ADHD brain function can be significantly impacted by exposure to environmental pollution. Research has shown that pollution, especially during pregnancy, can interfere with brain development, causing structural and functional changes that elevate the risk of developing ADHD. These changes are most evident in areas of the brain responsible for attention, impulse control, and emotional regulation that are the key factors in ADHD behaviour. 

Pollution exposure during pregnancy poses a prenatal risk ADHD, as it can affect the brain’s early development, particularly the prefrontal cortex and basal ganglia. These areas are crucial for decision-making, attention, and impulse control. Structural damage to these regions can lead to the symptoms of ADHD, such as inattention, impulsivity, and hyperactivity, which are commonly observed in ADHD behaviour. Brain scans ADHD often reveal these structural changes, helping to understand the link between pollution exposure and ADHD risk.

Common Symptoms Linked to Pollution Exposure and ADHD 

Here are some common symptoms associated with pollution exposure and ADHD brain function: 

Difficulty focusing and maintaining attention

Children exposed to pollution, particularly during early development, often find it hard to concentrate. This is linked to alterations in the prefrontal cortex, which is responsible for focus and decision-making. 

Impulsivity and emotional regulation issues

Impulsive behaviours, such as acting without thinking or emotional outbursts, are common in children exposed to pollution. These behaviours are often linked to changes in the basal ganglia, which controls motor regulation and emotional responses.
