Judging by the total absence of American and English literature and the paucity of material on any forms of syphilis in the aged, neurosyphilis developing in old age has not interested many writers. A few American authors have noted its incidence or manifestations: Thom,1 Wile,2 and Sturgis.3 Lucke,4 in a study of 250 tabetics, reported two patients with earliest symptoms after 65 years. Tobias, Long and Cramer, Wilde and Thomas have reported cases developing in old age. Bumstead5 years ago stated: "Syphilis contracted in old age is frequently a very serious disease. Tertiary lesions are prone to appear early and visceral and nervous complications are frequent."
Several French authorities have emphasized the severity of syphilis developing in the aged: Fournier, Dulac, Renault, Ricord and others. Gailleton6 states that syphilis contracted after 60 years is nearly always rapidly fatal. Mendel7 in his book mentions
