Attention-deficit/hyperactivity disorder and attention networks

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Attention-deficit/hyperactivity disorder (ADHD) research has advanced our understanding of cognitive functions.
• Historical models of attention have shaped neurocircuitry models of ADHD.

Purpose of the Study:

• To review the neuropathophysiology of ADHD and its bidirectional relationship with normal cognition.
• To integrate findings from ADHD research into broader neuroscience contexts.
• To explore neurocircuitry models of ADHD and their connection to attention mechanisms.

Main Methods:

• Literature review integrating historical perspectives and current research.
• Analysis of neurocircuitry models of ADHD.
• Selective review of neuroimaging data in ADHD.

Main Results:

• ADHD research illuminates normal attention, cognition, and brain function.
• Key neural systems implicated in ADHD include attention networks, reward processing, and default mode networks.
• Neuromodulatory factors play a role in these systems.

Conclusions:

• Understanding ADHD neuropathophysiology enhances knowledge of normal brain function.
• Future research should explore interactions within neural systems and neuromodulatory influences.
• Neuroimaging data provides valuable insights into both ADHD and general brain mechanisms.
