[The application of RBANS (Repeatable Battery for the Assessment of Neuropsychological Status) in neurocognitive testing of patients suffering from schizophrenia and dementia]

JUHÁSZ Levente Zsolt, KEMÉNY Katalin, LINKA Emese, SÁNTHA Judit, BARTKÓ György

[Introduction - The purpose of our study was to find out whether the Hungarian adaptation of the RBANS (Repeatable Battery for the Assessment of Neuropsychological Status), a brief neurocognitive screening test, is appropriate for the differentation of healthy and non-healthy subject groups, or for the detection of differences between the cognitive performance of patient groups. Patients and method - The test battery was administrated to 38 healthy subjects, 69 schizophrenic patients, and 18 patients suffering from dementia (10 probable Alzheimer-type and eight vascular dementia). Results - There was a significant decrease of performance in all patient groups compared to the healthy group. In the schizophrenic group, the test indicated a deterioration of functioning in all cognitive areas. The patient group with Alzheimer-type dementia performed only slightly better than the schizophrenic group, because the fall of performance was not significant only one of the cognitive areas (in the visuo-spatial tasks) when compared to the healthy group. There was no difference between the performance of patients with vascular dementia and that of healthy subjects in direct memory, verbal and visuo-spatial tasks. The test results indicated an even deterioration of cognitive areas in patients with Alzheimer-type dementia. As for the vascular dementia group, the most vulnerable area proved to be that of attention, while their verbal functions were relatively spared. The deterioration in other cognitive functions shown by schizophrenic subjects was more moderate, but still significant. A comparison of the RBANS scores of the schizophrenic patients in our study and the result of an American study was also carried out. The global indeces showed no difference; only the pattern of the sub-scales was a little different. Conclusion - The Hungarian version of the RBANS seems appropriate for the differentiation of healthy and deteriorated cognitive performance in a Hungarian patient population.]

[Hypothalamic regulation of the food intake]

PALKOVITS Miklós

[The central regulation of the food intake is organized by a long-loop mechanism involving humoral signals and afferent neuronal pathways to the hypothalamus, obligatory processing in hypothalamic neuronal circuits, and descending commands through vagal and spinal neurons to the body. Receptors sensitive to glucose metabolism, body fat reserves, distension of the stomach, as well as neuropeptide and cannabinoid receptors have been identified and localized in the hypothalamus. Five groups of cells in the hypothalamus - arcuate, paraventricular, ventromedial and dorsomedial nuclei, and the dorsolateral hypothalamic area - contain neurons with either anorexic actions (α-MSH, CART peptide, corticotropin-releasing hormone, urocortin III, cholecystokinin, glucagon-like peptides) or that stimulate food intake (neuropeptide Y, agouti-related peptide, orexins, melanin concentrating hormone, galanin). Intrahypothalamic neuronal circuits exist between these peptidergic neurons including the arcuate-paraventricular and arcuate-dorsolateral hypothalamic projections. Circulating substances carrying signals connected to changes in body food homeostasis and energy balance (leptin, ghrelin, insulin, glucose) enter the hypothalamus mainly through the arcuate nucleus. Neurons in the medulla oblongata that express leptin and insulin receptors, as well as neuropeptide mediators project to the hypothalamus. Vica versa, hypothalamic neurons give rise to projections to autonomic centers in the brainstem and the spinal cord with potential for stimulation or inhibition of food intake, energy balance and ingestion behavior.]

Neurocognitive functions in patients with hepatitis C infection

HORVÁTH Gergely, KELETI Teodóra, MAKARA Mihály, UNGVARI S Gabor, GAZDAG Gábor

Background - With improving treatment options, more attention is being paid to the neurocognitive symptoms related to hepatitis C infection (HCI). While HCI-related neurocognitive impairments are frequently subclinical, they can influence patients’ quality of life and fitness to work. Objective - The aim of this study was to assess HCI patients’ neurocognitive functions and explore the correlations between disease variables and neurocognitive symptoms. Method - The study was conducted between January 1, 2013 and December 31, 2015. All patients with HCI were included in the study who were registered at the Hepatology Outpatient Clinic of Szent István and Szent László Hospitals, met inclusion criteria and volunteered to participate. Patients’ sociodemographic data and medical history were recorded in a questionnaire designed for the study. The 21-item Beck Depression Inventory was used to detect depressive symptoms. Six computerized tests were used to evaluate patients’ neuropsychological functions. Results - Sixty patients participated in the study. In comparison with general population standards, patients demonstrated poorer performance in several neurocognitive tests. Neuropsychological performance was correlated with age, sex, length of time since HCI diagnosis, Fibroscan score and the number of previous antiviral treatments. Conclusions - The study’s main finding is that compared to general population standards, patients with hepatitis C virus-related disease exhibit impaired neuropsychological functioning in visuomotor and visuospatial functions, working memory, executive functions, and reaction time. Executive functions and reaction time were the most sensitive indicators for the length and severity of disease. Deterioration in these functions has a major negative effect on work performance particularly in certain occupations.
