Daytime napping is common among older adults. New research from the Johns Hopkins Bloomberg School of Public Health suggests that how often, how intentionally, and how long older people nap may be linked to their risk of developing dementia.

Alcohol withdrawal is a very common and dangerous medical emergency. Although benzodiazepines remain the standard treatment for this condition, the use of the barbiturate phenobarbital has increased by more than 200% in the last decade with limited evidence to suggest that this practice is safe and effective.

In the first large-scale study to compare phenobarbital to diazepam—a long-acting benzodiazepine -– researchers found no differences in outcomes between phenobarbital and diazepam, potentially suggesting similar effectiveness.
