050 - Metformin for Long-Covid, Aging Gracefully, and Loneliness - HealthHippieMD Week In Review

Metformin and Long Covid

A recent study published in The Lancet Infectious Diseases reveals that metformin, a commonly used diabetes drug, may reduce the risk of developing long COVID by 41 percent for individuals who are overweight or have obesity. Long COVID, a condition characterized by persistent symptoms after a COVID-19 infection, has no approved treatment. The study's findings offer hope, but further research is needed to validate the results and explore how metformin prevents long COVID. Although the mechanism is unclear, unlike the authors, who opine that metformin may interfere with viral replication, I think a more likely explanation is that it modulates the immune system through its influence on the microbiome.

How to Age Gracefully

A new study suggests that learning new skills can have significant cognitive benefits for older adults. The authors hypothesize that cognitive slowing as a senior is akin to the "summer slide" that schoolchildren experience (every year, teachers and parents observe how summer vacations lead some children's academic progress to backslide). What if the elderly experience a similar phenomenon? The research found that a three-month intervention program involving classes on various skills, such as singing, drawing, and language learning, improved participants' memory and attention. Surprisingly, the cognitive gains continued even after the program ended, with participants' abilities resembling those of individuals 30 years younger. Encouraging lifelong learning and creating enriched environments for older adults could enhance their cognitive skills and support healthy aging.
