The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about cerebrovascular accident (stroke) and death from cerebrovascular accident (stroke).
Meaning of cerebrovascular accident (stroke)
(2) For the purposes of this Statement of Principles, cerebrovascular accident (stroke):
(a) means a sudden loss of brain function due to brain ischaemia or intracerebral haemorrhage; and
(b) includes:
(i) transient ischaemic attack;
(ii) ischaemic stroke; and
(iii) intracerebral haemorrhage; and
(c) excludes:
(i) subclinical or asymptomatic cerebrovascular disease identified by neuroimaging ("silent stroke");
(ii) subarachnoid haemorrhage;
(iii) subdural haemorrhage; and
(iv) extradural haemorrhage.
Note: brain ischaemia and intracerebral haemorrhage are defined in the Schedule 1 - Dictionary.
(3) While cerebrovascular accident (stroke) attracts ICD‑10‑AM codes I61, I63, I64, G45.0, G45.1, G45.2, G45.8, G45.9 or G46, in applying this Statement of Principles the meaning of cerebrovascular accident (stroke) 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 cerebrovascular accident (stroke)
(5) For the purposes of this Statement of Principles, cerebrovascular accident (stroke), in relation to a person, includes death from a terminal event or condition that was contributed to by the person's cerebrovascular accident (stroke).
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that cerebrovascular accident (stroke) and death from cerebrovascular accident (stroke) 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.
