presenting ADHD-Predominantly Inattentive presentations and ADHD-Combined type found that "the ADHD-C presenting performed better than the ADHD-PI presenting in the areas of processing speed, attention, performance IQ, memory, and fluency. The ADHD-PI presenting performed ...
Unlike ADHD, which is the result of deficient executive functioning and self-regulation, [4] [5] [6] CDS presents with problems in arousal, maladaptive daydreaming, and oriented or selective attention (distinguishing what is important from unimportant in information that has to be processed rapidly), as opposed to poor persistence or sustained ...
Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD.Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training ...
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.
Cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process or different areas of cognition. [1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses.

Like directed attention fatigue, ADHD involves the prefrontal cortex. Specifically, the right prefrontal cortex is less active among children with ADHD. Experimentation has shown that the severity of ADHD symptoms can be correlated to the degree of asymmetry between blood flow in the left and right prefrontal cortex.
