Objective: Dietary magnesium may be associated with a lower risk of dementia; however, the impact of magnesium oxide (MgO), a common laxative, on dementia has yet to be elucidated. This study aimed to investigate the association between the usage of MgO and the risk of developing dementia. Methods: We used a dataset from the National Health Research Institute Database (NHRID) of Taiwan containing one million randomly sampled subjects to identify patients aged >= 50 years with no history of MgO usage. A total of 1547 patients who had used MgO were enrolled, along with 4641 controls who had not used the MgO propensity score matched by age, gender and comorbidity, at a ratio of 1:3. After adjusting for confounding risk factors, a Cox proportional hazards model was used to compare the risk of developing dementia during a 10 year follow-up period. Results: Of the enrolled patients, 44 (2.84%) developed dementia, when compared to 199 (4.28%) in the control group. The Cox proportional hazards regression analysis revealed that the patients who had used MgO were less likely to develop dementia with a crude hazard ratio of 0.617 (95% CI, 0.445-0.856, p=.004). After adjusting for age, gender, comorbidity, geographical area and urbanization level of residence, and monthly income, the adjusted hazard ratio was 0.517 (95% CI, 0.412-0.793, p=.001). Conclusions: The patients who used MgO had a decreased risk of developing dementia. Further studies on the effects of MgO in reducing the risk of dementia are therefore warranted.

Objective:This study aimed to investigate the association between adults with ADHD and the risk of developing dementia. Method: Utilizing National Health Insurance Research Database of Taiwan, ADHD patients were identified and compared with age- and gender-matched controls (1:3). Results: Of the study participants, 37 (5.48%) developed dementia compared with 81 (4.0%) in the control group. Cox proportional hazards regression analysis revealed that the study participants were more likely to develop dementia. The crude hazard ratio (HR) is 3.418 (95% confidence interval [CI] = [2.289, 5.106], p < .001), and adjusted HR is 4.008 (95% CI = [2.526, 6.361], p < .001) in risk of developing dementia after adjusted for age, gender, comorbidities, geographical area of residence, urbanization level of residence, and monthly income. Conclusion: Adults with ADHD have a 3.4-fold risk of developing dementia, and other large or national data sets should be explored to support the current findings.
