There are issues that direct exposure to general anesthesia during surgical treatment might contribute to an increased threat of Alzheimer’s illness. To examine, scientists compared exposure to basic anesthesia versus regional anesthesia during optional surgical treatment, looking for potential links to the development of dementia.
The Journal of the American Geriatrics Society study consisted of 7,499 matched sets of community-dwelling individuals aged 66 years or older who went through surgical treatment in between 2007 and 2011 and were followed for up to 5 years.
The investigators discovered no difference in risk of being identified with dementia for individuals who received general anesthesia when compared with those who received regional anesthesia.
“Many older adults experience changes in their cognition immediately following surgery and wonder what role the type of anesthetic might have played in these changes,” said senior author Dallas P. Seitz, MD, PhD, FRCPC, of the University of Calgary, in Canada. “Our study provides evidence that anesthetic technique used during elective surgeries, general anesthesia or regional anesthesia is not associated with a long-term risk of developing dementia.”
