Alzheimer's, the most common form of dementia, affects 5.3 million people in the United States, not to mention their families and close friends.
It targets the brain and causes memory loss and overall brain degeneration. Most common early symptoms can include short-term memory loss, problems with language, mood swings, and loss of motivation. However, there is no definitive technique to diagnose the disease until it's too late.
Currently, there is only one test that can determine if a person had Alzheimer's disease, and that test can only be conducted after the person has died.
"Current methods of diagnosing dementia can be slow and expensive, so finding a cheap, quick test that can accurately identify if someone has dementia is a top priority for researchers," said Doug Brown, director of research and development at Alzheimer's Society.
That's why this new test could prove to be so useful. But what kind of track record does this test have?
