7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about vascular neurocognitive disorder and death from vascular neurocognitive disorder.
Meaning of vascular neurocognitive disorder
(2)          For the purposes of this Statement of Principles, vascular neurocognitive disorder means a chronic vascular disorder of the brain, meeting the following clinical diagnostic criteria (derived from DSM-5-TR):

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

        B.     The clinical features are consistent with a vascular aetiology, as suggested by either of the following:
            (i)                 onset of the cognitive deficits is temporally related to one or more documented cerebrovascular events; or
            (ii)               evidence for decline is prominent in complex attention (including processing speed) and frontal-executive function.

        C.     There is evidence of the presence of cerebrovascular disease from history, physical examination, and/or neuroimaging considered sufficient to account for the neurocognitive deficits.

        D.    Vascular neurocognitive disorder includes:
            (i)                 acquired diffuse white matter disease (Binswanger disease);
            (ii)               multi-infarct dementia;
            (iii)            post-stroke dementia;
            (iv)             strategic infarct dementia;
            (v)               subcortical ischaemic vascular dementia;
            (vi)             dementia, major neurocognitive disorder or mild neurocognitive disorder due to vascular disease, including atherosclerosis;
            (vii)           vascular mild cognitive impairment without dementia.

        E.     The cognitive deficits in Criteria A, B, C and D are not primarily due to any of the following:
            (i)                 delirium;
            (ii)               another mental disorder (for example, major depressive disorder, schizophrenia); or
            (iii)            inherited diffuse white matter disease, mitochondrial disorders,  a 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 1: DSM-5-TR, major neurocognitive disorder and mild neurocognitive disorder are defined in the Schedule 1 – Dictionary.
Note 2: Vascular neurocognitive disorder is also known as vascular dementia.
(3)          While vascular neurocognitive disorder attracts ICD‑10‑AM code F01, in applying this Statement of Principles the meaning of vascular neurocognitive disorder 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 vascular neurocognitive disorder
(5)          For the purposes of this Statement of Principles, vascular neurocognitive disorder, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's vascular neurocognitive disorder.
Note: terminal event is defined in the Schedule 1 – Dictionary.
