Researchers have identified an accurate ‘signature’ that may signal a person’s risk of dementia five to 10 years before symptoms appear. The biomarker could provide an early diagnosis, allowing therapeutic interventions to slow the disease’s progress.
-
Researchers have created an ultra-thin sensor that can wirelessly record deep brain activity down to a resolution of one or two neurons. The device has potential applications in conditions such as epilepsy, Parkinson’s disease, and chronic pain.
-
Researchers have uncovered a brain mechanism that causes 'the munchies' after cannabis use, paving the way for therapeutics to treat appetite disorders like anorexia and obesity and to improve the appetite of patients undergoing cancer treatment.
-
Researchers have found that exercise releases dopamine, which produces a corresponding reduction in reaction time, and say that exercise could be an effective treatment for conditions such as Parkinson’s disease, where dopamine plays a key role.
-
Scientists have, for the first time, identified five distinct subtypes of Alzheimer’s disease, each with different neurodegenerative behaviors, survival rates and medical interventions. It could be a game-changer for research and therapeutic success.
-
Researchers have created a thin transparent neural implant that can monitor activity on the brain's surface but also account for functions at a deeper level. The hope is that it will lead to an accurate but less invasive brain-computer interface.
-
Slowing down the dreaded aging process interests everybody, and now scientists have uncovered a new pathway to doing so. The team identified a feedback loop in the brain, and found that ramping up its activity helped mice live longer and healthier.
-
A study has found that people with obesity who underwent weight-loss surgery had stable cognition two years after, and their executive function improved. It's a positive finding, given the association between obesity and rapid cognitive decline.
-
A team from Stanford has discovered a way to heighten hypnotic susceptibility. Using targeted neurostimulation the researchers have been able to amplify a person’s response to hypnosis, and the breakthrough could change the way therapy is administered.
-
For the first time, research has shown that a person’s beliefs influence brain activity and connectivity, producing a dose-dependent effect that was only thought to occur with pharmaceutical agents. The findings may improve responsiveness to medications.
-
A study has found that, for older adults living alone, owning a pet was linked to slower rates of decline in some aspects of cognition and may completely offset the association between living alone, a recognized dementia risk, and cognitive decline.
-
A study has found that treatment with a ‘chemical chaperone’ reduced the accumulation of protein plaques and restored cognitive functioning in mouse models of Alzheimer’s, which could lead to novel treatments to help treat the debilitating disease.
