What are Primary Headaches?
Primary headaches are headache disorders not caused by another medical condition such as a tumor, infection, stroke, or sinus disease. Instead, the headache itself is the condition. These headaches are related to how the brain, nerves, muscles, and blood vessels function and interact—particularly within the head, face, jaw, and neck. Primary headaches are common, often recurrent, and can be disabling, but they are not dangerous when properly diagnosed.
The Four Categories of Primary Headaches
Primary headaches are divided into four major categories:
1. Migraine
A neurologic headache disorder characterized by moderate to severe head pain, often with nausea, light sensitivity, sound sensitivity, and sometimes visual symptoms.
2. Tension-Type Headache
The most common headache type, typically described as pressure or tightness around the head, often linked to muscle tension in the head, jaw, neck, and shoulders.
3. Trigeminal Autonomic Cephalalgias (TACs)
A group of rare but severe headaches marked by intense, one-sided pain with prominent autonomic symptoms such as tearing, nasal congestion, or eyelid drooping.
4. Other Primary Headache Disorders
A collection of 10 less common headache conditions that do not fit into the above categories but are still primary headaches.
