What brain structure and function abnormalities in the basal ganglia cause ADHD? 

Basal ganglia abnormalities ADHD are crucial to understanding the role brain structure and function play in the development of ADHD. The basal ganglia, a group of structures deep within the brain, are responsible for controlling movement, behaviour, and emotional regulation. The brain’s capacity to control attention, impulse control, and motor functions, all of which are important aspects of ADHD, can be severely impacted by abnormalities in these regions. 

In individuals with ADHD, basal ganglia abnormalities ADHD can result in an overactive or underactive basal ganglia, affecting cognitive and behavioural functioning. These alterations could result in impulsive behaviour, hyperactivity, and attention problems, all of which are frequently seen in people with ADHD. Disruptions in the basal ganglia ADHD can also influence emotional regulation, making it harder for individuals to control their responses to stimuli or maintain focus. 

Common Symptoms Linked to Basal Ganglia Abnormalities 

Here are some common symptoms associated with basal ganglia abnormalities ADHD: 

Difficulty focusing and staying on task

Children and adults with ADHD often struggle to maintain focus, particularly on tasks that require sustained attention. This is often linked to basal ganglia abnormalities ADHD, which disrupt attention regulation. 
 

Impulsivity and hyperactivity

Impulsive behaviours, such as interrupting others or excessive movement, are common in ADHD. These symptoms are often caused by dysfunction in the basal ganglia, which regulates motor control and impulse inhibition.
