Understanding ADHD Biology
Attention, motivation, working memory and impulse control depend on interacting brain networks and chemical signals. ADHD research examines these systems alongside development, genetics and everyday functioning. Different people experience different combinations of difficulties.
Dopamine and reward
Dopamine helps regulate reward processing, motivation and attention. Research connects dopamine pathways with ADHD-related difficulties in sustaining effort and responding to rewards. The picture involves signalling and brain circuits, rather than a single universal dopamine level. [1]
Noradrenaline and attention
Noradrenaline supports alertness and the regulation of attention. It works with dopamine in prefrontal brain networks involved in working memory and behavioural control. The effects depend on the strength and location of signalling. [2]
Executive function in daily life
Executive functions help you begin tasks, plan, hold information in mind, manage time and control impulses. Difficulties in these areas help explain why someone can understand a task yet struggle to start or finish it consistently. [3
