Disrupted brain connections seen in young ADHD patients

30 April 2014 

A new study has indicated that young people with attention deficit hyperactivity disorder (ADHD) may exhibit disrupted connections in their brains. 

According to the research, published in journal Radiology, children and adolescents with ADHD have disrupted connections between different areas of the brain that are evident on resting-state functional magnetic resonance imaging (rfMRI). 

The authors believe that the finding could help to boost early, accurate diagnosis of the condition. 

ADHD, which affects around five per cent of children and young people worldwide, is characterised by degrees of inattention, hyperactivity and impulsiveness that are beyond what is classed as normal in individuals of various ages. 

While evidence has implicated the brain’s frontostriatal circuit in the condition, the specific brain physiology is yet to be properly understood. 

Results from the study showed that patients with the condition had a different structure and function located in areas of the brain such as the orbitofrontal cortex, which is primarily involved in the cognitive processing of strategic planning. This was also evident in the globus pallidus, which is involved in executive inhibitory control.
