BACKGROUND Cognitive impairment in multiple sclerosis (MS) often involves attentional deficits. The Stroop colour word test, a measure of attention, lacks current normative data for an english-speaking North american MS population. Further some authors suggest the Stroop actually measures processing speed. OBJECTIVE To generate normative data for the Stroop colour word test that can be used f...

We analyzed the relationship between several measures of attention (e.g., sustained and divided attention) and measures of verbal memory (e.g., immediate and delayed memory) in children aged 8-17 years. The attentional measures were derived from several tests of attention: Trail-Making, Digit Cancellation, Digit-Symbol, and Digit-Span. The verbal memory measures were derived from the Rey Audito...

OBJECTIVE To investigate the effects of acute low-level exposure to carbon monoxide on higher cognitive functions in healthy humans. DESIGN An empirical study of the effects of low-level exposure to carbon monoxide on higher cognitive functions in young healthy volunteers and a matched nonexposed control group. SETTING A dormitory at the Hebrew University campus in Jerusalem, Israel. PART...

BACKGROUND There are a variety of techniques to handle missing data, such as removing observations with missing data from the analyses or estimating the missing values using various imputation algorithms. Dropping subjects from standard regression models and analyzing only completers, however, may bias results from the true value of reality. Likewise, 'last-observation-carried-forward' may not ...

The Flynn effect refers to the rise in IQ throughout the 20th century. This study examined whether the Flynn effect has also elevated performance on neuropsychological tests. A search of published norms revealed five tests with appropriate normative data available for comparison. These tests were the Trail-Making Test (TMT), Symbol Digit Modalities Test (SDMT), Boston Naming Test, Finger Tappin...

Cognitive abnormalities have been extensively studied in Multiple Sclerosis (MS). However, little is known about the cognitive involvement in patients with Clinically Isolated Syndrome (CIS). Objective This study aimed to investigate cognitive impairment in patients with CIS compared with healthy subjects. Methods 18 CIS patients and 18 controls were subjected to the Wechsler memory scale, ...

The capability of multilevel input ring-TCM coding scheme for generating high-rate codes with improved symbol Hamming and squared Euclidean distances is demonstrated. The existence of uniform codes and the decoder complexity are also considered.
