Currently, there are no treatments that address the root causes of the neurodegenerative condition, which include the build up of amyloid plaques in the brain and the formation of tau tangles once nerve cells start to die off. One drug, from Eli Lilly, aims to soak up amyloid and thus prevent it from accumulating in the damaging plaques that suffocate neurons in the brain. But to test its effectiveness in a timely manner, the scientists adopted an unorthodox trial design — they divided participants with mild to moderate disease into two groups, one that took the drug, which is given via IV, and another that took placebo. After 18 months, there were no significant differences between the groups on cognitive tests, although people with mild disease seemed to show signs of improvement. So those on placebo were then switched to the study drug, called solanezumab, and followed for another 18 months to two years. The idea was that by the end of the study, the participants who had been taking the drug all along should show greater improvements in cognitive skills than those who switched midway through. **MORE:** [Alzheimer’s May Show Up in Saliva](http://time.com/3963430/alzheimers-test-saliva/) That’s what the researchers saw. In their report, they said that the two groups showed differences in their thinking abilities. But whether that gap can be attributed to the drug alone isn’t entirely clear—at least not yet. And whether that difference is enough to fuel further study, especially in people at the earliest stages of the disease, or form the basis of an approval by the Food and Drug Administration is even more uncertain. **MORE:** [Your School Grades Affect Your Risk of Dementia](http://time.com/3963421/school-grades-dementia/) The other experimental agent, aducanumab, also sops up amyloid, but was associated with brain swelling in earlier studies at higher doses. Scientists at Biogen, which is developing the compound, added an intermediate dose to get a better sense of how much of the drug could produce the most benefit without triggering side effects. The results were from an earlier stage of testing, and focused primarily on safety of these doses so developers could not say for certain whether the improvements they began to see in slowing cognitive decline were significant. But they were enough to warrant more study. Both trials show that, while promising, the first-ever treatments for Alzheimer’s have a ways to go still on this long, and often precarious road. ## Transcript You're watching everwell. Know more. Live better. [ MUSIC ] I enjoy playing Scrabble from time to time. It keeps me thinking about words and it's fun. I do the Sunday crossword puzzle every week, to keep my mind active. It is an idea that's really caught on, that exercising your brain regularly, with puzzles for example, can keep your mind sharp, and ward off dementia and Alzheimer's disease. And it's become big business. Today you can find video games, DVDs and special software that promise to keep you mentally fit. There are also subscription websites which charge about $ 100 a year for an array of brain boosting games. In a way it makes sense. Just as physical activity can keep your body strong, mental exercise can keep your brain in shape. But is it really true? Studies show that brain training can help improve your memory. But that's different from warding off dementia. And people who do stimulating activities like reading, learning a new language, or playing a musical instrument have lower rates of dementia and Alzheimer's but this doesn't necessarily prove cause and effect. [ MUSIC ] So the bottom line, the jury is still out. Still it's a good idea to keep your mind active, but you don't need to spend a lot on special products. Anything from crossword puzzles to challenging board games can do the trick. Perhaps the best thing for your brain is regular physical activity. Research shows it can help improve older people's ability to remember and process information more quickly. [ NOISE ] So next time you forget where you parked your car, don't sweat it. Just use it as an opportunity to go for a walk. Your brain will thank you. Helping you be a healthy skeptic, I'm Robert Davis. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3967541/new-alzheimers-drugs/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3967541/new-alzheimers-drugs/"},"headline":"Two New Alzheimer’s Drugs Offer Hope—With Caveats","datePublished":"2015-07-22T15:15:01.000Z","dateModified":"2026-08-04T07:58:27.601Z","description":"Reports on two compounds provide limited optimism in the search for pharmaceutical answers to treating Alzheimer’s disease","url":"https://time.com/3967541/new-alzheimers-drugs/","keywords":["Brain","Alzheimer's","amyloid"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt74eeb944d2dc4c17/69885bed35ba6f454bc0e4ab/alzheimers.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt74eeb944d2dc4c17/69885bed35ba6f454bc0e4ab/alzheimers.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Missing jigsaw piece in head","caption":"Missing jigsaw piece in head","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/brain/","name":"Brain"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3967541/new-alzheimers-drugs/","name":"Two New Alzheimer’s Drugs Offer Hope—With Caveats"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Do Brain Exercises Really Keep You Mentally Fit?","description":"Do Brain Exercises Really Keep You Mentally Fit?","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/t67dFcgw/poster.jpg?width=720","uploadDate":"2015-05-15T21:17:02.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/t67dFcgw.m3u8","embedUrl":"https://time.com/3967541/new-alzheimers-drugs/","duration":"PT2M3S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3967541/new-alzheimers-drugs/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
