How does brain structure and function affect attention regulation in ADHD? 

Understanding the role of attention regulation in ADHD brain is central to grasping why individuals with ADHD often struggle to focus or switch between tasks effectively. Differences in brain structure and function are now known to be major contributors to the ADHD attention deficits seen across age groups. 

Although the prefrontal cortex is the primary component of the brain’s attention network, other regions are also involved. In people with ADHD, this area may be underdeveloped or less active, making sustained attention, task prioritisation, and decision-making more difficult. ADHD brain deficits can also lead to weaker or less coordinated connections between the prefrontal cortex and other areas, such as the parietal lobe and basal ganglia. This disruption can hinder the smooth processing of incoming information and impair the ability to shift focus when necessary. 

Key Signs of Attention Challenges 

These symptoms are commonly tied to how brain function affects attention control in ADHD: 

Trouble focusing or zoning out

People may find themselves frequently daydreaming or unable to concentrate on tasks. This is linked to poor communication within the brain’s attention network. 
 

Difficulty switching tasks or staying organised

Struggles with transitioning between activities or following plans are signs of weakened executive functioning.
