We now have more accurate ways of diagnosing Alzheimer’s and are moving closer to developing drugs to directly attack the disease. Much of this work is still in the early stages, but experts are growing more hopeful about dealing with the debilitating disease, which currently has no cure.
Proposed preclinical stages for Alzheimer’s disease work well to predict who is most likely to progress to AD, according to a paper released online by Lancet Neurology.
Researchers led by Stephanie Vos and Pieter Jelle Visser at Maastricht University in the Netherlands and Anne Fagan and others at Washington University in St. Louis, Missouri, analyzed data from 311 cognitively normal elderly people seen at St. Louis’s Knight Alzheimer’s Disease Research Center.
Paul Aisen, MD, Director of the ADCS, expands on the significance of the ADCS DAPC independent analysis of the semagacestat trial which was published last week in the New England Journal of Medicine.
A team of scientists, including Paul Aisen, MD, professor of neuroscience and director of the Alzheimer’s Disease Cooperative Study, issued a sort of post-mortem on semagacestat, a small-molecule gamma-secretase inhibitor that drug developer Eli Lilly hoped would prove to be an effective treatment for Alzheimer’s disease (AD).
Additional data from the Phase III Gammaglobulin Alzheimer’s Partnership (GAP) study, including select analyses of subgroups, biomarker and imaging data, was presented at the Alzheimer’s Association International Conference (AAIC) in Boston, Massachusetts
On cognitive measures, an analysis of ApoE4 carrier patients who were treated with the 400mg/kg biweekly dose (n=87) of immunoglobulin (IG), found a statistically significant difference (p=0.012) in change from baseline in the 3MS score at 18 months versus placebo.
When a neuron gets blocked, the delicate harmony that allows the brain to operate seamlessly deteriorates. One result: diseases like Alzheimer’s. Understanding such blockages and how “traffic” should flow normally in healthy brain cells could offer hope to people with neurodegenerative diseases.
Toward that end, a research team led by University at Buffalo biologist Shermali Gunawardena, PhD, has shown that the protein presenilin plays an important role in controlling neuronal traffic on microtubule highways, a novel function that previously was unknown.
U.S. HHS released the National Plan to Address Alzheimer’s Disease: 2013 Update. The 2013 Update includes a new timeline for achieving its first goal – prevent and effectively treat Alzheimer’s disease by 2025 – and a review of progress over the past year.
The first-ever National Alzheimer’s Plan, initially released in May 2012, was mandated by the bipartisan National Alzheimer’s Project Act (P.L. 111-375), which Congress passed unanimously in 2010. The 2013 Update includes a new timeline for achieving its first goal – prevent and effectively treat Alzheimer’s disease by 2025 – and a review of progress over…
By Paul Aisen, M.D. Director, Alzheimer’s Disease Cooperative Study Professor of Neurosciences, University of California San Diego There has been much discussion in the news lately as to whether the amyloid hypothesis is the correct path for research. The amyloid hypothesis is supported by a huge body of evidence, but to my thinking the most…
