Vitamin K status and cognitive function in healthy older adults

I would think if we had any smart doctors or hospital administrators they would be using this to make sure the meals in the hospital post-stroke were cognitive friendly. Unless you are on Warfarin  and need to stay away from vitamin K.
But I can almost 100% guarantee that absolutely nothing will be done to help your stroke recovery in this regard. Because we have shit for stroke associations and lead-assed inertia for doctors and stroke centers.
But thats just my reasoned opinion, if you have some proof otherwise please respond.

Abstract 

Evidence is accumulating that vitamin K could have a role in cognition, especially in aging. Using data from the Québec Longitudinal Study on Nutrition and Successful Aging (NuAge), a cross-sectional analysis was conducted to examine the associations between vitamin K status, measured as serum phylloquinone concentrations, and performance in verbal and non-verbal episodic memory, executive functions, and speed of processing. The sample included 320 men and women aged 70 to 85 years who were free of cognitive impairment. After adjustment for covariates, higher serum phylloquinone concentration (log-transformed) was associated with better verbal episodic memory performances (F = 2.43, p = 0.048); specifically with the scores (Z-transformed) on the second (β = 0.47; 95% confidence interval [CI] = 0.13–0.82), third (β = 0.41; 95% CI = 0.06–0.75), and 20-minute delayed (β = 0.47; 95% CI = 0.12–0.82) free recall trials of the RL/RI-16 Free and Cued Recall Task. No associations were found with non-verbal episodic memory, executive functions, and speed of processing. Our study adds evidence to the possible role of vitamin K in cognition during aging, specifically in the consolidation of the memory trace.
