Which brain structure and function differences are linked to ADHD causes? 

Understanding the brain structure differences in ADHD is essential for grasping why some individuals struggle with attention, impulsivity, and hyperactivity. According to brain research, people with ADHD frequently show clear structural and functional abnormalities in the areas of the brain that control cognitive processes like focus, judgement, and behaviour control. These ADHD neurological causes are key to understanding the condition at a deeper level.  
 
Key areas affected in the brains of individuals with ADHD include the prefrontal cortex, basal ganglia, and cerebellum. The prefrontal cortex, which is crucial for attention and decision-making, often shows lower activity in those with ADHD. This can make focusing on tasks, such as reading or completing projects, more difficult. Similarly, the basal ganglia, which regulates motor control and emotional responses, often functions differently in people with ADHD, contributing to hyperactivity and impulsiveness. Furthermore, the cerebellum, responsible for coordination and emotional regulation, can also exhibit structural variations that influence ADHD behaviours. 

Common Symptoms 

Difficulty focusing and staying on task

People with ADHD often find it hard to concentrate, resulting in unfinished tasks or forgotten details. This symptom is commonly tied to an underactive prefrontal cortex.  

Impulsivity and hyperactivity

The impulsive and restless nature of ADHD can lead to difficulty sitting still or making hasty decisions.
