Hope on the horizon for dementia: Interview with Dr Iain Hartnell from the Alzheimer’s Society
Dementia is a condition that has long been met with fear, confusion, and a sense of helplessness. However, in recent years, there has been a wave of optimism, with significant breakthroughs in both diagnosis and treatment.
Dr Iain Hartnell, Research Communications Officer at Alzheimer’s Society, shares his insights on the progress being made in dementia care.
“This is the most hopeful time there has been for dementia since Alzheimer’s Society started,” says Dr Hartnell in his interview with ITN Business, as part of our Redefining Later Living programme. “We now have two drugs approved in the UK by the MHRA. They’re not approved for the NHS, but they’re approved for use in the UK. This is really hopeful. They’re called Donanemab and Lecanemab.”
These drugs, though not yet available on the NHS, represent a major leap forward in dementia treatment, with their approval marking a significant milestone in the battle against Alzheimer’s disease. “That has led to breakthroughs in diagnosis as well,” Iain continues. “Now blood testing is being researched, and Alzheimer’s Society are partners in a program called the Blood Biomarker Challenge, which is trying to get a blood test for Alzheimer’s or other dementias into the NHS.”
This blood test, still in the research phase, could dramatically alter the way dementia is diagnosed. “This will get people diagnosed much quicker, because they can just go to the GP to have their blood tested, and then if the marker shows that they do look like they have a form of dementia, they can perhaps get slightly more invasive tests,” explains Iain. “But that blood test in the future might even be enough by itself.”
The potential for a simple blood test to diagnose Alzheimer’s and other dementias is a game-changer, allowing for earlier intervention and more effective management of the condition. These developments, combined with the promising drugs now available, offer more hope than ever before.
Preventing dementia: What lifestyle changes can make a difference?
While treatment options are advancing, Iain also highlights the importance of prevention. According to a recent report commissioned by the Alzheimer’s Society, around 50 per cent of dementia cases could be delayed or prevented through lifestyle changes. “The report looked into lots of different factors that could affect somebody’s risk of dementia, and they outlined 14 different factors,” says Iain. “These range from medical things like high blood pressure, diabetes, hearing loss, to things like smoking, drinking excess alcohol, and other things like air pollution; lots of these things can be mitigated.”
Adopting a healthier lifestyle can significantly reduce the risk of developing dementia. “Then there are other lifestyle changes that people can make like doing more exercise. We know that what’s healthy for the heart is also healthy for the brain, because blood vessels are involved in dementia and keeping your blood vessels healthy is another good way; so that’s exercise, eating healthily, and things like that.”
By focusing on heart health, people can simultaneously protect their brain health, making simple lifestyle adjustments crucial in the fight against dementia.
Combating stigma and encouraging early diagnosis
Despite growing awareness, dementia still carries a stigma, and Dr Hartnell believes that one of the barriers to proper diagnosis and care is a lack of understanding. “I think it’s a lot to do with misunderstanding or lack of understanding about dementia. And partly it’s to do with fear… which is totally understandable. It’s not a nice disease.”
However, he emphasises that support is available for those living with dementia. “There are lots of people like outside the society who people can go to for support to help them live for longer in their homes, help them manage all of those daily tasks, and also connect them with other people with dementia so they can be with people who understand what they’re going through.”
Unfortunately, there are still many individuals who are reluctant to seek help. Dr Hartnell points out that around one-third of people living with dementia in the UK do not have a diagnosis. “This could be partly because they live alone, so they are unaware that they have a problem, or there’s those people who understand that they have a problem, but perhaps don’t know what it is, and are too scared to find out what it is.”
But there is good news on the horizon. “Up until these drugs were announced, there wasn’t any disease-modifying drugs or any drug that could slow down the progression of the disease that was available in the UK, but now there is a lot of hope for the future,” says Dr Hartnell.
With over 20 drugs currently in late-stage clinical trials, many of which show promise in slowing the progression of dementia, the future is looking brighter. “So that’s really hopeful, as well as the diagnosis piece and getting blood tests into the NHS which will make getting a diagnosis in the first place much easier.”
A future of possibilities
As the medical community makes strides in both treatment and diagnosis, the future for dementia patients and their families looks more hopeful than ever before. Early diagnosis, new drugs, and lifestyle changes all play a vital role in managing and even preventing dementia, offering a new sense of optimism for millions.
In Iain’s words, “This is the most hopeful time there has been for dementia since Alzheimer’s Society started.” With more breakthroughs on the horizon, the fight against dementia is gaining momentum, and hope is becoming a reality for those who need it most.
