The @UN declaration on noncommunicable diseases (NCDs) has explicitly included dementia. At @LancetGH we discuss how countries can take real action to prevent dementia when it is treated like other major diseases. Preventing dementia needs to go beyond individual choices, with coordinated actions to improve education, health systems and living conditions. Led by @SimoneSalemmeMD & @seb_walsh. #PLADRR. thelancet.com/journals/lanpu…

Dementia prevention faces a paradox: Behavior-focused prevention can widen inequalities when structural barriers persist. Out at the @WHOBulletin, we propose shifting from single individual focus to population-level, equity-driven action across the life course: bit.ly/45io5td

How do we prevent as much future dementia as possible?
A one-page summary of my PhD research into population-level approaches to dementia risk reduction available here: cph.cam.ac.uk/sites/default/…

🚨In this new systematic review, most of the 18 studies reported dynamic associations between lifecourse socioeconomic change and dementia risk. Highest risk for those born poor who stay poor.

"Interventions that reduced socioeconomic inequalities were those implemented and enforced across entire populations/systems or...were supportive and tailored to the differing needs of individuals across socioeconomic groups in their design and delivery."

Alzheimer's disease outlook: controversies and future directions thelancet.com/journals/lance…
Out of 800+ studies on blood-based biomarkers for Alzheimer's, not a single one measured actual changes in patient outcomes.

A key (often ignored) aspect of Alzheimer's research is translating findings between familial disease, specialist clinics, and general population. Here we identify key unanswered research questions and describe a framework for knowledge integration

This is exactly how I've come to see deprescribing.
All other outcomes held the same, it is better to be on fewer medicines than more.
The burden of more medicines should be to prove they add benefit and not the other way around
Nice write-up of this NEJM paper by @drjohnm in the Sensible Medicine substack

New paper with @JanetJanbek using 🇩🇰 registry data to examine prevalence/co-occurrence of dementia risk factors. 82% of people >65 have multiple risk factors, speaking to the need for upstream public health action. More work soon from this collaboration!

We assume the built environment affects how active we are but solid evidence lacking
Important 🇺🇸 paper using📱data to show moving from less walkable neighbourhood to more, or vice versa, has meaningful effect on activity, sustained 3 months after moving

What evidence do we have on the Social Determinants of Dementia (SDOD)?
Delighted that this scoping review, a year or so in the making, is now published in @alzdemjournals. Expertly led by Anouk Geraets, we identified...

The hope is that this provides a platform for people starting out in the dementia research field to make it easier to incorporate an SDOD lens, by knowing what evidence we do have and where the gaps are

Interested? Take a read (it's open access) and get in touch.
Big thanks to co-authors, brought together under the @DEMONNetworkUK

Join me in Toronto or online, for the @alzassociation’s #AAIC25! I'm excited to be speaking on dementia prevention a necessary worldwide agenda on 31st July. New findings synthesised with old. Hope to see you there to say hi at the world’s largest dementia research conference – at Camden Town, London
