[The German S3 guidelines on dementia]

Due to the demographic development, the number of dementia patients in Germany is continuously increasing. The complex care situation of those affected calls for meaningful guidelines. In 2008, the first S3 guideline on dementia was published, coordinated by the German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) and the German Association for Neurology (DGN) and accompanied by the Association of the Scientific Medical Societies in Germany (AWMF). An update was published in 2016. In recent years, the diagnostic possibilities for Alzheimer's disease, in particular, have greatly developed and a new disease concept has emerged that includes mild cognitive impairment (MCI) as part of the clinical manifestation of the disease and also enables the diagnosis of Alzheimer's disease in this phase. In the area of treatment, the first causal disease-modifying therapies will likely soon be available. Furthermore, epidemiological studies have also shown that up to 40% of the risks for dementia are dependent on modifiable risk factors, making prevention increasingly more important. In order to do justice to these developments a completely updated S3 guideline on dementia is currently being developed, which will be available digitally for the first time in the form of an app and which, in the sense of living guidelines, will enable rapid adjustments to progress in the future.
