INVENT 2025 Finalist: MemoryTell

Founders name: Corrina Grimes, Dr. Adolfo M. García and Fernando Johann


What was the “aha” moment that sparked your idea?

The “aha” moment came during conversations between Corrina and Adolfo as Senior Atlantic Fellows for Equity in Brain Health at the Global Brain Health Institute. Adolfo and Fernando were developing an AI algorithm, validated in research, that could detect subtle changes in speech linked to dementia. Corrina, with 25 years in the NHS and expertise in translating research into frontline services, immediately saw its potential to transform diagnosis pathways. Together, they recognised the opportunity to bridge cutting-edge science with clinical need.

Each founder also brought lived experience of dementia in their families. We understood the distress of delayed and inconsistent diagnosis — years of uncertainty, invasive and humiliating tests, and the reality that one in four patients wait over two years for a diagnosis, while one in three remain undiagnosed. This delay robs people of dignity, denies access to new treatments and trials, and places an enormous economic strain on families and health systems. Undiagnosed dementia triples the risk of A&E visits and can cost up to £80,500 per person annually in late-stage care. Globally, 57 million people were living with dementia in 2021, rising to 139 million by 2050, with costs escalating to $2.8 trillion by 2030.

We are solving the problem of late, costly, and inequitable dementia diagnosis. Current pathways are slow, subjective, and resource-heavy, leaving rural and underfunded services at a disadvantage. MemoryTell provides a fast, accurate, and scalable alternative that supports clinicians, saves costs, and offers families a dignified route to timely diagnosis and care. Whilst providing a solution for our health and social care systems.

What first impression do you want users to have when they experience/use your product?

Reassured by the simplicity of the test

Inspired by the opportunity to transform dementia diagnosis into a timely, dignified and scalable process

Confident the results are trustworthy, validated, and delivered with integrity and security


Where do you hope to be in five years?

In five years, we aim for MemoryTell to be a global standard for dementia diagnosis and monitoring, embedded across health systems in the UK, Europe, and beyond. We will have secured CE mark and FDA approval, enabling widespread clinical adoption. Our platform will be available in multiple languages, accessible in both high- and low-resource settings, and fully interoperable with digital health infrastructures.

By then, we expect MemoryTell to be used as routinely in primary care — empowering millions to receive earlier and more accurate diagnoses, reducing healthcare costs, and supporting research through richer real-world data.

Our vision is to deliver a timely, dignified, scalable and flexible solution that transforms dementia diagnosis worldwide, improves quality of life for patients and families, and supports governments, clinicians and researchers in tackling one of the greatest health challenges of our time.

What’s the best piece of feedback you’ve received so far?

Carers tell us that traditional pen-and-paper tests can feel humiliating and stressful, and welcome a dignified home-based alternative. Clinicians highlight the value of MemoryTell providing objective, unbiased data, with one stating it could “change the way we detect dementia — enabling more timely and accurate diagnosis.” Advocacy groups commend it for addressing a top priority: improving access to early, accurate dementia diagnosis. Health system leaders recognise its potential to reduce costs, free up capacity, and align with government strategies on dementia care.
