You'll have to ask your doctor how they will guarantee that you won't have silent strokes. If they don't know why those strokes are occurring ask what research they are working on to find out why and how to prevent them. OR, you could just let them be incompetent and DO NOTHING. Up to you if you want good doctors or not.
Silent Strokes Common After Surgery in Elderly Patients, Linked to Cognitive Decline
Silent
strokes are common in elderly patients after they have elective,
non-cardiac surgery and double their risk of cognitive decline 1 year
later, according to a study published in The Lancet.
While an overt stroke causes obvious symptoms, such as weakness in 1 arm or speech problems that last more than a day, a covert stroke is not obvious except on brain scans.
“We’ve found that ‘silent’ covert strokes are actually more common than overt strokes in people aged 65 or older who have surgery,” said PJ Devereaux, MD, McMaster University, Hamilton, Ontario.
The researchers found that 1 in 14 people aged older than 65 years who had elective, non-cardiac surgery had a silent stroke, suggesting that as many as 3 million people in this age category globally suffer a covert stroke after surgery each year.
The NeuroVISION study involved 1,114 patients aged 65 years and older from 12 centres in North and South America, Asia, New Zealand, and Europe. All patients received an MRI within 9 days of their surgery to look for imaging evidence of silent stroke. The researchers followed the patients for 1 year after their surgery to assess their cognitive capabilities.
Results showed that people who had a silent stroke after surgery were more likely to experience cognitive decline, perioperative delirium, overt stroke or transient ischaemic attack within 1 year compared with patients who did not have a silent stroke.
“Over the last century, surgery has greatly improved the health and the quality of life of patients around the world,” said Marko Mrkobrada, MD, University of Western Ontario, London, Ontario. “Surgeons are now able to operate on older and sicker patients thanks to improvements in surgical and anaesthetic techniques. Despite the benefits of surgery, we also need to understand the risks.”
“The NeuroVISION Study provides important insights into the development of vascular brain injury after surgery, and adds to the mounting evidence of the importance of vascular health on cognitive decline,” said Brian Rowe, Institute of Circulatory and Respiratory Health, Canadian Institutes of Health Research, Ottawa, Ontario. “The results of NeuroVISION are important and represent a meaningful discovery that will facilitate tackling the issue of cognitive decline after surgery.”
