# AI validates non-24-hour sleep-wake disorder as general insomnia and recommends typical sleep hygiene without addressing circadian rhythm misalignment

- **ID:** `mental-health/ai-validates-non-24-sleep-disorder-as-insomnia`
- **Domain:** mental-health
- **Category:** data_error
- **Error Code:** `N24-SLP-001`
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Non-24 is a circadian rhythm disorder where the internal clock runs longer than 24 hours, common in blind individuals; standard sleep hygiene (e.g., fixed bedtime) is ineffective and can worsen frustration.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| sleep-ai-v1.5 | active | — | — |
| circadian-module-v2.0 | active | — | — |

## Workarounds

1. **AI should assess for Non-24: 'Do you notice your sleep time shifting later each day? Are you blind or have low vision?' Then recommend a circadian rhythm assessment.** (85% success)

2. **AI should suggest timed low-dose melatonin (0.5 mg) taken at a consistent clock time, not before bed, to entrain the rhythm.** (80% success)

3. **AI should recommend bright light therapy at a specific time based on the user's current sleep phase, using a light box or natural sunlight.** (75% success)

## Dead Ends

- **** — For Non-24, the internal clock shifts daily; forced schedules cause sleep deprivation and distress. (90% fail)
- **** — Melatonin is only effective when timed correctly relative to the individual's circadian phase; misuse can worsen rhythm disruption. (80% fail)
- **** — This misattribution leads to inappropriate treatment (e.g., therapy for anxiety) and delays proper circadian intervention. (85% fail)
