Abstract
Introduction Myotonic dystrophy type 1 (DM1) and 2 (DM2) are genetically determined progressive muscular disorders with multisystemic affection, including brain involvement. Transcranial sonography (TCS) is a reliable diagnostic tool for the investigation of deep brain structures. We sought to evaluate TCS findings in genetically confirmed DM1 and DM2 patients, and further correlate these results with patients' clinical features. Methods This cross-sectional study included 163 patients (102 DM1, 61 DM2). Echogenicity of the brainstem raphe (BR) and substantia nigra (SN) as well as the diameter of the third ventricle (DTV) were assessed by TCS. Patients were evaluated using the Hamilton Depression Rating Scale, Fatigue Severity Scale and Daytime Sleepiness Scale. Results SN hyperechogenicity was observed in 40% of DM1 and 34% of DM2 patients. SN hypoechogenicity was detected in 17% of DM1 and 7% of DM2 patients. BR hypoechogenicity was found in 36% of DM1 and 47% of DM2 subjects. Enlarged DTV was noted in 19% of DM1 and 15% of DM2 patients. Older, weaker, depressive, and fatigued DM1 patients were more likely to have BR hypoechogenicity (p < 0.05). DTV correlated with age and disease duration in DM1 (p < 0.01). In DM2 patients SN hyperechogenicity correlated with fatigue. Excessive daytime sleepiness was associated with hypoechogenic BR (p < 0.05) and enlarged DVT (p < 0.01) in DM2 patients. Conclusions TCS is an easy applicable and sensitive neuroimaging technique that could offer new information regarding several brainstem structures in DM1 and DM2. This may lead to better understanding of the pathogenesis of the brain involvement in DM with possible clinical implications.

Abstract
The function of cerebral small vessels can be assessed using cerebral vasomotor reactivity (VMR). Our aim in this retrospective cross-sectional study was to investigate a correlation between carotid artery stenosis measured through ultrasonographic morphological and hemodynamic parameters and cerebral VMR. A total of 285 patients (125 males; mean age 54) were included. The breath-holding index (BHI) was used to evaluate cerebral VMR. Ultrasonographic carotid artery parameters were collected: the presence and characteristics of carotid plaques, the degree of carotid diameter stenosis, intima-media thickness (IMT), peak systolic velocity (PSV), and end diastolic velocity (EDV). Additionally, hemodynamic parameters of the middle cerebral artery (MCA) were evaluated, including the mean flow velocity (MFV) and pulsatility index (PI). The following was collected from patients' medical histories: age, gender, and vascular risk factors. A negative correlation between the BHI and age (r = -0.242, p < 0.01), BHI and the presence of carotid plaques, BHI and IMT (r = -0.203, p < 0.01), and BHI and the PI of MCA on both sides (r = -0.268, p < 0.01) was found. We found a positive correlation between the BHI in the left MCA and EDV in the left internal carotid artery (r = 0.121, p < 0.05). This study shows the correlation between cerebral VMR and carotid stenosis but indicates a higher influence of morphological parameters on VMR values.

Abstract
Headache disorders are a significant global health burden, leading to reduced quality of life. While vast pharmacological treatments are available, they may be associated with adverse effects or inadequate efficacy for some patients, therefore there is a need for exploring alternate treatment strategies. This review gives a brief explanation and evaluation of some established and emerging non-pharmacological approaches for headache management, focusing on nutraceuticals and diet, acupuncture, cognitive behavioral therapy (CBT), biofeedback, relaxation techniques, autogenic training, and neuromodulation. Special consideration is given to psychological interventions as they increase patient self-efficacy and provide strategies for managing chronic pain. Future research should focus on optimizing these therapies, identifying patient-specific factors influencing their effectiveness, and integrating them into holistic headache management strategies.

Abstract
Cerebral amyloid angiopathy-related inflammation (CAA-rI) is a largely reversible, subacute encephalopathy, which is considered as a rare variant of cerebral amyloid angiopathy (CAA). Although the diagnosis of this inflammatory vasculopathy is generally clinico-pathologic, a probable or possible diagnosis can often be established based on current clinico-radiological diagnostic criteria. This is important since CAA-rI is considered as a treatable disorder, which most commonly occurs in the elderly population. Behavioral changes and cognitive deterioration are highlighted as the most common clinical signs of CAA-rI, followed by a heterogeneous spectrum of typical and atypical clinical presentations. However, despite the well-established clinical and radiological features incorporated in the current diagnostic criteria for this CAA variant, this rare disorder is still insufficiently recognized and treated. Here, we have shown three patients diagnosed with probable CAA-rI, with significant heterogeneity in the clinical and neuroradiological presentations, followed by different disease courses and outcomes after the introduction of immunosuppressive treatment. Moreover, we have also summarized up-to-date literature data about this rare, yet underdiagnosed, immune-mediated vasculopathy.

Abstract
Background Sex is a significant determinant of survival and functional outcome after stroke. Long-term cognitive outcome after acute lacunar stroke in the context of sex differences has been rarely reported. Methods A cohort of small vessel disease (SVD) patients presenting with first-ever acute lacunar stroke and normal cognitive status has been evaluated 4 years after the qualifying event for the presence of cognitive impairment (CI) with a comprehensive neuropsychological battery. Differences in baseline clinical and neuroimaging characteristics were compared between sexes in relation to cognitive status. Results A total of 124 female and 150 male patients were analyzed. No difference was detected between the groups regarding age (p = 0.932) or frequency of common vascular risk factors (p > 0.1 for all). At the baseline assessment, women had more disabilities compared to men with a mean modified Rankin scale (mRS) score of 2.5 (1.5 in men, p < 0.0001). Scores of white matter hyperintensities (WMH) of presumed vascular origin and a total number of lacunes of presumed vascular origin on brain MRI were higher in women compared to men (p < 0.0001 for all). As many as 64.6% of patients had CI of any severity on follow-up, women more frequently (77.4%) than men (54.0%; p < 0.0001). Univariate logistic regression analysis showed that female sex, higher NIHSS and mRS scores, presence of depression, and increasing WMH severity were associated with an increased risk for CI. Multivariate regression analysis indicated that only depression (OR 1.74, 95%CI 1.25-2.44; p = 0.001) and WMH severity (OR 1.10, 95%CI 1.03-1.17; p = 0.004) were independently associated with the CI. Conclusion At the long-term follow-up, women lacunar stroke survivors, compared to men, more frequently had CI in the presence of more severe vascular brain lesions, but this association was dependent on the occurrence of depression and severity of WMH, and could not be explained by differences in common vascular risk factors.

Abstract
PURPOSE The aim of the present study was to assess the burden and health care use of adult patients with migraine and tension type headache in a post-conflict area of Serbia. METHODS This cross-sectional study was conducted on a representative sample of adults, living in predominantly Serb communities on the Kosovo and Metohija territory. The required data was obtained through a survey, utilizing a culturally-adapted questionnaire. The study sample comprised of 1,062 adults. RESULTS In the year preceding the study, 49.7% of included subjects suffering from migraines and 27.5% of those experiencing tension type headache sought medical assistance for their condition. The majority (88.5%) of the respondents utilized non steroid antiinfammatory drugs as analgesic, while 14.2% used prophylactic treatment. Migraine sufferers reported losing on average 11.1 days in a 3-month period, while those experiencing tension type headache lost 4.7 days (p < 0.001) due to headaches, preventing them from partaking in professional, family and social activities. On headache-free days, 24.5% of the respondents were anxious or tense in anticipation of a headache onset, while 30% did not feel that the headache had completely resolved. Moreover, 11.5% of the sample reported never or rarely feeling in control of the headache, while 20% of the respondents were of view that their headaches were not taken seriously by their employer and co-workers and rarely discuss them. Adverse effect of headaches on education is more frequently noted by migraine sufferers than those experiencing tension type headache (p = 0.001), and this disparity persists in relation to career (p < 0.001) and family planning (p = 0.001). CONCLUSIONS In Kosovo and Metohija, primary headaches exert a profound influence on the affected individuals and their community, and thus require recognition as one of the priorities of social initiatives aimed at the enhancement of public health.

Abstract
BACKGROUND AND PURPOSE The optimal management of post-stroke cognitive impairment (PSCI) remains controversial. These joint European Stroke Organisation (ESO) and European Academy of Neurology (EAN) guidelines provide evidence-based recommendations to assist clinicians in decision making regarding prevention, diagnosis, treatment and prognosis. METHODS Guidelines were developed according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The working group identified relevant clinical questions, performed systematic reviews, assessed the quality of the available evidence, and made specific recommendations. Expert consensus statements were provided where insufficient evidence was available to provide recommendations. RESULTS There was limited randomized controlled trial (RCT) evidence regarding single or multicomponent interventions to prevent post-stroke cognitive decline. Lifestyle interventions and treating vascular risk factors have many health benefits, but a cognitive effect is not proven. We found no evidence regarding routine cognitive screening following stroke, but recognize the importance of targeted cognitive assessment. We describe the accuracy of various cognitive screening tests, but found no clearly superior approach to testing. There was insufficient evidence to make a recommendation for use of cholinesterase inhibitors, memantine nootropics or cognitive rehabilitation. There was limited evidence on the use of prediction tools for post-stroke cognition. The association between PSCI and acute structural brain imaging features was unclear, although the presence of substantial white matter hyperintensities of presumed vascular origin on brain magnetic resonance imaging may help predict cognitive outcomes. CONCLUSIONS These guidelines highlight fundamental areas where robust evidence is lacking. Further definitive RCTs are needed, and we suggest priority areas for future research.

The optimal management of post-stroke cognitive impairment remains controversial. These joint European Stroke Organisation (ESO) and European Academy of Neurology (EAN) guidelines provide evidence-based recommendations to assist clinicians in decision making around prevention, diagnosis, treatment and prognosis. These guidelines were developed according to ESO standard operating procedure and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The working group identified relevant clinical questions, performed systematic reviews and, where possible, meta-analyses of the literature, assessed the quality of the available evidence and made specific recommendations. Expert consensus statements were provided where insufficient evidence was available to provide recommendations based on the GRADE approach. There was limited randomised controlled trial evidence regarding single or multicomponent interventions to prevent post-stroke cognitive decline. Interventions to improve lifestyle and treat vascular risk factors may have many health benefits but a beneficial effect on cognition is not proven. We found no evidence around routine cognitive screening following stroke but recognise the importance of targeted cognitive assessment. We described the accuracy of various cognitive screening tests but found no clearly superior approach to testing. There was insufficient evidence to make a recommendation for use of cholinesterase inhibitors, memantine nootropics or cognitive rehabilitation. There was limited evidence on the use of prediction tools for post-stroke cognitive syndromes (cognitive impairment, dementia and delirium). The association between post-stroke cognitive impairment and most acute structural brain imaging features was unclear, although the presence of substantial white matter hyperintensities of presumed vascular origin on acute MRI brain may help predict cognitive outcomes. These guidelines have highlighted fundamental areas where robust evidence is lacking. Further, definitive randomised controlled trials are needed, and we suggest priority areas for future research.

BACKGROUND It is assumed that most cases of embolic stroke of undetermined source (ESUS) are of cardioembolic origin. The data about outcome after the treatment with intravenous thrombolysis (IVT) for this type of acute ischemic stroke (AIS) are limited. We aimed to compare clinical characteristics and outcomes after IVT for AIS between patients with ESUS and cardioembolic stroke (CS). METHODS This study was a single center retrospective analysis of stroke patients treated with IVT. The Trial of ORG 10172 in Acute Stroke Treatment criteria were used to establish stroke etiology subtype at 3 months, while ESUS was considered a subset of stroke of undetermined etiology, defined according to 2014 international criteria. Functional outcome was assessed at 3 months and defined as excellent (modified Rankin scale 0-1) and favorable (modified Rankin scale 0-2). RESULTS Total of 394 patients were treated with IVT; 113 had a cardioembolism, 88 had undetermined stroke subtype, of which 62 met the ESUS criteria. Patients with ESUS were on average younger (63.7 years versus 69.7 years, p = 0.001), had a lower National Institutes of Health Stroke Scale (NIHSS) score on admission (12 versus 15, p = 0.002) and lower prevalence of antiplatelets use (27.4% versus 42.5%, p = 0.04) compared with CS patients. Favorable outcome was more likely in ESUS patients, at discharge (48.4% versus 24.0%, p = 0.002) and after 3 months (71.0% versus 37.2%, p < 0.001). Hemorrhagic transformation was less frequent (17.7% versus 33.6%, p = 0.03) in ESUS patients. Independent predictors of 3‑month favorable outcome were ESUS, the absence of leukoaraiosis on computed tomography (CT) and absence of diabetes as a risk factor. CONCLUSION Patients with ESUS had better outcome after IVT than patients with CS, which can be attributed to younger age and milder strokes in these patients.

Abstract
BACKGROUND Hypo/anechogenicity of the brainstem raphe (BR) structures has been suggested as a possible transcranial parenchymal sonography (TCS) marker associated with depression. AIM The aim of this study was to analyze possible association of the abnormal BR echogenicity in patients with major depression when compared to healthy controls, and to evaluate its clinical and genetic correlates. METHODS TCS was performed in 53 patients diagnosed as major depressive disorder (MDD) without psychotic symptoms and in 54 healthy matched controls. RESULTS The TCS detected BR abnormalities were significantly more frequent in MDD patients (35 out of 53; 66%) in comparison to matched controls (5 out of 56; 9%). The prevalence of short allele (s) homozygocity in the length polymorphism of the promoter region of the serotonin transporter gene (5-HTTLPR) was significantly higher in MDD patients relative to those with normal BR echogenicity. A stepwise statistical discriminant analysis revealed statistically significant separation between MDD patients with and without BR abnormalities groups based on the four predictors combined: the Hamilton Anxiety Rating Scale item 5 ("difficulty in concentration, poor memory"), presence of social phobia, s allele homozygocity of the 5-HTTLPR polymorphism, and presence of generalized anxiety disorder. LIMITATIONS Cross-sectional design and heterogenous treatment of depressed patients. CONCLUSIONS Reduced BR echogenicity in at least a subgroup of MDD patients may reflect a particular phenotype, characterized by more prevalent comorbid anxiety disorders, associated with particular genetic polymorphisms and neurotransmitter(s) deficits, most probably altered serotonergic mechanisms.

Abstract
Objective To evaluate long-term predictors of remission in patients with medication-overuse headache (MOH) by prospective cohort study. Background Knowledge regarding long-term predictors of MOH outcome is limited. Methods Two hundred and forty MOH patients recruited from 2000 to 2005 were included in a one-year follow-up study and then subsequently followed until 31 December 2013. The median follow-up was three years (interquartile range, three years). Predictive values of selected variables were assessed by the Cox proportional hazard regression model. Results At the end of follow-up, 102 (42.5%) patients were in remission. The most important predictors of remission were lower number of headache days per month before the one-year follow-up (HR-hazard ratio = 0.936, 95% confidence interval (CI) 0.884-0.990, p = 0.021) and efficient initial drug withdrawal (HR = 0.136, 95% CI 0.042-0.444, p = 0.001). Refractory MOH was observed in seven (2.9%) and MOH relapse in 131 patients (54.6%). Conclusions Outcome at the one-year follow-up is a reliable predictor of MOH long-term remission.

Abstract
The utility of the differences between cluster headache (CH) and paroxysmal hemicrania (PH) is limited by the considerable overlap of their clinical characteristics. We compared 54 patients with CH and eight patients with PH in terms of demographic features, characteristics of headache attacks, associated autonomic features, temporal forms of disorders, and response to verapamil. According to our results, clinical features that distinguished CH and PH patients were: maximal pain localization, ocular in CH patients and extra-ocular in PH group; mean attack duration was longer and mean attack frequency was lower in CH patients in comparison with PH patients. Conjuctival injection was the only autonomic sign seen more frequently in CH patients. There were more CH patients with episodic and more PH patients with unremitting form of the disorder in examined groups. Although statistical analysis pointed out a significant difference between these clinical features, there was no clinical characteristic that exclusively belonged to one of these headache entities. Demographic characteristics (age, gender, social background), the other headache attack features (nocturnal attacks, interattack tenderness), the other autonomic signs, as well as the response to verapamil did not differ significantly between two groups.

Abstract
We present a prospective study of 240 patients with medication overuse headache (MOH) treated with drug withdrawal and prophylactic medications. At 1-year follow-up, 137 (57.1%) patients were without chronic headache and without medication overuse, eight (3.3%) patients did not improve after withdrawal and 95 (39.6%) relapsed developing recurrent overuse. Age at time of MOH diagnosis, regular use of benzodiazepines, frequency and Migraine Disability Assessment (MIDAS) score of chronic headache, age at onset of primary headache, frequency and MIDAS score of primary headache, ergotamine compound overuse and daily drug intake were significantly different between successfully and unsuccessfully treated patients. Multivariate analysis determined the frequency of primary headache disorder, ergotamine overuse and disability of chronic headache estimated by MIDAS as independent predictors of treatment efficacy at 1-year follow-up.

Abstract
OBJECTIVE Even though statin pretreatment is associated with better functional outcomes and lower risk of mortality in acute ischemic stroke, there are limited data evaluating this association in acute ischemic stroke due to large artery atherosclerosis (LAA), which carries the highest risk of early stroke recurrence. METHODS Consecutive patients with acute LAA were prospectively evaluated from 7 tertiary-care stroke centers during a 3-year period. Statin pretreatment, demographics, vascular risk factors, and admission and discharge stroke severity were recorded. The outcome events of interest were neurologic improvement during hospitalization (quantified as the relative decrease in NIH Stroke Scale score at discharge in comparison to hospital admission), favorable functional outcome (FFO) (defined as modified Rankin Scale score of 0-1), recurrent stroke, and death at 1 month. Statistical analyses were performed using univariable and multivariable Cox regression models adjusting for potential confounders. All analyses were repeated following propensity score matching. RESULTS Statin pretreatment was documented in 192 (37.2%) of 516 consecutive patients with LAA (mean age: 65 ± 13 years; 60.8% men; median NIH Stroke Scale score: 9 points, interquartile range: 5-18). Statin pretreatment was associated with greater neurologic improvement during hospitalization and higher rates of 30-day FFO in unmatched and matched (odds ratio for FFO: 2.44; 95% confidence interval [CI]: 1.07-5.53) analyses. It was also related to lower risk of 1-month mortality and stroke recurrence in unmatched and matched analyses (hazard ratio for recurrent stroke: 0.11, 95% CI: 0.02-0.46; hazard ratio for death: 0.24, 95% CI: 0.08-0.75). CONCLUSION Statin pretreatment in patients with acute LAA appears to be associated with better early outcomes regarding neurologic improvement, disability, survival, and stroke recurrence.

Abstract
Background & Purpose:
Statin pretreatment is associated with better functional outcomes and lower risk of mortality in acute ischemic stroke (AIS). We hypothesized that this association may be accentuated in AIS due to large-artery atherosclerosis (LAA) that carries the highest risk of early stroke recurrence.
Methods:
Consecutive patients with acute LAA were prospectively evaluated from seven tertiary-care stroke centers during a three-year period. Statin pretreatment, demographics, vascular risk factors, admission and discharge NIHSS-scores were recorded. The outcome events of interest were neurological improvement during hospitalization (quantified as the relative decrease in NIHSS-score at discharge in comparison to hospital admission), favorable functional outcome (FFO, defined as mRS-score of 0-1), recurrent stroke and death at 1-month. Statistical analyses were performed using univariate and multivariate Cox regression models adjusting for potential confounders. All analyses were repeated following propensity score matching.
Results:
Statin pretreatment was documented in 192 (37.2%) out of 516 consecutive LAA patients (mean age: 65±13 years; 60.8% men; median NIHSS-score: 9 points, interquartile range: 5-18). Neurological improvement during hospitalization was greater in patients with than without statin pretreatment in unmatched and matched analyses (66.7% vs. 34.8%; p<0.001). Statin pretreatement was associated higher rates of 30-day FFO in unmatched and matched (OR for FFO: 0.48; 95%CI: 0.31-0.75) analyses. Statin pretreatment was related to lower risk of 1-month mortality and stroke recurrence in unmatched and matched analyses (HR for recurrent stroke: 0.11; 95%CI: 0.02-0.46, HR for death: 0.24, 95%CI: 0.08-0.75).
Conclusions:
Statin pretreatment in patients with acute LAA appears to be associated with better early outcomes in terms of neurological improvement, disability, survival and stroke recurrence.

Abstract
OBJECTIVE Cerebral small vessel disease (SVD) is associated with late-onset depression and increases the risk for depression after stroke. We aimed to investigate baseline predictors of depression after long-term follow-up in patients with SVD, initially presenting with first-ever lacunar stroke, free of depression and cognitive impairment. METHODS A total of 294 patients with SVD were evaluated 3-5 years after the qualifying event. We analyzed baseline demographic data, vascular risk factors, functional status expressed as a score on modified Rankin Scale (mRS), cognitive status, presence of depression, total number of lacunar infarcts and severity of white matter hyperintensities (WMH) on MRI with Age-Related White Matter Changes scale total score (tARWMC) and Fazekas scale periventricular and deep subcortical scores. RESULTS On follow-up, depression was registered in 117 (39.8%) SVD patients. At the baseline, patients with depression compared with non-depressed were older (64.4 vs 60.9 years; p = 0.007), had higher mRS score (2.8 ± 0.7 vs 1.5 ± 0.7; p < 0.0001) and had more severe lesions on MRI scales (p < 0.0001 for all parameters). On follow-up, depressed patients more frequently exhibited cognitive decline (75.2% depressed vs 56.5% non-depressed; p = 0.003). No difference was detected in risk factor frequency between groups. Multivariate Cox regression analysis adjusted by age and gender revealed independent predictors of depression: baseline mRS >2 (HR 2.17, 95%CI 1.74-2.72; p < 0.0001) and tARWMC (HR 1.05, 95%CI 1.02-1.09; p = 0.005), and cognitive decline on follow-up (HR 1.80, 95%CI 1.12-2.89; p = 0.015). CONCLUSIONS Baseline functional status and severity of WMH and development of cognitive decline predict the occurence of late-onset depression in patients with SVD.

Abstract
The association of proteins and peptides with inorganic material has vast technological potential. An understanding of the adsorption of peptides at liquid/solid interfaces on a molecular-level is fundamental to fully realising this potential. Combining our prior work along with the statistical analysis of 100+ molecular dynamics simulations of adsorption of an experimentally identified graphite binding peptide, GrBP5, at the water/graphite interface has been used here to propose a model for the adsorption of a peptide at a liquid/solid interface. This bottom-up model splits the adsorption process into three reversible phases: biased diffusion, anchoring and lockdown. Statistical analysis highlighted the distinct roles played by regions of the peptide studied here throughout the adsorption process: the hydrophobic domain plays a significant role in the biased diffusion and anchoring phases suggesting that the initial impetus for association between the peptide and the interface may be hydrophobic in origin; aromatic residues dominate the interaction between the peptide and the surface in the adsorbed state and the polar region in the middle of the peptide affords a high conformational flexibility allowing strongly interacting residues to maximise favourable interactions with the surface. Reversible adsorption was observed here, unlike in our prior work focused on a more strongly interacting surface. However, this reversibility is unlikely to be seen once the peptide-surface interaction exceeds 10 kcal mol(-1).

Abstract
Although amyotrophic lateral sclerosis (ALS) is characterized by involvement of motor neurons in the motor cortex, brainstem and spinal cord, there is accumulating evidence that it is a multisystem degenerative disease, with dysfunction of the striatonigral dopaminergic system as well. Transcranial B-mode sonography of the parenchyma enables depiction of the differing tissue echogenicity of midbrain and basal ganglia structures in various movement disorders. Transcranial B-mode sonography was performed in the standard manner in 101 patients with sporadic newly diagnosed ALS and 60 age- and gender-matched controls. Increased frequencies of pathologic substantia nigra hyper-echogenicity (p = 0.027), interrupted brainstem raphe (p = 0.003) and increased third ventricle diameter (p < 0.0001) were detected in ALS patients as compared with healthy controls. Only four ALS patients exhibited some features of parkinsonism. Pathologic findings on transcranial B-mode sonography of parenchyma did not correlate with clinical presentation, functional status or disease subtype. Our study provides additional evidence of multisystem involvement in ALS patients, particularly in subcortical areas.

Abstract
We analyzed (a) insulin sensitivity (IS), (b) plasma insulin (PI), and (c) plasminogen activator inhibitor-1 (PAI-1) in type 2 diabetes (T2D) patients with (group A) and without (group B) atherothrombotic ischemic stroke (ATIS), nondiabetics with ATIS (group C), and healthy controls (group D). IS was determined by minimal model (Si). Si was lower in A versus B (1.18 ± 0.67 versus 2.82 ± 0.61 min-1/mU/L × 104; P < 0.001) and in C versus D (3.18 ± 0.93 versus 6.13 ± 1.69 min-1/mU/L × 104; P < 0.001). PI and PAI-1 were higher in A versus B (PI: 19.61 ± 4.08 versus 14.91 ± 1.66 mU/L; P < 0.001, PAI-1: 7.75 ± 1.04 versus 4.57 ± 0.72 mU/L; P < 0.001) and in C versus D (PI: 15.14 ± 2.20 versus 7.58 ± 2.05 mU/L; P < 0.001, PAI-1: 4.78 ± 0.98 versus 3.49 ± 1.04 mU/L; P < 0.001). Si correlated with PAI-1 in T2D patients and nondiabetics, albeit stronger in T2D. Binary logistic regression identified insulin, PAI-1, and Si as independent predictors for ATIS in T2D patients and nondiabetics. The results imply that insulin resistance and fasting hyperinsulinemia might exert their atherogenic impact through the impaired fibrinolysis.

Abstract
BACKGROUND Involvement of the central nervous system is registered in a relatively small number of patients with sarcoidosis. In this article we present two cases with various neurological symptoms that fulfill criteria for neurosarcoidosis (NS). In addition, we review the literature on NS with special attention to isolated cranial nerve involvement. METHODS AND RESULTS First patient: Neurological examination identified multiple cranial neuropathy, moderate right-sided hemiparesis, polyradiculoneuritis of the lower limbs and positive meningeal signs. Laboratory tests showed serum and cerebrospinal fluid (CSF) inflammatory abnormalities, with increased values of the angiotensin-converting enzyme (ACE). CSF analysis also showed presence of 9 oligoclonal IgG bands. Brain and spine magnetic resonance imaging (MRI) revealed diffuse meningopathy, and focal granulomatous lesion in the body of the L5 vertebra. Lung sarcoidosis was confirmed by additional diagnostic procedures. The patient was treated with Methylprednisolone and a tapering course of oral Prednisone, which reduced the pain in the back and legs and improved the strength of the right leg. However, the other neurological deficiencies remained. After confirming lung sarcoidosis, the patient received Methotrexate in addition to Prednisone but during the following 2 years the patient's condition progressively worsened and ended in death. Second patient: Neurological findings showed weakness of the right n. oculomotorius and the right n. trochlearis, as well as the right-side face weakness. We found raised level of the ACE in serum and CSF. Thorax high-definition computed tomography (HDCTT) showed ribbon-like domains of discrete changes in the pulmonary parenchyma. MRI of the brain showed multiple white matter lesions. This patient also received Methylprednisolone followed by Prednisone, and after two months, ocular motility normalized. CONCLUSION The diagnosis of NS is always a challenge. For this rerason definitive diagnosis requires the exclusion of other causes of neuropathy. Multiple cranial neuropathies should always arouse suspicion of NS.

Abstract
We analyzed (a) insulin sensitivity (IS) and (b) glutathione peroxidase (GSH-Px), glutathione reductase (GR), and superoxide dismutase (SOD) antioxidant enzyme activity in type 2 diabetic (T2D) patients with atherothrombotic infarction (ATI) (group A), lacunar infarction (LI) (B), or without stroke (C) and in nondiabetics with ATI (D), LI (E), or without stroke (F). ATI and LI were confirmed by brain imaging IS levels were determined by minimal model (Si index), and the enzyme activity by spectrophotometry. In T2D patients, Si was lower in A and B versus C (1.14 ± 0.58, 1.00 ± 0.26 versus 3.14 ± 0.62 min(-1)/mU/l × 10(4), P < 0.001) and in nondiabetics in D and E versus F (3.38 ± 0.77, 3.03 ± 0.72 versus 6.03 ± 1.69 min(-1)/mU/l × 10(4), P < 0.001). Also, GSH-Px and GR activities were lower in A and B versus C (GSH-Px: 21.96 ± 3.56, 22.51 ± 1.23 versus 25.12 ± 1.67; GR: 44.37 ± 3.58, 43.50 ± 2.39 versus 48.58 ± 3.67 U/gHb; P < 0.001) and in D and E versus F (GSH-Px: 24.75 ± 3.02, 25.57 ± 1.92 versus 28.56 ± 3.91; GR: 48.27 ± 6.81, 49.17 ± 6.24 versus 53.67 ± 3.96 U/gHb; P < 0.001). Decreases in Si and GR were significantly related to both ATI and LI in T2D. Our results showed that decreased IS and impaired antioxidant enzymes activity influence ischemic stroke subtypes in T2D. The influence of insulin resistance might be exerted on the level of glutathione-dependent antioxidant enzymes.

Abstract
Background and Purpose. White matter changes (WMCs), or leukoaraiosis (LA), are associated with increased age, hypertension, diabetes mellitus, and history of stroke. Although several lines of evidence suggest a role of atherosclerosis in atherothrombotic vascular events, their involvement in LA remains to be determined. Our study examines this association in ischemic stroke patients. Methods. One hundred and seventy consecutive ischemic stroke or transient ischemic attack (TIA) patients were included. All patients underwent brain computed tomography (CT) with assessment of the extension and severity of WMCs, carotid arteries duplex scan with measurements of intima-media thickness (IMT) and plaques. Results. Seventy-two patients (42.4%) were found to have white matter lesions, of whom 28.8% had advanced LA. Mean IMT was significantly higher in patients with LA and with advanced LA (P = 0.002, P = 0.003, resp.). In addition, LA and LA severity were associated with existence of carotid plaque (P = 0.007, P = 0.004, resp.). In multivariate logistic regression analysis, including all vascular risk factors, LA was found to be associated with age and IMT. Conclusion. This study reinforces the tight association between LA and carotid atherosclerosis in ischemic stroke patients. We conclude that a chronic atherosclerotic disease underlies the pathophysiology of leukoaraiosis and its progression.

Abstract
Dysarthria is a speech disorder associated with impairments of intelligibility, smoothness, loudness, and clarity of articulations. Dysarthria involves disability of reproducing various physical, tonal, and sound features of speech sounds in oral speech; unintelligible and slurred articulation with swallowing of sounds is characteristic. Articulatory movements and speech are slow, patients complain to the sensations of a 'thick' tongue and 'porridge' in the mouth. Patients'phrases are constructed correctly, vocabulary is not affected, and the grammatical structure of words is preserved. Reading, writing, internal speech, and understanding of speech are unaffected. Several types of dysarthria have been described on the basis of the lesion locations. Dysarthria can be associated with lacunar syndromes as well. Mutism represents a condition when patient cannot speak and answer the questions, but remains conscious and is able to produce written speech.

Abstract
OBJECTIVE Although typically linked to aging, small vessel disease (SVD) is also observed in younger adult patients, with common vascular risk factors (RF). We aimed to investigate features of SVD occurrence at an early adult age. PATIENTS AND METHODS Vascular RF, functional and cognitive status and severity of lesions on MRI expressed as total score on Age-Related White Matter Changes (ARWMC) scale were analyzed in 200 consecutive patients with cerebral SVD admitted to a tertiary neurological hospital. Variables were compared between younger (35-55 years) and older (>56 years) patients. RESULTS In this study, 63 (31.5%) of patients were 55 years or younger. Both age groups had comparable RF profiles, but smoking emerged as an independent predictor for SVD at a younger age (OR 2.9; 95% CI 1.5-5.5; p=0.002). Younger patients had better functional (OR 1.8; 95% CI 1.3-2.5; p=0.0001) and cognitive (χ(2) 13.94; p=0.0009) status compared to older patients. However, two thirds of younger patients had some degree of cognitive deficit. Total score on ARWMC scale was lower in younger patients (mean 12.3 in younger versus 15.2 in older, OR 1.11; 95% CI 1.0-1.18; p=0.001). There was a strong correlation in both groups between functional score, cognitive status and ARWMC score (p<0.0001). CONCLUSION In our dataset, younger patients with SVD shared common vascular RF with older patients. In the group aged ≤55, better functional and cognitive status and less severe MRI changes were noted. However, a substantial number of younger SVD patients presenting with TIA or ischemic stroke had various deficits.

Abstract
OBJECTIVES/PURPOSES Small vessel disease (SVD) is associated with traditional vascular risk factors (RF). The aim of our study was to determine whether different SVD types, single lacunar infarction (LI) and multiple LI (MLI) with or without white matter lesions (WML), have different RF profiles. PATIENTS AND METHODS Forty RF parameters were analysed in 201 consecutive patients with magnetic resonance imaging finding of SVD. RESULTS History of arterial hypertension, higher systolic and mean blood pressure (BP) but also hypotension, and higher plasma homocysteine levels were more frequent in MLI compared to single LI patients (p<0.05). Patients with one LI were younger, more frequently had clinically evident stroke and family history of cardiovascular disease (CVD) (p<0.05). Significant difference between groups was found only in these RF, indicating that similar pathological processes led to both types of SVD. CONCLUSION Positive correlation with age and family history of CVD necessitates further analyses of other factors, predominantly genetic, as the key to the answer why patients develop different lesions in SVD.

Abstract
BACKGROUND Cerebral small vessel disease is rarely described in association with pseudoxanthoma elasticum (PXE), a hereditary connective tissue disorder with skin, eye and vascular manifestations. This autosomally inherited elastic tissue disease has been attributed to mutations in the ABCC6 gene located on chromosome 16p13.1. Different stroke mechanisms are suggested in PXE patients, arterial hypertension and accelerated atherosclerosis being the leading ones. CASE DESCRIPTIONS Case 1: A 49-year-old man with history of mild hypertension presented with recurrent transient ischemic attacks. At the age of 42, evaluation for progressive visual loss and skin changes led to diagnosis of PXE. Brain magnetic resonance imaging (MRI) disclosed multiple lacunar infarctions and confluent periventricular white matter lesions (WML). Case 2: A 71-year-old woman with history of mild hypertension suffered right-sided stroke. Diagnosis of PXE was made at the age of 48 due to severe visual loss and skin changes. Brain MRI revealed multiple lacunar infarctions and subcortical ischemic leukoencephalopathy. Case 3: A 47-year-old woman with prominent skin changes and bilateral amblyopia developed right-sided weakness. Skin biopsy confirmed PXE. Several lacunar infarcts in deep white matter and pons were revealed on MRI. DISCUSSION We present three patients with clinical and histopathological features of PXE who presented with multiple lacunar strokes, two with extensive confluent WML. These cases illustrate that PXE is a rare but significant risk factor for small vessel disease and stroke in patients of all age groups. Occlusive small vessel disease and subsequent lacunar infarcts and WML represent important PXE manifestations.
