Higher Level of Certain Fatty Acid Associated with Lower Dementia Risk

...se the risk of dementia and Alzheimer’s disease, a neurodegenerative disorder that causes 70 percent of cases of dementia in the elderly, according to background information in the article. Recent studies have found that high levels of homocysteine, an amino acid that is derived from proteins in the diet and that can ...

Yeast Model Shows Promise as Alzheimer's Test

...lzheimer formally described characteristics of the neurodegenerative disease //which ultimately came to bear his name. While international efforts to learn about Alzheimer's disease and develop treatments have progressed significantly in recent years, a cure remains an elusive goal. A new research tool developed by ...

Downstate Researchers Target Multiple Sclerosis

...tivation of calpain is associated with a number of neurodegenerative and autoimmune diseases such as MS. It is known to destroy the myelin sheath that coats and protects the nerves. In a paper published in the Journal of Neuroimmunology, SUNY Downstate and Maimonides Medical Center researchers described the use of t...

Stem Cell Activity Deciphered in the Aging Brain

... also suggests the possibility of treating various neurodegenerative disorders, including Alzheimer's disease, dementia and depression, by stimulating the brain's ability to produce new nerve cells, said senior study investigator Ashok K. Shetty, Ph.D., professor of neurosurgery at Duke University Medical Center and m...

A Study Finds VENs Devastated in FTD

... behavior. Frontotemporal dementia (FTD), a common neurodegenerative condition, is characterized by early breakdown in social and emotional awareness and is accompanied by atrophy and dysfunction in the brain areas where VENs are located. A new study published in the December 2006 issue of Annals of Neurology. Led ...

Unfolded Proteins May Protect Cells from Dying

...cells cope with adversity. Diabetes, cancer, and neurodegenerative diseases including Huntington's and Parkinson's are linked to unfolded proteins. But Hermann Steller, head of the Strang Laboratory of Apoptosis and Cancer Biology at Rockefeller and a Howard Hughes Medical Institute investigator, focused on autosoma...

Study Offers Window into Human Behavior, Brain Disease

...ific degeneration is a unifying feature of all the neurodegenerative diseases. Dopamine-producing neurons in the substantia nigra region of the brain deteriorate in Parkinson's disease, motor neurons of the spinal cord and motor cortex degenerate in ALS and specific memory-forming medial temporal lobe neurons die in e...

How Many Genes Does It Take to Learn? Lessons from Sea Slugs

...l be a valuable tool for developing treatments for neurodegenerative diseases. "The authors have assembled a tremendous amount of data on gene transcripts associated with neuronal signaling pathways in Aplysia that sheds new light on evolutionary relationships of this very ancient and highly successful marine animal...

Higher Folate Levels Linked to Reduced Risk for Alzheimer’s Diseas

...rmation in the article. Delaying the onset of this neurodegenerative disease would significantly reduce the burden it causes. Researchers suspect that elevated levels of the amino acid homocysteine in the blood, which is linked to a higher risk for cardiovascular disease and stroke, may also increase the risk for Alzh...

Transdermal Vaccine Effective in Treating Alzheimer's Disease in Mice

...pler way of preventing or treating the devastating neurodegenerative disease with less likelihood of adverse immune reactions. The study was published online this week in The Proceedings of the National Academy of Sciences. “While many groups have shown vaccinating against the beta amyloid protein (Ab) can reduce...

Single Protein Plays A Major Role In Prion Diseases

...ay a role in the accumulation of toxic proteins in neurodegenerative diseases like Parkinson's," said Tricia Serio, an assistant professor in Brown's Department of Molecular Biology, Cell Biology and Biochemistry and lead researcher on the project. The findings from Serio and her team, which appear online in PLoS Bio...

Learning Slows Physical Progression of Alzheimer's Disease: Study

... study the disease. Alzheimer's is a progressive neurodegenerative disorder that affects more than 4.5 million adults in the United States. With an aging population, that number could approach 20 million by 2050. Alzheimer's is the third-leading cause of death, behind cancer and heart disease. Five percent of people...

How Ion Channels are Organized to Control Nerve Cell Communication?
