| dc.description | Thus far, three published studies have examined cognitive functioning in persons with Multiple Chemical Sensitivity (MCS). Cognitive impairments to substantiate the subjective complaints of individuals with MCS have not been found. No study, however, has yet examined the cognitive profile of MCS within the framework of Bell's Olfactory-Limbic Model. It predicts that cognitive weaknesses will be associated more with limbic (i.e., frontal and/or temporal lobe) regions of the brain than with non-limbic regions (i.e., posterior cortex). Matched MCS (N = 21), asthma (N = 21), and healthy control (N = 21) groups were tested on measures of cognitive functioning that have localizing value. Between-group comparisons showed that the MCS group performed as well as controls on all cognitive tasks. However, between-test comparisons showed that both the MCS and asthma groups performed significantly more poorly on tasks sensitive to frontal and temporal regions than to posterior regions. Subjective memory complaints were not related to memory task performance, but were related to anxiety and depression Additional research is needed before concluding that the Olfactory-Limbic Model adequately describes the cognitive strengths and weaknesses of MCS. Confounding factors such as medication use, chronic illness, and environmental reactivity need to be considered. There is no evidence on norm-based cognitive measures that brain damage, per se, has occurred in MCS patients. | en_US |
