The most in-depth analysis of human brain tissue ever done in Alzheimer's disease has found evidence for the controversial theory that viruses play a role in the condition. If true, it could mean that some instances of Alzheimer's might be treated with anti-viral drugs. Alzheimer's is the most common cause of dementia, affecting some 47 million people worldwide.
One of Pam Montana's most profound moments in her two-year journey with Alzheimer's disease occurred when her doctor ran through a list of must-dos. Eat well, exercise and learn a new language, the doctor said. "She said, 'Do what makes you happy,' " said Montana, 63, who has younger-onset Alzheimer's. The former tech executive now lives by that mantra, especially when it comes to travel. "I have given myself permission to do whatever I need to do, whenever I need to do it," she said.
Out of the total number, 48 were scans of people with the disease, while 48 were scans of people who suffered from mild cognitive impairment and eventually developed full-blown Alzheimer's. The AI was able to diagnose Alzheimer's 86 percent of the time. More importantly, it was able to detect mild cognitive impairment 84 percent of the time, making it a potentially effective tool for early diagnosis. With more samples and further development, though, the AI could become more accurate until it's reliable enough to be used as a non-invasive early detection system.
