Brain-computer interfaces (BCIs) offer promising applications for Multiple Sclerosis (MS) patients, particularly in rehabilitation, neural monitoring, and assistive technology. MS is a neurodegenerative disease affecting the central nervous system, causing motor impairments, cognitive dysfunction, and fatigue. BCIs can help address these challenges through neural interfaces that bypass damaged pathways[@wolpaw2020].
Multiple Sclerosis is characterized by autoimmune-mediated demyelination and axonal loss in the central nervous system. The disease affects approximately 2.8 million people worldwide, with symptoms ranging from mild sensory disturbances to severe motor disability. BCIs represent an emerging therapeutic approach that leverages neuroplasticity to restore function and improve quality of life[@wolpaw2020].

BCI Applications in MS
Motor Rehabilitation
BCI technology can assist MS patients with motor rehabilitation through multiple mechanisms[@buch2022]:
Neural Feedback for Movement Training: Patients receive real-time feedback on their motor imagery, helping them re-establish neural pathways between the brain and affected limbs
Brain-Controlled Prosthetic Devices: External devices can be controlled directly through neural signals, bypassing damaged motor pathways
Gait Training and Balance Restoration: BCI-coupled gait training systems help improve walking stability and reduce fall risk
Neuroplasticity Through Closed-Loop Stimulation: Combining motor imagery with peripheral stimulation enhances neural plasticity and motor recovery
Cognitive Assistance
MS often causes cognitive impairment affecting up to 65% of patients. BCIs can help address cognitive challenges[@stefano2021]:
Brain-Computer Interfaces for Communication: For patients with speech impairment (dysarthria), neural-based communication aids provide alternative expression methods
Neural Monitoring for Early Detection: Regular EEG monitoring can detect early cognitive changes before clinical symptoms worsen
Cognitive Training Through Neurofeedback: BCI-based neurofeedback can enhance attention, working memory, and processing speed
Memory Assistance: Neural信号-based memory aids may help compensate for memory deficits
Fatigue Management
MS-related fatigue is one of the most disabling symptoms, affecting up to 80% of patients. BCIs offer novel approaches to fatigue management[@stefano2021]:
Detecting Neural Patterns Associated with Fatigue: Machine learning algorithms can identify EEG signatures that precede fatigue onset
Real-Time Feedback for Energy Conservation: Wearable BCI systems can alert patients when mental fatigue is building
Optimizing Assistive Device Control: Reducing the cognitive load required to operate assistive devices
Rest-Activity Pattern Optimization: Neural monitoring can guide personalized rest schedules
Bladder and Autonomic Function
MS affects autonomic nervous system function. Emerging BCI applications include[@wolpaw2020]:
Bladder Control: Neural interfaces for managing neurogenic bladder
Blood Pressure Regulation: Monitoring and intervention for autonomic dysfunction
Temperature Regulation: Detecting and managing thermal dysregulation

Mechanistic Links to Neurodegeneration
Neurotrophic Factors
BCI-mediated rehabilitation may work through modulation of neurotrophic factors[@azin2023]:
BDNF: Brain-derived neurotrophic factor promotes neural plasticity and learning
GDNF: Glial cell line-derived neurotrophic factor supports oligodendrocyte function
Activity-Dependent Signaling: Motor training enhances growth factor expression
Neuroinflammation Pathways
MS involves chronic neuroinflammation mediated by:
Microglia: CNS immune cells that become activated in MS lesions
Pro-inflammatory Cytokines: IL-1β, TNF-α, and IL-6 contribute to demyelination
Vagal Tone Regulation: BCI neurofeedback may modulate inflammation through autonomic pathways
Excitotoxicity Mechanisms
Excitotoxicity via glutamate dysregulation contributes to MS progression[@azin2023]:
Glutamate Excitotoxicity: Excess glutamate damages oligodendrocytes and axons
Calcium Dysregulation: Intracellular calcium accumulation leads to cell death
NMDA Receptor Modulation: Some BCI approaches aim to normalize cortical excitability
Myelin Repair
BCI-assisted motor training may enhance myelin regeneration[@azin2023]:
