How does maternal smoking impact brain structure and function and ADHD risk? 

ADHD brain imaging has shown that maternal smoking during pregnancy can significantly impact brain structure and function, increasing the risk of developing ADHD. Nicotine and other harmful substances in cigarettes can affect the developing brain, particularly areas responsible for attention, impulse control, and emotional regulation. These alterations are linked to the ADHD behaviour commonly observed in children born to mothers who smoke during pregnancy. 

Studies using brain scans ADHD have revealed structural differences in regions like the prefrontal cortex and basal ganglia, which are involved in decision-making, focus, and emotional regulation. Prenatal exposure to nicotine disrupts the development of these regions, leading to ADHD behaviour such as inattention, hyperactivity, and impulsivity. These findings highlight the prenatal risk ADHD and its long-term impact on brain development. 

Common Symptoms Linked to Maternal Smoking and ADHD 

Here are some common symptoms associated with maternal smoking during pregnancy and ADHD brain imaging: 

Difficulty focusing and maintaining attention

Children exposed to maternal smoking often struggle to concentrate, particularly in environments requiring sustained attention. This is linked to changes in the prefrontal cortex. 

Impulsivity and emotional regulation challenges

Impulsive behaviours and difficulty controlling emotions are common in children exposed to maternal smoking. These symptoms are often related to disruptions in the basal ganglia and ADHD behaviour.
