Early Alzheimer’s signs detected in 3 minutes with new brainwave test

Fastball EEG test detects memory decline linked to Alzheimer’s years before diagnosis, showing reliable results in a trial of 106 participants, aiding early intervention efforts.

  • Scientists at the Universities of Bristol and Bath have created a three-minute brainwave assessment called Fastball to identify early memory impairments associated with Alzheimer's disease.
  • The test emerged because current diagnostic tools miss the first 10 to 20 years of Alzheimer's, delaying early and accurate diagnosis needed for timely intervention.
  • In a study of 106 participants, individuals with amnestic mild cognitive impairment demonstrated notably lower EEG signal responses relative to healthy older adults, and the testing method was successfully implemented in non-clinical environments, including participants’ homes.
  • Dr George Stothart highlighted that existing diagnostic methods fail to detect Alzheimer's during its initial decade or two, while Chris Williams praised Fastball as a remarkable solution for enabling dementia diagnosis in individuals who may lack access to traditional clinical assessments.
  • While Fastball cannot yet classify individuals or predict disease progression, larger trials and long-term studies are underway to validate its clinical utility and potential for wider screening.
