A University of Manchester study of over 400 people in eight EU countries with severe dementia has found that those residing in long-term care homes are less likely to suffer from depressive symptoms than those living in the community.
Researchers studied 414 people with severe dementia along with their carers in England, Estonia, Finland, France, Germany, the Netherlands, Spain and Sweden. The study gathered information on quality of life, activities of daily living such as bathing, feeding and dressing and presence of depressive symptoms using standardised measures.
In the groups studied, 37% of the 217 people living in the community showed signs of depression compared to 23% of the 197 in care homes. It is one of the few studies comparing similar groups of people living at home and in nursing homes.

The smart phone has changed our behavior, sometimes for the better as we are now able to connect and engage with many more people than ever before, sometimes for the worse in that we may have become over-reliant on the connectivity with the outside world that these devices afford us. Either way, there is no going back for the majority of users who can almost instantaneously connect with hundreds if not thousands of people through the various social media and other applications available on such devices and not least through the humble phone call.
However, our dependence brings anxiety. The loss of one’s smart phone not only represents an immediate disconnection from one’s online contacts but is also a potential privacy and security risk should the lost phone wend its way into the hands of a malicious third party. Writing in the International Journal of Mobile Communications, a Canadian team outlines the possible coping mechanisms that might be needed following loss or theft and the security problems that the user might face. The researchers point out that the same anxieties apply equally to lost or stolen laptops, tablet computers and other digital devices.
Using marijuana at least once a week can lead to cognitive decline, poor attention and memory and decreased IQ in teens and young adults, according to researchers at the American Psychological Association annual meeting.
Krista Lisdahl, Director of the Brain Imaging and Neuropsychology Lab at the University of Wisconsin-Milwaukee, noted that 6.5 percent of high school seniors reported smoking marijuana daily, up from 2.4 percent in 1993. Among young adults ages 18 to 25, almost one-third said they had used marijuana in the last month, Lisdahl noted in a new release. She said a 2012 study found people who have become addicted to marijuana can lose an average of six IQ points by adulthood.

A new study of thousands of Americans finds people with a history of drinking problems have more than twice the risk of memory problems later in life, compared with those who have never been heavy drinkers.
The researchers asked participants four questions: Have you ever felt you should cut down on your drinking? Have people ever annoyed you by criticizing your drinking? Have you ever felt guilty about drinking? And have you ever had a drink first thing in the morning? These questions come from a widely used screening questionnaire for alcoholism, The Wall Street Journal reports.
Participants were born between 1931 and 1941. They answered the questions about alcohol use when they were first interviewed, when they were in their 50s and 60s. They were considered to have a drinking problem if they answered yes to at least two of the four questions. They had follow-up memory tests every other year from 1996 to 2010, the article notes.

The National Institute on Drug Abuse (NIDA) is releasing new resources to help parents, health care providers and substance abuse treatment specialists treat teens who are struggling with drug abuse. The resources also provide advice on identifying and interacting with teens who may be at risk.
