Brief Summary
This is a longitudinal single blind randomized trial to test the effects of high compared to low dose vitamin D3 supplementation on cognitive performance at 6 and 12 months, and MRI measures of 12 months duration. A cognitive assessment battery will be administered at baseline, 6 and 12 months. Related clinical data and information on depression and anxiety, lifestyle, and food sources of vitamin D and sun exposure among other variables will also be collected.

Outcome Measures
Primary Outcomes (8)
Change from Baseline Brief Visuospatial Memory Test-Revised (BVMT-R) scores at 6 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.
6 months
Change from Baseline Arabic Verbal Memory Test (VMAT) scores at 6 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.
6 months
Change from Baseline Symbol Digit Modalities Test (SDMT) scores at 6 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.
6 months
Change from Baseline Stroop test scores at 6 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.

low dose vitamin D3 supplementation
ACTIVE COMPARATORPatients in this group will take 800 IU daily dose of vitamin D supplementation. They will be kept on 800 IU for 6 months. If they still had low vitamin D at 3 months, they will be asked about their adherence to the supplement, the investigators will remind them to take it as prescribed, and the investigators will keep the 800 IU vitamin D supplement dose for another 3 months. If they were still deficient at 6 months, the investigators will switch them to 10,000 IU weekly dose.
high dose vitamin D3 supplementation
EXPERIMENTALPatients in this group will take 50,000 IU weekly dose of vitamin D supplementation. Patients who will reach normal serum vitamin D level, between 40-80 ng/ml, at 3 or 6 months will be asked to decrease their Vitamin D3 supplementation as follows: Those who will reach levels between 40-60ng/ml will be switched to 10,000 IU three times per week, and those who reach levels between 60-80 ng/ml will be switched to 10,000 IU once weekly. If they did not have any improvement in their levels of vitamin D at 3 or 6 months, they will be asked about their adherence to the supplement and the investigators will remind them to take it as prescribed and the investigators will keep them at the 50,000 IU weekly dose.
Interventions
At baseline, patients with deficient 25(OH)D levels will be randomly assigned 1:1 to receive either the high dose or standard dose vitamin D supplementation.
