Breakthrough Three-Minute Brainwave Test for Early Alzheimer’s Detection

Researchers at the University of Bath and the University of Bristol have developed a groundbreaking three-minute brainwave test, known as the Fastball test, which can identify memory issues linked to Alzheimer’s disease significantly earlier than traditional diagnostic methods. This non-invasive test utilizes electroencephalography (EEG) to measure brain activity while participants view a rapid sequence of images. The study involved 54 healthy adults and 52 patients diagnosed with mild cognitive impairment (MCI), a condition that can lead to Alzheimer’s.

During the Fastball test, small sensors placed on the scalp record the brain's automatic responses to images displayed on a screen. Participants are shown a series of images, including some they had seen previously, without being instructed to memorize them. The results indicated that individuals with amnestic MCI, characterized by significant memory loss, exhibited weaker brain responses compared to healthy individuals and those with non-amnestic MCI. This suggests that the test may effectively flag those at higher risk of developing Alzheimer’s.

The Fastball test holds promise for earlier intervention with emerging Alzheimer’s treatments, such as donanemab and lecanemab, which are most effective in the disease's early stages. Dr. George Stothart, the lead researcher, emphasized that current diagnostic tools often miss the earliest stages of Alzheimer’s, sometimes by decades. He stated, “Fastball offers a non-invasive, objective way to detect memory decline much earlier, which could help identify those who might benefit most from emerging treatments.”

Conducted in participants' homes, the Fastball test aims to enhance accessibility and reduce anxiety associated with clinical environments. Experts, including Prof. Vladimir Litvak from UCL’s Queen Square Institute of Neurology, view this research as a promising initial step toward developing a clinically viable testing method. However, they stress the need for larger, longer-term studies to confirm the test's predictive capabilities and to explore how it may complement other diagnostic tools, such as cognitive assessments and blood tests.

While the Fastball test shows potential, experts caution that it cannot definitively predict who will develop Alzheimer’s. Dr. Julia Dudley from Alzheimer’s Research UK noted the necessity for long-term studies across diverse populations to ascertain the test's effectiveness. She remarked, “This study suggests that it can be used to measure mild memory impairment, which for some people can be an early sign of diseases like Alzheimer’s. However, we don’t know if those people will definitely go on to develop dementia.”

The research team is currently conducting larger trials to validate the test’s effectiveness across diverse populations and over extended periods. These studies will also investigate how various health conditions might influence results and how the Fastball test could integrate with existing diagnostic methods. As the number of individuals living with dementia is projected to rise significantly, tools like Fastball could pave the way for earlier, more equitable access to diagnosis and treatment, offering hope to millions at risk.

• “Early detection is critical for new treatments to be effective. This study shows promise, but larger, longer-term studies are needed to confirm whether the test can predict the progression of memory issues and how it might complement other diagnostic tools like cognitive assessments or blood tests.” — Dr. Julia Dudley, Alzheimer’s Research UK
