I know this is not a comparative physiology topic, but this article caught my attention as I know I just ate a rather high fat meal last week for Thanksgiving and I plan to do the same throughout the holiday season. Insulin does more than just lowering blood sugar by increasing its uptake into tissues. It can also increase blood flow to the hippocampal region of the brain to help cognitive function. This area of the brain is important in memory formation and spatial orientation. A new study published in the American Journal of Physiology - Endocrinology and Metabolism used ultrasound to…

Not all mental decline in the elderly is "normal" and certainly it is not always Alzheimer's: But according to the National Institute on Aging, missed diagnoses of reversible dementia still occur too often. "Some physical and mental changes occur with age in healthy people," the agency writes in a publication called "Forgetfulness." "However, much pain and…
