July 26, 2016 — Researchers have developed a new technique for imaging brain tissue at multiple scales, allowing them to image molecules within cells or take a wider view of the long-range connections between ... read more

Can a Brain Scan Early in a Period of Stress Predict Eventual Memory Loss?

July 26, 2016 — New research shows that even a brief period of stress -- as few as three days -- can cause the hippocampus to start shrinking. This shrinking of the hippocampus -- a change in the brain's ... read more

Study Compares Cognitive Outcomes for Treatments of Brain Lesions

July 26, 2016 — Among patients with one to three brain metastases, the use of stereotactic radiosurgery (SRS) alone, compared with SRS combined with whole brain radiotherapy, resulted in less cognitive deterioration ... read more

Changes in Teenage Brain Structure Provide Clues to Onset of Mental Health Problems

July 25, 2016 — Scientists have mapped the structural changes that occur in teenagers' brains as they develop, showing how these changes may help explain why the first signs of mental health problems often ... read more

Research Opens 'Black Box' of Malignant Melanoma

July 25, 2016 — A new study pinpoints when melanoma cells metastasize in the brain months before they develop into fatal tumors. According to the research, micro-tumor cells hijack astrogliosis, the brain's ... read more

Using Tau Imaging as Diagnostic Marker for Alzheimer Disease

July 25, 2016 — The accumulation of ?-Amyloid and tau proteins in the brain is hallmark pathology for Alzheimer disease. Recently developed positron emission tomography (PET) tracers, including [18F]-AV-1451, bind ... read more
