Researchers report on the role of brain cell membranes' lipids in Alzheimer's progression

Alzheimer's disease is predominant in elderly people, but the way age-related changes to lipid composition affect the regulation of biological processes is still not well understood. Links between lipid imbalance and disease have been established, in which lipid changes increase the formation of amyloid plaques, a hallmark of Alzheimer's disease. This imbalance inspired researchers from

An analysis links COVID-19 to brain microvascular injury and inflammation

The ongoing COVID-19 pandemic is caused by the severe acute respiratory syndrome-2 (SARS-CoV-2), an RNA virus that belongs to the family Coronaviridae.  According to research, coronavirus disease 2019 (COVID-19) patients often suffer from neurological disorders like strokes, lost taste or smell, memory loss, confusion, and delirium. By comparing the symptoms associated with other coronavirus infections,

Brain study may lead to new treatments for neuro-immune conditions

The immune system is the brain's best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration. Two new studies in mice suggest that the double-edged nature of the relationship between the immune system and the brain may come down to

Brain research gets a boost from mosquitoes

Can a protein found in a mosquito lead to a better understanding of the workings of our own brains? Prof. Ofer Yizhar and his team in the Weizmann Institute of Science’s Neurobiology Department took a light-sensitive protein derived from mosquitoes and used it to devise an improved method for investigating the messages that are passed

Chaperone protein imbalance promotes toxic tau buildup in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain—an early step in the development of Alzheimer’s disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests. In humans, misfolding of the protein tau leads

Researchers visualize fast brain signals from outside the skull

The brain processes information using both slow and fast currents. Until now, researchers had to use electrodes placed inside the brain in order to measure the latter. For the first time, researchers from Charité – Universitätsmedizin Berlin and the Physikalisch-Technische Bundesanstalt (PTB), Berlin Institute, successfully visualized these fast brain signals from the outside – and

Disrupted biochemical pathway in the brain linked to bipolar disorder

Bipolar disorder affects millions of Americans, causing dramatic swings in mood and, in some people, additional effects such as memory problems. While bipolar disorder is linked to many genes, each one making small contributions to the disease, scientists don’t know just how those genes ultimately give rise to the disorder’s effects. However, in new research,

How oral health may affect your heart, brain and risk of death

Dental cavities could significantly increase the risk of a life-threatening stroke from bleeding in the brain, according to new research. Past studies have shown a link between gum infection and stroke, but few studies have looked into what role dental cavities might play. In the new study, researchers looked specifically at cavities and intracerebral stroke,

Music-based interventions can improve stroke, Parkinson's disease

Music-based interventions have become a core ingredient of effective neurorehabilitation in the past 20 years thanks to the growing body of knowledge. In this theme issue of Neurorehabilitation, experts in the field highlight some of the current critical gaps in clinical applications that have been less thoroughly investigated, such as post-stroke cognition, traumatic brain injury,
