Background: Fibromyalgia is a syndrome of chronic pain and other symptoms and is associated with patient discomfort and other diseases. This nationwide matched-cohort population-based study aimed to investigate the association between fibromyalgia and the risk of developing dementia, and to clarify the association between fibromyalgia and dementia. Materials and Methods: A total of 41,612 patients of age >50 years with newly diagnosed fibromyalgia between January 1, and December 31, 2000 were selected from the National Health Insurance Research Database of Taiwan, along with 124,836 controls matched for sex and age. After adjusting for any confounding factors, Fine and Gray competing risk analysis was used to compare the risk of developing dementia during the 10 years of follow-up. Results: Of the study subjects, 1,704 from 41,612 fibromyalgia patients (21.23 per 1,000 person-years) developed dementia when compared to 4,419 from 124,836 controls (18.94 per 1,000 person-years). Fine and Gray competing risk analysis revealed that the study subjects were more likely to develop dementia (hazard ratio: 2.29, 95% CI: 2.16-2.42; P < 0.001). After adjusting for sex, age, monthly income, urbanization level, geographic region of residence and comorbidities the hazard ratio was 2.77 (95% CI: 2.61-2.95, P < 0.001). Fibromyalgia was associated with increased risk of all types of dementia in this study. Conclusion: The study subjects with fibromyalgia had a 2.77-fold risk of dementia in comparison to the control group. Therefore, further studies are needed to elucidate the underlying mechanisms of the association between fibromyalgia and the risk of dementia.

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.

Background Guillain-Barre syndrome (GBS) is a rare immune-related neurological disorder with high mortality and morbidity, but the comorbid psychiatric disorders garnered little attention in the GBS patients. This study aimed to investigate the association between GBS and the risk of developing psychiatric disorders. Methods: A total of 18,192 enrolled patients, with 4548 study subjects who had suffered GBS, and 13,644 controls matched for gender and age, from the Inpatient Dataset of 2000-2013 in Taiwan, and selected from the National Health Insurance Research Database (NHIRD). After adjusting for confounding factors, Cox proportional hazards analysis was used to compare the risk of developing psychiatric disorders during the 13 years of follow-up. Results: Of the study subjects, 471 (10.35%) developed psychiatric disorders when compared to 1023 (7.50%) in the control group. Fine and Gray's competing risk model analysis revealed that the study subjects were more likely to develop psychiatric disorders (crude hazard ratio [HR]: 4.281 (95% CI = 3.819-4.798, p < 0.001). After adjusting for gender, age, monthly income, urbanization level, geographic region, and comorbidities, the adjusted HR was 4.320 (95% CI = 3.852-4.842, p < 0.001). Dementia, depressive disorders, sleep disorders, and psychotic disorders predominate in these psychiatric disorders. Mechanical ventilation and hemodialysis are associated with a lower risk of dementia when compared to the control groups. Conclusions: Patients who suffered from GBS had a higher risk of developing psychiatric disorders, and this finding should act as a reminder to the clinicians that a regular psychiatric follow-up might well be needed for those patients.
