Patients with severe hydrocephalus and reduced cortical mass maintain normal cognitive function
the verdict
REFUTED
the evidence says no
confidence 11/100
Evidence consistently shows that severe hydrocephalus and reduced cortical mass are associated with measurable motor and cognitive deficits rather than normal cognitive function. Clinical and experimental studies demonstrate that ventricular enlargement leads to impairments that often improve following surgical intervention.
