The perceptional characteristics of hallucinatory events and the phenomenal forms of artificially produced hallucinations were studied on a total of 210 patients (144 patients with delirium tremens, alcoholic hallucinosis, abstention from alcoholic beverages freedom from abstinence symptoms and 66 subjects with schizophrenia, symptomatic epilepsy, general paralysis, neuroses, and conditions of intoxication). The results of our studies show that Liepmann's test may be used to reliably diagnose genuine hallucinoses. They are usually preceded by a number of different stages, these being the stages of stability of development and full development of prehallucinatory phenomena, simultaneous and suggestive periods of geniune hallucinations. Liepmann's test is specifically distinctive of psychopathological disorders associated with delirium tremens.

Oral administration of ET-495 was found to cause worsening of psychiatric status in 4 out of 7 schizophrenic patients, and to induce a paranoid state and a syndrome of auditory hallucinosis in 2 non-schizophrenics. These observations were compatible with the hypothesized role of dopamine in schizophrenia. However, these psychotogenic effects were far less dramatic than those noted in other studies with amphetamine, methylphenidate or L-Dopa. Possible explanations for this differing psychotogenic potency of receptor stimulators versus presynaptic agonists are presented. Intravenous ET-495 and apomorphine did not show psychotogenic effects.

Based on clinico-psychopathological and catamnestic examinations of 118 patients, the authors studied and compared the characteristics of the clinical picture, dynamics and outcome of schizophrenia and acute alcoholic hallucinosis associated with delirious, hallucinatory and pseudohallucinatory disorders of homosexual nature. Base the prognostic importance of psychopathological phenomena of homosexual nature in patients with schizophrenia and acute alcoholic hallucinosis. The rise in the clinical picture of schizophrenia and acute alcoholic hallucinosis of the portion of psychopathological phenomena of homosexual nature, not entering the number of permanent and necessary manifestations of the indicated clinico-nosological forms of psychoses, occurring, however, in the rudimentary form may be viewed as a manifestation of pathomorphism. It has been demonstrated that if schizophrenia and acute alcoholic hallucinosis are associated with psychopathological phenomena of homosexual nature, this may enhance the risk of the committing by the patients of grave aggressive and suicidal actions.

Altogether 61 patients with schizophrenia manifesting for the first time by hallucinatory disorders, playing the leading part in the psychosis picture were examined. 3 typological varieties of acute hallucinatory conditions were described, their comparative characteristics were provided. It has been demonstrated that acute hallucinosis occurred during the disease in different clinical forms: so-called schizophrenic reactions in latent disease (variant I), phases and attacks within the framework of a well-defined attack-like (shift-like) and similar to a recurrent (variant and an attack-like progredient course, approximating to a continuous one (variant III). Problems of a comparative assessment of the further disease course manifesting by different conditions of acute hallucinosis and adequacy of the use of the elaborated typology thereof for prediction and choice of therapy are discussed.

A first comprehensive description of the clinical features of patients with the rare diagnosis of organic hallucinosis (OH) is presented, based on information from 11 OH patients among 14,889 patients who presented for evaluation over a 5-year period at our institution. This characterization is of particular current relevance to diagnosticians and clinicians because of the proposed major changes in the diagnostic system for OH in the upcoming DSM-IV and because of the virtual total lack of published information concerning this syndrome. This description includes a listing of the prevalence and mean severity of each symptom. The severity of the symptoms of OH are then compared with those of its crude "functional" equivalent of schizophrenia to determine which symptoms distinguish between these categories. Associated factors are also presented concerning demographics, modes of treatment, level of functioning, and current physical problems associated with OH.

The frequency of schizophrenic first-rank symptoms (FRS) were investigated in 1698 patients with an organic mental disorder (OMD) according to Schneider's and DSM-III criteria: 7% of the patients with OMD had FRS, compared with 47% of schizophrenic patients. However, the frequency of FRS depends on the state of consciousness and on the aetiology of the OMD: 20% of the patients with clear consciousness had FRS, but only 1.5% of those with clouded consciousness. In cases of some aetiologically defined groups of OMD, such as post-ictal epileptic psychoses or alcoholic hallucinosis, the frequency of FRS is similar to that in cases of schizophrenia. FRS appear to be psychotic reaction patterns whose substrate-related basis extends across the whole spectrum of endogenous and exogenous psychoses.

A review of the literature on HIV and psychiatry thus far has revealed 13 cases of HIV infection presenting as psychosis. We argue that these cases could in fact represent either coincidental schizophrenia or bipolar disorder and HIV infection or HIV-related organic hallucinosis, delusional or affective syndromes with or without associated dementia (AIDS-dementia complex). The use of the term psychosis in describing AIDS-related behavioral syndromes is misleading, and should be replaced when possible by specific DSM-III-R categories.

The authors studied the characteristics of the hereditary aggravation in probands with schizophrenia first manifested with acute delirious or acute verbal hallucinosis. They also considered the incidence of manifest and latent forms of schizophrenia and the rate of personality anomalies in families of probands with the differentiation of schizoid anomalies by the predominance of sthenic and asthenic features. The frequency of coincidence of the patterns of schizophrenic process among relatives was determined and the data obtained were compared with those in probands from each group. The comparative analysis has shown that the familial background of the studied group of probands reflects the following regularities characteristic of schizophrenia; an increase in the frequency of psychoses of the schizophrenic spectrum as against that in the general population, accumulation of homonomous types of the schizophrenia course and the presence in relatives of abnormalities of the schizophrenic nature. This justifies the referral of the studied forms of psychoses to schizophrenic diseases.

The clinical presentation of three patients with meningiomas at different frontal sites is described. They had been ill for 3, 25, and 43 years before the tumour was demonstrated radiologically. Apathy, incontinence, dementia, and fits were seen in association with middle and superior frontal lesions, and may be mistaken for symptoms of involutional depression or presenile cerebral atrophy. In contrast, excitement and hallucinosis were seen in association with a basal frontal lesion, and may mimic psychotic syndromes like hypomania and schizophrenia, particularly if the tumour encroaches on the third ventricle and adjacent structures. Irreversible loss of myelin and axons in the frontal areas of brain surrounding the tumour may have contributed to the clinical picture of the syndrome shown by these patients.

The psychiatric manifestations of Huntington's Disease (HD) include dementia, irritability and apathy, a major affective syndrome, and hallucinosis. The theoretical and practical utility of chorea as a focus of research interest in HD is questioned, whereas the data reviewed suggest that assessments of cognition, functional capacity and motor impairment are better correlated neuropathologically, and are better indicators of disease severity and progress than chorea. The high incidence of major affective disorders on modified DSM III criteria among HD patients (41 per cent) may be explained either as a manifestation of genetic heterogeneity within the HD phenotype or on the basis of genetic linkage between HD and manic depressive illness (MDI). This is supported by the high coincidence of HD and MDI (20 out of 23) among secondary cases of HD ascertained through probands having both disorders, indicating a strong familial clustering of the association. This implies that a young adult at risk for HD who has had episodes of severe depression has considerably more than 50 per cent likelihood of progressing to manifest HD. Although auditory hallucinations appear occasionally in patients with HD, most do not meet current criteria for schizophrenia.
