Younger Age and Depressive Symptoms Predict High Risk of Generalized Anxiety After Stroke and Transient Ischemic Attack
Bibliographic record
Abstract
Background and Purpose— Depression and anxiety are common after stroke/transient ischemic attack (TIA). These conditions are associated with poor functional outcome and worse quality of life. However, few studies have explored predictors of poststroke risk of generalized anxiety, especially in patients without comorbid depressive symptoms. We aimed to explore predictors of high risk of generalized anxiety after stroke/TIA. Methods— Consecutive stroke and TIA referrals to the Sunnybrook Stroke Prevention Clinic over a 2-year period (April 2012–April 2014) who spoke English, were not severely aphasic, and who consented to complete neuropsychological testing were included in this analysis. Generalized anxiety and depressive symptoms were assessed using the Generalized Anxiety Disorder 7-item scale and Center for Epidemiological Studies Depression Scale, respectively. Results— Two hundred and fifty-eight patients completed the Generalized Anxiety Disorder 7-item scale, of whom 56 (22%) were at high risk for generalized anxiety (scores ≥10). Younger age (odds ratio=0.96; 95% CI, 0.93–0.99; P =0.004) and greater depressive symptoms (odds ratio=1.20; 95% CI, 1.14–1.26; P ≤0.001) were significant predictors of being at high risk for generalized anxiety after stroke/TIA. Younger patients (≤50 years) were significantly more likely to be at high risk for both depression and generalized anxiety than older patients (30% versus 12%, χ 2 [1, N=258]=10.98, P =0.001). Our model explained 56% of the variance in risk of generalized anxiety after stroke. In patients without severe depressive symptoms (n=193, 75%), age and severity of depressive symptoms remained the only factors associated with risk of generalized anxiety. Conclusions— Anxiety is common after stroke/TIA and is highly correlated with poststroke depressive symptoms and age, even among those without severe depressive symptoms. Given the greater frequency of both generalized anxiety and depressive symptoms in young survivors, routine screening for depression and further evaluation of anxiety after stroke/TIA is warranted.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
