The Role of GDNF and NSE in Attention-Deficit/Hyperactivity Disorder: Relationships with Sleep and Eating Behaviors

This study examined blood levels of glial cell line-derived neurotrophic factor (GDNF) and neuron-specific enolase (NSE) in 51 children with ADHD and 20 healthy controls, assessing correlations with sleep patterns and eating behaviors. NSE levels were significantly elevated in ADHD children compared to controls, and GDNF showed a negative correlation with eating scale scores, suggesting potential neurobiological markers warrant further investigation.
