COGNITIVE DYSFUNCTION IN FIBROMYALGIA: SLOW ACCESS TO THE MENTAL LEXICON.

- Abstract
Lexical access speed, the time needed for the brain to access the catalogue of words in long-term memory, is assumed to provide a foundation for a broad array of cognitive operations. It was hypothesized that defi cits in lexical speed are likely to play a central role in defi ciencies in cognitive performance of patients with fi bromyalgia, who as a group show defi cits in lexical speed. This was tested in a sample of 209 patients with fi bromyalgia and in 72 control patients with memory defi cits. Participants completed the Stroop word-naming measure of lexical access speed and 12 neurocognitive measures. Defi cit in lexical access speed occurred at approximately twice the frequency (48.3% vs 25.0%) in fi bromyalgia. The average delay in speed of lexical access was 171 msec. in fi bromyalgia and 163 msec. in controls. Those with defi cits in lexical access speed displayed defi ciencies on 10 of 12 cognitive measures in the fi bromyalgia group, and on 8 of 12 cognitive measures in the control group. The premise that lexical access speed is disproportionately present in fi bromyalgia and serves as a foundation for a wide array of cognitive operations is supported.
