Brief Summary

Multiple sclerosis (MS) is a chronic, inflammatory and disabling disease of the Cnetral Nervous System characterized by relapsing and / or progressive somatosensory, motor and vestibular clinical manifestations. Moreover, fatigue, depression, anxiety, and cognitive impairment are also present in most MS patients. These symptoms substantially impact quality of life and often show limited response to conventional pharmacological treatment. Transcranial direct current stimulation (tDCS) is a non-invasive technique that applies a weak direct current to the scalp via surface electrodes, modulating cortical excitability in a polarity-dependent manner. The objective of this study is to evaluate the efficacy and safety of tDCS for fatigue, depression, anxiety, and cognitive performance in patients with relapsing or progressive MS.

Outcome Measures

Primary Outcomes (4)

  • Modified Fatigue Impact Scale (MFIS) - Total Score

    The MFIS is a 21-item multidimensional self-report scale assessing the impact of fatigue on physical (9 items), cognitive (10 items), and psychosocial (2 items) functioning over the past 4 weeks. Each item is scored 0-4; total score ranges from 0 to 84. Higher scores indicate greater fatigue impact. The primary comparison is post-active-tDCS total score versus post-sham total score.

    Assessed at baseline (Day 0), immediately following the first 5-day stimulation block (Day 5), and immediately following the second 5-day stimulation block (Day 26 after washout)

  • Modified Fatigue Impact Scale (MFIS) - Physical Subscale

    Physical subscale of the MFIS (9 items; range 0-36). Assesses impact of fatigue on physical functioning. Compared between active tDCS and sham conditions.

    Baseline, Day 5, Day 26

  • Modified Fatigue Impact Scale (MFIS) - Cognitive Subscale

    Cognitive subscale of the MFIS (10 items; range 0-40). Assesses impact of fatigue on cognitive functioning. Compared between active tDCS and sham conditions.

    Baseline, Day 5, Day 26

  • Modified Fatigue Impact Scale (MFIS) - Psychosocial Subscale

    Psychosocial subscale of the MFIS (2 items; range 0-8). Assesses impact of fatigue on psychosocial functioning. Compared between active tDCS and sham conditions.

    Baseline, Day 5, Day 26

Secondary Outcomes (7)

  • Hospital Anxiety and Depression Scale (HADS) - Anxiety Subscale

    Baseline, Day 5, Day 26

  • Hospital Anxiety and Depression Scale (HADS) - Depression Subscale

    Baseline, Day 5, Day 26

  • Visual Analog Scale (VAS) - Fatigue

    Baseline, Day 5, Day 26

  • Visual Analog Scale (VAS) - Depression

    Baseline, Day 5, Day 26

  • Symbol Digit Modalities Test (SDMT)

    Baseline, Day 5, Day 26

  • +2 more secondary outcomes

Other Outcomes (1)

Interventions

Transcranial direct current stimulation (tDCS) is a non-invasive technique that applies a weak direct current to the scalp via surface electrodes, modulating cortical excitability in a polarity-dependent manner. tDCS has an established safety profile across the populations and protocols studied to date. This study uses an anodal stimulation montage of the dorsolateral prefrontal cortex (DLPFC).

You may qualify if:

  • Clinical diagnosis of Relapsing Multiple Sclerosis (RMS) or Progressive Multiple Sclerosis (PMS), with or without active progression, established per the 2014 McDonald diagnostic criteria
  • Expanded Disability Status Scale (EDSS) score of 0-3 at the time of screening
  • Time since initial MS diagnosis of at least 6 months
  • Active fatigue symptoms reported by the participant for at least the 6 months prior to enrollment

You may not qualify if:

  • History of neuropsychiatric illness (including major depression, bipolar disorder, schizophrenia, or any anxiety disorder) prior to the onset of multiple sclerosis
  • Diagnosis of neuromyelitis optica spectrum disorder (Devic's disease)
  • Presence of any other central nervous system disease
  • Disease duration greater than 10 years combined with an EDSS score of ≤ 2
  • Visual impairment secondary to optic neuritis, internuclear ophthalmoplegia (oculomotor disorder), or any other uncorrected visual impairment that would affect task performance on cognitive assessments
  • Current pharmacological treatment for fatigue or depression
  • Current neuropsychiatric pharmacological treatment, including any antidepressant, anxiolytic, neuroleptic, or anticonvulsant medication
