(Newser) – Researchers say they've found another possible way to detect Alzheimer's, this time through a blood test that looks for antibodies. Though still under development, a diagnostic kit could be available within the year, reports Reuters. The catch: While scientists are getting better at detecting Alzheimer's with such discoveries, they still can't cure the disease.

"It's unclear whether people would want to know a couple of years ahead of time they are going to get Alzheimer's if they can't do anything about it," says a scientist with the Scripps Research Institute. "But I can say with some certainty that we will never get a good therapy for Alzheimer's without early diagnosis." More details here on the science involved in the blood test, which could theoretically work on other diseases such as cancer.
