Speaker presentations
Prof. Carsten Bjarkham, Aalborg University Hospital, Denmark
Carsten Reidies Bjarkam is senior consultant and professor in neurosurgery at Aalborg University Hospital Denmark. He is a subspecialized spine surgeon focusing on the use of minimal invasive nervous decompression techniques in the treatment of elderly patients with degenerative spine disease. He is a board member of the Scandinavian and the Danish Neurosurgical Societies, and he has for many years enjoyed teaching the coming generations of Scandinavian neurosurgeons at the yearly Beitostollen course in Norway.
Prof. Juhana Frösén, Tampere University
Juhana Frösén, Professor of Neurosurgery at Tampere University and University Hospital has studied the vascular biology of vessel remodeling for more than 25-years, translating this knowledge into major advances in our understanding of aneurysm formation, growth, and eventual rupture, as well as the formation, growth, and rupture of brain AVMs (arteriovenousmalformations). Prof. Frösen is most known for his work on the pathology of the intracranial aneurysm wall, and the association of aneurysm wall remodeling with inflammation and flow conditions. Prof. Frösén develops pharmaceutical therapy for intracranial aneurysms and bAVMs, in addition to treating these diseases microsurgically.
Together with a multidisciplinary team at the Tampere University, Prof. Frösén aims to develop data-driven and knowledge-driven decision support tools to help patients with intracranial aneurysms, bAVMs, or other cerebrovascular pathologies with hemorrhagic potential, to make informed decisions that are best for them.
In addition to working on improving predictive diagnostics, patient-centered decision-support tools, and the treatments of neurosurgical disease, developing the training of the next generation of neurosurgeons is close to the heart of Prof. Frösén.

Julia Lindlöf, University of Eastern Finland
Julia Lindlöf, RN, PhD, is a registered nurse and university teacher at the University of Eastern Finland. She has over ten years of clinical experience in neurosurgical nursing at the Department of Neurosurgery, Helsinki University Hospital, Finland.
In addition to her clinical and academic work, Lindlöf has worked as a project coordinator at the Finnish Brain Injury Association, focusing on improving support for family members of individuals with traumatic brain injury (TBI) during acute care.
Her doctoral dissertation, Empowering Support Framework for Family Members of Individuals with Traumatic Brain Injury – a mixed-methods study (2025), developed an Empowering Support Framework (ESF) to support family members in neurosurgical and neurological acute care settings and evaluated its applicability in nursing practice from the perspective of registered nurses.
