Area of Science:

  • Neurology
  • Neurosurgery
  • Epidemiology

Background:

  • Idiopathic normal-pressure hydrocephalus (INPH) lacks precise incidence/prevalence data.
  • Current diagnostic criteria for INPH are not evidence-based.
  • Accurate diagnosis is crucial for effective treatment and epidemiological studies.

Purpose of the Study:

  • To develop evidence-based clinical diagnostic criteria for INPH.
  • To facilitate future epidemiological research on INPH.
  • To promote earlier and more accurate diagnosis of INPH.

Main Methods:

  • Systematic review of medical literature (1966-2003) on normal-pressure hydrocephalus and INPH.
  • Inclusion of studies explicitly identifying INPH cases or diagnostic criteria.
  • Grading of evidence and supplementation with expert opinion for guideline development.

Main Results:

  • Developed evidence-based guidelines for INPH clinical diagnosis.
  • Established a framework for understanding INPH clinical manifestations.
  • Highlighted the importance of adhering to guidelines for timely and accurate recognition.

Conclusions:

  • Recommended classification of INPH into probable, possible, and unlikely categories.
  • Anticipated wider application of criteria in clinical practice.
  • Aimed to enhance consistency in patient selection for future INPH investigations.
