Dr Steven Allder
Consultant NeurologistDr Allder’s main clinical focus is traumatic brain injury (TBI), and functional neurological disorders (FND). With respect to TBI, Dr Allder provides a clinical and medicolegal services for the assessment of patients with TBI across the whole spectrum of injury severity i.e moderate – severe to mild; and across diverse aetiologies of TBI i.e. civilian, sport’s and military.
Recognition Health, under Dr Allder’s clinical leadership, are completing a 4 years collaboration with the Aston Brain Centre looking at the clinical utility of Magnetoencephalography (MEG) in TBI, especially mTBI where MRI including DTI is normal. This has been a successful collaboration which will lead to the development of several improved diagnostic tools for mild TBI . The collaboration has also led to further projects across a wide spectrum of TBI aetiologies, engaging new partnerships with Nottingham University, Toronto Sick kids, and several commercial organisations.
Since 2020, Dr Allder and Recognition Health have developed a new primary academic collaboration with King’s College Hospital. This joint work is exploring two complementary areas. Firstly, the utility of more sophisticated MRI sequences to further enhance diagnostic and pathophysiological insights into mild TBI, especially sports related TBI. Secondly, we are exploring how deployment of state-of-the-art neuro-computational techniques can reveal the mechanisms underlying how structural injury from TBI creates the clinical profiles seen in these conditions. It is hoped this will lead to improved treatment strategies.
With respect to Functional Neurological Disorder Dr Allder has long standing interest and is a founding member of the FND Society. Dr Allder offers a clinical and medicolegal service for the assessment of patients with suspected FND. Dr Allder has a long-standing collaboration with Dr Leo Russell and Prof Allan Abbass, who are leading practitioners and researchers in a treatment modality for FND termed Intensive short-term dynamic psychotherapy (ISTDP). ISTDP is modality with a strong neuroscience rationale and empirical evidence base supporting its effectiveness. Dr Russell has recently joined Recognition Health and is working with Dr Allder to enhance our clinical offering for this patient group and extend research into the mechanisms by with this treatment modality creates improvements for patients
