The aim of this study was to evaluate anosognosia in acute stroke phase in order to type of stroke (ischemia, hemorrhage) and stroke localization as well as post-stroke patients recovery. Subjects and methods: In this prospective analysis were included 191 patients (96 males and 95 females) with first-ever stroke who were treated at the Department of neurology of the University Clinical Center in Tuzla. All patients were tested to anosognosia presence in acute stroke phase according to the modified Bisiach scale (7), while the level of disability was assessed using the Rankin scale (8) and level of functioning in daily activities using the Barthel index (9). Re-testing was done in week five post-stroke. Results: The average age of patients was 66.41 (mean age 10.21). Ischemic stroke had 168 patients (88%) while 23 (12%) the hemorrhagic one. The lesions localized to the right hemisphere were in 111 (58.11%) patients as well as in 80 (41.89%) patients with lesions localized to the left hemisphere. Anosognosia with no statistical significance was verified in 28% of patients in acute stroke phase, more often caused by lesions to the right hemisphere. Otherwise, significantly more frequent anosognosia was present in patients with hemorrhagic stroke mostly caused by massive lesions localized to the right hemisphere. Conclusion: Presence of anosognosia in patients with stroke vitally influenced patient’s functional status in re-testing phase just as well as in the acute stroke phase.

Introduction: The depression is a common mental disorder, especially after a stroke, which further aggravates the recovery. Aim: To analyze depression within 48 hours and fifteen days after ischemic stroke in relation to gender and location (brain hemisphere and brain circulation). Methods: We analyzed 40 patients (65.3±10.3 years), half of them were women. Mean age of women was 66.35±7.31 years and men 64.2±12.68 years (p= 0.5). Ischemic stroke was verified by computed tomography. Levels of depression were measured with self-estimated Zung’s scale. On the tests, score of 50 and higher verified depression. Criteria made by Domasio were used to determine location of the IS. Results: Mean value on depression scale in acute phase of ischemic stroke was 46.85 ± 8.6 and in subacute phase 43.4 ± 8 (p =0.06). In 19 (47.5%) patients (55% of women, 40% of men; p=0.3) depression was found during the first and in 10 (25%) patients (35% of women, 15 % of men; p=0.06) during the second evaluation (p<0.019). Mean value on depression in acute phase of illness in women was 49.1 ± 7.38, as well as in men 44.6 ± 9.22 (p=0.088) and in subacute phase in women 45.25 ± 8.04, as well as in men 41.5 ± 7.75 (p=0.16). Concerning location of ischemic stroke, there were no significant differences in levels of depression. Conclusion: Number of patients with post-stroke depression is significantly lower in subacute phase of ischemic stroke. Although the number of depressive women and their depression scores are higher, gender differences are not statistically significant. There is no correlation between post-stroke depression and location of lesion in acute and subacute phase of illness.

Introduction: Small number of studies have evaluated the mortality and the degree of functional disability of post-stroke delirium, and our aim was to determine that. Patients and Methods: Comprehensive neuropsychological assessments were performed within the first week of stroke onset, at hospital discharge, and followed-up for 3, 6 and 12 months after stroke. We used diagnostic tools such as Glasgow Coma Scale, Delirium Rating Scale, National Institutes of Health Stroke Scale and Mini-Mental State. Results: Delirious patients had a significantly higher mortality (p = 0.0005). As opposed to the type of stroke mortality was higher after ischemic (p = 0.0005). The patients without delirium had significantly better cumulative survival during the first year after stroke (p = 0.0005). Delirious patients aged ≥65 years had a significantly lower cumulative survival during the first year after stroke (p = 0.0005). In relation to the type of stroke delirious patients with ischemic had a significantly lower cumulative survival during the first year after stroke (p = 0.0005). Delirious patients had a greater degree of functional impairment at discharge (p = 0.01), three (p = 0.01), six months (p = 0.01) and one year (p = 0.01) after stroke. Conclusion: Delirious patients have a significantly higher mortality, lower cumulative survival and a greater degree of functional disability in the first year after stroke.

Introduction: Transcranial sonography (TCS) is a relatively new ultrasound modality which could display echogenicity of human brain tissue through the intact skull. TCS may be useful in differentiation of idiopathic Parkinson’s disease (PD) from other parkinsonian disorders. Therefore, we studied different ultrasound markers by TCS in individuals with Parkinson’s disease. Patients and Methods: We performed TCS in 44 patients with PD and 22 patients with other parkinsonian disorders. Echogenic sizes of the substantia nigra (SN) and the lentiform nuclei (LN), as well as the width of the third ventricle and the frontal horns of the lateral ventricle, were measured. We also analyzed the echogenicity of the brainstem raphe (BR). Results: An unilateral hyperechogenic SN was observed in 31 (70%) patients with PD and only in 2 patients (9%) with other parkinsonian disorders (P<0.0001). Hyperechogenicity of the LN was no observed in patients with PD; however, it was present in 7 (32%) patients with other parkinsonian disorders (P=0.0002). Diameter of third ventricle (8.6+/-2.2 mm vs. 6.9+/-1.7mm, P=0.001), right (18.5+/-2.6 mm vs. 16.5+/-2.3 mm, P=0.003) and left frontal horn of lateral ventricle (19.0+/-3.7 mm vs. 16.2+/-2.6 mm, P=0.0006) was significantly wider in patients with other parkinsonian disorders compared with patients with PD. There was no difference in presence of hypoechogenic or interrupted BR in patients with PD and patients with other parkinsonian disorders (39% vs. 27%, P=0.4). Conclusion: TCS is a promising diagnostic technique and can be very helpful in differentiating between idiopathic Parkinson’s disease and other parkinsonian disorders.

Introduction: Basic cognitive functions such as: alertness, working memory, long term memory and perception, as well as higher levels of cognitive functions like: speech and language, decision-making and executive functions are affected by aging processes. Relations between the receptive vocabulary and cognitive functioning, and the manifestation of differences between populations of elderly people based on the primary disease is in the focus of this study. Aim: To examine receptive vocabulary and cognition of elderly people with: verified stroke, dementia, verified stroke and dementia, and without the manifested brain disease. Material and Methods: The sample consisted of 120 participants older than 65 years, living in an institution. A total of 26 variables was analyzed and classified into three groups: case history/anamnestic, receptive vocabulary assessment, and cognitive assessments. The interview with social workers, nurses and caregivers, as well as medical files were used to determine the anamnestic data. A Montreal Cognitive Assessment Scale (MoCA) was used for the assessment of cognition. In order to estimate the receptive vocabulary, Peabody Picture Vocabulary Test was used. Results: Mean raw score of receptive vocabulary is 161.58 (+–21:58 points). The best results for cognitive assessment subjects achieved on subscales of orientation, naming, serial subtraction, and delayed recall. Discriminative analysis showed the significant difference in the development of receptive vocabulary and cognitive functioning in relation to the primary disease of elderly people. The biggest difference was between subjects without manifested brain disease (centroid = 1.900) and subjects with dementia (centroid = -1754). Conclusion: There is a significant difference between elderly with stroke; dementia; stroke and dementia, and elderly people without manifested disease of the brain in the domain of receptive vocabulary and cognitive functioning. Variables of serial subtraction, standardized test results of receptive vocabulary, delayed recall, abstraction, orientation and vigilance successfully discriminate studied groups.

Background: Fatigue is usually defined as a subjective lack of physical and/or mental energy necessary for doing everyday activities. Fatigue is a subjective condition, and there is not a valid definition of fatigue after a stroke at the moment. Aim: The analysis of frequency of fatigue syndrome in 200 patients after an ischemic stroke and its effect on cognitive functioning and quality of life after an ischemic stroke was conducted. The measuring instruments for the assessment of fatigue used were the Chalder Fatigue Scale, for cognitive functioning the Mini-Mental State Examination, and for the quality of life SF-36, scale for measuring quality of life. Neurological and neuropsychological testings of the participants were conducted three months after an ischemic stroke – first testing, six months after an ischemic stroke – second testing, and twelve months after an ischemic stroke – third testing. Results: Fatigue syndrome was noted in 68% of the patients three months after an ischemic stroke, in 71% in testing after six months, and 70% after twelve months. The mean values of MMSE score in the patients with and without fatigue syndrome was between 28 and 29 in all testings, which indicates that they had normal cognitive functioning. The significance of differences in the MMSE score in the patients with and without fatigue syndrome in the first, second and third testing was tested using HI-squared test and the results showed that there were no statistically significant differences (p>0.005). In comparison of quality of life between the patients with and without fatigue the results showed that the patients without fatigue syndrome had significantly better quality of life in comparison with the patients with fatigue syndrome in the field of mental and physical health (p< 0.0001). Conclusion: Fatigue syndrome after an ischemic stroke has a significant frequency (68-71%) and duration. Fatigue syndrome does not affect cognitive functioning of patients after an ischemic stroke but it leads to impaired quality of life of patients in all areas.

Introduction: Psychological stress and changes in hypothalamic-pituitary-adrenal (HPA) axis in period after diagnosis of “de novo” Parkinson disease (PD) could be a big problem for patients. Materials and Methods: We measured psychological stress and changes in hypothalamic-pituitary-adrenal axis (HPA) in thirty patients (15:15) with “de novo” Parkinson’s disease, average age 64.17 ± 13.19 (28-82) years (Department of Neurology, University Clinical Center Tuzla). We used Impact of events scale (with 15 questions) to evaluate psychological stress. Normal level of morning cortisol was 201-681 nmol/l, and morning adrenocorticotropic hormone (ACTH) up to 50 pg/ml. Results: Almost 55% patients suffered from mild or serious psychological stress according to IES testing (Horowitz et al.). Non-iatrogenic changes in HPA axis were noticed at 30% patients. The differences between female and male patients regarding to the age (p=0.561), value of cortisol (p=0.745), value of ACTH (p=0.886) and IES testing (p=0.318) were not noticed. The value of cortisol was the predictor of value of ACTH (r=0.427). Conclusion: Psychological stress and changes in hypothalamic-pituitary-adrenal axis are present in patients with “de novo” PD. There is significant relation between values of cortisol and ACTH. Psychological stress is frequent problem for “de novo” PD patients.

Background: There have been only a small number of studies that have evaluated the outcome of post-stroke delirium. Objectives: To evaluate the effects of gender, age, stroke localization, delirium severity, previous illnesses, associated medical complications on delirium outcome as well as, to determine effects of delirium on cognitive functioning one year after stroke. Patients and Methods: Comprehensive neuropsychological assessments were performed within the first week of stroke onset, at hospital discharge, and followed-up for 3, 6 and 12 months after stroke. We used diagnostic tools such as Glazgow Coma Scale, Delirium Rating Scale, National Institutes of Health Stroke Scale and Mini-Mental State. Results: Patients who developed post-stroke delirium had significantly more complications (p = 0.0005). Direct logistic regression was performed to assess the impact of several factors on the likelihood that patients will die. The strongest predictor of outcome was age, mean age ≥ 65 years with a odds ratio (OR) 4.9. Cox’s regression survival was conducted to assess the impact of multiple factors on survival. The accompanying medical complications were the strongest predictor of respondents poore outcome with Hazard-risk 3.3. Cognitive assessments including Mini Mental State score have showen that post-stroke delirium patients had significant cognitive impairment, three (p = 0.0005), six months (p = 0.0005) and one year (p = 0.0005) after stroke, compared to patients without delirium. Conclusion: Patient gender, age, localization of stroke, severity of delirium, chronic diseases and emerging complications significantly affect the outcome of post- stroke delirium. Delirium significantly reduced cognitive functioning of after stroke patients.
