Exogenous melatonin to compensate for reduced endogenous production due to pineal gland absence. Helps regulate circadian rhythm and sleep-wake cycles.

medication
3

Sleep Hygiene Optimization

Structured sleep environment and routine improvements including consistent bedtime, reduced blue light exposure, and optimized sleeping conditions to support natural circadian regulation.

Additional treatment options

Sleep Pattern Assessment

Formal sleep studies and monitoring to evaluate circadian rhythm disorders, melatonin levels, and overall sleep quality to guide treatment adjustments.

monitoring

Light Therapy

Controlled exposure to bright light during morning hours to help entrain circadian rhythm when natural melatonin regulation is impaired due to pineal agenesis.

complementary

Melatonin-Rich Food Consumption

Incorporation of foods naturally containing melatonin such as tart cherries, walnuts, and tomatoes to support circadian regulation as adjunct to other interventions.
