Medical Notes this week…

            We reported last week on the opioid epidemic. Now a new study finds yet another symptom of opioid addiction—amnesia. The CDC’s Morbidity and Mortality Weekly Report describes a group of 14 patients—almost all opioid addicts–who couldn’t remember things they’d just been told. Along with short-term memory loss, the patients had abnormal MRI scans as well. Doctors are concerned the patients represent a new condition triggered by substance abuse that they were not previously aware of. Researchers say most of the patients recovered their normal memory after several months substance free.

            Sitting in traffic is a sure way to increase your stress level and a new study shows it also increases domestic violence. A study at Louisiana State University correlated 25 million traffic observations and two million police reports over four years and found that extreme traffic jams increase the likelihood of domestic violence when people get home by about 6 percent.

            People who’ve suffered concussions are held out of sports and school until they’re considered recovered but a new study shows that even then, they may have trouble driving. The study in the Journal of Neurotrauma tested the driving skills of 14 people who’d had a concussion but felt they were now over it. Researchers say that at times they drove as if they were drunk.

            And finally…parents who use threats and raised voices to get their kids to behave often end up doing the opposite. A study in the journal Child Development shows that kids parented harshly as ‘tweens are more likely to drop out of school, engage in early sex, and commit theft a few years later. Researchers say those kids reject their domineering parents and seek approval from their peers instead.

And that’s Medical Notes this week.
