Decentralization supersensitivity in headache and central panalgesia
Research and Clinical Studies in Headache
|January 1, 1978
Summary
Central panalgesia involves systemic pain linked to increased monoamine receptor sensitivity in peripheral nerves. This supersensitivity may stem from neurotransmitter deficiencies, impacting pain perception and potentially causing conditions like migraines.
Area of Science:
- Neuroscience
- Pain Management
- Pharmacology
Background:
- Central panalgesia encompasses systemic pain disorders like hysteria, fibrositis, and masked depression.
- Peripheral neuromuscular junction sensitivity is implicated in these conditions.
Purpose of the Study:
- To investigate the role of monoamine receptor sensitivity in central panalgesia.
- To explore the mechanisms underlying neurotransmitter imbalances and pain perception.
Main Methods:
- Utilized pupillometry to assess iris neuromuscular junctions.
- Employed computerized venotest to evaluate vein neuromuscular junctions.
- Measured monoamine receptor sensitivity, including 5-HT, dopamine, noradrenaline, and tyramine.
Main Results:
- Demonstrated significantly increased monoamine receptor sensitivity, particularly 5-HT (up to 1,000-fold) in veins.
- Observed decentralization supersensitivity in veins, extending to various monoamines.
- Found evidence supporting a neurotransmitter deficiency theory leading to central and peripheral supersensitivity.
Conclusions:
- Increased central and peripheral monoamine supersensitivity is a key feature of central panalgesia.
- This supersensitivity mechanism is also relevant to idiopathic headaches, including migraines.
- Findings suggest potential therapeutic targets for pain management by addressing neurotransmitter imbalances.
