Potential risk of Migraine

 

qEEG screening

Service code s9021

Please note that screening does NOT result in a medical diagnosis; it gives a probabilistic estimate of risk. In other words, the screening gives information on the presence of a pattern in the qEEG that is often – but not always – found in persons with a history of a particular condition.

Short description

Usually, migraine results in the episodes of severe or moderate headache (which is often one-sided and pulsating) lasting between several hours to several days, accompanied by gastrointestinal upsets, such as nausea and vomiting. Visual aura (disturbance of vision) is the most common of the neurological events that usually precedes the headache. The somatosensory experience (a feeling of pins-and-needles or numbness) in the hand and arm as well as in the ipsilateral nose-mouth area or tongue is also common.

It is proposed that a phenomenon known as neuro-cortical spreading depolarization is responsible for the disorder. In cortical spreading of depolarization, electrical activity is depressed over an area of the cortex of the brain. This situation results in the release of inflammatory mediators leading to irritation of cranial nerve roots, especially the trigeminal nerve, which conveys the sensory information for the face and much of the head.

Scientific studies demonstrated that qEEG screening may help to objectively assess the brain’s electrical activity typical for a migraine.

Results

By performing this qEEG screening you will get the information on:

  • whether you have a qEEG pattern typical for migraine and
  • the potential extent of its severity.

Notes:

  • The results of qEEG analysis are put in context of published scientific studies, the individual’s health history, complaints, symptoms and psychometric and other evaluations (if available).
  • Present psychotropic medication use may affect the results.
