Researchers Unveil New Data, Diagnostic Tool at the World's Largest Alzheimer's Forum

July 26, 2016 — A new diagnostic tool that can identify Alzheimer's disease long before the onset of symptoms has been presented by researchers. They add that the tool also highlights the increasing prevalence ... read more

Among the Oldest Adults, Poor Balance May Signal Higher Risk for Dementia

July 25, 2016 — In a first-of-its-kind study, researchers examined whether four different measures of poor physical performance might be linked to increased dementia risk for people aged 90 and ... read more

Alzheimer's Disease in HIV-Positive Patient

July 25, 2016 — The first case of Alzheimer's disease diagnosed in an HIV-positive individual has been documented. The finding in a 71-year-old man triggers a realization about HIV survivors now reaching the ... 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

Developmental Differences in Late Preterm Babies May Not Emerge Until After Age Two

July 25, 2016 — Developmental differences in babies born four to six weeks early may not show up until after they turn two, a new study suggests. At age two, late preterm babies were developmentally on track with ... read more
