Ultrasound Enhances Noninvasive Down Syndrome Tests

DNA clip art
ScienceDaily (Nov. 25, 2009) — The addition of a "genetic sonogram" maximizes the accuracy of non-invasive testing for Down syndrome, said a Baylor College of Medicine researcher who was lead author of a landmark study in the current issue of Obstetrics and Gynecology.

"We wanted to be able to definitively describe the detection and accuracy of noninvasive prenatal screening for the detection of Down syndrome," said Dr. Kjersti Aagaard, assistant professor of obstetrics and gynecology at BCM and the corresponding author of the report. "Using our data generated in the most comprehensive study performed to date (the FaSTER trial), we demonstrated that the addition of a genetic sonogram to all modes of screening in pregnancy allows for optimal noninvasive prenatal detection of Down syndrome." (FaSTER stands for First and Second Trimester Evaluation of Risk.)

Noninvasive screening for Down syndrome (as well as the other major fetal genetic or chromosomal abnormalities in the developing baby) involves a specific early ultrasound and series of tests for biochemicals in the mother's blood at particular times during pregnancy. Depending on the institution and clinic, tests are done during the first and/or second trimesters of pregnancy. Optimally, noninvasive screening also includes that a preliminary ultrasound to detect nuchal translucency takes place late in the first trimester. The test measures the clear or translucent space in the tissue at the back of the fetus' neck. If there is an abnormality, fluid will accumulate in the back of the neck making the nuchal fold area larger.

Certain Colors More Likely To Cause Epileptic Fits, Researchers Find

color pie clip artScienceDaily (Sep. 27, 2009) — Researchers have discovered that epileptic brains are more ordered than non-epileptic ones and also that certain flicking colors seem more likely to cause fits.

In 1997, more than seven hundred children in Japan reportedly suffered an epileptic attack while watching an episode of a popular cartoon. This was later diagnosed as a case of photosensitive epilepsy (a kind of epilepsy caused by visual stimulus) triggered by a specific segment of the cartoon containing a colorful flickering stimulus. Recently in 2007, the animated video footage promoting the 2012 London Olympics faced similar complaint from some viewers.

Because of the widespread usages of television and video games, it is important to detect the crucial visual parameters in triggering an epileptic attack. Common guidelines are available on specific visual parameters of the stimuli like spatial/temporal frequency, stimulus contrast, patterns etc. However, despite the ubiquitous presence of colorful displays and materials, very little is known about the relationship between color-combinations (chromaticity) and photosensitivity. Further it is also not precisely known how the patients' brain responses differ from healthy brains against such colorful stimuli.

The New York Times (November 24, 2009) -- Gregg Mozgala, a 31-year-old actor with cerebral palsy, had 12 years of physical therapy while he was growing up. But in the last eight months, a determined choreographer with an unconventional résumé has done what all those therapists could not: She has dramatically changed the way Mr. Mozgala walks.

In the process, she has changed his view of himself and of his possibilities.

Mr. Mozgala and the choreographer, Tamar Rogoff, have been working since last winter on a dance piece called “Diagnosis of a Faun.” It is to have its premiere on Dec. 3 at La MaMa Annex in the East Village, but the more important work of art may be what Ms. Rogoff has done to transform Mr. Mozgala’s body.

“I have felt things that I felt were completely closed off to me for the last 30 years,” he said. “The amount of sensation that comes through the work has been totally unexpected and is really quite wonderful.”

Cerebral palsy, a neurological disorder in which the brain does not send the proper signals to the muscles, affects gait and other movements. Those with severe cases use wheelchairs.

Mr. Mozgala’s condition is less severe but disruptive enough to have caused him to walk for most of his life like “a human velociraptor,” as he put it: up on his toes, lower extremities turned in, seesawing from side to side to maintain balance.

ScienceDaily (Nov. 23, 2009) — In a study that promises to improve diagnosis and monitoring of Alzheimer's disease, scientists at the University of California, San Diego have developed a fast and accurate method for quantifying subtle, sub-regional brain volume loss using magnetic resonance imaging (MRI).

The study will be published the week of November 16 in the Proceedings of the National Academy of Sciences (PNAS).

By applying the techniques to the newly completed dataset of the multi-institution Alzheimer's Disease Neuroimaging Initiative (ADNI), the scientists demonstrated that such sub-regional brain volume measurements outperform available measures for tracking severity of Alzheimer's disease, including widely used cognitive testing and measures of global brain-volume loss.

Explanation for Rapid Maturation of Neurons at Birth

(Credit: Image courtesy of Duke University Medical Center)

ScienceDaily (Nov. 20, 2009) — At the moment a newborn switches from amniotic fluid to breathing air, another profound shift occurs: nerve cells in the brain convert from hyperexcitability to a calm frame against which outside signals can be detected.

"Fetal neurons need hyperexcitability for proper development, because they are moving to the right places (in the brain) and forming the right connections," said Wolfgang Liedtke, M.D., Ph.D., assistant professor at the Duke Center for Translational Neuroscience and Klingenstein Fellow in Neuroscience. "But at birth, the brain has to undergo a developmental shift."

It does this by controlling a "pump" that drains chloride out of newborn neurons, making these highly chaotic, developing cells quiet down. Researchers at Duke University Medical Center have figured out the genetic control of the pump in rodents.

Scientists Solve Structure of NMDA Receptor Unit That Could Be Drug Target for Neurological Diseases

DNA clipart
ScienceDaily (Nov. 13, 2009) — A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer's, Parkinson's, and other serious illnesses.

Assistant Professor Hiro Furukawa, Ph.D., and colleagues at CSHL, in cooperation with the National Synchrotron Light Source at Brookhaven National Laboratory, obtained crystal structures for one of several "subunits" of the NMDA receptor. This receptor, formally called the N-methyl-D-aspartate receptor, belongs to a family of cellular receptors that mediate excitatory nerve transmission in the brain.

Excitatory signals represent the majority of nerve signals in most regions of the human brain. One theory of causation in Alzheimer's, Parkinson's and multiple sclerosis posits that excessive amounts of the excitatory neurotransmitter, glutamate, can cause an overstimulation of glutamate receptors, including the NMDA receptor. Such excitotoxicity, the theory holds, can cause nerve-cell death and subsequent neurological dysfunction.

ScienceDaily (Nov. 17, 2009) — Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin's receptor was linked to a person's ability to infer the mental state of others.

Interestingly, this same genetic variation also related to stress reactivity. These findings could have a significant impact in adding to the body of knowledge about the importance of oxytocin, and its link to conditions such as autism and unhealthy levels of stress.

Sarina Rodrigues, an assistant professor of psychology at Oregon State University, and Laura Saslow, a graduate student at the University of California, Berkeley, published their findings in the current issue of the Proceedings of the National Academy of Sciences (PNAS).

New Neuroimaging Analysis Technique Identifies Impact of Alzheimer's Disease Gene in Healthy Brains

brain clip art
ScienceDaily (Nov. 17, 2009) — Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. The results of this study are published in the Journal of Alzheimer's Disease.

Investigators used automated neuroimaging analysis techniques to characterize the impact of an AD-risk gene, apolipoprotein E (ApoE4), on gray and white matter in the brains of cognitively healthy elderly from the KU Brain Aging Project.

They found that healthy elderly individuals carrying a risk-allele of the ApoE4 gene had reduced cognitive performance, decreased brain volume in the hippocampus and amygdala (regions important for memory processing), and decreased white matter integrity in limbic regions. These type of brain changes are also found in people with AD. Therefore, brain changes, usually found in AD patients, are also evident in nondemented individuals who have a genetic risk of later developing AD.

Love and Envy Linked by Same Hormone, Oxytocin

Studies have shown that the oxytocin hormone has a positive effect on positive feelings. The hormone is released in the body naturally during childbirth and when engaging in sexual relations. (Credit: iStockphoto)

ScienceDaily (Nov. 13, 2009) — A new study carried out at the University of Haifa has found that the hormone oxytocin, the "love hormone," which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. "Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments," explains Simone Shamay-Tsoory who carried out the research.

Previous studies have shown that the oxytocin hormone has a positive effect on positive feelings. The hormone is released in the body naturally during childbirth and when engaging in sexual relations. Participants in an experiment who inhaled the synthetic form of the hormone displayed higher levels of altruistic feelings, and it is supposed that the hormone plays an important role in the formation of relationships between people.

However, in earlier studies carried out by other investigators with rodents, it was found that the hormone is also related to higher levels of aggression. Therefore, it was decided to examine whether the hormone also affects negative social sentiments.

Language Support In Schools Vital For Children With Autism

school clip art
ScienceDaily (Nov. 12, 2009) — Teachers and parents must be vigilant in observing difficulties with language comprehension, reading and spelling in children and young people with autism, Asperger's syndrome and ADHD. "It is important that pupils are offered the support to which they are entitled," says Jakob Åsberg in a new thesis at the University of Gothenburg.

Pupils with these neuropsychiatric disorders are often reported as having problems with spoken and written activities. However, relatively little research has been carried out within the field. Considering how important such skills are for coping independently in school and in working life and society in general, it is of great importance that we become better informed about these issues," considers Jakob Åsberg, who is publicly defending his thesis in psychology.

Theory About Long And Short-term Memory Challenged By New Research

brain clip artScienceDaily (Nov. 9, 2009) — The long-held theory that our brains use different mechanisms for forming long-term and short-term memories has been challenged by new research from UCL, published in PNAS.

Neuroscientists formed this theory based on observation of patients with amnesia, a condition that severely disrupts the ability to form long-lasting memories. Typically, amnesia is caused by injury to the hippocampi, a pair of brain structures located in the depth of the temporal lobes.

Despite the condition devastating long-term memory, such patients are quite proficient in rehearsing a phone number over short periods of time, as long as their attention is not distracted. This led to a hypothesis that the hippocampus supports long-term but not short-term memory. However, the UCL study shows that this distinction now needs to be reconsidered.

ScienceDaily (Nov. 10, 2009) —
The first human embryonic stem cell treatment approved by the FDA for human testing has been shown to restore limb function in rats with neck spinal cord injuries -- a finding that could expand the clinical trial to include people with cervical damage.

In January, the U.S. Food & Drug Administration gave Geron Corp. of Menlo Park, Calif., permission to test the UC Irvine treatment in individuals with thoracic spinal cord injuries, which occur below the neck. However, trying it in those with cervical damage wasn't approved because preclinical testing with rats hadn't been completed.

Results of the cervical study currently appear online in the journal Stem Cells. UCI scientist Hans Keirstead hopes the data will prompt the FDA to authorize clinical testing of the treatment in people with both types of spinal cord damage. About 52 percent of spinal cord injuries are cervical and 48 percent thoracic.

ScienceDaily (Nov. 11, 2009) — Autism affects an estimated 1 in 150 children today, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined. Despite its widespread effect, autism is not well understood and there are no objective medical tests to diagnose it. Recently, University of Missouri researchers have developed a pupil response test that is 92.5 percent accurate in separating children with autism from those with typical development. In the study, MU scientists found that children with autism have slower pupil responses to light change.

"No comprehensive study has been conducted previously to evaluate the pupils' responses to light change, or PLR, in children with autism," said Gang Yao, associate professor of biological engineering in the MU College of Agriculture, Food and Natural Resources and the College of Engineering. "In this study, we used a short light stimulus to induce pupil light reflexes in children under both dark and bright conditions. We found that children with autism showed significant differences in several PLR parameters compared to those with typical development."

ScienceDaily (Oct. 22, 2009) — The eyes may be the windows to the soul, but new research indicates they also may mirror a brain ravaged by Alzheimer's disease.

UC Irvine neuroscientists have found that retinas in mice genetically altered to have Alzheimer's undergo changes similar to those that occur in the brain -- most notably the accumulation of amyloid plaque lesions.

In addition, the scientists discovered that when Alzheimer's therapies are tested in such mice, retinal changes that result might predict how the treatments will work in humans better than changes in mouse brain tissue.

Sights And Sounds Of Emotion Trigger Big Brain Responses

ScienceDaily (Nov. 3, 2009) — Researchers at the University of York have identified a part of the brain that responds to both facial and vocal expressions of emotion.

They used the MagnetoEncephaloGraphic (MEG) scanner at the York Neuroimaging Centre to test responses in a region of the brain known as the posterior superior temporal sulcus.

The research team from the University's Department of Psychology and York Neuroimaging Centre found that the posterior superior temporal sulcus responds so strongly to a face plus a voice that it clearly has a 'multimodal' rather than an exclusively visual function. The research is published in the latest issue of Proceedings of the National Academy of Sciences (PNAS).

Neuroscientists Find Brain Region Responsible For Our Sense Of Personal Space

Patient SM, a woman with complete bilateral amygdala lesions (red), preferred to stand close to the experimenter (black). On average, control participants (blue) preferred to stand nearly twice as far away from the same experimenter. Images drawn to scale.

ScienceDaily (Aug. 31, 2009) — In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.

The discovery, described in the August 30 issue of the journal Nature Neuroscience, could offer insight into autism and other disorders where social distance is an issue.

The structure, the amygdala—a pair of almond-shaped regions located in the medial temporal lobes—was previously known to process strong negative emotions, such as anger and fear, and is considered the seat of emotion in the brain. However, it had never been linked rigorously to real-life human social interaction.

Report on the state of health care for persons with disabilities spotlights the effectiveness of the Rosebud Reservation Developmental Clinic in South Dakota.
A new report from the National Council on Disabilities, The Current State of Healthcare for People with Disabilities, cites a clinic serving the South Dakota Rosebud Reservation as an example of an effective program for children with developmental disabilities. The report's general findings concerning persons with intellectual and developmental disabilities point to disparities in health status, poor dental care, lack of needed health services, inadequate health care transition from childhood to adult care, and lack of adequate health care provider awareness and communication. Read the full report.

The National Institutes of Health (NIH) awards more than 50 autism research grants, totaling more than $65 million.
The 50 grants are the result of the largest-ever funding opportunity for research on autism spectrum disorders (ASD), which was announced in March 2009 and supported by the American Recovery and Reinvestment Act. The studies receiving awards "hold the best promise of revealing what causes autism, how it might be prevented, what treatments are effective, and how service needs change across the lifespan," said Thomas R. Insel, M.D., director of the National Institute of Mental Health and chair of the Interagency Autism Coordinating Committee. Selected studies range from discovering the specific genes underlying autism to developing a new tool to reduce screening costs to examining possible links between traffic-related pollution and ASD risk.

Study on Cardiovascular Risk Factors in Older People with Intellectual Disability Finds All Had Unhealthy Diet; Most Lacked Exercise and Were Overweight.
In a Dutch study published in the November 2009 issue of the American Journal on Intellectual and Developmental Disabilities, the authors evaluated the cardiovascular health of 470 individuals with intellectual disability ages 50-90 years old. Almost 100 percent of the participants had an unhealthy diet, and close to 70 percent lacked exercise and were overweight. Secondary conditions related to these factors, such as hypertension, diabetes, and hypercholesterolemia, afflicted a significant percentage of these individuals. The authors endorse campaigns to promote health, which are focused on education, and the introduction of preventive screening programs in this population. Read the final article.

Alzheimer's Researchers Find High Protein Diet Shrinks Brain

ScienceDaily (Oct. 21, 2009) — One of the many reasons to pick a low-calorie, low-fat diet rich in vegetables, fruits, and fish is that a host of epidemiological studies have suggested that such a diet may delay the onset or slow the progression of Alzheimer's disease (AD). Now a study published in BioMed Central's open access journal Molecular Neurodegeneration tests the effects of several diets, head-to-head, for their effects on AD pathology in a mouse model of the disease. Although the researchers were focused on triggers for brain plaque formation, they also found that, unexpectedly, a high protein diet apparently led to a smaller brain.

A research team from the US, Canada, and the UK tested four differing menus on transgenic mouse model of AD, which express a mutant form of the human amyloid precursor protein (APP). APP's role in the brain is not fully understood; however it is of great interest to AD researchers because the body uses it to generate the amyloid plaques typical of Alzheimer's. These mice were fed either
  • a regular diet,
  • a high fat/low carbohydrate custom diet,
  • a high protein/low carb version or
  • a high carbohydrate/low fat option.

No Scientific Link Between Childhood Vaccines And Autism, Review Shows

ScienceDaily (Oct. 10, 2009) — A new article recently published in the Journal for Specialists in Pediatric Nursing explored vaccination history, vaccine safety monitoring systems in the U.S., and the two most publicized theoretical vaccine-related exposures associated with autism – the vaccine preservative thimerosal and the measles, mumps, and rubella (MMR) vaccine. A review of published research shows that there is not convincing scientific evidence supporting a relationship between vaccines and autism. The article is part of a special issue, which includes five articles focusing on the topic of autism. By definition, the onset of autism occurs prior to age three. No clear cause of autism has been identified, although various possible

Does Diabetes Speed Up Memory Loss In Alzheimer's Disease?

ScienceDaily (Oct. 28, 2009) — Research has shown that diabetes increases the risk of Alzheimer's disease and the risk of memory loss in people who don't have Alzheimer's disease. But it hasn't been clear whether people with Alzheimer's disease and diabetes have more rapid memory loss than those who have Alzheimer's disease but no diabetes.

New research published in the October 27, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology, suggests that those with both diseases actually have a slower rate of memory loss than people who had only Alzheimer's disease.

"This result was surprising," said study author Caroline Sanz, MD, of INSERM, the French National Institute for Health and Medical Research in Toulouse. "Our initial hypothesis was that diabetes would increase the rate of cognitive decline in people with Alzheimer's disease."

Why Antidepressants Don't Work For So Many

ScienceDaily (Oct. 27, 2009) — More than half the people who take antidepressants for depression never get relief.

Why? Because the cause of depression has been oversimplified and drugs designed to treat it aim at the wrong target, according to new research from the Northwestern University Feinberg School of Medicine. The medications are like arrows shot at the outer rings of a bull's eye instead of the center.

A study from the laboratory of long-time depression researcher Eva Redei, presented at the Neuroscience 2009 conference in Chicago this week, appears to topple two strongly held beliefs about depression. One is that stressful life events are a major cause of depression. The other is that an imbalance in neurotransmitters in the brain triggers depressive symptoms.

ScienceDaily (Oct. 23, 2009) — Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. Whether a rare, whisper-small second set of cells also carry signals from the inner ear to the brain and have a real role in processing sound has been a matter of debate.

Now, reporting on rat experiments in the October 22 issue of Nature, a Johns Hopkins team says it has for what is believed to be the first time managed to measure and record the elusive electrical activity of the type II neurons in the snail-shell-like structure called the cochlea. And it turns out the cells do indeed carry signals from the ear to the brain, and the sounds they likely respond to would need to be loud, such as sirens or alarms that might be even be described as painful or traumatic.
