Abstract
INTRODUCTION Individuals with dementia are underrepresented in interventional studies for acute ischemic stroke (AIS). This research gap creates a bias against their treatment in clinical practice. Our goal was to compare the safety and efficacy of intravenous-thrombolysis (t-PA) and endovascular treatment (EVT) in individuals with or without pre-AIS dementia. METHOD A retrospective study of AIS patients receiving t-PA or EVT between 2019 and 2022. Patients were classified as dementia on a case-by-case review of baseline assessment. Additional variables included demographic, vascular risk factors, AIS severity and treatment. Outcomes of interest were intracerebral hemorrhage, mortality in 90-days, and the difference in modified rankin scale (mRS) before AIS and in 90-days follow-up. Outcomes were compared across non-matched groups and following propensity-score matching. RESULTS Altogether, 628 patients were included, of which 68 had pre-AIS dementia. Compared to non-dementia group, dementia group were older, had a higher rate of vascular risk factors, higher pre-stroke mRS and higher baseline NIHSS. Individuals with dementia had higher rates of mortality (25% vs.11%,p < 0.01) on non-matched comparison. All cohort and restricted t-PA EVT matched analysis showed no difference in any outcome. Regression analysis confirmed that AIS severity at presentation and its treatment, not dementia, were the chief contributors to patients' outcomes. DISCUSSION Our results indicate that pre-AIS dementia does not impact the efficacy or safety of EVT or t-PA for AIS. We thus call for more inclusive research on stroke therapy with regards to baseline cognitive status. Such studies are urgently required to inform stroke guidelines and enhance care.

Abstract
The prevalence of headache in stroke has been reported between 8% and 34%. Determining the prevalence, features, and effects on prognosis of cerebellar ischemic strokes that presented with headache solely and/or with other cerebellar signs were the aims of our study.All patients diagnosed with cerebellar ischemia were included. Electronic medical records were reviewed. Patients have been followed up for 6th month. Descriptive statistics were generated. A total of 4763 patients were evaluated retrospectively, 200 patients had cerebellar ischemia and 22 patients of these cerebellar ischemias (11%) had a headache at initial presentation. Ataxia, dysarthria, dysmetria were the most common neurological findings. There was no significant difference whether ischemic lesion single or multiple and whether above or below 1.5 cm diameter. Ischemic lesions generally were in cortical/ juxtacortical layer. According to vascular perfusion areas, 54.5% patients' ischemia was located in PICA (posterior inferior cerebellar artery) territory. Patients presenting with a headache, predominantly had left hemispheric (vermian > hemispheric > pedincular) involvement. Although these patients generally had high modified Rankin Scale scores at the first evaluation, they had low NIHSS (National Institutes of Health Stroke Scale) scores (0-5), and nearly all patients recovered, with low mRS at the 6-month follow-up.Cerebellar ischemic strokes with headache presentation are significantly prevalent in patients with left hemispheric, cortical/juxtacortical, PICA perfusion territory ischemias and are associated with low morbidity unless there was a conscious disorder. We believe this is one of the first studies that evaluated the clinical and radiological parameters of cerebellar stroke patients with headache.

Abstract
INTRODUCTION Neurosarcoidosis is associated with a significant degree of morbidity and mortality and its treatments are varied and complex. There is a paucity of information in current literature on patterns of treatment and long term outcomes. This study aimed to evaluate the clinical outcomes and responses to immunosuppressive therapy in a large cohort of neurosarcoidosis patients . METHODS We enrolled 80 patients with a diagnosis of neurosarcoidosis. Prescription patterns and clinical outcomes before and after treatment and differences between the treatment groups were compared using Kruskal-Wallis and Mann-Witney U tests. RESULTS Patients with cranial mononeuropathy other than optic neuropathy were more likely to be treated with steroids alone whereas patients with other presentations were likely to require second and third level treatments. These included azathioprine, methotrexate, mycophenolate, infliximab, and cyclophosphamide often used in combination. Prednisolone alone at onset failed in 67% of patients but appeared most effective in those with isolated facial nerve palsy. Patients treated with prednisolone plus a standard immunosuppression first line generally did well except for those with brain parenchymal disease and /or hydrocephalus who responded better to the addition of infliximab, or cyclophosphamide. Triple therapy with prednisolone + azathioprine + infliximab was associated with significantly greater improvement on the Modified Rankin Scale than prednisolone alone whether used first line (p = 0.001 corrected) or subsequently (p = 0.021 corrected). Overall favourable outcomes in the form of improvement of MRS were reported in 87%, CONCLUSIONS: Our results provides evidence that early immunosuppressive treatments, with azathioprine, methotrexate and infliximab could effectively improve clinical outcomes in many patients with neurosarcoidosis.
