Insights
High-dose melatonin significantly improved sleep patterns in a blind child with a sleep/wake cycle disorder. This study highlights melatonin
Area of Science:
- Pediatric Neurology
- Sleep Medicine
- Chronobiology
Background:
- Disordered sleep-wake cycles are common in blind children.
- Melatonin is a hormone that regulates sleep.
Purpose of the Study:
- To evaluate melatonin's effectiveness and safety for sleep normalization in a blind child.
- To determine optimal melatonin dosage for treating sleep rhythm disorders.
Main Methods:
- A double-masked, randomized treatment trial was conducted.
- The study compared placebo, a physiological dose (0.14 mg), and a supraphysiological dose (2.2 mg) of melatonin.
- Sleep onset and offset were monitored.
Main Results:
- Placebo and low-dose melatonin showed erratic sleep patterns.
- High-dose melatonin (2.2 mg) significantly improved sleep onset and offset.
- No adverse events were reported.
Conclusions:
- Melatonin, particularly at higher doses, can be effective for treating disordered sleep rhythms in blind children.
- This study demonstrates a protocol for dose adjustment to optimize treatment outcomes.
- Further research into melatonin's role in pediatric sleep disorders is warranted.
Abstract:
We assessed the effectiveness and safety of melatonin in normalizing sleep in a 7-year-old blind child with a longstanding sleep/wake cycle disorder, using a double-masked, randomized treatment trial of placebo, a physiological dose (0.14 mg) and a supraphysiological dose (2.2 mg) of melatonin. Sleep onset and sleep offset were erratic and inappropriately early with placebo and low dose melatonin, but improved significantly on high dose melatonin. This report confirms that melatonin may be effective in treatment of disordered sleep rhythm in blind children, and illustrates a protocol that enables dose adjustment for optimal treatment response.

The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...
