Despite Brain Damage, Working Memory Functions – Within Limits

Researchers at the University of California, San Diego School of Medicine, led by Larry R. Squire, PhD, professor of psychiatry, psychology and neurosciences at UC San Diego and a scientist at the VA San Diego Healthcare System, report that working memory of relational information – where an object is located, for example – remains intact even if key brain structures like the hippocampus are damaged.

Carotid Stents Linked With Greater Risk of Stroke or Death Than Carotid Endarterectomy Surgery

For patients with blockages in the carotid artery that supplies blood to the brain, carotid artery stenting (a non-surgical treatment) appears to be associated with an increased risk of both short- and long-term adverse outcomes when compared with surgical treatment (carotid endarterectomy), according to a meta-analysis of previously published studies that was posted online today and will appear in the February 2011 print issue of Archives of Neurology, one of the JAMA/Archives journals.

Insulin Resistance May Be Associated With Stroke Risk

Insulin resistance, a condition in which insulin produced by the body becomes less effective in reducing blood glucose levels, appears to be associated with an increased risk of stroke in individuals without diabetes, according to a report in the October issue of Archives of Neurology, one of the JAMA/Archives journals.

By comparing a clearly defined visual input with the electrical output of the retina, researchers at the Salk Institute for Biological Studies were able to trace for the first time the neuronal circuitry that connects individual photoreceptors with retinal ganglion cells, the neurons that carry visuals signals from the eye to the brain.

Blood Test Could Diagnose Alzheimer’s Disease

A set of proteins found in blood serum shows promise as a sensitive and accurate way to diagnose Alzheimer’s disease, researchers at UT Southwestern Medical Center have found as part of a statewide study.

Early Use of Hypertonic Fluids Does Not Appear to Improve Outcomes For Severe Traumatic Brain Injury

Patients with a severe traumatic brain injury (and not in shock because of blood loss) who received out-of-hospital administration of hypertonic fluids (a solution with increased concentration of certain electrolytes and thought to help reduce intracranial pressure) as initial resuscitation did not experience better 6-month neurologic outcomes or survival compared to patients who received a normal saline solution, according to a study in the October 6 issue of JAMA.

New Clues on Why Some People with Parkinson’s Die Sooner

New research shows how old people are when they first develop Parkinson’s disease is one of many clues in how long they’ll survive with the disease. The research is published in the October 5, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Study Shows Rising Rate of Brain and Spinal Injuries in ATV Riders

Brain and spinal cord injuries related to all-terrain vehicles (ATVs) appear to be increasing, reports a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, and pharmacy.
