Yo-yo dieting and sugar-bingeing can lead to anxiety and withdrawal symptoms

In research that sheds light on the perils of yo-yo dieting and repeated bouts of sugar-bingeing, researchers from The Scripps Research Institute have shown in animal models that cycling between periods of eating sweet and regular-tasting food can activate the brain's stress system and generate overeating, anxiety, and withdrawal-like symptoms.

Protein synaptotagmin-IV helps maintain an efficient brain

The instruction manual for maintaining an efficient brain may soon include a section on synaptotagmin-IV (Syt-IV), a protein known to influence learning and memory, thanks to a study by University of Wisconsin-Madison researchers.

Poor sleep disturbs neuroendocrine control of appetite

Laboratory and epidemiological studies continue to show that sleep curtailment and/or decreased sleep quality can disturb neuroendocrine control of appetite, leading to overeating, and can decrease insulin and/or increase insulin resistance, both steps on the road to Type 2 diabetes.

Research finds a role for the GABA neurotransmitter in maintaining energy balance

Controlling body weight is a complicated process, as any frustrated dieter might attest. But as scientists continue to investigate the brain's intricate neurocircuitry and its role in maintaining energy balance, they are forming a clearer picture of the myriad events that lead to weight gain and weight loss.

Oxytocin may inhibit social phobia

Swedish and British scientists have shown using functional magnetic resonance imaging (fMRI) that the hormone oxytocin can inhibit feelings of anxiety in specific individuals. Their discovery might lead to a better understanding and the improved treatment of psychiatric affections in which people feel distressed when meeting others, such as in cases of autism and social phobia.

Rett syndrome gene found to be full of surprises

A study funded by the National Institutes of Health (NIH) has transformed scientists' understanding of Rett syndrome, a genetic disorder that causes autistic behavior and other disabling symptoms. Until now, scientists thought that the gene behind Rett syndrome was an "off" switch, or repressor, for other genes. But the new study, published today in Science, shows that it is an "on" switch for a startlingly large number of genes.

HDAC inhibitors show potential as therapeutic agents in treating alcoholism

Reshaping of the DNA scaffolding that supports and controls the expression of genes in the brain may play a major role in the alcohol withdrawal symptoms, particularly anxiety, that make it so difficult for alcoholics to stop using alcohol.
