Ringstad G, Vatnehol SAS, Eide PK.. Brain : a journal of neurology, 2017-10-01
Topic: Brain proteins, microglia and lab models
In idiopathic normal pressure hydrocephalus, we found delayed enhancement (P < 0.05) and decreased clearance of gadobutrol (P < 0.05) at the Sylvian fissure.

Key findings
- In idiopathic normal pressure hydrocephalus, we found delayed enhancement (P < 0.05) and decreased clearance of gadobutrol (P < 0.05) at the Sylvian fissure.
Why it matters
In people with idiopathic normal pressure hydrocephalus, this study found delayed enhancement and decreased clearance of gadobutrol at the Sylvian fissure. It reports a finding about fluid clearance in that condition, not a treatment, cure, or prevention for Alzheimer's disease.
