A University of Minnesota scientist has found a way to detect Alzheimer's disease, schizophrenia and other brain disorders by using a device that tracks magnetic signals in the brain.
The research is still in its early stages, but experts say it could lead to a relatively quick and painless test for a wide range of conditions that affect the brain.
Scientist Apostolos Georgopoulos calls his discovery an "elegantly simple test" that has been surprisingly accurate so far in assessing nearly 300 patients and healthy volunteers.
His research team identified six types of disorders using technology known as MEG to study people's brains as they stared at a point of light for 45 to 60 seconds.
