Attention Deficit Disorder is exogenous or pathological
Answers
The pathology of ADHD is not clear. Psychostimulants (which facilitate dopamine release) and noradrenergic tricyclics used to treat this condition have led to speculation that certain brain areas related to attention are deficient in neural transmission.
Attention-deficit/hyperactivity disorder (ADHD) is a childhood onset disorder with the cardinal features of inattention, impulsivity, and hyperactivity. And the core symptoms of ADHD in childhood will gradually change into more serious neurological disorders in adulthood. Thus, it is necessary to study the pathological and physiological mechanisms of adult ADHD patients. Compared with normal people, patients with ADHD have stronger exogenous stimulation drive ability and weaker endogenous control ability. Therefore, the reason why ADHD in adults is susceptible to external interference is whether the level of response generated exogenous stimulation is too strong or the level of response generated by endogenous driving is too weak.

Three experimental paradigms of saccade (reverse saccade, memory-oriented saccade and visual-oriented saccade) were used to investigate the ability of endogenous and exogenous saccade conversion and the ability of endogenous and exogenous saccade production and maintenance.
