(January 25, 2021) – Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report. […]

MRI helps unravel the mysteries of sleep

Our state of consciousness changes significantly during stages of deep sleep, just as it does in a coma or under general anesthesia. Scientists have long believed – but couldn’t be certain – that brain activity declines when we sleep. Most research on sleep is conducted using electroencephalography (EEG), a method that entails measuring brain activity […]

Six-fold rise in brain pressure disorder that affects mostly women

A brain pressure disorder that especially affects women, causing severe headaches and sometimes permanent sight loss, has risen six-fold in 15 years, and is linked to obesity and deprivation, a new study by Swansea University researchers has shown. Rates of emergency hospital admissions in Wales for people with the disorder were also five times higher […]

Hematopoietic stem cell transplants may provide long-term benefit for people with MS

MINNEAPOLIS – A new study shows that intense immunosuppression followed by a hematopoietic stem cell transplant may prevent disability associated with multiple sclerosis (MS) from getting worse in 71% of people with relapsing-remitting MS for up to 10 years after the treatment. The research is published in the January 20, 2021, online issue of Neurology®, […]

But Sam, who has autism, […]

T cells linked to myelin implicated in MS-like disease in monkeys

Scientists have uncovered new clues implicating a type of herpes virus as the cause of a central nervous system disease in monkeys that’s similar to multiple sclerosis in people. The findings, published in the Annals of Clinical and Translational Neurology, expand on previous work to understand the cause of the disease and potentially develop antiviral […]

Increased risk of Parkinson’s disease in patients with schizophrenia

A new study conducted at the University of Turku, Finland, shows that patients with a schizophrenia spectrum disorder have an increased risk of Parkinson’s disease later in life. The increased risk may be due to alterations in the brain’s dopamine system caused by dopamine receptor antagonists or neurobiological effects of schizophrenia. The record-based case-control study […]

Disagreeing takes up a lot of brain real estate

Yale researchers have devised a way to peer into the brains of two people simultaneously while are engaged in discussion. What they found will not surprise anyone who has found themselves arguing about politics or social issues. When two people agree, their brains exhibit a calm synchronicity of activity focused on sensory areas of the […]
