A study was carried out in a rural area of Senegal to ascertain the pattern of mental disorders among patients presenting at primary health facilities. Among 545 children aged 5-15 years, attending health centres and posts, 17% were found to be suffering from some form of emotional problem, behaviour disturbance or neuro-psychiatric disorders. Using a 10-item screening questionnaire, it was shown that the symptoms "never plays with others' and "speech disturbance' were the strongest predictors of mental disorder among children. Among 933 adults, it was found that 16% reported more than seven symptoms commonly associated with psychiatric illness on a 24-item self-reporting questionnaire. The order in adults does not allow a precise estimate of morbidity to be made. Health workers diagnosed 9% of the patients as suffering from a mental health problem, usually in association with a physical problem. It was found that psychotic and suicidal symptoms (e.g. hallucinations, delusions) were more likely to be recognized by health workers as diagnostic of mental disorder, whereas psychophysiological symptoms (e.g. anorexia, insomnia, headache) and psychological symptoms (e.g. anxiety, depression) were less frequently recognized. The study supports the view that psychological symptoms and mental disorders occur relatively frequently among adults and children attending primary health facilities. Data allowing insight into the diagnostic sensitivity of primary health workers can provide a rational basis for planning training programmes in mental health.

This report represents the polysomnographic aspects of sleep and the psychological characteristics of a large series of patients with insomnia classified according to the diagnostic system of the Association of Sleep Disorders Centers. The findings for patients in the various diagnostic categories were compared to those of symptomatic patients with no objective findings. 9 specific diagnoses were made, but 4 diagnoses accounted for the majority of patients. The 4 most prevalent were psychophysiological disorders (15%), psychiatric disorders (17%), nocturnal myoclonus and restless legs (18%), and no objective findings (19%). Patients of a sleep disorders center are a select population and may not be representative of the general population of patients with insomnia complaints. The psychological characteristics of the different diagnostic groups were assessed by computing the number of elevations on the MMPI. Patients with a psychiatric diagnosis exhibited the highest number of MMPI elevations, as might be expected. Patients with nocturnal myoclonus had the lowest number of elevations. The other groups did not significantly differ from the group with no objective findings. Polysomnographic measures of sleep differed considerably among the diagnostic groups. The groups with medical disorders, respiratory impairment, atypical polysomnographic features, and nocturnal myoclonus had similar short sleep latencies to those of the group with no objective findings. With longer wake times before sleep and significantly different from patients with no objective findings were the psychophysiological disorder, psychiatric disorder and drug and alcohol groups. Patients with a circadian rhythm disturbance had the longest latencies.(ABSTRACT TRUNCATED AT 250 WORDS)

Over the past 20 yr, 40 controlled studies have been described concerning the effects of L-tryptophan on human sleepiness and/or sleep. The weight of evidence indicates that L-tryptophan in doses of 1 g or more produces an increase in rated subjective sleepiness and a decrease in sleep latency (time to sleep). There are less firm data suggesting that L-tryptophan may have additional effects such as decrease in total wakefulness and/or increase in sleep time. Best results (in terms of positive effects on sleep or sleepiness) have been found in subjects with mild insomnia, or in normal subjects reporting a longer-than-average sleep latency. Mixed or negative results occur in entirely normal subjects--who are not appropriate subjects since there is "no room for improvement". Mixed results are also reported in severe insomniacs and in patients with serious medical or psychiatric illness.

Polygraphic recordings of the sleep of patients complaining of insomnia has led to recognition of specific patterns of disturbed sleep corresponding to different etiologies of insomnia. This study presents results of polygraphic recordings of the sleep of 26 patients with chronic pain for which no physical cause can be found. All 26 also complained of insomnia. Sleep parameters of this group were compared with those to two other groups also complaining of insomnia: 12 patients whose disturbed sleep was judged secondary to psychiatric disorder, and 16 patients with the subjective complaint of insomnia in whom no objective evidence of sleep disturbance could be demonstrated. The three groups differed significantly in terms of their sleep parameters. The pain patients slept less than the subjective insomnia patients. The sleep disturbance of the psychiatric patients was more severe than that of the chronic patients. Several chronic pain patients showed evidence of nocturnal myoclonus; several also showed alpha rhythm intrusions into their sleeping electroencephalograms. The study verifies that chronic pain patients do experience significant sleep disturbance and raises several questions concerning relationships among chronic pain, sleep disturbance, and psychiatric illness, particularly depression.

According to sleep specialists, 30 to 80% of insomnia cases have a psychiatric cause. The author distinguishes between acute insomnia induced by acute psychiatric disorders and chronic insomnia associated with more or less permanent personality disturbances. This article reviews neurotic, depressive and maniac insomnia, insomnia of the alcoholic and of the toxicomaniac, insomnia during schizophrenia and chronic delusion. Insomnia may be the first symptom reported by the patient, hiding a subjacent psychiatric disorder. At the contrary, a short and insufficient sleep can only be discovered through a thorough investigation of the patient and questioning of his familiars.

The presenting symptom complex, diagnostic features, and therapeutic alternatives for obstructive and central sleep apnea are discussed in relation to two illustrative patients. Heavy snoring and restlessness during sleep in an obese individual, usually a male, may indicate obstructive apnea. Daytime hypersomnolence, intellectual deterioration, mental depression, impotence, cardiac arrhythmias, cor pulmonale, systemic hypertension, and erythrocytosis are the most common complications. Tracheostomy, the classic form of therapy, can be replaced by pharmacologic intervention in most patients. The clinical presentation of central apnea is less dramatic, but neurological and cardiac complications can occur. Therapy is less well established for this entity. Knowledge of the increased incidence of these disorders and awareness of more subtle complications indicate that sleep apnea should be placed in the differential diagnosis of pulmonary and systemic hypertension, hypersomnolence states, mental deterioration, psychiatric illness, and even insomnia.

We describe a new syndrome called "delayed sleep phase insomnia." Thirty of 450 patients seen for a primary insomniac complaint had the following characteristics: (1) chronic inability to fall asleep at a desired clock time; (2) when not on a strict schedule, the patients have a normal sleep pattern and after a sleep of normal length awaken spontaneously and feel refreshed; and (3) a long history of unsuccessful attempts to treat the problem. These patients were younger than the general insomniac population and as a group did not have a specific psychiatric disorder. Six patients' histories are described in detail, including the successful nonpharmacological chronotherapy regimen (resetting the patients' biological clock by progressive phase delay). Delayed sleep phase insomnia is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.

The effect of ageing on the sleep of insomniacs was studied by comparing objective insomnia characteristics from polygraphic recordings made during two successive nights in two groups of different ages : 14 patients aged 19 to 39 years (mean 31 years) and 11 aged 42 to 65 years (mean 50 years). All of them had severe insomnia causing them to request consultation for sleep disorders. Their only clinical symptom was chronic primary insomnia, persisting following withdrawal of hypnotics, no other physical (particularly no sleep apnea) or psychological disorder being present. Parameters studied during the first and the second night were the number and duration of intra-sleep awakenings, and the proportions of the sleep and wakefulness periods.

Neuroleptic withdrawal reactions have significant clinical and medicolegal implications for individuals with developmental disabilities. Behavioral deterioration following neuroleptic taper can represent (a) relapse of a mental illness, (b) and anticholinergic rebound reaction, (c) tardive akathisia, and (d) possibly a supersensitivity psychosis. Such reactions may preclude the discontinuation of neuroleptic drug therapy, even in the absence of a drug-responsive psychiatric illness. In this report, the case histories of two individuals who experienced a thioridazine (Mellaril) withdrawal-induced behavioral deterioration were presented. Both reactions were characterized by anxiety and insomnia, and the patients' symptoms were relieved by uncontrolled treatment with clonidine (Catapres) therapy. Evidence for adrenergic hyperactivity as a mediating event was presented.

There are currently three recognized menstrual-related sleep disorders: premenstrual insomnia, menopausal insomnia and premenstrual hypersomnia. Another category, premenstrual parasomnia (sleep behavior disorder), is now suggested. Case 1, a 17-year-old female, presented with a 6-year history of exclusively premenstrual sleep terrors and injurious sleep-walking that began 1 year after menarche. During the four nights preceding each menses, she would scream and run from her bed. There was no history of premenstrual syndrome. Neurological evaluations had been unrevealing, apart from mild mental retardation and attention deficit disorder; there was no psychiatric history. Polysomnography 3 days before the onset of menses confirmed the diagnosis of sleep-walking. Pharmacotherapies were not satisfactory, but self-hypnosis at bedtime was rapidly effective with benefit sustained at 2.5-year follow-up. Case 2, a 46-year-old woman without psychiatric disorder, presented with a 5-year history of sleep terrors and injurious sleep-walking that initially was not menstrually related, but beginning 8 months prior to referral, she developed an exclusively premenstrual parasomnia that, after polysomnography, was partially controlled with bedtime self-hypnosis and clonazepam, 0.25 mg.
