Brief Cognitive Assessment based
on Consensus Standards in the US
and Abroad
Dawn Langdon PhD
MS care providers needs
• Most interested in receiving consultation on
cognition (31.0%)
• Most interested in CME relating to cognition
(40.1%)
• Highest preference for live conference
Turner et al., JRRD 2006;43:25-34
MS patients’ information needs
• All those questions recommended information
about cognition in MS for all patients
• And on average to be given earlier than they
had received it
Heesen et al., Acta Neurol Scand 2006;114:268-272

Cognitive assessment for MS
• Requires specialist training
• Time-consuming
• Not routinely available outside specialist
centres
• Not comparable across countries
BICAMS
Brief International Cognitive Assessment for MS
• Identify a brief assessment tool for cognition in MS
– can be used by health care professionals who are not
cognitive specialists
– has international validation
• Specify an international validation protocol that can
be implemented in any country
• Agree guidelines on test-retest timing and clinically
significant change
