La melatonina nei disturbi del sonno in bambini e adolescenti con problemi neurocomportamentali

Melatonin, a neurohormone produced by the pineal gland, regulates the sleep-wake circadian rhythm. Sleep disorders are prevalent in children, especially those with neurodevelopmental disorders like autism and other neurodisabilities and affect about 50-75% of this population. The use of melatonin to improve sleep in this population has been debated for over 20 years, with recent re-views addressing its efficacy and safety. Melatonin significantly improves sleep latency and total sleep time in children with autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and other neurodevelopmental disorders. However, its effectiveness in reducing night awakenings is limited. Short-term use shows no significant association with serious adverse effects, though mild side effects like headache, nausea, drowsiness, and mood changes are common. Long-term safety data are limited but suggest no significant impact on puberty onset or bone health. Dosing and timing of melatonin administration vary widely, and individualized treatment plans are recommended. The use of melatonin should be accompanied by behavioural interventions, and potential side effects should be monitored closely.
