In several instances gastric crises have been mistaken for gastric ulcer. These gastric or gastralgic crises, as they are called by Charcot, by whom they have been best described,105 are most frequently associated with locomotor ataxia, but they may occur in connection with other diseases of the spinal cord (subacute myelitis, general spinal paralysis, and disseminated sclerosis), and an analogous affection has been described by Leyden106 as an independent disease under the name of periodical vomiting with severe gastralgic attacks. Gastric crises have been most carefully studied as a symptom in the prodromic stage of locomotor ataxia. The distinguishing features of these crises are the sudden onset and the atrocious severity of the gastric pain; the simultaneous occurrence of almost incessant vomiting; the habitual continuance of the paroxysms, almost without remission, for two or three days; the normal performance of the gastric functions in the intervals between the paroxysms, which may be months apart; the frequent association with other prodromic symptoms of locomotor ataxia, such as ocular disorders and fulgurating pains in the extremities; and the development after a time of ataxia. Leyden has observed during the attacks retraction of the abdomen without tension of the abdominal walls, obstinate constipation, scanty, dark-colored urine, even anuria for twenty-four hours, and increased frequency of the pulse (also noted by Charcot). Vulpian107 mentions a case in which there was vomiting of dark-colored blood, and in which naturally the diagnosis of gastric ulcer had been made. In the autopsies of Leyden and of Charcot no lesions of the stomach have been found.

The differential diagnosis of gastric ulcer from gastric cancer will be considered in the article on GASTRIC CANCER.
It has already been said that a part of the symptoms of gastric ulcer are due to an associated chronic catarrhal gastritis. Usually other symptoms are present which render possible the diagnosis of the ulcer. There is usually some apparent external or internal cause of chronic catarrhal gastritis, whereas the etiology of ulcer is obscure; in chronic gastritis gastralgic paroxysms and the peculiar fixed epigastric pain of gastric ulcer are usually absent; in chronic gastritis profuse hæmatemesis is a rare occurrence; and in gastritis the relief obtained by rest and proper regulation of the diet, although manifest, is usually less immediate and striking than in most cases of gastric ulcer.
The passage of gall-stones is usually sufficiently distinguished from gastric ulcer by the sudden onset and the sudden termination of the pain, by the situation of the pain to the right of the median line, by the complete relief in the intervals between the attacks, by the occurrence of jaundice, by the recognition sometimes of enlargement of the liver and of the gall-bladder, and by the detection of gall-stones in the feces.
There is not much danger of confounding abdominal aneurism and lead colic with gastric ulcer, and the points in their differential diagnosis are sufficiently apparent to require no description here. The diagnosis of duodenal ulcer from gastric ulcer will be discussed elsewhere. The different causes of gastric hemorrhage, a knowledge of which is essential to the diagnosis of gastric ulcer, will be considered in the article on HEMORRHAGE FROM THE STOMACH.
PROGNOSIS.—Although a decided majority of simple ulcers of the stomach cicatrize, nevertheless, in view of the frequently insidious course of the disease, the sudden perforations, the grave hemorrhages, the relapses, and the sequels of the disease, the prognosis must be pronounced serious.
The earlier the ulcer comes under treatment the better the prognosis. Old ulcers with thickened indurated margins containing altered blood-vessels naturally heal with greater difficulty than recently-formed ulcers.
