Brief Cognitive Assessment in MS

  • Cognitive impairment affects 40-70% of

individuals with MS (Chiaravallotti et al., 2008)

  • An expert panel recently convened by the

NMSS recommended (Kalb et al., 2018)

– Early baseline screening and annual re-screening

  • BICAMS (at least SDMT)

– Positive screen followed by comprehensive assessment

  • MACFIMS or other

Brief Cognitive Assessment in MS

  • Examples of abbreviated assessment

– BICAMS (Langdon et al., 2012) – Abbreviated MACFIMS (Gromisch et al., 2018)

  • 30 s SDMT (vs 90 s)
  • 1 trial BVMT-R (vs 3)
  • 2 trials CVLT-II (vs 5)
  • 1 letter COWAT (vs 3)
  • 1 card sort DKEFS (vs 2)
  • Improves efficiency, but cost effectiveness is

still problematic

RAVLT as alternative to CVLT-II

  • Some evidence for RAVLT as a potential

alternative to the CVLT-II (Beier et al., 2019)

– Both measures have 5 trials – RAVLT used in German BICAMS (Filser et al., 2018) – Have shown acceptable equivalence at greater levels of impairment for TBI (Stallings et al., 1995)

5/30/2019 5

Objective

  • To examine a modified version of the BICAMS –

using the RAVLT (instead of CVLT-II) – in assessing cognitive impairment in MS

– Examine correlations between the RAVLT and CVLT-II learning trial scores – Compare the rates of cognitive impairment observed on the RAVLT version versus the standard BICAMS – Assess the degree to which the RAVLT vs CVLT-II contribute to cognitive impairment on the standard BICAMS

Analyses

  • Pearson’s r correlation between RAVLT and

CVLT-II

  • Cohen’s kappa (κ) comparing rates of impairment

between standard BICAMS and modified version

  • Step-wise logistic regression

– Step 1: CVLT-II or RAVLT – Step 2: SDMT and BVMT-R – Outcome: BICAMS impairment (dichotomized) – Covariates: age, gender, education

Results

  • Impaired at 1.5 SD

– CVLT-II: 15% – RAVLT: 16% – BICAMS: 40% – Modified BICAMS: 41%

  • Impaired at 2.0 SD

– CVLT-II: 9% – RAVLT: 9% – BICAMS: 29% – Modified BICAMS: 28%

  • RAVLT vs CVLT-II:

r = .61, p < .001

Conclusions

  • Limitations

– Cross-sectional data – Highly-resourced sample

  • RAVLT correlates moderately with the CVLT-II
  • The RAVLT provides a potential alternative verbal learning

measure for brief cognitive screening in MS

  • Although the RAVLT can accurately predict BICAMS

impairment, it does not predict BICAMS impairment beyond that of the BVMT-R and SDMT
