7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about neurocognitive disorder with Lewy bodies and death from neurocognitive disorder with Lewy bodies.
Meaning of neurocognitive disorder with Lewy bodies
(2)          For the purposes of this Statement of Principles, neurocognitive disorder with Lewy bodies means a central nervous system neurodegenerative disorder meeting the following clinical diagnostic criteria (derived from DSM-5):

             1. Evidence of major neurocognitive disorder or mild neurocognitive disorder.

              2. The disorder has an insidious onset and gradual progression.

              3. The disorder meets at least two of the following diagnostic features:

                (i)            fluctuating cognition with pronounced variations in attention and alertness;

                (ii)         recurrent visual hallucinations that are well formed and detailed;

                (iii)       spontaneous features of Parkinson's disease or secondary Parkinsonism at least one year after the clinical onset of cognitive symptoms; or

                (iv)        rapid eye movement (REM) sleep behaviour disorder.

            D.           The cognitive deficits in Criteria A, B and C are not primarily due to any of the following:

                (i)            delirium;

                (ii)         another mental disorder (for example, major depressive disorder, schizophrenia); or

                (iii)       cerebrovascular disease, another neurodegenerative disease (for example, Alzheimer disease, Parkinson's disease, Huntington's chorea), brain tumour, subdural haematoma, the effects of a substance, or systemic disorder (for example, hypothyroidism, vitamin B12 or folic acid deficiency, niacin deficiency, hypercalcaemia, neurosyphilis, human immunodeficiency virus infection).

Note:  DSM-5, major neurocognitive disorder and mild neurocognitive disorder are defined in the Schedule 1 – Dictionary.
(3)          While neurocognitive disorder with Lewy bodies attracts ICD‑10‑AM code G31.3 with F02.8, in applying this Statement of Principles the meaning of neurocognitive disorder with Lewy bodies is that given in subsection (2).
(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.
Death from neurocognitive disorder with Lewy bodies
(5)          For the purposes of this Statement of Principles, neurocognitive disorder with Lewy bodies, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's neurocognitive disorder with Lewy bodies.
Note: terminal event is defined in the Schedule 1 – Dictionary.
