Neurological factors also contribute to ADHD, with research showing differences in brain structure and function in individuals with the disorder.

Key neurotransmitters, such as dopamine and norepinephrine, are involved in regulating attention, impulse control, and other executive functions.

Imbalances or disruptions in these neurotransmitter systems can lead to the development of ADHD symptoms.

Moreover, studies have identified differences in brain volume, connectivity, and activation patterns between individuals with ADHD and those without the disorder.
