Infants with a diagnosis other than NE following perinatal asphyxia causing the seizures were excluded.Main outcome measures Clinical characteristics, findings on cranial MRI performed within 8 days after birth and neurodevelopmental outcome assessed using the Griffiths Mental Development Scales at 18 months or Bayley Scales of Infant and Toddler Development–Third Edition at 2 years of age.Results 39 infants were included. All had abnormalities on MRI. Predominant white matter/watershed injury was the most common pattern of injury, 23 (59%). 7 (18%) infants had predominant basal ganglia/thalamus injury, 3 (8%) near total brain injury, 5 (13%) arterial ischaemic stroke, 1 (3%) an intraventricular haemorrhage. Adverse outcome was seen in 51%: 6 died, 11 developed cerebral palsy (spastic n=8, dyskinetic n=3), 2 had neurodevelopmental delay, 1 had severe hearing impairment.Conclusions All infants with documented perinatal asphyxia and seizure onset within 24 hours after birth who did not receive TH had abnormalities on MRI. 51% had an adverse outcome. Better methods for recognition of infants who might benefit from TH and careful neurodevelopmental follow-up are urgently needed.All data relevant to the study are included in the article or uploaded as supplementary information.
