Gait, falls, cognitive function, and health-related quality of life after shunt-treated idiopathic normal pressure hydrocephalus—a single-center study
Clinical Scorecard: Impact of Shunt Treatment on Gait, Fall Incidence, Cognitive Abilities, and Quality of Life in Patients with Idiopathic Normal Pressure Hydrocephalus: A Single-Center Investigation
At a Glance
Category
Detail
Condition
Idiopathic Normal Pressure Hydrocephalus (iNPH)
Key Mechanisms
Ventricular enlargement with moderately elevated lumbar CSF pressure causing gait disturbance, cognitive decline, and urinary incontinence
Target Population
Predominantly elderly patients aged 70–80 years with iNPH
Care Setting
Neurological care and surgical intervention at specialized centers (e.g., Karolinska University Hospital)
Key Highlights
iNPH presents with a classical triad: gait and balance disturbance, urinary incontinence, and cognitive decline, with gait disturbance as the cardinal symptom.
Ventriculoperitoneal shunt surgery significantly improves gait velocity, reduces number of steps, and decreases timed up and go test duration at 3 months post-operation.
Cognitive deficits in iNPH affect memory, visuospatial abilities, psychomotor speed, and executive function, impacting activities of daily living and health-related quality of life.
Guideline-Based Recommendations
Diagnosis
Diagnosis based on clinical triad symptoms combined with ventricular enlargement and CSF tap test evaluation.
Use of Timed Up and Go test (TUG) and 10-meter walk test (10MWT) to assess gait function.
Mini-Mental State Examination (MMSE) for cognitive status assessment.
EQ-5D-5L and EQ VAS for health-related quality of life evaluation.
Management
Primary treatment is CSF diversion via ventriculoperitoneal shunt surgery.
Adjustable shunt models are commonly used.
Consideration of comorbidities such as hypertension, cardiovascular disease, and diabetes in management.
Monitoring & Follow-up
Pre- and post-operative assessment of gait using TUG and 10MWT at baseline and 3 months post-surgery.
Cognitive function monitoring with MMSE pre- and post-surgery.
Tracking fall incidence before and after surgery.
Evaluation of health-related quality of life using EQ-5D-5L and EQ VAS.
Risks
Untreated iNPH is associated with a hazard ratio of 3.8 for early death.
Risk factors for iNPH include vascular comorbidities such as hypertension and diabetes.
Potential gait and balance impairment may increase fall risk pre-surgery.
Patient & Prescribing Data
118 patients with iNPH undergoing ventriculoperitoneal shunt surgery at Karolinska University Hospital (2016–2018), mean age 73.5 years, 56% male.
Post-surgical improvements include a 25% increase in median walking speed, significant reduction in TUG time, and decreased number of steps during walking tests, indicating enhanced gait and mobility.
Clinical Best Practices
Perform comprehensive preoperative evaluation including gait tests (TUG, 10MWT), cognitive assessment (MMSE), and quality of life measures (EQ-5D-5L, EQ VAS).
Use CSF tap test results to select patients for shunt surgery.
Schedule follow-up assessments at 3 months post-surgery to evaluate improvements in gait, cognition, falls, and quality of life.
Monitor and manage vascular comorbidities to optimize patient outcomes.
Document fall incidence systematically to assess risk reduction post-treatment.
