<jats:bold>Background and Purpose:</jats:bold>
Treatment with Selective Serotonin Reuptake Inhibitors (SSRIs) following acute ischemic stroke was shown to improve functional and motor recovery independently of depression, possibly mediated by long-term mechanisms such as increased brain plasticity. In animal studies, chronic SSRI treatment is superior over short-term SSRI in evoking neurogenesis but the applicability of this observation to humans remains unelucidated. We hypothesized that pre-treatment with SSRI in acute ischemic stroke patients is associated with improved recovery compared to post-stroke SSRI.

<jats:bold>Subjects and Methods:</jats:bold>
We performed an exploratory analysis in consecutive acute ischemic stroke patients who were pre-treated or treated de novo either with fluoxetine, citalopram or escitalopram. Effects of SSRI-pre-treatment on short-term clinical (total NIHSS and NIHSS motor items) and functional (mRS) outcome at discharge compared to post-stroke SSRI were assessed using bivariate and multivariate analyses.

<jats:bold>Results:</jats:bold>
Of 2653 patients screened, 239 were included (aged 69±14 years, mean±SD; 42% men, baseline median NIHSS 7 [IQR, 10]). Compared to post-stroke SSRI (n=188), in the SSRI pre-treatment group (n=51) favorable functional outcome at discharge (mRS≤2) was more frequent (41% vs. 20%; p=0.002), duration of hospitalization was shorter (median: 7 versus 11 days; p<0.0001), and there was a non-significant trend toward improved motor recovery (decrease in NIHSS motor items ≥2 points or 0-1 at discharge; 63% vs. 49%; p=0.08). However there was no such difference in total NIHSS recovery (≥4 points or 0-1 at discharge; p=n.s.). Pre-treatment with SSRI was an independent predictor of favorable functional outcome (mRS≤2) at discharge (OR: 4.00; 95%CI: 1.68-9.57; p=0.002) after adjusting for age, pre-stroke mRS, baseline NIHSS and IV-thrombolysis.

<jats:bold>Conclusions:</jats:bold>
Our data suggest that pre-treatment with SSRI may be linked to early clinical recovery after acute ischemic stroke and support the hypothesis that pre-stroke SSRI might be superior to post-stroke SSRI.
