Objective: The accurate prediction of the outcome after shunt implantation is the most important question in iNPH diagnostics. Due to this, the comorbidities are more and more of interest. In our study, we examined the influence of the comorbidities to the outcome of our patients.

Methods: We retrospectively analysed 100 patients in which we implanted a ventriculoperitoneal shunt with a gravitational valve due to an iNPH in our hospital between 9/1997 and 7/2005. We classified them with the Co-Morbidity-Index (CMI) introduced by Kiefer. The results were correlated with the outcome 12 months after surgery

Results: In patients with a CMI of 3 points or less the portion of shunt responders (excellent, good or satisfying outcome) were remarkebly higher than in patients with a CMI of more than 3 points.

Conclusions: The clinical success of shunt surgery correlates with the comorbidity. The CMI is a helpful tool for predicting the postoperative course of desease in patients with iNPH.
