A leading group of Alzheimer's researchers contends that, as biomarkers to detect signals of the disease improve at providing clinically meaningful information, researchers will need guidance on how to constructively disclose test results and track how disclosure impacts both patients and the data collected in research studies.

The network of arteries supplying blood flow to the brain is more likely to be incomplete in people who suffer migraine, a new study by researchers in the Perelman School of Medicine at the University of Pennsylvania reports.

A small percentage of people diagnosed with a mysterious neurological condition may only experience psychiatric changes - such as delusional thinking, hallucinations, and aggressive behavior - according to a new study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Researchers in the Perelman School of Medicine at the University of Pennsylvania found that, across a variety of neurodegenerative diseases, cerebrovascular disease affecting circulation of blood in the brain was significantly associated with dementia.

Neurodegenerative diseases are not all alike. Two individuals suffering from the same disease may experience very different age of onset, symptoms, severity, and constellation of impairments, as well as different rates of disease progression.

The motor neuron disease Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, progresses in a stepwise, sequential pattern which can be classified into four distinct stages, report pathologists with the Perelman School of Medicine at the University of Pennsylvania in the Annals of Neurology.

Researchers in the Perelman School of Medicine at the University of Pennsylvania have determined the role of a key growth factor, found in skin cells of limited quantities in humans, which helps hair follicles form and regenerate during the wound healing process.

Deep brain stimulation (DBS) in a precise region of the brain appears to reduce caloric intake and prompt weight loss in obese animal models, according to a new study led by researchers at the University of Pennsylvania.

Neurosurgeons can visualize important pathways in the brain using an imaging technique called diffusion tensor imaging (DTI), to better adapt brain tumor surgeries and preserve language, visual and motor function while removing cancerous tissue.
