Fibromyalgia progression and association with other diseases and inheritance with management practices in humans

Fibromyalgia is a widespread pain disorder characterized by chronic, diffuse pain, about 1 to 5% around world. While more prevalent in women and adults, it can also manifest in children and adolescents. The specific pathophysiology of fibromyalgia remains unclear, but it is associated with neuronal over sensitization, reduced conditioned pain modulation, cognitive dysfunction, memory loss, and impaired information processing. It has now been categorized as a somatic symptom disorder. This study aimed to investigate fibromyalgia, focusing on its potential hereditary connections and management practices. A key pathophysiological aspect of fibromyalgia is central sensitization, marked by increased functional connectivity with pre-receptive brain areas, decreased connectivity with antinociceptive areas, and alterations in central nervous system neurotransmitters, also in size and shape of specific brain areas. Fibromyalgia is not directly inherited from parents to offspring, it does exhibit a tendency to cluster within families. The serotonin transporter gene, characterized by single nucleotide polymorphism with "S" (short) allele, is more prevalent in individuals with fibromyalgia and psychological distress. In conclusion, fibromyalgia is a widespread pain disorder with a substantial impact on the central nervous system, resulting in significant disability and an elevated risk of chronic diseases. Early diagnosis and intervention can minimize the impact of fibromyalgia. Physical therapy and non-drug therapies should be customized for each patient. The FDA has approved three drugs including pregabalin, duloxetine, and milnacipran for fibromyalgia treatment.
