Women on hormone therapy regain emotion response
Older women on hormone therapy are more sensitive to negative events, confirming speculation that age-related estrogen loss affects the brain's ability to process emotion, an Oregon Health & Science University study shows. view more (2006-10-17)
Scientists use gene therapy to improve memory and learning in animals
Stanford University neuroscientists have designed a gene that enhances memory and learning ability in animals under stress. view more (2006-11-08)
Alzheimer's disease therapeutic prevents long-term damage from TBI in pre-clinical studies
A class of Alzheimer's disease drugs currently studied in clinical trials appears to reduce damage caused by traumatic brain injury in animals, researchers at Georgetown University Medical Center report in an upcoming advance online publication of Nature Medicine. view more (2009-03-16)
Study links Alzheimer's disease to abnormal cell division
A new study in mice suggests that Alzheimer's disease (AD) may be triggered when adult neurons try to divide. The finding helps researchers understand what goes wrong in the disease and may lead to new ways of treating it. view more (2006-01-18)
Automated analysis of MR images may identify early Alzheimer's disease
Analyzing MRI studies of the brain with software developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) may allow diagnosis of Alzheimer's disease and of mild cognitive impairment, a lesser form of dementia that precedes the development of Alzheimer's by several years. view more (2009-05-22)
Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal
A team of scientists at the Weizmann Institute of Science, led by Prof. Michal Schwartz of the Neurobiology Department, has come up with new findings that may have implications in delaying and slowing down cognitive deterioration in old age. view more (2006-01-16)
Gene variant increases risk for alcoholism following childhood abuse
Girls who suffered childhood sexual abuse are more likely to develop alcoholism later in life if they possess a particular variant of a gene involved in the body's response to stress. view more (2007-06-26)
New study finds healthy children of Alzheimer patients show early brain changes
Medical College of Wisconsin researchers in Milwaukee have reported that children of Alzheimer's patients who are carriers of a genetic risk factor for Alzheimer's disease have neurological changes that are detectable long before clinical symptoms may appear. view more (2008-07-29)
Estrogen therapy likely must be given soon after menopause to provide stroke protection
For estrogen replacement to provide stroke protection, it likely must be given soon after levels drop because of menopause or surgical removal of the ovaries, scientists report in the Journal of Neuroscience. view more (2009-11-05)
Brain imaging and proteins in spinal fluid may improve Alzheimer's prediction and diagnosis
Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's. view more (2009-07-14)
Memory test and PET scans detect early signs of Alzheimer's
A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease. view more (2009-07-14)
Why antidepressants don't work for so many
More than half the people who take antidepressants for depression never get relief. view more (2009-10-26)
New insights into growth factor's role in brain development
New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined. view more (2009-02-03)
Strong magnetic fields aid severe depression
For severe depression, electro-shock therapy is nowadays the last hope. However, it can impair memory for weeks after therapy. A less aggressive alternative seems to be provided by what is known as "transcranial magnetic stimulation". view more (2005-07-13)
Genetic tags reveal secrets of memories' staying power in mice
A better understanding of how memory works is emerging from a newfound ability to link a learning experience in a mouse to consequent changes in the inner workings of its neurons. view more (2008-02-22)
Penn Researchers Pinpoint the Brain Waves That Distinguish False Memories From Real Ones
For the first time, researchers at the University of Pennsylvania are able to pinpoint brain waves that distinguish true from false memories, providing a better understanding of how memory works and creating a new strategy to help epilepsy patients retain cognitive function. view more (2007-10-24)
Key brain antioxidant linked to Alzheimer's and Parkinson's
A study conducted at the San Francisco VA Medical Center has identified a protein found in both mice and humans that appears to play a key role in protecting neurons from oxidative stress, a toxic process linked to neurodegenerative illnesses including Alzheimer's and Parkinson's diseases. view more (2005-12-15)
Even a little cooling helps after cardiac arrest
As many as 400,000 people in North America suffer sudden cardiac arrest. Only 30% have their hearts restarted, and only about 6% survive to hospital discharge. Once the heart is restarted, a significant factor for subsequent death is brain injury. view more (2006-05-18)
New neuroimaging analysis technique identifies impact of Alzheimer's disease gene in healthy brains
Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. view more (2009-11-18)
New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
