UK to Begin Nationwide Blood Test Trials for Dementia – Neuroscience News

Published

 on


Summary: The UK is set to conduct nationwide trials to evaluate the effectiveness of blood tests in diagnosing dementia. The Blood Biomarker Challenge aims to validate potential blood tests for clinical use in the NHS within five years.

These tests, which show promise in identifying Alzheimer’s disease and other dementias through biomarkers like p-tau217, could revolutionize diagnosis, facilitating earlier and more accurate detection. This initiative addresses the urgent need for accessible diagnostic methods, especially in light of potential new treatments for Alzheimer’s disease on the horizon.

Key Facts:

  1. The trials leverage recent breakthroughs in blood tests for dementia, aiming to introduce them to NHS practice within five years.
  2. Led by top UK research institutions, the studies will focus on biomarkers for Alzheimer’s and other dementias, testing their efficacy in a diverse UK population.
  3. Funded by a multi-million-pound award, this initiative promises to significantly enhance dementia diagnosis, ensuring equitable access to emerging treatments.

Thousands of people in the UK are to take part in countrywide trials to identify accurate and quick blood tests that can diagnose dementia, led by research teams at UCL and Dementias Platform UK, based at the University of Oxford.

The trials will capitalise on recent breakthroughs in potential dementia blood tests to generate the evidence needed for them to be used in the NHS within the next 5 years.

Together, the research teams make up the Blood Biomarker Challenge – a multi-million-pound award given by Alzheimer’s Society, Alzheimer’s Research UK, the National Institute for Health and Research and Gates Ventures, including £5m raised by players of the People’s Postcode Lottery. The project aims to revolutionise dementia diagnosis.

Both teams will recruit participants from sites spread across the country, to ensure their findings are applicable to the whole of the UK’s diverse population.

Timely and accurate diagnosis of the diseases that cause dementia, such as Alzheimer’s disease, is crucial as it means people can access vital care and support and take part in medical research. This will be even more imperative if new treatments are approved for use in the NHS, as these work best for people in the earliest stage of their disease. 

Currently, people are usually diagnosed using memory tests and brain scans. These are less accurate than ‘gold standard’ tests like PET scans or lumbar punctures, which can confirm what type of dementia they have. However, only 2% of people can access these specialist tests.

In recent years, a number of different blood tests that can diagnose Alzheimer’s disease and other causes of dementia have shown very promising results in research settings. But they have yet to be tested widely in clinical settings in the UK. 

Led by Professor Jonathan Schott (UCL Queen Square Institute of Neurology, honorary consultant neurologist at UCLH, and Chief Medical Officer at Alzheimer’s Research UK) and Dr Ashvini Keshavan (UCL Queen Square Institute of Neurology), the Alzheimer’s Disease Diagnosis and Plasma p-tau217 (ADAPT) team will focus on the most promising biomarker for Alzheimer’s disease, called p-tau217.

This reflects levels of two hallmark proteins found inside the brain in Alzheimer’s disease – amyloid and tau. The researchers will carry out a clinical trial to see whether measuring p-tau217 in the blood increases the rate of diagnosis for Alzheimer’s disease both in people with early dementia, but also in those with mild, progressive problems with memory.

Professor Schott said: “An early, accurate diagnosis of Alzheimer’s disease is already important, allowing people to access appropriate care and medications. If, as we hope, new treatments that can slow down Alzheimer’s disease become available soon, then this will be vital.

“This would pave the way for fair and equitable access to new and potentially life-changing treatments to all who might benefit.”

The Real World Dementia Outcomes (READ-OUT) team will be led by Dr Vanessa Raymont, Associate Director at Dementias Platform UK and a Senior Clinical Researcher at the University of Oxford, alongside other researchers including some from the University of Cambridge.

They will test multiple existing and novel blood tests, looking at a range of types of dementia, including Alzheimer’s disease, vascular dementia, frontotemporal dementia, and dementia with Lewy bodies. The researchers will also look at whether blood tests can help detect these diseases at various stages.

Dr Raymont said: “Since I first stepped into a memory clinic 30 years ago there has thankfully been a shift in the way society thinks about dementia. There was previously a feeling that this was just another part of ageing, but now we’re seeing that people want to know more about their condition and they want a diagnosis as it helps them access the support they need.

“Both my parents lived with dementia so I know firsthand the devastation this disease causes, and how a timely and accurate diagnosis can benefit people and their families.”

These complementary approaches will maximise the chances of providing the evidence needed to prove that blood tests are ready for use in the NHS, and will pave the way for them to be made available within the next 5 years.

With more than half of all local authority districts in England failing to meet the government’s target dementia diagnosis rate of 66.7%, and with new drugs on the horizon which appear to slow early Alzheimer’s disease, experts from both charities and the research teams agree that change is needed.

Fiona Carragher, Director of Research and Influencing at Alzheimer’s Society, said: “At the moment only 2% of people with dementia can access the specialised tests needed for a diagnosis, leading to unnecessary delays, worry and uncertainty. Blood tests are part of the answer to this problem – they’re quick, easy to administer and cheaper than current, more complex tests.

“I’ve spent decades working in research and the NHS and, after years of slow progress, it feels like we’re on the cusp of a new chapter on how we treat dementia in this country.”

And Dr Sheona Scales, Director of Research at Alzheimer’s Research UK, added: “We’ve seen the enormous potential that blood tests are showing for improving the diagnostic process for people and their loved ones in other disease areas. Now we need to see this same step-change in dementia, which is the greatest health challenge facing the UK.

“It’s fantastic that through collaborating with the leading experts in the dementia community, we can look to bring cutting-edge blood tests for diagnosing dementia within the NHS. And this will be key to widening access to groundbreaking new treatments that are on the horizon.”

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
