Cross-Lagged Relations Between Loneliness and Cognitive Performance in Daily Life Among Older Adults

Abstract

Loneliness affects 24-33% of older adults and has been associated with a 26% increased risk for developing Alzheimer’s Disease and related dementias (ADRDs). Given that ADRDs have a long preclinical period, loneliness may arise in response to earlier cognitive changes and act as a preclinical indicator.
