Obesity linked to abnormal reward response to sugary foods

Posted on Leave a commentPosted in Anatomy, Diabetes, Diet, Epidemiology, Medical News, Mental Health, Nutrition, Obesity

An unhealthy diet is considered a key contributor to obesity. When it comes to cravings for sweet treats, however, impairments in the brain’s reward system might be to blame. Researchers say the reward system in the brains of obese individuals appears to be impaired in response to sweet foods. In a new study published in […]

New Imaging Technique May Find Real Alzheimer’s Culprit

Posted on Leave a commentPosted in Aging/Growth, Biomedical Science, Medical News, Mental Health, Neurology

Scientists are peeking inside living brains to watch for the first time as a toxic duo of plaques and tangles interact to drive Alzheimer’s disease — and those tangles may predict early symptoms, a finding with implications for better treatments. It’s not clear exactly what causes Alzheimer’s. Its best-known hallmark is the sticky amyloid that […]

Does acetaminophen/paracetamol reduce empathy?

Posted on 3 CommentsPosted in Biomedical Science, Epidemiology, Medical News, Mental Health, Neurology, Pain, Pharmaceuticals

Researchers from The Ohio State University have found evidence that acetaminophen not only dulls physical pain, it also reduces our ability to predict pain in others and empathize. If the results are to be believed, this common drug might hamper our ability to imagine each other’s discomfort. Used to relieve pain and fever, acetaminophen – […]
