Very few epidemiological surveys have specifically studied relationships between sleep disturbances and psychiatric diseases. In this review, we preferred to use the classification proposed in 1979 by the Association of Sleep Disorders Centers. It includes four main categories: insomnias, excessive sleepiness, troubles of the wake/sleep schedule and parasomnias. Evaluating psychiatric disorders among general populations is easier owing to DSM III and DSM III-R criteria, but there are not equivalent criteria in evaluating sleep disorders. It is almost impossible to realize polysomnographic recordings in large samples, therefore sleep disorders are to be detected by questionnaires. It has been shown that there is a good correlation between self-reports and polysomnographic recordings among clinical and general samples. The prevalence of insomnia, defined as difficulties of initiating and maintaining sleep, is estimated between 9 and 31%. It is higher among women, elderly people, separated and divorced subjects, and low educational levels' groups. It has to be noticed that polysomnographic records of some subjective insomniacs are not different from those of good sleepers, sleep latency excepted. These subjective (and not objective) insomniacs have high scores in anxiety scale, depression scale, or psychologic distress. Insomnia is more frequently noted amongst subjects with psychiatric diagnoses, especially major depressive disorders and anxiety disorders. Depressive disorders are present in 21-40% of insomniacs versus 0-1% of non-insomniacs, and anxiety disorders in 13-24% of insomniacs versus 3-10% of non-insomniacs. In depressive disorders, sleep alterations are frequently noted: they are difficulties of initiating and maintaining sleep, decreasing proportion of slow-wave sleep, decreasing time of REM (rapid eye movement) sleep and REM sleep latency, and increasing density of REM sleep. Of these modifications, the last two ones seem to be specific for depression. The relationships between sleep, aging and depression are more complex than previously noted. For example, differences between depressed and non-depressed subjects depend on the age of the population. The prevalence of hypersomnia is lower than the insomnia's. It varies between 2 and 4%. It is more frequently noted among young people, and never married subjects. Two specific aetiologies must be looked for: sleep apnea syndrome and narcolepsy. These diagnoses are respectively found in 45% and 24% of hypersomniacs examined in American Sleep Centers. Hypersomnias are objectived by the Multiple Sleep Latency Test, which measures the physiologic sleep tendency.(ABSTRACT TRUNCATED AT 400 WORDS)

The study was carried out in the Family Planning Center of Sir Salimullah Medical College, Mitford Hospital and Family Planning Center of Dhaka Medical College Hospital, Dhaka. 100 sterilized women were selected randomly within 6 months of sterilization during the period of July 1991 to December 1991. They were interviewed by a questionnaire collecting information on sociodemographic parameters, sterilization, and life events. Depressive disorder was assessed by applying the DSM III-R criteria for Major Depressive Episode (MDE). Then the Hamilton Rating Scale for Depression (HRSD) was applied. 19 were suffering from depressive disorder (MDE). Of these, 3 were severe, 8 were moderate, and 8 were mild. Their ages ranged from 21 to 38 years. 42.11% of the depressive cases were in the 26-30 age group. 84% of both groups were either illiterate or had primary education, and 86% were housewives. 78% were urban and 22% were rural residents, respectively. 52% were in the low and 41% were in the middle income category. 35.8% of the nondepressive group had 4 children at the time of operation, while 36.93% of the depressive group had 6 children (p 0.05). Abdominal pain occurred in 23 instances, while only 2% had pain, swelling, and fever. 46 (56.79%) of the nondepressive group had experienced no momentous life events 1 year prior to the interview. In contrast, only 2 (10.54%) of the depressive group had not experienced such life events. Relationship problems in both the nondepressive and depressive groups featured with 24 (29.63%) and 12 (63.16%) cases, respectively, (p 0.05). 3 (15.79%) of the depressive group had past history of anxiety disorder and 2 (10.5%) had previous history of depressive disorder. On the basis of DSM III-R, 18 (94.74%) of the depressive group had mood disorders as the main symptom. 16 each had insomnia and fatigability. 12 (63.16%) of the depressives were retarded and 10 subjects contemplated suicide. HRSD further revealed that all depressive patients had anxiety, and only 2 were receiving antidepressants. Among all patients there were 5 cases of family history of schizophrenia, 2 cases of depressive disorders, and 1 case of bipolar mood disorder in first degree relatives.

The effects of a 15 day treatment with zolpidem (10 mg) and with flunitrazepam (1 mg) on Insomnia Disorders Related to Depressive Disorders (DSM-III-R) have been evaluated on 30 depressive in-patients (mean age 42.3 +/- 9.8). The trial has been carried out on double blind condition after 5 days of single blind placebo administration. Withdrawal effects have been evaluated in single blind condition on a 10 day period after drugs discontinuation. Patient's diagnosis was Major Depression or Dysthymia according to DSM-III-R; inclusion criteria were insomnia (total sleep time < or = 6 h, sleep latency > or = 30 min, wake after sleep onset > or = 30 min, No of awakenings > or = 3) refractory to clomipramine administration at constant dose (75-150 mg/day among patients). Both drugs have been followed by a rapid, significant diminution of insomnia as demonstrated by significant changes at Stanford Sleepiness Scale and Saint Mary Hospital Sleep Questionnaire and by a significant reduction of HDRS total scores. No clinical phenomena of rebound insomnia were detected after zolpidem and flunitrazepam withdrawal. Drug discontinuation however was followed by the slow increase of the score on insomnia items, approximating basal values at the end of the 10 day period after zolpidem and flunitrazepam withdrawal. A parallel increase of HDRS total score was also detected; HDRS changes were mainly due to the increase of the items anxiety somatic, general somatic symptoms, gastrointestinal somatic symptoms, hypochondriasis. The study confirms the therapeutic efficacy of zolpidem and of flunitrazepam in the treatment of insomnia resistant to antidepressant drugs in depressed patients. They also suggest that early drug discontinuation is frequently associated with clinical relapse of insomnia and of several other symptoms correlated with the affective pathology.

The co-occurrence of insomnia and mental disorders constitutes the most prevalent diagnosis pattern found in sleep disorder clinics. Yet, there remains a paucity of epidemiological information regarding comorbidity of mental disorders and sleep disorder symptomatology in the general population. The present study showed results based on a large representative French cohort (n = 5,622; 80.7% of the contacted stratified sample). A total of 997 (17.7%) individuals with insomnia complaints were identified and divided into six diagnostic categories: (1) Insomnia related to a Depressive Disorder; (2) Insomnia related to an Anxiety Disorder; (3) Depressive Disorder accompanied by insomnia symptomatology; (4) Anxiety Disorder accompanied by insomnia symptomatology; (5) Primary Insomnia; and (6) isolated insomnia symptomatology. Telephone interviews were conducted using the Sleep-Eval System. Subjects with insomnia related to a Mental Disorder have a longer history of insomnia complaints and are usually younger than those with Depressive or Anxiety Disorders accompanied by insomnia symptoms. Subjects with Insomnia related to a Depressive Disorder experienced more repercussions than any other group. A surprisingly high percentage of individuals with depressive symptomatology had sought independent medical treatment specifically for their sleep problems, which raises the unsettling possibility that many cases of depression go undetected by the general medical community. The distinct predictability of commonly undiagnosed depression leading to chronic depression speaks directly to the imperative that physicians receive additional training in this area of community mental health.

Patients suffering from Parkinson's disease (PD) often report about sleep disorders and excessive daytime sleepiness. To some extent, motor disabilities or neural degeneration of sleep modulating structures may be responsible for these effects. Depressive disorders also contribute to the occurrence of insomnia and daytime sleepiness. Nevertheless, dopaminergic, anticholinergic, and other drugs used in PD have a great impact on sleep/wakefulness mechanisms. They may indirectly improve or worsen sleep by changing motor symptoms such as akinesia, hyperkinesia, or tremor. Although their is only little information on the complex regulation of vigilance, it is well known that monoaminergic and cholinergic drugs could influence it directly. Data from animal experiments and clinical experiences led to the hypothesis of a biphasic influence on sleep by dopaminergic substances: small doses of L-Dopa e. g. appear to improve sleep whilst higher doses led to insomnia. Different dopaminergic receptor types or changes in receptor sensitivity may explain these phenomena. Dopaminergic and anticholinergic drugs suppress REM sleep. Recently, initial data on 'sleep attacks' after pramipexole or ropinirole treatment were published. Our preliminary results using 24 h polygraphic recordings showed excessive daytime sleepiness in patients taking ropinirole and L-Dopa which disappeared when changed to ropinirole monotherapy. Sleepiness did never appear as an irresistible attack. Current hypotheses on this topic are reviewed.

Depressive disorders are among the most frequent psychiatric diseases in the Western world with prevalence numbers between 9% and 18%. They are characterized by depressed mood, a diminished interest in pleasurable activities, feelings of worthlessness or inappropriate guilt, decrease in appetite and libido, insomnia, and recurrent thoughts of death or suicide. Among other findings, reduced activity of monoaminergic neurotransmission has been postulated to play a role in the pathogenesis of depression. Consistent with this hypothesis, most antidepressive drugs exert their action by elevating the concentration of monoamines in the synaptic cleft. However, it is not the enhancement of monoaminergic signaling per se, but rather long-term, adaptive changes that may underlie the therapeutic effect. These include functional and structural changes that are discussed later. In addition, in the last years, evidence has emerged that remissions induced in patients using lithium or electroconvulsive therapy are accompanied by structural changes in neuronal networks thereby affecting synaptic plasticity in various regions of the brain.

The authors examined the prevalence, characteristics, and correlates of depressive disorder among medical inpatients age 60 or over at a private teaching hospital. Seventy-six of 129 patients admitted to the general medicine and cardiology services at Duke University Hospital were screened for depressive disorder using DSM-III-R criteria. Depressive disorders were diagnosed in 34.2% of patients: major depression in 13.2%, adjustment disorder in 11.8%, depression not otherwise specified in 5.3%, organic mood disorder in 1.3%, and uncomplicated bereavement in 2.6%. Of patients with major depression, all had symptoms of mild-to-moderate severity. The most common presenting symptoms were insomnia, psychomotor agitation, difficulty concentrating, and loss of energy. Depression was more prevalent among women, general medicine patients, staff (vs. private) patients, and those who were functionally disabled or had multiple serious medical conditions. When other patient characteristics were controlled, however, only health factors were independently associated with depression.

Depressive disorders are common among young people and can decrease social competences and thus the quality of life. There is a relationship between the occurrence of depressive disorders and insomnia. The aim of the study was to determine the prevalence of insomnia and depressive behavior and assess the relationship between these among participants of the Pol'and'Rock Festival, Kostrzyn, Poland 2019. The study used the Athens Insomnia Scale (AIS) and the Beck Inventory II Scale (BDI-II). The study group consisted of 923 people, with the majority of women (n = 500; 54.2%). A total of 297 persons (32.2%) reported varying severity of depressive symptoms. Insomnia was observed in 261 (28.28%) respondents. Sleeping disturbances were observed more frequently in females. Persons with insomnia had a significantly higher BDI-II score. A strong positive correlation (r = 0.65) between the number of points obtained on the Beck and AIS scales was observed. Insomnia and depressive behavior are prevalent in the Polish population. Due to long-term social and economic consequences, special attention should be paid to the prevention, early detection and treatment of both disorders.
