Insights into Amyloid Natural State Suggest New Course of Alzheimer’s Treatment
With the help of an extremely powerful infrared spectroscopy method, researchers have found evidence challenging the widely held theory that Alzheimer’s disease can be prevented by clearing amyloid-beta from the brain. The research team at Lund University in Sweden discovered that amyloid-beta naturally exists as a four-unit complex and not as a single peptide (a shorter protein) as researchers believe. This suggests that it may be the separation of the complex's smaller pieces that makes amyloid aggregate. Therefore, the team suggests that it may be possible to treat Alzheimer’s by using drugs that stabilize the amyloid complex. Such a drug is already approved for a disease caused by the breaking up of a four-unit amyloid-complex. The study, “Pre-plaque conformational changes in Alzheimer’s disease-linked Aβ and APP,” was published in the journal Nature Communications. "No one has used this method to look at Alzheimer's development before. The images tell us that the progression is slower than we thought and that there are steps in the development of Alzheimer's disease that we know little about. This, of course, sparked our curiosity," Gunnar Gouras, professor in experimental neurology at Lund University and senior author of the study, said in a press release. Today, the scientific community is dominated by a number of ideas. Many researchers are convinced that Alzheimer’s disease is linked to the development of amyloid-beta plaque — which has led to numerous cli

    I have early stage Alzheimer’s. It runs on my maternal side. My aunt, my Mom my Aunts daughter and my sister. All are deceased. My sister was 12 years older than I.
    Being extremely concerned that I may get the disease, I saw a number of neurologists in NYC. I live in Burlington VT.
    To cut a long story short, I have been on Aricept 10mg for several years. I also suffer from depression and have been on a cocktail of drugs for many many years.

    I am 67 and in good health except for short term memory problems. I live alone with my 3 cats in Burlington VT.

    I would be very appreciative if you could send me detailed information. I will do anything to stop this disease in its tracks. I hope to hear from you.

      Dear Linda,
      Thank you for sharing your story. We at Alzheimer’s News Today are truly sorry to hear that you are anticipating the disease.
      The best way to keep updated is to sign up for our newsletter, where we frequently include information about clinical trials. many trials now focus on patients who do not yet have diagnosed Alzheimer’s disease, but are at risk of developing the illness.

    The article references a drug already approved for other purposes may be helpful to AD patients by breaking up the amyloid complex. The article does not mention the name of this approved drug. My wife was in the Merck clinical trial of MK8931 for 4 years. Merck recently “pulled the plug on the trial because it became clear that the drug had little chance of approval. Some believe the trial was targeting the wrong profile. My wife stabalized trememdously during the trial, therefore I am convinced that the drug did help her. Now I am searching for a new trial (thru Trial Match) or a new treatment. It seems to me that we are on the cutting edge of finding help but time is not on Marilyn’s side. Also FYI, she has been on elevated doses of Airicept and Namenda for many years.
    Any insight for a direction would be appreciated.
