A potential diagnostic blood test for attention deficit hyperactivity disorder

Area of Science:

• Neuroscience
• Biomarkers
• Diagnostic Tools

Background:

• Diagnosis of attention deficit hyperactivity disorder (ADHD) is often controversial due to subjective diagnostic procedures.
• The increasing diagnosis rates in children, adolescents, and adults highlight the need for more objective diagnostic methods.
• A novel blood test measuring blood cell membrane potential, termed membrane potential ratio (MPR™), has been developed.

Purpose of the Study:

• To investigate the potential diagnostic utility of the MPR™ blood test for ADHD.
• To assess the accuracy of MPR™ in differentiating individuals with and without ADHD.

Main Methods:

• A cross-sectional study involving consecutive outpatients (children, adolescents, adults) diagnosed with ADHD or without.
• Blood samples were collected to measure the membrane potential ratio (MPR™).
• Statistical analysis compared MPR™ values between ADHD and non-ADHD groups.

Main Results:

• Individuals with ADHD exhibited significantly higher MPR™ values (0.804 ± 0.0381) compared to non-ADHD individuals (0.684 ± 0.0260; P < 0.05).
• The MPR™ test demonstrated a sensitivity ranging from 0.75 to 0.9 and a specificity of 0.75.
• These findings suggest a depolarization in ADHD subjects compared to controls.

Conclusions:

• The MPR™ blood test shows potential as a viable diagnostic tool for ADHD.
• Further research with larger, standardized studies is warranted to confirm these findings, considering medication and comorbidity.
• Exploration of age and gender variables in relation to MPR™ is recommended.
