Information processing in primary fibromyalgia, major depression and healthy controls

J Rheumatol. 1995 Jan;22(1):137-42.


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 primary FM.

Conclusion: This finding would suggest that primary FM and depression are probably different conditions.
