Post Stroke Depression

Background: Depression and anxiety after stroke are common conditions that are likely to be neglected. Abnormal red blood cell (RBC) indices may be associated with neuropsychiatric disorders. However, the association of RBC indices with post-stroke depression (PSD) and poststroke anxiety (PSA) has not been sufficiently investigated. Methods: We aimed to investigate the trajectory of post-stroke depression and anxiety in our follow- up stroke clinic at 1, 3, and 6 months, and the association of RBC indices with these. One hundred and sixty-two patients with a new diagnosis of ischemic stroke were followed up at 1, 3, and 6 months, and underwent Patient Health Questionnaire-9 (PHQ-9) and the general anxiety disorder 7-item (GAD-7) questionnaire for evaluation of depression and anxiety, respectively. First, we used Kaplan-Meier analysis to investigate the accumulated incidences of post-stroke depression and post-stroke anxiety. Next, to explore the association of RBC indices with psychiatric disorders after an ischemic stroke attack, we adjusted for demographic and vascular risk factors using multivariate Cox regression analysis. Results: Of the 162 patients with new-onset of ischemic stroke, we found the accumulated incidence rates of PSD (1.2%, 17.9%, and 35.8%) and PSA (1.2%, 13.6%, and 15.4%) at 1, 3, and 6 months, respectively. The incident PSD and PSA increased 3 months after a stroke attack. Multivariate Cox regression analysis indicated independent positive associations between PSD risk and higher mean corpuscular volume (MCV) (OR=1.42, 95% CI=1.16-1.76), older age (OR=2.63, 95% CI=1.16-5.93), and a negative relationship between male sex (OR=0.95, 95% CI=0.91-0.99) and PSA. Conclusion: The risks of PSD and PSA increased substantially 3 months beyond stroke onset. Of the RBC indices, higher MCV, showed an independent positive association with PSD.

Antidepressant Use

Background: Post-stroke depression is common, yet little is known about factors associated with antidepressant use in this population Methods: Data from the multicenter, prospective Adherence eValuation After Ischemic stroke-Longitudinal (AVAIL) registry was used to identify patients with post-stroke depression and to describe factors associated with antidepressant use. The analysis was performed after 3 months in 1751 ischemic stroke patients who had been admitted to 97 hospitals nationwide; 12 month follow-up was available for 1637 patients. The Get with the Guidelines-Stroke database was used to collect baseline data. Patients were classified as depressed based on a self-report scale (the Patient Health Questionnaire-8; score range 0 to 24, score ≥10 indicating depression). Frequencies were compared with Pearson X 2 and unadjusted ORs were calculated. Results: The prevalence of post stroke depression was similar at 3 and 12 months (19% [331/1751] vs 17% [280/1637], respectively, p=0.17). Regardless of depression status, antidepressant use was higher at 12 months (16% [287/1751] vs 20% [334/1637], p=0.002). Antidepressant use was also higher at 12 months in depressed patients (25% [84/331] vs 35% [98/280], p=0.009). The odds of antidepressant use at 3 months was higher in women than men (OR 1.6, 95% CI 1.2-2.1), Whites vs. Blacks (OR 1.7, 95% CI 1.1-2.8), in patients with vs. without cognitive deficits (OR 1.6, 95% CI 1.2-2.1) and in those with more severe disabilities (mRS≥3 vs. mRS<3, OR 1.7, 95% CI 1.3-2.3). Use did not vary with educational level, marital status, living situation, medication insurance coverage, or stroke recurrence. Similar trends were present at 12 months, except with higher use in those with recurrent stroke or TIA (OR 2.1, 95% CI 1.4-3.1). Conclusion: Three-quarters of depressed stroke patients at 3-months and nearly two-thirds at 12 months were not receiving antidepressants. Regardless of depression status, utilization of antidepressants after 3 and 12 months varied based on gender, race/ethnicity, cognitive status, disability level, and after 12-months, stroke recurrence. The reasons for the apparent underuse of antidepressants in patients with prevalent post-stroke depression require further study.

Background and Purpose: The results regarding the independent association between homocysteine (Hcy) levels and post-stroke cognitive impairment (PSCI) were inconsistent. The effect of age on this association has yet to be explored. This study aims to determine the relationship between Hcy levels, age, and cognitive impairment in a post-stroke population.Methods: A total of 592 patients with acute ischemic stroke (AIS) completed follow-up. Serum Hcy levels were measured enzymatically by spectrophotometry within 24 h of admission. Cognitive function was evaluated by the Mini-Mental State Examination (MMSE) 1 month after stroke, and the scores ≤ 24 were considered as cognitive impairment. Our study was dichotomized into two groups by a cut-off of 65 years. Multivariate logistic regression models were used to determine the association between baseline Hcy levels and cognitive impairment.Results: According to the MMSE score, 317 (53.5%) patients had cognitive impairment. Patients with higher levels of Hcy were more prone to have cognitive impairment 1 month after stroke than patients with lower levels of Hcy (p &lt; 0.001). The optimal cut-off points of Hcy level (μmol/L) were (T1) ≤ 8, (T2) 8–12, and (T3) ≥ 12. After adjusting for confounding factors, the multivariate regression analysis showed that the third Hcy tertile was independently associated with cognitive impairment [odds ratio (OR) = 2.057, 95% confidence interval (CI) = 1.133–3.735, p = 0.018). A stronger association [T2 (OR = 2.266, 95% CI = 1.042–4.926, p = 0.039); T3 (OR =3.583, 95% CI = 1.456–8.818, p = 0.005)] was found in the younger group. However, the independent association was not confirmed in the older group.Conclusions: Elevated Hcy levels in the acute phase of ischemic stroke were independently associated with cognitive impairment in a post-stroke population. Furthermore, the association was age-dependent and more meaningful in a younger population aged below 65. So, Hcy levels in patients with stroke should be well-monitored, especially in younger patients.
