Major surgery doubles the risk of substantial mental decline, study finds
Scientists flag strokes, mini-strokes and inflammation among the dangers of going under the knife
Major surgery doubles the chance of a substantial decline in mental skills, including reasoning, memory and language ability, a study suggests.
Doctors and scientists have long feared that general anaesthetic, mini-strokes or inflammation may damage the brain during surgery, but there has been little evidence to demonstrate a long-term impact.
