“…The highest incidence of all NORSE cases in summer is consistent with previous publications that found a higher frequency of non‐convulsive SE in summer or higher admission rates of children for seizures during the warmest months 15,16 . However, in our study, most patients had convulsive seizures or convulsive SE at some point, and the temperature was not different on the day of SE onset compared to the average values estimated in the 1985–2015 period.…”

Although those data have to be interpreted with caution due to the acceleration of global warming in the last decade, we might still consider that the seasonality of NORSE is not explained by differences in temperature.…”

“…13 In Turkey, a higher number of children were admitted to the emergency department for epileptic seizures during times of increased humidity and temperature. 15 Similarly, another study conducted in the northern hemisphere found that the frequency of non-convulsive SE was higher in the summer compared to the other seasons. 16 This study used a large cohort of patients from multiple sources to investigate if the occurrence of NORSE varies over the year.…”

The seasonality of new‐onset refractory status epilepticus (NORSE)

et al. 2023

The etiology of new‐onset refractory status epilepticus (NORSE), including its subtype with prior fever known as FIRES (febrile infection‐related epilepsy syndrome), remains uncertain. Several arguments suggest that NORSE is a disorder of immunity, likely post‐infectious. Consequently, seasonal occurrence might be anticipated. Herein we investigated if seasonality is a notable factor regarding NORSE presentation. We combined four different data sets with a total of 342 cases, all from the northern hemisphere, and 62% adults. The incidence of NORSE cases differed between seasons (p = .0068) and was highest in the summer (32.2%) (p = .0022) and lowest in the spring (19.0%, p = .010). Although both FIRES and non‐FIRES cases occurred most commonly during the summer, there was a trend toward FIRES cases being more likely to occur in the winter than non‐FIRES cases (OR 1.62, p = .071). The seasonality of NORSE cases differed according to the etiology (p = .024). NORSE cases eventually associated with autoimmune/paraneoplastic encephalitis occurred most frequently in the summer (p = .032) and least frequently in the winter (p = .047), whereas there was no seasonality for cryptogenic cases. This study suggests that NORSE overall and NORSE related to autoimmune/paraneoplastic encephalitis are more common in the summer, but that there is no definite seasonality in cryptogenic cases.
