Associate Professor Thomas Burne at UQ’s Queensland Brain Institute led the studies, which provide the groundwork for research into better prevention and treatments.
“Over a billion people worldwide are affected by vitamin D deficiency, and there is a well-established link between vitamin D deficiency and impaired cognition,” Dr Burne said.
“Unfortunately, exactly how vitamin D influences brain structure and function is not well understood, so it has remained unclear why deficiency causes problems.”
Dr Burne’s team found that vitamin D levels affect a type of ‘scaffolding’ in the brain, called perineuronal nets.
“These nets form a strong, supportive mesh around certain neurons, and in doing so they stabilise the contacts these cells make with other neurons,” he said.
