A recent prospective imaging study determined that the overall prevalence of older adults with cerebral cavernous malformation (CCM) is 0.46%. The findings and data from this study are important for determining the potential number of patients available for cohort studies and anticipated clinical trials in patients with CCM. Researchers included 4,721 participants aged 50 to 89 years who were enrolled between January 1, 2004, and December 15, 2015, in the Mayo Clinic Study of Aging, a longitudinal, population-based study. Participants were invited to undergo brain magnetic resonance imaging (MRI). Of total participants, 2,715 had an evaluable MRI. They found:
- Of total participants who underwent MRI scans, 12 (0.44%) had CCM.
- With the use of inverse probability weights to adjust for participation bias, the overall prevalence was 0.46%.
- The age-adjusted prevalence was found to be 0.61% for the 50- to 59-year age group, 0.17% for the 60- to 69-year age group, 0.45% for the 70- to 79-year age group, and 0.58% for the 80- to 89-year age group.
- The sex-adjusted prevalence was 0.41% for women and 0.51% for men.
