Hanna Westergren

I work as a child neurologist at Astrid Lindgren's Children's Hospital in Stockholm, Sweden. I did my medical studies in Linköping and then moved to Östersund where I got my medical license and also did my internship in Paediatrics. After nine years in Östersund I continued with an internship in Neuropaediatrics in Stockholm and finnished in 2018. 

I defended my thesis on neonatal seizures and outcomes in April 2026. My research project included four sub-studies of which two were nationwide registry-based population-studies, one was a validation study of neurological variables including neonatal seizure diagnoses in the Swedish Neonatal Quality Register (SNQ), and one sub-study was a systematic review of electroencephalographically verified neonatal seizures and the outcomes post-neonatal epilepsy (PNE), cerebral palsy (CP), intellectual disability (ID), developmental delay (DD), autism, attention-deficit hyperactivity disorder (ADHD) and death. The other two sub-studies were population-based, matched observational studies where I investigate the risk of PNE after electroencephalographically verified neonatal seizures and what types of anti-seizures medications (ASM's) are being used during neonatal hospitalization and what proportions of neonates being discharged with ASM. The fourth sub-study aimed to study the the risk of CP, ID, DD, autism, ADHD and death after electroencephalographically verified neonatal seizures.
