From the Guidelines

Headaches due to obstructive sleep apnea (OSA) that do not improve with CPAP use may require alternative therapies, such as mandibular advancement devices (MADs) or lifestyle modifications, as suggested by the American College of Physicians guideline 1. When CPAP therapy is optimized, and headaches persist, it is essential to consider other factors that might be contributing to the headaches, such as mask issues, pressure settings, or underlying conditions like medication overuse headaches, migraines, or tension headaches. Some key points to consider in managing headaches due to OSA include:

  • Ensuring proper CPAP therapy by checking mask fit, pressure settings, and consistent usage
  • Considering alternative therapies like MADs, as recommended by the American College of Physicians guideline 1
  • Adding a humidifier to the CPAP system to prevent nasal dryness and related headaches
  • Lifestyle modifications, including regular sleep schedule, proper hydration, caffeine reduction, and stress management techniques, as suggested by the European Respiratory Society guideline on non-Cpap therapies for OSA 1
  • Consulting a healthcare provider for further evaluation and potential additional testing to identify other underlying causes of headaches. It is crucial to address the root cause of the headaches while providing temporary relief with common headache medications like acetaminophen or ibuprofen. The European Respiratory Society guideline on non-Cpap therapies for OSA 1 provides recommendations on alternative therapies, which can be considered for patients who do not respond to CPAP therapy. Ultimately, a comprehensive approach that includes optimizing CPAP therapy, considering alternative therapies, and addressing lifestyle factors can help manage headaches due to OSA.

From the Research

Headaches due to OSA not improved by CPAP use

  • The study 2 found that while CPAP therapy can improve headaches in some patients with OSA, not all patients experience improvement, with only 13 out of 33 patients reporting improvement in headaches specifically due to CPAP therapy.
  • The presence of witnessed apneas and male gender were found to predict improvement in headaches due to CPAP 2.
  • Another study 3 noted that symptomatic patients with moderate-severe OSA generally have good adherence to CPAP therapy, but those with mild OSA, female, young, and generally paucisymptomatic, have lower CPAP adherence.
  • Alternative treatments to CPAP, such as oral appliance therapy, upper airway stimulation, and oropharyngeal exercises, have shown promise in improving OSA symptoms, including headaches 4, 5.
  • A study 6 highlighted the importance of tailoring OSA therapy to individual patients, taking into account their specific needs and preferences.

Limitations of CPAP therapy

  • CPAP therapy is not well-tolerated by all patients, with side effects and low adherence rates being common issues 4.
  • The study 3 noted that CPAP adherence can be as low as 50% in certain populations.
  • Alternative treatments may be more viable options for patients who are intolerant of CPAP or have low adherence rates 4, 5.

Alternative treatments for OSA

  • Oral appliance therapy has been shown to be effective in improving OSA symptoms, including headaches, with higher acceptance and subjective adherence rates compared to CPAP 5.
  • Upper airway stimulation has been found to reduce OSA severity by 68% in one study 5.
  • Oropharyngeal exercises have been shown to ameliorate OSA and snoring in several studies 5.
