Cognitive improvement could be due to both Vitamin D and Rehab
1 )Test Vitamin D and Cognitive
2) 50,000 IU of vitamin D, once a week for eight weeks,
3) Maintenance therapy of 1,500–2,000 IU/d for additional 4 weeks
4) Test Vitamin D and Cognitive

Cognitive category starts with the following:

Very brief summary of Cognitive decline
Treatment : Vitamin D intervention slows or stops progression
Prevention : Many observational studies - perhaps Vitamin D prevents
Omega-3 both prevents and treats cognition
Wonder the benefits if both Vitamin D AND Omega-3 were to be used

Aim: Our aim was to determine whether there is a relationship between vitamin D [25(OH)D] and cognitive functioning in women with low 25(OH)D levels.

Methods: Ninety female patients, 25-45 years of age, who attended our outpatient clinic and had 25(OH)D levels < 30 ng/mL, were included. The Montreal Cognitive Assessment (MoCA) scale was used to determine cognitive functioning; the scale is divided into seven subgroups. Patients were divided into three subgroups according to their 25(OH)D levels. After a three-month period of 25(OH) D replacement, the patients underwent a re-evaluation using the MoCA scale.

Results: The total MoCA score before treatment was significantly different from the score after treatment (p < 0.05). Language and delayed recall functions were significantly different before and after treatment (p < 0.05).

Conclusion: Vitamin D levels were related to cognitive functioning in our study group.
