Please assess the completion status of the following clinical trial:

Trial Title: Improving Cognitive Aptitudes With tDCS in Patients With Multiple Sclerosis

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* MS patients with relapsing remitting MS/secondary progression MS (based on the 2010 revised McDonald criteria)~* Cognitive deficits~* Motor deficits~Exclusion Criteria:~* contraindication to tDCS (seizure or epilepsy, metal in the head, ...)~* major psychiatric conditions or major depression~* coexisting instable medical condition~* substance or alcohol abuse~* regular intake of drug that strongly modulate brain excitability~* major sequels from MS preventing participation in the study~* pregnancy

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 65 Years
- Healthy Volunteers: t

Study Arms:
- real tDCS (Type: ACTIVE_COMPARATOR): Patients will receive non-invasive and painless brain stimulation over the rain areas involved in cognitive aptitudes.~tDCS will be applied during 20 minutes while patients will perform attentional, working memory and executive tasks
- Sham tDCS (Type: PLACEBO_COMPARATOR): this will be exactly as for real tDCS unless that the tDCS will be rapidly turned off, unbeknown from patients-therapist-examinator (double-blind trial)

Based on this trial design, predict the completion outcome and termination type (if applicable).
