[Nutritional factors associated with migraine]. / Factores nutricionales asociados a la migraña.

Introduction: Migraine is a chronic, highly prevalent, multidimensional, and complex disorder, influenced by genetic and environmental factors, among which is the diet. Medical treatments are partially effective, and that makes necessary to complement them with other therapeutic strategies. The nutrition plays a prevalent role. We will review dietary factors that have been linked to migraine and therapeutic nutritional guidelines about it: elimination, integral, ketogenic, epigenetic and hypocaloric diets, as well as diets that interest fatty acids, sodium, vitamins, and the gut-brain axis. To date, the evidence of the efficacy of nutritional treatments for migraine is not widespread and it is necessary to advise our patients about patterns consistent with nutritional general recommendations.

Los tratamientos médicos son parcialmente eficaces y se hace necesario complementarlos con otras estrategias terapéuticas, entre las que la nutrición juega un papel prevalente. Revisaremos los factores dietéticos que se han vinculado con la migraña y las pautas nutricionales terapéuticas más estudiadas: dietas de eliminación, integrales, cetogénicas, epigenéticas e hipocalóricas, así como dietas que implican a los ácidos grasos, el sodio, las vitaminas y el eje intestino-cerebro. A día de hoy la evidencia de la eficacia de los tratamientos nutricionales para la migraña no es amplia, de modo que aún en estos pacientes conviene aconsejar patrones dietéticos coherentes con las recomendaciones nutricionales generales.

The Single Word Auditory Comprehension (SWAC) test: A simple method to identify receptive language areas with electrical stimulation.

OBJECTIVES: Resective surgery for medically refractory epilepsy in proximity to speech receptive areas requires balancing adequate resection of the epileptogenic zone for optimal seizure control with preservation of function. We develop a simple test (Single Word Auditory Comprehension or SWAC) to localize speech receptive areas by evaluating patients' ability to comprehend a single word. METHODS: Patients were studied during presurgical or intraoperative assessment for epilepsy with intracranial electrodes. They were asked to listen to a common word (target word) and to describe what it meant without saying the target word. Electrical stimulation (trains of biphasic 2-ms pulses, 50 Hz for 3 s) was delivered while the patient listened to the target word, not while the patient explained the meaning of the word. In six patients, SWAC test was carried out during extraoperative chronic recordings, and in one patient in the operating theater under local anesthesia. RESULTS: Among the 7 patients where the test identified deficits, 6 underwent resection (4 temporal, 1 supramarginal, and 1 occipital). Two patients showed temporary minor speech deficits after resection. No patient showed permanent speech deficits after resection. CONCLUSION/SIGNIFICANCE: The SWAC test is reliable, simple and fast to implement, and suitable for intraoperating mapping. It could be used as a simple initial test to identify receptive language areas where more complex additional tests can be performed.
