A new study shows the loss of parkin sharply reduces the level of another protein which usually helps protect neurons from stress.
Mice that carry a gene associated with red hair have reduced production of dopamine in the substantia nigra and are more susceptible to toxins that can damage these dopaminergic neurons.
Maternal exposure to higher levels of air pollution is associated with lower IQ scores in their children. For those whose mothers were in the highest 10% of exposure had IQ score that were, on average, 2.5 points lower than those whose mothers were in the lowest 10%. However, higher maternal folate levels appear to neurtralize the effect of high pollution exposure on offspring.
Age related neurodegeneration may be delayed by preventing oxidative damage in a few neuron types, researchers report.
Older adults who consume tart cherry juice daily may have improved cognitive function. Researchers believe this may be due to anti-oxidative and anti-inflammatory properties of the cherries.
A link has been identified between oxidative stress, which has previously been linked to aging and neurodegeneration, and sleep. Oxidative stress activates neurons that control sleep function. The findings could help in the development of treatments for sleep disorders.
An examination of brainstems from children and young adults constantly exposed to air pollution reveals markers of Alzheimer's disease, Parkinson's disease, and motor neuron disease. Findings suggest air pollution poses risks of serious neurological damage from an early age.
A new neuroimaging study finds iron is distributed in an unusual way in the brains of people with Parkinson's disease.
N-acetylcysteine appears to help enable dopamine neurons to recover some function, researchers report.
Researchers report they have discovers a new class of mediators, named elovanoids. These bioactive chemical messengers are created from omega-3 very long chain polyunsaturated fatty acid and released in response to cell injury. The findings are reported in Scientific Reports.
