Neurodegeneration News and Research

RSS

Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.

Highly promising Alzheimer's and Parkinson's research

The TI Pharma project is a large-scale study into the brain material of Alzheimer's and Parkinson's patients, who gave permission to the Netherlands Brain Bank for their tissue to be used for scientific research.

New model for neurodegeneration

The gradual loss of dopamine neurons is a hallmark of many neurodegenerative diseases - Parkinson's Disease chief among them.

Melatonin could actually be hurting you at night!

What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep?

From successful aging to severe dementia

A recently published special issue of the Journal of Alzheimer's Disease contains the contributions from experts in the field of aging, dementia and Alzheimer's disease, who attended the "Fourth Annual Meeting on Brain aging and Dementia - From successful aging to severe dementia”, Held in Perugia in October 2006 under the auspices of the Italian Psychogeriatric Association, a member of the International Psychogeriatric Association, the meeting celebrates the centenary of Alzheimer's first description of the disease.

Abnormal glutamine repeats interfere with key transcription factor, leading to neurodegeneration

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.

New target for MS treatment found using old drug

A drug currently used to treat high blood pressure and heart failure has been found to reduce the symptoms of multiple sclerosis in mice.

Herb rosemary fights free radical damage in the brain

Rosemary not only tastes good in culinary dishes such as Rosemary chicken and lamb, but scientists have now found it is also good for your brain.

New brain cells listen before they talk

Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells - a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine researchers report in The Journal of Neuroscience.

Lithium commonly used to treat bi-polar disorder increases lifespan in Nematode worms

Nematode worms treated with lithium show a 46 percent increase in lifespan, raising the tantalizing question of whether humans taking the mood affecting drug are also taking an anti-aging medication.

Aggregation propensity, amyloid peptide toxicity and Alzheimer disease

Cells have evolved multiple mechanisms to ensure proper folding, but a number of molecular and biophysical events - such as changes in pH or temperature, mutations, and oxidation - can disrupt a protein's native shape.

Scientists discover new causes for neurodegeneration

Diseases that cause neurons to break-down, such as Alzheimer's, Multiple Sclerosis and Creutzfeldt-Jakob disease (Mad Cow Disease), continue to be elusive to scientists and resistant to treatments.

The accumulation of sugar in neurons may explain the origin of several neurodegenerative diseases

A phenomenon considered healthy for cells, such as the accumulation of long chains of glucose (glycogen), which tissues store for energy purposes, is harmful for neurons.

Benefits of exercise on the aging brain

Bradley Hatfield, professor in the University of Maryland, College Park, School of Public Health, uses high tech brain imaging to study the benefits of exercise on the aging brain.

Discovery of new pathway causing cell death related to frontotemporal dementia and ALS

Scientists have discovered a link between a mutated gene and a protein found in dead brain cells of people who suffer from a form of dementia and other neurological disorders.

Two genes in mammalian cells act as gatekeepers for cellular longevity

In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive.

Heat shock proteins are co-opted for cancer

A Jekyll-Hyde mechanism that both protects healthy cells and enables cancer cells could be the basis for new cancer-fighting drugs.

Cell-surface sugar defects may trigger nerve damage in multiple sclerosis patients

Defects on cell-surface sugars may promote the short-term inflammation and long-term neurodegeneration that occurs in the central nervous system of multiple sclerosis patients, according to University of California, Irvine researchers.

Cell death in sparrow brains may provide clues in age-related human diseases

A remarkable change takes place in the brains of tiny songbirds every year, and some day the mechanism controlling that change may help researchers develop treatments for age-related degenerative diseases of the brain such as Parkinson's and dementia.

Rochester receives $1.2 million to battle rare childhood disease

"For an orphan disease like Batten, which has such a clear-cut course of deterioration and no present cure, this grant is transformative both for these families and for us, as clinicians and researchers."
