R. Näcke. Significance of inheritance in progressive paralysis. (Die Rolle der erblichen Belastung bei der Progressiven Paralyse der Irren). - Neurolog. Centralblatt. 1900. No. 16. 748 s

The author of the article is already known as a defender of the theory of the important meaning of inheritance during progress. paralysis. In more early works, he touches on this theory in detail, but now he gives further proof of it. By inheritance, he actually understands 6 factors: mental and nervous diseases, extraordinary (auf-fallend) character, paralysis (apoplexy), suicide and drunkenness. Out of 100 cases prog. paralysis, inheritance was undoubted or preceded by a huge likelihood in 43 paralytics, that is, in 43%. There are interesting cases where it was possible to see signs of inheritance in several family members at the same time.
