Teacher: Now, understand the problem? Solve this instance: Question: Does older age limit postbariatric surgery cognitive benefits : a preliminary investigation?
Answer: The present study provides preliminary evidence suggesting that older age does not preclude postbariatric surgery cognitive benefits. Prospective studies in more age diverse samples (i.e., up to 70 yr) are needed to determine whether bariatric surgery can reduce risk of age-related neurologic conditions like Alzheimer's disease and stroke.
