Brain Cancer Risk: Family History Plays a Key Role.

A new study suggests that if you a family history of cancerous brain tumors, it may put you at a higher risk of developing the same kind of tumors.

In this study, published in the Sept. 23 issue of Neurology, the researchers examined the medical records and family histories of almost 1,401 people who had either astrocytomas (tumors in the brain or spinal cord) or glioblastomas that is considered a more aggressive kind of astrocytomas.

Autism Study, Dropped by US Researchers

CHICAGO – A government agency has quitted plans for a study related to the treatment of autism, that critics had called an unethical experiment on children.

The National Institute of Mental Health (NIMH) said that the study of the treatment, called chelation has been aborted. The agency has decided to test other possible therapies for autism and associated disorders, the statement said.

“There will be parents who are disappointed,” said Richard Nakamura, the scientific director of NIMH. “We recognize that for children there is a thread line for the risk-benefit ratio. You have to be pretty assured of the overall safety of the procedure.”

The study had been suspended because of safety matters, after another study published last year regarding a drug used in the treatment to permanent brain dysfunction in rats. Continue reading “Autism Study, Dropped by US Researchers”

Naturally Born Babies Have Better Mothers’ Response, American Study Suggests.

According to an American study, babies who born naturally get more mothers’ response to their cries than the Caesarean.

The researchers noticed more activity in brain areas that are related to emotions and motivation in the 12 new mothers who had a natural delivery.

The researchers from the Yale University say that those hormones that generate at the time of birth may be the key factor in this connection. The women who had elected to have a Caesarean were included in this study. Continue reading “Naturally Born Babies Have Better Mothers’ Response, American Study Suggests.”

Toronto Researchers Find Link Between Brain Chemistry and Seasonal Affective Disorder.

According to scientists, seasonal changes in brain chemistry cause winter blues in some people.

Seasonal affective disorder is related to lack of light exposure during short winter days and it often proves quite debilitating in some people.

The study shows that the condition may develop proteins that make mood-regulating chemical serotonin more active in the brain. Continue reading “Toronto Researchers Find Link Between Brain Chemistry and Seasonal Affective Disorder.”

Gene therapy may help to restore hearing, US scientists find.

According to US scientists, Gene therapy, which is likely to restore hearing in mice, may prove helpful in humans too.

The scientists found that gene transfer developed functioning hair cells that are considered essential for the inner ear to interpret sounds.

People who have normal hearing their cochlear hair cells can turn sound into electrical signals that are transmitted to the brain. If the cells are lost or damaged once, they

Once the cells are lost or damaged, they cannot be replaced naturally.

‘Eat fatty fish to prevent dementia’ Finnish researchers suggest

According to Finnish researchers, risk of dementia as well as of stroke considerably decrease by eating tuna and other fatty fish.

The lead author of the study, Jyrki Virtanen of the University of Kuopio in Finland told that ‘silent’ brain lesions that often become the cause of memory loss and dementia occurred less in those people who ate baked or broiled fish high in omega-3 fatty acids.

“The results of some previous studies have shown that fish and fish oil is helpful to avoid stroke, but this is the first study of its kind that examines the effects of fish on brain lesions in older people,” Virtanen further added.

Fish like salmon, mackerel sardines, herring and other foods like walnuts are rich with omega-3 fatty acids. These foods have also shown an anti-inflammatory effect and related to a lower risk of cardiovascular disease.
