Spanish scientists have created a new Alzheimer’s test app designed to detect early signs of the disease and other forms of dementia. Named The Mind Guardian, the app uses artificial intelligence and medical assessments to identify memory problems in individuals over the age of 55.
Developed by researchers from the University of Vigo, the Galicia Sur Health Research Institute, and Samsung, the app does not replace a doctor’s visit but serves as an initial screening tool.
The Mind Guardian features three interactive games that evaluate a user’s ability to recall events, complete daily tasks, and remember facts or words. Artificial intelligence analyses the results to identify potential memory decline. Tested and validated by Spanish neurology and psychiatry experts, the app has demonstrated a 97.1% accuracy rate in detecting early memory issues.
Technology with a purpose
Samsung contributed to the app’s development as part of a wider initiative to apply technology to social challenges. The Mind Guardian is now available for free in Spain for Android users and is recommended for individuals over 55.
Why early detection matters
Neurologist Carlos Spuch highlights the importance of early diagnosis: “Many people receive a diagnosis only when symptoms are severe, by which point treatment options are limited.” The app provides a quick cognitive assessment that traditionally takes two hours in a clinical setting but can now be completed at home in just 45 minutes.
Additionally, the app helps reduce the ‘white coat effect’, where individuals perform worse on cognitive tests due to anxiety in a medical setting. Furthermore, by presenting the test as a game, users feel more at ease, leading to more reliable results.
Origin of The Mind Guardian
The concept for The Mind Guardian originated in Vigo, where University of Vigo researchers had previously used video games to help older adults engage with technology. In 2014, Professor Luis Anido launched the Panoramix project, which used gaming to measure cognitive decline. Scientists now hope the new app will encourage users to take proactive steps for their brain health.
A healthy lifestyle supports brain function
If the app detects potential memory issues, users are advised to consult a doctor or retake the test in six months. Neurologists stress that maintaining a healthy lifestyle—including regular exercise, a balanced diet, and social engagement—can help slow cognitive decline.
With Spain’s life expectancy averaging 83 years, age-related memory problems are becoming more common. Currently, 1.4 million Spaniards rely on long-term care, with 60% suffering from cognitive decline. Each year, 40,000 people in Spain are diagnosed with Alzheimer’s, underscoring the need for early detection tools.
By providing an accessible way to monitor cognitive health, The Mind Guardian offers hope that individuals can take early action to preserve their mental well-being for as long as possible.
