Novel drug ionophore shows potential for Alzheimer's

Scientists report a remarkable improvement in Alzheimer's transgenic mice following treatment with a new drug. The study, published by Cell Press in the July 10th issue of the journal Neuron, provides the first demonstration that an ionophore, a compound that transports metal ions across cell membranes, can elicit rapid and pronounced improvement in neuropathology and cognitive function in mouse models of Alzheimer's Disease (AD).

Evidence mounts against DHEA use in treating cognitive decline

DHEA supplements are widely-available and touted as a preventive agent for many chronic diseases. A new study published in Journal of the American Geriatrics Society finds no evidence of a beneficial effect of DHEA supplements on cognitive function in healthy older adults. The researchers believe that based on their study, DHEA supplements should not be recommended for enhancement of cognitive function or well-being in the general population.

Plant flavonoid luteolin reduces inflammatory response in the brain

Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer's and multiple sclerosis.

Bypass not to blame for heart patients' mental decline

Heart patients often experience lasting problems with memory, language, and other cognitive skills after bypass surgery. However, these problems aren't caused by the surgery itself or the pump used to replace heart function during surgery, a new study by Johns Hopkins researchers suggests. The findings may lead to better approaches to prevent cognitive decline regardless of which treatment heart disease patients receive.

Neuroimaging helps improve quality of life for brain tumor patients

A new neuroimaging study at the Montreal Neurological Institute and Hospital at McGill University aims to ensure the highest quality of life for patients by assessing their cognitive skills before, during, and after brain tumour surgery.
