| Abstract | BACKGROUND: Intravenous tissue-plasminogen activator remains the only U.S. Food and Drug Administration-approved treatment for acute ischemic stroke. Timely administration of fibrinolysis is balanced with the need for accurate diagnosis. Stroke mimics represent a heterogeneous group of patients presenting with acute-onset focal neurological deficits. If these patients arrive within the extended time window for acute stroke treatment, these stroke mimics may erroneously receive fibrinolytics. OBJECTIVE: This review explores the literature and presents strategies for differentiating stroke mimics. DISCUSSION: Clinical outcome in stroke mimics receiving fibrinolytics is overwhelmingly better than their stroke counterparts. However, the risk of symptomatic intracranial hemorrhage remains a real but rare possibility. Certain presenting complaints and epidemiological risk factors may help differentiate strokes from stroke mimics; however, detection of stroke often depends on presence of posterior vs. anterior circulation strokes. Availability of imaging modalities also assists in diagnosing stroke mimics, with magnetic resonance imaging offering the most sensitivity and specificity. CONCLUSION: Stroke mimics remain a heterogeneous entity that is difficult to identify. All studies in the literature report that stroke mimics treated with intravenous fibrinolysis have better clinical outcome than their stroke counterparts. Although symptomatic intracranial hemorrhage remains a real threat, literature searches have identified only two cases of symptomatic intracranial hemorrhage in stroke mimics treated with fibrinolytics. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
