Study Finds Enzyme Disrupting Nerve Cell Communication in Alzheimer’s Disease
A modified form of the enzyme Cdk5 is elevated in the brains of Alzheimer’s disease patients, where it triggers damage to nerve cell connections. Alzheimer’s disease is characterized by abnormal proteins that stick together in little globs, disrupting cognitive function [Read More]
Lithium Profoundly Prevents Brain Damage Associated with Parkinson’s Disease
Buck Institute research in mice moves into preclinical stage; working toward human trials Lithium profoundly prevents the aggregation of toxic proteins and cell loss associated with Parkinson’s disease (PD) in a mouse model of the condition. Preclinical research is [Read More]
Competition Between Brain Cells Spurs Memory Circuit Development
From the Petri dish into a living organism, for the first time U-M scientists observe key aspects of how the brain shapes itself Scientists at the University of Michigan Health System have for the first time demonstrated how memory circuits in the brain refine themselves in [Read More]
Brain Scan Identifies Patterns of Plaques and Tangles in Adults with Down Syndrome
In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer’s disease — in adults with Down syndrome. Published in the June edition of the [Read More]
UCSB Scientists Discover New Direction in Alzheimer’s Research
In what they are calling a new direction in the study of Alzheimer’s disease, UC Santa Barbara scientists have made an important finding about what happens to brain cells that are destroyed in Alzheimer’s disease and related dementias. The results are published [Read More]
High Iron Or Copper Levels Block Brain-cell DNA Repair
No one knows the cause of most cases of Alzheimer's, Parkinson's and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is DNA damage by reactive oxygen species, highly [Read More]
Neutrons Provide First Sub-nanoscale Snapshots of Huntington’s Disease Protein
Energy’s Oak Ridge National Laboratory and the University of Tennessee have for the first time successfully characterized the earliest structural formation of the disease type of the protein that causes Huntington’s disease. The incurable, hereditary [Read More]
As Time Goes by, It Gets Tougher to ‘Just Remember This’
It’s something we just accept: the fact that the older we get, the more difficulty we seem to have remembering things. We can leave our cars in the same parking lot each morning, but unless we park in the same space each and every day, it’s a challenge eight [Read More]
63rd Annual Meeting of the American Academy of Neurology – 2011
The American Academy of Neurology is holding their 63rd annual meeting from April 9 - 16, 2011 in Honolulu, Hawaii, USA. [Read More]
Freeway Air Bad for Mouse Brain
Study finds brain damage typical of aging and memory loss after short-term exposure to vehicle pollution If mice commuted, their brains might find it progressively harder to navigate the maze of Los Angeles freeways. A new study reveals that after short-term exposure to [Read More]
