A mini stroke is also called a Transient Ischaemic Attack or TIA. It is a brief episode of dysfunction in the brain. Like a stroke, TIA’s onset is sudden, over a few seconds or minutes.
People having a mini stroke can experience a variety of symptoms. The most important are weakness on one side affecting the face, arm or leg – or all three – or speech disturbance, which can be slurring or decreased speech fluency or comprehension. These are the typical symptoms, but sometimes people can experience visual loss, dizziness or vertigo.
