Slower growth of preterm infants linked to altered brain development

Slower growth of preterm infants linked to altered brain development

Jan. 16, 2013 — Preterm infants who grow more slowly as they approached what would have been their due dates also have slower development in an area of the brain called the cerebral cortex, report Canadian researchers in a new study published January 16 in Science Translational Medicine. The cerebral cortex is a two to four millimetre layer of cells that envelopes the top part of the brain and is involved in cognitive, behavioural, and motor processes Continue reading

New technique helps stroke victims communicate

New technique helps stroke victims communicate

Jan. 15, 2013 — Stroke victims affected with loss of speech caused by Broca’s aphasia have been shown to speak fluidly through the use of a process called “speech entrainment” developed by researchers at the University of South Carolina’s Arnold School of Public Health. Aphasia, a severe communication problem caused by damage to the brain’s left hemisphere and characterized by halting speech, occurs in about one-third of people who have a stroke and affects personal and professional relationships.

First oral drug for spinal cord injury improves movement in mice

First oral drug for spinal cord injury improves movement in mice

Jan. 8, 2013 — An experimental oral drug given to mice after a spinal cord injury was effective at improving limb movement after the injury, a new study shows. The compound efficiently crossed the blood-brain barrier, did not increase pain and showed no toxic effects to the animals. Continue reading

Pesticides and Parkinson’s: Further proof of a link uncovered

Pesticides and Parkinson’s: Further proof of a link uncovered

Jan. 3, 2013 — For several years, neurologists at UCLA have been building a case that a link exists between pesticides and Parkinson’s disease. To date, paraquat, maneb and ziram — common chemicals sprayed in California’s Central Valley and elsewhere — have been tied to increases in the disease, not only among farmworkers but in individuals who simply lived or worked near fields and likely inhaled drifting particles Continue reading
