Imaging shows brain abnormalities in chronic fatigue syndrome patients

In a study that could help shed light on the complexities of chronic fatigue syndrome (CFS), the brains of patients with severe CFS were found to have structural abnormalities when analyzed with a combination of different imaging techniques.

Cognitive decline predicted by arterial spin labeling before symptoms appear

Arterial spin labeling (ASL), an MRI technique that doesn’t require contrast, may be able to depict early and subtle alterations in brain perfusion in cognitively normal older patients that can serve as a biomarker of preclinical dementia, according to a study published online in Radiology.
