Other potential causes of vomiting and diarrhea, white foam from the mouth include gastrointestinal parasites, bacterial infections including E. coli, Campylobacter, or Salmonella, protozoal infections such as coccidiosis or giardiasis, and gastrointestinal cancer. Treatment
The most important aspect of treatment of HGE is intravenous fluid therapy to replace lost fluid volume. The vomiting and diarrhea are treated symptomatically and will usually resolve after one to two days. Antibiotics targeting C. perfringens are also used but recent studies have shown no difference in outcome or survival rate between patients given antibiotics and those not when no signs of sepsis were present. In other words, if there are no signs of sepsis, antibiotics will not hasten a recovery or improve outcome. With prompt, aggressive treatment, the prognosis is good. There is less than 10 percent mortality with treatment, but 10 to 15 percent of cases will recur. See also

Treatment
No specific treatment for CADASIL is available. While most treatments for CADASIL patients symptoms – including migraine and stroke – are similar to those without CADASIL, these treatments are almost exclusively empiric, as data regarding their benefit to CADASIL patients are limited. Antiplatelet agents such as aspirin, dipyridamole, or clopidogrel might help prevent strokes; however, anticoagulation may be inadvisable given the propensity for microhemorrhages. Control of high blood pressure is particularly important in CADASIL patients. Short-term use of atorvastatin, a statin-type cholesterol-lowering medication, has not been shown to be beneficial in CADASIL patients cerebral hemodynamic parameters, although treatment of comorbidities such as high cholesterol is recommended. Stopping oral contraceptive pills may be recommended. Some authors advise against the use of triptan medications for migraine treatment, given their vasoconstrictive effects, although this sentiment is not universal. In this regard, the advent of the "Ditans" such as Lasmiditan, lacking vasoconstrictive effect, and the "Gepants" such as Ubrogepant and Rimegepant, are attractive alternatives, albeit not yet field-tested in this condition. As with other individuals, people with CADASIL should be encouraged to quit smoking.In one small study, around 1/3 of patients with CADASIL were found to have cerebral microhemorrhages (tiny areas of old blood) on MRI.L-arginine, a naturally occurring amino acid, has been proposed as a potential therapy for CADASIL, but as of 2017 there are no clinical studies supporting its use. Donepezil, normally used for Alzheimers Disease, was not shown not to improve executive functioning in CADASIL patients. Society and culture
John Ruskin has been suggested to have had CADASIL.
