A fitness tracker for brain health: How a headband can identify early signs of Alzheimer’s disease in your sleep

Researchers make progress in developing a digital biomarker that detects early signs of Alzheimer’s disease in brainwave patterns using a simple ‘wearable’ headband at night.

How artificial intelligence gave a paralyzed woman her voice back

Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.

Study adds to evidence that Parkinson’s starts in the gut

Many researchers believe that the neurodegenerative disorder gets started in the gut. Research now suggests that an autoimmune reaction may be driving those early events.

PS gene-editing shown to restore neural connections lost in brain disorder

A new study has demonstrated the ability for gene therapy to repair neural connections for those with the rare genetic brain disorder known as Hurler syndrome.

Overuse of social media and devices top parent concerns as kids head back to school

As children head back to school, two issues have climbed higher on their parents’ list of concerns: the role of social media and the internet in kids’ lives.

Formerly depressed patients continue to focus on negative

People who have recovered from a major depressive episode, when compared with individuals who have never experienced one, tend to spend more time processing negative information and less time processing positive information, putting them at risk for a …

New insights into the protein-mediated motor neuron loss in amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a widespread neurodegenerative disease caused by the loss of neurons that control movement. Although abnormal accumulation of proteins called TDP-43 accompanies ALS, its role in disease progression is not well und…

Platelets can replicate the benefits of exercise in the brain

Researchers have found an injection of a specific blood factor can replicate the benefits of exercise in the brain. They’ve discovered that platelets secrete a protein, exerkine CXCL4/Platelet factor 4 or PF4, that rejuvenates neurons in aged mice in a…

Anxious people use less suitable section of brain to control emotions

When choosing their behavior in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious.

Lesser-known brain cells may be key to staying awake without cost to cognition, health

New animal research suggests that little-studied brain cells known as astrocytes are major players in controlling sleep need and may someday help humans go without sleep for longer without negative consequences such as mental fatigue and impaired physi…
