    COGNITIVE FUNCTIONS IN MULTIPLE SCLEROSIS PATIENTS DEPENDING ON THE DIFFERENT RISK FACTORS PRESENCE
    (ALUNA, 2021-10) Kopchak Oksana; Odintsova Tetiana; Pulyk Oleksandr
    The aim: To clarify the influence of different risk factors on cognitive impairment (CI) in general and in separate domains and their association with MRI findings in patients with relapsing-remitting (RRMS) and progressive forms of multiple sclerosis (SPMS and PPMS). Materials and methods: One hundred and thirty-seven participants with MS (102 females and 35 males) aged from 22 to 69 years were enrolled into this study. All patients completed the Montreal Cognitive Assessment (MoCA), Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A) and undergone MRI. Results: According to MS phenotypes all participants were divided into two groups: patients with RRMS (n= 106) and with progressive phenotypes (n= 31). A significant positive correlation was present between MoCA and BDI scores in all participants (p= 0,0015). Presence of anxiety did not demonstrate any valid influence on cognitive performance, although severe anxiety was significantly more often found in subjects with progressive phenotypes in presence of brain atrophy (p= 0,0028). Patients with higher education had no CI more frequently compare to those without it (p= 0,0019), whereas, participants smoking cigarettes had higher prevalence of severe CI than non-smokers (p= 0,0061). Conclusions: Among cognitive domains memory, visual-spatial and executive functions, abstract thinking were impaired the most in MS patients, though abstract thinking was more often affected in progressive forms. The results demonstrated that physical disability, depression and smoking negatively impacted cognitive performance, meanwhile presence of higher education demonstrated a favorable influence on cognition in MS patients.

    Predicting cognitive impairment and psycho-emotional disorders in Multiple Sclerosis patients according to MRI findings
    (AMPH, 2022-12-30) Odintsova Tetiana; Kopchak Oksana
    Objectives. The aim of our study was to assess the probability of cognitive impairment (CI) in general and in separate domains, depression, anxiety and sleep disorders onset depending on their association with MRI findings in patients with multiple sclerosis (MS). Materials and methods. 137 patients with MS were enrolled into the study. All participants were divided into two groups: group A included study subjects with relapsing remitting multiple sclerosis (RRMS) and B consisted of patients with secondary progressive multiple sclerosis (SPMS). Results. Participants with progressive forms of MS had a higher risk of CI development compare to the patients with RRMS (p=0,0361). Memory decline onset depended on the presence of the brain atrophy in combination with lesions of the parietal lobe (OR=2.74 (0.85-8.77), p <0.0001) in RRMS cases, furthermore, on presence of combined demyelination in temporal lobe with corpus callosum (OR=17.33 (2.92-103.02), p=0.0006) and parietal lobe separately (OR=7.5 (1.14-49.26), p=0.0239) in patients with SPMS. Conclusions. CI and psycho-emotional disorders can be predicted by means of MRI findings and potentially prevented.

    Prevalence of sexual disorders in relapsing-remitting multiple sclerosis patients depending on various risk factors
    (AMPH, 2024) ODINTSOVA Tetiana; KOPCHAK Oksana
    Objective. Multiple sclerosis is a perilous, disabling, physically as well as mentally, demyelinating disease of the central nervous system. This work aims to evaluate prevalence of sexual dysfunctions and their correspondence with non- and disease related risk factors, as well as with MRI findings in patients with relapsing-remitting multiple sclerosis. Results. Based on conducted multifactorial analysis, the most prominent risk factor associated with presence of sexual dysfunctions in in patients with relapsing-remitting multiple sclerosis was depression. Sexual dysfunctions are tied to cognitive deficit, in general and in separate domains, particularly in memory, executive functions and language. Considering disease-related agents, sensory and motor deficits are linked to the development of sexual dysfunctions in case of relapsing-remitting multiple sclerosis. Among nondisease-related factors, unemployment, marital status, level of education and tobacco smoking are affecting sexual dysfunctions’ severity. According to the MRI, frontal lobe and corpus callosum and periventricular area were affected more often comparing to other brain regions in case of sexual dysfunctions. Conclusions. Patients suffering from relapsing-remitting multiple sclerosis encounter secondary and tertiary sexual dysfunctions. Knowing all struggles of MS, patients should be offered more nuanced management options that will improve their quality of life on a deeper level.

    SLEEP DISORDERS IN RELAPSING-REMITTING MULTIPLE SCLEROSIS PATIENTS
    (Aluna Publishing, 2021) Kopchak Oksana; Odintsova Tetiana
    The aim: Our study aimed at evaluating the relationships between sleep disorders (SD), cognitive impairment (CI), anxiety and depression in patients with relapsing-remitting multiple sclerosis (RRMS). Materials and methods: One hundred and five patients with RRMS (80 females and 25 males) aged from 22 to 67 years (mean age: 41,8±10,7; EDSS:3,5±1,6; disease duration (DD): 10,3±8,5 years) were enrolled into the study. All participants completed questionnaires on sleep (the Pittsburgh Sleep Quality Index /PSQI), cognitive functions (The Montreal Cognitive Assessment /MoCA), anxiety (Hamilton Anxiety Rating Scale /HAM-A), depression (Beck Depression Inventory/ BDI). Results: According to PSQI score the patients were divided into two groups: with (n=42) and without SD (n=63). The patients with SD were older (45,36±1,66 vs 39,41±1,27, p=0.005), had higher EDSS score (3,98±0,26 vs 3,14±0,19, p=0,008), BDI (13,79±1,14 vs 8,96±0,86, p=0,0009) and HAM-A (24,52±1,42 vs 16,56±0,99, p<0,0001) scales compared with patients without SD. The frequency of anxiety (p=0,0034) and depression (p=0,038) was significantly higher in RRMS patients with compared to those without SD. No significant difference was found in gender, DD and MoCA score. In patients with SD significant negative correlation between MoCA and BDI score (r = -0,42, p<0,005) was found. In the group of patients without SD significant negative correlation between MoCA and EDSS (r = -0,27, p=0,03), MoCA and BDI (r = -0,26, p=0,043),) MoCA and HAM-A (r = -0,25, p=0,041) score was detected. Conclusions: Insomnia type SD in RRMS patients were associated with older age, higher EDSS score and presence of anxiety and depression.

    VASCULAR RISK FACTORS AND COGNITIVE FUNCTIONS IN THE PATIENTS WITH CEREBROVASCULAR DISEASE
    (Aluna, 2020) Kopchak Oksana; Bachinskaya Natalia; Pulyk Oleksandr
    The aim: To assess the severity of cognitive impairment (CI) in patients with cerebrovascular disease (CVD) depending on the number of vascular risk factors (VRF). Materials and methods: The study consisted of five hundred and eighty patients with CVD (247 females and 333 males) aged from 45 to 89 years (mean age: 64,1±8,9 years). The patients were divided into 6 groups (I, II, III, IV, V, VI) depending on the number of VRF. The examination consisted of a standard clinical evaluation, neurological examination, the application of neuropsychological tests (the MMSE; the PALT/The Paired Associates Learning Test; clock drawing test), laboratory tests, MRI of brain. Results: According to ANOVA, the greater the number of VRF the patients had, the lower was their total MMSE score corresponding to more pronounced cognitive decline (F=2,97, p=0,012). A significant negative correlation between patients’ age and their MMSE score was detected regardless of their VRF count. The patients of the V and VI groups had substantially lower parameters of immediate, delayed memory and clock drawing test score comparing to the patients of the I group. Conclusions: The presence of 4 and more VRF was related to more pronounced CI in the patients with CVD. Decline of different aspects of memory, attention, spatial orientation, abstract thinking, planning, concentration, executive and visuospatial skills in groups of patients with 4,5 and 6 vascular risk factors was established. Age was substantially associated with cognitive decline in all the group of patients
