Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescriptionSource
PrimaryChange from Baseline Brief Visuospatial Memory Test-Revised (BVMT-R) scores at 6 months6 months
It is a visuospatial memory test that is comprised of three memory trials (10 seconds each) followed by delayed recall trial after 25 minutes. It has been widely used as a quick measure of memory at bedside and in MS patients. The minimum score on each trial is 0 and the maximum score on each trial is 12. Higher values represent a better outcome.
ClinicalTrials.gov
PrimaryChange from Baseline Arabic Verbal Memory Test (VMAT) scores at 6 months6 months
It is a verbal memory test. It consists of 45 words that are distributed among 3 lists (List A, List B, and a Recognition List). Lists A and B are each composed of 15 words belonging to 3 semantic categories: vegetables, animals, and stationary. The recognition list is composed 45 words that include homonyms, shared or related words and unrelated words with respect to the previous two lists. The VMAT is administered as follows: List A Immediate Free Recall (5 trials) - List B Immediate Free Recall Trial - List A Short Delay Free Recall Trial - List A Short Delay Cued Recall Trial - List A Long Delay Free Recall Trial - List A Long Delay Cued Recall Trial. After 25 minutes of the last trial, List A Delayed Recognition Trial is administered. For each trial, the minimum total score is 0 and the maximum total score is 15. Higher scores represent a better outcome. For each trial except the recognition trial, repeated and intrusive words are counted separately.

PrimaryChange from Baseline Symbol Digit Modalities Test (SDMT) scores at 6 months6 months
It is a known and widely used speed of processing test. Oral SDMT will be administered; it does not require translation and has been used in Lebanon before. It consists of one trial. The minimum total score is 0 and the maximum total score is 110. Higher scores represent a better outcome.

PrimaryChange from Baseline Stroop test scores at 6 months6 months
It is a highly established test of attention. Subject is given a list of colors in black ink to read (Stroop 1), then a list of colors in their corresponding ink color (Stroop 2), and then finally a list of colors with incongruent ink colors (Stroop 3), the participant is expected to read the word without being affected by interfering mismatching color. The number of words read in a minute (minus the errors) is the dependent measure and interference will be calculated using the following equation: Interference = Stroop 3 - \[(Stroop 1+Stroop 2)/2\]. For each of the 3 lists, the minimum total score is 0 and the maximum total score is 100. Higher scores represent a better outcome. For the interference, the minimum score is -100 and the maximum score is 0. Higher scores represent a better outcome.
