Study Notes
- Causes and manifestations of migraines, cluster headaches, and tension-type headaches.
Migraines
- Primary mechanism involves activation of the trigeminal nerve (cranial nerve V) and the trigeminovascular system
- Cortical Spreading Depression (CSD) triggers activation by self-propagating wave of neuronal and glial depolarization
- Key factors: vasodilation of dural blood vessels
- Other key factirs are release of neuropeptides, sterile inflammation of the meninges and sensitization of pain receptors
- External triggers include stress, specific foods, weather changes, and hormonal fluctuations
- Symptoms: throbbing/pulsating pain, typically unilateral but can be bilateral
- Often accompanied by nausea, vomiting, photophobia, and phonophobia
- Prodromal Phase: patients experience warning signs like yawning, fatigue, mood changes, or cravings before headache onset
- Aura affects about 20-30% of migraineurs and is characterized by visual disturbances (e.g., scintillating scotomas), sensory changes, or speech difficulties
- Postdrome: after the headache, individuals may feel drained or fatigued for hours to days
Cluster Headaches
- Underlying mechanism involves activation of the trigeminal autonomic reflex and pathways linking the hypothalamus to the trigeminal nerve
- The suprachiasmatic nucleus (SCN) in the hypothalamus regulates circadian rhythms
- Key processes include sympathetic underactivity and parasympathetic overactivity
- Also Trigeminal nerve activation is included in the key processes, which leads to facial pain, tearing, and nasal congestion
- Triggers include alcohol consumption, sleep disturbances, and irregular sleep-wake cycles
- Symptoms: excruciating, severe unilateral pain, often centered around or behind one eye.
- Autonomic Features: lacrimation (tearing), nasal congestion, rhinorrhea (runny nose), ptosis (drooping eyelid), and conjunctival injection (redness)
- Attacks frequently follow a daily or seasonal pattern
- Each attack typically lasts 15 minutes to 3 hours and can occur multiple times per day during a cluster period
Tension-Type Headaches
- Believed to originate from muscle tension and myofascial trigger points, typically in the head and neck
- Mechanisms involve increased pericranial muscle tension and tenderness
- Also mechanisms include Abnormal central pain processing and heightened sensitivity in pain pathways, especially within the trigeminal nerve system
- Emotional stress, poor posture, fatigue, and lack of sleep are common triggers
- Symptoms: dull, aching, or pressure-like pain, typically bilateral
- Pain Characteristics: described as a tight band around the head, involving the forehead, temples, and/or back of the neck
- Often associated with muscle tension in the neck, scalp, or shoulders
- Unlike migraines, there is typically no nausea, vomiting, or aura.
- Photophobia or phonophobia may be present, but not both simultaneously
