Normal Pressure Hydrocephalus (NPH) is a neurological disorder characterized by gait disturbance, urinary incontinence, and cognitive decline—known as the triad—resulting from expanded cerebrospinal fluid (CSF) ventricles with normal opening pressure. NPH is particularly interesting for BCI applications because it is one of the few potentially reversible causes of dementia, and BCI can both support patients and potentially aid in treatment monitoring["@mori2023"].

Brain-Computer Interface for Normal Pressure Hydrocephalus
Overview
Mermaid diagram (expand to render)
Normal Pressure Hydrocephalus (NPH) is a neurological disorder characterized by gait disturbance, urinary incontinence, and cognitive decline—known as the triad—resulting from expanded cerebrospinal fluid (CSF) ventricles with normal opening pressure. NPH is particularly interesting for BCI applications because it is one of the few potentially reversible causes of dementia, and BCI can both support patients and potentially aid in treatment monitoring["@mori2023"].
Brain-computer interface technologies offer unique opportunities for NPH patients, who often present with a combination of motor, cognitive, and autonomic symptoms that respond differently to CSF diversion. The potentially reversible nature of NPH makes early BCI intervention particularly valuable for preventing irreversible damage["@hellstrom2022"].
Gait and Mobility Applications
Gait Rehabilitation BCI
Gait disturbance is typically the first and most responsive symptom in NPH:
Motor Imagery Systems
EEG-based motor imagery for gait pattern restoration
Neural-driven treadmill training for safe rehabilitation
Real-time gait phase detection for adaptive support
Biofeedback to improve stride length and cadence[@pereira2024]
Balance and Fall Prevention
Neural monitoring for fall risk assessment
Predictive algorithms for freezing of gait episodes
Auditory and haptic cueing triggered by neural states
Home-based monitoring systems for safety[@matsumoto2023]
CSF Pressure-Responsive Systems
The unique pathophysiology of NPH suggests potential for pressure-integrated BCI:
Closed-Loop Monitoring
Integration with intracranial pressure monitoring where available
Correlating neural states with CSF pressure fluctuations
Alert systems for pressure management
Treatment response tracking through neural [@czosnyka2023]
Cognitive Support Applications
Subcortical Cognitive Enhancement
NPH affects subcortical white matter pathways, impacting executive function and attention:
Executive Function Training
Neurofeedback targeting frontal lobe networks
Attention training using real-time neural monitoring
