SIGNS AND SYMPTOMS OF MIGRAINE:

Migraine is a typical type of headache which is divided into four phases.

Though the headache consists of four phases all the patients don’t compulsorily experience all four phases.

CAUSES OF MIGRAINE:

Migraine is a complex phenomenon which is a result of environmental and genetic factors.

Near about two third of migraine, causes are hereditary.

Some psychological conditions are also responsible for migraines such as anxiety, depression and bipolar disorders.

  1. Genetic factors:

Migraine with an aura phase is more common to adopt genetically than migraine without an aura phase.

A study has shown that there are four autosomal genes which are responsible for the genetic transmission of migraine progeny to progeny.

Trigger factors:

A migraine attack is most commonly commences by certain triggers.

Triggers for migraine may be of different types such as physiological factors and environmental factors.

Many things like certain foods, fatigue, alcohol and weather can be responsible for a migraine attack.

MSG used in many junk foods is reported as the biggest trigger factor for a migraine attack.

Other food items like alcoholic beverages, chocolate, cheese, and processed meat contain tyramine, which is believed to be a trigger factor for migraine.

ENVIRONMENTAL FACTORS:

The clinical studies for environmental factors causing migraine are not sufficient despite, bad indoor air and light,  might trigger migraine, although not proved yet.

PATHOPHYSIOLOGY OF MIGRAINE:

There are some differences between researchers regarding the pathophysiology of migraine.

Some believe it is a neurological disorder while others assume it is a neurovascular disorder in which blood vessels are playing an important role.

DIAGNOSIS OF MIGRAINE

Diagnosis of migraine is quite interesting..

Time: 4 hours.

Duration: 3 days.

Symptoms: 2 in no. (From. Unilateral headache, pulsating, pain intensity moderate to severe, triggered by physical activity.)

Symptoms: 1 in no. ( from. Nausea or Vomiting, Photophobia or photo phobia.)

TREATMENT FOR MIGRAINE:

The phrase, prevention is better than cure.

This is the best example of a migraine.

People may avoid migraine attacks by avoiding trigger factors.

As it’s treatment is concerned,

Migraine can be treated by

Non-steroidal anti-inflammatory drugs such AS diclofenac, ibuprofen and aspirin. Along with analgesics, anti-emetic drugs such as sumatriptan can be used in severe migraine attacks
