An errant enzyme linked to bipolar disorder, in the brain’s prefrontal cortex, impairs cognition under stress, an animal study shows. The disturbed thinking, impaired judgment, impulsivity, and distractibility seen in mania, a destructive phase of bipolar disorder, may be traceable to overactivity of protein kinase C (PKC), suggests the study, funded by the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) and National Institute on Aging (NIA), and the

Russian researchers have developed a small, smart and tolerant to vibrations spectrometer, which is equally reliable in the outer space and in oceanic depths. The development was performed with financial support from the Russian Foundation for Basic Research (RFBR) and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The unique device is based on a completely new principle: the light goes through an acoustooptical filter in the device.

A test that generally is used to measure the amount of vitamin B12 in the body is not sensitive enough to detect a deficiency of the vitamin, which has been linked to several neurological conditions, according to Saint Louis University research. The findings were presented this month at a meeting of the American Neurological Association.

“B12 deficiency is associated with dementia, peripheral neuropathy and spinal cord disease,” says Florian Thomas, M.D., Ph.D., associate profess

A little over a year ago, the Flanders Interuniversity Institute for Biotechnology (VIB), the D. Collen Research Foundation, and the Catholic University of Leuven invested in the acquisition of a new technology provided by the zebra fish. This small aquarium fish can be used to aid the study of the function of human genes. That this investment is reaping returns is evident from the study that VIB researchers at the Catholic University of Leuven are publishing today in the renowned journal Nature.

American Academy of Neurology and the American Neurological Association, together representing more than 18,000 neurologists and neuroscience professionals, today announced their support for government funding of adult and embryonic stem cell research.

The “The AAN and ANA recognize there are differing ethical opinions on the status of embryos that cannot be resolved to the satisfaction of all through medical science alone,” according to American Academy of Neurology president Sand

Retina specialists and ophthalmologists are encouraged by promising new scientific approaches that could have the potential to reduce the devastating effects of wet AMD for patients and offer the medical community a new paradigm of care, according to presentations made at the 2004 Annual Meeting of the American Academy of Ophthalmology in New Orleans.

Many experts consider AMD, the leading cause of blindness in Americans over age 50, as a growing public health epidemic. Diagno
