Signs and Symptoms of Vascular Headache
Vascular headaches, primarily represented by migraine, present with recurrent moderate-to-severe headache attacks lasting 4-72 hours, characterized by unilateral (though bilateral in ~40% of cases) pulsating pain that worsens with physical activity, accompanied by nausea/vomiting and photophobia/phonophobia 1.
Core Clinical Features
Pain Characteristics
- Intensity: Moderate to severe pain that interferes with daily activities
- Quality: Pulsating or throbbing in nature 1, 2
- Location: Unilateral in the majority, but bilateral presentation occurs in approximately 40% of patients 1
- Duration: Individual attacks last 4-72 hours when untreated 1
- Aggravation: Worsens with routine physical activity such as walking or climbing stairs 1
Associated Symptoms
Autonomic and Systemic Features:
- Nausea and/or vomiting 1
- Photophobia (light sensitivity) 1, 2
- Phonophobia (sound sensitivity) 1
- Local autonomic signs including tearing and rhinorrhea 2
Temporal Phases
Prodromal Symptoms (occurring before headache onset):
- Depressed mood
- Excessive yawning
- Fatigue
- Food cravings 1
Postdromal Symptoms (lasting up to 48 hours after headache resolution):
- Tiredness
- Concentration difficulties
- Neck stiffness 1
Aura Symptoms (Present in ~33% of Migraine Cases)
Visual aura (>90% of those with aura) 1:
- Fortification spectra (classic zigzag patterns)
- Transient focal neurological symptoms
- Gradual spread over ≥5 minutes (key differentiator from stroke/TIA) 1
Sensory aura (~31% of those with aura) 1:
- Unilateral paresthesia (pins and needles)
- Numbness spreading gradually in face or arm
Less common aura manifestations 1:
- Aphasic speech disturbance
- Brainstem symptoms (dysarthria, vertigo)
- Motor weakness (hemiplegic migraine)
- Retinal symptoms (monocular visual disturbances)
Critical Diagnostic Distinctions
Important caveat: The gradual spread of aura symptoms over ≥5 minutes and their successive occurrence distinguishes migraine from TIA, where symptoms have sudden, simultaneous onset 1. This temporal pattern is crucial for avoiding misdiagnosis.
Clinical Context
The term "vascular headache" encompasses episodic, unilateral, pulsatile, severe pain patterns 2. These headaches typically begin at or around puberty, are more common in women, and frequently occur with a positive family history 1. The underlying mechanism is now understood to be neurogenic rather than purely vascular, with vascular changes representing secondary phenomena 3.
