Sum maryObjective: Currently cognitive dysfunction is recognized as a significant cause of disability in multiple sclerosis (MS). The Montreal Cognitive Assessment (MOCA) test is a screening device used to evaluate executive functions, visuo-spatial abilities, language, attention, and concentration, abstract thinking, memory, and orientation domains. The aim of this study is to compare cognitive functions of MS patients with age-matched controls using MOCA test. Ma te ri al and Met hod: Thirty-nine subjects with a diagnosis of relapsing-remitting MS based on the 2010 revised McDonald criteria and 20 healthy volunteer controls participated in this study. Patients and controls were administered the Turkish version of MOCA test. Total and subgroup scores were compared. Re sults: Total MOCA score in MS patients and controls were 21.74±4.48 and 26.9±2.53, respectively. Total MOCA score of MS patients was significantly lower than controls (p=0.000). Significant deterioration was also found in language, attention, memory and executive functions domains. Disease duration and expanded disability status scale (EDSS) did not differ in patients with and without cognitive deficits. Dis cus si on: Patients with MS showed deterioration in language, attention, working and long term-memory and executive functions compared to controls. MOCA is a simple, stand-alone cognitive screening test with superior sensitivity. Our findings suggest that the MOCA test may be useful for screening cognitive impairment in MS patients early in the disease course.

Aortic dissection can be fatal in case of a missed diagnosis underdiagnosis, and early treatment is crucial to prevent mortality. Even though acute onset of chest or back pain is the most common presenting symptom, some patients might present with atypical findings such as acute stroke, mesenteric ischemia, renal failure or myocardial infarction. Here, we report two cases from the emergency room presenting with atypical findings of aortic dissection in which the diagnosis was made during etiologic work up for ischemic stroke. (Turkish Journal of Neurology 2014; 20:49-51) Key Words: Aortic dissection, ischemic stroke Aort diseksiyonu tanı konulmadığında ölümcül seyreden ve acil tedavi gerektiren bir hastalıktır. Aort diseksiyonunun en sık semptomları, ani göğüs veya sırt ağrısı olmakla birlikte bazı vakaların ağrısız olabileceği ve akut inme, mezenter iskemisi, renal yetmezlik, miyokard enfarktüsü gibi atipik bulgularla prezente olabileceği bilinmektedir. Biz, acil servise atipik semptomlarla başvuran, iskemik inme tanısı ile kliniğimizde takip edilmekte iken, etiyolojiye yönelik yapılan tetkikler sonucunda aort diseksiyonu tanısı alan iki olguyu bildiriyoruz.
