One hundred ten patients with alcohol dependence and 56 psychiatric patients with either senile dementia, amphetamine psychosis, epilepsy or chronic schizophrenia were investigated with a CT scan of the brain. The maximum width of the 3rd ventricle was measured, and the presence/absence of enlargement of the lateral ventricle and of atrophy of the frontal lobe was determined independently by 3 physicians. The width of the 3rd ventricle in alcoholic and the other patients examined was gradually enlarged with aging, and the width in these patients was significantly larger than that in the age-matched control patients who were selected from the patients with amphetamine psychosis, epilepsy or schizophrenia. The enlargement of the lateral ventricles observed in the alcoholic patients always accompanied the enlargement of the 3rd ventricle, but not vice versa. The alcoholic patients with frontal lobe atrophy showed a higher incidence of withdrawal delirium than the patients without atrophy. These findings suggest that the chronic intake of alcohol might affect primarily the area around the 3rd ventricle, resulting in enlargement of this ventricle and consequential enlargement of the lateral ventricles and also that the alcoholic patients with frontal lobe atrophy could have a high risk for a manifestation of alcoholic withdrawal delirium.

In 1977 a questionnaire was sent to all psychiatric departments in the Nordic countries: Sweden, Norway, Denmark, Finland and Iceland, concerning indications for electroconvulsive therapy (ECT) and the use of unilateral and bilateral treatment, respectively. The inquiry was repeated in 1987 and the answers compared with those obtained in 1977. In addition, the answers from Denmark were compared with previously performed inquiries. The use of exclusively unilateral treatment (U) and of both unilateral and bilateral treatment (UB) has increased in most of the countries and exclusively bilateral treatment (B) has decreased drastically. In Denmark the situation has not changed for ECT in endogenous depression and acute delirium, and the use in reactive psychosis, mania and schizophrenia decreased somewhat during the 1970s and then again stabilized or increased during the 1980s. Nearly all departments in the Nordic countries used ECT in endogenous depression in 1977 and were still doing it in 1987. In mania, about 50% of all departments have found ECT indicated occasionally or exceptionally both in 1977 and 1987. Manic-depressive mixed states have been regarded as an indication in somewhat more than two thirds of departments, increasing during the period. The use of ECT in schizophrenia has been rare and somewhat decreasing, but still about half of the departments apply it once in a while. In reactive psychosis the use of ECT decreased slightly, but in 1987 it was still in use for this indication in about 50% of all departments. In acute delirium there has been an overall increase in the use of ECT.(ABSTRACT TRUNCATED AT 250 WORDS)

Over the past several years, research has demonstrated that the excitatory amino acids serve as the major excitatory neurotransmitters in cerebral cortex and hippocampus. Neurons that contain excitatory amino acids play crucial roles in neuropsychological functioning, learning, and memory. In addition, these neurons exert descending control over subcortical structures that is behaviorally antagonistic to the effects mediated by the ascending dopaminergic system. Disturbances of excitatory amino acid systems may contribute to the pathogenesis of schizophrenia and to other neuropsychiatric syndromes associated with delirium or dementia.

The American Psychiatric Association established the Task Force on Quantitative Electrophysiological Assessment in May 1989 to consider several questions of interest to psychiatrists. From the inception of techniques for quantitative electroencephalography (qEEG), the possibility was raised that it would substantially assist in the diagnosis of brain disorders. However, controversy exists over the scientific basis for such approaches and the training necessary for interpretation of computerized records. The task force's charge was to report 1) the present state of scientific knowledge about qEEG, 2) the role of qEEG in clinical psychiatric practice at the present time, 3) the training necessary for the use of qEEG techniques, and 4) the possible future of the technique in the study of mental disorders. The task force concluded that qEEG is particularly useful for the detection of abnormalities in slow waves, which are a feature of delirium, dementia, intoxication, and other syndromes involving gross CNS dysfunction. The ability of qEEG to help in the diagnosis of other disorders, such as schizophrenia or depression, is not yet established. Clinical replications and sharing of normative and patient data bases are necessary for the advancement of this field. Proper use of this technique requires extensive training in a center experienced in its use. Standards for training and for using the technology in psychiatry are urgently needed. This report was approved by the Board of Trustees in December 1990.

The clinicogenealogical method using a genetico-mathematic analysis was employed to examine 50 probands with sluggish hypochondriac schizophrenia (126 relatives of the first degree kinship). A study was made of the structure of familial accumulation of polar hypochondriac conditions (in continuum) of the varieties of sluggish schizophrenia: senestohypochondrias (25 families of probands) and neurotic hypochondrias (25 families of probands). The clinical polymorphism of sluggish hypochondriac schizophrenia correlated with the differences in accumulation, mainly by varieties of sluggish schizophrenia and personality abnormalities. It is concluded that analysis of the structure of familial accumulation in non-delirious hypochondriac conditions favours their typological differentiation, thereby enhancing the reliability of the clinical systematization.

Based on psychopathological and clinicocatamnestic studies made in 96 patients suffering from schizophrenia associated with obsessions running mainly an attack-like course the psychopathological characteristics of obsessions were specified and their relation to other psychopathological disorders was determined. In part of cases, obsession underwent qualitative changes acquiring the character of disturbances similar to value judgements, delirium and catatonic stereotypies. The typology of obsessions associated with schizophrenia was elaborated; two types of obsessions were distinguished: obsessions with goal-oriented protection measures and obsessions with the development of disturbances superficially similar to catatonic stereotypies. Obsessions and their course were found to be related to the degree of personality changes.

Based on clinico-catamnestic studies conducted in 50 patients with recurrent ("schizoaffective") schizophrenia 2 main types of an unfavourable disease course were distinguished: "stationary" (28 patients) and "labile-continual" (22 patients). The first variant was characterized by long and monotonous persistence of uniform affective delirious symptoms. The second variant was characterized by complete lack of any stability of the condition associated with permanent changing of polar affects and respective hallucinative delirious structures. Pronounced and reduced patterns of the disease course were distinguished in both variants. Clinical characteristics of the variants are provided, and ways by which they are formed are depicted. A number of theoretical problems, especially those concerned with the reliability of criteria for interrelations between the status and the disease course in the diagnosis and individual prognosis of the disease development are discussed.

Delirium, an acute confusional state, is an organic brain syndrome that manifests deficits in attention, irrelevant or rambling speech, and other cognitive deficits. Its symptoms often fluctuate over the course of the day, and patients may be hyperactive--for example, restless and screaming--or hypoactive--for example, quiet, inactive, and stuporous. Occurring in approximately 20% of hospitalized elderly patients, delirium is the most common psychiatric syndrome in acutely ill general medical and surgical patients. Fifteen to 30% of delirious patients expire, and others are prone to a variety of complications: falls, pressure ulcers, oversedation, dehydration, and others. Almost any acute illness can cause delirium in the elderly, but the most common offenders are acute infections and drugs. Many patients have a pre-existing dementia. The first step in arriving at a correct diagnosis is to distinguish delirium from other psychiatric syndromes that can cause confusion, such as dementia, depression, schizophrenia, and mania. Once delirium is established, a comprehensive general examination and a mental status examination is required. Routine laboratory and radiologic tests are directed at the common metabolic and infectious disorders that precipitate delirium. Treatment is directed at the underlying acute illness. In all patients, it is important (1) to treat the underlying acute illness, (2) to provide appropriate fluid and electrolytes, (3) to discontinue any unnecessary drugs, and (4) to allay the patient's fear and agitation through the use of simple, repetitive instructions, orientation cues, and by limiting the use of physical restraints. If psychotropic medications are needed to treat psychotic symptoms, to prevent patients from harming themselves or others, or to facilitate necessary diagnostic and therapeutic interventions, then haloperidol is the drug of choice in most instances. Drugs with anticholinergic properties should be avoided.

In a long-term psychiatric setting, self-induced water intoxication may be a life-threatening situation. At first glance, the symptoms or behaviors of self-induced water intoxication are similar to schizophrenia, i.e., inappropriate behavior, delusions, hallucinations, confusion, and disorientation. In some cases, the symptoms of water intoxication mimic schizophrenia and thus, are disguised as a part of the psychoses. Affected individuals develop polydipsia, which is accompanied by overhydration and dilutional hyponatremia. If untreated, the symptoms may progress from mild confusion to acute delirium, seizures, coma, or death (Ripley, Millson, & Koczapski, 1989). Under normal circumstances there is a delicate balance of water requirement and water intake. If the balance of water is altered, electrolyte imbalance can occur. The recognition of water intoxication or self-induced water intoxication and psychosis among chronic, institutionalized patients may prevent their death or the development of neurological damage (Arieff, 1985). Because self-induced water intoxication often goes unrecognized in its early stages and may have irreversible or fatal complications, early detection is crucial. This article will discuss the etiology, nursing assessment, and interventions associated with patients suffering from self-induced water intoxication.

Two cases of electroconvulsive therapy (ECT) in adolescence are presented and the literature on the use of ECT in childhood and adolescence is reviewed. ECT was effective in children and adolescents with bipolar disorder and depression. Inadequate information exists to make a judgment regarding schizophrenia, delirium, and anorexia nervosa. ECT is not effective in autism and chronic organic brain syndromes. Complications cited include organicity and seizures in the period immediately after ECT, anxiety reactions, and disinhibition. Long-term memory deficit or cognitive impairment has not been found, although further research to rule out residual impairment is needed.
