Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.3K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Motor and Sensory Areas of the Cortex

8.8K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

Summary

Attention deficit hyperactivity disorder (ADHD) is linked to increased gray matter (GM) in motor areas for children. This finding contrasts with previous studies suggesting reduced GM in ADHD patients.

Area of Science:

  • Neuroscience
  • Developmental Psychology

Background:

  • Conflicting findings exist regarding gray matter (GM) volume in individuals with Attention Deficit Hyperactivity Disorder (ADHD).
  • Some studies report reduced GM, others no difference, and some increased GM in ADHD patients compared to controls.
  • This variability highlights the need for further research to accurately define GM alterations in ADHD.

Purpose of the Study:

  • To investigate gray matter (GM) alterations in children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD).
  • To utilize pediatric templates for a more accurate assessment of GM differences.
  • To explore the relationship between GM volume and ADHD symptom severity.

Main Methods:

  • Magnetic resonance imaging (MRI) scans were performed on 19 drug-naïve ADHD patients and 18 age-matched controls.
  • Participants' ages ranged from 7 to 14 years.
  • Analysis employed pediatric templates for standardized GM volume assessment.

Main Results:

  • ADHD patients exhibited greater GM volume compared to controls.
  • The increased GM was predominantly observed in the precentral and supplementary motor areas.
  • Positive correlations were found between GM volume in these motor regions and ADHD symptom severity scores.

Conclusions:

  • The study identified increased GM in specific motor areas in children with ADHD.
  • These findings challenge the notion of universally reduced GM in ADHD.
  • Further research is required to understand the clinical and pathophysiological implications of increased GM in the motor cortex of individuals with ADHD.
