SUNCT syndrome
SUNCT syndrome
SUNCT syndrome (Short-lasting Unilateral Neuralgiform Headache with Conjunctival injection and Tearing) is a rare form of primary headaches, specifically a type of trigeminal autonomic cephalalgia. The syndrome is characterized by extremely short-lasting headaches, with a frequency that can range from 30 to 200 attacks per day. Pronunciation: /ˈsʌŋkt/
Etymology
The term SUNCT is an acronym derived from the main features of the syndrome: Short-lasting, Unilateral, Neuralgiform Headache with Conjunctival injection and Tearing.
Symptoms
The main symptoms of SUNCT syndrome are:
- Short-lasting headaches, typically lasting from 5 to 240 seconds.
- Unilateral pain, usually around the eye, temple, and sometimes the face.
- Neuralgiform pain, described as sharp, stabbing, or pulsating.
- Conjunctival injection (redness of the conjunctiva).
- Tearing from one eye.
Diagnosis
Diagnosis of SUNCT syndrome is based on the patient's symptoms and the exclusion of other conditions. Neuroimaging, such as MRI, may be used to rule out other causes of the symptoms.
Treatment
Treatment for SUNCT syndrome is challenging due to the frequency and short duration of the attacks. Medications such as lamotrigine and gabapentin have been used with some success.
