What Does EEG Show About Brain Structure and Function in ADHD? 

Electroencephalography (EEG) is a technique used to measure electrical activity in the brain, providing valuable insights into ADHD brain function. Brain scans ADHD, including EEG studies, have shown that individuals with ADHD often exhibit abnormal brainwave patterns, particularly in areas of the brain responsible for attention, behaviour, and cognitive control. These abnormalities in brain activity are closely linked to ADHD behaviour, such as inattention, impulsivity, and hyperactivity. 

EEG findings in people with ADHD often show an increased presence of slow brainwaves, such as theta waves, which are typically associated with drowsiness or daydreaming. Conversely, faster brainwaves, like beta waves, which are linked to focus and concentration, may be underactive. These differences in brainwave patterns highlight the ADHD cognitive issues that individuals face, as their brain function is less efficient when it comes to sustaining attention and controlling impulses. 

Common Symptoms of ADHD Linked to Brain Function Abnormalities Revealed by EEG 

The brainwave abnormalities identified through brain scans ADHD can help explain several common symptoms of ADHD, including: 

Inattention

Slow brainwave activity, particularly in regions responsible for sustained attention, leads to difficulty concentrating for long periods.  

Impulsivity

Reduced beta wave activity in the frontal lobe makes it harder for individuals to control their impulses, leading to spontaneous actions, such as interrupting others or making snap decisions without thinking through consequences. 

Hyperactivity

Imbalances in brainwave activity can cause restlessness and excessive movement, which is common in children with ADHD. This can manifest as an inability to sit still, fidgeting, or an overwhelming need to be constantly in motion, even when it is inappropriate or unnecessary. 

Emotional Dysregulation

Abnormalities in brainwave patterns related to emotional processing can lead to difficulties managing emotions. 

By understanding how ADHD brain function is reflected in brain scans ADHD and EEG patterns, we can gain a deeper understanding of ADHD behaviour and better tailor interventions to help manage ADHD symptoms effectively.
