The burden of cognitive impairment

The lifetime burden of cognitive impairment (CI) was estimated at $124,000 per capita, totaling $627 billion in aggregate-with 59% attributed to Alzheimer's disease and related dementias (ADRD) and 41% to mild cognitive impairment (MCI). Early-onset CI (before age 65) carried the highest per capita burden at $376,000, with these individuals living with MCI for about 13 years-over 7 years longer than those with late-onset CI. Significant disparities exist in CI burden, with racial/ethnic minorities and those without a high school degree experiencing disproportionately higher burden. Despite representing just 36% of the CI population, non-White individuals accounted for 47% of the aggregate CI burden.
