7               Kind of injury, disease or death to which this Statement of Principles relates
(1)          This Statement of Principles is about schizophrenia and death from schizophrenia.
Meaning of schizophrenia
(2)          For the purposes of this Statement of Principles, schizophrenia means a disorder of mental health meeting the following diagnostic criteria (derived from DSM-5):
A. Two (or more) of the following, each present for a significant portion of time during a one-month period (or less if successfully treated), at least one being (i), (ii) or (iii):

                 (i)             delusions;
(ii)          hallucinations;
(iii)        disorganised speech (for example, frequent derailment or incoherence);
(iv)         grossly disorganised or catatonic behaviour; or
(v)           negative symptoms (that is, diminished emotional expression or avolition).
B. For a significant portion of the time since the onset of the disturbance, level of functioning in one or more major areas of life, such as work, interpersonal relations, or self-care, is markedly below the level achieved prior to the onset (or when the onset is in childhood or adolescence, there is failure to achieve expected level of interpersonal, academic or occupational functioning).
C. Continuous signs of the disturbance persist for at least six months.  This six-month period must include at least one month of symptoms (or less if successfully treated) that meet Criterion A and may include periods of prodromal or residual symptoms.  During these prodromal or residual periods, the signs of the disturbance may be manifested by only negative symptoms or by two or more symptoms listed in Criterion A present in an attenuated form (for example, odd beliefs, unusual perceptual experiences).
D. Schizoaffective disorder and depressive or bipolar disorder with psychotic features have been ruled out because either:

                 (i)            no major depressive or manic episodes have occurred concurrently with the active-phase symptoms; or
                 (ii)         if mood episodes have occurred during active-phase symptoms, they have been present for a minority of the total duration of the active and residual periods of the illness.

E. The disturbance is not attributable to the physiological effects of a substance (for example, a drug of abuse, a medication) or another medical condition.
F. If there is a history of autism spectrum disorder or a communication disorder of childhood onset, the additional diagnosis of schizophrenia is made only if prominent delusions or hallucinations, in addition to the other required symptoms of schizophrenia, are also present for at least one month (or less if successfully treated).
Note: DSM-5 is defined in the Schedule 1 – Dictionary.
(3)          While schizophrenia attracts ICD‑10‑AM code F20.0-F20.3, F20.5 or F20.9, in applying this Statement of Principles the meaning of schizophrenia is that given in subsection (2).
(4)          For subsection (3), a reference to an ICD‑10‑AM code is a reference to the code
