Affective disorders accompanied by cognitive disorders in inpatients with cardiovascular diseases: a clinical and pathopsychological study
Bibliographic record
Abstract
BACKGROUND: The multimorbidity of affective, cognitive, and cardiovascular diseases is an urgent issue of the contemporary medicine due to their severity, resistance to therapy, social maladjustment, and low quality of life. Common pathogenetic mechanisms, including endothelial dysfunction and disorders of the frontal and subcortical connections, enhance these conditions, increasing the risks of dementia and mortality. AIM: To study the clinical and psychopathological structure of affective disorders and comorbid cognitive disorders in inpatients with cardiovascular diseases in various age groups. METHODS: An observational, single-center study was conducted from January 2023 to June 2024 at the University Clinic of the Russian University of Medicine. The study involved 121 patients with cardiovascular diseases and non-psychotic mental disorders, including 47 (38.8%) with comorbid affective and cognitive disorders. The patients were divided into three age groups, 45–59, 60–74, and 75–90 years. Clinical psychopathological and psychometric (Hospital Anxiety and Depression Scale, Montreal Cognitive Assessment) and neuropsychological methods (clock drawing test, Luria’s method) were used. Statistical analysis was performed using Fisher’s exact test and Student’s t-test. RESULTS: In 85.1% of patients, we detected organic emotional disorders, mainly with alarming symptoms. Significant differences in the clinical structure of affective disorders between the groups indicate age-related differences (p = 0.045). Cognitive disorders (visual and constructional praxis, attention, memory, abstract thinking) are associated with vascular changes and dysfunction of the frontal lobes. The Montreal Cognitive Assessment scores were in the range of 18–27; the average score in the 45–59 group (24.9 ± 0.3) was higher compared to the 60–74 (23.5 ± 0.2; p 0.05) and 75–90 groups (23.4 ± 0.3; p 0.05). Moderate cognitive disorders were detected in 55.3% of cases, severe cognitive disorders were detected in 19.2% of cases, and 25.5% of cases were within the normal range. Subjective cognitive complaints related to the risk of dementia were not confirmed by tests in 27.6% of cases. Attention and abstract thinking disorders increased with age (p 0.05); whereas speech disorders showed no significant differences (p 0.05). CONCLUSION: The study highlights the importance of early diagnosis and an interdisciplinary approach to multimorbid conditions and a qualitative analysis of the psychopathological and pathopsychological structure of affective and cognitive disorders in cardiovascular cases. The limitation is the small sample size, requiring further research on a larger sample of patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
