Abstract:
Cognitive and behavioral impairments are core manifestations of fibromyalgia and may be more disabling than pain itself. Involvement of the central nervous system is ascertained by the fact that frontoparietal and limbic cortices are often functionally and structurally affected along the course of this disease. Even though neuroimaging has brought some experimental evidence to support such network disruption, there are currently no clinically effective biomarkers that detect and quantify cognitive and behavioral disturbances in fibromyalgia; thus, traditional scales and tests of neuropsychiatric assessment remain the most important diagnostic tools. This review addresses the most common cognitive and behavioral impairments in people with fibromyalgia, while explaining their pathophysiological basis and currently available therapeutic options.
