Dictionary have the meaning given when used in this instrument.\n\n7 Kind of injury, disease or death to which this Statement of Principles relates\n\n(1) This Statement of Principles is about multiple sclerosis and death from multiple sclerosis.\n\nMeaning of multiple sclerosis\n\n(2) For the purposes of this Statement of Principles, multiple sclerosis:\n\n(a) means a chronic relapsing-remitting or progressive disorder affecting the motor and sensory systems of the central nervous system and characterised by multiple focal regions of demyelination of neuronal axons, inflammation and gliosis occurring on multiple occasions; and\n\n(b) includes relapsing-remitting multiple sclerosis, primary progressive multiple sclerosis and secondary progressive multiple sclerosis; and\n\n(c) excludes:\n\n(i) clinically isolated syndrome;\n\n(ii) radiologically isolated syndrome;\n\n(iii) neuromyelitis optica;\n\n(iv) acute disseminated encephalomyelitis;\n\n(v) Marburg disease;\n\n(vi) Balo concentric sclerosis; and\n\n(vii) Schilder disease.\n\n(3) While multiple sclerosis attracts ICD‑10‑AM code G35, in applying this Statement of Principles the meaning of multiple sclerosis is that given in subsection (2).\n\n(4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.\n\nDeath from multiple sclerosis\n\n(5) For the purposes of this Statement of Principles, multiple sclerosis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's multiple sclerosis.\n\nNote: terminal event is defined in the Schedule 1 – Dictionary.\n\n8 Basis for determining the factors\n\nThe Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that multiple sclerosis and death from multiple sclerosis can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.\n\nNote: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.\n\n9 Factors that must exist\n\nAt least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting multiple sclerosis or death from multiple sclerosis with the circumstances of a person's relevant service:\n\n(1) having acute infectious mononucleosis before the clinical onset of multiple sclerosis;\n\n(2) smoking at least five pack-years of cigarettes, or the equivalent thereof in other tobacco products, before the clinical onset of multiple sclerosis, and where smoking has ceased, the clinical onset of multiple sclerosis has occurred within five years of cessation;\n\nNote: pack-years of cigarettes, or the equivalent thereof in other tobacco products is defined in the Schedule 1 -

One tailor-made cigarette approximates one gram of tobacco or one gram of cigar or pipe tobacco by weight. One pack-year of tailor-made cigarettes equates to 7.3 kilograms of smoking tobacco by weight. Tobacco products mean either cigarettes, pipe tobacco or cigars, smoked alone or in any combination.\n\n relevant service means:\n\n(a) operational service under the VEA;\n\n(b) peacekeeping service under the VEA;\n\n(c) hazardous service under the VEA;\n\n(d) British nuclear test defence service under the VEA;\n\n(e) warlike service under the MRCA; or\n\n(f) non-warlike service under the MRCA.\n\nNote: MRCA and VEA are also defined in the Schedule 1 - Dictionary.\n\n significant other means a person who has a close family bond or a close personal relationship and is important or influential in one's life.\n\n specified sunlight exposure levels means sunlight exposure four times a week on exposed arms and legs, or an equivalent body surface for the following amount of time:\n\n(a) 5 to 15 minutes, excluding winter exposure; or\n\n(b) 9 to 15 minutes between 0° and 23° latitude in winter; or\n\n(c) 20 to 30 minutes between 23° and 34° latitude in winter; or\n\n(d) 30 to 50 minutes between 34° and 60° latitude in winter.\n\n terminal event means the proximate or ultimate cause of death and includes the following:\n\n(a) pneumonia;\n\n(b) respiratory failure;\n\n(c) cardiac arrest;\n\n(d) circulatory failure; or\n\n(e) cessation of brain function.\n\n VEA means the Veterans' Entitlements Act 1986.\n\n \n","sortOrder":0}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":6,"scope_assessment":{"changed":false,"description":"The legislation maintains its original scope as a medical-determination instrument under Part XIA of the Veterans' Entitlements Act 1986.
