What prenatal exposures change brain structure and function leading to ADHD? 

ADHD brain function can be significantly affected by prenatal exposures, with certain environmental factors during pregnancy contributing to brain structure and function alterations. The normal development of the brain can be disrupted by exposure to harmful substances like alcohol, tobacco, or drugs. These disruptions may affect areas of the brain responsible for attention, behaviour control, and emotional regulation, all of which are key factors in ADHD. 

Prenatal exposure to toxins can alter the executive function of the brain, which includes the ability to plan, make decisions, and regulate behaviour. Brain scans ADHD often reveal structural differences in areas like the prefrontal cortex and basal ganglia, regions that are crucial for executive function and impulse control. Understanding ADHD causes linked to prenatal exposures highlights the importance of maintaining a healthy environment during pregnancy to support optimal brain development. 

Common Symptoms Linked to Prenatal Exposures and ADHD 

Here are some common symptoms associated with prenatal exposures and ADHD brain function: 

Difficulty focusing and maintaining attention

Children exposed to harmful substances in utero often struggle to focus, particularly on tasks requiring sustained concentration. This is linked to underdevelopment or dysfunction in areas such as the prefrontal cortex. 

Impulsivity and emotional regulation challenges

Impulsive behaviours, such as acting without thinking or difficulty controlling emotions, are common in children with prenatal exposure and ADHD. These issues are often related to changes in the basal ganglia and executive function.
