The Research Roundup provides an overview of the past week’s research from Mayo Medical Laboratories consultants, including featured abstracts and complete list of published studies and reviews.
Cerebral microinfarcts are associated with increased risk of cognitive impairment and may have different risk factors than macroinfarcts. Subcortical microinfarcts are associated with declining blood pressure. Mayo Clinic researchers conducted a study to investigate blood pressure slopes as a risk factor for microinfarcts in elderly individuals. The study found the presence of cerebral microinfarcts using blood pressure slopes. Based on the results, subcortical microinfarcts were associated with declining blood pressure. Future studies should investigate whether declining blood pressure leads to subcortical microinfarcts or whether subcortical microinfarcts are a factor leading to declining blood pressure. The study was published in JAMA Neurology.
