Northern Lights Neuroscience Symposium 2024, Meeting Abstracts, September 26–27, 2024

The Northern Lights Neuroscience Symposium 2024 "Expanding Spectrum of Common Dementia Disorders" was held in Hanasaari, Helsinki (Espoo), Finland on September 26-27, 2024. The meeting was jointly organised by the Scandinavian Neuropathological Society (chair Olivera Casar-Borota) and University of Helsinki. Drs. Liisa Myllykangas (chair), Olli Tynninen, Maria Gardberg and Tuomas Rauramaa made up the organising committee. The event brought together neuropathologists, clinicians and neuroscientists from nine different counties. In total, 91 people had registered for the meeting, and there were 29 abstracts. The keynote lectures on neuropathological and clinical aspects of new dementia entities such as LATE and PART as well as subtypes of AD and LBD, vascular and mixed patologies, were given by Irina Alafuzoff, Peter Nelson, David Wolk, Gabor Kovacs, Melissa Murray, Jacob Vogel, Liisa Myllykangas, Per Borghammer, Johannes Attems and Masafumi Ihara. The Patrick Sourander lecture "Investigating choroid plexus and cerebrospinal fluid roles and functions in neurologic disease" was presented by Maria Lehtinen from Harvard Medical School. Seven additional oral presentations (selected from submitted abstracts) were also given. The participants were highly appreciative of the meeting's top level scientific content and of the networking event, which included a Finnish sauna, a cruise in the Helsinki archipelago and a dinner in the center of Helsinki.
