What are Other Trigeminal Autonomic Cephalalgias (TAC)?
Trigeminal Autonomic Cephalalgias (TAC) are a group of painful headache disorders that are characterized by severe, unilateral head pain associated with autonomic symptoms such as tearing, redness, and swelling of the eye, nasal congestion or runny nose, and sweating on the affected side of the head. There are several types of TAC, including cluster headache, paroxysmal hemicrania, and SUNCT (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing).
Other Trigeminal Autonomic Cephalalgias (TAC) are a group of rare headache disorders that share some characteristics with the more common types of TAC. These disorders are often misdiagnosed or underdiagnosed due to their rarity and similarity to other headache disorders.
Types of Other Trigeminal Autonomic Cephalalgias (TAC)
- Hemicrania Continua: Hemicrania continua is a rare, chronic headache disorder that is characterized by continuous, unilateral head pain that is moderate to severe in intensity. The pain is usually accompanied by autonomic symptoms such as tearing, redness, and swelling of the eye, nasal congestion or runny nose, and sweating on the affected side of the head. The pain is usually responsive to the nonsteroidal anti-inflammatory drugs (NSAIDs) and indomethacin.
- Nummular Headache: Nummular headache is a rare, chronic headache disorder that is characterized by focal head pain that is usually in a circular or elliptical shape. The pain is usually unilateral but can also be bilateral and is often associated with autonomic symptoms such as tearing, redness, and swelling of the eye, nasal congestion or runny nose, and sweating on the affected side of the head. The pain is usually responsive to NSAIDs and indomethacin.
- Primary Stabbing Headache: Primary stabbing headache is a rare, benign headache disorder that is characterized by brief, stabbing pain in the head that lasts for seconds to minutes. The pain can occur anywhere in the head and is usually unilateral but can also be bilateral. The pain is not associated with autonomic symptoms and is usually responsive to simple analgesics.
Treatment Options for Other Trigeminal Autonomic Cephalalgias (TAC)
The treatment options for Other Trigeminal Autonomic Cephalalgias (TAC) depend on the specific type of headache disorder and the severity of the symptoms. In general, nonsteroidal anti-inflammatory drugs (NSA
