Mean platelet volume in children with attention deficit hyperactivity disorder

Area of Science:

• Pediatrics
• Hematology
• Cardiovascular Disease Research

Background:

• Mean platelet volume (MPV) reflects platelet size and function, and is a prognostic biomarker in cardiovascular disease.
• Childhood attention deficit hyperactivity disorder (ADHD) is hypothesized as a potential risk factor for adult coronary heart disease (CHD).

Purpose of the Study:

• To investigate mean platelet volume (MPV) and platelet count (PLT) in children diagnosed with ADHD.
• To compare MPV and PLT levels between children with ADHD and healthy controls.

Main Methods:

• MPV and PLT were measured in 70 children with ADHD (aged 6-16 years).
• A control group of 41 healthy children was included for comparison.
• Statistical analysis was performed to compare the groups.

Main Results:

• Mean platelet volume (MPV) was significantly elevated in the ADHD group compared to the healthy control group (p=.006).
• Platelet count (PLT) showed no significant difference between the ADHD and control groups (p>.05).

Conclusions:

• This study is the first to report elevated MPV levels in children with ADHD.
• The underlying reasons for increased MPV in ADHD require further investigation.
• Future research should explore the relationship between childhood ADHD, MPV, and adult coronary heart disease.
