Area of Science:

  • Neuroscience
  • Economics
  • Public Health

Background:

  • Alzheimer's disease (AD) secondary prevention treatments are nearing clinical availability.
  • These treatments may preserve productivity in cognitively unimpaired individuals.
  • Estimating the labor market impact is crucial for assessing treatment value.

Purpose of the Study:

  • To estimate the economic influence of cognitive impairment on the US labor market.
  • To quantify the impact on workforce participation, earnings, and social assistance.

Main Methods:

  • Utilized longitudinal data from the Health and Retirement Study (1996-2020).
  • Compared labor market outcomes between incident cognitive impairment cases and matched cognitively normal individuals.
  • Analyzed data by gender for workforce participation, annual earnings, and social assistance payments.

Main Results:

  • Cognitive impairment reduced workforce participation by ~5 percentage points for both genders.
  • Annual earnings decreased by $4,466 (8.5%) for men and $1,574 (5.2%) for women.
  • Incident cognitive impairment increased social assistance receipt by 2.9-3.75 percentage points, implying an annual labor earnings loss of ~$896 million.

Conclusions:

  • Cognitive impairment onset leads to significant declines in workforce participation and income.
  • Increased reliance on social assistance programs was observed.
  • Treatments delaying the progression to prodromal Alzheimer's disease could generate substantial economic value.
