Today is Theory Thursday, and the first entry in a multiple part series on autism comorbidities. The first and third Thursday of each month will be an educational fact-based entry on one of several disorders which are comorbid with autism. The second and fourth Thursday will be a post from a parent of a child with, or an individual with, an ASD diagnosis and the comorbidity discussed the week before. For more information see Reader Request. The first comorbidity: Migraine Disorder.
Headaches can be divided into three main categories: Tension, Migraine, and Cluster. Generally, the least painful and easiest to treat is the Tension headache; for most individuals it can be cured with a Tylenol and a heating pad. The most excruciating is the Cluster headache, which is a series (or cluster) of ice-pick-like stabs directly behind the eye. These tend to occur for about a week, and then not appear again for months. Then there is the Migraine. Four things separate the Migraine from the Tension headache:
- more severe pain that doesn’t respond to OTC medication
- Sensitivity to lights (photophobia)
- Sensitivity to sound (phonophobia)
- Nausea/ Vomiting
For some individuals, a migraine is preceded by an aura, which may involve flashing or rotating colors, dots before the eyes, or intense smells or tastes which cannot be attributed to an item in the environment.
A migraine can last anywhere from 4 to 72 hours, with most lasting roughly 24. During this time it is often impossible for the individual to work, eat, speak, or perform their typical daily functions. The best place for an individual with a migraine? Lying down in a dark room with the lights off and the door closed, preferably one near a night-light lit bathroom.
The treatments for migraine are numerous and vary based upon the primary symptom of the Migraine. If the most debilitating aspect is the pain, often a triptan such as Relpax or Imitrex, now often taken with caffeine and naproxen to increase the effect is prescribed. If nausea and vomiting are the main issue, or prevent the ingestion of pain medication, Reglan and Thorazine are often used first. When there is a high frequency of migraine headaches (4 or more per month) a preventative is often prescribed. Some options include antiepileptics, particularly Topamax, and antidepressants, especially the tricyclics. For those with extreme cases, Demerol, Morphine, and Transcranial Magnetic Stimulation are also possible treatments.
The causes of migraines are even more numerous than the treatments. For an individual to have Migraine Disorder, they must have a genetic predisposition to migraines. Often Migraine sufferers can be found within two generations of a recently diagnosed patient. But environmental triggers also play an important role. A few of the most common are:
- Certain smells (such as cleaning products)
- Flourescent lighting
- Certain foods (particularly wine and cheese)
- Temperature changes
- Hormonal Changes (mostly for women)
- Abnormal Sleep Schedule
As a result, one of the most common steps post-diagnosis is to identify and attempt to eliminate potential triggers by replacing flourescent lighting with incandescent, and going on a restricted diet. If this is ineffective, a preventative is usually prescribed.
If your child is presenting with symptoms of migraine, the pediatrician will often recommend a trip to the neurologist (though most of you probably already have a family neurologist overseeing your autism care). The neuro will run a battery of tests including blood tests for hormone levels and food allergies, CT scans, EEGs, and MRIs to ensure that there is no other identifiable cause for the symptoms (such as a tumor, pseduotumor, or brain injury). Because there is no direct test for Migraine, it is a diagnosis made by the exclusion of other possibilities.
If your child is presenting with Migraine symptoms, it is important that you get help now. Medications have the highest efficacy rate when a person first starts presenting with the disorder, and the quality of life of the patient will improve dramatically after treatment. Additionally, there is increasing evidence that migraines may cause brain trauma in some prone individuals, making it key for you to seek help now.
Next week I’ll be discussing my personal experience with an ASD and Migraine diagnosis, so be sure to check back.
