Dementia affects around 50 million people globally, a number that is tipped to triple in the next 30 years. Researchers are tackling the issue on all fronts, with investigations ranging from genetics to lifestyle risks and treatments. With no cure yet, one key question focuses on prevention: Can we slow the rate of cognitive decline to avoid dementia?
The Spencer Bennett Neuromusic Collaborative aims to find out.
Enabled by a generous philanthropic gift, this three-year program will test whether music training workshops are a feasible cognitive training intervention for people experiencing mild cognitive decline - the stage before dementia develops.
Through an intensive music training course, imaging studies, and neurological and psychological testing, the program will provide evidence for what happens next in this space: a new field of research, broader studies, and music training programs for cognitive intervention within community settings.
Philanthropic donations fill a gap in the research funding landscape. They broaden the scope of research by enabling us to explore ideas and develop programs of research that sit outside the remit of traditional funding programs.
They also give members of the community a direct way to build on our collective knowledge and ultimately, impact the lives of others.
The Spencer Bennett NeuroMusic Collaborative stemmed from conversations between Barbara Spencer and the Brain and Mind Centre's (BMC) development team. Barbara described her vision for a gift that would create new research parameters and lead to the possibility of health benefits for people affected by dementia. She expressed interest in prevention, a key focus of the Healthy Brain Ageing Clinic. As the conversations unfolded, Barbara reflected on the central role of music in the life she and Mr Bennett shared over their 49 years together.
“I am delighted that SCM has such a key role in this research. As an alumnus, it was Lance’s wish to endow the University of Sydney and I feel he would give this research the high priority that I do. We can all truly make a difference by supporting research of quality.”
This research program brings her vision to life. And for the 485,000 Australians who are affected by dementia, the gift has the potential to make life better.
The research team launched the Neuromusic collaborative at the Conservatorium in March 2022. Thanking Mrs Spencer, the Brain and Mind Centre's co-director, Professor Matthew Kiernan and Conservatorium Director, Professor Anna Reid, said this unique gift would have an impact for years to come.
Neuroplasticity is the brain's ability to reorganise itself by forming new neural connections throughout life. It allows the neurons in the brain to compensate for and respond to new situations or to changes in their environment - like illness or injury.
Lead investigator, Professor Sharon Naismith, says neuroplasticity is supported by cognitive training. Activities that require effort, repetition, and adjustment (learning from mistakes) stretch us, which helps protect our neuroplasticity.
"Training, acquiring and mastering new skills and knowledge is 'cognitive reserve', which is listed as one of the 12 known lifestyle factors affecting a person's risk of developing dementia.
"Musicians know this type of training intimately. In neuroscience, we have results from other studies tracking cognitive training, but there is still very little scientific evidence to show how it could be used to help people who may be at risk of developing dementia.
"This is an exciting opportunity to lay down that evidence and take that extra step towards reducing cognitive decline."
Professor Neal Peres Da Costa, Associate Dean of Research at the Sydney Conservatorium, has spent his life with music. He says it is worth learning from the experience of musicians.
"There are so many facets to music training and engagement. For example, working in an ensemble such as an orchestra could have implications for brain health: here, musicians are trained to listen and pick up on one another’s cues; they draw on fine motor skills, and often have committed the music to memory over years of training, rehearsals, and concerts. And, importantly, there is much social interaction.
"Additionally, learning to play an instrument or to sing involves a complex interplay of simultaneous motor and cognitive functions that may differ depending on the type of instrument or voice, demand for rhythm and fine muscle coordination, and motivation for learning, among other things. We also know music has a calming influence on listeners.
"While learning to play an instrument or to sing, as well as engaging with music in general is a fantastic endeavour at any age, we want to harness the potential benefits to improve brain health, so we need to understand which musical ingredients that may help to prevent cognitive decline. Without this evidence to show what is going on in our brains when we put all of this together and make music, we don't really know its full potential," Professor Peres Da Costa said.
"This is an exciting opportunity to investigate the science behind music-making and its potentially transformative power."
During the program's first phase, researchers from BMC and SCM will work with small focus groups of participants enrolled in the Healthy Brain Ageing (HBA) Clinic. The focus groups provide the framework for the design of the music training workshops that will be offered as part of the study.dy.
Researchers will then offer music training to older adults with concerns about cognitive decline and who have been assessed by the HBA Clinic. At this stage, workshops are not open to wider participation as this marks the feasibility study, which measures the impact of music training on a small group of participants.
Participants of the feasibility study volunteer to be assessed at three points over the course of training:
— Magnetic resonance imaging (MRI) will capture any changes in brain structure, such as loss of mass in key areas associated with Alzheimer's disease.
— Psychometric assessments will test learning, memory consolidation, speed of processing and other cognitive factors.
— Surveys and interviews will also measure the psychosocial characteristics, such as self-reported mental health and well-being factors.
To account for the known health benefits of social engagement, which may also contribute to any observed changes, a second group of participants may join in a social music series that fosters similar social interactions.
We hope that in three years we will have the evidence that sets the stage for music training programs that could be provided in community settings or public health services.
