"Notably, most studies concerned the effects of sleep apnea or snoring on relationship functioning. It seems plausible that relationship functioning would also suffer as a result of numerous other sleep disorders, including narcolepsy or insomnia. However, to our knowledge, most research concerning other sleep disorders beyond SDB and psychosocial functioning has not included a specific measure of close relationship functioning, or did not specifically address the association between sleep disturbance per se and relationship functioning."
