“…Although the predominance of non-lesional epilepsy has been reported in eating reflex epilepsy 8 , it has been previously suggested that structural changes, by acting as a switch between physiological and abnormal brain activity rendering the brain more susceptible to focal reflex seizures; accordingly, eating reflex seizures have also been reported in focal epilepsies of structural origin, such as cortical malformations or hypoxic cerebral lesions 23 , 33 – 35 . Our results correspond to this theory: in patients with no food intake-associated seizures the rate of non-lesional epilepsy was 36.2%, while in those where 50–89% of the seizures were food intake associated, only 25% were be MRI negative (Table 2 ).…”

Various factors have been considered as potential seizure precipitants. We here assessed the temporal association of food intake and seizure occurrence, and characteristics of seizures and epilepsy syndromes involved. 596 seizures from 100 consecutive patients undergoing long-term video-EEG monitoring were analyzed. Preictal periods of 60 min were assessed as to the occurrence of food intake, and latencies between food intake and seizure onset were analyzed. Seizures of temporal origin were highly significantly more frequently preceded by food intake compared to those of extratemporal origin; and were associated with shorter food intake-seizure latency. Seizure precipitation by food intake showed male predominance. Shorter food intake-seizure latency was associated with less severe seizures and less frequent contralateral spread of epileptic discharges. We here show for the first time that not only in specific rare reflex epilepsies but in the most frequent form of focal epilepsy, temporal lobe epilepsy, seizures are significantly precipitated by food intake. Seizure occurrence was increased over a period of up to one hour following food intake, and remained more localized in terms of both ictal EEG spread and as reflected by seizure severity. This finding supports the emerging concepts of ictogenesis, implying a continuum between reflex and spontaneous seizures—instead a dichotomy between them.
