Overview
The diagnosis of sleep apnea is is listed in the DSM-V guidelines using one of two indices, Apnea Hyponea Index (AHI) or Respiratory Disturbance Index (RDI).
Sleep Apnea Diagnosis Criteria
The common indices used to assess breathing are Apnea Hyponea Index (AHI) and Respiratory Disturbance Index (RDI)
- AHI is the number of apneas or hypopneas recorded during the study per hour of sleep
- RDI is the average number of respiratory disturbances (obstructive apneas, hypopneas, and respiratory event-related arousals [RERAs]) per hour.
- None/Minimal: < 5 per hour
- Mild: ≥ 5, but < 15 per hour
- Moderate: ≥ 15, but < 30 per hour
- Severe: ≥ 30 per hour
DSM-V Diagnostic Criteria for Central Sleep Apnea[1]
Either criterion 1 or 2 must be met:
1. Evidence by polysomnography of AHI or RDI greater than or equal to 5 and less than or equal to 14 events per hour of sleep and either of the following sleep symptoms:
- Nocturnal breathing disturbances: snoring, snorting/gasping, or breathing pauses during sleep.
- Daytime sleepiness, fatigue, or unrefreshing sleep despite sufficient opportunities to sleep that is not better explained by another mental disorder (including a sleep disorder) and is not attributable to another medical condition.
2. Evidence by polysomnography of AHI or RDI greater than or equal to 15 events per hour of sleep regardless of accompanying symptoms
DSM-V Diagnostic Criteria for Central Sleep Apnea[1]
Criterion 1 and 2 must be met: 1.Evidence by polysomnography of AHI or RDI greater than or equal to 5 events per hour of sleep
2. The disorder is not better explained by another current sleep disorder
