A simple chat with your doctor could soon be enough to spot the early warning signs of dementia.
MemoryTell, an Irish startup, has built a powerful tool that uses artificial intelligence to analyze voice patterns for signs of cognitive decline. This technology offers a fast and painless alternative to the stressful memory tests and invasive procedures currently used in clinics.
How voice patterns act as a warning for brain health
Dementia cases are rising at an alarming rate across the globe.
Ireland alone has over 64,000 people living with the condition today. Experts predict this number will more than double by the year 2045 as the population ages.
Doctors currently rely on a mix of pen and paper tests, family interviews, and expensive scans to form a diagnosis.
MemoryTell changes the game by treating the human voice as a rich source of medical data.
The platform listens to a patient speaking and hunts for “biomarkers” that are invisible to the human ear.
It is not just about what words a person says.

“It analyzes patterns in language, rhythm, pauses, and acoustics that research shows can signal cognitive decline,” the team explained.
The AI compares these speech samples against a massive database.
This database contains over 13,000 clinically coded records from both healthy volunteers and patients with confirmed conditions.
By spotting subtle changes in speech flow or word choice, the tool provides an objective score.
This removes the guesswork and subjectivity often found in standard memory quizzes.
It allows clinicians to see a “red flag” long before physical symptoms might become obvious to family members.
Here is a breakdown of what the AI actually listens for during the assessment:
- Acoustic Features: It measures the length of pauses, the speed of speech, tone, and silence duration.
- Linguistic Features: It checks for vocabulary variety, complex sentence structures, and how often a person stumbles over words.
- Rhythm: It analyzes the prosody, which is the musicality and stress used in normal conversation.
Meeting of minds creates a powerful medical tool
This innovation did not happen in a vacuum.
It was born from a collaboration between a clinician, a neuroscientist, and a tech entrepreneur.
Corrina Grimes brings 25 years of experience in health and social care policy.
She teamed up with Adolfo García, a neuroscientist with over 200 publications to his name. García had already developed a toolkit called TELL to examine life-like language in a lab setting.
They needed someone to help scale this science into a real-world product.
Fernando Johann, an engineer with a history of successful business exits, joined as the third co-founder.
Together, they aim to move this technology from research papers directly to the front lines of patient care.
The team met through the Global Brain Health Institute. This is a prestigious program affiliated with Trinity College Dublin and UCSF in San Francisco.
Their diverse backgrounds allow them to tackle the problem from every angle.
Grimes understands how health systems work, García understands the brain, and Johann understands how to build scalable software.
Making the diagnosis process faster for local doctors
One of the biggest hurdles in dementia care is the waiting game.
Patients often wait months to see a specialist after visiting their General Practitioner (GP).
MemoryTell is designed to slot perfectly into a standard 10 minute primary care appointment.
The process is simple and requires no special equipment other than a device to record audio.
A patient engages in a brief recorded conversation or describes a picture.
The audio is processed instantly in the cloud.
Within moments, the doctor receives a detailed PDF report on their screen.
This report indicates the likelihood of cognitive impairment based on the speech analysis.
It does not replace the doctor but acts as a powerful second opinion to support their decision.
This speed is vital for early intervention.
When doctors catch dementia early, they can plan better care pathways for the patient and their family.
Current methods often leave patients in limbo.
Table: Current Standard Care vs. MemoryTell Approach
| Feature | Standard Diagnosis Path | MemoryTell Approach |
|---|---|---|
| Time Required | Hours to days of testing | 10 minutes |
| Invasiveness | High (Lumbar punctures, bloods) | Zero (Just speaking) |
| Results | Weeks or months | Instant real-time report |
| Objectivity | Subjective (varies by doctor) | 100% Data-driven |
| Cost | High (Specialist clinics) | Low (Primary care level) |
This tool also allows for longitudinal tracking.
Doctors can record a patient every six months to see if their condition is stable or declining.
This is something that is currently very difficult to do with standard one-off memory tests.
Big win fuels the path to public health services
The startup has already gained massive traction in the medical and business communities.
In October 2024, MemoryTell secured a major victory at the Catalyst Invent Awards.
They took home the top prize in the Bio-Breakthrough category and won the overall competition.
This win has put a spotlight on their mission and attracted serious attention from investors.
However, the team is not just looking for quick profit.
Grimes has stated that their primary mission is rooted in public services rather than just private clinics.
“I have 25 years’ experience working across health systems, so I understand the implementation challenges from inside the system,” Grimes noted.
They are currently running validation studies to prove the tool works in busy clinic environments.
The goal is to secure CE marking, which is the regulatory approval needed to sell medical devices in Europe.
Once approved, they plan to roll this out to GPs and memory clinics across the continent.
This could significantly cut down waiting lists and free up specialists to treat the most complex cases.
It is a tool born in Ireland that has the potential to help millions of families worldwide.
With the population aging rapidly, innovations like this are no longer just “nice to have.”
They are essential tools for a healthcare system under pressure.
MemoryTell is turning the simple act of speaking into a lifesaver.
By listening to what we say and how we say it, AI is giving doctors a head start in the fight against dementia. This technology brings dignity to the patient and clarity to the clinician. It transforms a scary, uncertain process into a manageable, data-backed plan of action.
