Brain Injury
General Information
NEWS:
Delusions Associated With Consistent Pattern Of Brain Injury “Often bizarre in content and held with absolute certainty, delusions are pathologic beliefs that remain fixed despite clear evidence that they are incorrect. "Delusions are common problems in a variety of psychiatric and neurological disorders," said Dr. Devinsky. "Psychiatric disorders with delusions, for example- schizophrenia, have been proven to have functional and structural brain pathology. But now improved diagnostic techniques are allowing us to have increased identification of neurologic disorders among other patient populations with delusions." In the study, the author finds that most neurologic patients with delusions usually have lesions in the right hemisphere and/or bifrontal areas. For example, the neurological disorders of Confabulation (incorrect or distorted statements made without conscious effort to deceive), Capgras (the ability to consciously recognize familiar faces but not emotionally connect with them) and Prosopagnosia (patients who may fail to recognize spouses or their own face but generate an unconscious response to familiar faces) result from right sided lesions.”
Mild Traumatic Brain Injuries May Cause Transient, Persistent Symptoms After Injury “"This study provides reassurance for parents of kids who suffer first-time concussions because we can see that more often than not they recover fully within a short amount of time," lead author Keith Owen Yeates, PhD, from Nationwide Children's Hospital and Ohio State University College of Medicine in Columbus, said in a news release. "However, the study also shows that kids who are at risk because their concussions are more severe need to be monitored for a longer period of time as their symptoms may last longer." “
Natasha Richardson Dies of Epidural Hematoma “The dura is the membrane between the brain and the skull. If blood collects in the area in between, it presses harder and harder against the brain. Eventually it causes herniation: the whole brain shifts. "When something large makes the brain shift, the blood supply gets cut off and the whole brain dies," Flamm says. Flamm did not examine Richardson, and he is quick to note that his comments on her case are speculation based on media reports. But Flamm has treated many patients with similar case histories. "If someone has a significant-size epidural hematoma that you can see on a CAT scan, you would operate and remove it," he says. "Sometimes you see a smaller one, and I don't operate. But that is rare — I usually operate because of the potential for the brain moving and putting pressure on a vital structure." From media reports, Flamm speculates that Richardson was already brain dead by the time she reached a local hospital — well before she was flown to New York. Despite Richardson's death, Flamm notes that an epidural hematoma is not always fatal and may not even cause lasting brain damage. “
