Plain English summary of protocol

Background and study aims
Nearly one million people in the UK have dementia, but only about two-thirds have been formally diagnosed. Early detection of memory problems is difficult in routine practice, and waiting times for specialist assessment are often very long — often exceeding 13 weeks when the recommended benchmark is 6 weeks. This puts pressure on NHS memory services, and delays care.

PuntoTest is a simple speech-based tool using artificial intelligence to screen for memory problems. It can be used by patients themselves or with support from a clinician, offering a flexible and accessible approach to early detection. The tool has already been tested in other countries with promising results. This study tests whether it works well in NHS memory clinics and GP practices, and whether it's practical to use in the UK.

Who can participate?
Patients aged 50 years or over who have concerns about their memory, mild memory problems, mild dementia, or no memory concerns (as a healthy comparison volunteer) and have had a recent memory assessment (ACE-III within the last 3 months), or can do this as part of the study

What does the study involve?
The study involves a single visit lasting about 30 minutes. Participants will answer a few basic questions about themselves at the start, then speak into a tablet to complete a simple memory screening tool, and also take a standard memory test (ACE-III) so we can compare results. No additional visits needed.

What are the possible benefits and risks of participating?
Benefits: Participation will help us understand whether PuntoTest could support earlier and more accurate memory assessments in the NHS. This could benefit many people with memory concerns in the future and help improve the way care is delivered. Taking part may not directly benefit participants personally. However, the ACE-III assessment, which is completed during the same visit, is already part of the standard care.

Risks: Minimal. There are no known medical risks associated with taking part. The assessment involves speaking into a tablet and completing a standard memory test. Both are low-risk activities. Some people may find a memory assessment slightly tiring or stressful, or may feel worried about the results. If participants find it difficult at any point, they can speak to the research team. Participants are free to stop at any time.

Where is the study run from?
The study is sponsored by PuntoHealth Ltd and conducted across four NHS sites in England.

When is the study starting and how long is it expected to run for?
The study is expected to start in September 2026, depending on site setup. Enrolment of participants is planned over approximately 12 months (from September 2026 to July 2027). Data analysis is anticipated to be completed by December 2027, although this date is indicative and may change depending on recruitment progress and data collection completion.

Who is funding the study?
1. The National Institute for Health and Care Research (NIHR) Invention for Innovation (i4i) FAST Programme.
2. The UK Science and Technology Facilities Council (STFC)-UK Research and Innovation (UKRI).

PurposeScreening
Scientific titlePuntoTest: speech-based AI cognitive screening in NHS primary and secondary care
Study acronymPuntoTest
Study objectives Primary Objective
To assess the feasibility of implementing PuntoTest within NHS primary and secondary care settings.

This includes:
1. The ability to recruit the target number of participants across sites
2. Participant completion rates of the PuntoTest assessment
3. The feasibility of recruitment pathways from both primary and secondary care

Secondary Objectives
1. To compare performance of PuntoTest with current gold standard cognitive assessment, ACE-III (Addenbrooke's Cognitive Examination-III) and further develop the model.
2. To assess variation in performance across demographic groups, including age, sex, and education
3. To explore participant experience and acceptability of the PuntoTest assessment through qualitative interviews
4. To generate preliminary health economics data to inform future NHS commissioning decisions and grant applications

InterventionStudy Design
This is a multi-site feasibility study designed to assess the implementation of PuntoTest within NHS primary and secondary care settings. This includes embedded health economic assessments, as well as exploratory evaluation of performance against the current gold standard.

What Happens to Participants
Eligible participants are identified by clinical staff at each site as part of their routine care pathway. The Patient Information Sheet (PIS) is provided in advance by the treating clinician or GP, allowing participants at least 24 hours to consider participation and ask questions. If they are interested, a study visit is arranged, where a trained member of the research team will explain the study and obtain written informed consent prior to any study procedures.

At the clinic or GP visit:
1. The research nurse answers any questions and takes written informed consent (15-30 minutes).
2. The participant completes the 10-minute PuntoTest assessment on an iPad in the clinic room, which includes a brief collection of demographic information (such as age, sex, and education level) followed by the speech-based assessment.
3. The standard ACE-III assessment will then be administered by the clinician as part of routine care. No additional
appointments are required. At the GP site (Greenwich), Dr James Rogers will be trained in ACE-III administration for this study.
4. A subset of participants will be invited to take part in a qualitative interview, either in the form of an individual interview
or a focus group. These will be conducted by a qualitative PPIE expert from UCLP. Depending on the number of participants who opt in to participate. These will be delivered by either video call or in person, to explore their experience of using PuntoTest. They will be compensated £25 per hour for this additional optional qualitative component.

Number of Participants and Sites
- NHS participants: approximately 150 (spread across Oxleas Memory Service, Enfield Memory Service, Lewisham
Memory Service, and Greenwich GP Practice)

Patient and Public Involvement
A lived experience advisory panel were involved in the review of the protocol and patient consent materials, as part of a
series of PPIE workshops led by UCLPartners. Select members from this panel will also be invited to sit on the Steering Committee.

Co-design workshops will be held during study delivery to inform ongoing participant engagement and materials.
