Overview

Migraine is a neurological syndrome characterized by altered bodily experiences, painful headaches, and nausea. It is a common condition which affects women more frequently than it does men.

The typical migraine headache is one-sided and pulsating, lasting 4 to 72 hours. Accompanying complaints are nausea and vomiting, and a heightened sensitivity to bright lights (photophobia) and noise (hyperacusis). Approximately one third of people who experience migraine get a preceding aura, in which a patient may sense a strange light or unpleasant smell. Patients often describe triggers they feel precipitate an episode of migraine, such as certain foods and beverages (like chocolate or alcohol), stress or menstruation. In some migraine types there are typical features but the headache remains absent, and in children abdominal pain may be a prominent feature.

Although the exact cause of migraine remains unknown, the most widespread theory is that it is a disorder of the serotonergic control system. Genetic factors may also contribute. Studies on twins show that genes have a 60 to 65% influence on the development of migraine. Fluctuating hormone levels show a relation to migraine in several ways: three quarters of adult migraine patients are female while migraine affects approximately equal numbers of boys and girls before puberty,[citation needed] and migraine is known to disappear during pregnancy in a substantial number of sufferers.

The treatment of migraine begins with simple painkillers for headache and anti-emetics for nausea, and avoidance of triggers if present. Specific anti-migraine drugs can be used to treat migraine. If the condition is severe and frequent enough, preventative drugs might be considered.

The word migraine is French in origin and comes from the Greek hemicrania, as does the Old English term megrim. Literally, hemicrania means "half (the) head".

Comprehend the impact of headache and their treatment on your day-to-day life


What are headaches, there types and where do they occur?


The most common and frequent of ailments, headaches are never termed as 'disease', but may be indicative of certain other underlying problems. However, headaches are fairly common and can be a cause for concern in individuals as it tends to upset a persons daily routine.



The most common types of headaches include tension headache (muscular contraction headache), migraines (vascular headaches) and cluster headache. Cluster headache are generally extremely painful and may occur several times a day or not occur at all for days. In some cases these headaches may require a visit to a medical provider.



There are some rare types of headaches also which deserve a mention here for the simple fact that they affect a sizeable number of individuals from time to time. These headaches include:


  • Idiopathic intracranial hypertension (headache with visual symptoms due to raised intracranial pressure

  • Ictal headache

  • Brain freeze (also known as:ice cream headache)

  • Thunderclap headache

  • Vascular headache

  • Toxic headache

  • Coital cephalalgia (sex headache)

  • Hemicrania continua

  • Rebound headache (medication overuse headache, abbreviated MOH)

  • Spinal headache (post-dural puncture headaches) after lumbar puncture or related procedure that will lower the intracranial pressure

  • Hangover headache (caused by heavy alcohol consumption)



Headaches often result from traction to or irritation of the meninges and blood vessels. Pain, during a headache, transpires in the brain tissues, muscles, nerves and blood vessels around the scalp, face, and neck. Lacking in nociceptors, the brain itself is insensitive to pain. However, the dura mater (the membrane surrounding the brain and the spinal cord), is resplendent with nociceptors. Stimulation of any kind to the dural nociceptors produces headaches.



Tension headaches and their symptoms


Tension headaches are a type of headache that results from contraction of the head and neck muscles. The most common type of headache, it accounts for almost 70% of all headaches that occur. Tension headaches can occur in either sex and at any age; however, it is most common in adults and adolescents.


This type of headache particularly occurs in isolated incidents but may become chronic in some people. Possible causes include:


  • Stress

  • Fatigue

  • Poor posture

  • Eye strain

  • Tobacco and alcohol use

  • Performing an activity with the head held up in one position for a long time

  • Sleeping in a cold room

  • Sleeping in an abnormal position

  • Overexerting oneself

  • Clenching or grinding the teeth

  • Hormonal changes before and after menstrual periods(in women only)



During tension headaches, pain is felt in the generalised area of the head and neck. In addition, the pain may be situated in the back of the head and neck - feeling like an 'extremely tight band". The pain is sometimes accompanied by muscle tightness in the back of the neck also. Nonetheless, tension headache do not last long if treated well in time.



Headache - effective treatment


Treatment for a simple headache is as a rule symptomatic. Over-the-counter painkillers are generally known to work effectively but headaches like migraines may require specific treatment. Headaches in general and migraines in particular may result from specific allergic triggers like stress or unambiguous foods. If known, it is best to avoid these allergic triggers in order to remain ailment free.


If an individual is suffering from chronic headaches, a 'headache' diary could prove to be quite useful as it would help the doctor figure out what kind of treatment is most appropriate for your diagnosis. The easiest way to do this would be to write the dates of headaches on a calendar.


Moreover, maintaining a diary requires making a note of when the pain started and how long it lasted. You must also note down other additional factors pertaining to food and drink that may have triggered your condition, other medicines taken, daily activities, and weather conditions. In the case of women, maintaining detailed information about their periods would also help a lot.


While every individual will require an exclusive form of treatment, over-the-counter pain relievers like paracetamol (Panadol), aspirin (Aspro clear) and ibuprofen (Nurofen) are seen to work effectively in most people with non-chronic headaches; lifestyle changes may also help. But, prescription medicines may be more helpful in people with chronic migraines.
