Highlight
1. Shunting significantly improves gait velocity and balance in selected patients with idiopathic normal-pressure hydrocephalus (iNPH) who show improvement after temporary CSF drainage.
2. No significant cognitive or urinary symptom improvements were observed at 3 months post-shunting.
3. Safety profile reveals more subdural bleeding and positional headaches in the shunted group, whereas falls were more frequent in the placebo group.
4. This trial provides high-quality evidence supporting shunt surgery in appropriately selected iNPH patients.
