Migraine with aura is usually described as a pounding or pulsing headache to one side of the head which can be associated with visual and other sensory changes, light and sound sensitivity, and nausea.
Auras often start about an hour or so before the headache. They aren't just distorted vision, though. They can affect any of your senses.
Blind spots (scotomas)
Vision loss in part of one or both eyes
Seeing zigzag patterns (fortification spectra)
Seeing flashing lights (scintilla)
Seeing, hearing, or smelling things that aren't really there (hallucinations)
Prickling, tingling, or numbness (paresthesia)
Trouble finding words or speaking (aphasia)
The aura usually lasts less than an hour. Some symptoms might continue into the headache phase.
Coping with Aura and Treatment
Treating migraines with aura should consist of a combination of acute and preventative medication. However,if your symptoms have an immediate onset, last longer than 60 minutes or do not completely resolve, medical attention is required. If you experience additional symptoms, such as weakness on one side of the body, change in consciousness or level of alertness, it’s time to see a doctor. Migraine with aura also increases the risk of stroke – because of this, treating other stroke risk factors and avoiding certain medications is important and should be discussed with your physician.
