To gauge the short- and long-term impacts of heart assault on the mind, Johansen’s group analyzed knowledge from greater than 31,000 Individuals who took half in six long-term research between 1971 and 2017.

When the contributors had their first evaluation of “cognitive” (pondering and reminiscence) abilities, their median age was 60 — that means half had been older, half youthful. That they had no historical past of coronary heart assault and had not been recognized with dementia.

“For too lengthy, we now have thought of and addressed heart disease and mind illness as two separate situations, and primarily based on our research’s findings and different analysis, I do not suppose we’re going to have the ability to maintain doing that as we be taught extra,” Johansen mentioned.
