Cluster headache is defined as excruciating unilateral head pain which occurs
in brief episodes (15 minutes-2 hours). Clusters consist of headache that occur
daily for 3 weeks to 3 months, then remit. Typically there are bouts in early
July and early January. Thus cluster headaches are seasonal, and sometimes can be associated with other seasonal illnesses such as seasonal vertigo.
Cluster may awaken one from sleep (migraine
and tension usually won't). Some experience flushing, droopy eye, nasal stuffiness,
or eye tearing. Clusters are typically "side locked". They do not alternate sides. Men are affected 2 to 5 times more frequently than are women
(reverse of migraine). Unlike the situation for migraine, menopause does not
reduce the frequency and severity of headache in women. Perhaps related, attaining an advanced age does not reduce the frequency of cyclic vomiting either, which is treated somewhat similarly. There probably are several
mechanisms for same symptom complex - migraine variant, sphenopalatine neuralgia,
and perhaps a genetic syndrome involving circadian rhythms..
The reason for the peculiar periodicity of cluster headache has recently been
discussed (Pringsheim T, 2002). There are two genes -- the PER or period gene
located on the X chromosome and the timeless (TIM) gene. Both genes affect the
suprachiasmatic (STC) nucleus of the hypothalmus. These genes generate products
that control circadian rhythms. It seems reasonable to hypothesize that in cluster
headache there is a disturbance of this clock.
Paroxysmal hemicrania (PH) is ocasionally mistaken for cluster. Both disorders
are short-lived, unilateral, and accompanied by ipsilateral autonomic features.
The PH patients show a female predominance, a shorter attack duration (2-30
min), and often a greater attack frequency (5 or more/day). A prompt response
to indomethacin confirms the diagnosis (Lipton et al, 2003)
Acute Treatment of Cluster:
Cluster headaches are extremely painful and the author's present practice is to use multiple medications simultaneously when it recurs. The author's usual protocol is to combine a triptan (injection or nasal spray) with steroids and verapamil for prevention. The triptans are used for pain control, while waiting for the steroids and verapamil to take effect. McGeeney comments that injection, inhalation and nasal spray therapies are superior to oral treatment for acute treatment of cluster headache.
Below are acute treatments reported in the literature.
- Analgesics -- rarely effective, even narcotics.
- Intranasal Capsaicin. While effective for prevention, this is difficult to administer.
- Ergot and related medications including triptans.
- Ergot compounds and triptans work but may be addictive in this syndrome
due to rebound and requirements for frequent administration. Would start with
these anyway, as need a fast acting agent. The most effective agent is subcutaneous 6mg sumatriptan. According to McGeeny, SC sumatriptan and zolmatriptan nasal spray are the "premier abortive therapies" for cluster.
- Nasal DHE can be used and appears to be useful. Howver, there are better agents.
- Sumatriptan -- might differentiate migraine from neuralgia. Intranasal is the most effective method (Markey, 2003). Injectable is
the most reliable method. See also Hardebo, 1998. Oral triptans are unsuitable. Sumatriptan nasal spray is not nearly as good as the injectable method (McGeeney, 2019). Sumatriptan might be more suitable for use during the day, when an oxygen tank is not available.
- Zolmatriptan nasal spray (Markey, 2003). According to McGeeney, 6 mg of injectable sumatriptan works more quickly than zolmitriptan nasal spray.
- DHE-45 (Intranasal), or via an intravenous protocol. While this may work, there are better choices.
- Intranasal lidocaine. A 4% solution administered by drops (not spray) has been reported successful. (Markey 2003). This must be compounded as there is no commercial product.
- Oxygen (5-15 L flow x 10 min) also reportedly works in 50%.. According to McGeeney (2019), there is strong evidence for high-flow oxygen. He recommends 15 L/min via a nonbreather mask, to be administered for 15-20 minutes as soon as an attack begins. Oxygen concentators generally have a lower flow rate (1-5 L/min). A 15 L/min flow rate requires a supplier to provide a regulator that is higher than used for cardiopulmonary disease. Sometimes a "demand valve" such as used by divers is used. Welding oxygen is not inherently dangerous but is not as safe as medical oxygen (McGeeney, 2019).
- Steroids (Decadron 0.75 BID x 7 D). Other authors recommend prednisolone
(Bahra et al, 2002). Injections into the occipital area have also had some success, but this does not appear to be well documented.
- Surgical treatments
- Trigeminal nerve section -- can be used in intractable chronic cases (Jarrar
et al, 2003). We have never encountered this.
- Occipital nerve stimulation (Burns, 2009). Used in intractable cases.
- Vagus nerve stimulation (Nesbitt et al, 2015). Needs much more study.
- Xyrem (sodium oxybutate)
A new approach to acute cluster was reported by Khatami et al. Xyrem (Sodium oxybate), which induces extremely deep sleep, was reported to be effective in cluster(2011). It is our thought that as clusters normally occur in the middle of the night, someone on Xyrem might simply sleep through them. This seems to us to be potentially a better way of managing them than many of the medications above. Xyrem, however, has major barriers to obtaining a rapid prescription.
Butorphanol nasal spray is best avoided due to alarming rates of abuse, addiction and even death McGeeney (2019).
Prevention of cluster headache
- Lithium -- equivalent to verapamil in efficacy, but more side effects (Bussone et al, 1990). One trial reported using 300 mg 3 times/day, with 50% reduction after 2 weeks.
- Melatonin, in a dose of 10 mg every evening, was reported to stop attacks in 50% afte 5 days. (Schindler and Gottschalk, 2019) Some report using as much as 30 mg.
- Verapamil (Calan) prophylaxis often works (Schindler and Gottschalk, 2019) , but may be too slow in onset
(2 week) to be useful acutely. Verapamil works best in large doses -- 240 to 480/day. When used in this dose, heart monitoring is suggested. (Blau et al, 2004; Bussone et al, 1990; Cohen et al, 2007).
- The CGRP antagonists may be especially potent in Cluster.
There are a number of peculiar treatments such as Civamide (related to hot peppers), Warfarin (a blood thinner) that we advise against. The protocol here aims for an INR between 1.5-1.9. There have also been some limited reports of utility for antiepileptic migraine medications such as topiramate, gabapentin and sodium valproate. We do not think that invasive treatment such as use of simulators are reasonable in any but the persons who have failed all else.
