The effect of surgery and anesthesia on memory and cognition was analyzed in a recent study.
In the study of 312 participants who had surgery and 652 participants who had not (with an average age in the 50s), surgery between tests was associated with a decline in immediate memory by one point out of a possible maximum test score of 30 points. Memory became abnormal in 77 out of 670 participants with initially normal memory comprising 18% of those who had had surgery compared with 10% of those who had not. No differences in other measures of memory and executive function were observed between participants having and not having surgery. Reduced immediate memory scores at the second visit were significantly associated with the number of operations in the preceding nine years.
Dental Anesthesia
The advent of anesthesia may be regarded as a cornerstone in the development of modern dentistry.
"The cognitive changes we report are highly statistically significant in view of the internal normative standards we employ, and the large sample size of the control, or non-surgery, population. But the cognitive changes after surgery are small--most probably asymptomatic and beneath a person's awareness," said senior author Dr. Kirk Hogan, of the University of Wisconsin-Madison School of Medicine and Public Health. "The results await confirmation both in follow-up investigations in our own population sample after more surgeries in aging participants, and by other investigators with other population samples."
