OBJECTIVES Transient ischaemic attacks (TIAs) are an important precursor of stroke. Atrial fibrillation (AF) is among the most dangerous aetiologies shared between TIAs and strokes. Detection of AF after TIAs is essential for the initiation of oral anticoagulants. We aimed to identify variations in the use of cardiac investigations used to detect AF and cardiac pathology in patients with TIA in...

BACKGROUND A Transient Ischaemic Attack (TIA) bears a high risk of a subsequent ischaemic stroke. Adequate diagnosis of a TIA should be followed immediately by the start of appropriate preventive therapy, including antiplatelets. The diagnosis of a TIA based on symptoms and signs only is notoriously difficult and biomarkers of brain ischaemia might improve the recognition, and target management...

BACKGROUND Point-of-care (POC) diagnostic tests with good sensitivity and specificity are needed for diagnosing failure of transfer of passive immunity (FTPI) in foals. Turbidimetric immunoassays (TIA) have these characteristics and provide quantitative results. A commercially available TIA-based POC test (POC-TIA) has not been validated in horses. OBJECTIVE To validate a POC-TIA and compare ...

BACKGROUND The ABCD2 score predicts stroke risk within a few days of transient ischaemic attack (TIA). It is not clear whether the predictive value of the ABCD2 score can be generalised to UK TIA services, where delayed presentation of TIA and minor stroke are common. We investigated prognosis, and the use of the ABCD2 score, in patients attending TIA services in the North West of England with ...

BACKGROUND Little is known about short-term vascular risk after transient ischemic attack (TIA) caused by intracranial atherosclerosis. OBJECTIVES To quantify the early risk of ischemic stroke in the territory of a stenotic intracranial artery after TIA and to identify clinical and imaging features associated with increased risk of stroke in the territory among patients with TIA. DESIGN Coh...

BACKGROUND AND PURPOSE Diffusion MRI has established value in patients with ischemic stroke but has not been systematically investigated in patients with transient ischemic attack (TIA). METHODS Clinical, conventional MRI, and diffusion MRI data were collected on 42 consecutive patients with symptoms of cerebral TIA. TIA imaging data were compared with those from a contemporaneous group of 23...

BACKGROUND AND PURPOSE Stroke risk after transient ischemic attack (TIA) has not been examined in an ethnically diverse population-based community setting. The purpose of this study was to identify stroke risk among TIA patients in a population-based cerebrovascular disease surveillance project. METHODS The Brain Attack Surveillance in Corpus Christi (BASIC) Project prospectively ascertains s...

The yearly incidence of TIA in the United States has been estimated to be approximately 200,000 to 500,000 but may be higher because of the high frequency of underreporting of these events by medical professionals. The annual incidence of TIA may be less and the annual incidence of stroke may be higher if the tissue-based definition were applied to all patients evaluated for TIA. It has been es...

BACKGROUND Transient ischaemic attack (TIA) is characterised by its transient nature with symptoms of neurological dysfunction resolving within 24 hours. The occurrence of TIA is a major risk factor for stroke with 10-15% of TIA patients going on to have ischaemic stroke. Internationally, recommendations for the management of TIA focus on the need for early diagnosis and medical management of t...
