Abstract OBJECTIVE: To determine the prevalence of diffusion-weighted imaging (DWI)-negative acute ischemic stroke (AIS) and to identify clinical characteristics of patients with DWI-negative AIS. METHODS: We systematically searched PubMed and Ovid/MEDLINE for relevant studies between 1992, the year that the DWI sequence entered clinical… Read More How often is the MRI normal following ischaemic stroke?
Mechanical thrombectomy outcomes with and without intravenous thrombolysis in stroke patients: a meta-analysis. Mistry EA, Mistry AM, Nakawah MO, et al. Stroke 2017; 48:2450-2456. Abstract Background: Whether prior intravenous thrombolysis provides any additional benefits to the patients undergoing mechanical thrombectomy for large vessel, acute ischemic stroke remains unclear. Methods: We conducted a meta-analysis of 13 studies obtained through PubMed and EMBASE database searches to determine whether functional… Read More Does thrombolysis add any value to mechanical thrombectomy after stroke?
Sugar and artificially sweetened beverages and the risks of incident stroke and dementia: a prospective cohort study. Pase MP, Himali JJ, Beiser AS, et al. Stroke 2017; 48:1139-1146. Abstract Background: Sugar- and artificially-sweetened beverage intake have been linked to cardiometabolic risk factors, which increase the risk of cerebrovascular disease and dementia. We examined whether sugar-… Read More Do artificial sweeteners increase the risk of stroke and dementia?
Intravenous thrombolysis in unknown-onset stroke: results from the safe implementation of treatment in Stroke-International Stroke Thrombolysis Registry. Dorado L, Ahmed N, Thomalla G, et al. Stroke 2017; 48:720-725. Abstract Background: Stroke patients with unknown onset (UKO) are excluded from thrombolytic therapy.

Abstract OBJECTIVE: In a cohort of patients diagnosed with cervical artery dissection (CeAD), to determine the proportion of patients aged ≥60 years and compare the frequency of characteristics (presenting… Read More Why is the diagnosis of cervical artery dissection difficult in older people?
Thrombectomy for ischemic stroke: meta-analyses of recurrent strokes, vasospasms, and subarachnoid hemorrhages. Emprechtinger R, Piso B, Ringleb PA. J Neurol 2017; 264:432-436. Abstract Background: Mechanical thrombectomy with stent retrievers is an effective treatment for patients with ischemic stroke. Results of recent meta-analyses report that the treatment is safe. However, the endpoints recurrent stroke, vasospasms, and… Read More What are the downsides of mechanical thrombectomy for stroke?
