A new study from the Swedish medical university Karolinska Institutet shows that infants with low concentrations of the stress-related hormone cortisol in their saliva develop fewer allergies than other infants. Hopefully this new knowledge will be useful in future allergy prevention. The study is published in the December paper issue of Journal of Allergy and […]
Imagine waking up and being unable to see or recognize anything on the left side of your body. This condition, called hemispatial neglect, is common after a stroke that occurs on the right side of the brain. The current treatment of attention and concentration training using computer and pencil-and-paper tasks is inadequate.
Potential clues to how autism miswires the brain are emerging from a study of a rare, purely genetic form of the disorders that affects fewer than 20 people worldwide. Using cutting-edge “disease-in a-dish” technology, researchers funded by the National Institutes of Health have grown patients’ skin cells into neurons to discover what goes wrong in […]
Patients who feel that their physicians treat them with respect and fairness, communicate well and engage with them outside of the office setting are more active in their own health care, finds a new study published in the journal Health Services Research. The study looked at how role relationships between patients and their physicians, which […]
Neuroscience researchers from Tufts have demonstrated, for the first time, that the physiological response to stress depends on neurosteroids acting on specific receptors in the brain, and they have been able to block that response in mice. This breakthrough suggests that these critical receptors may be drug therapy targets for control of the stress-response pathway. […]
Patients with Parkinson disease-related dementia appear to have increased brain atrophy in the hippocampal, temporal and parietal lobes and decreased prefrontal cortex volume compared to patients with Parkinson disease without dementia, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archivesjournals. The study was conducted by Daniel Weintraub, M.D., […]
A major study of recent international data on school mathematics performance casts doubt on some common assumptions about gender and math achievement — in particular, the idea that girls and women have less ability due to a difference in biology. “We tested some recently proposed hypotheses that try to explain a supposed gender gap in […]
Although there have been cardiovascular safety concerns about attention-deficit/hyperactivity disorder (ADHD) medications because of their ability to increase heart rate and blood pressure levels, an analysis that included more than 150,000 ADHD users found no evidence of an increased risk of heart attack, stroke, or sudden cardiac death associated with current use compared with non-use […]
