For several years, the pharmaceutical industry has tried to develop drugs that target a specific neurotransmitter receptor in the brain, the NMDA receptor. This receptor is present on almost every neuron in the human brain and is involved in learning and memory. NMDA receptors also have been implicated in several neurological and psychiatric conditions such as Alzheimer's disease, Parkinson's disease, schizophrenia and depression. But drug companies have had little success developing...

Dr. J G Moellendorf, DC, ND, LCP reports on recent research at the University of Leeds (United Kingdom) finding that natural polyphenols in green tea and red wine disrupt a primary step in the development of Alzheimer´s disease. Sturgeon Bay, WI (PRWEB) March 20, 2013 Many genetic and environmental risk factors have been pointed to as causing Alzheimer´s disease. An estimated 14 million baby boomers (born between 1946 and 1964) are expected to develop Alzheimer´s and other...

Johns Hopkins study links 1 family's rare gene mutation to brain cell abnormality and mental illness Johns Hopkins researchers have identified a rare gene mutation in a single family with a high rate of schizophrenia, adding to evidence that abnormal genes play a role in the development of the disease. The researchers, in a report published in the journal Molecular Psychiatry, say that family members with the mutation in the gene Neuronal PAS domain protein 3 (NPAS3) appear at high risk...

Hearing Mechanism Compared To Car Battery
2013-01-08 03:42:16

redOrbit Staff & Wire Reports - Your Universe Online One of the mechanisms involved in human hearing is similar to the operation of a car battery, according to a new study by researchers at the University of Iowa (UI). The scientists conducted their study using fruit flies, whose hearing mechanisms resemble that of humans. Specifically, the flies´ auditory system contains a protein that functions as a sodium/potassium pump, and is highly expressed in a specialized support...

Jackson Laboratory researchers led by Associate Professor Zhong-wei Zhang, Ph.D., have provided direct evidence that a specific neurotransmitter receptor is vital to the process of pruning synapses in the brains of newborn mammals. Faulty pruning at this early developmental stage is implicated in autism-spectrum disorders and schizophrenia. The definitive evidence for N-methyl-D-aspartate receptor (NMDAR) in pruning has eluded researchers until now, but in research published in the...

Alzheimer's disease is one of the most common causes of dementia. In Germany and Switzerland alone, around 1.5 million people are affected, and forecasts predict a doubling of the number of patients worldwide within the next 20 years. The accumulation of particular abnormal proteins, including amyloid-ß (Aβ) among others, in patients' brains plays a central role in this disease. Prof. Frank Heppner from the Department of Neuropathology at Charité and his...

Johns Hopkins team first identified biochemical clue to therapy in brain scans of people with MS Johns Hopkins researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS). In follow-up experiments on mice with a rodent form of MS, researchers were able to use an experimental compound to manipulate that same marker and dramatically improve learning and memory....

Scientists may have discovered why the standard treatment for Parkinson's disease is often effective for only a limited period of time. Their research could lead to a better understanding of many brain disorders, from drug addiction to depression, that share certain signaling molecules involved in modulating brain activity. A team led by Bernardo Sabatini, Takeda Professor of Neurobiology at Harvard Medical School, used mouse models to study dopamine neurons in the striatum, a region of...
