Central sensitivity syndromes: a new paradigm and group nosology for fibromyalgia and overlapping conditions, and the related issue of disease versus illness.

Abstract in brief

• Central sensitivity syndromes (CSS) are proposed as a new way to understand and categorize fibromyalgia and related overlapping conditions, emphasizing a biopsychosocial approach rather than purely psychosocial or organic explanations.
• Current terminologies like medically unexplained symptoms or somatization are considered outdated and not suitable for describing CSS, as they rely on a psychosocial framework that may hinder proper communication and patient care.
• Embracing CSS as a paradigm can enhance research, education, and treatment strategies, while the traditional disease versus illness distinction should be rejected to better reflect the complex nature of these conditions.]
