Several disease that are frequently used for differential diagnoses include Binswangers disease, CADASIL, Nasu-Hakula disease, and chronic progressive multiple sclerosis. Treatment
There is currently no treatment or cure for CARASIL. Most frequently, a combination of supportive care and medications to prevent the occurrence of stroke are recommended. Counseling or other forms of emotional support may be beneficial to both patients and family members. Medications or therapies may be used to treat specific symptoms of the disease. Tizanidine and baclofen may be used to treat the spasticity of the limbs. A walker or cane may be used to assist individuals with gait disturbances. Anxiolytics may be prescribed for mood changes. Prognosis
The prognosis for individuals with CARASIL is progressive neurological decline over the course of 10–20 years after the onset of symptoms, ultimately ending in death. CARASIL is a degenerative disease, and most patients live only 10 years past symptom onset, although some may live for 20–30 more years. Epidemiology
Of the approximately 50 cases worldwide, the majority were found in Japan, with a few cases in China, Spain, Portugal, and Romania. CARASIL appears to affect males more often than females. A ratio of 7.5 males to 1 female was observed in Japan. Research
Research consists primarily of case studies reporting observed cases of CARASIL, one study suggests that a possible future treatment option may be inhibition of TGF-β signaling by an angiotensin I receptor agonist, due to the fact that an excess of TGF-β signaling is involved in causing CARASIL.
A large number of toxic plants may also cause symptoms.Some agents are more specific to a certain species. Transmissible gastroenteritis coronavirus (TGEV) occurs in pigs resulting in vomiting, diarrhea, and dehydration. It is believed to be introduced to pigs by wild birds and there is no specific treatment available. It is not transmissible to humans. See also
