Transient ischemic attacks, or 'mini strokes', cause more damage than was previously thought, researchers have found.
A study, conducted by Lara Boyd, a neuroscientist with the Brain Research Centre at Vancouver Coastal Health Research Institute and the University of British Columbia, used transcranial magnetic stimulation to look at brain activity in patients who had experienced a mini stroke compared to those who had not.
It was found that the damage caused by a mini stroke can last up to two weeks following the event, with the affected side of the brain electrically suppressed and hard to activate.
Experiencing a mini stroke involves symptoms such as sudden severe headaches, weakness, numbness or changes in vision. Having one of these also puts people at a higher risk of experiencing a major one.
This comes after the Manchester Evening News reported that Daniel Adams, 36, is holding his first exhibition after using painting to help him recover from a stroke.
