Distinction between preclinical Alzheimer's disease and depression

Article Abstract:

Distinguishing between depression and preclinical Alzheimer's disease (AD) is discussed relative to a prospective observational cohort study at an outpatient memory clinic of a university-affiliated hospital. Depression was found to be common in preclinical AD patients. Those with preclinical AD can be differentiated from those with depression-related cognitive impairment by severity of memory loss and age. Preclinical AD is often accompanied by depression and research investigating preclinical AD should not exclude those with depression a priori

An operation under general anesthesia as a risk factor for age-related cognitive decline: results from a large cross-sectional population study

Article Abstract:

Research shows no correlation between the use of general anesthesia and cognitive impairment. In studies of elderly surgical patients, no evidence was found that anesthesia brought on or accelerated age-related cognitive decline. While anesthesia usage increased the number of patients' health-related complaints, memory complaints were not statistically significant.
