https://acrabstracts.org/abstract/increased-brain-functional-connectivity-to-the-insula-is-associated-with-nociplastic-pain-in-psoriatic-arthritis/
Flavia Sunzini, Kristian Stefanov, Salim Al-Wasity et. al.

Nov 14th, 2022 - Background/Purpose: Pain is a hallmark feature of psoriatic arthritis (PsA); however, its apparent multi-factorial nature makes it difficult for rheumatologists to assess and manage. Clinically, nociplastic processes appear to contribute to the PsA pain experience, as shown by frequent co-existing fibromyalgia (FM), a prototypical nociplastic pain disorder [1,2]. Yet there are no objective data...
