Migraine and the brain



                                

Migraine

migraine is a type of head-pain which is  intense and continuous, generally followed by  neurological warning signals.The searing  discomfort caused by migraines can last for  hours and as the case maybe, several days.
                             
 Migraine Cycle

Migraine emanate from high-strung aberrant neurons and germinal cells.Simply put, the excruciating pain is caused     when non-naturally occurring neurons in the brain becomes     impulsive. Reasons for this action include: 


  •        Hypomagnesaemia (low magnesium)
  •        Abnormal calcium channels on the surface of the neuron
  •        Mitochondral irregularities
  •        Congenital brain chemical abnormalities 
Recent findings on migraine shows that the Glial cells (which provides support and protection for the neurons) also transmit pains.
The trigeminal nerves (a nerve responsible 
for sensation in the face and motor 
functions such as biting and chewing) begins in the brain stem (towards the rear of the trigeminal nucleus) and pass through the teeth, face, eyes, forehead, blood vessels and sinuses. These movement give rise to excitable neurons.

Messages from the activated cells in the trigeminal nucleus of the brain stem causes the release of brain chemicals which causes inflammation and peripheral sensitization. As the invasion continues it maturate into central sensitization (pain response from stimuli which do not normally provoke pain).When central sensitization becomes advanced, it can affect areas beyond the head, and simple touch on the arms or shoulder can be perceived as painful.

                                                     Types of migraine




There are two main categories of migraine

Migraine without aura 

This is the most common type  migraine which affects one side of the brain. symptoms associated with this type of migraine are; confusion, excruciating headache, fatigue ,mood swing, blurred vision and high sensitivity to sound, smell and light. The regular use of symptomatic medications usually worsen this type of migraine.Migraine without aura attacks mostly last between four hours to three days and recurrent few times in a year.

Migraine with aura

This usually occur without an headache.It causes partial or total blindness.Other symptoms include: trouble speaking, muscle weakness, nausea, loss of appetite and abnormal sensation.

Other types of migraine include
  1. Hemiplegic migraine
  2. Migraine without headache
  3. Migraine with brain stem aura
  4. Retinal migraine
  5. Chronic migraine
                                             Early migraine symptoms

Symptoms that occur few days before a migraine attack are
  • Uncontrollable yawning
  • Depression
  • Stiffness around the neck
  • Hyperactivity
  • Irritability
  • Food cravings
  • Constipation
                                      General symptoms include

  1. Fatigue
  2. Dizziness
  3. Moderate to severe pain (often described as pounding, throbbing pain) that can affect the whole head, or can shift from one side of the head to the other
  4. Sensitivity to light, noise or odors
  5. Blurred vision
  6. Nausea or vomiting,stomach upset ,abdominal pain 
  7. Loss of appetite
  8. Sensations of being very warm or cold
  9. Paleness
  10. Fever in rare cases
  11. Bright flashing dots or lights, blind spots, wavy or jagged lines
