Background and Objective: The main objective of our study was to detail the frequency and clinical determinants of poststroke generalized anxiety disorders in a large, well-defined stroke cohort. Methods: A total of 277 stroke patients aged 55–85 were subjected to a comprehensive psychiatric evaluation between 3 and 4 months after ischemic stroke. Primary generalized anxiety disorder or generalized anxiety disorder due to stroke were diagnosed according to DSM-IV symptom criteria. Results: The frequency of any generalized anxiety disorder was 20.6% (n = 57). According to a logistic model, any generalized anxiety disorder was associated with a history of epilepsy, comorbid depressive disorder, severity of depression, severity of anxiety, and the use of anxiolytic drugs. A discriminant analysis identified four factors that distinguished the two diagnostic subgroups from one another: the level of psychosocial functioning (worse score in patients with generalized anxiety due to stroke), a history of migraine, anterior circulation stroke localization (more frequent in patients with generalized anxiety disorder due to stroke), and a history of insomnia (more frequent in patients with primary generalized anxiety disorder). Conclusions: Clinically significant anxiety is common in ischemic stroke patients and may hamper their rehabilitation.
