The purpose of this study is to identify a combination of the most informative patterns that allow a differentiated approach to the diagnosis of age-related cognitive impairment. Patients and methods: 213 patients were examined (99 patients 50–65 years old, 114 patients over 65 years of age) of “Federal Centre for High Medical Technologies” of Russian Ministry of Health (Kaliningrad). All patients complained for impaired mental performance, memory and attention. A neuropsychologic testing was conducted using next scales: Montreal Cognitive Assessment (MoCA), Hospital Anxiety and Depression Scale (HADS), Multidimensional Fatigue Inventory (MFI-20) and additional cognitive impairment tests. For statistical analysis, machine learning algorithms, Python programming language, and Pandas and SciPy libraries were used. Results: for patients in the 50–65 age category, high relevance was found for executive dysfunction, decreased attention span, fatigue, anxiety, and endocrine system disorders. For patients over 65 years of age, significant features were semantic aphasia, perceptual and memory impairment, hyperlipidemia, history of ischemic stroke, and obesity. A significant negative correlation for the age index was found with the parameters of depression and anxiety; a positive correlation was found with the index of physical asthenia, disorders of perception, memory and semantic processing of information. Conclusion: the results demonstrate prevalence of cognitive dysfunctions in elderly patients. The tests assessing visual perception and semantic information processing can be of interest in early degenerative cognitive impairments diagnosis in elderly age. Discriminant analysis of a wide range of age-related variables will allow to make more effective aging trajectories prediction without any time-consuming diagnostic methods.","PeriodicalId":516298,"journal":{"name":"Psikhiatriya","volume":"63 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141806641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to study the influence of family traditions and social environment on alcohol consumption by patients with mental disorders. Patients: 106 patients with various mental disorders who received treatment in inpatient and outpatient settings. Methods: patient information was received from the medical record and interviews using questionnaire “Alcohol use: experience, pattern, treatment” and scales: Alcohol Use Disorders Identification Test (AUDIT), Udvalg for Kliniske Undersogelser Scale (UKU), Drug Attitude Inventory-10 (DAI-10). Results: the proportion of patients with high risk for alcohol use problems was 21% of all patients. Patients with a high level of risk differed in the style of drinking alcohol in the parental family: their parents drank alcohol more often. These patients also had their first experience of drinking alcohol in their parental family. There were more people who drank alcohol in large quantities in the past environment of such patients. Although high-risk patients had changed their current environment, they were still more likely to make situational alcohol choices, use it more often to cope with difficulties, and appeared to use previously established drinking styles. All high- risk patients began drinking alcohol before the onset of the disease. Conclusions: patients with a high risk of problems with alcohol use are more likely to have learned their drinking style from their parents, and they are more likely to drink alcohol under the influence of the situation. However, one third of patients were able to reduce their alcohol consumption during illness.","PeriodicalId":516298,"journal":{"name":"Psikhiatriya","volume":"21 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141806177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods: using keywords: “cognitive impairments in schizophrenia”, “cognitive impairments in organic personality disorders”, “cognitive impairments in personality disorders”, “MRI in schizophrenia”, “MRI in organic personality disorder”, “MRI in personality disorder”, “forensic neuropsychology”, “schizophrenia and criminal actions”, “organic personality disorders and criminal actions”, “personality disorders and criminal actions” the search and analysis of scientific publications was carried out in PubMed, Scopus, and RSCI databases over the past 5 years. Conclusion: schizophrenia shows deviations in the functioning of frontal and temporal lobes characterized by cognitive impairments: executive functions, attention, auditory-verbal memory, psychomotor slowness, inconsistent behavior, and deficits in volitional efforts. Borderline personality disorder is associated with reduced volume of the anterior cingulate gyrus, hippocampus, amygdala, and prefrontal cortex, dysfunctional interaction between limbic and prefrontal areas resulting in difficulties in emotion identification and impulsivity. Individuals with a history of traumatic brain injury (TBI) and secondary personality disorders exhibit diffuse gray matter damage affecting frontal, temporal, and parietal regions, emphasizing dysfunction of limbic-reticular complex structures with cognitive impairments including decreased thinking speed, attention stability, executive functions, auditory-verbal memory, visual-spatial memory, visual-motor coordination, and decreased impulse control. Individuals with mental disorders who commit criminal acts often exhibit deficiencies in frontal lobes and associated disturbances in executive components of mental activity, particularly cognitive flexibility and planning. Neuropsychological methods for studying cognitive functions can be used to obtain additional information in forensic psychiatric examinations.","PeriodicalId":516298,"journal":{"name":"Psikhiatriya","volume":"47 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of study: the analysis of the significant concepts of the evolutionary approach to understanding the origins and typology of antisocial, or dissocial, personality disorder. Material and methods: a narrative review of contemporary English-language psychiatric and psychological literature using all available search engines using the keywords “antisocial psychopathy” and “evolutionary psychiatry and psychology”. Discussion and conclusion: in English-language psychiatric and psychological literature the affective component of antisocial traits, emphasized only in ICD-10, is called “primary psychopathy,” while the behavioral component of antisocial traits, associated with “sensation seeking” and “hyperactivation,” is called “secondary” psychopathy. Evolutionary and ecological approaches emphasize the adaptive role of aggressive and antisocial behavior, viewing such behavior as a “high-risk strategy” in social and sexual competition, as “costly” but potentially adaptive (rather than as “behavioral dysfunctions”). The understanding of persistent antisocial behavior as a social “trickster” strategy exploiting the trust and cooperative behavior of others is based on the R. Axelrod-W. Hamilton “iterated” prisoner’s dilemma. In the Prisoner’s Dilemma evolutionary model, the player’s payoff is determined by the effects on “fitness”: survival and fertility. Participating in several interactions with individuals, an antisocial “deceiver” with high mobility is able to exist, manifesting itself with a fairly low frequency in the population. Non-cooperative behavior in both animals and humans reduces the fitness of others and includes aggressive behavior, deception, betrayal, predation and social parasitism. From the point of view of the concept of “economic games,” people with subclinically expressed primary psychopathic traits (emotional coldness, manipulativeness, Machiavellianism) are represented as “strategists” with cooperation partners: they give with reciprocity to those partners whom they consider “highly valuable” (with the potential for great benefits in future), and only “take”, manipulating and deceiving, from those of “low value”. In a broad sense, evolutionary psychologists and psychiatrists find in the characteristics of antisocial individuals a predominance of a set of properties of “fast” life strategies, while the concept of “fast strategies” is also used to explain geographical differences in the prevalence of aggressive behavior.","PeriodicalId":516298,"journal":{"name":"Psikhiatriya","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodologically, the atricle is a narrative literature review. Thirty-three sources were selected for analysis. Discussion and conclusion: according to the data available to present date qualitive and quantitative assessment of resting EEGs cannot be used for the instrumental diagnosis of schizophrenia because the most commonly detected increase in the proportion of slow-wave activity is seen in a several disorders. However, some quantitative spectral estimates of resting state EEG could be used to identify poor prognosis response to antipsychotic therapy, as well as for objective assessment of the dynamics of the mental state. Estimation of the power of slow resting EEG rhythms and other methods of assessing the connectivity of different neural networks could be considered as potential markers of the presence of a specific endophenotype. Modern digital technologies, including machine learning and artificial intelligence algorithms, make it possible to identify resting EEG of the schizophrenic patients from healthy controls with accuracy, sensitivity and specificity more than 95%.

Patients and methods: the study included 50 patients (9 boys, 41 girls), aged 7 to 16 years. Inclusion criteria: 1) schizotypal disorder; 2) eating disorders; 3) mood disorders. Research methods: clinical-psychopathological, psychometric (HDRS, PANSS), follow-up, somatic observation. Results: in patients with schizotypal and mood disorders, the following variants of eating disorder were observed: anorexia nervosa (AN — first type), anorexia nervosa with dominance of bulimia (ANB — second type), anorexia nervosa with dominance of bulimia and vomitomania (ANB + B — third type). Mood disorders in the first type of eating disorder were characterized by a pronounced depressive triad, suicidal thoughts and stupor at the cachectic stage of the disease. Mood disorders in the second type of eating disorder were characterized by a mixed affective state: short unproductive mania, ideas of dysmorphophobia, ideas of attitude, followed by a prolonged depressive state with senesto-hypochondriacal disorders, asthenia, and an increase in cognitive impairment. Mood disorders in the third type of eating disorder were characterized by the presence, of pronounced delusional and dysmorphophobic disorders and ideas of attitude, psychopathic behavior, depersonalization-derealization disorders, asthenia and cognitive impairment. Affective pathology in schizotypal disorder with eating disorder, as well as body dysmorphic syndrome, persisted for a long time. The most severe course was observed in the third group of patients (NANB + B), which was due to a significant proportion of psychotic disorders in the structure of the syndrome and somatic complications due to vomiting behavior.

It is known that the prevalence of certain diseases in males and females is different, in particular, there is a multiple increase in the incidence of dementia in females compared to males in Alzheimer’s disease (AD). Taking into account the role of neuroinflammation in the pathogenesis of neurodegenerative diseases, there is reason to assume gender differences in inflammation indicators at different stages of dementia in AD. The aim of the study was to conduct comparative analysis of indicators of the inflammatory system in the blood plasma of males and females at different stages of Alzheimer’s disease. Patients, control group and methods: a total of 210 patients with AD (101 males and 109 females) aged 49 to 94 years (average age 72.3 ± 8.2) with varying degrees of dementia severity, i.e. mild, moderate, severe, were examined. In peripheral blood plasma, the enzymatic activity of leukocyte elastase (LE) and the functional activity of α1-proteinase inhibitor (α1-PI) were determined by the spectrophotometric method, and the level of C-reactive protein (CRP) and IL-6 were determined by the enzyme-linked immunosorbent method (ELISA). The control group consisted of 52 healthy people, who did not differ from the patients in age and gender. Results and discussion: in the blood of patients with varying severity of dementia in AD, a statistically significant increase in α1-PI activity was observed compared to controls (p < 0.0001), regardless of gender. For all subgroups of patients with AD, the indicators of LE enzymatic activity were within the control range or beyond its lower limit. Low LE activity was observed in males compared to females both in the general group and in moderate dementia (p = 0.005105, p = 0.028672, respectively). In severe dementia, a significant decrease in LE activity compared to the controls did not depend on gender. Low LE activity in the blood of patients with AD, along with elevated levels of other inflammatory markers, may reflect a critical violation of the permeability of the blood-brain barrier and/or functional exhaustion of neutrophils due to a long-term inflammatory process. In males, compared with females, an increase in the level of the pro-inflammatory cytokine IL-6 was detected in the general group and in moderate dementia (p = 0.021238, p = 0.027894, respectively). A highly significant increase in CRP levels was only detected in males in subgroups with different severity of dementia. CRP levels in males were significantly higher than in females at the stage of moderate and severe dementia (p = 0.000906, p = 0.000049, respectively).

Modern neuroimaging techniques contribute to the understanding of the pathophysiological mechanisms of this disorder. The aim was to conduct a systematic review of the scientific literature to confirm that catatonia is associated with structural and functional changes in the brain. The analysis made up researches using diffusion MRI for judgement on indirect measure of changes in white or gray matter density using a fractional anisotropy (FA) and resting state functional MRI for assessment a measure of connectivity. Materials and methods: PubMed, ScienceDirect and Mendeley databases were searched using the search terms (and their derivatives) for: “catatonia”, “resting state functional magnetic resonance imaging” and “catatonia”, “diffusion weighted magnetic resonance imaging”. The search yielded 147 publications for preliminary screening, of which 96 were on fMRI of catatonia and 51 on dMRI. During the screening stage, duplicates and articles that could not be accessed were removed. This left 21 fMRI articles and 18 dMRI articles.
