Long-term anxiety in spontaneous intracerebral hemorrhage survivors.

Background: Although anxiety is common in several neurological conditions, it has been poorly investigated after spontaneous intracerebral hemorrhage (ICH).

Aims: In consecutive ICH survivors, we assessed the long-term prevalence of anxiety and its clinical and radiological determinants.

Methods: Using the Hospital Anxiety and Depression Scale (HADS), we evaluated ICH survivors enrolled in the prospective, single-center Prognosis of Intracerebral Hemorrhage (PITCH) study. The prevalence of anxiety (defined as a HADS-anxiety subscale score >7) was evaluated at three time points (1-2, 3-5, and 6-8 years after ICH), along with neurological symptoms severity, functional disability, and cognitive impairment scores. Clinical and radiological characteristics associated with anxiety were evaluated in univariate and multivariable models.

Results: Of 560 patients with spontaneous ICH, 255 were alive 1 year later, 179 of whom completed the HADS questionnaire and were included in the study. Thirty-one patients (17%; 95% confidence interval (CI) = 12-23) had anxiety 1-2 years, 38 (27%; 95% CI = 19-34) 3-5 years, and 18 (21%; 95% CI = 12-30) 6-8 years after ICH. In patients with anxiety, the prevalence of associated depressive symptoms was 48% 1-2 years, 61% 3-5 years, and 56% 6-8 years after ICH. Among clinical and radiological baseline characteristics, only lobar ICH location was significantly associated with anxiety 1-2 years after ICH (odds ratio = 2.8; 95% CI = 1.2-6.5). Anxiety was not associated with concomitant neurological symptoms severity, functional disability, or cognitive impairment.

Conclusion: Anxiety is frequent in ICH survivors, often in association with depressive symptoms, even many years after the index event.
