The possible role of oxidative stress marker glutathione in the assessment of cognitive impairment in multiple sclerosis.

Oxidative stress markers have a distinct role in the process of demyelination in multiple sclerosis. This study investigated the potential correlation of markers of oxidative stress (glutathione [GSH], catalase) with the number of demyelinating lesions and the degree of disability, cognitive deficit, and depression in patients with relapsing-remitting multiple sclerosis (RRMS). Sixty subjects meeting the criteria for RRMS (19 men and 41 women), and 66 healthy controls (24 men, 42 women) were included. In this study, GSH significantly negatively correlated with the degree of cognitive impairment. This is the first study of subjects with RRMS that performed the mentioned research of serum GSH levels on the degree of cognitive damage examined by the Montreal Scale of Cognitive Assessment (MoCA) test. The development of cognitive changes, verified by the MoCA test, was statistically significantly influenced by the positive number of magnetic resonance lesions, degree of depression, expanded disability status scale (EDSS), age, and GSH values. Based on these results, it can be concluded that it is necessary to monitor cognitive status early in RRMS patients, especially in those with a larger number of demyelinating lesions and a higher EDSS level and in older subjects. Also, the serum level of GSH is a potential biomarker of disease progression, which could be used more widely in RRMS.

Updated Perspectives on Lifestyle Interventions as Secondary Stroke Prevention Measures: A Narrative Review.

Despite being highly preventable, stroke is the second-most common cause of death and disability in the world. Secondary prevention is critical as the stroke recurrence risk is 6- to 15-fold higher than the risk of stroke in the general population. Stroke recurrence is associated with higher mortality rates and increased disability levels. Lifestyle modifications should address not single but multiple cardiovascular risk factors to effectively reduce the risk of stroke. Lifestyle modifications on a personal level should include adequate physical activity, a healthy diet, the cessation of smoking and alcohol consumption, and stress reduction. Physical activities should be performed in a healthy environment without air pollution. According to recent studies, up to 90% of strokes might be prevented by addressing and treating ten modifiable stroke risk factors, half of which are related to lifestyle modifications. These lifestyle modifications, which are behavioral interventions, could impact other modifiable risk factors such as arterial hypertension, hyperlipidemia, obesity, diabetes, and atrial fibrillation. The most common obstacles to effective secondary stroke prevention are motor impairment, post-stroke cognitive impairment, post-stroke depression, and stroke subtype. Long-term lifestyle modifications are difficult to sustain and require comprehensive, individualized interventions. This review underlines the benefits of adhering to lifestyle modifications as the most effective secondary stroke prevention measure.

Creative therapy in health and disease: Inner vision.

Can we better understand the unique mechanisms of de novo abilities in light of our current knowledge of the psychological and neuroscientific literature on creativity? This review outlines the state-of-the-art in the neuroscience of creativity and points out crucial aspects that still demand further exploration, such as brain plasticity. The progressive development of current neuroscience research on creativity presents a multitude of prospects and potentials for furnishing efficacious therapy in the context of health and illness. Therefore, we discuss directions for future studies, identifying a focus on pinpointing the neglected beneficial practices for creative therapy. We emphasize the neglected neuroscience perspective of creativity on health and disease and how creative therapy could offer limitless possibilities to improve our well-being and give hope to patients with neurodegenerative diseases to compensate for their brain injuries and cognitive impairments by expressing their hidden creativity.

Stroke Scales as Assessment Tools in Emergency Settings: A Narrative Review.

In the last 20 years, substantial improvements have been made in stroke recanalization treatment. Good outcomes after modern reperfusion treatment require the rapid and accurate identification of stroke patients. Several stroke rating scales are available or have been proposed for the early recognition of stroke and the evaluation of stroke severity and outcome. This review aims to provide an overview of commonly used stroke scales in emergency and clinical settings. The most commonly used scale in a prehospital setting for stroke recognition is the Face, Arms, Speech, Time (FAST) test. Among many prehospital stroke scales, the Los Angeles Prehospital Stroke Screen has the highest sensitivity and specificity for confirming stroke diagnosis. The National Institutes of Health Stroke Scale (NIHSS) is the most recommended tool for the evaluation of stroke patients in hospital settings and research, and it has two variants: the shortened NIHSS for Emergency Medical Service and the modified NIHSS. The evaluation of comatose patients usually involves assessment with the Glasgow Coma Scale, which is very useful in patients with hemorrhagic stroke or traumatic brain injury. In patients with subarachnoid hemorrhage, the outcome is usually accessed with the Hunt and Hess scale. A commonly used tool for stroke outcome evaluation in clinical/hospital settings and research is the modified Rankin scale. The tools for disability evaluation are the Barthel Index and Functional Independence Measure.

The role of thyroid hormones in carotid arterial wall remodeling in women.

Introduction: Thyroid hormones affect the cardiovascular system, but the precise mechanisms of their effects on the development of atherosclerosis are not entirely clear. The relationship between subclinical hypothyroidism, dyslipidemia and carotid atherosclerosis has been widely investigated, but the findings were controversial. The aim of the present study was to determine whether female subjects with subclinical hypothyroidism (SHypo) have increased carotid intima-media thickness (IMT) compared with euthyroid subjects, as well as to examine the association of SHypo, carotid atherosclerosis and dyslipidemia.Methods: This research included 100 women aged 30 to 70 years who were divided into two groups: the SHypo group including subjects with signs of subclinical hypothyroidism and the control group of euthyroid subjects. Carotid IMT thickness using B mode ultrasound was determined and its correlation with serum concentrations of fT4, TSH, CRP, and lipid profile including small dense LDL (sdLDL) was analysed.Results: Subjects with SHypo had significantly increased carotid IMT (IMT ≥ 75th centile) in all three measured segments of the right (p <0.001) and the left (p = 0.001) carotid artery compared to the control group, with a significantly more frequent appearance of plaque (25% vs. 9%; p = 0.05). Significant positive correlations were found between higher TSH and higher IMT values. Increased age, LDL cholesterol, and TSH predicted thickening of the carotid artery IMT.Conclusions: It is important to screen people showing early, subclinical signs of thyroid gland dysfunction due to its impact on carotid atherosclerosis development.

Comorbidity from a Neuropsychiatric Perspective.

Comorbidity in neurology and psychiatry involves the onset of a mental illness with the simultaneous presence of a neurological disorder or other illness. The degree of comorbidity of mental and neurological disorders is unexpectedly high. In addition to the direct connection and simultaneous occurrence of mental and neurological illness, the indirect impact of mental illness on the occurrence of neurological problems is even more significant. This link is realized through the influence of mental illness on risk factors for the development of cerebrovascular and cardiovascular diseases. Their incidence is higher in the psychiatric population than in the general population. Numerous studies have confirmed that risk factors for cerebrovascular disease (hypertension, hyperlipidemia, diabetes mellitus, etc.) are more common among patients with mental disorders than in the general population. Also, research shows that patients with mental disorders are less frequently controlled, have less control over risk factors, and that numerous comorbidities are detected later or remain undetected. Given that cerebrovascular and cardiovascular diseases represent one of the most important public health and socioeconomic problems of today, both in the world and in Croatia, this problem should not remain in the shadow.

THE VALUE OF BLINK REFLEX IN EARLY DIAGNOSIS OF MULTIPLE SCLEROSIS.

The aim was to determine differences of blink reflex in clinically definite multiple sclerosis (CDMS) and clinically isolated syndrome (CIS) in patients presented with symptoms and signs of brainstem impairment. The study included 20 patients diagnosed with CDMS, 20 with CIS, and 20 healthy controls. We recorded latencies of early (R1) and late component ipsilaterally (R2) and contralaterally (R2'), and occurrence of irritative component (R3). We analyzed data on sex, age, signs of brainstem impairment and magnetic resonance imaging (MRI) findings for the presence of brainstem demyelinating lesions. There was no statistically significant difference between patient groups according to sex, age, symptoms of brainstem involvement and MRI findings. There was no statistically significant difference in R1 component latencies and R2 latencies on the right side. Latencies of R2 on the left and R2' on the right were statistically longer in CDMS group. There was no difference in the appearance of R3 component. In conclusion, blink reflex was found to be a very sensitive and useful diagnostic tool in the assessment of brainstem structures, especially because abnormalities are seen not only in CDMS but also in CIS. Slowing of the late component as a sign of dysfunction in the efferent part of the reflex arc is not very specific but is a highly sensitive finding.

Antithrombotic therapy in patients with non-traumatic intracerebral haemorrhage and atrial fibrillation: A retrospective study.

INTRODUCTION: The aim of the study was to determine the outcome, prescribed therapy, and localization of non-traumatic intracerebral haemorrhage in patients with atrial fibrillation. PATIENTS AND METHODS: This retrospective study enrolled patients with atrial fibrillation hospitalised for non-traumatic intracerebral haemorrhage from 2004 to 2013. We compared the patients according to previous antithrombotic therapy, demographics, previous CHADS2 score, comorbidities, the international normalised ration, localisation of intracerebral hamorrhage, stroke severity, prescribed antithrombotic therapy and outcome. RESULTS: A total of 85 patients were enrolled and assigned to an AT+ group (n = 49; 14 on aspirin, 35 on warfarin) and an AT- group (n = 36; without antithrombotic therapy prior to hospitalisation). The latter had a lower proportion of known atrial fibrillation (90% vs 47%, P < 0.001). The mean INR was 2.6 ± 1.5. The in-hospital mortality rates in both groups were high: 43% in AT+ group and 47% in AT- group. There were no significant differences in any of the predefined comparisons. CONCLUSION: Treating patients with intracerebral haemorrhage and atrial fibrillation is challenging due to higher mortality rates and issues regarding the use of antithrombotic treatment in stroke prevention. Based on our data, prior antithrombotic therapy was not associated with increased in-hospital mortality rates or poorer functional outcome at hospital discharge in comparison with no prior antithrombotic therapy.

Genetic and lifestyle predictors of ischemic stroke severity and outcome.

BACKGROUND: Different models that include clinical variables and blood markers have been investigated to predict acute ischemic stroke treatment course and recovery. AIM: The aim of the study was to investigate associations between lipid levels, lifestyle factors, hemostatic (F5, F2, SERPINE1, F13A1, and FGB), and atherogenic (APOA5 and ACE) gene variants and acute ischemic stroke (AIS) severity. MATERIALS AND METHODS: This study included 250 patients with AIS in which F5, F2, SERPINE1, F13A1, FGB, APOA5, and ACE genotypes were determined. Total cholesterol (TC), high-density cholesterol, low-density cholesterol, and triglycerides concentrations were measured within 24 h of the AIS onset. Examination of the neurological deficit was done using National Institutes of Health Stroke Scale/Score (NIHSS). RESULTS: APOA5 genotype [TC + CC] was more frequent (P = 0.026) in patients with the NIHSS score ≥ 21. Univariate regression analysis has shown that triglycerides (OR 0.55, 95% CI 0.34-0.91; P = 0.019), obesity (0.28, 95% CI 0.10-0.73; P = 0.010), age (OR 1.08, 95% CI 1.04-1.13; P < 0.001), and APOA5 genotype (TC + CC) (OR 2.40, 95% CI 1.10-5.25; P = 0.034) are significantly associated with a severe stroke. When all variables were included in model age (OR 1.06, 95% CI 1.01-1.11; P = 0.018), obesity (OR 0.25, 95% CI 0.08-0.77; P = 0.016) and APOA5 genotype (TC + CC) (OR 3.26, 95% CI 1.29-8.23; P = 0.012) remained significant for the risk of severe AIS. CONCLUSION: APOA5 genotype (TC + CC), age, and obesity could be used as prognostic risk factors for a very severe stroke (NIHSS ≥ 21).

Possibilities of Dementia Prevention - It is Never Too Early to Start.

Dementia represents one of the greatest global challenges for health and social care in this century. More than 50 million people worldwide suffer from dementia, and this number is predicted to triple by 2050. Ageing is often associated with cognitive impairment. Therefore, prevention of cognitive impairment is an imperative. Dementia includes a heterogeneous group of disorders, the most common being Alzheimer's disease and vascular dementia. Most cardiovascular risk factors such as hypertension, diabetes mellitus, hypercholesterolemia, atrial fibrillation and smoking are not exclusive risk factors for vascular dementia but also for Alzheimer's disease. The ApoE4 allele is the single non-modifiable risk factor for Alzheimer's disease. Today we know that an important, modifiable risk factor is education. Better education means better protection against dementia. A large number of dementia cases are potentially preventable by early intervention. Early changes in the blood vessel wall can be detected by early ultrasound methods or early biomarkers. These methods allow us to detect changes before the disease becomes clinically evident. Early disease detection enables timely management, and studies have shown that careful control of vascular risk factors can postpone the onset or even reverse disease progression.

Use of Multiple Ultrasonographic Parameters in Confirmation of Carpal Tunnel Syndrome.

OBJECTIVES: Ultrasonography (US) of the median nerve has been increasingly studied and used for confirmation of carpal tunnel syndrome (CTS). However, a consensus on the choice of parameters to be evaluated is still not established. The aim of this diagnostic accuracy study was to assess the diagnostic value of multiple parameters individually, as well as in different combinations of variable complexity, and to find an optimal approach for US-based confirmation of a CTS diagnosis. METHODS: All participants completed clinical and electrophysiologic evaluations, and their hands were scanned with a 5-13-MHz linear US transducer. Eighty-six patients with CTS (135 symptomatic hands) and 50 control participants (93 asymptomatic hands) were analyzed. The median nerve was recorded transversely at the forearm, at the carpal tunnel inlet, in the mid tunnel, and at the carpal tunnel outlet. For determining the parameters' diagnostic value, sensitivities, specificities, and area under the curve (AUC) values were calculated. RESULTS: The inlet cross-sectional area, inlet circumference, and outlet cross-sectional area of the median nerve had the highest AUCs (0.962, 0.920, and 0.913, respectively), sensitivities (87.4%, 80.0%, and 74.1%), and specificities (94.6%, 91.4%, and 92.5%) among single-measurement parameters. An analysis of 2-level parameters (wrist-to-forearm-ratio, inlet-to-outlet-ratio, outlet-to-forearm-ratio, and inlet-outlet mean) yielded the highest AUC (0.974) for the mean cross-sectional area of the median nerve [(inlet + outlet cross-sectional area)/2], with high sensitivity (93.5%) and specificity (91.1%). A compound regression-based index yielded a marginally higher AUC (0.989) than the previously mentioned parameters. CONCLUSIONS: Results of the study show that the mean cross-sectional area and inlet cross-sectional area may be valid and easy-to-acquire parameters for routine clinical use in confirming CTS.

Dyslipidemia in subclinical hypothyroidism requires assessment of small dense low density lipoprotein cholesterol (sdLDL-C).

BACKGROUND: Usually both hypothyroidism and hyperthyroidism are related to the cardiovascular and cerebrovascular disease development. The relationship between subclinical hypothyroidism has been widely investigated but the findings remain controversial. The aim of the present study was to evaluate the lipid profile in patients with subclinical hypothyroidism (SHypo) in comparison to controls and to determine the association of SHypo and dyslipidemia in attempt to find importance of small dense low-density lipoprotein cholesterol (sdLDL-C) in atherosclerosis. MATERIAL AND METHODS: In this study we included 100 women, aged 30 to 70 years that were divided into subgroups according to their age. According to the values of levels of thyroid hormones they were divided into euthyroid (control) group (n = 64) and (newly discovered) subclinical hypothyroidism (SHypo) group (n = 36). A high-sensitivity C-reactive protein (hs-CRP) and lipid profile, including small dense low-density lipoprotein cholesterol (sdLDL-C) were determined. Body weight and height were measured and BMI calculated. History of the current illness, medication, alcohol consumption and cigarettes smoking were noted. RESULTS: Changed lipid profile as well as elevated triglycerides and sdLDL-C were observed in the group with subclinical hypothyroidism compared to the control group. CONCLUSIONS: It is important to determine serum lipid levels, especially serum sdLDL-C levels at an early stage of subclinical hypothyroidism, since they represent atherogenic LDL particles and are better indicators for dyslipidaemia in subclinical hypothyroidism and the development of atherosclerosis with potential complications such as cardiovascular and cerebrovascular diseases.

Efficacy and safety of Ginkgo biloba standardized extract in the treatment of vascular cognitive impairment: a randomized, double-blind, placebo-controlled clinical trial.

OBJECTIVES: The aim of this randomized, double-blind, placebo-controlled trial was to determine the efficacy and safety of Ginkgo biloba extract in patients diagnosed with vascular cognitive impairment (VCI). METHODS: A total of 90 patients (aged 67.1±8.0 years; 59 women) were randomly allocated (1:1:1) to receive G. biloba 120 mg, G. biloba 60 mg, or placebo during a 6-month period. Assessment was made for efficacy indicators, including neuropsychological tests scores (Sandoz Clinical Assessment Geriatric Scale, Folstein Mini-Mental State Examination, Mattis Dementia Rating Scale, and Clinical Global Impression) and transcranial Doppler ultrasound findings. Safety indicators included laboratory findings, reported adverse reactions, and clinical examination. RESULTS: At the end of 6-month study period, G. biloba 120 and 60 mg showed a statistically significant positive effect in comparison with placebo only on the Clinical Global Impression score (2.6±0.8 vs 3.1±0.7 vs 2.8±0.7, respectively; P=0.038). The Clinical Global Impression score showed a significant deterioration from the baseline values in the placebo group (-0.3±0.5; P=0.021) as opposed to G. biloba groups. No significant differences were found in the transcranial Doppler ultrasound findings. Adverse reactions were significantly more common and serious in the placebo group (16 subjects) than in either of the two G. biloba extract groups (eight and nine subjects, respectively), whereas laboratory findings and clinical examinations revealed no differences between the groups receiving G. biloba extract and placebo. CONCLUSION: According to our results, G. biloba seemed to slow down the cognitive deterioration in patients with VCI, but the effect was shown in only one of the four neuropsychological tests administered. However, because of this mild effect in combination with a few adverse reactions, we cannot say that it is ineffective or unsafe either. Further studies are still needed to provide unambiguous evidence on the efficacy and safety of G. biloba extract.

Intravenous thrombolysis for ischemic stroke in the golden hour: propensity-matched analysis from the SITS-EAST registry.

As there are scarce data regarding the outcomes of acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) within 60 min from symptom onset ("golden hour"), we sought to compare outcomes between AIS patients treated within [GH(+)] and outside [GH(-)] the "golden hour" by analyzing propensity score matched data from the SITS-EAST registry. Clinical recovery (CR) at 2 and 24 h was defined as a reduction of ≥10 points on NIHSS-score or a total NIHSS-score of ≤3 at 2 and 24 h, respectively. A relative reduction in NIHSS-score of ≥40% at 2 h was considered predictive of complete recanalization (CREC). Symptomatic intracranial hemorrhage (sICH) was defined using SITS-MOST criteria. Favorable functional outcome (FFO) was defined as a mRS-score of 0-1 at 3 months. Out of 19,077 IVT-treated AIS patients, 71 GH(+) patients were matched to 6882 GH(-) patients, with no differences in baseline characteristics (p > 0.1). GH(+) had higher rates of CR at 2 (31.0 vs. 12.4%; p < 0.001) and 24 h (41 vs. 27%; p = 0.010), CREC at 2 h (39 vs. 21%; p < 0.001) and FFO (46.5 vs. 34.0%; p = 0.028) at 3 months. The rates of sICH and 3-month mortality did not differ (p > 0.2) between the two groups. GH(+) was associated with 2-h CR (OR: 5.34; 95% CI 2.53-11.03) and CREC (OR: 2.38; 95% CI 1.38-4.09), 24-h CR (OR: 1.88; 95% CI 1.08-3.26) and 3-month FFO (OR: 2.02; 95% CI 1.15-3.54) in multivariable logistic regression models adjusting for potential confounders. In conclusion, AIS treated with IVT within the GH seems to have substantially higher odds of early neurological recovery, CREC, 3-month FFO and functional improvement.

Arts, Brain and Cognition.

Art is a product of human creativity; it is a superior skill that can be learned by study, practice and observation. Modern neuroscience and neuroimaging enable study of the processes during artistic performance. Creative people have less marked hemispheric dominance. It was found that the right hemisphere is specialized for metaphoric thinking, playfulness, solution finding and synthesizing, it is the center of visualization, imagination and conceptualization, but the left hemisphere is still needed for artistic work to achieve balance. A specific functional organization of brain areas was found during visual art activities. Marked hemispheric dominance and area specialization is also very prominent for music perception. Brain is capable of making new connections, activating new pathways and unmasking secondary roads, it is "plastic". Music is a strong stimulus for neuroplasticity. fMRI studies have shown reorganization of motor and auditory cortex in professional musicians. Other studies showed the changes in neurotransmitter and hormone serum levels in correlation to music. The most prominent connection between music and enhancement of performance or changing of neuropsychological activity was shown by studies involving Mozart's music from which the theory of "The Mozart Effect" was derived. Results of numerous studies showed that listening to music can improve cognition, motor skills and recovery after brain injury. In the field of visual art, brain lesion can lead to the visuospatial neglect, loss of details and significant impairment of artistic work while the lesions affecting the left hemisphere reveal new artistic dimensions, disinhibit the right hemisphere, work is more spontaneous and emotional with the gain of artistic quality. All kinds of arts (music, painting, dancing...) stimulate the brain. They should be part of treatment processes. Work of many artists is an excellent example for the interweaving the neurology and arts.

Intravenous Thrombolysis for Stroke Recurring Within 3 Months From the Previous Event.

BACKGROUND AND PURPOSE: According to the European license, alteplase can be given no sooner than 3 months after previous stroke. However, it is not known whether past history of stroke influences the effect of treatment. Our aim was to evaluate safety and functional outcome after intravenous thrombolysis administered in everyday practice to patients with previous stroke≤3 months compared with those with first-ever stroke. METHODS: We analyzed consecutive cases treated with alteplase between October 2003 and July 2014 contributed to the Safe Implementation of Thrombolysis for Stroke-Eastern Europe registry from 12 countries. Odds ratios were calculated using unadjusted and adjusted logistic regression. RESULTS: Of 13,007 patients, 11,221 (86%) had no history of stroke and 249 (2%) experienced previous stroke≤3 months before admission. Patients with previous stroke≤3 months had a higher proportion of hypertension and hyperlipidemia. There were no significant differences in outcome, including symptomatic intracerebral hemorrhage according to European Cooperative Acute Stroke Study (unadjusted odds ratio 1.27, 95% confidence interval: 0.74-2.15), and being alive and independent at 3 months (odds ratio 0.81, 95% confidence interval: 0.61-1.09). CONCLUSIONS: Patients currently treated with alteplase, despite a history of previous stroke≤3 months, do not seem to achieve worse outcome than those with first-ever stroke. Although careful patient selection was probably of major importance, our findings provide reassurance that this group of patients may safely benefit from thrombolysis and should not be arbitrarily excluded as a whole. Further studies are needed to identify the shortest safe time lapse from the previous event to treatment with alteplase.

Management of ischemic stroke in Central and Eastern Europe.

Stroke is one of the leading causes of disability in Europe. Central and Eastern European countries have the highest incidence and mortality rates through Europe. The improvements in stroke prevention and treatment in Central and Eastern European countries did not completely reach the quality parameters present in Western European countries. We present features of current management of stroke in Central and Eastern European countries.

Safety of Statin Pretreatment in Intravenous Thrombolysis for Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: A recent meta-analysis investigating the association between statins and early outcomes in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) indicated that prestroke statin treatment was associated with increased risk of 90-day mortality and symptomatic intracranial hemorrhage. We investigated the potential association of statin pretreatment with early outcomes in a large, international registry of AIS patients treated with IVT. METHODS: We analyzed prospectively collected data from the Safe Implementation of Treatments in Stroke-East registry (SITS-EAST) registry on consecutive AIS patients treated with IVT during an 8-year period. Early clinical recovery within 24 hours was defined as reduction in baseline National Institutes of Health Stroke Scale score of ≥10 points. Favorable functional outcome at 3 months was defined as modified Rankin Scale scores of 0 to 1. Symptomatic intracranial hemorrhage was diagnosed using National Institute of Neurological Disorders and Stroke, European-Australasian Acute Stroke Study-II and SITS definitions. RESULTS: A total of 1660 AIS patients treated with IVT fulfilled our inclusion criteria. Patients with statin pretreatment (23%) had higher baseline stroke severity compared with cases who had not received any statin at symptom onset. After adjusting for potential confounders, statin pretreatment was not associated with a higher likelihood of symptomatic intracranial hemorrhage defined by any of the 3 definitions. Statin pretreatment was not related to 3-month all-cause mortality (odds ratio, 0.92; 95% confidence interval, 0.57-1.49; P=0.741) or 3-month favorable functional outcome (odds ratio, 0.81; 95% confidence interval, 0.52-1.27; P=0.364). Statin pretreatment was independently associated with a higher odds of early clinical recovery (odds ratio, 1.91; 95% confidence interval, 1.25-2.92; P=0.003). CONCLUSIONS: Statin pretreatment seems not to be associated with adverse outcomes in AIS patients treated with IVT. The effect of statin pretreatment on early functional outcomes in thrombolysed AIS patients deserves further investigation.
