Medical News Today: Boosting the brain’s immune cells may stop Alzheimer’s

The results of two new studies — both published in the journal Neuron — suggest that the brain’s immune cells may hold the key to future treatments for Alzheimer’s disease. Alzheimer’s disease affects more than 5 million people in the United States, and the condition ranks as the 6th leading cause of death in the […]

Medical Xpress: Study backs up connection between atrial fibrillation and dementia

One of the longest and most comprehensive studies to date has found more evidence that people diagnosed with a type of rapid or irregular heartbeat called atrial fibrillation may be at greater risk for cognitive decline and dementia. The new study can’t say whether the association is more than a correlation, and there is no […]

Science Daily: Genes for age-linked brain deterioration identified

A group of genes and genetic switches involved in age-related brain deterioration have been identified. The research found that changes to one of these genes, called Dbx2, could prematurely age brain stem cells, causing them to grow more slowly. (March 5, 2018) Read the full article here

Psychology Today: What happens in the brain during unconsciousness?

The first public demonstration of surgery under anesthesia occurred in 1846. By 1847 people were already theorizing about what might be going on in the brain while a person was unconscious. More than 170 years later, we’re still wondering. Mysteries remain about all forms of unconsciousness—sleep, sedation, deep anesthesia and comas. (March 6, 2018) Read […]

News-Medical: Treatments targeted to enhance brain neurotrophic factor signaling may improve memory functions

Treatments targeted to enhance brain neurotrophic factor signaling could improve memory functions in Alzheimer’s disease even though they don’t alter brain amyloid burden, according to recent research from the University of Eastern Finland. The enhancement of brain derived neurotrophic factor (BDNF) signaling alleviated memory impairment in Alzheimer’s mouse models. (March 6, 2018) Read the full […]

MIT News: Study reveals how the brain tracks objects in motion

Catching a bouncing ball or hitting a ball with a racket requires estimating when the ball will arrive. Neuroscientists have long thought that the brain does this by calculating the speed of the moving object. However, a new study from MIT shows that the brain’s approach is more complex. (March 5, 2018) Read the full […]

UPI: Study: High cholesterol linked to better brain health after age 85

In a seemingly counterintuitive finding, new research suggests that high cholesterol is associated with a reduced risk of mental decline in the elderly. People aged 85 to 94 with good brain function whose cholesterol was above normal had a 32 percent lower risk for mental decline over the next 10 years compared with people aged […]

Medical News Today: Head injuries may lead to early Alzheimer’s

Contact sports that can result in concussions, such as football, have given rise to worries that these head injuries may harm brain health later in life. A new study now investigates these claims in relation to the development of Alzheimer’s disease. (March 6, 2018) Read the full article here

Science Daily: Culprit in Parkinson’s brain cell die-off

An estimated 10 million people worldwide are living with Parkinson’s disease — an incurable neurodegenerative disorder that leads to an increasing loss of motor control. If we could peer into the brains of these patients, we’d see two hallmarks of the disease. First, we’d see a die-off of the brain cells that produce a chemical […]

Reuters: Horseback riding may relieve combat vets’ PTSD symptoms

Therapeutic horseback riding may ease symptoms of post-traumatic stress disorder in combat veterans, a new study finds. After three weekly riding sessions, 32 participating veterans lowered their scores for symptoms of the disorder, known as PTSD, researchers report in Military Medical Research.
