Discovery could inspire new way to detect brain abnormalities

Scientists have taken a promising step towards a new generation of accurate, affordable and portable devices to detect concussion, epilepsy and dementia.

The international research team developed a laser-based diamond sensor that can measure magnetic fields up to 10 times more precisely than standard techniques. Their results are published in Science Advances.

Their innovation could help improve on existing magnetic-field sensing techniques for mapping brain activity to identify disorders. With sufficient funding and collaboration with industry, the team say they could develop a proof-of-concept device using their new sensor within five years.

Concussion in sport has been in the spotlight recently with prominent athletes sharing their stories about the significant ramifications of head injuries sustained during their careers. Meanwhile, about 250,000 Australians live with epilepsy, while nearly 500,000 Australians have some form of dementia.

The research is also relevant to a range of sectors beyond healthcare including mining, where it could lead to improved mineral exploration applications.

The study was led by Fraunhofer Institute for Applied Solid State Physics (IAF) in Germany – one of the leading organisations for applied research in Europe – working with RMIT University experts in diamond sensing technology Professor Andrew Greentree, Professor Brant Gibson and Dr Marco Capelli.

What’s the scientific breakthrough?

Diamond is already used for sensing magnetic fields, where the amount of light that comes from quantum defects in the diamond changes with the strength of the magnetic field.

The problem with today’s approach is that most of that light is lost.

“Our breakthrough was to make a laser from the defects,” Greentree said.

“By collecting all the light – instead of just a small amount of it – we can detect the magnetic field 10 times more precisely with our sensor compared with current best practice.”

How would the portable brain imaging device work?

Today’s magnetoencephalography, or MEG, technology is very sensitive, but also bulky, expensive to install and needs to operate at ultra-cold temperatures with liquid helium and patients must remain still.

“Current MEG machines are huge devices, with dedicated facilities, and they require magnetic shielding around them as well,” Greentree said.

MEG technology based on the new diamond-laser sensor would be much smaller than today’s devices, would operate at room temperature and could be fitted to patients who can move around.

“We really want to have something that we can place on a patient’s head and we want them to be able to move around – and there’d be no need for expensive liquid helium to operate such a device,” Greentree said.

“With Alzheimer’s, you want to be able to monitor the progression of the disease and know the effect of any treatments. It’s similar with concussion, you want to be able to measure what’s happening in the brain after each knock.

“With this MEG technology we envisage, you might be able to pick up early-onset dementia.

“With epilepsy, you could find out where it’s occurring, and that would help you to better target interventions.”

Fraunhofer’s Dr Jan Jeske and Dr Felix Hahl were corresponding authors for this study, which also involved researchers at the National Institutes for Quantum and Radiological Science and Technology in Japan and The College of Staten Island in the United States.

Introduction of New Clinical Care Standard by ACSQHC to Address Psychotropic Medicine Use in Cognitive Disability and Impairment

 

By Jeff Gibbs

The Australian Commission on Safety and Quality in Health Care (the Commission) has today announced the launch of a pivotal new national standard aimed at enhancing the care for individuals with cognitive disabilities or impairments. The introduction of the Psychotropic Medicines in Cognitive Disability or Impairment Clinical Care Standard is a critical advancement in promoting safer and more effective treatment protocols across the healthcare spectrum.

Background and Rationale for the New Standard

Advertisements

Recent decades have witnessed a 60% surge in the prescription of psychotropic medications across Australia. Despite a modest reduction in antipsychotic use among the elderly—prompted by heightened awareness of associated risks—the prescribing rates remain alarmingly high, particularly among vulnerable populations. Notably, older individuals and those residing in aged care facilities are disproportionately affected by the adverse effects of these medications, including cognitive decline, heightened risk of falls, strokes, and mortality. Additionally, approximately one-third of individuals with intellectual disabilities are prescribed psychotropic drugs, exposing them to potentially severe short and long-term side effects.

Scope and Impact of the Standard

The new Standard seeks to mitigate the inappropriate utilisation of psychotropic medications and emphasises patient safety. It priorities non-pharmacological interventions as the foremost approach for managing challenging behaviours such as aggression and agitation. Psychotropic medications are advised as a last-resort measure, following the ineffectiveness of alternative strategies or in situations posing significant risk to the individual or others.

The Standard advocates for tailored non-medication strategies that respect the individual’s needs and preferences, developed in consultation with their family and other authorised caregivers. This approach underscores the commitment to upholding the dignity and autonomy of individuals with cognitive impairments.

Expert Insights and Support

Key health experts have endorsed the significance of this new Standard. Conjoint Associate Professor Carolyn Hullick, Chief Medical Officer at the Commission, stresses the necessity for mindful prescribing practices given the limited benefits and substantial risks associated with psychotropic medications in this demographic. Professor Julian Trollor from the University of New South Wales and Juanita Breen from the University of Tasmania also highlight the importance of objective-driven prescribing, continuous monitoring, and the potential to reduce medication dosages in favour of non-pharmacological alternatives.

Implementation Across Settings

The Standard is applicable universally across various healthcare settings, including hospitals, aged care facilities, and community services, ensuring that individuals with cognitive disabilities receive consistent and coordinated care irrespective of the setting.

Professor Eddy Strivens emphasises the need for coordinated efforts and effective communication, particularly during care transitions, to maintain continuity and efficacy of treatment plans and to support decision-making processes that honour patient autonomy.

Collaborative Efforts for Enhanced Care

In a collective endeavour to address these issues, the Commission has collaborated with the Aged Care Quality and Safety Commission and the NDIS Quality and Safeguards Commission to issue a Joint Statement against the misuse of psychotropics in managing behaviours in disabled and elderly populations.

Conclusion

The introduction of the Psychotropic Medicines in Cognitive Disability or Impairment Clinical Care Standard marks a significant step forward in improving the quality of care and safety for Australians with cognitive disabilities or impairments. It aligns with ongoing efforts to reform health care, aged care, and disability support systems across the nation.

The complete Standard and accompanying resources are available on the Commission’s website here.

National Walk Safely to School Day Turns 25

 

As National Walk Safely to School Day approaches on Friday, 10 May 2024, primary school-aged children across Australia are encouraged to lace up their shoes for a walk towards a healthier future. Celebrating its 25th anniversary, this initiative, championed by the Pedestrian Council of Australia, highlights the myriad benefits of walking and other forms of active transportation, particularly to and from school.

This annual event not only emphasises physical health but also aims to improve road safety, reduce environmental impact, and promote the use of public transport to lessen car dependency near schools. Harold Scruby, Chairman and CEO of the Pedestrian Council of Australia, emphasises the importance of adult supervision for children under 10 when crossing the street, reinforcing the safety aspect of the campaign.

“Walk Safely to School Day is a great opportunity to teach our kids about the benefits of physical activity,” said Scruby. He also pointed to the worrying statistics of childhood obesity, which affects one in four children at critical levels across the nation, according to the latest ABS National Health Survey results from 2017-18. “The best form of physical activity for all Australians is walking regularly. Children need at least 60 minutes of physical activity a day,” he added.

The day is not just about walking; it also encourages schools and parent groups to host healthy breakfast events to start the day nutritiously. This initiative supports the dual goals of fostering healthful eating habits and providing social interaction within the school community.

As the event marks a significant milestone, schools across Australia are gearing up to participate more actively than ever. Parents, teachers, and caregivers are encouraged to get involved, not only to support their children but also to take part in making walking a regular part of their daily routine.

This initiative plays a crucial role in mitigating traffic congestion around school areas, promoting environmental stewardship, and fostering a sense of community. Everyone in the community is invited to support the initiative, helping to instil healthy habits in children that can lead to lifelong benefits.
