New research on vitamin B and stroke patients

US researchers say that taking vitamin B daily still does not help prevent cognitive decline in people who have had a stroke or a temporary ischemic attack (TIA), according to UPI news agency.

Stroke is associated with an increased cognitive decline and degradation of cognitive functions such as memory and thinking.

Experts from the American Stroke Association have studied whether vitamin B can help prevent cognitive decline after a stroke.

More than 8,000 stroke survivors or transient ischemic patients were randomly given a vitamin B tablet containing 2mg of folic acid, 25mg B6 and 500 micrograms B12, or a placebo tablet each day.

About 2,200 patients performed a cognitive mental health test at the start of the study and every six months for an average of 2 years and 8 months.

The study did not show significant differences between cases of cognitive impairment among subjects taking vitamin B compared to placebo.
