Abstract

The article presents a study devoted to the study of cognitive dysfunctions in patients with schizophrenia and endogenous depression in their relationship with the functioning of the magnocellular and parvocellular systems. Mismatch in the work of neural systems leads to violations of the integrity of visual perception and to a violation of the selectivity of thinking in endogenous patients, which makes it difficult to assess and select meaningful, essential information in the formation of judgments. 60 patients with schizophrenia (43 (75%) male and 17 (25%) female; mean age ― 34.0±12.0 years) and 25 patients with endogenous depression (11 (44%) male and 14 (56%) female, mean age ― 38.0±13.6 years) with the use of psychophysiological (the method of visocontrastometry with an assessment of the contrast sensitivity of the visual system, the method of assessing the noise immunity of the visual system) and experimental psychological methods (Trial-Making test by Reitan, Memorizing 10 words, Poppelreiter's figures, Incomplete images, Excluding the 4th superfluous). The established features of cognitive dysfunctions in endogenous depression and schizophrenia are associated with the features of the functional state of the magnocellular and parvocellular neuronal systems and the nature of the interaction of these systems. The specificity of impairments in cognitive functions in patients with endogenous depression is due to changes in the dynamic component of cognitive activity, while the specificity of impairments in cognitive functions in patients with schizophrenia is associated with changes in the selectivity of information and early sensory defects. The data obtained make it possible to develop an idea of the profiles of sensory-cognitive impairments in endogenous depression and schizophrenia, which is of particular importance for differential diagnosis.

精神分裂症和内源性抑郁症患者认知功能与大细胞和副细胞系统相互作用的特征。

本文介绍了一项研究，致力于研究精神分裂症患者的认知功能障碍和内源性抑郁症与大细胞和旁细胞系统功能的关系。神经系统工作的不匹配导致了内源性患者视觉感知完整性的破坏和思维选择性的破坏，使得判断形成过程中难以评估和选择有意义的、必要的信息。精神分裂症60例，其中男性43例(75%)，女性17例(25%);采用心理生理学(视觉对比测量法与视觉系统对比敏感度评估法、视觉系统抗噪性评估法)和实验心理学方法(Reitan试测法、记忆10个单词法、Poppelreiter图法、不完整图像法、记忆法)对25例内源性抑郁症患者(男性11例(44%)、女性14例(56%)，平均年龄- 38.0±13.6岁)进行研究。不包括第4个多余的)。内源性抑郁症和精神分裂症中认知功能障碍的已知特征与大细胞和旁细胞神经元系统的功能状态特征以及这些系统相互作用的性质有关。内源性抑郁症患者认知功能障碍的特异性与认知活动动态成分的改变有关，而精神分裂症患者认知功能障碍的特异性与信息选择性的改变和早期感觉缺陷有关。所获得的数据使内源性抑郁症和精神分裂症的感觉认知障碍概况有可能发展，这对鉴别诊断特别重要。
