Scotland’s Dementia Drug Trial Gap: A Tipping Point for Future Alzheimer’s Treatments?
Imagine a future where a simple blood test can predict your risk of Alzheimer’s decades before symptoms appear, and personalized treatments are readily available to slow – or even halt – the disease’s progression. While this scenario feels distant, the current landscape of dementia research, particularly in Scotland, reveals a critical juncture. Roy Mitchell, one of the first four participants in a new Alzheimer’s drug trial in Edinburgh, embodies a growing hope, but also highlights a stark disparity: Scotland is lagging behind in providing access to these potentially life-altering clinical trials.
The Promise of THN391 and a Shift in Treatment Focus
Unlike recent Alzheimer’s drug breakthroughs focusing on amyloid proteins, the trial Roy is participating in centers around THN391, a medication targeting fibrin – a protein linked to inflammation and blood vessel damage in the brain. This represents a significant shift in therapeutic approach. While still in its early stages, the trial offers a crucial opportunity for patients like Roy, who, after a devastating diagnosis in November 2022, were initially told by healthcare professionals that his condition would inevitably worsen. “They sent us away with a leaflet and told Roy would die of the disease,” recalls his wife, Kirsty Mitchell. The trial, funded by pharmaceutical companies and run by Scottish Brain Sciences, provides a glimmer of hope where the NHS currently offers limited options.
“It gives me hope that it opens the door for newer therapies that might be more appropriate for the NHS in Scotland and beyond,” says Dr. Meher Lad, Clinical Lead at Scottish Brain Sciences. “We are perhaps at the tipping point where we can make this happen.”
A Disparity in Trial Access: Cancer vs. Dementia
The stark reality is that access to dementia drug trials in Scotland significantly trails behind other areas of medical research. In 2023-24, around 1,000 patients participated in dementia trials, compared to over 3,000 in cancer trials and more than 4,000 in cardiovascular drug trials. This isn’t due to a lack of need – Alzheimer’s is a leading cause of death in Scotland – but a critical infrastructure gap. Henry Simmons, CEO of Alzheimer Scotland, emphasizes the intensive nature of new dementia treatments, requiring specialized scanners, IV infusion centers, and robust diagnostic capabilities.
“When you think about cancer drugs and cancer treatments, you’ve got the Beatson, you’ve got an infrastructure, everywhere’s got a really big economy of scale to build on,” Simmons explains. “When it comes to treatments for people with dementia, there’s none of that.”
The Cost of Innovation: Why Promising Drugs Are Being Rejected
The issue isn’t solely about infrastructure; cost plays a significant role. Two recently approved drugs, donanemab and lecanemab, shown to slow early-stage Alzheimer’s, were rejected by the Scottish Medicines Consortium (SMC) due to their cost and the associated expenses of required scans and appointments. This highlights a systemic challenge: the NHS in Scotland, operating within fixed budgetary constraints, struggles to accommodate the financial demands of innovative, albeit expensive, treatments. This situation underscores the need for a fundamental shift in how dementia research is funded and prioritized.
Did you know? Alzheimer’s disease and other dementias cost the UK economy an estimated £30 billion per year, a figure projected to rise dramatically as the population ages.
Future Trends: Blood Tests, Early Detection, and Personalized Medicine
Despite these challenges, several promising trends are emerging. The development of blood tests capable of detecting Alzheimer’s at an early stage is a game-changer. These tests, moving from research labs into clinical settings, will enable earlier diagnosis and intervention, potentially maximizing the effectiveness of future treatments. Furthermore, the focus is shifting towards personalized medicine, tailoring treatments to individual genetic profiles and disease characteristics. This approach, coupled with advancements in neuroimaging and data analytics, promises to revolutionize dementia care.
The Rise of Digital Biomarkers and Remote Monitoring
Beyond blood tests, digital biomarkers – data collected from wearable sensors and mobile devices – are gaining traction. These technologies can track subtle changes in gait, sleep patterns, and cognitive function, providing valuable insights into disease progression. Combined with remote patient monitoring, these tools can enable more frequent and convenient assessments, reducing the burden on healthcare systems and improving patient engagement.

Investment and Collaboration: The Key to Progress
However, realizing this future requires significant investment and collaboration. Alzheimer Scotland is advocating for increased funding from both the Scottish and UK governments, urging a strategic approach to attract private investment and foster partnerships between pharmaceutical companies, universities, and the NHS. Scotland has the potential to become a global hub for dementia research, but this requires a concerted effort to build the necessary infrastructure and expertise.

Frequently Asked Questions
Q: What is the difference between donanemab and lecanemab?
A: Both donanemab and lecanemab are monoclonal antibodies designed to clear amyloid plaques from the brain, a hallmark of Alzheimer’s disease. While both showed promise in slowing cognitive decline in clinical trials, they have different mechanisms of action and potential side effects.
Q: How can I reduce my risk of developing Alzheimer’s disease?
A: While there’s no guaranteed way to prevent Alzheimer’s, adopting a healthy lifestyle – including regular exercise, a balanced diet, cognitive stimulation, and social engagement – can significantly reduce your risk. Managing cardiovascular risk factors like high blood pressure and cholesterol is also crucial.
Q: What is the role of the Scottish Medicines Consortium (SMC)?
A: The SMC is the body responsible for advising the Scottish government on the use of new medicines within the NHS. They assess the clinical effectiveness and cost-effectiveness of drugs before making recommendations about their availability.
Q: What is the future of dementia research in Scotland?
A: The future hinges on increased investment in infrastructure, fostering collaboration between research institutions and the pharmaceutical industry, and embracing innovative technologies like blood tests and digital biomarkers. Scotland has the potential to be a leader in dementia research, but it requires a strategic and sustained commitment.
The story of Roy Mitchell is a powerful reminder of the human cost of inaction. As research progresses and new treatments emerge, ensuring equitable access to clinical trials and innovative therapies will be paramount. The tipping point is near – will Scotland seize the opportunity to become a beacon of hope in the fight against Alzheimer’s disease?
