Cluster headaches are considered one of the most painful types of headaches, with symptoms that include intense, piercing pain around one eye accompanied by redness and watering. These headaches can last anywhere from 15 minutes to three hours and typically occur in clusters that persist for weeks or months. It’s important for individuals who experience these symptoms to seek medical attention as soon as possible to receive an accurate diagnosis and effective treatment plan. Additionally, lifestyle changes such as avoiding known triggers (such as alcohol or tobacco use) may help manage symptoms and reduce the frequency of attacks.
Types of Cluster Headaches
- Episodic cluster headaches – They occur in cycles, with periods of remission in between the attacks that can last for weeks or months. During an active cycle, the person may experience several daily attacks for weeks to months.
- Chronic cluster headaches – They are characterised by daily attacks that continue for more than a year without any significant period of remission. These headaches are less common but can be more debilitating than episodic cluster headaches.
It is worth noting that while both types of cluster headaches have similar symptoms, such as severe pain around one eye, a runny nose and sweating in the face, chronic cluster headaches are longer-lasting and more severe compared to episodic cluster headaches.
Symptoms of cluster headaches
Cluster headaches are usually characterised by intense pain on one side of the head, around the eye or temple.
The pain is often described as a burning or piercing sensation lasting 15 minutes to 3 hours. Other symptoms of cluster headaches include redness and watering of the eye, nasal congestion, sweating, and restlessness.
Causes of Cluster Headaches
The exact cause of cluster headaches remains unknown; identifying and avoiding triggers can help reduce the frequency and severity of attacks. Some of these triggers are:
- Abnormal sleep pattern
- Alcohol consumption
People who suffer from sleep apnea or snore heavily are also at an increased risk of developing cluster headaches. There is also evidence to suggest that certain medications can trigger these types of headaches.
Diagnosis of Cluster Headaches
To diagnose cluster headaches, the below mentioned tests are utilised:
- Neurological tests – During a neurological examination for cluster headaches, the doctor will evaluate the patient’s reflexes, muscle strength, and coordination. They may also perform an eye exam to check for any abnormalities. Additionally, the doctor will ask about the patient’s medical history and symptoms to gather a complete picture of their condition.
- Other tests – They may also order imaging tests such as an MRI or CT scan to rule out other underlying conditions.
Treatment Options for Cluster Headaches
There are several treatment options for cluster headaches, including abortive treatments that stop an attack while it is happening and medications to prevent them.
- Medications – Medications such as triptans and oxygen therapy can help alleviate pain during a cluster period. The injection or nasal spray may contain a medicine such as sumatriptan, dihydroergotamine or zolmitriptan, which block the receptors in your brain that transmit pain signals.
- Lifestyle Changes – Lifestyle changes such as avoiding triggers such as alcohol and tobacco, getting regular sleep, and managing stress can also help prevent cluster headaches from occurring.
- NVNS – For more lasting relief, the healthcare provider can use a device called a noninvasive vagus nerve stimulator (nVNS) to the base of your skull, where it sends mild electrical signals to the area of the brain that signals pain.
