University of Grenada (UG) researchers have developed techniques that enable the early diagnosis of Alzheimer's disease by analyzing computer images.

The UG researchers, led by professor Ignacio Alvarez Illan, used SPECT and PET tomographies from three different databases to test the new system. The databases included brain CT scans from patients suffering from Alzheimer's disease or with normal development patterns.

The researchers developed a series of algorithms that can identify areas of the brain affected by the disease. The software had a 90 percent success rate in identifying the disease from PET and SPECT images. The researchers are now developing software to translate the results so they can be used in hospitals.
