First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether etidronate, a drug used for bone disorders, can reduce calcium deposits in the brain and slow disease progression in Fahr's disease or syndrome. 98 adults will receive either etidronate or a placebo for 12 months. The study measures changes in thinking, memory, movement, and quality of life.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Etidronate (a bisphosphonate drug, similar to alendronate, used to reduce calcium buildup)

What this could lead to

If it works, this could point toward the first treatment to slow or stop brain calcification in Fahr's disease, potentially preserving cognitive and motor function.

What could go wrong

This is a small, early-phase trial (phase 2) with only 98 participants. Previous evidence comes from a small case series, so the drug may not prove effective or could have side effects.
