Clinical characteristics and outcomes of perinatal stroke in Australia: Population-based longitudinal study.

Abstract
Aim: Perinatal stroke is one of the main causes of hemiplegia and seizure disorder. This study aimed to analyse the clinical characteristics and outcomes of perinatal stroke in a cohort of Australian children for its early detection.
Methods: A population-based prospective longitudinal study on perinatal stroke up to 2 years of age, was conducted from 2017 to 2019.
Results: Eighty-seven children with perinatal stroke included 79% (69/87) acute and 21% (18/87) presumed perinatal stroke. Seventy-four per cent (51/69) acute symptomatic perinatal strokes presented in the first 3 days of life and 78% (14/18) presumed perinatal strokes presented by 6 months of age. 62% had an arterial stroke, 29% had a venous stroke and 5% had a combined arterial and venous stroke. Unexpectedly, 35% (24/69) acute symptomatic perinatal stroke had only respiratory symptoms and 50% (9/18) presumed perinatal stroke were asymptomatic. The incidence of cerebral palsy was 29% (20/69) with acute symptomatic perinatal stroke and 72% (13/18) with presumed perinatal stroke.
Conclusions: The first week of a child’s life is the most critical period in terms of lifelong disability from perinatal stroke. Recognising diverse clinical presentations will ensure early diagnosis and timely intervention treatments.
