TIME (7/18, Sifferlin) reports that research (7/18) published in Alcoholism: Clinical & Experimental Research suggests “that when people drink alcohol with energy drinks they have a stronger desire to keep drinking compared to people who just drank a vodka soda.” In the study, investigators “assigned 75 participants between the ages 18 and 30 to either just drink alcohol, or drink an alcohol and energy drink combination.”

Newsweek (7/18, Mejia) reports that study “participants were asked to take an Alcohol Urge Questionnaire 20 minutes before and after imbibing the libation to indicate how strong their desire was to continue drinking.” Individuals “who drank the alcohol and energy drink combo reported a greater increase in the urge to continue drinking alcohol than the group drinking only vodka.” Additionally, “the energy drink consumers…reported liking the cocktail more and wanting to drink more of it than those who only drank the vodka cocktail.”

Medscape (7/18, Jeffrey) reports that a study presented at the Alzheimer’s Association International Conference that surveyed “access to guns by patients with dementia finds that among consecutive patients being evaluated for cognitive problems, caregivers and family members did not consistently remove guns from their homes or keep them in a locked state.”

The study included 495 patients, 378 of whom had dementia, including Alzheimer’s. The study found that of participants “with a gun in the home, 62 (71%) had dementia; 33 (37%) had delusions, of which the majority (73%) were persecutory or paranoid delusions, and 15 (17%) had hallucinations, roughly half of which (47%) were hostile hallucinations.” The study authors recommended that physicians should ask about the presence of firearms during a patient visit.

USA Today (7/18, Zoroya) reports that a paper published online July 17 in the journal Current Psychiatric Reports has found “an indirect link between deployment, combat and self-destructive urges” among Afghanistan and Iraq veterans. The report concludes that “high rates of depression or post-traumatic stress disorder flowing out of the combat experience can lead to suicidal behavior.”

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.”
