      abstract     = {A worldwide increase in dementia cases is expected due to
                      demographic changes and the growing elderly population.
                      However, recent studies suggest a declining incidence. This
                      analysis aimed to examine the trends in the incidence and
                      prevalence of diagnosed dementia in recent years based on
                      data from all individuals covered by statutory health
                      insurance in Germany.This study was based on claim data of
                      primary and specialist care practices (German population
                      coverage: $88\%)$ from 2015 to 2022. Individuals aged ≥65
                      years with a confirmed dementia diagnosis in at least two
                      out of four consecutive quarters were included. The
                      incidence and prevalence of dementia were age- and
                      sex-standardized calculated.The incidence decreased by
                      $26\%,$ from 2,020 per 100,000 insured individuals in 2015
                      to 1,500 per 100,000 insured individuals in 2022. The
                      prevalence decreased by $18\%$ during the same period, from
                      10,380 to 8,470 per 100,000 insured individuals. These
                      trends were more pronounced in younger age groups and among
                      women. The number of diagnosed dementia cases declined from
                      1.56 million in 2015 to 1.43 million in 2022, representing
                      an $8.4\%$ reduction.Despite ongoing demographic changes,
                      German primary and specialist care practices show a
                      significant decline in the incidence and prevalence of
                      diagnosed dementia cases, contrary to expected projections.
                      It remains an open research question whether a healthier
                      lifestyle, better education, and improved management of risk
                      factors by individuals or a reduced focus on dementia
                      diagnoses due to limited therapeutic options by physicians
                      have contributed to these trends. Further analyses of
                      long-term cohort studies are needed to validate these
                      findings.},
