- Introduction. Undetermined strokes with an embolic pattern (USEP) represent a common phenotype. We assessed their frequency and compared USEP with cardioembolic stroke with a known source and non-cardioembolic stroke etiology. Methods. Study patients were 540 consecutive ischemic stroke patients admitted to Helsinki University Hospital with primary end-point of recurrent stroke in a 21-month follow-up. Cox regression adjusting for CHA(2)DS(2)-VASc and anticoagulation estimated the risk of USEP on recurrent stroke. Results. A total of 229 (42.4%) patients had a non-cardioembolic stroke etiology, 184 (34.1%) had a cardioembolic stroke with a known source, and 127 (23.5%) were classified as USEP. USEP patients had less diabetes and prior TIA, with more severe symptoms than the non-cardioembolic stroke cases. They were younger, had fewer comorbidities, and less severe symptoms than the cardioembolic stroke patients. Cumulative risk of recurrent stroke was 10.0% (95% CI 4.1%-15.9%) for USEP, 5.0% (1.1%-8.9%) for cardioembolic strokes, and 5.0% (3.0%-7.0%) for non-cardioembolic strokes (P = 0.089). USEP associated with a higher risk of recurrent stroke compared to non-cardioembolic strokes (hazard ratio 2.36, 95% CI 1.02-5.47; P = 0.046) and cardioembolic stroke with a known source (1.83, 1.07-3.14; P = 0.028). Conclusions. Despite their younger age and more favorable risk factor profile compared with other phenotypes, USEP exhibited a high risk of stroke recurrence.

- Objectives Posterior location affects the clinical presentation and outcome of ischemic stroke, but little is known about occipital intracerebral hemorrhage (ICH). We studied non-traumatic occipital ICH phenotype, outcome, and post-ICH epilepsy. Materials and Methods Occipital ICH patients were retrospectively identified from the Helsinki ICH Study registry of 1013 consecutive ICH patients treated in our tertiary center in 2005-2010. They were compared to non-occipital ICH patients to evaluate the effect of location on functional outcome at discharge (dichotomized modified Rankin Scale, mRS), 3- and 12-month mortality, and incidence of epilepsy. Results We found 19 occipital ICH patients (5.3% of lobar and 1.9% of all ICH). Compared to non-occipital lobar ICHs, they were younger (median age 63 vs 71 years,P= .007) and had lower National Institutes of Health Stroke Scale on admission (1 vs 8,P< .001), smaller hematoma volume (6.3 vs 17.7 ML,P= .008), and more frequently structural etiology underlying the ICH (26% vs 7%,P= .01). Mortality at both 3 and 12 months was 6%, whereas 84% reached favorable outcome (mRS 0-2) at discharge. Occipital location was associated with favorable outcome at discharge in lobar ICH (OR 11.02, 95% CI 1.55-78.20). Incidence of post-ICH epilepsy (median follow-up 2.7 years) was 18%, equaling to that of non-occipital lobar ICH. Conclusions Occipital ICH patients are younger, have less severe clinical presentation, smaller hematoma volume, more often structural etiology, and better outcome than other ICH patients. They exhibit a similar risk of epilepsy as non-occipital ICHs.
