Investigation of Emotion Regulation Skills in Migraine Patients Using Electroencephalography (EEG) Method

Area of Science:

• Neuroscience
• Psychology
• Medical Research

Background:

• Emotion regulation is crucial for daily functioning.
• Migraine patients often experience difficulties with emotion identification and higher alexithymia.
• Event-related potentials like P300 and N400 offer insights into neural processes during emotion regulation.

Purpose of the Study:

• To investigate the relationship between migraine and emotion regulation.
• To evaluate P300 and N400 brain responses during emotion regulation tasks in individuals with and without migraine.

Main Methods:

• Participants with and without migraine underwent EEG recording during emotion regulation tasks.
• Event-related potentials (P300, N400) were analyzed from specific electrodes (P3, P4, Pz, FC1, FC2, Cz).
• Participants viewed negative/neutral images and then evaluated negative/neutral words after emotion regulation instructions (enhance, suppress, maintain).

Main Results:

• The migraine group showed a higher P300 response to neutral words, while the control group had a higher P300 response to negative words.
• The migraine group exhibited a higher N400 response to negative words (FC1) and neutral words (FC2) compared to controls.
• No significant difference in the effect of emotion regulation commands between groups was observed.

Conclusions:

• Migraine is associated with inefficient attention allocation towards negative stimuli.
• Alterations in semantic processing of emotional words are evident in migraineurs, varying by electrode location.
• These findings highlight distinct neural processing patterns in migraine during emotion regulation.
