Understanding the causes executive dysfunction ADHD helps explain why children and adults with ADHD often struggle with focus, organisation, and emotional control. Executive dysfunction in ADHD stems from differences in brain development, structure, and chemistry. 

One of the main causes executive dysfunction ADHD is the delayed maturation of the prefrontal cortex. This part of the brain is responsible for planning, decision-making, and impulse control. It develops more slowly in individuals with ADHD, leading to executive function challenges.

How It Helps 

ADHD brain development 

ADHD brain development follows a different trajectory than typical brain development. Research shows delayed growth in areas linked to executive function, particularly in the frontal lobe and its connections to other brain regions. 

Neurobiology of ADHD 

The neurobiology ADHD research highlights that dopamine and norepinephrine, key neurotransmitters involved in attention and self-regulation, function differently in ADHD brains. These chemical imbalances play a central role in executive dysfunction. 

Risk factors for executive deficits 

There are several risk factors executive deficits in ADHD, including genetics, prenatal exposure to substances, low birth weight, and early environmental stress. These factors can influence how the brain develops and processes information.
