Transient ischemic attacks (TIAs), like other vascular diseases, whether acute limb ischemia or acute coronary syndromes, are high-risk, unstable conditions. TIA heralds a relatively high risk of stroke, variably estimated to range between 10% and 20% in the ensuing 90 days.1–4 This has been known for several decades.5–8 What is new are reports that show that at least half of the risk of early ...

OBJECTIVE To compare outcomes at 28 days and 1 year between patients admitted to hospital and those discharged after presenting to the emergency department (ED) with transient ischaemic attack (TIA). DESIGN AND SETTING All TIA presentations to EDs in a large metropolitan and rural region of Sydney and its surroundings, New South Wales, between 2001 and 2005 were extracted from state health de...

OBJECTIVES To measure the number of all transient ischaemic attack (TIAs) and minor strokes managed as outpatients, and hence, the need for 'TIA clinics' in comparison to current estimates of 20,000 TIAs annually in England, based on previous rates of incident-definite events. SUBJECTS All individuals with confirmed or suspected TIA or stroke between 2002 and 2005 in a population-based study ...

BACKGROUND Previous literatures have shown a transient ischemic attack (TIA) mimic rate of 9-31%. We aimed to ascertain the proportion of stroke mimics amongst suspected TIA patients. METHODS A prospective observational study was performed in Ghaem Hospital, Mashhad, Iran during 2012-2013. Consecutive TIA patients were identified in a stroke center. The initial diagnosis of TIA was made by th...

BACKGROUND AND PURPOSE The evidence that obstructive sleep apnea/hypopnea (OSAH) is a risk factor for ischemic cerebrovascular disease is inconclusive. We explored this relationship in transient ischemic attack (TIA) patients because they are less likely than stroke patients to have OSAH as a consequence of cerebrovascular disease. METHODS We performed a case-control study among 86 patients w...

BACKGROUND To evaluate the performance of a novel triage system for Transient Ischemic Attack (TIA) units built upon an existent clinical prediction rule (CPR) to reduce time to unit arrival, relative to the time of symptom onset, for true TIA and minor stroke patients. Differentiating between true and false TIA/minor stroke cases (mimics) is necessary for effective triage as medical interventi...

BACKGROUND AND PURPOSE Patterns of DWI findings that predict recurrent ischemic events after TIA are well-established, but similar assessments of intracranial MRA findings are not available. We sought to determine the imaging characteristics of MRA that are predictive of early recurrent stroke/TIA in patients with TIA. MATERIALS AND METHODS We performed a retrospective analysis of 129 consecu...

BACKGROUND AND PURPOSE Posttraumatic stress disorder (PTSD) is common in survivors of acute life-threatening illness, but little is known about the burden of PTSD in survivors of stroke and transient ischemic attack (TIA). This study estimated the prevalence of stroke or TIA-induced posttraumatic stress disorder (PTSD) using systematic review and meta-analysis. METHODS Potentially relevant pe...

BACKGROUND Transient ischemic attack (TIA) is usually defined as a neurologic ischemic disorder without permanent cerebral infarction. Studies have showed that patients with TIA can have lasting cognitive functional impairment. Inherent brain activity in the resting state is spatially organized in a set of specific coherent patterns named resting state networks (RSNs), which epitomize the funct...
