Ageing can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study by Cardiff University.

The discovery gives researchers a new area to focus on in the search for treatments that can protect cognitive function.

Claudia Metzler-Baddeley, from Cardiff University’s Brain Imaging Research Centre (CUBRIC), said: “The brain is made up of grey and white matter. While grey matter contains neuronal cells, which perform computations in our brain, the white matter contains connections and support cells that help the communication between different areas.

“Our new study not only confirms that aging leads to both grey matter decline in the hippocampus and white matter decline in the surrounding area, but also reveals the causal relationship between the two.

“Using a method called mediation analysis, we discovered that ageing of the white matter was accounting for ageing of hippocampal grey matter and not the other way around. Our results suggest that damage to the support cells may affect tissue health in the hippocampus, a region important for memory and involved in Alzheimer’s disease.

“This is an exciting find. If hard-working support cells in the white matter start to misfunction with age, then therapies that protect these support cells may aid in the fight against the damage that ageing can do to our cognitive ability.”

The study, which looked at the brains of 166 healthy volunteers, was carried out using state-of-the-art brain imaging techniques at CUBRIC and was jointly funded by the Alzheimer’s Society and the BRACE Alzheimer’s charity.

The research “Fornix white matter glia damage causes hippocampal gray matter damage during age-dependent limbic decline” is published in Scientific Reports.

CPR can save lives in dialysis clinics, but it’s underused

New research indicates that when kidney failure patients experience cardiac arrest at outpatient dialysis facilities, cardiopulmonary resuscitation (CPR) can save lives, but it is not always performed by dialysis staff. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN), indicate that addition research is needed to...

Scientists discover new mechanism by which sleep supports the immune system

Getting enough sleep is vital to supporting our immune system in fighting off pathogens - so much is common knowledge. But what we don't know is how exactly sleep affects certain immune functions. Scientists at the University of Tübingen and the University of Lübeck have now discovered a new mechanism by which sleep supports the...

Even psychological placebos have an effect — ScienceDaily

Placebo effects do not only occur in medical treatment -- placebos can also work when psychological effects are attributed to them. Psychologists from the University of Basel reported these findings in the journal Scientific Reports, based on three studies with over 400 participants. Psychotherapy and placebos are both psychological interventions that not only have comparable...

Better architectural design could stop suicide among young people

Suicide among younger people is often so spontaneous that it can be prevented if they do not encounter a potentially dangerous place outdoors. Getting the form of the built environment correct is therefore a very important factor in stopping suicide among young people. This is the finding of Charlotta Thodelius, a researcher at Chalmers University...
