Deep-Brain Stimulation: Surgical Relief for Parkinson's and Beyond

In this series, ARF takes stock of deep-brain stimulation after more than a decade of life-altering procedures,  In deep brain stimulation, surgeons implant wires into the brain and hook them up to a pacemaker-like stimulator implanted in the chest, which

Preimplantation Genetic Diagnosis: A Family Choice

For families with autosomal-dominant neurological conditions, the fear of passing on the disease to their children looms large. Now, people at this highest genetic risk can ensure that they have healthy children by undergoing in vitro fertilization follow

DIAN: International Network to Chart AD Preclinical Decade

The rarest kind of Alzheimer's disease, the form that is inherited from parent to child with a cruel 50 percent likelihood, has long been marked by its untapped opportunities. Affected families have made possible both the discovery of the first three

AD Biomarker Labs Can Get Standard Protocol, Quality Control

Did you know that if you had a spinal tap for a cerebrospinal fluid-based Alzheimer's diagnosis in Boston, Stockholm, London, or San Diego, the readout would likely be different in each place? And different again this year and next? That's a pro
