The first successful surgery under anaesthesia occurred in the 1840s. Since then, people have been developing theories about what might be going on in the brain while a person is unconscious. Even after thousands of surgeries, researchers still don’t understand exactly which specific areas of the brain are responsible for transitioning into unconsciousness and back.
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…
New research from the Westmead Institute for Medical Research and the University of Sydney has found that neurons deep inside the brain could hold the key to accurately diagnosing bipolar disorder and depression.
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.
A recent study, performed in Chicago and Rabat, Morocco, found that a novel finger-prick test for infection with the parasite Toxoplasma gondii during pregnancy — and many other potential applications — is 100 percent sensitive and 100 percent specific for detecting the presence of this life-damaging microorganism.
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…
New research, published in the European Heart Journal, has shown deaths from conditions that affect the blood supply to the brain, such as stroke, are declining overall in Europe but that in some countries the decline is levelling off or death rates are even increasing. Cerebrovascular disease includes strokes, mini-strokes, and narrowing, blockage or rupturing of the blood vessels supplying…
Using a new approach called 'reinforced learning', researchers have taught an artificial intelligence (AI) to responsibly choose the right amount of chemo- and radiotherapy for glioblastoma patients. The technique, which is insprired by behavioural psychology, has given the AI the ability to master the tightrope walk between effective tumor shrinkage and the medications' severe side effects.
Everyone knows what our brains look like – but why is it folded up like that? Looking at other species reveals much less folding or even none at all. Scientists in Dresden, Germany, have now taken a closer look at the ridges and grooves of human brains. They discovered what causes our brains to fold – and what happens when the folding process goes wrong.
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…
Austrian researchers have accomplished an astounding feat: They created organoids that mimic the onset of brain cancer. This method not only sheds light on the complex biology of human brain tumors but could also pave the way for new medical applications.
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.
While soccer fans want to see which team really has their head in the game, the players themselves might want to watch out for the consequences of headers. They may be more likely to experience short-term balance problems, suggesting that repetitive head impacts could have the potential to cause subtle neurological deficits not previously known, according to a preliminary study.
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.
A team of neurobiologists has identified a novel neuronal circuit in the midbrain that gates fear learning. They think that associative learning of fear is mediated by a novel dopamine circui.
An anxious person will avoid risks whenever possible. This in itself is not exactly a surprise. However, researchers have found a way to visualize this process in the brain - with interesting implications for behaviour prediction. A team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg, Germany and Victoria, Canada they conducted an…
Being left-handed apparently means a lot more than gripping things differently than most, researchers find. This sheds a new light on mental health treatment, because current therapies for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population. For more than 40 years, hundreds of studies suggest that each hemisphere of the brain is…
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,…
An international Phase 3 study has found that a personalized glioblastoma vaccine may increase long-term survival in some patients.
