Transcranial Direct Current Stimulation for Fatigue, Mood, and Cognition in Multiple Sclerosis
Transcranial Direct Current Stimulation for Fatigue, Mood, and Cognition in Multiple Sclerosis: A Randomized, Double-Blind, Sham-Controlled, Crossover Trial
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.

Experimental: Active, F3 anode, F4 cathode, 20 minutes, 4 mA, transcranial direct current stimulation
|
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).

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Modified Fatigue Impact Scale (MFIS) - Total Score
Prazo: 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)
|
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
Prazo: Baseline, Day 5, Day 26
|
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
Prazo: Baseline, Day 5, Day 26
|
Cognitive subscale of the MFIS (10 items; range 0-40).
