The topline results for the Anti-Amyloid treatment in Asymptomatic Alzheimer’s disease (A4) study were released today (https://a4study.org). Unfortunately, the drug being investigated, solanezumab, failed to demonstrate a benefit in slowing memory changes in a population of individuals age 65-to-85 who met criteria for preclinical Alzheimer’s disease. Preclinical Alzheimer’s is a relatively new construct. It includes people who are older and have normal memory performance, but in whom biological tests suggest that the risk for Alzheimer’s disease dementia is high. The A4 study was among the first ever preclinical AD trials, boldly blazing a trail that has now been followed by…

On February 17, 2023, a bipartisan group of Senators sent the Secretary of Health and Human Services, Javier Baccera, and the Administrator of the Centers for Medicare and Medicaid Services (CMS), Chiquita Brooks-LaSure, a letter requesting that CMS reconsider their decision to require Coverage with Evidence Determination (CED) that was levied after the accelerated approval of aducanumab. The letter followed a similar request from the Alzheimer’s Association, made in December 2022. The CED decision significantly limited access to aducanumab and other monoclonal antibodies (should they be approved), requiring that coverage would be granted only if Medicare beneficiaries were enrolled in…

Frontotemporal dementia (FTD) is a form of dementia that typically affects individuals in their 50s and 60s. It is therefore, commonly referred to as young onset dementia. Clinically, FTD can present in two ways; some patients present with behavioral impairment and are referred to as behavioral variant FTD (bvFTD). The other main presentation involves language decline and is called primary progressive aphasia (PPA). Both conditions start insidiously and accurate diagnosis can be a challenge, especially at early stages of the disease. In bvFTD, patients can present with apathy, lack of empathy, increased appetite, preference for sweet tooth, new onset of…

In a somewhat surprising move, the US Food and Drug Administration (FDA) has declined to grant accelerated approval to Eli Lilly’s donanemab Read the full press release from Eli Lilly here Like aducanumab and lecanemab, which were previously granted accelerated approval by the FDA, donanemab is a monoclonal antibody treatment against the beta amyloid protein that accumulates in the brain of a person with Alzheimer’s disease. Eli Lilly published very promising results for donanemab in 2021, which included demonstration that donanemab could lower amyloid levels in the brain of people with mild cognitive impairment and mild dementia (the basis for…

January 6, 2023 – Today, as expected, the US Food and Drug Administration granted accelerated approval to lecanemab, a monoclonal antibody against the beta amyloid protein that accumulates in the brain of people with Alzheimer’s disease. Lecanemab was approved on the basis of the treatment’s demonstrated effect of lowering levels of brain amyloid, as measured by a type of brain scan known as positron emission tomography (PET) imaging. Lecanemab is now approved for the treatment of patients with mild cognitive impairment or mild dementia, and should be used in patients in whom that same amyloid PET brain scan (or measures...

Eat This, Not That! “According to a study performed by UCI MIND and presented at the American Association for the Advancement of Science, there’s a connection between longevity and drinking a moderate amount of alcohol. (Let’s stress the “moderate.”) The research involved individuals 90+ years of age. In this particular study, participants who drank approximately two glasses of wine or beer were linked to an 18% decreased risk of early mortality. So sipping in moderation can be a good thing!” Learn more here >  Learn about The 90+ Study here >

When the U.S. Food and Drug Administration gave controversial accelerated approval to the first Alzheimer’s drug in nearly 20 years, it had a surprising impact on attitudes about research into the disease. A survey by University of California, Irvine neuroscientists has found news coverage of the FDA’s decision made the public less willing to volunteer for Alzheimer’s pharmaceutical trials. The study was conducted by the UCI Institute for Memory Impairments and Neurological Disorders, known as UCI MIND. It appears in the Journal of Alzheimer’s Disease. (Link to abstract) The UCI team performed the survey in tandem with the FDA’s spring…

Healthline – “There is a lot of evidence that links sleep apnea to Alzheimer’s disease risk,” added Bryce Mander, Ph.D, assistant professor, Psychiatry & Human Behavior, School of Medicine at the University of California, Irvine. “But there is limited data on the beneficial effects of sleep apnea treatment on risk for dementia.” He continued: “This study offers proof of concept evidence that treating sleep apnea may reduce Alzheimer’s disease risk. [It] also offers potential novel molecular targets for future study for those where positive airway pressure treatment is not feasible.” Read more here >

Eat This, Not That! – Nov. 1, 2022 ‘An increase in dementia cases is alarming, especially since there’s no cure and Dr. Michael Yassa, neurobiologist and director of the Center for the Neurobiology of Learning and Memory at the University of California, Irvine shares why there’s an uptick. “Remember that the biggest risk factor is age, and we are an aging population. Advances in medical care have managed to extend our lifespan beyond anything we could have ever imagined a hundred or two hundred years ago. So the prevalence of dementia is increasing because we have more and more people…

University of California, Irvine Chancellor Howard Gillman states: “Our faculty continues to do a tremendous job of winning research grants, the lifeblood of our research efforts. In just the last couple of months…our renowned Institute for Memory Impairments and Neurological Disorders, known as UCI MIND, received a grant of $47 million from the National Institute on Aging; an interdisciplinary UCI team will receive $10 million from the National Institutes of Health…Clearly, the future of science at UCI is very bright indeed.”  

Responding to an article written in AlzForum on the future of Alzheimer’s treatment and research from October 7th, Joshua Grill, PhD, from UCI MIND, and his colleague, Jason Karlawish, MD, from the University of Pennsylvania, write: “Anticipation that FDA will grant full approval of lecanemab (or another disease-modifying treatment) invites an exciting but challenging thought exercise: How will such treatments change research and practice for Alzheimer’s disease (AD)? We’ve considered some of the issues. Our top line point is that a new disease-slowing treatment is unlikely to make use of placebo controls immediately and categorically unethical (Grill and Karlawish, 2021)….
