| Annotation | The aim of this study was to describe the development of scientific literature on dementia in which the authors present a quantitative, bibliometric study of the literature based on Medline, covering 36 years (1974_2009). Two samples of references to dementia papers were retrieved, the main sample based on the MeSH term Dementia holding more than 88,500 references. The annual additions of references on dementia were compared with the addition to total Medline. Changes of `the Dementia to Medline ratio' (%) gave the best information on the development. Study results showed that publications on dementia increased 5.6 times faster than Medline. Most of this relative acceleration took place during 1980_1997, when the references on dementia increased from 0.17 to 0.78%. During the recent 12 years, the publications on dementia have been keeping pace with Medline and have stabilised around 0.8%. This study demonstrates a large increase of the literature on dementia, relative both to the development of all medical research and to all psychiatric research. The bibliometric approach may be questioned as quantitative methods treat articles as being of equal value, which is not true. If, for example, during a certain period, the research output is `inflated' by a great number of repetitive papers, the quantitative method will give an unfair picture of the development. However the relative method used in this study will give relevant results as, at each point of time, the proportion of `valuable research' ought to be about the same in the dementia group as in total Medline.
