Depletion of antioxidant glutathione linked to Parkinson's in mice

Scientists at the Buck Institute have shown that mice suffering from a depletion of the antioxidant glutathione in dopamine-producing neurons developed nerve damage and symptoms associated with Parkinson's disease (PD) in humans.

War veterans with brain injuries show a faster decline in cognitive functioning as they age

A study of Vietnam war veterans who suffered brain injuries during the conflict has found that the men show a faster decline in their cognitive functioning as they grow older than veterans without such injuries.

Brain malfunction explains dehydration in elderly

As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate.

Researchers spearhead key genome initiative

The complete collection of genes - the genome - of a moss has been sequenced, providing scientists an important evolutionary link between single-celled algae and flowering plants.

Complex path to cell death shown by identification of new genes

Can a tiny winged insect's salivary glands really tell us about processes relevant to human disease? Yes, according to a new study by researchers at the University of Massachusetts Medical School (UMMS), who gained new insights into autophagy - a cellular degradation process associated with a form of programmed cell death - by studying the salivary gland cells of the fruit fly.

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.

Aging gracefully requires taking out the trash

Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration.

Data suggests chromium picolinate may improve cognitive function

Nutrition 21, Inc. has announced the results of a clinical study that showed daily supplementation with 1000 mcg of chromium as chromium picolinate improved cognitive function in older adults experiencing early memory decline.

Nematodes provide clues to dopamine's role in human aging diseases

Research carried out with a paintbrush bristle, a metronome, smelly chemicals and thousands of microscopic worms called nematodes may reveal important information about human aging diseases like Parkinson's and Alzheimer's, thanks to a grant from the Ellison Medical Foundation awarded to a University at Buffalo neurobiologist.

Lipids in the brain an important factor for Alzheimer's disease

As the most common form of dementia in the Western world, Alzheimer's disease carries enormous implications for our ageing society.

Hypertension associated with risk for mild cognitive impairment

High blood pressure appears to be associated with an increased risk for mild cognitive impairment, a condition that involves difficulties with thinking and learning, according to a report in the December issue of Archives of Neurology.

Older brains out of sync - memory and reasoning impaired

According to new research from the U.S., as people get older communication between different regions of the brain breaks down.

Growing old can affect the higher-level brain systems that govern cognition

A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.
