Scientific American (7/17, Yuhas) reports that a study published online July 16 in the journal Neurology reveals that even a mild traumatic brain injury (TBI) may affect brain matter and cognition. The study’s findings “hint that the contusions leave a lasting trace in the brain.”
The Fox News (7/17, Kwan) website reports that researchers arrived at that conclusion after “working with a group of 44 people with mild TBI, nine people with moderate TBI and a control group of 33 healthy” matched individuals to whom they “administered DTI scans within one week of injury,” along with “the Glasgow Coma Scale (GSC) test to measure cognition.”

HealthDay (7/17, Preidt) reports that according to a review recently published in the American Journal of Clinical Nutrition, “taking B vitamins does not slow age-related mental decline or prevent Alzheimer’s disease.” After analyzing “data on 22,000 people who took part in 11 clinical trials that examined the effect of B vitamins on mental abilities in older people,” researchers found that even though “taking B vitamins did lower homocysteine levels by about one-fourth, this reduction had no effect on thinking skills.”

The Los Angeles Times (7/17, Morin) reports in “Science Now” that according to a study published online July 16 in the journal Nicotine & Tobacco Research, “smoking and suicide may be more closely related than previously thought.”

HealthDay (7/17, Preidt) reports that the study found that “smoking may increase a person’s risk for suicide, but high cigarette taxes and smoking restrictions in public places lower that risk.” After analyzing “suicide rates across the United States between 1990 and 2004,” researchers found that “states that introduced higher taxes on cigarettes and stricter rules to limit smoking in public places saw suicide rates decline up to 15 percent, relative to the national average.”

FOX News Latino (7/11, del Castillo) reported that according to the American Psychiatric Association, “lack of access to mental health services is one of the most serious health problems in the Hispanic community.” Previous research “released by the APA in 2001 reported that as few as one in 11 Hispanics with mental health issues seek professional care.” Annelle Primm, MD, deputy medical director and director of the APA’s Division of Diversity and Health Equity, tied the lack of access partly to “a lack of insurance.”
