**What are Cluster Headaches ‍(CHs)?**



**Question:** What are Cluster ‌Headaches ⁣(CHs)?



**Answer:** Cluster⁣ headaches are a severe type of primary headache disorder that occurs in clusters, with ⁣periods of frequent headaches followed by periods of remission. These severe⁢ headaches⁢ typically occur on one side of the⁤ head,⁤ around the eye or temple, and are characterized by:



* Intense, piercing,‌ or burning pain



* Pain lasting for 15-180 minutes



*⁢ Occurring in clusters of up to 8 headaches per day



* ‍Frequency of clusters ranging from every other ⁢day⁤ to 8 clusters per year



**Symptoms:**



* Watery eye on the affected side

* Nasal⁤ congestion or runny nose

* Sensitivity to light and sound

* Nausea and vomiting



**Causes:**



The⁣ exact cause of CHs is unknown, but it’s believed to involve a dysfunction ‌in the hypothalamus, the part of the brain that regulates sleep and hormone ⁣release. Triggers such as alcohol, stress, ⁣or changes in ⁣sleep ‌patterns ⁤may contribute.



**Diagnosis:**



Diagnosis of CHs is ⁤based on symptoms and a comprehensive medical history. There​ are⁢ no specific ⁣tests to confirm CHs.



**Treatment:**



* **Acute‍ Treatment:** To relieve the pain of cluster attacks, oxygen therapy, triptans, ‌and dihydroergotamine (DHE) may be⁤ used.

* **Preventive Treatment:** To‍ reduce the frequency and duration of clusters, medications such as verapamil, topiramate, and lithium may be prescribed.



**Epidemiology:**



* ​More common in men than women

* Usually starts between the ‌ages of 20 and 50

* Affects approximately 0.1% of the population



**Other Types of Headache Disorders:**



* Tension-type headaches

* Migraines

* Sinus headaches



**Additional ⁣Information:**



*‌ CHs can significantly impact daily life and quality of life.

* Treatment options are available to‍ manage symptoms and reduce the burden of the disorder.

* Ongoing research ⁢is⁣ investigating the⁣ causes ⁣and​ potential new treatments for CHs.
