Why is rapid stepping impaired in dementia? 💡 Our fNIRS data revealed right DLPFC hyperactivation during simple stepping, but a blunted response as cognitive demands rose—highlighting a premature prefrontal ceiling during step control. 🔗 doi.org/10.1007/s11357-026-0…

Dementia prevention isn't just an individual choice 🏛️ Our @JECH_BMJ study shows staying active protects across all strata, but socioeconomic status dictates access to engaging activities. Prevention needs equity. Paper: doi.org/10.1136/jech-2026-22…

Can everyday engagement buffer dementia risk? 💡 Tracking 500k+ people over ~15 yrs, we found higher behavioural engagement was linked to 17% lower dementia risk—led by <2 hrs/day TV & diverse leisure activities! Read in @JECH_BMJ: doi.org/10.1136/jech-2026-22…

Using 48-channel fNIRS, we examined prefrontal network topology during stepping in dementia vs healthy aging. Key finding: Greater prefrontal network segregation correlated with faster choice stepping reaction time! 🔗 doi.org/10.1007/s11357-026-0…

Excited to share our new @JECH_BMJ study on 500k+ @uk_biobank participants! 🧠📊 We decoupled upstream SES, education/job complexity & daily activity patterns to see how they uniquely predict incident dementia. doi.org/10.1136/jech-2026-22…

Can "pure" cognitive training make older adults better walkers? Our systematic review in JMIR Aging reveals cognitive training enhances dual-task gait speed, but doesn't directly transfer to simple balance or single-task walking. aging.jmir.org/2026/1/e85070

Does brain training help older adults walk safer? Our new review found cognitive training targeting executive function (40–60 min, 2–3x/week for 8–10 wks) boosts dual-task walking speed! 📖 Full paper: aging.jmir.org/2026/1/e85070

Excited to share our latest paper in @JMIR_Pub! Can pure cognitive training improve gait & balance in older adults? Our systematic review & meta-analysis shows it significantly improves walking speed during dual-task conditions. 🔗 aging.jmir.org/2026/1/e85070

Excited to share that my recent grant application to the Health and Medical Research Fund has been approved. I’m honoured to receive HKD 1.5 million in funding to support our project on evaluating the effects of #exergaming on balance and #FallsPrevention.

Greqat news! My study on using Nintendo Ring Fit Adventure™ for fall prevention has been named a top cited article of 2024 in the Australasian Journal on Ageing. I hope this inspires more innovation in using tech to keep older adults active and engaged. doi.org/10.1111/ajag.13297

Have you registered for the 3rd World Falls Congress? The early bird registration will end tomorrow on 24 Mar 2026. Looking forward to meeting all people from different parts of the world who are keen to study falls prevention! bgs.org.uk/WFC26

It is my great pleasure to be part of the event organized by the Jockey Club Smart Ageing Hub. We should organize more events like this to let people know that we have many different ways to prevent falls and reduce fall-related injuries. youtu.be/LcHmqNQ5JgQ?si=P1Lz…

tDCS targeting a single brain region yields similar improvements in global cognition compared to multi-target stimulations. Stimulating left frontotemporal lobe and left DLPFC yielded significant improvements in global cognition. doi.org/10.1016/j.jpsychires…

The Asian Falls Network Webinar Series in April! This time, we have invited experts from Pakistan and the Philippines to share their critical research and practical intervention strategies for fall prevention. Join the webinar using the QR code!

New publication alert! Our latest published feasibility trial demonstrates that step training incorporating cognitive-motor tasks is both safe and achievable for older adults with mild-to-moderate dementia. doi.org/10.1177/138728772614…

Traditional rTMS can improve ADLs in people with cognitive impairment. The effects on ADLs are small post-intervention and moderate at follow-ups. The effects in people with AD are particularly more prominent. doi.org/10.1016/j.jpsychires…

Stepping performance, measured by Four Square Step Test, Choice Stepping Reaction Time Test, and Alternate Step Test, is moderately to strongly associated with mobility, global cognition, and functional independence in older adults with dementia. ira.lib.polyu.edu.hk/handle/…

Stronger connectivity between the default mode and fronto-executive networks acts as a protective mechanism in cognitively frail individuals. This enhanced connection moderates the negative impact of cognitive instability on mobility. doi.org/10.3389/fnagi.2025.1…
