Abstract
Objectives
To evaluate clinical response after external lumbar drainage (ELD) and ventriculoperitoneal shunting (VPS) in a cohort of patients with idiopathic normal pressure hydrocephalus associated with parkinsonism (iNPH-P), considering parkinsonism as clinical primary outcome.
Methods
Patients underwent long-term 72-h intracranial pressure-controlled CSF ELD. Clinical motor response before and after ELD was evaluated using changes in UPDRS-ME as outcome measure. A standardized cognitive assessment was also performed. iNPH-P patients who underwent VPS were clinically followed-up after surgery.
Results
Fourteen iNPH-P patients (age: 69.3 ± 11.6 years) were studied. The time of evaluation after ELD removal was 3.5 ± 1.8 days. We observed a significant motor improvement after the drainage in eight (57.1%) patients. Percent clinical motor response was 18.4 ± 6.7%. Twelve (85.7%) patients underwent VPS. Nine patients were examined after surgery at 31.6 ± 7 months. Four (44.4%) patients presented a clinically detectable improvement in motor response after VPS. No significant changes in cognitive performances were detected.
Conclusions
A clinically detectable motor response on parkinsonian signs was observed in a consistent part of iNPH-P patients few days after ELD as well as over two and half years after VPS. Parkinsonism should be considered as outcome measure for the clinical management of patients with iNPH-P.
