Some patients, despite excellent treatment compliance and excellent objective measure of sleep apnea treatment efficacy, do not feel symptom relief of fatigue or sleep disruption. This may suggest the co-existence of other conditions. Non sleep related conditions include the patient’s MEDICAL STATE, such as hypothyroidism or low iron that may lead to fatigue or the patient’s PSYCHOLOGICAL STATE, such as depression, which may lead to fatigue or nonrestorative sleep.
In addition, the patient’s SLEEP BEHAVIOR AND HYGIENE, including “not sleeping enough”, may influence perception of clinical state, which may be misconstrued as lack of sleep apnea treatment efficacy. For sleep related mechanisms, external factors need to be examined, including, sleep partner night behavior, pets, noise, uncomfortable bed among others. Finally, there are other sleep disorders that may limit efficacy of sleep apnea treatment and may span insomnia to hypersomnia (excessive daytime sleepiness) that require different simultaneous treatment.
The list below include commonly seen sleep disorders.
