Persistent Childhood Primitive Reflex Reduction Effects on Cognitive, Sensorimotor, and Academic Performance in ADHD

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder.
• Retained Primitive Reflexes (RPRs) are associated with developmental delays and learning difficulties.
• Current interventions for ADHD often focus on medication and behavioral therapy, with limited emphasis on RPRs.

Purpose of the Study:

• To evaluate the efficacy of a hemispheric-based training program in reducing RPRs in individuals with ADHD.
• To examine the relationship between RPR reduction and improvements in motor and cognitive functions.
• To assess the impact of the program on academic performance measures.

Main Methods:

• A study involving 2,175 individuals aged 3.2 to 22.04 years diagnosed with ADHD.
• Participants were recruited from 89 satellite clinics across the United States.
• A 12-week hemispheric-based training program was implemented, with assessments of RPRs, motor function (metronome-based motor, DL tasks), and cognitive tasks (Wechsler Wide Range Achievement Test subtests).

Main Results:

• Significant reduction in extant retained primitive reflexes (RPRs) post-intervention.
• Significant improvements observed in all measured motor and cognitive functions.
• Listening comprehension increased by 7% (p < 0.0001) and mathematical problem-solving by 5% (p < 0.0001).

Conclusions:

• Hemispheric-based training is effective in reducing RPRs in individuals with ADHD.
• The program leads to significant enhancements in motor and cognitive performance.
• Incorporating such programs into educational systems could be a cost-effective method to improve academic, cognitive, and motor outcomes globally.
