Additionally, impaired cell proliferation in 2 neurogenic regions, the DG and the germinal matrix of the LV, has been described in postmortem brain from DS fetuses (Contestabile et al. 2007). These reports allow us to hypothesize that the hypoplasia of the adult DS brain may be related to developmental defects in the

      the movement of the fluid through the ventricles. This is called hydrocephalus. With this extra fluid, the ventricles may swell and push on the brain, possibly causing damage. IVH increases the risk of another kind of brain injury called periventricular leukomalacia (PVL). This happens when small areas of the brain near the ventricles are damaged.

However, a major diagnostic challenge remains to robustly identify shunt-responsive NPH patients from patients with enlarged ventricles due to other neurodegenerative diseases.
