Heat shock proteins offer clues to reversing dementia in stressed cells

Posted on May 9, 2022 by Rich Haridy

A specific type of heat shock protein was found to reverse the protein misfolding associated with several neurodegenerative diseases

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.

“Reset button” for cells in the brain hints at new treatments for concussion

Posted on May 3, 2022 by Nick Lavars

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→

Trial finds insulin nasal spray may slow age-related cognitive decline

Posted on May 2, 2022 by Rich Haridy

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→

Study suggests blind people excel at memorizing spoken information

Posted on April 29, 2022 by Ben Coxworth

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→

Study finds seven hours of sleep to be optimal from middle-age onwards

Posted on April 29, 2022 by Nick Lavars

A new study suggests that seven hours of sleep per night is best for brain health in middle and old age

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.

Brain chemical linked to kindness and generosity in old age

Posted on April 28, 2022 by Rich Haridy

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→

New study may explain why apathy is the first symptom of Alzheimer’s

Posted on April 26, 2022 by Rich Haridy

New research hypothesizes degeneration in a brain region called the nucleus accumbens could trigger apathy, the earliest psychiatric sign of Alzheimer's disease

Compelling new research from the Indiana University School of Medicine has homed in on a degenerative mechanism that could explain why symptoms such as apathy are the first signs of Alzheimer’s disease. The findings suggest disrupting this process could slow the progression of Alzheimer’s-related dementia.

Portable MRI can accurately detect most common form of stroke

Posted on April 21, 2022 by Rich Haridy

New research has found the world’s first portable MRI machine can accurately detect ischemic strokes. The machine was cleared for use by the US Food & Drug Administration (FDA) in 2020 and researchers are increasingly demonstrating it to be as effectiv… Continue reading Portable MRI can accurately detect most common form of stroke→
