Natural glucose byproduct prevents brain damage and cognitive impairment after diabetic coma

A natural, non-toxic byproduct of glucose may prevent brain cell death and cognitive impairment in diabetics following an episode of severely low blood sugar, according to researchers at the San Francisco VA Medical Center (SFVAMC).

Moderate alcohol consumption enhances the formation of new nerve cells

Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by Karolinska Institutet.

Gene therapy for Alzheimer's disease shows promise

In the first clinical trial of gene therapy for Alzheimer's disease researchers have produced preliminary evidence that gene therapy may slow the decline in mental functioning associated with Alzheimer's disease.

Substantially more effective therapy than current treatments for Alzheimer's disease

PET scans and cognitive tests have suggested that Alzheimer's disease patients with genetically modified tissue inserted directly into their brains show a reduction in the rate of cognitive decline and increased metabolic activity in the brain, according to a study published in the April 24, 2005 online issue of the journal Nature Medicine by researchers at the University of California, San Diego (UCSD) School of Medicine.

Important new finding about the brain and its stem cells

A family's bravery and generosity in the face of their son's death three years ago has enabled researchers to make an important new finding about the brain and its stem cells.

Gene may boost schizophrenia risk

Clues about how a suspect version of a gene may slightly increase risk for schizophrenia are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical.

Why people get drowsy and fall asleep, and how caffeine blocks that process

When cells in a certain part of the brain become overworked, a compound in the brain kicks in, telling them to shut down. This causes people to become drowsy and fall asleep. Alter that natural process by adding coffee or tea, and the brain compound – called adenosine – is blocked, and people stay awake.

Louder neurons drown out their quieter neighbors

As the brain develops, neurons reach out helter-skelter to form new connections, only a small number of which take hold. How the brain chooses which connections to keep and which to prune back appears to be governed by which branches have the most electrical activity-a finding that could help to explain how early experiences guide brain development.

Some Alzheimer’s patients can benefit from drug Memantine

The drug memantine can reduce cognitive deterioration and loss of everyday functions in patients with moderate to severe Alzheimer’s disease, according to a new review of studies.

Exercise variety - not intensity - appears to reduce some Alzheimer's disease risk

The variety of leisure and physical activity one engages in -- and not its intensity in terms of calories expended - may reduce dementia risk in older people, according to researchers at Johns Hopkins.

Unconventional wiring of the brain circuits that govern sleep and waking might explain the prevalence of insomnia

Unconventional wiring of the brain circuits that govern sleep and waking might explain the prevalence of insomnia and the condition's association with obesity, according to new work published in the April issue of Cell Metabolism. Characterized by a chronic inability to fall asleep or remain sleeping, insomnia is estimated to affect one in every eight Americans.

Eat your fruits and veggies - your body will thank you and your mother will be happy!

Eat your fruits and veggies - your body will thank you and your mother will be happy! And if that's not reason enough, a new study suggests antioxidant-rich fruits and vegetables may limit brain damage from stroke and other neurological disorders.

Breakdown in brain cell communication may contribute to the most common biochemical cause of mental retardation

The process is akin to a baseball game gone bad. Imagine if a pitcher were joined by six players simultaneously winding up on the mound. Crouched behind home plate, the single catcher would soon be overwhelmed. Even if the coach sent in teammates to catch the extra balls, confusion would reign on the field.

Ephrins may influence learning

A Burnham Institute study has found that one of the cell's largest families of signaling molecules, called ephrins, which are known to regulate the development of nerve cells, also controls nerve cells' ability to engulf critical chemicals and proteins for learning and memory.

Researchers shed light on the brain cell damage caused by Alzheimer's disease

The researchers hope that by gaining a better understanding of the disease's cellular impacts, progress can be made towards developing a treatment. The research is reported in the current edition of the Journal of Alzheimer's Disease, published by IOS publishers.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Step toward a potential treatment for Huntington's disease

Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntington's disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the disease.

Electroacupuncture can lower blood pressure

Dr. John C. Longhurst, director of the Susan Samueli Centre for Integrative Medicine at UC Irvine ,and researchers, have found that acupuncture using low levels of electrical stimulation can lower elevations in blood pressure by as much as 50 percent.

Solving sleep problems helps epileptic children

Sleeping woes may explain why children with epilepsy are often so hyperactive, say researchers with the University of Florida's Evelyn F. and William L. McKnight Brain Institute.

Medication that both stimulates appetite and reduces metabolic rate

Scientists at Oregon Health & Science University, in collaboration with Neurocrine Biosciences Inc., have successfully tested a research medication that both stimulates appetite and reduces metabolic rate in preclinical trials.
