Researchers from the University of Bath and the University of Bristol have, for the first time, successfully tested Fastball EEG technology in patients\u2019 homes.<\/strong><\/p>\n

A noninvasive brainwave test created at the University of Bath has proven capable of detecting early signs of memory decline associated with Alzheimer\u2019s disease long before conventional diagnosis is usually possible.<\/p>\n

Details of the research, published in Brain Communications by scientists from the University of Bath and the University of Bristol, show that the Fastball EEG test can reliably spot memory difficulties in individuals with Mild Cognitive Impairment (MCI), a condition that often precedes Alzheimer\u2019s. The test takes just three minutes, passively recording brain activity while participants view a rapid sequence of images. This work builds on a 2021 study<\/a> in which the same team first showed the method\u2019s sensitivity to memory impairment caused by Alzheimer\u2019s.<\/p>\n

\nExpanding access beyond clinics<\/p>\n

For the first time, the researchers also demonstrated that the Fastball EEG can be carried out successfully in people\u2019s homes, removing the need for a clinical setting. According to the team, this advancement paves the way for broader screening and ongoing monitoring with affordable, easy-to-use technology.<\/p>\n

The development of Alzheimer\u2019s drugs such as donanemab and lecanemab makes early detection even more critical, as these treatments are most effective during the disease\u2019s initial stages. Yet in England, estimates suggest that around one in three people with dementia remain undiagnosed, which delays not only treatment but also access to support and research opportunities aimed at addressing the condition.<\/p>\n

The study was led by Dr. George Stothart, a cognitive neuroscientist in the Department of Psychology at the University of Bath. He said:<\/p>\n

\u201cWe\u2019re missing the first 10 to 20 years of Alzheimer\u2019s with current diagnostic tools. Fastball offers a way to change that \u2013 detecting memory decline far earlier and more objectively, using a quick and passive test.\u201d<\/p>\n

\nHow the test works<\/p>\n

Fastball is a passive EEG test that monitors the brain\u2019s automatic responses to images \u2013 without requiring participants to follow instructions or recall information. This makes it more objective and accessible than traditional memory tests.<\/p>\n

Researchers say Fastball could be scaled for use in GP surgeries, memory clinics, or at home \u2013 helping deliver earlier, more accurate diagnoses.<\/p>\n

Dr. Stothart added, \u201cThere\u2019s an urgent need for accurate, practical tools to diagnose Alzheimer\u2019s at scale. Fastball is cheap, portable, and works in real-world settings.\u201d<\/p>\n

Chris Wiliams, CEO of BRACE Dementia Research, said: \u201cFastball is an incredible tool that could offer anyone who, for whatever reason, cannot access a dementia diagnosis in a clinical setting. BRACE has been supporting the development of Fastball for several years, and we are excited to see what Dr. Stothart\u2019s team will achieve over the next few years with ongoing support from the charity.\u201d<\/p>\n
