According to the new researches, patients who undergo anesthesia and surgery may have a higher risk of dementia. This is ture in many former cases and trials. In fact, surgery at old age can also carry more severe, and less common, health risks. Also, simply surviving surgery can be difficult for elderly patients, especially those over the age of 80. Because they are much more vulnerable to many diseases and infections. So at present, we still cannot understand the real cause behind such a higher risk. Actually, further research is essential to find why they have these effects and how to do surgery with the least risk. However, if surgery is necessary, patients should not fear the risks. All what they need to do is keep in close contact with the doctor and work together for a best treatment plan. Keywords: dementia after surgery
