Short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT)

Short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare headache disorder that mainly affects middle-aged individuals. The disorder is characterized by severe and recurrent headaches that last for seconds to minutes and occur on one side of the head.

The headaches are typically accompanied by symptoms such as redness of the eye on the affected side, tearing, and nasal congestion. The pain is often described as stabbing, burning, or electric shock-like in nature.

The exact cause of SUNCT is unknown, but it is believed to be related to abnormalities in the trigeminal nerve, which is responsible for sensation in the face and head. The disorder is often misdiagnosed as other headache disorders, such as cluster headaches or trigeminal neuralgia.

The diagnosis of SUNCT is based on the patient's symptoms and a neurological examination. Imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans may be performed to rule out other underlying conditions.

  1. Treatment
  2. Prevention

Treatment options for SUNCT include medications such as anti-seizure drugs, antidepressants, and nerve blocks. In some cases, surgery may be considered as a last resort. Prevention strategies include avoiding triggers that can worsen the headaches, such as alcohol and certain foods.

Overall, SUNCT is a rare and often misdiagnosed headache disorder that can significantly impact an individual's quality of life. Early diagnosis and treatment are important for managing the symptoms and improving the patient's overall well-being.
