A protein in the brain called BDNF plays a big role in how well we think, learn, and remember things.

Scientific Claim

Brain-derived neurotrophic factor (BDNF) is a key regulator of cognitive performance and brain health.

Assessment Explanation

The claim reflects a widely accepted scientific view cited in the literature, not original evidence. The language 'has emerged as' is appropriately descriptive and non-causal.

Narrative Review

The study shows that when BDNF levels drop as we age, our memory and brain function get worse, but when BDNF goes up—like with intermittent fasting—our brains work better, so BDNF is super important for keeping our minds sharp.

Similar Assertions

As people get older, their brain makes less of a helpful protein called BDNF, which can make it harder to remember things and learn new stuff, and may raise the chance of dementia.

In mice and rats, eating only at certain times of day (like skipping meals sometimes) seems to boost a brain protein that helps with memory and thinking.
