Idiopathic normal pressure hydrocephalus (INPH) is a treatable neurological condition in older adults. Accurate diagnosis and careful management are key to successful treatment outcomes with ventricular shunting.

Area of Science:

  • Neurology
  • Neurosurgery

Background:

  • Idiopathic normal pressure hydrocephalus (INPH) is a treatable neurological disorder affecting older adults.
  • It presents with gait/balance disturbances, urinary incontinence, and cognitive decline, alongside enlarged cerebral ventricles.
  • Diagnosis is challenging due to varied symptoms and overlap with other age-related conditions.

Purpose of the Study:

  • To outline evidence-based consensus guidelines for the diagnosis and treatment of INPH.
  • To emphasize the importance of accurate diagnosis and prognostication for successful surgical outcomes.

Main Methods:

  • Clinical documentation of characteristic INPH symptoms.
  • Brain imaging showing nonobstructive ventricular enlargement disproportionate to cerebral atrophy.
  • Adjunct tests like cerebrospinal fluid removal via lumbar puncture or drain for diagnostic certainty and prognostication.

Main Results:

  • Gait and balance disturbances are the most common presenting symptoms.
  • Cerebrospinal fluid removal tests aid in diagnosis and predicting shunt response.
  • Accurate diagnosis and comprehensive patient management improve shunting success rates.

Conclusions:

  • INPH is a treatable condition in older adults requiring a systematic diagnostic approach.
  • Effective management involves accurate diagnosis, appropriate evaluation, and careful perioperative care for shunting.
  • Successful outcomes depend on precise diagnosis, surgical candidacy assessment, and meticulous patient management.
