A new study suggests that subtle reductions in the heart’s pumping ability may be linked to microscopic brain damage associated with memory decline, even before heart failure develops. Researchers found that people with weaker heart function showed greater tissue changes in memory-related brain regions several years later, and these changes were associated with poorer memory performance. While the study does not prove that heart problems directly cause cognitive decline or Alzheimer’s disease, it highlights the close connection between heart and brain health. Maintaining a heart-healthy lifestyle through regular exercise and cardiovascular care may also help protect long-term brain function.
