Twitter is a free, open access social media platform that is widely used in medicine by physicians, scientists, and patients. It provides an opportunity for advocacy, education, and collaboration. However, it is likely not utilized to its full advantage by many disciplines in medicine, and pitfalls exist in its use. In particular, there has not been a review of Twitter use and its applications in the field of neurology. This review seeks to provide an understanding of the current use of Twitter in the field of neurology to assist neurologists in engaging with this potentially powerful application to support their work.

Introduction Two pharmacological possibilities exist for an acute ischemic stroke (AIS): recanalization of the occluded artery and neuroprotection from ischaemic injury, the latter’s efficacy being debatable. We sought to determine whether administration of Citicoline immediately after recanalization therapy for AIS would improve clinical and radiological outcome at three months compared to standard treatment alone. Patients and methods CAISR was a single centre, randomized, placebo-controlled, parallel-group trial with blinded endpoint assessment. It was approved by the All India Institute of Medical Sciences Institutional ethics committee and registered at the Clinical Trial Registry of India (CTRI/2018/011900). We recruited participants with AIS undergoing recanalization therapy and randomly assigned them to receive either Citicoline or placebo in 1:1 ratio. Citicoline arm patients received Citicoline 1gm BD intravenously for three days, followed by oral citicoline 1gm BD for 39 days. Placebo arm patients received 100ml intravenous normal saline for three days, followed by multivitamin tablet BD for 39 days. All patients received standard of care. Outcome Blinded assessors did the follow-up assessment at six weeks (MRI Brain-stroke volume) and three months (NIHSS 0–2, mRS 0–2 and Barthel index> = 95). Results The infarct volume decreased from week 1 to week 6 by 2.6 cm3 on placebo versus 4.2 cm3 on Citicoline (p-0.483). The OR for achieving NIHSS 0–2, mRS 0–2 and Barthel index> = 95 with Citicoline was found to be 0.96(95%CI 0.39–2.40), 0.92(95%CI 0.40–2.05) and 0.87(95%CI 0.22–2.98) respectively. Conclusion CAISR was the first to evaluate the role of Citicoline, when used immediately after recanalization therapy, when the penumbral tissue is the most susceptible either to be protected from injury or become ischemic. We did not find any significant difference between the Citicoline or placebo arms with respect to either our primary or secondary outcomes.

Background As the health systems around the world struggled to meet the challenges of COVID-19 pandemic, care of many non-COVID emergencies was affected. Aims The present study examined differences in the diagnosis, evaluation and management of stroke patients during a defined period in the ongoing pandemic in 2020 when compared to a similar epoch in year 2019. Methods The COVID stroke study group (CSSG) India, included 18 stroke centres spread across the country. Data was collected prospectively between February and July 2020 and retrospectively for the same period in 2019. Details of demographics, stroke evaluation, treatment, in-hospital and three months outcomes were collected and compared between these two time points. Results A total of 2549 patients were seen in both study periods; 1237 patients (48.53%) in 2019 and 1312 (51.47%) in 2020. Although the overall number of stroke patients and rates of thrombolysis were comparable, a significant decline was observed in the month of April 2020, during the initial period of the pandemic and lockdown. Endovascular treatment reduced significantly and longer door to needle and CT to needle times were observed in 2020. Although mortality was higher in 2020, proportion of patients with good outcome were similar in both the study periods. Conclusions Although stroke admissions and rates of thrombolysis were comparable, some work flow metrics were delayed, endovascular stroke treatment rates declined and mortality was higher during the pandemic study period. Reorganization of stroke treatment pathways during the pandemic has likely improved the stroke care delivery across the globe.

Primary CNS Vasculitis (PCNSV) is a rare inflammatory disorder affecting the blood vessels of the central nervous system. Patients present with a combination of headaches, seizures, and focal neurological deficits. There is usually a diagnostic delay. Treatment is based on observational studies and expert opinion. Our objective was to identify clinical, laboratory, neuroimaging, pathologic or management-related associations with 2 year outcome in patients with primary CNS vasculitis. We conducted a cohort study at a single tertiary care referral centre of prospectively (2018-2019) and retrospectively (2010-2018) identified individuals with primary CNS vasculitis (diagnosis was proven by either brain biopsy or cerebral digital subtraction angiography). Clinical, imaging and histopathologic findings, treatment, and functional outcomes were recorded. Univariate and stepwise multiple logistic regression were applied. P-value<0.05 was considered statistically significant. The main outcome measures were documentation of clinical improvement or worsening (defined by mRS scores) and identification of independent predictors of good functional outcome (mRS 0-2) at 2 years. We enrolled eighty-two biopsy and/or angiographically proven PCNSV cases. The median age at presentation was 34 years with a male predilection and a median diagnostic delay of 23 months. Most patients presented with seizures (70.7%). All patients had haemorrhages on MRI. Histologically lymphocytic subtype was the commonest. Corticosteroids with cyclophosphamide was the commonest medication used. The median mRS at follow-up of 2 years was 2 (0-3), and 65.2% of patients achieved a good functional outcome. Myelitis and longer duration of illness before diagnosis were associated with poorer outcomes. The presence of hemorrhages on SWI sequence of MRI might be a sensitive imaging marker. Treatment with steroids and another immunosuppressant probably reduced relapse rates in our cohort. We have described the third largest PCNSV cohort and multi-centre randomised controlled trials are required to study the relative efficacy of various immunosuppressants.Study registration: CTRI/2018/03/012721.
