Relation of melatonin to sleep architecture in children with autism.

Amore et al. (2011) watched sleep and melatonin in autistic children. They used overnight urine to measure 6-SM, a melatonin by-product. They also tracked sleep stages with EEG.

The kids were aged 4-10. All had autism spectrum disorder. No pills were given; the team just observed natural levels.

Children who made more melatonin had more deep N3 sleep. They also had less light N2 sleep and felt less sleepy the next day.

In short, higher natural melatonin went hand-in-hand with better, deeper sleep.

Wright et al. (2011) ran a crossover trial in the same year. They gave autistic kids extra melatonin and saw almost an hour more sleep. M et al. show the natural side; Barry shows the pill side. Together they tell a clear story: melatonin matters.

Van Hanegem et al. (2014) later checked blood levels in kids who responded to low-dose melatonin. They found normal drug handling, so you do not need fancy labs before prescribing. M et al. set the stage; E et al. give you the green light to act.

Tyrer et al. (2006) tried controlled-release melatonin earlier. All 25 children slept better, and gains lasted two years. M et al. help explain why: melatonin nudges sleep architecture toward the deep, slow-wave kind.

If an autistic client wakes tired, check melatonin before writing it off as behavior. Ask the pediatrician for a simple overnight urine test. If levels are low, a small nightly pill can deepen sleep and cut daytime fatigue. Pair the data with parent diaries to show families why you are recommending melatonin and how to track gains.
