"A three-minute test can detect signs of concerning memory problems linked to Alzheimer's disease years before doctors typically diagnose the condition. Fastball, an inexpensive tool that scans a patient's brainwaves, showed for the first time that this type of test could be conducted at home and could reliably reveal signs of mild cognitive impairment (MCI), a condition that sometimes leads to Alzheimer's."
"The study found that people with amnestic MCI had much weaker brain responses on the Fastball test compared to healthy adults and those with non-amnestic MCI. Researchers said that Fastball is a promising, simple, and non-invasive way to check memory in people with early signs of MCI without a doctor or specialist. In the US, approximately 7.2 million people over the age of 65 are living with Alzheimer's disease, the most common form of dementia."
The Fastball approach uses an inexpensive EEG cap and a three-minute visual task to elicit automatic brain responses that differ between amnestic MCI, non-amnestic MCI, and healthy older adults. Amnestic MCI produced much weaker Fastball brain responses than other groups, enabling reliable detection in a clinical trial involving 53 MCI patients and 54 healthy adults. Participants were classified by memory test scores and completed a rapid picture-viewing task while wearing the EEG cap. The method is simple, non-invasive, and adaptable for at-home screening, facilitating earlier identification of memory impairment that can precede Alzheimer's by a decade or more.
