People who’ve been diagnosed with Alzheimer’s disease don’t have decades to wait for a cure. They need help now. Many would be willing to use a drug that is still in clinical trials with the hope of experiencing positive results. There’s a second reason to enroll in clinical trials, however. Even if the results of a trial aren’t what they wished for, participants can feel satisfied that they’ve taken part in adding to the body of knowledge that will one day conquer Alzheimer’s.
