"Fibrositis" syndrome.

J R Rice

    The Medical Clinics of North America
    |March 1, 1986

    Summary
    This summary is machine-generated.

    Fibromyalgia (FS) pain may stem from central nervous system (CNS) dysfunction, specifically impaired pain modulation. Treatments targeting CNS pathways, like amitriptyline, show promise for managing this common pain syndrome.

    Area of Science:

    • Neuroscience
    • Pain Medicine
    • Psychiatry

    Background:

    • Fibromyalgia (FS) is a common pain syndrome with multifactorial origins, potentially involving personality, stress, and depression.
    • Disturbed sleep and neurochemical disturbances in CNS function may contribute to FS pathogenesis.
    • The exact physiological basis for FS pain and tender points remains incompletely understood.

    Purpose of the Study:

    • To explore the potential role of central nervous system (CNS) dysfunction in the manifestation of Fibromyalgia (FS).
    • To investigate the neurophysiological mechanisms underlying pain perception and tender points in FS.
    • To evaluate the therapeutic implications of a CNS-based understanding of FS.

    Main Methods:

    • Review of existing literature on FS pathophysiology and treatment responses.

    Related Experiment Videos

  • Analysis of the efficacy of peripheral versus central acting medications in FS.
  • Correlation of clinical findings (tender points, symptom distribution) with proposed CNS mechanisms.

    • Main Results:

    • Reduced midbrain/brainstem inhibition of nociceptive impulses offers a plausible explanation for FS pain and tender points.
    • Peripheral analgesics (NSAIDs) are often ineffective, while centrally acting agents (amitriptyline) show significant efficacy.
    • FS symptomatology suggests a physiological origin, likely involving CNS pain-modulation pathways, rather than conversion hysteria or peripheral soft tissue issues.

    Conclusions:

    • Impaired function of the CNS pain-modulation system is a likely contributor to Fibromyalgia (FS) symptoms.
    • This understanding provides a rational basis for therapeutic interventions targeting central pain pathways.
    • Physicians should diagnose and treat FS as a legitimate pain syndrome with a physiological basis.
