In this episode of the Dementia Researcher podcast, host Dr Amanda Heslegrave leads an insightful discussion on one of the most promising developments in dementia diagnostics: blood-based biomarkers.
Once a purely research-focused tool, these tests are now moving closer to clinical practice, offering the possibility of earlier, easier, and less invasive diagnosis of neurodegenerative diseases. But while the science advances rapidly, questions remain about how ready the healthcare system is to adopt them.
Amanda is joined by two expert guests:
Dr Jay Amin, University of Southampton – A clinician specialising in dementia, researching inflammation and immune biomarkers, particularly focused on diagnostics and prognosis.
Dr Mark Roskey, Quanterix – Senior VP involved in developing ultra-sensitive biomarker detection technologies crucial for dementia research.
Together, they explore the current state of play—from recent breakthroughs in markers like p-Tau217 to practical hurdles such as infrastructure, standardisation, and clinician education. They also reflect on ethical considerations surrounding early diagnosis and the importance of cross-sector collaboration to ensure these tools benefit as many people as possible.
Topics Covered:
- The current landscape and promise of blood-based biomarkers
- Recent scientific and technological breakthroughs
- Barriers to clinical implementation and public adoption
- Ethical questions around early diagnosis

Previous Episode
The Minds in Motion Podcast from Dementia Researcher in association with the NIHR Applied Research Collaborations and Alzheimer’s Society, brings together NIHR Dem Comm Research Fellows, to talk about their research and careers.
In this second series, we hear from five of the Dem Comm Fellows each taking a turn as co-host and guest. Alongside the researchers we have the incredible Trevor Salomon, Alzheimer’s Society Volunteer & Chair of the European Dementia Carers Working Group as our permanent co-host and anchor.
In show Trevor is joined by Dr Katie Breheny from Bristol University and NIHR Applied Research Collaboration (ARC) West to interview Dr Pippa Collins.
Pippa Collins is an Advanced Clinical Practitioner and NIHR / Alzheimer’s Society Dem Comm Fellow based at the University of Southampton and NIHR ARC Wessex. Her research primarily addresses the critical aspects of end-of-life care, frailty, and dementia. In this discussion, we explore her work aimed at enhancing the recognition and management of the end-of-life period for people living with dementia. Pippa highlights the importance of shifting from traditional medicalised models of palliative care towards a holistic and personalised "palliative approach," focusing on recognising individual trajectories and vulnerabilities. Her goal is to foster improvements in dementia care practices by better educating healthcare professionals, supporting families, and integrating patient-centred care pathways that respect each individual's emotional, social, and cognitive needs.
Dem Comm is a 2 year programme funded by the National Institute of Health and Care Research and the Alzheimer's Society. It supports a new generation of dementia research leaders, bringing together researchers from different multidisciplinary backgrounds to encourage cross-cutting and community-orientated dementia research projects that can address key gaps in the evidence around dementia care and support, delivering transformative translational research.

Next Episode
In this final episode of the current series, Trevor Salomon is joined by Dr Pippa Collins from the University of Southampton to interview Dr Sarah Kate Smith.
Sarah is based at The University of Manchester and NIHR ARC Greater Manchester, and is an NIHR and Alzheimer’s Society Demm Comm Fellow. Her work focuses on brain health and dementia prevention, particularly examining how physical activity in midlife could reduce the risk of developing dementia later in life. With a background in psychology and a PhD in health services research, Sarah brings expertise in creative and inclusive research methodologies that enable the involvement of people living with dementia and their families.
In this conversation, we explore the challenges of dementia prevention research, how risk reduction differs from the idea of outright prevention, and the importance of public and patient involvement in designing ethical and accessible interventions. Sarah also shares insight into an upcoming project exploring access to brain health clinics among minority ethnic groups and reflects on her career journey, motivations, and what keeps her going.
