In the Gothenburg POiNT cohort of 135 iNPH patients, shunt surgery was linked to large postoperative CSF biomarker increases, with GAP43 rising 2.92-fold.
- Why it matters: Reliable predictors of shunt response in idiopathic normal pressure hydrocephalus are lacking, and CSF biomarkers could clarify mechanisms and identify likely responders.
- What they did: Patients had lumbar CSF sampled 3.6 (SD 2.1) months before and 5.7 (SD 2.4) months after surgery, with adjusted correlation and regression testing against iNPH scale outcomes.
- The result: Postoperative changes in multiple biomarkers were associated with the extent of clinical improvement, while baseline levels showed limited predictive value; baseline MCP1 predicted overall improvement modestly (AUC 0.67).
