Which of the following is NOT a subtype of Breathing-Related Sleep Disorder in DSM-5?

• A. Obstructive Sleep Apnea Hypopnea
• B. Central Sleep Apnea
• C. Sleep-Related Hypoventilation
• D. Sleep-Related Hyperventilation

Answer: (C)

The key idea here is which breathing problems are formally recognized as Breathing-Related Sleep Disorders in DSM-5. That category includes disorders marked by abnormal breathing during sleep: Obstructive Sleep Apnea Hypopnea, where the airway collapses during sleep but breathing effort remains; Central Sleep Apnea, where the brain’s drive to breathe temporarily ceases; and Sleep-Related Hypoventilation, where ventilation during sleep is insufficient, causing elevated CO2. Sleep-Related Hyperventilation, on the other hand, is not listed as a DSM-5 subtype within Breathing-Related Sleep Disorders. Hyperventilation would involve excessive ventilation and low CO2, which isn’t established as its own DSM-5 breathing-related sleep disorder. Therefore, Sleep-Related Hyperventilation is not a defined subtype in this DSM-5 category.
