The reported incidence and risk factors mediating seizures in Alzheimer's disease (AD) have been extremely inconsistent and relevant data is lacking in Asia. We investigated the incidence rate and risk of seizures in AD and in a large, nationwide cohort from Han Chinese. A retrospective population-based study was conducted on the data from Taiwan's National Health Insurance Research Database from 2000 to 2010. To reduce selection bias, we applied propensity scores, wherein 981 patients with AD were matched to 3835 non-AD controls from a pool of 1000,000 randomly sampled cohort dataset. This approach was based on age, sex, comorbidities and previous brain conditions. Incidence rate, cumulative incidence and hazard ratios (HRs) were estimated. During the 10-year follow-up period (mean follow-up time, 4.02 years), 44 out of 937 AD patients (4.7%) developed seizures. The incidence rate in the AD …
