A large study has linked abnormal heart rhythm to cognitive decline, the latest evidence that connects common cardiovascular conditions with dementia. But there is some good news: Early diagnosis and medication may completely remove the increased risk.
-
Researchers used repetitive magnetic stimulation on the brain of a man who’d had a stroke 12 years ago, improving his walking speed, balance, and coordination. The innovative treatment offers hope to others affected by stroke, even years after.
-
For the first time, scientists have identified how the region of our brain that powers memory is made up of two very different sets of neurons: one that deals with previous associations, and one that is predictive, actively shaping future behaviors.
-
Researchers have converted brain immune cells into neurons, replacing damaged ones and restoring function to stroke-affected mice. If the same results can be achieved in human cells, it opens the door to a potential treatment for stroke.
-
Using a new kind of neuroimaging tool, researchers have uncovered evidence to help explain how antidepressant medications work, and why they take so many weeks to kick in.
-
Researchers have scanned the brains of adolescents with OCD while they performed decision-making tasks and identified the specific areas affected by the condition. It opens the door to more targeted treatment for the condition.
-
When a person has suffered a stroke, the severity of that stroke has to be determined as fast as possible. A new brain-wave-reading cap was created with that fact in mind, as it allows strokes to be assessed before the patient reaches the hospital.
-
Another large study has found a correlation between proton pump inhibitors (PPI) and an increased risk of dementia, particularly for those aged 60-69 years. But frustratingly, scientists still don’t understand exactly what that connection is.
-
New research has for the first time shown how inflammation in early childhood can affect brain development, triggering epigenetic changes in brain regions linked to higher cognitive functions, and play a role in a variety of neuropsychiatric disorders.
-
Desynchronizing the circadian rhythm in rats had a significant impact on appetite and feeding behavior, a study has found. The findings have important implications for night shift workers and those suffering jet lag and chronic sleep disturbances.
-
Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer, and has the potential to provide individualized repairs to brain injuries.
-
Ongoing stress can take a sizeable toll on the body, including higher risks of obesity, graying hair, hypertension, diabetes and cardiovascular disease. And it may be just as damaging to the brain, even doubling the risk of developing dementia.
