A 2026 polysomnography study involving 685 children found that neck-to-height ratio identified moderate/severe pediatric obstructive sleep apnea better than BMI Z-score, waist-to-height ratio, or hip-to-height ratio. The signal was useful but not diagnostic: neck-to-height ratio reached AUC 0.781 overall, which is strong enough for triage but not strong enough to replace a sleep study.1 Research …
Attention-Deficit Hyperactivity Disorder (ADHD) is a complex neurodevelopmental condition that has puzzled researchers and clinicians for decades. Recent studies have begun to unravel the intricate relationship between ADHD and the glutamatergic system, a major neurotransmitter pathway in the brain. A newer study evaluated the roles of cyclin-dependent kinase 5 (CDK5), microtubule-associated protein-2 (MAP2), guanylate kinase-associated …
Attention-deficit/hyperactivity disorder (ADHD) is a common childhood-onset neurodevelopmental disorder characterized by developmentally inappropriate levels of inattention, hyperactivity, and impulsivity. While highly heritable, the heterogeneity of clinical presentation suggests complex interactions between genetic and environmental risk factors. A new study suggests that it may be possible to diagnose ADHD or detect ADHD susceptibility risk in children …
