Currently, there are no drugs available to treat TBI: a variety of single drugs have failed clinical trials, suggesting a possible role for drug combinations. Testing this hypothesis in an animal model, researchers at SUNY Downstate Medical Center tested five drugs in various combinations. Their observations, published recently in the journal PLoS One, suggest a potentially valuable role for minocycline plus N-acetylcysteine to treat TBI.
Elevated levels of a growth protein in the brains of Alzheimer’s disease (AD) patients is linked to impaired neurogenesis, the process by which new neurons are generated, say researchers at the University of California, San Diego in today’s edition of The Journal of Neuroscience.
New research suggests that old age may not play a role in why older people become forgetful. According to a study published in the September 15, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology, the same brain lesions that are associated with dementia are responsible for mild memory loss in old age.
Simply getting older is not the cause of mild memory lapses often called senior moments, according to a new study by researchers at the Rush Alzheimer’s Disease Center. The study found that even the very early mild changes in memory that are much more common in old age than dementia are caused by the same brain lesions associated with Alzheimer’s disease and other dementias.

A new study shows that white men and boys are living longer with muscular dystrophy due to technological advances in recent years, but that the lives of African-American men and boys with muscular dystrophy have not been extended at the same rate. The research will be published in the September 14, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology.
A new study led by researchers at Columbia University Medical Center has identified a novel molecular pathway underlying Parkinson’s disease and points to existing drugs which may be able to slow progression of the disease. The pathway involved proteins – known as polyamines – that were found to be responsible for the increase in build-up of other toxic proteins in neurons, which causes the neurons to malfunction and, eventually, die. The study is the first to identify a mechanism for why polyamines are elevated in the first place and how polyamines mediate the disease.
A new look at tests of mental aging reveals a good news-bad news situation. The bad news is all mental abilities appear to decline with age, to varying degrees. The good news is the drops are not as steep as some research showed, according to a study published by the American Psychological Association.

A clue to the causes of autism and mental retardation lies in the synapse, the tiny intercellular junction that rapidly transfers information from one neuron to the next. Neuroscientists report that a protein called APC (adenomatous polyposis coli) plays a key role in synapse maturation, and APC dysfunction prevents the synapse function required for typical learning and memory.
