Brain Imaging in Children with Neurological Disorders Links Language Delay to Chromosome Deletion

A study team of radiologists and psychologists has found that children born with DNA copy number deletions in a specific region on chromosome 16 previously linked to neurodevelopmental problems show measurable delays in processing sound and language [1].

Genetic Risk Factor for Alzheimer’s Disease Impacts the Blood Brain Barrier

The most common genetic risk factor for Alzheimer’s disease (AD) disrupts the blood brain barrier, impeding oxygen and nutrient flow to the brain and exposing the brain to systemic toxins, according to a recent investigation led by scientists from the University of Rochester Center for Neurodegenerative and Vascular Brain Disorders [1].

Pain and the Prognosis for Dementia

While researchers are busy developing sophisticated laboratory tests to predict who will eventually succumb to Alzheimer’s disease, a seemingly mundane observation may provide one of the strongest predictors yet identified: pain.
