What does SUNA mean in PHYSIOLOGY

SUNA (Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms) is a rare, primary headache disorder characterized by brief, severe headaches accompanied by autonomic symptoms on one side of the head.

The main symptom of SUNA is sudden, intense pain on one side of the head, often described as a stabbing or throbbing sensation. The pain typically lasts for 15-120 minutes and is accompanied by autonomic symptoms such as tearing, redness, and sweating on the same side of the face.

The exact cause of SUNA is unknown, but it is believed to involve a dysfunction in the trigeminal nerve, which is responsible for sensation in the face. Some studies suggest that certain triggers, such as stress, fatigue, or changes in temperature, may contribute to SUNA attacks.

SUNA is diagnosed based on a thorough medical history and a physical examination. Your doctor will ask you about your symptoms, examine your head and neck, and rule out other potential causes of your headaches. SUNA is often diagnosed using the International Headache Society (IHS) criteria, which include the presence of characteristic symptoms and the absence of other underlying conditions.

Treatment for SUNA typically involves medications to relieve pain and prevent attacks. Acute treatments include pain relievers such as ibuprofen or acetaminophen. Preventive treatments may include anticonvulsants, triptans, or botulinum toxin injections. In some cases, nerve blocks or surgery may be considered.

SUNA is a chronic condition that cannot be cured, but its symptoms can be managed with appropriate treatment. With proper care, individuals with SUNA can lead full and active lives.
