The Changing face of transient ischaemic attacks

Abstract

ABSTRACT: A transient ischaemic attack (TIA) is a major warning of an impending stroke. The risk of recurrent TIA or stroke is highest during the first 24 hours. 80% of recurrence risk is reduced with early initiation of effective treatment. Many things have changed regarding TIAs over the last decade. The definition of TIA has changed from a time-based to a tissue-based one. Strategies for investigation and treatment have changed, with specialist evaluation and management recommended for all TIAs within 24 hours of symptom onset. Dedicated TIA clinics have revolutionized the approach to TIA management. Improving awareness on early recognition and establishing pathways for rapid delivery of optimal care for TIAs will go a long way in minimizing the burden of stroke in Sri Lanka.
