A new Mayo Clinic study may help physicians differentially diagnose three common neurodegenerative disorders in the future. The study will be presented at the Alzheimer's Association International Conference on Alzheimer's Disease on July 11 in Vienna.

A new study reveals a link between dysregulation of a common signaling pathway and repetitive behaviors similar to those associated with multiple neurological and neurodegenerative disorders including, autism spectrum disorders, obsessive compulsive disorder, schizophrenia, and Huntington's disease.

Genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found.

Parkinson's disease is a degenerative disorder of the brain affecting movement, speech, mood, behavior, thinking and sensation for which there is no known cause or cure.

In recent months a spate of mutations have been found in a disease protein called TDP-43 that is implicated in two neurodegenerative disorders: amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, and certain types of frontotemporal dementia (FTD). These mutations could potentially become candidates for drug targets.

Do you remember the seventh song that played on your radio on the way to work yesterday? Most of us don’t, thanks to a normal forgetting process that is constantly “cleaning house” – culling inconsequential information from our brains. Researchers at the Buck Institute now believe that this normal memory loss is hyper-activated in Alzheimer’s disease (AD) and that this effect is key to the profound memory loss associated with the incurable neurodegenerative disorder.

Individuals with a neurodegenerative condition affecting language appear more likely to have had a history of learning disabilities than those with other types of dementia or with no cognitive problems, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals.

Parkinson’s disease, the most common neurodegenerative movement disorder caused by aging, can also be caused by pesticides and other neurotoxins. A new study found strong evidence that trichloroethylene (TCE) is a risk factor for parkinsonism, a group of nervous disorders with symptoms similar to Parkinson’s disease.

Although repeating sequences of three nucleotides encoding some of the bodies' 20 amino acids are a normal part of protein composition, abnormal expansion of trinucleotide repeats is the known cause of multiple inherited neurodegenerative disorders, including Huntington disease.

Scientists have discovered a key protein in the toxic brain pathway that leads to fragile X tremor/ataxia syndrome (FXTAS), an inherited neurodegenerative disorder. The finding, in a Drosophila (fly) model of FXTAS, could help unravel the complex mechanisms of FXTAS and lead scientists to develop therapies to target the protein. The research will be published in the Aug. 16 issue of the journal Neuron.

An international team of researchers has published a benchmark study showing that gene expression in several animal models of Huntington’s Disease (HD) closely resembles that of human HD patients.

An enzyme involved in the formation of the amyloid-beta protein associated with Alzheimer's disease can also alter the mechanism by which signals are transmitted between brain cells, the disruption of which can cause seizures.
