Abstract

The age distribution of patients with dementia paralytica and tabes dorsalis as observed in this clinic has afforded the basis for this study. A large number of cases have occurred under the age of 30 years in the group of dementia paralytica patients of all ages. This observation was commented on by Felix Plaut,1 Josef Jadassohn,1 L. M. Pautrier 1 and Bruno Bloch 1 during their visits to this clinic. The age incidence was apparently much higher in their clinics in Europe, and the occurrence of dementia paralytica in acquired cases of syphilis in patients under 30 years of age was regarded by them as unusual.

It was thought important to compare this group of cases with a series of tabetic cases seen over exactly the same period and under the same conditions.

Accordingly, there are available for study over a period of eight years, from July 1925
