British researchers have developed a revolutionary three-minute brainwave test that could detect Alzheimer’s disease years before symptoms appear.
Story Highlights
- New Fastball EEG test detects Alzheimer’s signs in just three minutes using passive brainwave monitoring
- Test works in patients’ homes without requiring verbal responses or complex cognitive tasks
- Technology could identify at-risk individuals years before traditional diagnosis methods
- NHS integration trials underway with large-scale US and UK validation studies enrolling 2,000 participants
Breakthrough Technology Offers Hope for Early Detection
Researchers at the University of Bath and University of Bristol have successfully developed the Fastball EEG test, which records electrical brain activity while patients view a series of images. The non-invasive procedure requires no active participation from patients, eliminating bias from education levels, language barriers, or anxiety that plague traditional cognitive assessments. Dr. George Stothart, the principal investigator, emphasizes that this technology can detect memory decline “far earlier and more objectively” than current diagnostic tools.

Home-Based Testing Revolutionizes Accessibility
The breakthrough extends beyond clinical settings, with successful trials demonstrating the test’s reliability in patients’ homes. This represents a significant advance over expensive biomarker tests and subjective cognitive assessments that often miss early changes. The home-based capability addresses a critical gap in healthcare accessibility, particularly for elderly patients who may struggle to reach specialized memory clinics. Results remained stable over one-year testing periods in both healthy older adults and those with Mild Cognitive Impairment.
Watch:
Commercial Development and Healthcare Integration
Cumulus Neuroscience Ltd. is developing AccelADx®, a scalable version of the Fastball technology for broader deployment across healthcare systems. Integration trials are currently underway in NHS memory clinics and GP surgeries, with plans for widespread rollout. The UK’s National Health Service faces significant challenges with up to one-third of dementia cases remaining undiagnosed, delaying crucial treatment and family support services.
Early Intervention Becomes Reality
The timing of this breakthrough aligns perfectly with advances in Alzheimer’s drug development, including treatments like donanemab and lecanemab, which show greatest effectiveness in early disease stages. Christopher Weber from the Alzheimer’s Association acknowledges the technology’s promise while noting the need for comprehensive diagnostic approaches including biomarkers and imaging. Current large-scale validation studies in both the UK and US are addressing these concerns by incorporating biomarker data for robust scientific assessment.
This innovation represents hope for millions of families facing the uncertainty of cognitive decline. The objective, accessible nature of Fastball EEG could fundamentally change how we approach Alzheimer’s screening, moving from reactive diagnosis to proactive early detection and intervention strategies.
