The inherent difficulties in properly diagnosing concussion have scientists searching far and wide for biomarkers that clearly reveal the extent of a brain injury. For scientists at the Houston Methodist Research Institute, this search has led them to … Continue reading Study links concussion to changes in gut bacteria
An ongoing study is testing a new kind of neuroimaging device designed to easily capture brain activity in real-time. These preliminary experiments will investigate the effects of ketamine on functional connectivity in the brain before, during and afte… Continue reading Brain imaging helmet tracks psychedelic experiences in ketamine study
Researchers investigating the effects of stress on accumulations of toxic brain proteins linked with dementia have discovered a surprisingly counter-intuitive mechanism. A specific cellular stress response involving heat shock proteins has been found to reverse the build-up of these toxic proteins and future research will now look for a way to therapeutically trigger this mechanism.

Researchers have homed in on several strains of gut bacteria that are associated with the severity of a common form of stroke. The findings build on a growing body of research suggesting future therapies targeting the gut microbiome could reduce a pers… Continue reading Stroke severity linked to certain strains of gut bacteria
A new study has presented the most rigorous investigation to date into the long-term cognitive impacts of severe COVID-19. The research, led by scientists from Imperial College London and the University of Cambridge, found persistent cognitive deficits… Continue reading Cognitive impact of severe COVID equal to 20 years of brain aging
The way the brain responds to traumatic injuries is a matter of intense interest to medical scientists investigating concussion and its significant health impacts. Through experiments on mice in which a key set of immune cells were essentially reset af… Continue reading “Reset button” for cells in the brain hints at new treatments for concussion
The results of a small Phase 2 clinical trial offers promising signs that daily doses of an insulin nasal spray could be used to slow age-related cognitive decline. The trial found the treatment to be effective in elderly subjects both with and without… Continue reading Trial finds insulin nasal spray may slow age-related cognitive decline
There’s a longstanding belief that when someone loses one ability, another improves correspondingly. New research bears this out – in one scenario, at least – as it indicates that blind people remember spoken information better than their sighted count… Continue reading Study suggests blind people excel at memorizing spoken information
We know sleep to be an essential ingredient for a healthy brain, but scientists continue to explore what a good night’s rest looks like at different stages of life, and how it can impact on our vulnerability to cognitive decline. A wide-ranging new study involving almost half a million subjects has provided compelling new insights, suggesting seven hours of sleep per night to be best for brain health during middle and old age.

A fascinating new study has suggested a link between increased generosity in older age and levels of a neurochemical called oxytocin. The research found older people with higher levels of oxytocin were more likely to donate money to charity and be sati… Continue reading Brain chemical linked to kindness and generosity in old age
