Narcolepsy is associated with high prevalence of comorbid sleep disorders. Overlap in symptoms of different disorders may confound management. Sleep Medicine practitioners need to be vigilant for presence or new development of comorbid conditions to provide effective and comprehensive care. We present a patient with Narcolepsy Type 2 who developed worsening hypersomnolence due to new onset Obstructive Sleep Apnea (OSA). Treatment of OSA resulted in improvement of hypersomnolence without requiring change in therapy for Narcolepsy.
