Lithium

A small lithium-carbonate trial reports a favorable functional measure. Its dementia-conversion result did not reach statistical significance.

A change in a laboratory marker, a test score and everyday function are different outcomes. A statistically detectable result does not by itself tell us whether someone would notice a worthwhile difference.

Check the measured endpoint, comparison and study population. The full profile preserves effect estimates and the source's clinical-significance assessment, including when that assessment is not supplied.

The claim to test: A disease-specific result establishes a healthy-aging benefit.

What the reviewed records say:

The gap: The longer follow-up had substantial attrition. Other studies and the companion safety paper still require review; findings do not establish lithium-orotate benefits.

Durability, effects in other populations and healthy-lifespan outcomes need their own evidence.

Independent replication, meaningful human outcomes, longer follow-up and better safety reporting would make these results easier to interpret.
