  "abstract": "The invention is a method for reducing headache pain and symptoms associated with the onset or occurrence of headache in mammals. The method is performed by delivering an invertebrate presynaptic neurotoxin to a mammal extramuscularly (preferably at a localized, site of pain), or at a site in one or more muscles (preferably muscles of the face, cranium and neck). The presynaptic neurotoxins administered according to the invention are those neurotoxins that are known to produce a reversible, flaccid paralysis of muscle tissue in mammals. The preferred neurotoxin for use in the method of the invention is Botulinum toxin, particularly Botulinum toxin A.",
  "claims": [
    "1. A method for reduction of pain associated with a migraine headache in a mammal comprising administering a therapeutically effective amount of an invertebrate presynaptic neurotoxin in a pharmaceutically safe form to the mammal.",
    "2. The method according to claim 1 wherein the neurotoxin is delivered to the face, cranium and neck.",
    "3. The method according to claim 2 wherein the presynaptic neurotoxin is delivered to one or more of the frontalis, corrugator, procerus and bilateral temporal muscles.",
    "4. The method according to claim 2 wherein the presynaptic neurotoxin is also delivered to the mammal's back.",
    "5. The method according to claim 1 wherein the presynaptic neurotoxin is administered by electromyographical injection into the muscle.",
    "6. The method according to claim 1 wherein the presynaptic neurotoxin is administered by injection in the area of the neuromuscular junction.",
    "7. The method according to claim 1 wherein the presynaptic neurotoxin is a Botulinum toxin.",
    "8. The method according to claim 7 wherein the Botulinum toxin is Botulinim toxin A.",
    "9. The method according to claim 1 wherein the presynaptic neurotoxin is a biologically active fragment of a proteinaceous toxin.",
    "10. The method according to claim 9 wherein the biologically active fragment is the lbc fragment of the Tetanus toxin.",
    "11. A method for reduction of symptoms associated with the onset or presence of a migraine headache in a mammal comprising administering a therapeutically effective amount of an invertebrate presynaptic neurotoxin in a pharmaceutically safe form to the mammal.",
    "12. A method for reduction of pain associated with a migraine headache in a mammal comprising administering a therapeutically effective amount of an invertebrate presynaptic neurotoxin in a pharmaceutically safe form to the mammal by delivery of the presynaptic neurotoxin to an extramuscular site of the face, cranium or neck.",
    "13. The method according to claim 12 wherein the neurotoxin is delivered to one or more target sites of the migraine headache pain experienced by the mammal.",
    "14. The method according to claim 13 wherein the presynaptic neurotoxin is delivered to one or more of the frontal, temporal and suboccipital areas of the face.",
    "15. The method according to claim 12 wherein the presynaptic neurotoxin is administered by perivascular injection.",
    "16. The method according to claim 12 wherein the presynaptic neurotoxin is administered by subcutaneous injection.",
    "17. The method according to claim 12 wherein the presynaptic neurotoxin is a Botulinum toxin.",
    "18. The method according to claim 17 wherein the Botulinum toxin is Botulinum toxin A.",
    "19. The method according to claim 12 wherein the presynaptic neurotoxin is a biologically active fragment of a proteinaceous toxin.",
    "20. The method according to claim 19 wherein the biologically active fragment is the Ibc fragment of the Tetanus toxin.",
    "21. A method for reduction of symptoms associated with the onset or presence of a migraine headache in a mammal comprising administering a therapeutically effective amount of an invertebrate presynaptic neurotoxin in a pharmaceutically safe form to the mammal by delivery of the presynaptic neurotoxin to an extramuscular site in the face, cranium or neck."
