| Popis: | The association between emotional stimuli and temporal lobe epilepsy (TLE) is largely unknown. Here, we report the case of a depressed, 50-year-old female complaining of episodes of a “spaced out” experience precipitated by emotional stimuli. Psychogenic non-epileptic attacks were suspected. However, video-EEG coupled with emotional stimuli-provoked procedures and MRI findings of amygdala enlargement, led to the diagnosis of left TLE. Accurate diagnosis and explanation improved her subjective depression and seizure frequency. This case demonstrated that emotional stimuli can provoke seizures in TLE and suggested the involvement of the enlarged amygdala and the modulation of emotion-related neural circuits. Highlights • Emotional stimuli provoked seizures in TLE with amygdala enlargement. • Amygdala enlargement may be associated with the mechanism that elicits seizures. • Optimizing anti-seizure drugs and emotional stimuli management were crucial. • A correct diagnosis may resolve the distress of patients with PNEA and/or TLE. • Thorough investigation is needed before the diagnosis of PNEA is confirmed. |
