Reduced Hippocampus in Fibromyalgia Explains Cognitive Decline, Study Shows
shutterstock_85932820In a recent study entitled “Fibromyalgia patients have reduced hippocampal volume compared with healthy controls,” researchers report reduced volume in fibromyalgia patients’ hippocampus and suggest this phenotype may underline the symptoms of both memory and cognitive abnormalities. The study was published in the Journal of Pain Research.  Fibromyalgia (FM) is a disorder estimated to affect 5.8 million Americans and is characterized by widespread musculoskeletal pain, which often is accompanied by other symptoms, including fatigue, sleep, memory and mood problems. Notably, FM is currently thought of as a disease that also affects the central nervous system, with FM patients exhibiting cognitive abnormalities. Previous reports observed changes in size and function in brain regions, such as the cingulate, amygdala, thalamus, and the parahippocampal gyrus. Here, the authors determined if FM patients have differences in hippocampus volume due to its pivotal role in memory and spatial navigation. To accomplish this, the r
