Using new computer software that analyzes EEG data, doctors can now better distinguish early signs of Alzheimer's from normal aging, by spotting marked differences between the left and right sides of the brain. Diagnosing Alzheimer's early can be vital because new drugs can now slow the progression the disease. The new technique is cheaper and less invasive than using MRIs or PET scans for the same diagnosis.
