Prof Hedley Emsley

Professor Hedley Emsley is a Consultant Neurologist and expert witness at Lancashire Teaching Hospitals NHS Foundation Trust, where he specialises in stroke neurology, and is also Professor of Clinical Neuroscience at Lancaster University. His principal areas of clinical expertise include vascular neurology, stroke and transient ischaemic attack, cerebral small vessel disease, cerebral amyloid angiopathy, migraine, late-onset epilepsy, Parkinson's disease and a broad range of general neurological disorders.

Professor Emsley has extensive experience in the assessment, diagnosis and management of adults with both acute and chronic neurological conditions. His clinical practice focuses particularly on cerebrovascular disease, including complex stroke syndromes, intracranial venous thrombosis and young-onset stroke associated with cervical arterial dissection. Alongside his vascular neurology work, he regularly assesses and manages patients presenting with epilepsy, headaches, functional neurological disorders, peripheral nerve disorders, multiple sclerosis and memory disorders, delivering comprehensive neurological care across a wide spectrum of conditions.

His expertise is complemented by an active academic role as Professor of Clinical Neuroscience, supporting research, education and the translation of advances in neurological science into clinical practice. Professor Emsley has also contributed to the development of stroke and neurology services through leadership in service innovation, clinical guideline development and regional neurological care pathways. His combination of specialist vascular neurology expertise, broad general neurological practice and academic leadership establishes him as an authoritative clinician in the diagnosis and management of complex neurological disease. 

Professor Hedley Emsley has undertaken medico-legal practice since 2025, accepting instructions in both clinical negligence and personal injury claims. He prepares independent expert reports for claimant instructions, providing opinion on complex neurological conditions with particular emphasis on vascular neurology, stroke and cerebrovascular disease. His practice includes the preparation of screening, breach of duty, causation and condition and prognosis reports, offering solicitors clear, evidence-based opinions on liability and the neurological consequences of injury or illness.

Professor Emsley's medico-legal expertise is informed by his extensive clinical experience in stroke medicine and general neurology. He is particularly well placed to advise on cases involving cerebrovascular disease, transient ischaemic attack, cerebral small vessel disease, epilepsy, functional neurological disorders, Parkinson's disease, peripheral nerve disorders and complex neurological presentations. His specialist knowledge enables him to provide balanced, well-reasoned opinions on diagnosis, standards of care, causation and long-term neurological outcome, assisting solicitors in understanding complex neurological evidence and the clinical issues relevant to litigation. 

Professor Emsley's current clinical practice centres on the assessment, investigation and management of adults with complex neurological disorders, with a particular focus on vascular neurology and stroke. He has extensive experience diagnosing and treating patients with acute and chronic cerebrovascular disease, including transient ischaemic attack, cerebral small vessel disease, cerebral amyloid angiopathy, intracranial venous thrombosis and young-onset stroke associated with cervical arterial dissection. His work also encompasses the long-term management of patients with neurological conditions requiring ongoing specialist assessment and treatment.

Alongside his vascular neurology practice, Professor Emsley regularly evaluates patients with epilepsy, migraine and other headache disorders, Parkinson's disease, multiple sclerosis, functional neurological disorder, peripheral nerve disease and peripheral neuropathy, as well as individuals presenting with blackouts, memory disorders and subdural haemorrhage. His expertise is applied across the full diagnostic pathway, integrating detailed neurological assessment with clinical investigation to establish accurate diagnoses and guide evidence-based management.

A particular strength of his practice lies in the assessment of complex neurovascular presentations and neurological disorders with overlapping or multifactorial pathology. His combination of specialist stroke expertise and broad general neurological practice enables him to manage patients with both common and highly complex neurological conditions, providing comprehensive, patient-centred care informed by current evidence and advances in clinical neuroscience. 

Professor Emsley is Professor of Clinical Neuroscience at Lancaster University and has published more than 130 PubMed-indexed papers, with internationally recognised research focusing on stroke, cerebrovascular disease, neuroinflammation and neurodegenerative disorders. He leads and collaborates on major research programmes using advanced imaging and data-driven methodologies, and combines his research activity with teaching and academic leadership in clinical neuroscience.
