Functional MRI activation in white matter during the Symbol Digit Modalities Test
BACKGROUND Recent evidence shows that functional magnetic resonance imaging (fMRI) can detect activation in white matter (WM). Such advances have important implications for understanding WM dysfunction. A key step in linking neuroimaging advances to the evaluation of clinical disorders is to examine whether WM activation can be detected at the individual level during clinical tests associated w...
متن کاملA symbol digit modalities test version suitable for functional MRI studies.
The Symbol Digit Modalities Test is an easy test used to assess cognitive impairment in a wide range of neurological diseases, like multiple sclerosis. We adapted the oral version of this cognitive task making it suitable for functional Magnetic Resonance Imaging studies. Symbol Digit Modalities Test performance was associated with increased brain activity in frontal and parietal areas involved...
متن کاملThe Symbol Digit Modalities Test - Oral version: Italian normative data.
In neuropsychological practice, the availability of effective and reliable tests is crucial. The Symbol Digit Modalities Test (SDMT) is widely used because it is easy to administer, reliable and also evaluates information processing speed. We set out to obtain normative data (currently unavailable for the Italian population) for the oral version of this test. Both age and education influenced p...
متن کاملEye and hand motor interactions with the Symbol Digit Modalities Test in early multiple sclerosis.
PURPOSE Eye and hand motor dysfunction may be present early in the disease course of relapsing-remitting multiple sclerosis (RRMS), and can affect the results on visual and written cognitive tests. We aimed to test for differences in saccadic initiation time (SI time) between RRMS patients and healthy controls, and whether SI time and hand motor speed interacted with the written version of the ...
متن کاملThe Symbol Digit Modalities Test is an effective cognitive screen in pediatric onset multiple sclerosis (MS).
OBJECTIVE To evaluate the Symbol Digit Modalities Test (SDMT) as a tool for identifying pediatric-onset MS patients at risk for cognitive impairment. BACKGROUND The SDMT is a brief measure of cognitive processing speed that is often used in adult MS patients. Approximately one-third of pediatric-onset MS patients have cognitive impairment and there is a need for an effective screening instrum...
