This meta-analysis evaluated the efficacy of cerebrospinal fluid (CSF) shunting in adults aged 60 and older with idiopathic normal pressure hydrocephalus (iNPH). Four randomized controlled trials involving 224 patients were analyzed. CSF shunting significantly improved gait velocity (SMD 0.73, 95% CI 0.45 to 1.01; P < 0.0001) and functional independence, although it also increased the incidence of positional headaches.
Key findings
- CSF shunting improved gait velocity with a standardized mean difference of 0.73.
- Functional independence increased with an odds ratio of 3.92.
- Positional headaches occurred more frequently with shunting, with an odds ratio of 5.62.
- Cognitive function showed improvement with a standardized mean difference of 0.37.
Why it matters
The findings suggest that CSF shunting can significantly enhance mobility and independence in elderly patients with iNPH, which is crucial for improving quality of life. However, clinicians must weigh these benefits against potential complications.
