摘要Background and Rationale: Dementia after stroke/transient ischemic attack (TIA) could occur immediately or with a delayedonset. Patients who were cognitively intact initially have a high risk of developing dementia at a later stage. We aimed to investigate the risk factors and underlying etiology of delayed-onset poststroke dementia (PSD).

Methods: Stroke/TIA patients (n = 1,007) were recruited into the Chinese University of Hong Kong STroke Registry Investigating cognitive DEcline (CU-STRIDE) study with a follow-up annually for 5 years. We investigated the incidence of dementia per year, with dementia defined as having a Clinical Dementia Rating scale of ≥1. We studied the associations between baseline vascular, genetic, imaging risk factors, and recurrent stroke with delayedonset
PSD using a logistic regression model.

Results: Patients who developed dementia 3–6 months after stroke (n = 88) were excluded, as we aim to focus on those with delayed-onset PSD. After the 5-year study period, 235/919 subjects remained. The cumulative incident dementia cases were 132/919. The new incident dementia cases were as follow: 2.7% (Year 1), 1.7% (Year 2), 1.3% (Year 3), 1.0% (Year 4), and 1.3% (Year 5). Random forest was used in variable selection. Diabetes mellitus (OR = 2.2, 95% CI = 1.2 to 4.0, p = 0.015) and multiple lacunes (≥3) (OR = 3.2, 95% CI = 1.7 to 5.9, p < 0.001) were significant predictors of delayed-onset PSD, after adjustment for age and education. The presence of ApoE ε4 and recurrent stroke were not significant predictors of delayed-onset PSD.

Conclusion: Diabetes mellitus and multiple lacunes were significant predictors of delayed-onset PSD.
