Based on self-rating questionnaire evaluation of symptoms of major affective disorder, 67% of patients who presented to a major sleep disorders center reported an episode of depression within the previous 5 years, and 26% described themselves as depressed at presentation. Furthermore, patients with sleep apnea, narcolepsy, or sleep-related periodic leg movements all averaged high rates of self-reported depressive symptomatology, which suggests that sleep disorders should be considered in the differential diagnosis of affective disorders, and vice versa. Change scores on the Profile of Mood States were obtained for four subgroups of patients who were undergoing conventional treatment. Significant improvement in scores was observed in obstructive sleep apneics treated surgically and in patients with sleep-related periodic leg movements placed on clonazepam, but not in narcoleptics placed on a stimulant or in insomniacs with chronic use of sedative-hypnotic drugs who were withdrawn from sleep medications. Differential improvement in POMS scores after treatment for different sleep disorders could mean that the relationship to mood disturbance differs for different sleep disorders.

Depression has been reported to be frequent in sleep apnea syndromes. In a sample of 25 consecutive male sleep apneics, 40% met Research Diagnostic Criteria for an affective disorder or for alcohol abuse. A multiple regression analysis indicated that 61% of the variance in depression ratings could be explained by four variables: age, REM activity, REM latency (square root), and presence or absence of antihypertensive medications (multiple R = 0.78). The use of these variables in a discriminant function analysis correctly predicted the membership of 68% of the sample in either a low or high depression group (kappa = 0.44; p less than .01). These findings are reviewed in relation to other research on age-related sleep changes and vulnerability to depression.

We performed screening polysomnography on 86 inpatients with affective disorders and found that 13 (15.1 per cent) had sleep apnea and one had nocturnal myoclonus. The apnea tended to be extremely mild, with an average of 27.8 episodes per patient and with a mean duration of 15.0 seconds. No clinically significant cardiac arrhythmia accompanied the apnea. The apnea was predominantly obstructive or mixed, not central. Only four patients (4.7 per cent) had apnea indices greater than five, and even here the total apnea was considered mild. Much of the apnea (68.3 per cent) occurred during rapid eye movement sleep. While there was no association of apnea with gender or with type of sleep-wake complaint, a significant relationship with age emerged. On the basis of these data, we suggest that routine polysomnographic screening for sleep apnea and nocturnal myoclonus in affective disorders is not indicated. On occasion, however, both an affective disorder and a sleep-apnea syndrome co-exist in the same patient. In such cases, the sleep-wake complaint is usually very prominent and/or long-standing in relation to other psychopathology and requires appropriate polysomnographic evaluation.

A group of 27 elderly patients with complaints of either chronic insomnia or excessive daytime sleepiness were studied in the Sleep Evaluation Center of Western Psychiatric Institute and Clinic during the period January 1977-June 1979. On the basis of anamnestic data from patients and bedroom partners, together with polysomnographic findings, sleep disturbances were classified according to the nosology of the Association of Sleep Disorders Centers. Of the 27 patients, 19 had disorders of initiating or maintaining sleep (DIMS), 7 had disorders of excessive somnolence (DOES), and 1 had parasomnia (episodic nocturnal wandering). Of the 19 DIMS patients, two-thirds had either a primary affective disorder (depression) or a persistent psychophysiologic disturbance. Of the 7 DOES patients, 6 had a primary sleep disorder such as a sleep apnea syndrome or narcolepsy-cataplexy. Additional electroencephalographic sleep data are presented on elderly patients with primary nonpsychotic depression. The latency of rapid eye movements (REM) in the depressed patients was shorter (p less than 0.05) than in patients with a persistent psychophysiologic disturbance. The percentage of REM sleep was significantly elevated (p less than 0.05) in the depressed group, and intermittent wakefulness was decreased (p less than 0.01). The causes of sleep disturbance in the elderly are both heterogeneous and complex. The need for accurate differential diagnosis and a multiaxial approach is stressed.

Sleep-wake habits and control of postural muscle tone were investigated by self-report questionnaire in 183 subjects considered to have the narcoleptic syndrome, 62 subjects with hypersomnia and 10 with obstructive sleep apnoea. Results were compared with those in a group of 188 control subjects with normal sleep wake habits. Excessive daytime sleepiness, determined by the Epworth Sleepiness Scale (ESS), was five times greater in the narcoleptic syndrome than in control subjects (score range 0-24, mean scores +/-SD 19.6+/-3.0; and 4.5+/-3.3 respectively; P<0.001). The propensity to cataplexy, as determined by a rating scale developed to estimate the likelihood of loss of postural tone in response to sudden emotional stimuli, including laughter, was 10 times greater in narcoleptic syndrome than in control subjects (postural atonia total score range 0-600; mean + SD 334+/-122 and 28+/-45, respectively; P<0.001). Narcoleptics had more disturbances of night sleep than controls with episodes of muscle jerking, sleep walking, sleep talking and sleep terrors, as well as sleep paralysis, and higher insomnia self-rating scores. Sleep latency from bedtime to sleep-onset time was shorter in narcoleptics than controls. The hypersomniac group of 62 subjects was heterogeneous. Subsequent investigation showed that 18 subjects (29%) had idiopathic hypersomnia, four (6%) 'incomplete' narcolepsy without cataplexy and 10 (16%) hypersomnia accompanying a mood disorder. The mean ESS scores in this group and in subjects with obstructive sleep apnoea were comparable to those of the narcoleptic syndrome subject group. Mean postural atonia scores were similar to those of control subjects.

Sleep apnea syndrome is a common, life-threatening disorder, causing significant physical, emotional, and social problems. The symptoms of obstructive sleep apnea syndrome can lead to an erroneous diagnosis of dysthymia. For patients with sleep apnea syndrome, standard antidepressant treatments may exacerbate the condition. DSM-IV's diagnostic model needs only a small change to allow consideration of sleep apnea syndrome as a cause of a mood disorder.

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.

The Japanese Society of Mood Disorders (JSMD) published the "Treatment Guideline II: Major Depressive Disorder, 2012 Ver. 1" on July 26, 2012. This guideline (GL) is the first one published by an academic society in Japan. Presently in Japan, many people have depressive symptoms, and the socioeconomic loss (suicide, absence from work, etc.) induced by this condition cannot be overlooked. Although the Japanese society, including mass media and psychiatrists, has attempted to solve this public problem, a solution has not been found. JSMD regarded diagnosis and psychiatric management of depression, among other factors, as the key to solving this problem. For example, patients who meet the DSM-IV major depressive disorder (MDD) criteria still have numerous subtypes, and they often have other psychiatric comorbidities that a diagnosis of MDD alone cannot detect. Although the process for differential diagnosis and treatment planning is indispensable, its methodology has not been necessarily shared even among psychiatrists until today. In this GL, considering the research evidence and its limitations, JSMD suggests necessary steps for appropriate information intake, diagnosis, therapeutic alliance formation, psychoeducation, and treatment modality choice in every phase (acute and continuation/maintenance). This GL also considers pharmaco-, psycho-, and electroconvulsive therapy for major depressive subtypes (mild, moderate/severe, and psychotic). Simultaneously, psychiatrists are required to be alert to the risk from diffuse and multiple prescription of benzodiazepine receptor agonists (dependence, deterioration of sleep apnea, cognitive decline, paradoxical reaction, etc.), especially barbiturates. This GL will be revised on the basis of public comments, including criticism. In the future, treatment GLs for comorbid patients, return-to-work cases, primary care physicians, psychiatric residents, and patients with depressions other than MDD (subthreshold depression, dysthymic disorder, and adaptation disorder) may be needed.

Sleep patterns share common pathways with nociceptive stimuli. Several important factors are reviewed in considering connections between sleep and pain. Causes for sleep fragmentation include sleep disordered breathing; abnormal leg movements, including restless legs syndrome and periodic limb movements; and underlying mood disorder, which may be exacerbated by physical symptoms. Identification and management of insomnia includes the definition of the condition, pharmacologic interventions, the role of circadian rhythms and clock adjustments, and the use of cognitive behavior therapy for insomnia.

Obstructive sleep apnea (OSA) may manifest in a number of ways from subtle intrusion into daily life to profound sleepiness, snoring, witnessed apneas and other classic symptoms. Although there is increasing evidence suggesting OSA can adversely affect health in a variety of ways, this disorder remains underdiagnosed. The most well-escribed health consequences of OSA relate to the cardiovascular system. Hypertension and arrhythmias have a strong association with OSA, and evidence suggests that treatment of OSA in patients with refractory hypertension and in patients planning cardioversion for atrial fibrillation may be of particularly importance. Significant associations between heart failure and OSA as well as complex sleep apnea have also been well-described. Cerebrovascular insult, impaired neurocognition, and poorly controlled mood disorder are also associated with in OSA. Therapy for OSA may ameliorate atherosclerotic progression and improve outcomes post-cerebrovascular accident (CVA). OSA should be considered in patients complaining of poor concentration at work, actual or near-miss motor vehicle accidents, and patients with severe sleepiness as a component of their co-morbid mood disorders. The metabolic impact of OSA has also been studied, particularly in relation to glucose homeostasis. Also of interest is the potential impact OSA has on lipid metabolism. The adverse effect untreated OSA has on glucose tolerance and lipid levels has led to the suggestion that OSA is yet another constituent of the metabolic syndrome. Some of these metabolic derangements may be related to the adverse effects untreated OSA has on hepatic health. The cardiovascular, neurocognitive, and metabolic manifestations of OSA can have a significant impact on patient health and quality of life. In many instances, evidence exists that therapy not only improves outcomes in general, but also modifies the severity of co-morbid disease. To mitigate the long-term sequela of this disease, providers should be aware of the subtle manifestations of OSA and order appropriate testing as necessary.
