We are pleased to present this month’s interesting paper, “Idiopathic Normal-Pressure Hydrocephalus” authored by:
Mark D Johnson, Michael A Williams
This review article highlights the significance of recognizing and treating idiopathic normal-pressure hydrocephalus, an often overlooked condition that can greatly impact the lives of those over 60. It emphasizes that timely diagnosis and surgical intervention can lead to significant improvements in cognitive function, mobility, and overall quality of life. By understanding this condition better, we can help dispel myths and promote effective treatment options for those who need it most.

Paper of the month – December 2025📑
We are pleased to present this month’s interesting paper, “Five-year outcomes after surgical treatment of infant postinfectious hydrocephalus in sub-Saharan Africa: results of a randomized trial” authored by: Edith Mbabazi-Kabachelor, Mallory R Peterson, John Mugamba, Peter Ssenyonga, Justin Onen, Esther Nalule, Joshua Magombe, VenkateswararaoCherukuri, Vishal Monga, Steven J Schiff, Abhaya V Kulkarni, Benjamin C Warf
This research on postinfectious hydrocephalus (PIH) in infants from Uganda addresses a critical public health issue in sub-Saharan Africa. Following a five-year follow-up of 100 infants, the study found that both endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) and ventriculoperitoneal shunt (VPS) provide comparable long-term outcomes in terms of brain growth, development, and quality of life. The strong correlation between brain volume and developmental metrics highlights the need for tailored interventions in this vulnerable group. This research not only enhances our understanding but also informs treatment strategies in resource-limited settings.
As the year comes to a close, we want to thank our members, colleagues,
and friends for an inspiring 2025. Wishing you a joyful holiday season and a healthy, successful 2026!

Paper of the month – November 2025📑
We are pleased to present this month’s interesting paper, “Neuro-ophthalmological findings in pediatric ventricular shunt failure: a systematic review” authored by: Soren Jonzzon MD, Anthony
Price MBA, Nina Truong BS, Robert P. Naftel MD, Paul H. Phillips MD, John C. Wellons III MD,
MSPH, and Albert M. Isaacs MD, PhD.
Key take-aways: • When a child’s ventriculoperitoneal shunt fails, one major danger is rising intracranial pressure.
• The review found that about 62% of children with surgically confirmed shunt failure showed
neuro-ophthalmologic findings such as optic disc swelling (papilledema), vision loss,
or eye movement/nerve palsies.
• After shunt revision surgery, most kids improved in disc swelling or nerve palsy (~80 – 90%), but unfortunately,
vision loss did not reliably improve.
• The authors suggest that checking for eye/vision signs should be part of how we evaluate shunt function,
not just brain scans and symptoms.

We are pleased to present this month’s interesting paper, “A Randomized Trial of Shunting for Idiopathic Normal-Pressure Hydrocephalus” authored by:
Mark G. Luciano, Michael A. Williams, Mark G. Hamilton, Heather L. Katzen, Nickolas A. Dasher, Abhay Moghekar, Jun Hua., Jan Malm, Anders Eklund, Naomi Alpert Abel, Ahmed M. Raslan, Benjamin D. Elder, Jesse J. Savage, Daniel L. Barrow, Kiarash Shahlaie, Hailey Jensen, M.Stat., Thomas J. Zwimpfer, Jessica Wollett, Daniel F. Hanley, and Richard Holubkov.
It refers to a double-blind, randomized, placebo-controlled trial involving participants selected for shunt surgery on the basis of gait-velocity improvement with cerebrospinal fluid (CSF) drainage.
Among participants with idiopathic normal-pressure hydrocephalus who had a response to temporary CSF drainage, shunting resulted in significant improvements at 3 months in gait velocity and a measure of gait and balance but not in measures of cognition or incontinence.
