It is related to a deficiency of orexin due to selective loss of orexin-secreting neurons in the hypothalamus, with little or no detectable orexin in the cerebrospinal fluid.\n\nNote 2: Narcolepsy type 2 is characterised by sleepiness that may occur with hypnagogic hallucinations and sleep paralysis, but cataplexy is not present. Levels of cerebrospinal fluid orexin are usually normal.\n\nNote 3: The diagnosis of narcolepsy is established by appropriate clinical testing, including sleep studies, the multiple sleep latency test (MSLT) and measurement of orexin levels in the cerebrospinal fluid.\n\nNote 4: Examples of other conditions that can cause daytime sleepiness include circadian rhythm sleep-wake disorders (for example, rotating shift work), insufficient sleep, and the effect of medication or substances or their withdrawal.\n\nNote 5: cataplexy, hypnagogic hallucinations and sleep paralysis are defined in the Schedule 1 - Dictionary.\n\n(3)          While narcolepsy attracts ICD‑10‑AM code G47.4, in applying this Statement of Principles the meaning of narcolepsy 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 narcolepsy\n\n(5)          For the purposes of this Statement of Principles, narcolepsy, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's narcolepsy.\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 narcolepsy and death from narcolepsy 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 narcolepsy or death from narcolepsy with the circumstances of a person's relevant service:\n\n(1)          having concussion or moderate to severe traumatic brain injury within the 2 years before the clinical onset of narcolepsy, and in the case of sustained unconsciousness following injury to the head, the clinical onset of narcolepsy occurred within 2 years of regaining consciousness;\n\n(2)          having a neurosurgical procedure involving the hypothalamus, midbrain or brainstem, within the 2 years before the clinical onset of narcolepsy;\n\n(3)          undergoing a course of therapeutic radiation for cancer, where the brain was in the field of radiation, within the 3 years before the clinical onset of narcolepsy;\n\n(4)          having a neurological disease, neurodegenerative disease or a paraneoplastic neurological syndrome, where the disease or syndrome involves the hypothalamus, midbrain or brainstem, within the 2 years before the clinical onset of narcolepsy;\n\nNote: Examples of neurological diseases, neurodegenerative diseases or paraneoplastic neurological syndromes that can involve the hypothalamus, midbrain or brainstem include:\n\n(i)              cerebrovascular accident;\n\n(ii)            disseminated encephalomyelitis;\n\n(iii)          hypoxic cerebral insult;\n\n(iv)           multiple sclerosis;\n\n(v)            neuromyelitis optica spectrum disorder; and\n\n(vi)           Parkinson's disease.\n\n(5)          having:\n\n(a)          a benign or malignant neoplasm; or\n\n(b)          a non-malignant space occupying lesion;\n\ninvolving the hypothalamus, midbrain or brainstem within the 2 years before the clinical onset of narcolepsy;\n\nNote 1: Examples of neoplasms that can involve the hypothalamus, midbrain or brainstem include lymphoma, glioma and craniopharyngioma.\n\nNote 2: Examples of non-malignant space occupying lesions that can involve the hypothalamus, midbrain or brainstem include neurosarcoidosis and vascular malformations.\n\n(6)          receiving the adjuvanted influenza H1N1 vaccine PandemrixTM within the 2 years before the clinical onset of narcolepsy;\n\n(7)          having infection with H1N1 influenza virus within the 2 years before the clinical onset of narcolepsy;\n\n(8)          having infection of the pharynx with Streptococcus pyogenes within the 3 years before the clinical onset of narcolepsy;\n\n(9)          having concussion or moderate to severe traumatic brain injury within the 2 years before the clinical worsening of narcolepsy, and in the case of sustained unconsciousness following injury to the head, the clinical worsening of narcolepsy occurred within 2 years of regaining consciousness;\n\n(10)      having a neurosurgical procedure involving the hypothalamus, midbrain or brainstem, within the 2 years before the clinical worsening of narcolepsy;\n\n(11)      undergoing a course of therapeutic radiation for cancer, where the brain was in the field of radiation, within the 3 years before the clinical worsening of narcolepsy;\n\n(12)      having a neurological disease, neurodegenerative disease or a paraneoplastic neurological syndrome, where the disease or syndrome involves the hypothalamus, midbrain or brainstem, within the 2 years before the clinical worsening of narcolepsy;\n\nNote: Examples of neurological diseases, neurodegenerative diseases or paraneoplastic neurological syndromes that can involve the hypothalamus, midbrain or brainstem include:\n\n(i)              cerebrovascular accident;\n\n(ii)            disseminated encephalomyelitis;\n\n(iii)          hypoxic cerebral insult;\n\n(iv)           multiple sclerosis;\n\n(v)            neuromyelitis optica spectrum disorder; and\n\n(vi)           Parkinson's disease.\n\n(13)      having:\n\n(a)          a benign or malignant neoplasm; or\n\n(b)          a non-malignant space occupying lesion;\n\ninvolving the hypothalamus, midbrain or brainstem within the 2 years before the clinical worsening of narcolepsy;\n\nNote 1: Examples of neoplasms that can involve the hypothalamus, midbrain or brainstem include lymphoma, glioma and craniopharyngioma.\n\nNote 2: Examples of non-malignant space occupying lesions that can involve the hypothalamus, midbrain or brainstem include neurosarcoidosis and vascular malformations.\n\n(14)      receiving the adjuvanted influenza H1N1 vaccine PandemrixTM within the 2 years before the clinical worsening of narcolepsy;\n\n(15)      having infection with H1N1 influenza virus within the 2 years before the clinical worsening of narcolepsy;\n\n(16)      having infection of the pharynx with Streptococcus pyogenes within the 3 years before the clinical worsening of narcolepsy;\n\n(17)      inability to obtain appropriate clinical management for narcolepsy.\n\n10           Relationship to service\n\n(1)          The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.\n\n(2)          The factors set out in subsections 9(9) to 9(17) apply only to material contribution to, or aggravation of, narcolepsy where the person's narcolepsy was suffered or contracted before or during (but did not arise out of) the person's relevant service.\n\n11           Factors referring to an injury or disease covered by another Statement of Principles\n\nIn this Statement of Principles:\n\n(1)          if a factor referred to in section 9 applies in relation to a person; and\n\n(2)          that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA;\n\nthen the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.\n\n \n\n \n\nSchedule 1 - Dictionary  \n\nNote:               See Section 6\n\n1               Definitions\n\nIn this instrument:\n\n                                cataplexy means a transient attack of extreme generalised weakness, often precipitated by an emotional response, such as surprise, fear or anger.\n\n                               hypnagogic hallucinations means vivid, often frightening visual, tactile or auditory hallucinations that occur as the person is falling asleep.\n\n                               MRCA means the Military Rehabilitation and Compensation Act 2004.\n\n                               narcolepsy—see subsection 7(2).\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;
