What is Migraine

A migraine is a headache that is characterized by a throbbing or pulsating feeling in an area of the head. It can cause you to feel sick, you may vomit and you may find that you are quite sensitive to light and loud sounds. It is very likely that you will be focused on finding a dark, quiet place where you can lie down.

What is a Migraine Cause

A migraine is a type of vascular headache caused by the enlargement of blood vessels. This vasodilatation as it is called causes chemicals to be released from nerve fibers which coil around the large arteries of the brain. When the nerves are stretched the chemicals cause inflammation and pain which further enlarges the arteries so that the pain becomes intense.
A drop in the levels of serotonin is believed to be responsible for the widening of the blood vessels which is one of the main migraine causes.

Migraine Headache

Migraine headaches activate the sympathetic nervous system. This is the system in the body which controls basic responses to stress and pain and which triggers the 'fight or flight' response. Often the pain associated with a migraine is located in the forehead region, around one eye or it can be on both sides of the head.

Migraine Definition

A migraine headache is defined as being a neurological disorder which is characterized by moderate to severe headaches and feelings of nauseousness. A migraine headache can develop due to some type of trigger' such as stress, hunger and fatigue. There is some proof that potential migraine triggers can be poor air quality and lighting. Other triggers are hormonal changes and certain foods and drinks such as cheeses, chocolates, coffees, teas and alcohol. Also, low levels of magnesium can trigger migraine headaches. Studies have proven that just before and after a migraine, magnesium levels decrease which causes the nerve cells in the brain to misfire.

Stress
