The link between eye health and dementia
Researchers at the University of Otago have discovered changes to the blood vessels at the back of the eye may indicate someone is at greater risk of developing dementia.
Dr Ashleigh Barrett-Young is the co-lead author of the study.
She is a Research Fellow in the Department of Psychology, University of Otago/Ōtākou Whakaihu Waka.
Susie asked Ashleigh what researchers have been looking for and what those discoveries mean.

Dental Advocacy Group Calls For Action On Dental Costs To Deal With Cost Of Living Pain
A group advocating for improved access to dental is calling on the Government to bring dental into the public healthcare system to ease cost of living pain. Dental for All - a group of dentists, oral health therapists, unions, and poverty action groups - says that recently released research shows rising dental costs are adding to the strain faced by households. New 2025 research published by University of Otago academics shows that between 1978 and 2023, fees for five core dental treatments increased by 75%-236% while earnings went up by 46%. Hana Pilkinton-Ching, Dental for All spokesperson, said: "We already knew that dental care was cost-prohibitive, with almost half of us unable to afford it, but this latest research shows households dealing with high food and gas costs are also facing rising dental costs for essential care." The New Zealand Health Survey for 2023-2024 showed that 45% of people in New Zealand were unable to access dental care because of cost. Pilkinton-Ching added: "We are calling on the Government to address this as a matter of urgency. There's no good medical or policy reason why dental is carved out of our public healthcare system, and with dental costs continuing to rise the Government needs to get a grip on this." Research shows that untreated oral healthcare problems are associated with downstream health problems, including cardiovascular disease, diabetes, and cognitive decline and Alzheimer's. Work previously produced by Dental for All shows that keeping dental out of our public healthcare system is costing New Zealand $2.5bn in lost productivity and $3.1bn in reduced quality of life. The Dental for All coalition continues a roadshow this week, travelling this evening to Whanganui, followed by further events in the coming days in New Plymouth, Hamilton, and Rotorua.

Exercise physiology students helping folk stay mobile
Jeffrey Batts reckons if he can get in or out of his car without his leg locking up, he is having a good day. The 63-year-old has arthritis in his right hip, which flares up from time to time, sometimes leaving him unable to move. "It's sort of like the hip's jamming. "If I put my leg in the wrong position, then I can't move the leg and it goes into spasm. "Then I have to call the ambulance — or like the other day, this lady saw me in trouble and gave me a ride to my house." Mr Batts said he had prescribed painkillers to help with the pain, and he was trying to get an appointment with a specialist so he could get a hip replacement. But in the meantime, he was hoping students at the University of Otago's Connection Through Movement Studio might be able to help him manage the pain and stay mobile enough to do everyday activities. "I can't do quite as much as I used to do, you know. "Just getting into the car, that's enough to set it off." Mr Batts is one of about 45 members of the Dunedin community who attend the studio each week. University of Otago postgraduate clinical exercise physiology student Aliya Mottus is part of a group of clinical exercise physiology students who have created the studio, where they work with members of the Dunedin community with illnesses or ailments, to help improve their wellbeing. She said they created personalised exercise programmes for each client and ran a range of group sessions, such as pregnancy classes and the "Strong and Steady" programme, which helped people with balance issues. "We work with people who have cardiovascular conditions like hypertension, people that have had heart attacks or coronary artery disease. We've got a couple of people with chronic fatigue or neurological conditions, people with different types of arthritis, people with diabetes — even some with cancer are coming through." She said exercise physiology aimed to help people maintain or re-establish physical capacity, especially those with degenerative conditions. "If you can help maintain that as long as possible, it helps improve overall quality of life." The studio had been running for about 10 weeks and clients had already made major progress, including some who could now touch their toes, climb the stairs to their front door, or ride a bike. "They may seem like really little things, but they're really big wins for our clients, which is so rewarding for us to see." While the studio was helping people in the community, it was also helping the students to build the 360 clinical hours to get their accreditation with Sport and Exercise Science New Zealand or Clinical Exercise Physiology New Zealand. "So this functions as an outlet for us to work with people with different complex and chronic conditions." The studio would remain open until November 7, and would continue to operate next year.

Science: Walking for your heart, black carbon underestimated
Is walking backwards really the key to fast-forwarding your fitness? Photo: 123rf Science correspondent Laurie Winkless joins Susie with three new studies. The first has found that taking more steps - even below the recommended 10,000 target - and increasing your walking pace are associated with reducing your risk of a heart event or stroke. Black carbon emissions in the 'global south' are almost 40 percent higher than previously reported. And researchers in Japan have developed the strongest underwater adhesive hydrogel to date.
