Cluster Headaches: Types, Symptoms, Causes, and Treatment

What are Cluster Headaches?

One of the most unpleasant types of headaches is the cluster of headaches that occur in cyclic patterns of cluster periods. A cluster headache usually wakes you up in the middle of the night with tremendous pain in or around one of your eyes on one side of your head. Frequency of attacks known as cluster periods, usually followed by remission times, when the end of the headache, may extend from weeks to months. Over months and sometimes even years there is no headache during remission.

Luckily, headache in clusters is infrequent, and not endangering. Treatments can reduce and reduce the severity of headache cluster episodes. Medicines can also lower the number of headaches of the cluster. These types of headaches are the least prevalent and impact less than one in 1000 persons. More than women, men get them. Usually, you start before the age of 30. Cluster headaches may go totally for months or years (this is termed remission) but might return without a warning.

Why Are They Called Cluster Headaches?

The term headache is derived from the fact that the attacks are carried out in groups or clusters. A brief, appallingly intense headache attacks occur 1 to 8 times a day during the cluster cycle. It is frequently separated by remission periods or by free periods of Headache generally lasting months and years, which can continue for weeks or months.

People suffering from chronic headache clusters do not have remission times or remissions last less than one month at a time. Headache is often believed to be the most excruciating cluster of headaches: it was called “boring,” “blurring,” “hot poker” and “suicide headache.” It’s commonly referred to as “hot poker.”

Type of Cluster Headaches

There are two types of cluster headaches which are episodic and chronic.

Episodic cluster headaches occur consistently from one week to one year, followed by one month or longer without headache. In episodic cluster headaches, migraines occur for a week to a year and can continue until 12 months before the development of any other cluster.

Chronic clusters headache occurs routinely for more than a year and then is followed by headache-free time for less than one month.

Who Can Get Cluster Headache?

Usually, studies show that men get cluster headaches more compared to women. Although it can occur in all ages, most people who suffer cluster headaches are aged 20 to 50.

A lot of people are smokers and have cluster headache attacks. However, stopping smoking has no impact on cluster headaches. If you experience cluster headaches, alcohol can increase your chance of attack during that period. A parent or sibling with a headache cluster may increase your chance of getting it.

Cluster Headaches: Sign & Symptoms

A cluster of headache hits fast, usually without warning even if you have nausea and aura like migraine first. Common signs and headache symptoms include:

  • Excessive discomfort is often in, behind or about an eye, but which can extend to other areas of your face, head, and neck.
  • A one-sided pain
  • Restlessness
  • Too much tearing
  • Eye redness on the affected side
  • The runny nose on the affected side
  • Perspiration on the face or forehead of the affected side
  • Pale skin or flushing on the face.
  • Swelling on the affected side surrounding your eye
  • Eyelid droops on the affected side

Cluster Headaches: Causes

The specific cause of cluster headaches is uncertain, although cluster headaches show that biological clock (hypothalamus) disorders are important. Cluster headache isn’t usually related to triggers like meals, hormone changes, or stress as opposed to migraine and tension headache. However, once a cluster phase starts, alcohol drinking may split headaches quickly. For this reason, during a cluster period, many persons with headache prevent drinking. The use of medicines, such as nitroglycerin, a medicament used to treat cardiac diseases, is another probable causes.

Cluster Headaches: Triggers

Researchers do not know what is causing cluster headaches. The abrupt release of histamine or serotonin in the body is presumably connected. Cluster headaches can be triggered due to the following reasons:

  • Use of alcohol or tobacco.
  • Switch to a high altitude
  • Bright light
  • Training or workout
  • Heat by the weather or by the bath.
  • Nitrates-based foods like bacon or beef for lunch
  • Using cocaine

Cluster Headaches: Diagnosis

The headache cluster has a typical pain kind and attack pattern. Your description of your attacks, including your pain, location and severity, and related symptoms, will depend upon your diagnosis. How frequent and how long your headaches endure are crucial factors. Your physician will probably utilize certain ways to identify the type and causes of your headache.

Neurological test
Your doctor can do a neurological examination for physical signs of neurological illness. In patients with cluster headaches, the examination is frequently unremarkable. The doctor will employ several tests, including senses, reflexes, and nerves, to evaluate your brain function.

Imaging tests
You could recommend further examinations to eliminate other significant sources of headache, such as a tumour or aneurysm if you experience unique or difficult headaches or an abnormal neurological examination. Common imagery tests for the brain include.

MRI: This produces detailed images of the brain and blood vessels using a high magnetic field and radio waves.
CT Scan: Using several X-rays, you obtain comprehensive cross-sectional brain scans.

Cluster Headaches: Medication & Treatment

Cluster headaches have no treatment. The purpose of treatment is to reduce pain gravity, minimize the time of headache and prevent episodes. Because the pain of headache clusters occurs quickly and can decrease in a short period, headache cluster can be difficult to assess and treat, as quick medicines are needed. Some kinds of acute medicines can swiftly relieve pain. The following therapies have shown that they are the most effective in acute and preventive headache therapy.

Acute therapy

  • Oxygen: Inhaling pure oxygen briefly through a mask offers the most people who utilize it with remarkable alleviation. Within 15 minutes the impact of this safe and cheap technique can be felt. Oxygen is safe and has no adverse effects in general. The biggest disadvantage of oxygen is that you have to transport an oxygen cylinder and regulator so that treatment might be uncomfortable and sometimes inaccessible. There are small portable units, however, some still find that they are not practical.
  • Triptans: The regularly used injecting shape of sumatriptan (Imitrex) is also an efficient therapy for the acute headache of the cluster. During medical observation, the first injection may be given. Some people may benefit from the nasal spray using sumatriptan, but it isn’t as effective as an injection for most people and could take longer to work. If you have uncontrolled high blood pressure or cardiac illness, Sumatriptan is not suggested.

Zolmitriptan (Zomig) may also be used as another Triptan medicine for the relief of cluster headache in nasal spray form. This medicine can be an alternative if other types of quick-acting therapies cannot be tolerated. Oral medicines are relatively slow to act and typically do not help with intense cluster headaches.

  • Octreotide: Octreotide (Sandostatin), the brain hormone somatostatin synthetic injector, is a successful treatment for some people’s headache cluster. However, the overall impact is less effective and less rapid than triptans to reduce pain.
  • Local anaesthetics: The dormant impact of local anaesthetics like lidocaine may be useful in certain people against headache cluster pain when delivered by the nose (intranasal).
  • Dihydroergotamine: For some patients with cluster headache the injectable form of dihydroergotamine (D.H.E. 45) could be an effective pain reliever. This medicine is also available in inhaled form (intranasal), although for cluster headache this version has not proven beneficial.

Preventive Therapy
Preventive therapy begins with the beginning of the cluster episode to stop attacks.

The time and regularity of your episodes will depend on which medicine you use. You may tap the medications once the estimated time of the cluster event ends under your doctor’s advice.

  • Calcium channel blockers: Verapamil is the primary preventive agent for calcium channel blockers (Callan, Verlan and others). With other medicines, verapamil may be taken. Long-term use to control chronic headache cluster is occasionally necessary. Low blood pressure and constipation can include nausea, tiredness, ankle swelling.
  • Corticosteroid: Corticosteroid such as prednisone (Prednisone Intensol, Rayos), are quick-acting preventative medicines that can be useful for many clustered individuals with headaches. If a cluster of your headache has recently begun or if you tend to short cluster times and long remissions, your doctor may prescribe corticosteroids. While corticosteroids can be used for several days, major side effects such as diabetes, high blood pressure and cataracts render their long-term use unsuitable.
  • Lithium Carbonate: Cluster headache may be effectively averted by lithium carbonate (Lithobid), which is used to treat bipolar disturbance if other drugs have not prevented headaches of clusters. Tremor, increased thirst and diarrhoea are part of the side effects. The dose may be adjusted by your doctor to minimize adverse events. When you take this medicine, the development of more significant side effects, for example, kidney damage, are constantly monitored in your blood.
  • Nerve Block: If an anaesthetic or corticosteroid is injected into the area around your occipital nerve, which is located behind your skull, then chronic cluster headaches may be improved.An occipital nerve block may be helpful for temporary relief before preventive long-term medicines take place. It is usually taken alongside verapamil.

Anti-seizure medicines such as topiramate are another preventive drug used for cluster headaches (Topamax, Qudexy XR, others)

The operation can seldom be recommended for those who do not find relief with an aggressive medicine or cannot handle medicines or adverse effects with chronic cluster headaches.

Stimulation of sphenopalatine ganglion includes surgery to implant a neurostimulator operated by a remote, handheld device. Research has shown that pain relievers quickly and headaches are less frequent, but further studies are needed.

Several little investigations have revealed that stimulation of the occipital nerve may be advantageous on both sides. It requires an electrode to be implanted near one or two occipital nerves.

Some cluster surgical techniques seek to destroy the routes of the nerves that are supposed to be causing pain, usually the trigeminal nerve that serves the area behind and around the eye. The long-term benefits of destructive proceedings are nonetheless controversial. Also, it is rarely taken into consideration due to possible problems – include muscle weakening in the jaw or sensory loss in some areas of the face and head.

Potential Future Treatments
Several potential cluster headache therapies are being studied by researchers.

Occipital nerve stimulation: Your surgeon implants electrons in your head in this procedure and attaches them to a little pacemaker-like gadget (generator). The electrodes send impulses that can block or ease your signals of pain, to boost the occipital nerve area.

Several modest studies with occipital nerve stimulation have found that in certain persons with chronic cluster headaches the therapy reduced discomfort and frequency of headaches.

Deep brain stimulation: Deep brain stimulation is promising, though unproven treatment for headaches with clusters that are not responding to existing treatments. This method involves doctors implanting an electrode into the brain’s hypothalamus, which is related to the time of the cluster. The electrode is connected by your surgeon to a generator, which modifies the electric pulses of your brain and can help relieve your pain.

As an electrode deeply enters the brain, there are considerable hazards, like infection or haemorrhage. Hypothalamus deep brain stimulation can help persons with severe chronic cluster headaches who have not been treated satisfactorily with drugs.

Cluster Headaches: Prevention

It is crucial to find out what causes your headaches to avoid a cluster headache.

  • Don’t try to smoke and drink.
  • Keep a notebook describing what you did, eat or drink when your headache began.
  • Take your appointments with the journal. The diary information can help you prescribe a drug and a management strategy for preventing cluster headaches.

Cluster Headaches: Pressure Points

Pressure points can help relieve headaches.

1. Third Eye
The third eye pressure point can be found between the person’s eyes. Stimulate the third eye pressure with sustained pressure in a circular motion.

2. Drilling Bamboo
The pair of pressures are on each eyebrow inside, where the nose bridge joins the bone of the brow. Apply equal pressure on both sides with both index fingers. Alternatively, one location at a time stimulates and alternate between the sides.

3. Gates of consciousness
The empty chambers on either side of the spine, right below the base of the crane, are these pressure points. Activate these spots with the index and centre fingers of both hands using strong pressure. Alternatively, tie the thumbs into the hollow areas at the base of the skull and squeeze the fingers behind the head. Massaging consciousness gates can also help to reduce pain in the neck.

4. Shoulder well
Approximately midway between your shoulder joint and the base of your neck is the shoulder well pressure point. To apply a firm but mild pressure, use your index and middle fingers of the opposite hand. On the opposite side, remember to do the same.

The activation of the pressure point of the shoulder well can assist to alleviate stiffness or pressure in the shoulder and neck. This can make tension headaches easier.

5. Union Valley
A person will find a union valley placed between the thumb and index finger which is the loose skin. Pinch between the thumb and the index finger of the other hand.

Whether the thumb moves in small circles, hold the union valley pressure point or massage it. On the other hand, repeat this step.

Home Remedies for Cluster Headaches Relief

Although cluster headaches cannot be cured, lifestyle adjustments can contribute to reducing headaches.

Consistent sleep schedule
A regular sleep program can improve your circadian rhythm. Sleeping schedule consistent Research shows that following a consistent sleep plan can lead to fewer headaches in clusters.

Tobacco prevention
Smokers are more likely than non-smokers to experience headaches of their clusters. Although it may not cease smoking, it can assist to improve your body’s sleep patterns and nerve responses. It may be difficult to stop smoking, but it is achievable. Talk to a doctor about locating a cessation program for individual smoking.

Alcohol restriction
During cluster headaches, alcohol consumption might cause it. Consider restricting your intake of alcohol to prevent this.

Exercise every day
Daily cardiovascular practices can increase your brain circulation, lower stress, and promote sleep.

What Type of Doctor to Consult?

The type of doctor to ideally consult would be a neurologist. A neurologist treats brain, spinal cord, and nerve problems. You must have the correct doctor when you face serious disorders, such as stroke, Alzheimer’s disease, multiple sclerosis, or ALS. Your brain and memory function depend on excellent blood flow and good work for healthy nerves.

Cluster Headaches Vs Migraines

Cluster Headaches: One of the most painful types of headaches are cluster headaches that occur in cyclical patterns of cluster periods. A cluster headache usually awakens you with extreme pain on one side of your head in or around the middle of the night.

Migraine: Migraine is a disease of neurology that can produce several symptoms. It is often marked by severe, weak headaches. Symptoms may include nausea, vomiting, speech difficulties, numbness or tingling, and light and sound sensitivity. In families, migraines tend to occur and impact every age.

Cluster Headaches: FAQs

Q1: Are cluster headaches hereditary?
A rare, severe primary headache disorder is Cluster Headache (CH). Family and twin studies have suggested a genetic foundation; however, the way of transmission appears to differ, and the heritability levels are unclear.

Q2: Are cluster headaches common?
Cluster Headaches may be harder than a migraine, but it does not generally linger for as long. These are the least common headaches that affect less than one person in 1000. More than women do, men get them. You normally get them before you’re 30 years old.

Q3: Are cluster headaches a disability?
Symptoms can severely affect a person’s work capacity.

Q4: Are cluster headaches a neurological disorder?
Cluster headache is neurological conditions which are unilaterally severely affected by ipsilateral autonomous cranial symptoms. Cluster Headaches occur commonly more than once a day and usually occurs at bouts.

Q5: Can cluster headaches last for days?
Times of chronic clusters may persist for over one year or periods without pain may last less than a month. Throughout cluster: Headaches normally happen every day, often multiple times a day. A single assault may last between 15 and 3 hours.

Q6: Do cluster headaches cause nausea?
Severe pain in or about one eye or on one side of your head may include potential symptoms. On the affected side of the head, there may be tearing, nasal stuffiness and a runny nose. A cluster of headache occurs rapidly, typically without warning, even if you first have nausea and aura like a migraine.

Q7: Can cluster headaches be cured?
Cluster headaches have no treatment. Treatment aims at reducing pain severity, shortening the headache length and preventing episodes.

Q8: Can cluster headaches cause dizziness?
Yes, it can cause dizziness.

Q9: Can cluster headaches cause stroke?
Many individuals with cluster headaches have a migraine-like aura. Research indicates that the risk of stroke or transient ischemic attack can rise due to headaches accompanied by an aura (TIA). Symptoms of TIA are similar but endure relatively shortly to those of stroke.
