Of all of the regression patterns, the brand new memories design yielded the highest explanatory value appearing one to, in combination with sex, years, and you will EDSS, stress shows you 24% of the variance from inside the memories domain name (modified Roentgen dos =0

05). Generally, during the group height, SPMS clients scored down and you may PPMS people higher for the full ARCS get as opposed to those having RRMS. There had been zero mathematically tall differences when considering MS subtypes to the psychological state details (p>0.1). When you find yourself there can be no significant difference anywhere between male and female clients for these parameters, guys had a tendency to have all the way down mediocre recollections score compared with women (p=0.07).

Cognitive performance variables (ARCS scores) were converted to Z scores for bivariate correlation and regression analyses (see the Methods section). Bivariate analyses showed widespread negative correlations between clinical variables and the cognitive performance variables (p<0.05) (Table 2). The strongest negative correlation was observed between memory score and EDSS (r=?0.35, p=0.001). There was a general tendency for a lower cognitive performance, across all domains, to correlate with higher levels of stress, anxiety, and depression. The strongest individual mental health correlate of overall cognitive ability was anxiety (r=?0.27, p=0.004). Among the cognitive domains, anxiety also showed the strongest correlation with memory (r=?0.27, p=0.0005). The level of disability accumulation, as measured by EDSS, showed a weak correlation with both anxiety and depression indices (data not shown).

To assess the relative association of each of the mental health variables (depression, anxiety and stress) with cognitive ability in this MS patient cohort, we performed linear regression analyses factoring in these three main factors as well as relevant covariates. When analyzed separately, all three mood indices were significantly associated with overall cognitive performance, after accounting for significant clinical covariates (p<0.008). Interestingly, when we modeled all three mood indices together, anxiety was the only mental health variable that was significantly associated with cognitive function (Table 3). After conditioning on stress and depression, increased anxiety scores were significantly associated with reduced cognitive performance (?=?0.22, p<0.008). These results indicate that the association of stress and depression with cognitive outcome is no longer statistically significant in this model after accounting for the association with anxiety. Analyses of cognitive subdomains showed that the association of anxiety appeared to exist across the different cognitive domains but was strongest for memory (?=?0.22, p<0.008). 24, p<0.008).
