What Is the Impact of Brain Structure and Function on Depression in ADHD?

Posted August 19, 2025 Updated August 19, 2025 Author: Harriet Winslow, BSc Reviewed by: Dr. Rebecca Fernandez, MBBS

ADHD MRI research has revealed that individuals with ADHD often experience structural and functional brain differences that can contribute to co-occurring conditions such as depression. Studies, including brain scans ADHD, suggest that areas of the brain responsible for regulating emotions, such as the prefrontal cortex and amygdala, may show underactivity in individuals with ADHD. These brain differences can make it harder for individuals to manage their emotions, leading to increased vulnerability to ADHD behaviour such as impulsivity and mood swings, which are linked to depression.

Further ADHD MRI research supports the idea that these structural differences may impair connectivity between key brain regions, affecting both emotional regulation and motivation.

ADHD cognitive issues, such as difficulty with attention, executive function, and self-regulation, can also contribute to the development of depression in those with ADHD. Feelings of frustration, failure, and low self-esteem are recognised risk factors for depression and can stem from these cognitive difficulties. Additionally, prenatal risk ADHD factors, such as maternal stress or substance use during pregnancy, can affect brain development and increase the likelihood of both ADHD and depression in later life.

How It Helps

Understanding the connection between brain structure ADHD and depression can help guide treatment strategies. Addressing the underlying brain function issues through therapy, medication, and behavioural interventions can help reduce the symptoms of both ADHD and depression.

Improved Emotional Regulation

Therapy and medication can help regulate the emotional responses associated with both ADHD and depression.

Reduced Cognitive Struggles

Addressing ADHD cognitive issues can improve focus and self-esteem, which helps to alleviate feelings of depression.

By targeting ADHD brain function, individuals can experience relief from both ADHD and depression, improving their overall mental health and quality of life.
