Ms. Szenasi switched to the milk substitute after reading testimonials from other parents who said their autistic children's symptoms had improved - even disappeared - when dairy and wheat were eliminated from their diet.
The gut disorder is caused by gluten intolerance, and can lead to bone problems, infertility or bowel cancer.
The charity Coeliac UK says some of the 800 patients surveyed reported seeing their GP almost 30 times before being diagnosed.
But it says the condition can be easily detected by GPs using a quick and simple blood test.
People with coeliac disease can experience a range of symptoms, including as bloating, diarrhoea, chronic fatigue, breathlessness, depression and weight gain.
The study, published in the May issue of Alcoholism: Clinical and Experimental Research, found that women become alcohol dependent more quickly than men and that alcohol more severely impairs women's cognitive functioning including perceptual and visual planning and processing, working memory and motor control.
"Our studied showed that female alcoholics experience a greater decrement in cognitive and motor functions and sustain an accelerated decline in processing speed than males," said Barbara Flannery, Ph.D., research psychologist at RTI. "Our findings confirm and extend prior research that alcohol exerts more profound adverse effect more quickly on women compared to men."
That is the finding of a new Cornell study that excluded people who did not have such mental disorders as post-traumatic stress disorder (PTSD) or major depression. One of the first studies to look at the effects of trauma on the brains of healthy people, it is published in the May issue of the journal Emotion.
Dr. Winchester and colleagues found that preterm birth rates peaked when pesticides and nitrates measurements in surface water were highest (April-July) and were lowest when nitrates and pesticides were lowest (Aug.-Sept.).
More than 27 million U.S. live births were studied from 1996-2002. Preterm birth varied from a high of 12.03% in June to a low of 10.44% in September. The highest rate of prematurity occurred in May-June (11.91%) and the lowest for Aug-Sept (10.79%) regardless of maternal age, race, education, marital status, alcohol or cigarette use, or whether the mother was an urban, suburban or rural resident. Pesticide and nitrate levels in surface water were also highest in May-June and lowest in August - September, according to the U.S. Geological Survey.
Event structure perception was originally believed to be confined to our visual system, but new research shows that a similar process occurs when reading about everyday events as well.
Nicole Speer and her colleagues at Washington University examined event structure perception by having subjects read narratives about everyday activities while undergoing functional Magnetic Resonance Imaging (fMRI) to measure neural activity. The subjects were then invited back a few days later to reread these same narratives, this time without the fMRI scan. Instead, they were asked to divide the narrative where they believed one segment of narrative activity ended and another segment began.
"Our results suggest that losing weight through calorie cutting won't lead to increased disability in older women," said Jamehl Demons, M.D., lead investigator on a project evaluating the effects of weight loss on physical performance.
And even when some of the weight was regained, the women still came out ahead.
"It looks like they are better off than if they had never tried to lose weight," said Mary F. Lyles, M.D., lead investigator on an analysis exploring how dieting affected body composition.
The results of both projects - which are part of the larger Diet, Exercise and Metabolism in Older Women (DEMO) study - are being presented today (May 4) at the annual meeting of the American Geriatrics Society in Seattle.
Previous studies have shown that the time of day greatly affects human's reaction time (for a review, see Carrier & Monk, 2000). This performance decrement is constantly found during the night with its' lowest point in the early morning. This leads to the assumption that the time of day directly affects the speed of cognitive processing.
Daniel Bratzke at the University of Tuebingen wished to take these studies a bit further and figure out what makes our reaction time so slow during the wee hours. While many researchers have studied this, Bratzke focused on one of the three stages of human processing because he argues that measuring overall reaction time does not allow researchers to separate the effects of three different processing stages. Bratzke describes, for example, that the stage models of human performance assume at least three distinct processing stages: early perceptual, central decisional and late motor. He writes, "Given this widely accepted view, the question arises whether time of day affects all processing stages in general or one or more stages selectively."
