Individuals with ADHD also display\u00a0 lower activity in brain networks\u00a0\u00a0 that are involved in attention and cognitive\u00a0 control. Typically, activity in these networks\u00a0\u00a0 increases when activity in the default\u00a0 mode network decreases, and vice versa.\u00a0\u00a0 Thus, one hypothesis is that in ADHD activity\u00a0 in the default mode network is dysregulated\u00a0\u00a0 and interferes with the function of networks\u00a0 involved in attention and cognitive control.00:01:17<\/a> Studies have also found that people with ADHD tend\u00a0 to display atypical activity in the reward system,\u00a0\u00a0 a group of structures that are\u00a0 involved in motivated behavior,\u00a0\u00a0 anticipation, and reinforced learning.\u00a0 This atypical reward system activity\u00a0\u00a0 might be associated with a tendency to\u00a0 overestimate the value of short-term rewards\u00a0\u00a0 in comparison to long-term rewards, which\u00a0 could also affect planning and decision-making.\u00a0\u00a0 The reward system includes some of the major\u00a0 dopamine pathways in the brain, and dopamine is\u00a0\u00a0 often implicated in ADHD because medications that\u00a0 are commonly used to treat the condition, such as\u00a0\u00a0 amphetamine and methylphenidate, cause increased\u00a0 transmission of dopamine and norepinephrine.
