For the first time, scientists have found a connection between abnormalities in how the brain breaks down glucose and the severity of the signature amyloid plaques and tangles in the brain, as well as the onset of eventual outward symptoms of Alzheimer’s disease.
Science is increasingly clear that constant exposure to stress in youth affects their bodies in ways that alters their brains and changes their response systems, especially younger children exposed more challenges, experts told attendees of a Health Journalism 2017 panel in Orlando.
Panelists noted that stress, even in young children, can be good. It helps spark protective reactions to protect the body from harm – say, crossing a busy street. But studies have shown the constant bombardment of stressful situations in kids can have a serious, cumulative impact. Continue reading
Are there different levels of death? Are you alive if you’re brain dead but on life support?
Many journalists and members of the public are unclear about the nuances of brain death. According to this new tip sheet from author and researcher Alan Cassels, this confusion directly affects issues such as organ donation rates.
Cassels notes that while a patient’s organs can be “kept alive” while awaiting transplantation, brain death is legally the same as cardiopulmonary death – death is death. It matters because the organ donor transplant list keeps growing. Continue reading
Conversations about concussions, traumatic brain injury and chronic traumatic encephalopathy (CTE) have become more common in recent years as many military veterans return with disabling head injuries and the impact of football injuries on the brain gets more scrutiny in medical research.
The recent movie “Concussion,” starring Will Smith, raised even more awareness of the sports side of the issue. The higher profile in the media about sports head injuries, specifically in football, was the focus of a well-attended panel, “Covering the Concussion Crisis: Research and Real Life,” at the Health Journalism 2016 conference last month.

More confirmation on the benefits of exercise for older adults.
In a recent study, those who reported doing little to no exercise showed greater long-term decline in memory and thinking skills, compared with those having high activity levels. The difference was equivalent to 10 years of aging, according to researchers at the University of Miami, Florida, and Columbia University, New York. Continue reading
