This review highlights advanced physiological measurements for diagnosing hydrocephalus, moving beyond traditional methods. It details techniques like intracranial pressure monitoring and cerebral blood flow studies for better patient management.

Area of Science:

  • Neurosurgery
  • Neurology
  • Medical Imaging

Background:

  • Hydrocephalus diagnosis traditionally relies on clinical assessment and brain imaging.
  • There's a growing recognition of physiological measurements in hydrocephalus management.
  • Recent guidelines emphasize improved diagnostic approaches for normal pressure hydrocephalus.

Purpose of the Study:

  • To review and discuss common physiological measurement methods for hydrocephalus diagnosis.
  • To explore techniques aiding in the assessment of cerebrospinal fluid (CSF) dynamics and intracranial pressure (ICP).
  • To provide clinical illustrations based on multidisciplinary expertise.

Main Methods:

  • Cerebrospinal fluid (CSF) infusion studies
  • Overnight intracranial pressure (ICP) monitoring
