Thousands of people are putting their lives at risk by dismissing the symptoms of mini-strokes - also known as transient ischaemic attacks or TIAs - as "a funny turn", according to a study by a leading stroke charity.
In a new report the Stroke Association says that if all TIAs were treated quickly, around 10,000 strokes could be prevented every year in the UK - and more than 3,000 lives could be saved.
Nichola Farrelly was in her early 30s when she suffered a mini-stroke in 2012.
She told BBC News how she knew something was wrong.
