A 26 yr old puerperal female with Hallermann-Streiff syndrome developed serious obstructive sleep apnoea syndrome during pregnancy. She underwent an elective Caesarean section delivery, but ending the pregnancy did not improve her clinical symptoms. By treating her with nasal continuous positive airway pressure, a worsening of her headaches and glaucoma was prevented. The administration of acetazolamide controlled all of her symptoms. Treatment with nasal ventilation is the best initial approach. It is also important to assure normal oxygenation before pregnancy since the foetus may suffer from the severe deprivation that may occur in these patients.

Over the past two to three decades, sleep medicine has emerged as an important discipline as it strives to meet the challenges of some of the most prevalent disorders among humans. Among the 110 disorders listed in the International Classification of Sleep Disorders, two of the most prevalent and treatable have only recently begun to receive significant attention: sleep apnea and restless legs syndrome with sleep-related periodic limb movements disorder. It is becoming clear that the sleep disruption caused by such disorders has ramifications beyond the usually associated daytime sleepiness, and may include: exacerbation of seizures, headaches, short-term memory deficits, and other cognitive problems. Sleep apnea has also been correlated with hypertension and cardiovascular/cerebrovascular disease. Animal studies have taken this one step further by demonstrating that total sleep deprivation is consistently fatal, usually within 1 month, although the precise mechanism remains to be discovered. The most compelling finding in the animal studies is that "rescuing" the animals with sleep, before the irreversible stage, is associated with rebound amounts of deep sleep and rapid eye movement (REM) sleep ("dream sleep"). This same response is seen after initiating treatment of sleep apnea with nasal continuous positive airway pressure (CPAP), and can also occur in patients with other sleep disorders in response to particular medications, such as valproate or gabapentin.

Sleep apnea syndrome is a recognized manifestation of Arnold-Chiari malformation that almost invariably has been described in association with other neurological findings. We report a 39-year-old man who presented with severe daytime hypersomnolence. A detailed neurological examination was completely normal. Polysomnography revealed moderately severe mixed central and obstructive sleep apnea and hypopnea with persistence of central apnea and hypersomnolence despite nasal continuous positive airway pressure therapy. A history of severe headaches precipitated by sustained laughter prompted the consideration of an Arnold-Chiari malformation (ACM). A type I ACM with no evidence of syringomyelia or hydrocephalus was confirmed by MRI and successfully decompressed by suboccipital craniotomy and upper cervical laminectomies. Post-operatively the patient's headaches and hypersomnolence disappeared and a repeat polysomnography showed marked improvement in the sleep-disordered breathing. Physicians should be aware that severe sleep- disordered breathing may be the initial and sole presenting feature of Arnold-Chiari malformation.

The multiple chemical sensitivities syndrome (MCS) and other chronic syndromes causing fatigue, headache and other protean CNS symptoms without observable signs, are proposed to result from hypoxia/hypercapnia (H/H) due to disturbed breathing. The concept is explained in terms of sleep apnea (SA), although H/H could result from causes other than SA. Reasons for considering this etiologic linkage are as follows: 1. MCS symptoms resemble those of SA. 2. The only physical signs associated with MCS (upper airway inflammation and obstruction) can aggravate SA. 3. The only neuropsychiatric finding common among MCS symptomatics, reduced verbal recall, is associated with SA. 4. Many MCS symptomatics attribute onset of their condition to a pesticide or solvent exposure. Solvent neurotoxicity may cause cacosmia, a symptom of MCS and SA. 5. Improved upper airway patency, a first-line therapy in SA, may improve symptoms in some MCS-like conditions. Implications for diagnosis and treatment of MCS are discussed.

Obstructive sleep apnea (OSA) has many consequences. There is an independent association between OSA and hypertension. The Sleep Heart Health Study reported that hypertension prevalence increased as sleep disordered breathing severity increased. The Nurses' Health Study noted an age-adjusted relative risk of cardiovascular events of 1.46 for occasional snorers and 2.02 for regular snorers, and a risk of stroke of 1.60 for occasional snorers and 1.88 for regular snorers. Sleep apnea is also associated with pulmonary hypertension, neurocognitive effects, depressed quality of life, motor vehicle accidents, awakening headache, childhood growth interruption, pregnancy-induced hypertension, fetal growth retardation, and disruption of the patients' bed-partners' sleep quality. Further research will examine the possibility of causality, pathophysiologic mechanisms, and outcomes of therapeutic interventions for OSA on the many consequences of OSA.

Approximately 10% of women and 5% of men at age 70 experience severe recurrent or constant headaches. Severe headache presenting for the first time in a patient over age 50 is unusual and requires a thorough medical and neurologic examination. Primary headache etiologies in older patients include migraine, tension-type, cluster, and the rare hypnic headache. For all of these, effective pain control includes pharmacologic and nonpharmacologic interventions. Secondary etiologies include temporal arteritis, medication-induced headache, cerebrovascular or cardiac ischemia, and intracranial hemorrhage or tumors. Head pain may also be cervicogenic or related to glaucoma or sleep apnea. In secondary cases, pain management is specific to treatment of the underlying structural or systemic disease.

The relationship between sleep and headache has great individual variation. Headaches that arise primarily out of sleep have a broader differential diagnosis than random headaches, and a specific cause should be identified, if possible. Sleep apnea can trigger or cause sleep-related headaches. Hypnic headache is one of a few specific, uncommon, idiopathic sleep-related headache syndromes. Treatment of sleep-related headache includes treating the underlying cause, such as sleep apnea, and prescribing medications usually used for headache as well as medications for sleep disorders.

Seventy-eight workers, drawn from a population of 1502 presumably healthy working men who were interviewed about sleep habits and sleep disorders, underwent polygraphic recordings for at least 1 night. A significant association was found between the complaint of excessive daytime sleepiness and the incidence of sleep apnea. Workers with more than 10 apneas per hour of sleep complained significantly more about loud snoring, hypermotility in sleep, and frequent headaches. They had significantly more ENT findings and hypertension.

There is still a controversy regarding the relationship between sleep apnoea syndrome and headaches, especially morning headaches. Our objectives were: (i) to compare the prevalence and the clinical data of headaches in sleep apnoea syndrome (SAS) and control (snorers) groups defined by polysomnographic recording; (ii) to analyse the clinical improvement of headaches with appropriate treatment; and (iii) to correlate headaches with mood disorders, and nocturnal respiratory and architectural sleep parameters in order to understand the underlying pathophysiological mechanisms. This is a prospective study of 324 consecutive patients referred to our sleep centre for snoring. Of these, 312 patients who underwent sleep polysomnography were finally included. Patients and controls were interviewed about their medical past, headache history and clinical characteristics, their daytime sleepiness (Epworth's sleepiness scale) and their mood disorders (Zerssen's scale). Follow-up of patients with headaches (SAS and control groups), treated or not, was also assessed. According to our definition of SAS, patients were dissociated in SAS (n=164) and snorers (n=148). Fifty-three SAS patients had headaches, of whom 58.5% (n=30) suffered from morning headaches. However, there was no statistical difference between the two groups concerning the prevalence and the clinical characteristics of headaches. In addition, headaches and morning headaches were not correlated with nocturnal respiratory and architectural sleep parameters, nor with excessive daytime sleepiness, but were strongly correlated with mood disorders. In 36 SAS patients, headaches improved under treatment, but this was not statistically different from what was found among untreated snorers. Headaches and morning headaches are common in patients with SAS but may be considered as a non-specific symptom. The underlying mechanisms are not fully elucidated but depression could play an important role. Despite this absence of specificity, the treatment of SAS, especially nasal continuous positive airway pressure, leads to an improvement in headaches in several cases.

The sleep apnea syndrome (SAS), which is defined by more than 5 apneas or hypopneas per hour of sleep (9), is quite a frequent affection which concerns 1.4 to 10% of general population (1.7). The major daytime complaints of the SAS are daytime sleepiness, memory and attention disorders, headaches and asthenia especially in the morning, and sexual impotence (9). The nocturnal manifestations are dominated by sonorous and generally long standing snoring, increased by dorsal decubitus and intake of alcohol, with repeated interruptions by respiratory arrests. These manifestations are always noted but rarely spontaneously reported. The sleep, non refreshing, is agitated and perturbed by numerous awakenings. The findings of the clinical examination are poor: obesity is found in 2/3 of the cases and arterial hypertension in 1/2 of the cases (20). Polygraphic recording during sleep only permits an absolute diagnosis. This frequent affection is a real problem of public health because of its numerous complications (3, 10, 12, 13, 18, 21). Symptoms of depression are often found when a patient with a SAS is examined and conversely, symptoms which evoke a SAS can be found in the clinical examination of depressed patients. We decided so to study the thymic and anxious status of 24 patients investigated for a SAS and submitted to a polygraphic recording during sleep. Four clinical parameters were studied: DSM III-R diagnosis criteria, Montgomery and Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HARS) and thymasthenia rating scale of Lecrubier, Payan and Puech. We also reported Total Sleep Time (TST = 6.5 +/- 1.5), Apnea Hypopnea Index (AHI = 26.7 +/- 21.6), number (2.1 +/- 2.8/h) and duration (174.2 +/- 150.8 s/h) of hypoxic events. Results showed that among 24 patients, 8 were depressed according to DSM III-R diagnosis criteria and had MADRS > 25, 22 were anxious, 11 had a major anxiety (HARS > 15) and 15 presented thymasthenia (SET > 15). Significative correlations existed between anxiety and depression (r = 0.82; p < 0.0001), depression and thymasthenia (r = 0.77; p < 0.0001) and thymasthenia and anxiety (r = 0.75; p < 0.0001). Among the 8 depressed patients a correlation existed between AHI and depression (r = 0.72; p = 0.04), but no correlation was found between depression and hypoxic events. These results were comparable to those of Guilleminault (10), Reynolds (21), Kales (12), Bliwise (3), Klonoff (13) and Millman (18) who studied relations between SAS and depression. The evaluation of thymasthenia gave a more precise typology of the depressive state associated to SAS: the type of the mood disorder is more "blunted" and "anhedonic" than "sorrowful", particularly characterised by asthenia, lack of energy, reduction of interests (leisures, libido, work), loss of initiative, difficulties to organise tasks, fall of performances and reduction of pleasure usually felt in pleasant events (15). The physic symptomatology dominated the psychic one. The sleep disorganization, more than metabolic consequences of apneas, could be involved in this associated depressive state. Other neuropsychiatric troubles can be associated to the SAS. In fact, cognitive troubles (2, 8, 14, 16, 19, 22, 24) and personality disorders (12, 18) have been described. Our data confirm previous observations suggesting a frequent association between SAS, depression, fatigue and anxiety. Clinicians should consequently be aware that a depression with severe complaints of fatigue should deserve an investigation oriented towards SAS. Conversely, when a SAS is diagnosed, it is necessary to look for a possible depression in order to set up the most appropriate treatment. The frequency of SAS, like depression's one, increases with age. Prescription and consummation of sedative psychotropic drugs increase too with age. Since respiratory depressant effects of these drugs have been clearly demonstrated, it is important to evoke SAS when depressive and/or anxious states are diagnosed and not to aggravate it. An efficacious treatment of SAS can also cure the associated depressive state, but this one can persist. It is necessary, in this case, to select a non sedative antidepressant.
