In today's health news:
Marijuana may be a stroke trigger in young adults, New Zealand researchers said yesterday at an international medical conference, suggesting that the drug may not be the "relatively safe" substance many people think it is. CBSNews.com said 16 percent of study participants who went to the hospital after a stroke had pot in their system, compared to 8.1 percent of control subjects.
The number of people with Alzheimer's disease in the U.S. is expected to triple over the next 40 years, says a new study in the journal Neurology, meaning nearly 14 million people are projected to have the disease in 2050. That's compared to 4.7 million in 2010. On a related note, the Food and Drug Administration released a draft of new guidelines for drug companies that are trying to develop treatment for patients in the early stages of Alzheimer's.
Being overweight has been linked to a higher risk of gum disease. New research appearing in General Dentistry says obese people's bodies overproduce a class of protein known as cytokines, which the lead author says "may directly injure the gum tissues or reduce blood flow to the gum tissues," promoting gum disease development.
According to U.S. News & World Report, a new study has linked preschoolers whose parents report depression and domestic violence with a higher risk of developing attention-deficit/hyperactivity disorder (ADHD). Children with depressed mothers, in particular, may be more likely to receive prescription medication to treat mental health issues later in their lives.
Implementing minimum-pricing laws for alcohol would likely lead to a significant drop in alcohol-related deaths, says new research. The BBC said authors of a new study associated a 10 percent rise in alcohol prices to a 32 percent drop in deaths, suggesting to them that there are "immediate, substantial and significant reductions" within reach.
Restaurants considering offering a healthier menu should also consider the findings of new research: Business seems to improve when chains offer more low-calorie options. HealthDay says healthier menus were associated with better sales growth, more customer traffic and bigger gains in total servings.
And finally: New research in Psychological Science says self-reported feelings of well-being tend to increase with age – but a person's overall level of happiness depends on when she or he was born. Older adults had lower levels of well-being than their younger and middle-aged counterparts, which may be attributable to the fact that they started their lives in earlier times, with lower levels of well-being to begin with.
