Professional background

Dr Valeria Iodice is consultant in neurology and autonomic medicine and associate professor in neurology at University College London. Dr Iodice has been the clinical and academic lead of the autonomic unit at the National Hospital for Neurology and Neurosurgery, Queen Square, London since 2013.

She has longstanding clinical and research interests in autonomic neurology, gained in three worldwide autonomic centres: Mayo Clinic, Rochester USA; Imperial College London and The National Hospital for Neurology and Neurosurgery, London, UK.

Dr Iodice qualified at University Federico II, Medical College, Naples, Italy in 2003 and completed the residency in Neurology and Neurophysiology at the University Federico II, Naples, Italy in 2008.

She was awarded a clinical research fellowship in autonomic medicine at Mayo Clinic Rochester Minnesota (USA) in 2007 where she began her research on the autonomic nervous system (ANS) at the Autonomic Translational Centre, Mayo Clinic.

In 2009, she was award the first Sir Roger Bannister fellowship in autonomic disorders and was awarded with a PhD in neuroscience and autonomic neurology from Imperial College, London.

A respected speaker, she has presented at national and International meetings. Dr Iodice has written several publications in major specialist journals that focus on the ANS in neurology and cardiovascular disorders and chapters in international textbooks of neurological and cardiovascular medicine.

Research interests

Novel biomarkers for early diagnosis of autonomic disorders, pathophysiology and treatment of emerging diseases, including autoimmune autonomic disorders, alpha synucleinopathies, metabolic disorders, amyloidosis and hereditary autonomic neuropathies and postural tachycardia syndrome.
