Funding boost helps NZ researchers

Funding boost helps New Zealand researchers protect our minds and memories

Keeping our brains sharp and memories alive is the focus of at least two research projects that have just received a significant funding boost from the Health Research Council of New Zealand (HRC).

As part of its annual funding round, the government body has just awarded $55.56 million to 49 projects with the potential to vastly improve the health of New Zealanders.

Among the projects is a one-of-a-kind study to identify the earliest signs of dementia, long before clinical diagnosis.

“Imagine you have been diagnosed with dementia. You’re told that it will progressively and irreversibly deprive you of your ability to think, your personality, and your independence,” says lead investigator Associate Professor Maurice Curtis from the University of Auckland.

“Now imagine your doctor tells you that you could have been treated if you were diagnosed 10 years earlier, but the damage to your brain now is too extensive. This is the problem we are trying to solve.”

Remarkably, the driving force behind this study is a large New Zealand family whose members carry a genetic mutation that is known to cause frontotemporal dementia. With 25 members of the family recruited into the study, it’s the world’s largest multi-generational study into this type of dementia.

By assessing blood tests taken annually and measuring ongoing changes in thinking and sense of smell, this longitudinal study aims to compare changes that occur between members of the family who carry the gene and those who don’t.

“This will allow us to measure potential markers of dementia up to 30 years before expected clinical onset, which could then make early intervention possible,” says Professor Curtis.

“We are focusing on non-invasive, cost-effective diagnostic markers, in the hope that they could one day be used widely as a screening tool for pre-clinical dementia.”

In another project aimed at preserving our memories, Professor Wickliffe Abraham from the University of Otago aims to reveal the fundamental mechanisms that disrupt brain ‘plasticity’ and affect our ability to learn and remember things.

“The ability to form memories is fundamental to all mental abilities, and there are profound consequences when memory function is impaired, including Alzheimer’s Disease, stroke and traumatic brain injury,” he says.

His team will be looking into the role of ‘astrocytes’ – cells that support and help the function of nerve cells in the brain.

“In the past 10 to 15 years, astrocytes and how they work together with the nerve cells has become a real hot topic,” says Professor Abraham. “Under normal conditions, they may be involved in protecting memories from interference, but in the presence of disease they may actually generate memory deficits.”

His study is poised to make a significant contribution to the growing international field of astrocyte biology and our understanding of how memory mechanisms are regulated.

“Understanding these processes may help identify new targets for therapeutic interventions to rescue diseased memory and cognition,” he says.

The HRC’s director of Research Investments and Contracts, Dr Vernon Choy, says this year’s project proposals once again prove that New Zealand researchers are leading the way in identifying novel solutions to difficult problems.

“The projects we’ve funded this year span across public health, biomedical research, Māori and Pacific health. All of them delve into important health issues, and many pose questions that affect us all in some way – they really do have the potential to improve the lives of all New Zealanders.”
