Is Grip Strength a Predictor of Long-Term Brain Health?

On today’s episode, Dr. Nick talks about the benefits of training grip strength for long-term brain health. Grip strength has been correlated with many health outcomes including all-cause and disease-specific mortality. Increased grip strength is associated with better bone mineral density, fewer falls and fractures, less depression and cognitive impairment, and improved quality of life. Because grip strength is usually similar to overall muscle strength, this becomes a good predictor for brain health. The brain also uses a lot of its real estate to control the hands for both precision and strength; therefore, appropriate grip strength shows proper brain function. A recent study even showed that higher grip strength correlated with more gray matter volume in the brain with improved mental health.

I had a hand injury a while ago, and one of the things I have had to work on regaining is my fine motor control. The correlation between grip strength and health is interesting because as my hands have recovered, *everything* I do with them feels better, which makes me feel better overall. I wonder if precision is also correlated with longevity, or even moreso, but it's harder to study. Because I think those precision muscles also go into producing a strong grip. BUT I'm not a doctor lol.

Please remember that correlation is not causation

Grip strength seems to be tied to neuromuscular strength and that is tied to nerve health. So if your body is able to repair and regenerate neurons, you'll also be able to use muscles more effectively.
