Headache

What is a headache?

Headache is defined as a pain occurring in any region of the head. Headaches may be isolated to a specific region or may be located in one or both areas of the head, radiate across the head, or have an extremely tight and firm quality. The pain may be sharp, throbbing or dull. The onset of the pain may be gradual or sudden, lasting from less than an hour to several days.

According to the World Health Organization report, approximately half of adults worldwide experience headaches regularly, making them one of the most widespread medical complaints. Most headaches aren’t reflecting a serious health condition and may be relieved by a short rest, some food or water, or over-the-counter pain relievers.

How are headaches classified?

According to International Headache Society classification, headaches are classified into 3 main categories:

• Primary headaches
  Primary headaches are discrete illnesses that are caused by malfunctioning of brain pain-sensitive structures. Changes in chemical activity in the brain, problems with nerves, blood vessels and muscles of the head and neck play a significant role in primary headaches.

  The most common primary headaches include:

  • Migraines
  • Cluster headaches
  • Tension headaches
• Secondary headaches
  Secondary headaches are symptoms that reflect diseases and health conditions that activate pain-sensitive nerves of the head.
  A broad group of medical conditions – varying in severity – can cause secondary headaches, including:
  • Acute sinusitis
  • Ear infections
  • Brain aneurysms
  • Brain tumor
  • Brain injury & post-concussion syndrome
  • Stroke
  • Dehydration
  • Dental problems
  • Encephalitis & Meningitis
  • Glaucoma
  • Hangover
  • High blood pressure
  • Flu
  • Medications & overuse of pain medications
  • Carbon monoxide poisoning
  • Panic disorder and panic attacks
  • Pressure from tight headgear
  • Neuralgias
