Other signs may include numbness in hand and arms, bruising around the mouth, inability to speak or remember names, and feeling of weakness in one side of the body
Migraine without aura: This is the most common type of migraine and does not display the symptoms (described above) that some people notice shortly before a migraine starts.
Causes of Migraine
Migraines are a result of abnormal electrical activity in the brain, causing the brain to be more sensitive to stimulus. In many individuals, an electrical wave causes key nerves to release chemicals (CGRP and other substances), which can cause pain in the nerves and an expansion of blood vessels located around the temple area.
If not treated in a timely fashion, the neurological changes in the brain can lead to: more severe and an, increased regularity of attacks,unresponsiveness to painkillers, and pain around the eye and scalp. An EEG can be used to diagnose abnormal electrical activity in the brain that causes migraine.
A migraine is characterized by a severe headache that is located at the sides or frontal lobe. Sufferers will feel throbbing pain that is worsened by physical activity or movement. Other symptoms may include excessive sweating, an inability to focus, the shivers, stomach pain, and abnormal bowel movements.If left untreated, migraines can last anywhere between 4-72 hours.A number of people may find that certain factors will trigger their migraine headaches. These can include: stress, sleep deprivation, poor sleeping patterns, menstruation, smells or smoke, changes in the weather, heat,sunlight, and certain types of food (fermented food, cheese, wine). Once identified these factors should be avoided to prevent triggering a migraine headache.
