“…Weiner et al 2 state that SDHs occur in 20–40% of cases, shunted for NPH while Bergsneider et al 23 state that reported values of SDH range widely, from 2% to 17% and that a primary SDE might convert in the more serious SDH. According to Bloch and McDermott24 even with use of adjustable valves, modern INPH series have reported SDH rates as high as 10% with up to 7% requiring evacuation.…”

“…9,12,21,32,35,78,119 Studies show an improvement in neurocognitive measures after treatment, including verbal memory, psychomotor scores, mental tracking speed, attention, independent living, and caregiver scores. 62,77 Postshunting cognitive changes can precede functional recovery and may be sensitive and early markers of NPH outcome.…”

abbreviatioNs CPC = choroid plexus cauterization; DTI = diffusion tensor imaging; ETV = endoscopic third ventriculostomy; HCRN = Hydrocephalus Clinical Research Network; ICP = intracranial pressure; iNPH = idiopathic NPH; LPA = lysophosphatidic acid; NIH = National Institutes of Health; NPC = neural precursor cell; NPH = normal pressure hydrocephalus; NSC = neural stem cell; PreOL = precursor oligodendroglia; RCT = randomized controlled trial; SVZ = subventricular zone; TNF = tumor necrosis factor; VP = ventriculoperitoneal; VZ = ventricular zone. . International experts gave plenary talks, and extensive group discussions were held for each of the major themes.The conference emphasized patient-centered care and translational research, with the main objective to arrive at a consensus on priorities in hydrocephalus that have the potential to impact patient care in the next 5 years. The current state of hydrocephalus research and treatment was presented, and the following priorities for research were recommended for each theme. 1) Causes of Hydrocephalus-CSF absorption, production, and related drug therapies; pathogenesis of human hydrocephalus; improved animal and in vitro models of hydrocephalus; developmental and macromolecular transport mechanisms; biomechanical changes in hydrocephalus; and age-dependent mechanisms in the development of hydrocephalus. 2) Diagnosis of Hydrocephalus-implementation of a standardized set of protocols and a shared repository of technical information; prospective studies of multimodal techniques including MRI and CSF biomarkers to test potential pharmacological treatments; and quantitative and cost-effective CSF assessment techniques. 3) Treatment of Hydrocephalus-improved bioengineering efforts to reduce proximal catheter and overall shunt failure; external or implantable diagnostics and support for the biological infrastructure research that informs these efforts; and evidencebased surgical standardization with longitudinal metrics to validate or refute implemented practices, procedures, or tests. 4) Outcome in Hydrocephalus-development of specific, reliable batteries with metrics focused on the hydrocephalic 1427

“…When the patient is supine, the valve function depends on the lower pressure valve; when the patient stands vertically, CSF flow is directed by the combined resistance of the lower and higher pressure gravitational valve. We have demonstrated that the HV valve for LP shunting can be performed safely and may be associated with lower incidence of overdrainage phenomena (postural headache, subdural hygroma, hematoma, acquired Chiari malformation) [6]. We also demonstrated a parallel objective improvement in gait, urinary incontinence, and memory.…”
