HMM: Change of heart? It may affect thinking and memory skills in middle age.

Subtle changes in the structure and the diastolic function of a person’s heart between early adulthood and middle age may be associated with a decline in thinking and memory skills. The research is published in the January 26, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology. The diastolic function of the heart is when it rests between beats and the chambers fill with blood. . . .

After adjusting for factors like age, sex and education, researchers found that a greater than average increase from early to middle adulthood in the weight of a person’s left ventricle was associated with lower midlife cognition on most tests.

This study doesn’t overwhelm me, but I hope they’ll look further.
