Scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly-named pathway to dementia,…
The speed of the human brain is remarkable. Almost immediately upon being exposed to stimuli, neurons are activated, prompting subconscious reactions and, a fraction of a second later, thought. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen levels, has revolutionized neuroscience by…
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.

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…
It’s undeniable: the bulk of our population is growing older. Yet, this demographic change has not altered laboratory medicine: the reference values for many analyses are still based on data of a younger cohort. Inevitably this could lead to serious errors in the interpretation of older patients’ test results.
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.
Molecular imaging is an exciting field for scientists who are willing to explore and innovate, prominent Spanish physicist José María Benlloch pointed out when he reviewed some of the most impacting and recent innovations in his portfolio during a meeting in Valencia. ‘Our mission is to develop innovative sensitive and harmless medical imaging instruments for early detection of diseases and…
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…

The findings, presented at the…
A world where machines can be controlled by thought alone – such is the promise of so-called brain-computer interfaces (BCI). BCIs are both hardware and software communication systems that read brain and nerve signals, convert those into electrical signals and translate human thoughts into machine commands. Developers of BCIs rely on artificial intelligence, neural network models and big data…
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…
A drug which has been used to treat liver disease for decades could help to restore cells damaged by Alzheimer's, a new study from the University of Sheffield has found. The pioneering study discovered the drug ursodeoxycholic acid (UDCA) improves mitochondrial dysfunction – which is known to be a causative factor for both sporadic and familial Alzheimer's disease.
Researchers at the University of Florida have discovered that a modified version of an important immune cell protein could be used to treat Alzheimer's disease. The study reveals that soluble versions of a protein called TLR5 can reduce the buildup of amyloid plaques in the brains of Alzheimer's disease model mice and prevent the toxic peptide that forms these plaques from killing neurons.
The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…
MRI has developed rapidly over the past decade in Poland, where clinicians are combining MRI with PET and CT to highlight tumour growth or regression and perfusion. ‘The fact that MRI offers new software and programmes means we can diagnose pathologies more precisely and make a diagnosis faster than a few years ago,’ explained Poland’s national advisor on radiology and diagnostic imaging…
Scientists have uncovered a potential approach to treat one of the commonest causes of dementia and stroke in older people. Studies with rats found the treatment can reverse changes in blood vessels in the brain associated with the condition, called cerebral small vessel disease.
Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease. Numerous studies have already shown that a calorie-restricted diet can significantly delay age-related conditions in several organisms like flies, worms, fish and mice, and that it even improves fitness at old age. But who…
Older adults with mild cognitive impairment (MCI), often a precursor to Alzheimer’s, showed significant improvement with certain complex thinking and memory skills after exergaming, according to a new study.

Researchers at the University of Utah Health are looking to this region of the brain to develop music-based treatments to help alleviate…
Inflammatory reactions can change the brain’s immune cells in the long term – meaning that these cells have an ‘immunological memory’. This memory may influence the progression of neurological disorders that occur later in life, and is therefore a previously unknown factor that could influence the severity of these diseases. Scientists at the German Center for Neurodegenerative Diseases…
A study coordinated by the Institute of Neuroscience of the Universitat Autònoma de Barcelona (Inc-UAB) and in collaboration with the Karolinska Institutet (KI) in Sweden provides evidence that a long-term consumption of caffeine has negative effects for Alzheimer’s disease, worsening the neuropsychiatric symptoms appearing in the majority of those affected by the disorder. The research was…
Humans and other mammals have a lot in common. Depending on race, 80 to 98% of mammalian genetic makeup is identical to the human one. Nevertheless, the variety of life expectancy among mammals is huge; and so far, it was unclear, which impact the genetic makeup has on a species’ life span. In rodents, differences in life expectancy and morbidity during aging are particularly high: Despite…
Alzheimer’s, Parkinson’s and Huntington’s disease may have more in common than their effects on the functions of the brain and spinal cord.

The study, which will be published in the Journal of Experimental Medicine, raises hopes that drugs targeting…
While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease. “Prolonged intake of…
Mutations in the p63 protein lead to a number of disorders, but none is as severe as the AEC syndrome. Scientists at Goethe University Frankfurt in collaboration with a research group from the University of Naples Federico II have now discovered that this syndrome resembles diseases such as Alzheimer’s, Parkinson’s or ALS more closely than it does other p63-based syndromes. Their results,…
What if one of the prime suspects behind Alzheimer’s disease was a case of mistaken identity? Amyloid plaques, sticky buildup that accumulates in and around neurons in the brain, have long been believed to be an indicator of neurodegenerative disease. Most clinical drug trials for Alzheimer’s disease treatment have failed, presumably because they target these plaques. But according to Raymond…
For centuries, hands, eyes and ears were the physicians’ most important instruments when it came to detecting and diagnosing disease.

Among other…
Blood-thinning drugs not only reduce the risk of stroke in patients with atrial fibrillation (AF) but are also associated with a significant reduction in the risk of dementia, according to new research published today in the European Heart Journal.
Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta,…
In old age a variety of cellular processes decline and the risk to develop age-related diseases such as Alzheimer’s, Parkinson’s or Diabetes increases dramatically. But does ageing affect all organs and tissues in the body in the same way? And should drugs that are developed to improve health in old age have the same effect on every organ? Now scientists from the Max Planck Institute for…
A long-term study of nearly 3,000 adults, aged 57 to 85, found that those who could not identify at least four out of five common odors were more than twice as likely as those with a normal sense of smell to develop dementia within five years. Although 78 percent of those tested were normal – correctly identifying at least four out of five scents – about 14 percent could name just three out…

Long before symptoms of Alzheimer's disease become apparent to patients and their families, biological changes are occurring within the brain. Amyloid plaques, which are clusters of protein fragments, along with tangles of protein known as tau, form in the brain and grow in number, eventually getting in the way of the brain's ability to function. These biological changes can be detected early in…
New research led by the University of Hertfordshire, may significantly change the understanding of cognitive processes that are most impaired at very early stages of Alzheimer's disease. The findings could potentially be used to detect the condition at an earlier stage and improve diagnostic accuracy, by creating new cognitive tests that are more sensitive to brain pathology than ones currently…
Study reveals the surprising role of omega-3 fatty acids in keeping the blood-brain barrier closed
A simple eye test could help solve the biggest global cause of irreversible blindness, glaucoma. In clinical trials, the pioneering diagnostic test - developed by researchers at UCL Institute of Ophthalmology and the Western Eye Hospital - allowed doctors to see individual nerve cell death in the back of the eye.
All it takes is the flip of a protein “switch” within the tiny wire-like capillaries of the brain to increase the blood flow that ensures optimal brain function. New research has uncovered that capillaries have the capacity to both sense brain activity and generate an electrical vasodilatory signal to evoke blood flow and direct nutrients to nourish hard-working neurons.
Scientists are hoping that a single drug can treat two devastating brain diseases: Parkinson's and Alzheimer's. The drug is nilotinib, which is approved to treat a form of leukemia.

Moderate-to-severe traumatic brain injury is a known risk factor for diseases that gradually destroy the brain - such as late-onset Alzheimer's disease. Now, a new study links mild traumatic brain injury, or concussion, in people at genetic risk for Alzheimer's to accelerated brain deterioration and mental decline associated with the disease.
Genetics stepping ahead as Spain-based researchers develop biomedical robots that can help in the study of rare diseases, neurodegenerative disorders and cancer, as well as the creation of orphan drugs.
Scientists at Washington University School of Medicine in St. Louis have detailed the structure of a molecule that has been implicated in Alzheimer’s disease. Knowing the shape of the molecule — and how that shape may be disrupted by certain genetic mutations — can help in understanding how Alzheimer’s and other neurodegenerative diseases develop and how to prevent and treat them.
Illuminating blood vessels, opening the blood-brain barrier and delivering drugs. What will be the next big thing that tiny microbubbles can do?
“The medical rationale for stroke being a disease of the brain is overwhelming.” This is the key message of an urgent appeal launched by leading neurology experts in The Lancet.1 The authors are making public their concern about the classification of stroke in the draft revision of the “International Statistical Classification of Diseases and Related Health Problems” (ICD) after an…
Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's. Now, researchers at Johns Hopkins say they have pinpointed the protein at the end of that chain of events, one that delivers the fatal strike by carving up a cell's DNA. The find, they say, potentially…
