Cluster Headache | Diagnosis & Treatment All you need to know

Introduction & Epidemiology

Headaches can manifest on their own but are also a very common symptom in neck pain patients as more than 60% of patients with a primary neck pain complaint report having concordant episodes of neck pain. Therefore it’s essential to find out what kind of headache the patient is suffering from.

To start off let’s differentiate between primary and secondary types of headaches. But what does this mean? Simply put, primary headaches are a “disease themselves” whereas, in secondary headaches, the headache is a symptom of another condition. So primary headaches would be migraines, tension-type headaches & cluster headaches. Secondary type headaches are headaches caused by tumors, hemorrhage, other trauma, TMJ dysfunction, substance overdose, or neck pain aka. The cervicogenic headache.

Now let’s take a closer look at cluster headaches, which are primary types of headaches.
Fischera et al. (2008) conducted a meta-analysis to assess the lifetime prevalence of cluster headache and found low numbers of 0,12% with a 1-year prevalence of 53 per 100,000 persons and the overall sex ratio was 4.3 (male to female). Cluster headache had a 1-year prevalence of 0,054%  among the working-aged population in a Swedish cohort (Manzoni et al. 2019)

Epidemiology

The following figure shows the prevalence of headaches on different continents around the world:

Clinical Picture & Examination

In order for a headache to qualify as a cluster headache it has to fulfill certain criteria (ICHD-III):

A. At least five attacks need to fulfill criteria B-D

B. An untreated episode lasts 15-180 minutes and shows severe or very severe unilateral orbital, supraorbital, and/or temporal pain

C. It matches either or both of the following:

1. at least one of the following signs and symptoms, ipsilateral to the headache:
   – conjunctival injection and/or lacrimation
   – nasal congestion and/or rhinorrhoea
   – eyelid edema– forehead and facial sweating
   – miosis and/or ptosis
2. a sense of restlessness or agitation. There are reports of patients pacing back and forth through the room, banging their heads due to the severe pain.

D. It occurs with a frequency between one every other day and 8 per day

Treatment

Treatment for cluster headache consists of medication, injections/suboccipital nerve blocks, or intracranial stimulation. We can distinguish between treatment for acute attack and preventative treatment as two facets of cluster headache management. Unfortunately, there are currently no options for physiotherapists to treat patients with cluster headaches.
Currently, only a case study has been published on the combination of endogenous neurostimulation and physiotherapy (Navarro-Fernández et al. 2019).

Acute

100% oxygen therapy is arguably the most well-known method of treating cluster headaches (Obermann et al. 2015). As compared to other types of headaches, cluster headaches are the only condition for which this strategy is a level A recommendation. A minimum of 66% of patients benefit from oxygen therapy. It takes less than ten minutes to take effect. Using oxygen has no risks or adverse effects, making it a great option for treatment. Sadly, oxygen therapy for those with cluster headaches—which can be challenging to obtain—is frequently not covered by insurance.

The only other level A-indicated therapy is triptans. Subcutaneous sumatriptan or nasal spray zolmitriptan delivery of these medications are both options (May et al. 2006). If subcutaneous injections are not tolerated, intranasal triptans might be given on the side opposite the headache. Intranasal sumatriptan (20 mg) and intranasal zolmitriptan (5 mg) are two options. As the onset period of oral medications, in whatever form, is frequently longer than the headache, they are not advised.

Alternative treatments include octreotide, ergotamine, and intranasal lidocaine (with a reported 33% response) (Matharu et al. 2004). Sadly, medication resistance develops in 10% to 20% of people with severe cluster headaches. Patients should be advised to stay away from triggers, particularly alcohol. Patients should be urged to cease smoking even though there is no evidence to suggest that doing so will reduce their likelihood of getting headaches.
