=TABOPARETIC NEUROSYPHILIS (“taboparesis”) is CLINICALLY a combination of the symptoms of TABES DORSALIS and those of GENERAL PARESIS. The COURSE of TABOPARESIS is likely to be from a characteristic tabes dorsalis (often of years’ standing) to a characteristic general paresis; the ultimate paretic picture is likely to retain various characteristics of tabes. The LABORATORY TESTS in the paretic phase are characteristic of ordinary (non-tabetic) general paresis. The PROGNOSIS, after the paretic phase has arrived, is apt to be that of general paresis.= =Case 16.= Joseph Sullivan, a waiter, 50 years of age, sought assistance at the Psychopathic Hospital voluntarily. His complaint of severe and lancinating pains in the legs, difficulty with his gait, and a feeling of constriction about the waist, was forthwith suggestive of tabes dorsalis. He was a rather poorly nourished, white-haired man, with a drooping of the left side of the face. The pupils reacted sluggishly to light, the right somewhat better than the left. A marked Romberg reaction could be demonstrated. Ataxia in walking was marked. There was some incoördination of the hands, considerable tremor, and writing was poorly performed. The ankle-jerks and knee-jerks were absent. On the whole, the diagnosis of TABES DORSALIS was clear enough. The most appealing situation was =mental=. Sullivan was exceedingly apprehensive about his condition on the ground that it was growing progressively worse; if it was to get worse, Sullivan feared he would commit suicide. From his own account, he had become irritable, quick-tempered, and often unreasonable. As usual in these cases, the question arose whether the depression was psychopathic or natural. =TABETIC SYMPTOMS AND SIGNS IN ORDER OF THEIR FREQUENCY= =ANALYSIS OF 250 CASES= PER CENT
