Tus síntomas de dolor de cabeza pueden ayudar al médico a determinar su causa y el tratamiento adecuado. La mayoría de los dolores de cabeza no son el resultado de una enfermedad grave, pero algunos pueden deberse a una enfermedad que ponga en riesgo la vida y que requiera atención de urgencia.

Los dolores de cabeza generalmente se clasifican según la causa:

Dolores de cabeza primarios

Un dolor de cabeza primario se debe a hiperactividad o a problemas con las estructuras de la cabeza sensibles al dolor. Un dolor de cabeza primario no es síntoma de una enfermedad oculta.

La actividad química en el cerebro, los nervios o vasos sanguíneos que rodean el cráneo o los músculos en la cabeza y el cuello (o una combinación de estos factores) pueden tener un rol en los dolores de cabeza primarios. Algunas personas también pueden tener genes que los hacen más susceptibles a manifestar estos dolores de cabeza.

The most common primary headaches are:

  1. Cefalea en racimos
  2. Migraña (with and without aura)
  3. Dolor de cabeza tensional (also known as tension-type headache)
  4. Trigeminal autonomic cephalalgia (TAC), such as cluster headache and paroxysmal hemicrania

A few headache patterns also are generally considered types of primary headache, but are less common. These headaches have distinct features, such as an unusual duration or pain associated with a certain activity.

Although generally considered primary, each could be a symptom of an underlying disease. They include:

  1. (for example, chronic migraine, chronic tension-type headache, or hemicranias continua)

Some primary headaches can be triggered by lifestyle factors, including:

  1. Alcohol, particularly red wine
  2. Certain foods, such as processed meats that contain nitrates
  3. Changes in sleep or lack of sleep
  4. Poor posture
  5. Skipped meals
  6. Stress

Secondary headaches

A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions — varying greatly in severity — may cause secondary headaches.

Possible causes of secondary headaches include:

  1. Sinusitis aguda
  2. Arterial tears (carotid or vertebral dissections)
  3. Blood clot (venous thrombosis) within the brain — separate from stroke
  4. Aneurisma cerebral (a bulge in an artery in your brain)
  5. Malformación arteriovenosa cerebral (brain arteriovenous malformation) — an abnormal formation of brain blood vessels
  6. Tumor cerebral
  7. Malformaciones de Chiari (structural problem at the base of your skull)
  8. Conmoción
  9. Deshidratación
  10. Dental problems
  11. Infección del oído (oído medio)
  12. Encefalitis (brain inflammation)
  13. (inflammation of the lining of the arteries)
  14. (acute angle closure glaucoma)
  15. Influenza (gripe) and other febrile (fever) illnesses
  16. Hematoma intracraneal (blood vessel ruptures with bleeding in or around the brain)
  17. Medications to treat other disorders
  18. Meningitis (inflammation of the membranes and fluid surrounding your brain and spinal cord)
  19. Monosodium glutamate (MSG)
  20. Overuse of pain medication
  21. Síndrome posconmocional
  22. Pressure from tight headgear, such as a helmet or goggles
  23. Seudotumor cerebral (increased pressure inside the skull), also known as idiopathic intracranial hypertension
  24. Accidente cerebrovascular
  25. Toxoplasmosis
  26. Neuralgia del trigémino (as well as other neuralgias, all involving irritation of certain nerves connecting the face and brain)

Some types of secondary headaches include:

  1. (a result of pressure-causing headgear)
  2. (commonly called brain freeze)
  3. (caused by overuse of pain medication)
  4. (caused by inflammation and congestion in sinus cavities)
  5. (caused by low pressure or volume of cerebrospinal fluid, possibly the result of spontaneous cerebrospinal fluid leak, spinal tap or spinal anesthesia)
  6. (a group of disorders that involves sudden, severe headaches with multiple causes)
