Dr Luigi D’Argenzio

Dr Luigi D’Argenzio is a Consultant Paediatric Neurologist and expert witness at St George’s University Hospitals NHS Foundation Trust, where he has been in post since September 2021. His principal areas of expertise include paediatric epilepsy, hypoxic-ischaemic encephalopathy, traumatic brain injury, movement disorders, neuroinflammatory conditions and a broad range of acute and chronic neurological disorders affecting children.

Dr D’Argenzio provides specialist assessment, diagnosis and long-term management for infants, children and young people with complex neurological conditions. His current clinical practice encompasses the investigation and treatment of children with epilepsy, acquired brain injury, developmental and neuromuscular disorders, neuroinflammatory diseases and other complex neurological presentations, including the assessment and management of complications arising from these conditions. He is recognised for his comprehensive approach to evaluating challenging paediatric neurological cases and delivering evidence-based care across both acute and chronic settings.

Having trained in both Italy and the United Kingdom, Dr D’Argenzio has developed extensive experience within leading tertiary paediatric neuroscience centres before taking up his consultant appointment. His clinical expertise is further strengthened by research experience in paediatric neurology and neuromuscular disorders, together with a substantial publication record in the field. This combination of specialist clinical practice and academic involvement ensures he remains at the forefront of developments in paediatric neurology while delivering high-quality care to children with complex neurological needs.

Dr Luigi D’Argenzio has undertaken medico-legal work since 2020, accepting instructions in clinical negligence and personal injury claims. He acts for both claimant and defendant parties and has completed formal Bond Solon expert witness training in report writing, courtroom skills, cross-examination, and legal procedure, providing a strong foundation for high-quality medico-legal practice.

His medico-legal practice centres on paediatric neurology, with particular expertise in cases involving epilepsy, hypoxic-ischaemic encephalopathy, traumatic brain injury, movement disorders, neuroinflammatory conditions and other complex neurological disorders affecting children. He is instructed to provide screening, breach of duty, causation, and condition and prognosis reports, delivering clear, evidence-based opinions on the diagnosis, management and long-term neurological outcomes of paediatric patients. His specialist clinical expertise enables him to provide authoritative opinions across a broad spectrum of acute and chronic paediatric neurological conditions.

Dr D’Argenzio’s clinical practice is centred on the assessment, investigation and management of infants, children and young people with a wide spectrum of neurological disorders, from acute presentations to complex long-term conditions. He spends much of his clinical time diagnosing and treating children with epilepsy, including complex epilepsy syndromes, as well as caring for patients with hypoxic-ischaemic encephalopathy, traumatic brain injury and movement disorders.

He also has extensive experience managing children with neuroinflammatory and neuromuscular disorders, providing comprehensive neurological assessment and coordinating ongoing care for patients with multifaceted neurological needs. His practice frequently involves evaluating complex neurological presentations, identifying underlying causes of neurological symptoms and managing complications arising from both congenital and acquired neurological conditions. Drawing on both specialist clinical practice and academic research, he delivers evidence-based, patient-centred care while remaining actively engaged with advances in paediatric neuroscience. His expertise spans both acute neurological assessment and the long-term management of chronic neurological disease, enabling him to provide comprehensive care for children with complex neurological conditions. 

Dr D’Argenzio has an established academic background in paediatric neurology, underpinned by research fellowships in paediatric neurology and neuromuscular disorders. He has authored and co-authored numerous peer-reviewed publications spanning epilepsy, neuromuscular disease, neurogenetics and paediatric brain injury, reflecting a sustained contribution to advancing knowledge and evidence-based practice within paediatric neuroscience.
