(1)          This Statement of Principles is about cluster headache and death from cluster headache.
Meaning of cluster headache
(2)          For the purposes of this Statement of Principles, cluster headache:
(a)          means a headache condition in which there are multiple attacks of severe, unilateral headache in the orbital, supraorbital or temporal region, where each headache typically lasts from 15 to 180 minutes.  The headache is accompanied by a sense of restlessness or agitation, or at least one of the following autonomic symptoms occurring on the same side as the pain:
(i)            conjunctival injection or lacrimation;
(ii)         eyelid oedema;
(iii)       forehead and facial sweating;
(iv)        miosis or ptosis; or
(v)          nasal congestion or rhinorrhoea; and
(b)          includes episodic cluster headache and chronic cluster headache; and
(c)          excludes:
(i)            headache attributable to inflammatory disorders of the head and neck;
(ii)         headache attributable to structural abnormalities;
(iii)       headache attributable to systemic disease;
(iv)        hemicrania continua;
(v)          migraine;
(vi)        paroxysmal hemicrania;
(vii)     short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT);
(viii)   short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA);
(ix)        tension-type headache; and
(x)          trigeminal neuralgia.
            Note:   Headache attacks in cluster headache typically occur at a frequency between one every other day and eight per day.  In episodic cluster headache disorder only, cluster headache attacks occur in bouts separated by asymptomatic periods which are free from cluster headache attacks.

Death from cluster headache
(5)          For the purposes of this Statement of Principles, cluster headache, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's cluster headache.
