Abstract:
Objective:
The authors conducted a population-based investigation of mild behavioral impairment (MBI) in the Mayo Clinic Study of Aging setting. MBI refers to new onset of neuropsychiatric symptoms (NPS) among adults ages ≥50 that is not due to a psychiatric disorder and that may be a precursor of cognitive decline or dementia.
Methods:
The Neuropsychiatric Inventory Questionnaire was used in a cross-sectional study of participants ≥50 years without dementia to assess for NPS. Linear and logistic regression models were estimated and adjusted for age, sex, and education.
Results:
The study sample comprised 2,713 participants (mean±SD age=74.6±9.5 years, 47% women). Overall, 11% of the participants had MBI at the first follow-up; 2,498 were cognitively unimpaired (10% of whom had MBI), and 215 had mild cognitive impairment (MCI; 29% of whom had MBI). Having MBI was associated with significantly higher odds of MCI (OR=3.47, 95% CI=2.46–4.84) and lower cognitive scores. Severe MBI was associated with even higher MCI odds (OR=5.15, 95% CI=2.73–9.37) and lower cognitive scores.
Conclusions:
In this study of older adults, participants with MCI were almost three times more likely than cognitively unimpaired participants to have MBI. ... mehr
