Medical Notes this week…
Folate, or vitamin b-9, is an essential nutrient, especially for pregnant women. Folic acid is often added to bread, flour, cereal, and pasta to help eliminate deficiencies. Now new research shows supplementation is more important than we thought, because once somebody is short on folate, the damage can’t be fixed. The study in the journal PNAS shows that folate deficiency triggers errors in chromosomes that are passed on as the cell divides. Once those changes occur, they’re permanent.
If you’ve ever fibbed to your doctor, you’re not alone. In fact, a study in the journal JAMA Network Open finds that between 60 and 80 percent of people are less than forthcoming to their doctors about things that could affect their health. People apparently want to avoid being judged or lectured by doctors… or sometimes, they’re simply too embarrassed to tell the truth.
Various forms of dementia are increasing… and now scientists have found that a single specific mutation in one gene can cause one of them. “Frontotemporal dementia” accounts for about 20 percent of all early-onset forms of the disease…. which can affect people as young as their 40’s. A study in the journal Translational Psychiatry has tracked down a single mutation as the cause… and researchers say the finding could be important for both treatment and in research on Alzheimer’s disease.
And finally… a new study shows that forcing kids to apologize usually backfires. The study in the journal Merrill-Palmer Quarterly finds that children who receive an insincere apology dislike the apologizing kid even more than they did before. Transgressors feel worse, too… and don’t learn to have empathy for their victim.
