Editing Dementia praecox (section)

===Change in prognosis===
In the seventh, 1904, edition of {{lang|de|Psychiatrie}}, Kraepelin accepted the possibility that a small number of patients may recover from dementia praecox. [[Eugen Bleuler]] reported in 1908 that in many cases there was no inevitable progressive decline, there was temporary remission in some cases, and there were even cases of near recovery with the retention of some residual defect. In the eighth edition of Kraepelin's textbook, published in four volumes between 1909 and 1915, he described eleven forms of dementia, and dementia praecox was classed as one of the "endogenous dementias". Modifying his previous more gloomy prognosis in line with Bleuler's observations, Kraepelin reported that about 26% of his patients experienced partial remission of symptoms. Kraepelin died while working on the ninth edition of {{lang|de|Psychiatrie}} with Johannes Lange (1891–1938), who finished it and brought it to publication in 1927.<ref>{{harvnb|Noll|2007a|pp=[https://books.google.com/books?id=jzoJxps189IC&pg=PA126 126–7]}}</ref>
