Researchers at NYU School of Medicine have found that elevated cerebrospinal fluid levels of phosphorylated tau231 (P-tau231), a damaged tau protein found in patients with Alzheimer's disease, may be an early diagnostic biomarker for Alzheimer's disease in healthy adults.

CHICAGO — Research suggests that religious belief can help protect against symptoms of depression, but a study at Rush University Medical Center goes one step further.
In patients diagnosed with clinical depression, belief in a concerned God can improve response to medical treatment, according to a paper in the Journal of Clinical Psychology.
DALLAS – Feb. 25, 2010 – Profoundly deaf children with cochlear implants to help them to hear rate their quality of life equal to their normal-hearing peers, according to new research from UT Southwestern Medical Center auditory specialists.
In addition, the earlier a child is implanted with a cochlear device and the longer he or she wears the device, the better overall quality of life the child reports and the more successful the child is in school, according to the findings, published in the February issue of Otolaryngology – Head and Neck Surgery.
Huntington's disease (HD) is a cruel, hereditary condition that leads to severe physical and mental deterioration, psychiatric problems and eventually, death. Currently, there are no treatments to slow down or stop it. HD sufferers are born with the disease although they do not show symptoms until late in life. In a new study published in The Journal of Neuroscience, Stephen Ferguson and Fabiola Ribeiro of Robarts Research Institute at The University of Western Ontario identified a protective pathway in the brain that may explain why HD symptoms take so long to appear.

Researchers at the Cleveland Clinic report the identification of a protein that is highly expressed in a subgroup of glioblastoma brain tumor cells and show that depletion of this protein increases the survival of mice with these tumors. This work will be published in the online open-access journal PLoS Biology.
New research from scientists in Liverpool has revealed the relationship between agility and vision in mammals. The study, published today in the Journal of Anatomy, sampled 51 species to compare the relationship between agility and vision between frontal eyed species, such as cats, to lateral-eyed mammals such as rabbits, to establish if the positioning of the eyes resulted in limitations to speed and agility.
An assessment has been developed which reliably predicts future performance in cognition and activities of daily living for patients with Alzheimer's disease. Researchers writing in BioMed Central's open access journal Alzheimer's Research & Therapy followed 597 patients over 15 years to identify factors associated with slow, intermediate and rapid progression.
Athens, Ga. – The anxiety that often accompanies a chronic illness can chip away at quality of life and make patients less likely to follow their treatment plan. But regular exercise can significantly reduce symptoms of anxiety, a new University of Georgia study shows.
PASADENA, Calif.—A collaborative team of neuroscientists at the California Institute of Technology (Caltech), the University of Iowa, the University of Southern California (USC), and the Autonomous University of Madrid have mapped the brain structures that affect general intelligence.
The study, to be published the week of February 22 in the early edition of the Proceedings of the National Academy of Sciences, adds new insight to a highly controversial question: What is intelligence, and how can we measure it?
The ability to recognise faces is largely determined by your genes, according to new research at UCL (University College London).
Published today in the Proceedings of the National Academy of Sciences, scientists found that identical twins were twice as similar to each other in terms of their ability to recognise faces, compared to non-identical twins.
Those who live in industrialized countries have easy access to healthy food and nutritional supplements, but magnesium deficiencies are still common. That's a problem because new research from Tel Aviv University suggests that magnesium, a key nutrient for the functioning of memory, may be even more critical than previously thought for the neurons of children and healthy brain cells in adults.
PITTSBURGH—While the otherworldly behavior of teenagers is well documented, University of Pittsburgh researchers have taken a significant step toward finally unraveling the actual brain activity that can drive adolescents to engage in impulsive, self-indulgent, or self-destructive behavior.
Amsterdam, February 22, 2010 – IOS Press announces publication of a special issue of NeuroRehabilitation: An International Journal (NRE) devoted specifically to hypoxic-ischemic brain injury (HI-BI), a significant disruption of brain function due to a deficient supply of oxygen to the brain. This is the first publication to present a consolidated overview of HI-BI. It provides a thorough review of neuropathophysiology, neuroimaging assessment, and evaluation and management of the neurological and neurobehavioral sequelae of these injuries in adults and children.
Stress raises the risk of memory loss and cognitive decline among older people with diabetes, research suggests.
Researchers at the University of Edinburgh studied more than 900 men and women aged between 60 and 75 with type-2 diabetes, which tends to be common after the age of 40.
They found that brain function slowed in participants with higher levels of the stress hormone cortisol.
