Case Study and Discussion – Migraine and Headaches

A 20-year-old female presents with severe migraines. She has been treated for the last two years.

Pathophysiology of the Migraine Prodrome

Migraines are complex neurological disorders characterized by recurrent, severe headaches often accompanied by prodromal symptoms. The pathophysiology of the prodrome phase involves several mechanisms. During this phase, the brain has abnormal neuronal excitability and neurotransmitter imbalances. Cortical spreading depression (CSD), a wave of neuronal depolarization followed by suppression, is thought to play a pivotal role. CSD can lead to vasoconstriction and subsequent vasodilation, affecting cerebral blood flow (Lagman-Bartolome & Lay, 2019). These vascular changes and the release of neuropeptides, such as substance P and calcitonin gene-related peptide, contribute to pain and other prodromal symptoms, including mood changes and gastrointestinal disturbances.

Tension Headache vs. Cluster Headache

Tension Headache

Tension headaches are primarily associated with muscle tension and contraction, often due to stress or physical strain. This increases muscle tension in the head and neck region, resulting in a dull, band-like pain around the head. The pain is generally bilateral and steady and does not worsen with physical activity (Lagman-Bartolome & Lay, 2019). The underlying mechanisms are multifactorial, involving myofascial trigger points, sensitization of pain receptors, and stress-induced central sensitization.

Cluster Headache

In contrast, cluster headaches are characterized by severe, unilateral pain usually centered around the eye or temple. The pathophysiology of cluster headaches involves the activation of the trigeminal-autonomic reflex, leading to intense vascular changes, such as cranial vasodilation and inflammation of the ophthalmic division of the trigeminal nerve. This can result in excruciating pain, lacrimation, nasal congestion, and Horner’s syndrome (Lagman-Bartolome & Lay, 2019). The exact cause remains unclear, but hypothalamic dysfunction and altered regulation of the circadian rhythm have been implicated.

Pathophysiological Differences between Migraine and Tension Headache

Migraine headaches and tension headaches differ in their underlying pathophysiology. Migraines involve complex neuronal and vascular changes, including CSD, neuropeptide release, and vasomotor disturbances (Pavlović, 2020). These changes result in a throbbing, often unilateral headache associated with various prodromal and associated symptoms.

Tension headaches, on the other hand, primarily result from muscle tension and contraction, causing a steady, band-like headache typically affecting both sides of the head. While central sensitization plays a role in both conditions, the triggers and key mechanisms differ (Pavlović, 2020). Various factors, including genetics, often trigger migraines, while tension headaches are frequently induced by stress or physical strain.
