Doctors are writing lots of prescriptions for drugs to calm the behavior of people with Alzheimer's disease and other types of dementia, but non-drug approaches work better and carry far fewer risks, according to a new paper.  

In contrast to current protocol non-drug approaches should be the first choice for treating dementia patients' common symptoms such as irritability, agitation, depression, anxiety, sleep problems, aggression, apathy and delusions, write a team in British Medical Journal after reviewing two decades' worth of research on antipsychotics, antidepressants and non-drug approaches that help caregivers address behavioral issues in dementia patients. 

Researchers have identified distinct immune changes in patients diagnosed with chronic fatigue syndrome, known medically as myalgic encephalomyelitis (ME/CFS) or systemic exertion intolerance disease.

This is
the first robust physical evidence that ME/CFS is a biological illness as opposed to a psychological disorder, and the first evidence that the disease has distinct stages and could help improve diagnosis and identify treatment options for the disabling disorder, in which symptoms range from extreme fatigue and difficulty concentrating to headaches and muscle pain.

How will we know if the economy has really gotten better, rather than using bogus claims about employment or how well Wall Street executives are doing? When senior citizens stop killing themselves.

Suicide rates for adults between 40 and 64 years of age in the U.S. rose about 40% since 1999, with a sharp rise after in 2007 that continued during the economic downturn of 2008 and on, which led to disproportionate effects on house values, household finances, and retirement savings for that age group. In a study published in the American Journal of Preventive Medicine, researchers found that external economic factors were present in 37.5% of all completed suicides in 2010, rising from 32.9% in 2005.

Enzymes are the workhorses of our bodies, they make biochemical reactions happen faster than they otherwise would and sometimes essential reactions would not happen at all without them. 

The Rubisco enzyme, the most abundant protein on the planet, has one of the most significant responsibilities in life on Earth - the conversion of carbon dioxide to organic compounds, the building blocks of all plant and animal cells.

People with diabetes are prone to anxiety and depression but others with chronic diseases that require similar levels of management suffer from anxiety and depression less.

Why that might be is unclear but Joslin Diabetes Center researchers have offered an explanation, gleaned by genetically modifying mice to make their brains resistant to insulin. They found that the animals exhibited behaviors that suggest anxiety and depression, and then pinpointed a mechanism that lowers levels of the key neurotransmitter dopamine in areas of the brain associated with those conditions.

Want to lower your risk of dying from a heart attack? Go a little nuts.

Peanuts are getting a modern rehabilitation.  Except for severe cases, it has been found that peanut allergies will go away if kids eat them early, and when they reach adulthood they will have less likelihood of dying from heart disease - and be an equalizer across low-income and racially diverse populations.
