AbstractBackground and PurposeDuring the coronavirus disease 2019 (COVID‐19) pandemic many countries reported a decline in stroke volumes. The aim of this study was to analyze if the decline was related to the intensity of the COVID‐19 pandemic.MethodsThe first pandemic year (1 March 2020 to 28 February 2021) overall and during the three COVID‐19 waves were compared with the preceding year. Volumes of acute ischaemic stroke (AIS), subarachnoid hemorrhage, intracerebral hemorrhage and recanalization treatments (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]) were obtained from the National Register of Reimbursed Health Services. Door‐to‐needle time, onset‐to‐door time and National Institutes of Health Stroke Scale at admission were obtained from the Registry of Stroke Care Quality.ResultsDuring the pandemic year compared to the preceding year there were 26,453 versus 28,771 stroke admissions, representing an 8.8% decline (p < 0.001). The declines (−10%, −11%, −19%) appeared in COVID‐19 waves (spring 2020, autumn 2020, winter 2021) except for an increase (2%) during summer 2020. Admissions for AIS declined by 10.2% (p < 0.001), whilst hemorrhagic stroke volumes were minimally decreased. The absolute volumes of IVT and MT decreased by 9.4% (p < 0.001) and 5.7% (p = 0.16), respectively. However, the proportions of ischaemic stroke patients receiving IVT (18% vs. 18%; p = 0.72) and MT (6% vs. 6%; p = 0.28) remained unchanged.ConclusionsThere was a decline in stroke admissions, but such decline was not related to COVID‐19 incidence. The frequency of use of recanalization procedures (IVT, MT) and times (onset‐to‐door time, door‐to‐needle time) in AIS were preserved in the Czech Republic during the first year of the pandemic.

Background & Purpose: Seizures are a recognized complication of stroke. However, available data are conflicting in terms of incidence, risk factors for occurrence, and impact on functional outcome and mortality. The aim of this study was to assess the incidence and characteristics of seizures following ischemic stroke in a well-defined population, and their effect on long-term patient outcome. Methodology: Utilizing the Rochester Epidemiology Project medical record linkage system, we identified all incident cases of ischemic stroke (IS) that occurred between January 1, 1990, and December 31, 1994. We identified all patients who developed seizures following first IS. Detailed data regarding stroke (including TOAST subtype, anatomic location, functional outcome), seizures (date, type, functional outcome, recurrence, presence of status epilepticus, complications, treatment, EEG findings), and patient status at the last follow-up were recorded and analyzed. Results: We identified 490 patients with first IS. Mean follow-up was 6.5 years (range 0.0 - 23.8). Of these, 35 (7.1%) developed seizures. Early seizures (occurring within 14 days of stroke) were present in 13 (37.1%), of which 9 (69.2%) had their seizure within the first 24 hours. Partial seizures were the most common type (23 patients, 65.7%). Status epilepticus occurred in two cases (5.7%). Tongue biting was the most common complication of poststroke seizures (4 patients, 11.4%). Treatment with antiepileptic drugs (AEDs) was initiated in 32 cases (91.4%). Only one drug was necessary for seizure control in all treated patients. The mean modified Rankin Scale score was 2.9 (SD 1.48) after the first IS, and worsened to 3.3 (SD 1.43) after the first seizure. Mortality at the last follow-up was higher in the seizure group compared to the non-seizure group, even after adjusting for TOAST subtype (HR 1.52; 95% CI 1.07 - 2.16; P = 0.02). Conclusion: Seizures are mostly a late complication of IS. They do not bear a high risk of life-threatening complications and are readily controllable by a single AED. However, patients who developed poststroke seizures tended to have a worse functional outcome and an increased mortality.
