How Blast Waves May Cause Human Brain Injury Even Without Direct Head Impacts

The Same Neural Networks In The Brain Process Familiar And Newly Learned Words

...Our vocabulary continues to grow and expand even in adulthood. Just ten years ago, the word 'blog' did not yet exist - and now we no longer remember when we heard this word for the first time or when we learned its meaning. At some stage new words become just as familiar to us as words we have learned earlier....

The Brain Predicts What Eyes In Motion Will See

...When the eyes move, objects in the line of sight suddenly jump to a different place on the retina, but the mind perceives the scene as stable and continuous. A new study reports that the brain predicts the consequences of eye movement even before the eyes take in a new scene. ...

Avian Flu Survivors At Increased Risk For Neurological Disorders Later In Life

Experts say that there is at least one strain of the H5N1 virus that leaves avian flu survivors at increased risk for Parkinson's disease, and other neurological problems later in life.

Take the Next Step after an ADHD Diagnosis.

... Behavioral therapy can help reduce problems related to the child's ability to pay attention or sit still at school, how he interacts with family and how well he does in his classes.Therapy should be started as soon as a diagnosis is made. ....Children with ADHD may not respond to the usual parenting practices, so experts recommend parent education.....Medication is one option that may help better control some of the behavior problems that have led to trouble in the past with family, friends and at school....
* Stimulants are the best-known and most widely used treatments. Between 70-80 percent of children with ADHD respond positively to these medications.
* Nonstimulants were approved for treating ADHD in 2003. This medication seems to have fewer side effects than stimulants and can last up to 24 hours....

Comments: Of course what they forget to mention is that children with ADHD can have vision problems and vision problems can mimic ADHD. Please have your child evaluated by an optometrist. DM

Design of a National Distributed Health Data Network

... A distributed health data network is a system that allows secure remote analysis of separate data sets, each comprising a different medical organization's or health plan's records. Distributed health data networks are currently being planned that could cover millions of people, permitting studies of comparative clinical effectiveness, best practices, diffusion of medical technologies, and quality of care. These networks could also support assessment of medical product safety and other public health needs. Distributed network technologies allow data holders to control all uses of their data, which overcomes many practical obstacles related to confidentiality, regulation, and proprietary interests. Some of the challenges and potential methods of operation of a multipurpose, multi-institutional distributed health data network are described....

Tips for Better Vision

Delleman Oorthuys syndrome: 'Oculocerebrocutaneous syndrome' Arora V, Kim UR, Khazei HM - Indian J Ophthalmol

Delleman Oorthuys syndrome: 'Oculocerebrocutaneous syndrome' Arora V, Kim UR, Khazei HM - Indian J Ophthalmol:

"Delleman Oorthuys syndrome (oculocerebrocutaneous syndrome) is a rare, congenital sporadic disorder affecting the skin and central nervous system. We present the case of a one-month-old male who presented with an orbital cyst in the left eye since birth along with other manifestations of this syndrome. The manifestations of this syndrome resemble other developmental disorders like Goldenhar and Goltz syndrome. Conservative management of the orbital cyst in these cases have been described. The need to diagnose this rare congenital anomaly with cerebral malformations as a separate entity is crucial in the management of these children."

Vision Screenings Unreliable

Wiley InterScience :: JOURNALS :: Journal of Nursing Scholarship: "Improvement in school vision-screening reliability is needed, especially among 6- and 7-year-old students. To this end, the determinants of fair reliability should be investigated and training programs planned. Reasons for differences in the reliability of nurses' recommendations detected among subdistricts must be further studied, together with careful supervision, to ensure better performance and adherence to PHS guidelines. Implications for nurses and nursing should be considered."

Comments: Vision screenings do not need improvement. They need to be discarded in favor of comprehensive eye and vision examinations for all children. DM

Common Causes For Childrens Headaches From Eye And Vsion Disorders

Neuroscientists Find Brain Region Responsible For Our Sense Of Personal Space

...Previous studies of humans never had revealed an association between the amygdala and personal space. From their knowledge of the literature, however, the researchers knew that monkeys with amygdala lesions preferred to stay in closer proximity to other monkeys and humans than did healthy monkeys....

Autism and vaccines: halo or horns for Dr. Andrew Wakefield

...Investigative reporter Brian Deer of the UK charges that everything about Dr. Andrew Wakefield's venture into the MMR vaccine controversy, simply "stank". Deer in fact, labeled Wakefield's involvement a "venture" in the true sense of the word. Apparently Wakefield was paid handsomely, (to the tune of three quarters of a million dollars) by a team of lawyers who hired him to testify in a class action suit against vaccine manufacturers. Wakefield was not an independent researcher, as originally portrayed. The attorneys representing families suing for vaccine injury, employed Wakefield to study the gastro issues of 12 specific children that were chosen by said attorneys. Wakefield determined that 11 out of the 12 autistic children had bowel disease, induced weeks after the MMR vaccination....

Researchers report gene associated with language, speech and reading disorders

...A new candidate gene for Specific Language Impairment has been identified by a research team directed by Mabel Rice at the University of Kansas, in collaboration with Shelley Smith, University of Nebraska Medical Center, and Javier Gayán of Neocodex, Seville, Spain. The finding, reported in the current issue of the Journal of Neurodevelopmental Disorders, was discovered by examining genes previously identified as candidate genes for reading impairments or speech sound disorders. The results point toward the likelihood of multiple genes contributing to language impairment, some of which also contribute to reading or speech impairment....

Comments: Remember....many genes need the environment before they can manifest a behavior, sign and/or symptom...DM

This is an ebook....I have not read it. If you get it let me know what you think! DM

Stereo Butterfly test appears reliable as adjunct to preschool vision screening

...The Stereo Butterfly test offered detection of strabismus in a group of children, a study showed. However, the test should be used in conjunction with other preschool screening protocols..."The Stereo Butterfly test may be a valuable adjunctive tool in vision screening programs for the detection of manifest strabismus because it is easy to administer and effectively detects constant strabismus," the authors said. "It has a high specificity for detection of constant strabismus but, if used alone, the low positive predictive value would allow for many false-positive results."...

Comments: All children should have full complete comprehsive eye exams...not screenings. Screenings miss too much. Aren't your children worth a comprehensive eye exam? DM

Esotropia, Acquired

...Esotropia is a type of strabismus or eye misalignment. The term is derived from 2 Greek words: ésò, meaning inward, and trépò, meaning turn. In esotropia, the eyes are crossed; that is, while one eye looks straight ahead, the other eye is turned in toward the nose. This inward deviation of the eyes can begin as early as infancy, later in childhood, or even into adulthood.

Acquired esotropia can occur after infancy and is not always responsive to farsighted glasses; because of this, it does not fall into the categories of congenital esotropia or accommodative esotropia, ...Although acquired esotropia can occur in patients aged 1-8 years, it typically develops in patients aged 2-5 years and appears to be infrequently associated with an underlying disease. ...

Comments: This was written by an OMD so they do not suggest vision therapy....but vision therapy should be conducted prior to any surgical intervention. DM
