OBJECTIVE. To assess the information processing capabilities in 25
patients with primary fibromyalgia (FM) by comparing them with
22 patients with major depression and 18 healthy controls.
METHODS. A broad range of tasks related to various
subcomponents of information processing were included.
RESULTS. Our results indicated that patients with primary FM
in general share with depressives a nonspecific deficit in
information processing capacity. However, our data showed that
cognitive dysfunction reflecting a presumed compromise of the
right hemisphere is present in major depression, but not in
CONCLUSION. This finding would suggest that
primary FM and depression are probably different conditions.
