15 Nov Reader’s Mail: Seek Professional Help for Change in Headache Patterns
Q. I have had migraines for more than 30 years and am successfully managing with them with abortives. Until recently they were mainly without aura, but lately I have been getting several auras a week, but without a headache. Can you explain what is happening and provide any suggestions for treatment? I also get scalp pain that sometimes progresses to a headache and sometimes not. I usually treat that with a non-steroidal anti-inflammatory medication.
I would appreciate any comments or suggestions you have on either of these issues.
A. Auras are electrical events in the brain called spreading cortical depression. About 25% of migraines are associated with an aura. Usually, auras precede the headache phase of a migraine. People can also get auras without a headache or at times with a low-grade headache. However, in your case these auras represent a change in your headache pattern, and it is very important that you talk to your healthcare professional to determine if you need medical testing.
