Early exposure to antidepressants affects adult anxiety, serotonin transmission


December 19th, 2014         by Latest Science News -- ScienceDaily

Early developmental exposure to two different antidepressants, Prozac and Lexapro, has been studied by researchers in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice. About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants. Continue reading ...

Technophobia may keep seniors from using apps to manage diabetes


December 19th, 2014         by Latest Science News -- ScienceDaily

Despite showing interest in web or mobile apps to help manage their type 2 diabetes, only a small number of older adults actually use them, says a new study. Approximately 2.2 million Canadians are living with type 2 diabetes, 2 million of whom are age 50 or older. A study found that although more than 90 per cent of research participants owned a computer or had daily Internet access, just 18 per cent used applications on this technology to help manage their diabetes. While almost half owned smartphones, only 5 per cent used them to manage their disease. Continue reading ...
