Sleep disorders in headache: chronic daily headache, waking headache and morning headache all suggest sleep disorders, including sleep-related breathing disorders, insomnia, circadian rhythm disturbances and heterogeneous sleep. The investigators analyzed data from 1207 patients who met the (ICH-II) migraine profile, 75.9% of whom had triggers for their migraine attacks, with 49.8% of those triggers being sleep disorders. In particular, sleep has been most studied in relation to its relationship in the most common migraine patients. Decreased sleep quality has been observed in some chronic headache patients, and good sleep hygiene can reduce the number and duration of migraine attacks. Migraine attacks sometimes occur during nighttime sleep or daytime naps, and migraine attacks are closely related to the length of the previous night’s sleep. Headaches in sleep disorders: Recent studies have shown that most patients with sleep disorders have headaches and that severe headaches increase the prevalence of sleep disorders. The prevalence of headache is significantly higher in the sleep-disordered population than in the general population [5]; insomnia is a common symptom in patients with chronic daily headache. Obstructive sleep apnea syndrome is one of the more common sleep disorders associated with waking headache episodes, and sleep obstructive headache (ICH-II) is currently seen in migraine, tension-type headache, cluster and non-specific headache. Stress or stress is thought to be a common underlying factor in both sleep disorders and headaches. And both disorders have been significantly correlated with anxiety and depression. Sleep disorders are the primary cause of migraine attacks, while stress is only a secondary factor. The study found that complaints of sleep disorders were very common in migraine patients, with 1/3 of 1283 patients having difficulty with sleep initiation and maintenance.
