Early detection and treatment of Alzheimer's disease require the use of dependable and cost-effective screening technologies. Researchers at Sweden's Karolinska Institutet have revealed that the level of tau, a protein that plays a vital role in the development of severe dementia, is associated with a kind of sugar molecule in the blood. The study, which is published in Alzheimer's & Dementia, can pave the way for a simple screening procedure able to predict onset ten years in advance. "The role of glycans, structures made up of sugar molecules, is a relatively unexplored field in dementia research," says the study's first author Robin Zhou, medical student and affiliated researcher at the Department of Neurobiology, Care Sciences and Society (NVS), Karolinska Institutet. "We demonstrate in our study that blood levels of glycans are altered early during the development of the disease. This could mean that we'll be able to predict the risk of Alzheimer's disease with only a blood test and a memory test." In Alzheimer's disease, the neurons of the brain die, which is thought to be a result of the abnormal accumulation of the proteins amyloid beta and tau. Clinical trials for Alzheimer's drugs show that treatment should commence early in the pathological process, before too many neurons have died, to reverse the process before it is too late.

An experimental Alzheimer's drug developed by Eli Lilly and Co slowed cognitive decline by 35% in a late-stage trial, the company said on Wednesday, providing what experts say is the strongest evidence yet that removing sticky amyloid plaques from the brain benefits patients with the fatal disease. Lilly's drug, donanemab, met all goals of the trial, the company said. It slowed progression of Alzheimer's by 35% compared to a placebo in 1,182 people with early-stage disease whose brains had deposits of two key Alzheimer's proteins, beta amyloid as well as intermediate levels of tau, a protein linked with disease progression and brain cell death. The study also evaluated the drug in 552 patients with high levels of tau and found that when both groups were combined, donanemab slowed progression by 29% based on a commonly used scale of dementia progression known as the Clinical Dementia Rating Scale (CDR-SB). Using that scale, experts said Lilly's findings were roughly on par with Eisai Co Ltd and Biogen Inc's lecanemab, sold under the brand name Leqembi, which reduced cognitive decline by 27% in patients with early Alzheimer's in a study published last year. The results drove Lilly's shares to a record high, up more than 6% at $429.85. Dr. Ronald Petersen, an Alzheimer's researcher at Mayo Clinic, said Lilly's trial is the third to show removing amyloid from the brain slows progression of the disease, which could put to rest some lingering doubts about the benefits of drugs in the class and the amyloid-lowering theory. "It's modest, but I think it's real," he said of the benefit, "and I think it's clinically meaningful." Dr. Erik Musiek, a Washington University neurologist at Barnes-Jewish Hospital, said the efficacy looks as good or better than lecanemab.

Diabetes drugs that also promote weight loss such as Novo Nordisk's Ozempic, becoming a darling of celebrities and investors, are being studied to tackle some of the most difficult-to-treat brain disorders, including Alzheimer's disease. Diabetes regimens, from Ozempic to old mainstays like insulin and metformin, appear to address several different aspects of the metabolic system implicated in Alzheimer's disease, including a protein called amyloid and inflammation, researchers say. The hope is that improving glucose utilisation and tamping down inflammation in the entire body - including the brain - could slow progression of debilitating diseases like Alzheimer's and Parkinson's. Several scientists interviewed by Reuters news agency pointed to mounting research supporting testing diabetes drugs against neurodegenerative diseases. Results are years away and success uncertain. But interest has been buoyed by recent positive data on Alzheimer's drugs developed by Eisai with partner Biogen and by Eli Lilly demonstrating that removing sticky amyloid plaques accumulated in the brain can slow cognition decline caused by the fatal mind-wasting disease. Those successes followed decades of futility that had left many questioning the validity of the amyloid theory behind most experimental Alzheimer's drugs.

The first big breakthrough in 30 years of Alzheimer's research is providing momentum for clinical trials of "cocktail" treatments targeting the two hallmark proteins associated with the mind-robbing disease, according to interviews with researchers and pharmaceutical executives. Drugmakers Eisai and Biogen reported in September that their therapy lecanemab could slow progress of the disease by 27% over 18 months compared with a placebo. The finding validates the theory that clearing the amyloid protein that forms clumps in the brains of Alzheimer's patients could slow or halt the disease and has strengthened the support from some scientists for simultaneously targeting another notorious protein linked to Alzheimer's: tau. Eisai and Biogen are scheduled to present full data from their lecanemab study on Tuesday at the Clinical Trials on Alzheimer's Disease conference in San Francisco. The U.S. Food and Drug Administration is expected to make a decision by early January on the companies' application for accelerated approval. If approved on an accelerated basis, the companies said they would immediately apply for full U.S. regulatory approval which could help secure Medicare coverage.

A £5m project has been launched to introduce new blood tests in the National Health Service (NHS) that can diagnose Alzheimer's disease. The blood tests could be available on the NHS within five years and they can diagnose the disease earlier and more accurately than current methods, experts have said. Alzheimer's Research UK, the Alzheimer's Society and the National Institute of Health and Care Research have jointly launched the project. Susan Kohlhaas, Executive Director of Research and Partnerships at Alzheimer's Research UK, said that the NHS doesn't possess the "required levels of diagnostic infrastructure" to cope with the "growing demand" for dementia diagnosis. "Low-cost tools like blood tests that are non-invasive and simpler to administer than current gold standard methods are the answer to this," she added.

According to Alzheimer's Disease International, more than 55 million people worldwide will have Alzheimer's disease by 2020. This figure will nearly double every 20 years, reaching 78 million in 2030 and 139 million in 2050. The WHO Global Status Report for 2021 estimated the yearly global cost of dementia to be more than USD 1.3 trillion, with a projected increase to USD 2.8 trillion by 2030. To date most drugs developed to treat Alzheimer's disease have failed, largely because they target wrong biomarkers and individuals already exhibiting signs of the disease. Once symptoms appear, however, many brain cells responsible for memory and cognition are likely already damaged and beyond repair. Professor Shai Rahimipour in the Chemistry Department at Bar-Ilan University in Israel has pioneered a different approach utilizing theranostics to pinpoint and treat the earliest, pre-symptomatic signs of Alzheimer's disease. Showing promise in stopping progression of the disease before onset of irreversible brain cell damage, Rahimipour's groundbreaking approach has garnered significant attention in the scientific world.

Alliance Healthcare UK team members Nick Atkins, Swansea Service Centre Manager, and Karl Goodall, Swansea Driver Team Manager, have climbed Pen y Fan in South Wales to support the Alzheimer's Society and raise money for dementia. The pair raised over £1,500, a cause close to Nick's heart, as his mother is a dementia patient. Dementia mainly affects people aged 65 and over, with 65 per cent of the 944,000 individuals living with dementia in the UK being women. Nick and Karl, dressed as 'glamorous grannies' with wigs, tights, and dresses, completed the mountain trek in six hours, carrying an Alliance Healthcare medicines cool box weighing over 35 kg. Alzheimer's Society supports people with dementia and their carers through national care and research efforts. Alzheimer's Society Cymru is the sole UK dementia charity funding both biomedical and care research.

Japanese pharmaceutical firm Eisai Co plans to seek full approval of its experimental Alzheimer's drug lecanemab in the United States, Europe and Japan armed with data showing it can slow the brain-wasting disease for people with early symptoms, potentially getting the treatment to patients next year. It remains unclear how widely the drug developed with U.S. biotech Biogen Inc will be used due to uncertainty over insurance coverage, including the U.S. government's Medicare plan for people age 65 and over, potential side effects and cost. One Wall Street analyst told Reuters news agency that he is not counting on measurable sales until 2024. Several estimated lecanemab may be priced at around $20,000 per year. "Most people who this (drug) would apply to are on Medicare, and most private payers look to Medicare as they make their own (coverage) decisions. So there's a massive roadblock in the way of all who could benefit from this treatment," said Robert Egge, Alzheimer's Association chief public policy officer. Eisai confirmed on Tuesday (November 30) that lecanemab - an antibody designed to remove sticky deposits of a protein called amyloid beta from the brain - reduced the rate of cognitive decline on a clinical dementia scale by 27% compared to a placebo. It also gave new details on side effects including a dangerous type of brain swelling and brain bleeding.

Japanese drugmaker Eisai said on Tuesday (January 10) it had submitted a marketing application to the European health regulator for review of its Alzheimer's drug lecanemab, which was recently granted accelerated approval in the United States. The drug, developed in partnership with Biogen, is an antibody that has been shown to remove sticky deposits of a protein called amyloid beta from the brains of those in the early stages of the mind-wasting disease. Nearly all previous experimental drugs using the same approach have failed. The company's application to the European Medicines Agency is based on results from a late-stage study in which the drug was shown to slow down the rate of cognitive decline in patients with early Alzheimer's by 27 per cent, compared with a placebo. Eisai also reiterated its plans to apply for marketing authorization of the drug in Japan by the end of its business year on March 31.

In a new study, men who took phosphodiesterase type 5 inhibitors (PDE5Is), such as Viagra (sildenafil; Pfizer), for treatment of erectile dysfunction, were found to be 18 per cent less likely to develop Alzheimer's compared to those who did not take the drugs. The results of the population-based cohort study were published in Neurology on 7 February 2024. Researchers at University of Oxford examined IQVIA Medical Research Data UK records of 269,725 men, who were diagnosed with erectile dysfunction between January 2000 and March 2017. None of the participants had any memory or thinking problems at the start of the study and they were followed for an average of 5.1 years. During the study, 749 out of 1,119 participants taking erectile dysfunction drugs developed Alzheimer's disease.

Soon doctors will look into your eyes to detect Alzheimer's disease! A new diagnostic tool has been developed by a Professor at University of Waterloo, Canada. The new tool, a non-invasive scan of eyes, has given hopes for detecting Alzheimer's years before the actual symptoms start appearing.

Alzheimer's is a mental illness that mostly affects the elderly. It is characterized by dementia, cognitive impairment, and mood swings. The patient gradually fades into a state of perpetual darkness and lack of self-awareness. Here are some steps we can take to reduce our own risk.

Scientists are trying to find ways to prevent Alzheimer's before it comes knocking at your doorstep. Extensive research is taking place even as you read this. Everyone hopes to put together the answer before it becomes a global issue. Here are a few risk factors that you can and can't avoid:

Digestive issues such as constipation, dysphagia and irritable bowel syndrome (IBS) may be precursors of Parkinson's disease, according to research published in the journal Gut. Gastrointestinal symptoms are thought to precede the development of some cerebrovascular disease, including brain aneurysm or Alzheimer's disease, and it has been suggested (Braak's hypothesis) that gut conditions may precede the development of Parkinson's disease too. To test this hypothesis, researchers used data from a US nationwide medical record network (TriNetX) to compare 24,624 people who had been diagnosed with Parkinson's disease of unknown cause with those who had been diagnosed with other neurological conditions - Alzheimer's disease (19,046) or cerebrovascular disease (23,942) - or with none of these (24,624; comparison group).

New research published in the medical journal Neurology suggests that high levels of cholesterol may increase a person's risk of developing Alzheimer's disease.
