No increased risk of brain cancer from electromagnetic fields
Exposure to electromagnetic fields does not increase the risk of developing a brain tumour, finds a study of electricity industry workers, reported in Occupational and Environmental Medicine. Researchers from the Institute of Occupational Health at the University of Birmingham assessed causes of death among just under 84,000 workers employed in... view more... (2001-09-07)
Call for closer examination of 'brain death' as the end of life
The medical diagnosis of brain death is at odds with our traditional view of when death actually occurs. view more (2007-09-12)
Study finds significant differences in protocols hospitals use to determine brain death
A survey of some of the top hospitals in the country has found that protocols followed to determine brain death differ significantly among those institutions. view more (2008-01-18)
Matrix fragments trigger fatal excitement
Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org). view more (2008-12-30)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
New understanding about mechanism for cell death after stroke leads to possible therapy
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. view more (2009-11-23)
Scientists find a key culprit in stroke brain cell damage
Researchers have identified a key player in the killing of brain cells after a stroke or a seizure. The protein asparagine endopeptidase (AEP) unleashes enzymes that break down brain cells' DNA, scientists at Emory University School of Medicine have found. view more (2008-03-28)
Why don't brain tumors respond to medication?
Malignant brain tumors often fail to respond to promising new medication. Researchers in Heidelberg have discovered a mechanism and a tumor marker for the development of this resistance. view more (2009-09-01)
Anesthesia and Alzheimer's
In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein. view more (2008-04-28)
From Terror to Joy: Faced with Death, Our Minds Turn to Happier Thoughts
Philosophers and scientists have long been interested in how the mind processes the inevitability of death, both cognitively and emotionally. One would expect, for example, that reminders of our mortality--say the sudden death of a loved one--would throw us into a state of disabling fear of the unknown. But that doesn't happen. If the prospect of... view more... (2007-10-23)
Wellcome Trust grant to investigate degenerative brain diseases known as `tauopathies`
Dr Julian Thorpe, head of the Electron Microscopy Lab at the University of Sussex, will be working towards a better understanding of degenerative brain diseases thanks to a £247,000 grant from the Wellcome Trust. He is taking a very close look at a possible contributory cause of nerve cell death in a group of conditions related to... view more... (2002-04-17)
No pacemakers in the brain may explain cot death
A failure to 'gasp' has long been proposed as the basis for sudden infant death syndrome, or cot death. view more (2006-02-13)
Significant dementia risk attributable to small blood vessel damage
Autopsy data of 221 men and women found that the brains of one-third of individuals who had dementia before death showed evidence of small, cumulative blood vessel damage that can arise from hypertension or diabetes. view more (2008-04-07)
Inflammation kills new brain cells
A research team at Lund University in Sweden attracted international attention a year ago by showing that new nerve cells can be generated in the brain after a stroke. However, most of these new nerve cells die rather soon. The same research team has now been able to show that an inflammation can lie behind the death of these new nerve cells,... view more...

Post-mortem brain studies reveal features of mild cognitive impairment
The brains of patients with mild cognitive impairment display pathologic features that appear to place them at an intermediate stage between normal aging and Alzheimer's disease, although some patients with mild cognitive impairment develop other types of dementia. view more (2006-05-09)
New research promising for improving brain cell survival after brain injury
Scientists at Melbourne's Howard Florey Institute have found a protein in the brain that can save neurons from dying after experiencing traumatic brain injury from incidents such as stroke, car accidents and falls. view more (2006-07-11)
High hourly air pollution levels more than double stroke risk
High hourly levels of air pollution, more than double the risk of one type of stroke, suggests research published ahead of print in Occupational and Environmental Medicine. view more (2006-09-21)
Out-of-body experiences may be caused by arousal system disturbances in brain
Having an out-of-body experience may seem far-fetched to some, but for those with arousal system disturbances in their brains, it may not be a far off idea that they could sense they were really outside their own body watching themselves. In previous studies of more than 13,000 Europeans, almost 6 percent said they have had such an out-of-body... view more... (2007-03-06)
Paradigm shift: Switch for programmed cell death promotes spread of glioblastoma
Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis. Therefore, tumors are often resistant to chemotherapy or radiation therapy, whose effect is based on forcing tumor cells to commit suicide. view more (2008-03-12)
UAB Researchers Draft 3-D Protein Map
A new three-dimensional computer protein map is helping researchers at the University of Alabama at Birmingham (UAB) unravel the biological pathways that control brain-cell death after a stroke. view more (2009-06-25)
