With the use of MRI scans, it is possible to distinguish between memory loss caused by Alzheimer’s disease and traumatic brain injury, according to a UCLA-led study. The finding[1] is important because it could help prevent a misdiagnosis of Alzheimer’s disease, which can be devastating for patients and their families. A previous study found that… Read more

Atrophied brain lesion volume is the sole marker from MRI scans that can accurately predict which patients with multiple sclerosis will progress to the most severe form of the disease, new research indicates. Secondary progressive MS, known as SPMS, typically appears 10 to 20 years after the initial onset and causes more physical and cognitive… Read more

Researchers commonly study brain function by monitoring two types of electromagnetism — electric fields and light. However, most methods for measuring these phenomena in the brain are very invasive. MIT engineers have now devised a new technique to detect either electrical activity or optical signals in the brain using a minimally invasive sensor for magnetic… Read more

Areas in the brains of children with Tourette’s syndrome have been identified that appear markedly different from the same areas in the brains of children who don’t have the neuropsychiatric disorder. Researchers at Washington University School of Medicine in St. Louis used MRIs for the finding. Tourette’s syndrome is defined by tics — involuntary, repetitive… Read more

In a new study using contrast-enhanced MRI, researchers have identified leakages in the blood-brain barrier (BBB) of people with early Alzheimer’s disease (AD). The findings suggest increased BBB permeability may be a key mechanism in the early stages of the disease. Researchers used contrast-enhanced MRI to compare 16 early AD patients with 17 healthy age-matched… Read more
