INTRODUCTION: Our main objective was to investigate whether retinal neurodegeneration, estimated from lower thickness of inner retinal layers, was associated with incident all‐cause dementia and Alzheimer's disease (AD). METHODS: We performed an individual participant data meta‐analysis using unpublished data from four prospective cohort studies with a total of 69,955 participants (n = 1087 cases of incident all‐cause dementia; n = 520 cases incident AD; follow‐up time median [interquartile range] 11.3 [8.8–11.5] years). RESULTS: General baseline characteristics of the study population were mean (standard deviation) age, 58.1 (8.8) years; 47% women. After adjustment, lower baseline macular retinal nerve fiber layer thickness was significantly associated with a 10% and 11% higher incidence of all‐cause dementia and AD, respectively. Lower baseline macular ganglion cell‐inner plexiform layer thickness was not significantly associated with these outcomes. DISCUSSION: These findings suggest that retinal neurodegeneration precedes the onset of clinical dementia. Retinal imaging tools may be informative biomarkers for the study of the early pathophysiology of dementia. [ABSTRACT FROM AUTHOR] |
