Brain diseases account for as much disease burden as cancers (16%) and cardiovascular diseases (10%) combined (Norwegian Brain Council, 2021, p.15). Norway does not have sufficient knowledge of the overall disease burden caused by brain diseases, because international and national health statistics on brain diseases are spread across different categories. However, calculations by the Global Burden of Disease Study indicate that the disease burden (Disability-Adjusted Life-Years or DALY) caused by brain diseases in Norway in 2021 amounted to 29% (Institute for Health Metrics and Evaluation (IHME), 2024; Ann Kristin Skrindo Knudsen, Henrik Peersen & Lars Jacob Stovner, personal communication, 30 March 2025). Years of Life Lost (YLL) as a result of brain diseases amounted to 22%, while Years Lived with Disability (YLD) amounted to 36% in Norway in 2021 (ibid.).
