Fig. 4From: Hyperdynamic CSF motion profiles found in idiopathic normal pressure hydrocephalus and Alzheimer’s disease assessed by fluid mechanics derived from magnetic resonance imagesBox plots of pressure gradients in the Sylvian aqueduct between AD patients, iNPH patients, and healthy elderly volunteers. Both the AD and iNPH groups had significantly greater pressure gradients compared to the volunteer group. AD Alzheimer’s disease, iNPH idiopathic normal pressure hydrocephalus outside values are indicated by a small “o”Back to article page
