A preliminary study has found that when young, healthy men were deprived of just one night of sleep, they had higher levels of tau, a biomarker for Alzheimer’s disease, in their blood than when they had a full, uninterrupted night of rest. The study is published in the January 8, 2020, online issue of Neurology, the medical journal of the American Academy of Neurology. Tau is a protein found in…
Brain imaging of pathological tau-protein “tangles” reliably predicts the location of future brain atrophy in Alzheimer’s patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid “plaques,” which have been the focus of Alzheimer’s research and drug development for decades, was found…
Crucial early diagnosis of dementia in general practice could improve thanks to a computer model designed in a collaboration between Brighton and Sussex Medical School (BSMS) and astrophysicists at the University of Sussex. Currently, only two-thirds of people with dementia in the UK receive a formal diagnosis, and many receive it late in the disease process, meaning that a large number are…
Inflammation drives the progression of neurodegenerative brain diseases and plays a major role in the accumulation of tau proteins within neurons. An international research team led by the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn comes to this conclusion in the journal “Nature”. The findings are based on the analyses of human brain tissue and further lab…
Researchers have created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders.
Viscosity sensors are used by scientists fighting various diseases, such as Alzheimer's and Diabetes. Vilnius-based chemist Aurimas Vyšniauskas has enhanced their measuring capabilities. This breakthrough will equip researchers with additional tools to study living cells and how they change in a sick organism.
Biologists from the University of California, Irvine have made a major finding on combating inflammation linked to Alzheimer's disease. The School of Biological Sciences researchers’ discovery about the role of a protein called TOM-1 heralds a shift toward examining the molecular underpinnings of Alzheimer’s processes. Their study appears online in Proceedings of the National Academy of…
More and more people aged 50 and over are suffering from age-related vision disorders. According to the World Health Organization, in four out of five cases they could be avoided if they were diagnosed at an early stage. A European team of scientists, including the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has now researched a new method that will enable doctors to better…
Think twice before adding that extra kick of chili sauce or chopped jalapeno to your meal. New research involving the University of South Australia shows a spicy diet could be linked to dementia. A 15-year study of 4582 Chinese adults aged over 55 found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. Memory decline was even more significant if…
Virtual reality (VR) can identify early Alzheimer’s disease more accurately than ‘gold standard’ cognitive tests currently in use, suggests new research from the University of Cambridge. The study highlights the potential of new technologies to help diagnose and monitor conditions such as Alzheimer’s disease, which affects more than 525,000 people in the UK. In 2014, Professor John…
A recently recognized brain disorder that mimics clinical features of Alzheimer’s disease has for the first time been defined with recommended diagnostic criteria and other guidelines for advancing and catalyzing future research. Scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly-named pathway to dementia,…
A protein complex has been shown to play a key role in preventing the build-up of toxic plaques in the brain linked to neurodegenerative disorders such as Alzheimer’s and Huntington’s disease. An international team of researchers from the Universities of Leeds, Stanford (USA) and Konstanz (Germany) have discovered that the nascent polypeptide-associated complex (NAC) helps to prevent the…
A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease (CMT). The findings point to a pathway to possible treatments for this disease and better understanding of other neurodegenerative disorders, including Alzheimer's disease, that affect millions. The study focused on two related proteins, MFN2 and…
Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation gives us answers to these questions. We spoke with Professor Thomas Wolbers about the problems of diagnosing orientation disturbances and how the measurement of our sense of space could help in the fight against neuro-degenerative illnesses such as Alzheimer’s.
Until now, neurologists were largely convinced that having a higher level of education would build some kind of protective barrier against neurodegenerative diseases like Alzheimer's. But a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the online issue of Neurology, the medical journal of the American Academy…
Poor sleep has long been linked with Alzheimer’s disease, but researchers have understood little about how sleep disruptions drive the disease. Now, studying mice and people, researchers at Washington University School of Medicine in St. Louis have found that sleep deprivation increases levels of the key Alzheimer’s protein tau. And, in follow-up studies in the mice, the research team has…
Alzheimer's disease is often marked by a creeping progression: Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tübingen now show that a protein found in the blood can be used…
In a new study, researchers at the Biodesign Institute explore a safe and simple treatment for one of the most devastating and perplexing afflictions: Alzheimer’s disease (AD). Lead authors Ramon Velazquez and Salvatore Oddo, along with their colleagues in the Arizona State University (ASU)-Banner Neurodegenerative Disease Research Center (NDRC), investigate the effects of choline, an important…
Using a common type of brain scan, researchers programmed a machine learning algorithm to diagnose early-stage Alzheimer's disease about six years before a clinical diagnosis is made – potentially giving doctors a chance to intervene with treatment.
Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias.
This could be a major step towards a better understanding of the functions of deeply hidden brain compartments, such as the formation of memories, as well as related dysfunctions, including Alzheimer’s disease. Researchers from the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena and the University of Edinburgh have succeeded in using a hair-thin fibre endoscope to gain insights…
Using artificial intelligence, metabolic brain changes can be identified earlier leading to timely diagnosis and intervention of Alzheimer’s disease.
One day, MRI brain scans may help predict whether older people will develop dementia, new research suggests. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years, according to research at Washington University School of Medicine in St. Louis and the University of California San Francisco. The findings, presented at the…
One in two women and one in three men will likely be diagnosed with dementia, Parkinson's disease, or stroke in their lifetime, estimate Dutch researchers in an observational study
Alzheimer’s is the most common form of dementia. The US Centers for Disease Control and Prevention reports as many as five million Americans had the disease in 2013. They estimate that by 2050, nearly 14 million will have it. Age is the best known risk factor and memory loss is at the forefront of symptoms. Researchers of the Michigan Technological University investigate how technology can…
