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.
People with classic ADHD are more likely to be rejected in these situations because of their social intrusiveness or aggressive behavior. Compared to children with CDS, they are also much more likely to show antisocial behaviours like substance abuse , oppositional-defiant disorder or conduct disorder (frequent lying, stealing, fighting etc ...
ADHD inattentive type: Must score either a 2 or 3 on six or more items in questions 1–9, and score of 1 or 2 on any items in the performance section. ADHD hyperactive/impulsive type: Must score either a 2 or 3 on six or more items in questions 10–18, and a score of 1 or 2 on any items in the performance section.
With 15.5 million U.S. adults currently diagnosed with ADHD, there is a growing focus on warning signs of the disorder. Mental health experts share the most common signs and symptoms.
The task is made more challenging by the shifting of modalities between the visual and auditory stimuli. In the five "high demand" sections of the test, the targets are presented frequently. This creates a continuous response set so when the test-taker is suddenly presented with a foil, he or she may find it difficult to "put on the brakes."
Thus, a decrease in executive dysfunction in adults with ADHD as compared to children with ADHD is thought reflective of compensatory strategies employed on behalf of the adults (e.g. using schedules to organize tasks) rather than neurological differences. Although ADHD has typically been conceptualized in a categorical diagnostic paradigm, it ...
Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control. [1] Each pathway is a set of projection neurons, consisting of individual dopaminergic neurons.
[8] [21] The biggest difference between autistic and non-autistic stimming is the type of stim and the quantity of stimming. [21] In the Diagnostic and Statistical Manual of Mental Disorders , published by the American Psychiatric Association , stimming behavior is described as "stereotyped or repetitive motor mannerisms" and listed as one of ...
