title: [Demographic change: Changes in society and medicine and developmental trends in geriatrics].
abstract: BACKGROUND
  Increasing life expectancy means growing numbers of elderly survive the critical age for cardiac and vascular diseases only to later experience cancer and dementia.
  
  
  OBJECTIVE
  Of the types of cancer affecting men, prostate cancer continues to be diagnosed early by prostate-specific antigen (PSA) screening. The clinical relevance and quality of life of those affected must be critically judged. Depending on life expectancy, active surveillance (AS) and watchful waiting (WW) will be increasingly used in geriatric patients. Risk stratification as guided by CGA facilitates the therapeutic decisions of urologists and spares metastatic castration-resistant prostate cancer patients from unnecessary and adverse overtreatment. By 2030, approximately 1.8 million people will have dementia.
  
  
  CONCLUSIONS
  Thus, in the future, the health care system will have to treat an aging population, which will require the creation of increasing numbers of geriatric hospital departments and cooperative models between geriatrics and other specialties. The future training of medical students and continuing medical education must also be further developed to include aspects on aging. Only in this manner will it be possible to effectively confront the challenges associated with demographic change in the specialty of geriatrics.
