Memory Problems in Older Patients Not Linked to Surgery
At the start of the study, 361 people had mild to moderate dementia, and 214 were dementia-free.
Those patients were divided into three groups: those who had surgery, those with illness, and a third group with neither.
"We were able to use patients as their own controls before and after surgery and to compare groups of patients over time, and we did not detect any evidence of a long-term cognitive decline. Our findings suggest that if older people physically recover from surgery, they should expect that within six months or a year, they will return to their previous level of cognitive ability, too," said Evers.
Knowing how people functioned for years before and after surgery or illness allowed them to learn whether a major event somehow changed their cognitive trajectories. But it did not, even in patients with dementia at the time of surgery.
"This is an important finding for persons with Alzheimer's and their families who may worry that a pending operation could adversely affect the patient's cognitive status. There has been a widespread belief that the memory and thinking abilities of patients with early Alzheimer's disease may worsen as a consequence of surgery, but the evidence from this study does not support that belief," said Dr. John C. Morris.
The study has been published in the November issue of the journal Anesthesiology.
