In healthy individuals, the Zika virus causes flu-like symptoms. If a pregnant woman becomes infected, the unborn child can suffer from severe brain abnormalities as a result of mechanisms that have not yet been explained. A study by the Technical University of Munich (TUM) and the Max Planck Institute of Biochemistry (MPI-B) shows that Zika virus proteins bind to cellular proteins that are…
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.
An international collaboration between Imperial College London, Singapore's Duke-NUS Medical School and Belgium-based pharmaceutical company UCB led to the discovery of a new anti-epileptic drug target and a whole new approach that promises to speed up the discovery of future drugs to treat debilitating diseases, such as epilepsy.
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research. The study, led by researchers at the Montreal Neurological Institute and Hospital (The Neuro), was an examination of MRI and cognitive test data from 1,200 individuals, supplied as part of the Human…
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.
Glioblastoma brain tumors can have an unusual effect on the body's immune system, often causing a dramatic drop in the number of circulating T-cells that help drive the body's defenses. Where the T-cells go has been unclear, even as immunotherapies are increasingly employed to stimulate the body's natural ability to fight invasive tumors. Now researchers have tracked the missing T-cells in…
Neurologist who coined the phrase "Time is Brain" says message is not so simple anymore. Rather there should be no hard-and-fast rule governing when therapy can be given because strokes progress differently in different patients.
Charcot-Marie-Tooth (CMT) disease is the most common hereditary neuropathy and affects more than two million people worldwide. In Germany, at least 30.000 people suffer from CMT which belongs to the class of rare disease. In a close collaboration, researchers at the Max-Planck-Institute for Experimental Medicine and the University Medical Center of Göttingen now hope to use lecithin, a harmless…
People who abstain from alcohol or consume more than 14 units a week during middle age (midlife) are at increased risk of developing dementia, finds a study in The BMJ today. However, the underlying mechanisms are likely to be different in the two groups. As people live longer, the number living with dementia is expected to triple by 2050. So understanding the impact of alcohol consumption on…
About a third of epilepsy sufferers require treatment through surgery. To check for severe epilepsy, clinicians use a surgical procedure called electrocorticography (ECoG). An ECoG maps a section of brain tissue to help clinicians identify areas damaged by seizures.
The electromagnetic radiation emitted from smartphones and similar devices may have negative effects on the memory of young people. Research conducted in Switzerland suggests that it might be a good idea to get rid of your smartphone from time to time.
The exchange of a single amino acid building block in a metabolic enzyme can lead to cancer. In addition, it can impair the immune system. It thus blocks the body’s immune response in the battle against the mutant molecule and also impedes immunotherapy against brain cancer. This finding opens new insights into cancer development and progression and it also suggests that rethinking antitumor…
SLAC and Stanford researchers are developing a device that combines electrical brain stimulation with EEG recording, opening potential new paths for treating neurological disorders. It could help bring back lost brain function by measuring how the brain responds to therapies that stimulate it with electric current.
When light streams through her window in just the right way, Milena Canning will sometimes stoop to pick up a shiny coin she has noticed on the wooden floor of her Glasgow-area home. But her hand comes up empty – the 'coin' is just a dancing sunbeam, a quirk of perception in Canning's extraordinary world.
Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain,…
When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and early 1990s, MTV had only one format—music videos—and that genre…
The way you walk can reveal current and future health problems. New research from Halmstad University suggests the use of wearable sensors for analysing your movement. This can potentially result in early detection of for example Parkinson’s disease, dementia, multiple sclerosis and other neuro-physiological disorders. Many of our body systems, such as the cardio-vascular system and the…
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. The results could encourage seniors, caregivers and health care providers to pursue or prescribe exergames in hopes of slowing the debilitating effects of those with MCI.
The APOE gene, the strongest genetic risk factor for Alzheimer’s disease, may play a more prominent role in disease development among women than men, according to new research from the Vanderbilt Memory and Alzheimer’s Center. The research confirmed recent studies that carrying the APOE ε4 allele has a greater association with Alzheimer’s disease among women compared to men, and went one…
Seasonal allergies can be a nuisance for children as well as adults. And in some young children, the symptoms of seasonal allergies can be mistaken for inattentiveness or learning disabilities. Dr. Maria Garcia-Lloret, a pediatric allergist at the UCLA Mattel Children's Hospital, explains that certain symptoms characteristic of learning disabilities or behavioral problems, such as fidgeting and…
Ever get chills listening to a particularly moving piece of music? You can thank the salience network of the brain for that emotional joint. Surprisingly, this region also remains an island of remembrance that is spared from the ravages of Alzheimer’s disease. Researchers at the University of Utah Health are looking to this region of the brain to develop music-based treatments to help alleviate…
New research from the University of Adelaide has found that taking vitamin B6 could help people to recall their dreams. The study published online ahead of print in Perceptual and Motor Skills, included 100 participants from around Australia taking high-dose vitamin B6 supplements before going to bed for five consecutive days. "Our results show that taking vitamin B6 improved people’s…
The first patient in a multicenter pivotal trial using focused ultrasound to address the major motor symptoms of Parkinson’s disease has been treated at Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center in New York. This randomized, double-blind clinical trial is evaluating the safety and efficacy of using Insightec’s Exablate Neuro device in more than 100 patients…
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…
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. And finding that common thread could lead to a treatment that could work for all three. A recent study by David Smith, associate professor of biochemistry in the West Virginia University School of Medicine, suggests that at the heart of all three…
