Research

UC Irvine's Department of Neurological Surgery has active research activities and research protocols in normal pressure hydrocephalus, neuro-oncology and spinal cord injury.

Some current studies include:

Normal pressure hydrocephalus (NPH)

NPH is a difficult-to-diagnose disorder that occurs mainly in older adults and has three main symptoms: difficulty walking, or gait imbalance; urinary incontinence and memory problems.
Cranial scan

One of the most accurate ways to diagnose NPH is to drain small amounts of spinal fluid over the course of three days while the patient performs a series
of tests to examine their gait, cognition and ability to carry out general daily activities.

Patients whose symptoms improve after the spinal drainage have a good
chance for longer term improvement with a permanent brain shunt. Our study aims to determine which factors predict whether a patient improves with a shunt.

Intracranial pressure waveform analysis

This project, conducted in collaboration with the departments of Biomedical Engineering and Neurology, involves gathering data on patients being treated for a variety of conditions, including traumatic brain injury, intracerebral hemorrhage, stroke and subarachnoid hemorrhage.

Any patient who has a tube placed into the brain to monitor intracranial pressure (ICP) is eligible. Physiological data is recorded then analyzed with a sophisticated computer program. By analyzing the ICP waveform, we are working to develop a model that can predict dangerous ICP elevations before they occur and allow intervention in advance.

Brain tumor - Skull base lab 

Our faculty members also are active in many areas of basic and clinical research on brain tumors. Recent projects include:

  • Dennis Malkasian, MD, PhD, Director, Skull Base Lab - Educational focus primarily for training residents and post-graduate skull base fellows, a methodological approach. 
    • Post-graduate level lectures and cadaveraic dissections on classical and operative neuroanatomy, skull base anatomy, cervical and intracranial/extracranial surgical anatomy. 
    • Fundamentals of neurogenesis, morphogenesis, and general structural neural development. 
    • Relationship between ontogensis and oncogensis
