• Introduction The relationship between persistent loneliness and Alzheimer's disease (AD) is unclear. We examined the relationship between different types of mid‐life loneliness and the development of dementia and AD. Methods Loneliness was assessed in cognitively normal adults using one item from the Center for Epidemiologic Studies Depression Scale. We defined loneliness as no loneliness, transient loneliness, incident loneliness,or persistent loneliness, and applied Cox regression models and Kaplan‐Meier plots with dementia and AD as outcomes (n = 2880). Results After adjusting for demographics, social network, physical health, and apolipoprotein E ε4, persistent loneliness was associated with higher (hazard ratio [HR], 1.91; 95% confidence interval [CI] 1.25–2.90; P < .01), and transient loneliness with lower (HR, 0.34; 95% CI 0.14–0.84; P < .05), risk of dementia onset, compared to no loneliness. Results were similar for AD risk. Discussion Persistent loneliness in mid‐life is an independent risk factor for dementia and AD, whereas recovery from loneliness suggests resilience to dementia risk.
