Many headache patients complain of poor sleep, and sleep disturbance has been shown to play a role in chronic pain. We recorded nocturnal sleep with a 4-channel cassette EEG monitoring device in 10 common migraine patients, 10 individuals with muscle contraction (tension) headache, and 10 chronic tension-vascular headache sufferers. Migraine patients had essentially normal sleep, although rapid eye movement (REM) sleep and REM latency were increased. Patients with tension headache had reduced sleep time and sleep efficiency, decreased sleep latency but frequent awakenings, increased nocturnal movements, and marked reduction in slow wave sleep, without change in REM sleep or latency. Mixed-element headaches with both tension and vascular features were associated with reduced sleep, increased awakening, diminished slow wave sleep, and REM sleep that was decreased in amount and reduced in latency. The findings suggest that patients with intermittent migraine may have minimal sleep disturbance, while chronic headache may be worsened by chronically poor sleep. Muscle contraction headache may be associated with frequent awakenings and decreased slow wave sleep similar to the sleep changes of fibrositis, while chronic tension-vascular headache may have a depressive substrate. Four-channel sleep recording may miss contributory sleep apnea, but nonetheless cassette EEG may facilitate outpatient evaluation of refractory headaches.

From this and the previous article, the following points may be offered in summary: When comparing the elderly age group with the general population, the incidence of migraine headaches decreases with age, whereas other etiologies such as glaucoma, temporal arteritis, and cerebrovascular disease may assume a more prominent role in the differential diagnosis. Patients in the geriatric population are frequently taking a multitude of medications, and it is extremely important to carefully evaluate these for possible precipitants of headache. Furthermore, in elderly patients with other potential medical problems, particular attention should be paid to the possibility of various systemic causes of headache. Therapy for specific headache disorders should be tailored to the individual patient. Consider the patient's overall general, psychological, medical, and neurologic background. The physician must be aware of possible interactions of medications with the therapeutic intervention, as well as possible poor tolerance to specific medications due to preexisting medical or neurologic disorders. A complete history, obtaining information on the temporal pattern of headache, the distribution of pain, and precipitating and alleviating factors, is extremely important in evaluating the elderly patient. A careful physical examination, paying particular attention to possible disorders of extracranial structures, is indicated. A neurologic exam, including basic tests of higher cortical function, should be obtained. Important additional laboratory investigations include a complete blood count, erythrocyte sedimentation rate, and basic blood chemistries. Arterial blood gases should be obtained in patients who have pulmonary disease, a history suggestive of sleep apnea, or other disorders that may produce hypoxia and hypercarbia, resulting in vascular headache.(ABSTRACT TRUNCATED AT 250 WORDS)

This study investigates the relationship between nocturnal or morning headache and obstructive sleep apnea syndrome (sleep apnea). It is not known if headache of any type is more common in patients with sleep apnea than in other patients, but morning headache is a symptom of sleep apnea. A method is needed for identifying patients with chronic headache who might benefit from evaluation and treatment of sleep apnea. We performed a retrospective assessment of frequency of morning headache in patients grouped according to final diagnosis: sleep apnea (n = 72), periodic leg movements of sleep (n = 28), and psychophysiologic insomnia (n = 42). Prospective overnight sleep studies were obtained in a different group of 19 patients who presented for evaluation of headache. We selected certain patient characteristics as possibly indicative of sleep apnea-related headache. The retrospective study showed that 24% of patients with sleep apnea had frequent morning headache, which was not different from the other groups. In the separate group of 19 patients with chronic headache and suspected sleep disorder, 17 had sleep apnea. Nasal continuous positive airway pressure was prescribed to 14 patients. Marked improvement in headache occurred and persisted in 4 patients and moderate improvement in 3. Responders to therapy were more likely to have vascular headaches than mixed or tension headaches, more severe sleep apnea, and a nocturnal or morning timing to their headaches. However, there was large overlap in severity of sleep apnea and likelihood of response. We conclude that morning headache is not more common in sleep apnea than in other sleep disorders. However, over 30% of patients with chronic headache and other symptoms of sleep apnea have significant improvement in headache after treatment of sleep apnea.
