The New York Times has described Thomas Eric Duncan, the first person to die of Ebola virus infection in the United States, as “the Liberian man at the center of a widening health scare.” Use of the term “health scare” about Ebola in the U.S. just isn’t warranted, according to a consensus of several Harvard experts who have looked at Ebola through different lenses. They give four main reasons why an epidemic of Ebola virus disease isn’t likely to happen here: 1) the virus is relatively difficult to spread; 2) we have an effective emergency-response infrastructure; 3) Most hospitals are equipped to treat Ebola safely; and 4) new treatments are in the works.

Drugs in the benzodiazepine family have long been used to treat anxiety and sleep problems. They can cause a bit of a brain hangover the next day. Experts have long assumed that people’s heads would clear once they stopped taking the drug. That may not be the case. In a study published last night by the journal BMJ, a team of researchers from France and Canada linked benzodiazepine use to an increased risk of being diagnosed with Alzheimer’s disease. In the study, the greater a person’s cumulative dose of benzodiazepines, the higher his or her risk of Alzheimer’s. Taking a benzodiazepine for less than three months had no effect on Alzheimer’s risk. Taking the drug for three to six months raised the risk of developing Alzheimer’s by 32%, and taking it for more than six months boosted the risk by 84%. People taking a long-acting benzodiazepine were at greater risk than those on a short-acting one.
A new report in JAMA Neurology offers yet another reminder why keeping your blood pressure in the healthy range for as long as you can is a good life strategy. Researchers with the long-term Atherosclerosis Risk in Communities (ARIC) Neurocognitive Study found that memory and thinking skills declined significantly more over the course of a 20-year study in middle-aged people with high blood pressure than it did in those with healthy blood pressure. Interestingly, those who had normal blood pressure in midlife but who developed high blood pressure in their late 60s, 70s, and 80s didn’t have similar declines as those who developed high blood pressure earlier. The main take-home lesson from this study? The longer you live with normal blood pressure, the less likely you are to have memory and reasoning problems when you’re older.
