    Study Notes

    Trigeminal Autonomic Cephalgias (TAC)

    • Group of headaches with short-lasting, severe, unilateral pain and autonomic nervous system symptoms
    • Includes cluster headaches, paroxysmal hemicrania, SUNCT, and hemicrania continua

    Cluster Headaches

    • Primarily affects young males
    • Excruciating pain, often described as stabbing or boring
    • Located unilaterally around the eye
    • Associated with ipsilateral autonomic symptoms like conjunctival congestion, lacrimation, nasal congestion, and forehead/facial sweating
    • Attacks last 15 minutes to 3 hours, typically 30 minutes
    • Occur 1 to 8 times a day, lasting for 8 to 10 weeks followed by a symptom-free period
    • May be triggered by alcohol, but not skin stimulation
    • 20% of cases are chronic

    Other Headache Types

    • Ophthalmoplegic migraine: Transient third nerve palsy, often affecting pupil
    • Retinal migraine: Unilateral visual impairment
    • Basilar type migraine: Occipital involvement, associated with ataxia, tinnitus, vertigo
    • Familial hemiplegic migraine: Inherited condition related to calcium channel dysfunction

    Treatment

    Acute Headache

    • Very Severe pain: Sumatriptan (SC) or Zolmitriptan (intranasal)
    • Note: Triptans are contraindicated in cardiovascular or cerebrovascular disease and their efficacy depends on how quickly they reach peak concentration in the body. They are not effective for migraines with aura. Ergotamine is associated with a lower risk of recurrence.
