See-through Brains Ready for Study

2015 18 Sep

A new technique for creating transparent tissue has enabled Japanese researchers to visualise brain anatomy in 3D, giving them new insights into Alzheimer's disease plaques. "While Superman's x-ray vision is only the stuff of comics, our method, called Sca/eS, is a real and practical way to see through brain and body tissue," says lead scientist Atsushi... Read more

Cardiovascular Risk Factors May Predict Alzheimer’s Disease

2015 28 Jul

An imaging study shows that specific cardiovascular risk factors, such as alcohol use, smoking, obesity and diabetes, correlate with smaller regional brain volumes that may be early indicators of Alzheimer’s disease and dementia. The findings are reported in the journal Radiology.Previous studies have linked cardiovascular risk factors and cognitive... Read more

Insulin Resistance Increases Risk for Alzheimer's Disease

2015 28 Jul

An imaging study finds a strong association between insulin resistance and lower brain glucose metabolism in a group of late middle-age adults at risk for Alzheimer's disease (AD). The findings are published online in JAMA Neurology.Insulin resistance, broadly defined as reduced tissue responsiveness to the action of insulin, is common in people who... Read more

Cell Density Unchanged as Brain Shrinks With Age

2015 16 Jun

Using a powerful 9.4-Tesla MRI — the first of its kind for human imaging — researchers at the University of Illinois at Chicago have obtained the most detailed MRI images of the brain so far to show that while the brain shrinks with age, brain cell density remains constant. The findings are reported in the journal NMR in Biomedicine.The 9.4-Tesla images... Read more

Brain Imaging Boosts Efforts to Lower Alzheimer's Risk

2015 08 Jun

A report published in American Journal of Neuroradiology (AJNR) discusses how cognitive decline can be identified early and prevented by applying quantitative brain imaging techniques. Amidst growing evidence that neurodegenerative diseases alter brain structures, use of quantitative brain imaging is gaining popularity among clinicians as this helps... Read more

Imaging Test May Identify Biomarker of Alzheimer’s Disease

2015 27 May

A new study published in Radiology reveals that degeneration of the brain's white matter may be an early marker of specific types of Alzheimer’s disease (AD), including early-onset AD. Researchers used diffusion tensor imaging (DTI) to assess the white matter tracts in 53 patients with three types of AD: early-onset AD and two atypical types of AD called... Read more

Healthy Heart Could Prevent Alzheimer's Disease

2015 05 Mar

A healthier heart could prevent Alzheimer's disease, according to a new study associating heart function with the development of dementia and Alzheimer's disease. Participants with decreased heart function, measured by cardiac index, were two to three times more likely to develop significant memory loss over the follow-up period."Heart function could...

RSNA 2014: An Imaging Biomarker of Alzheimer’s Disease?

2014 01 Dec

Based on findings of a new study, changes in brain connections visible on MRI could represent an imaging biomarker of Alzheimer's disease, the most common form of dementia. For this study, researchers examined the brain's structural connectome, a map of white matter tracts that carry signals between different areas of the brain."The structural connectome... Read more

Focused Ultrasound and the Brain

2014 08 Nov

Why is high-intensity focused ultrasound being explored to treat the brain? For a number of brain disorders focused ultrasound (FUS) will represent a treatment that is either superior to best current therapy, or fulfils an unmet clinical need. The driving factor is a validation of the technology. It doesn’t take an enormous leap of faith to appreciate... Read more
