Abnormal functional neurocircuitry underpinning emotional processing in fibromyalgia.
Eur Arch Psychiatry Clin Neurosci

Article Synopsis
- Fibromyalgia is a chronic pain condition that often comes with emotional issues, and this study focused on how the brains of fibromyalgia patients respond to emotional stimuli compared to healthy controls.
- Researchers used fMRI to examine brain activation and functional connectivity in 30 female fibromyalgia patients and 31 healthy females while they completed tasks related to emotion processing.
- The results showed that fibromyalgia patients had increased activation in specific brain areas during these tasks and exhibited abnormal connectivity patterns, which may explain the common emotional disturbances associated with the condition.
Fibromyalgia is a chronic condition characterized by widespread pain, as well as numerous symptoms related to central sensitization such as: fatigue, cognitive disturbances, constipation/diarrhea and sensory hypersensitivity. Furthermore, depression and anxiety are prevalent comorbidities, accompanied by emotion processing and regulation difficulties. Although fibromyalgia physiopathology is still not fully understood, neuroimaging research methods have shown brain structural and functional alterations as well as neuroinflammation abnormalities.

Due to the lack of successful treatments and high relapse rate, more research is needed to understand this and other SUD. Here, we present the SUDMEX CONN dataset, a Mexican open dataset of 74 CUD patients (9 female) and matched 64 healthy controls (6 female) that includes demographic, cognitive, clinical, and magnetic resonance imaging (MRI) data.
