“…However, this hypothesis is speculative and requires further verification. Our results appear to be at variance with those of Ruegg et al who conducted a study in Basel, Switzerland, and characterized high relative air humidity as a protective factor for epileptic seizures. However, given that their study population comprised patients admitted to an intensive care unit with status epilepticus resistant to therapy, results from the Swiss study cannot be compared directly to ours.…”

“…However, due to the small size of the study cohort and methodologic issues, the significance of both studies is clearly limited. Two other studies were performed in a highly selected group of patients, that is, patients with status epilepticus resistant to therapy or hospitalized epileptic patients during tapering of antiepileptic medication, which again limits the significance of the results. Thus the influence of weather on the general risk of epileptic seizures is unclear and has not been evaluated in a comprehensive epidemiologic study.…”

Weather as a risk factor for epileptic seizures: A case‐crossover study

Low atmospheric pressure and high relative air humidity are associated with an increased risk for epileptic seizures, whereas high ambient temperatures seem to decrease seizure risk. Weather-dependent seizure risk may be accentuated in patients with less severe epilepsy. Our results require further replication across different climate regions and cohorts before reliable clinical recommendations can be made.

“…Several observations suggest that the lunar tidal force affects certain biochemical processes [49]. A few studies have evaluated circalunar patterns of seizure occurrence [50,51]. Furthermore, Transcranial Magnetic Stimulation (TMS) initiates EEG slowwave activity in sleeping volunteers, suggesting that electromagnetic exposures may influence brain activity and sleep characteristics [52].…”

To date, only a few and conflicting analyses have been published about the association between lunar phases and sleep. Our aim was to analyze the relationship between lunar phases and sleep characteristics. Methods:In this retrospective, cross-sectional analysis data from 319 patients who had been referred for sleep study were included. Individuals with apnea-hypopnea index≥15/h were excluded. Sociodemographic parameters were recorded. All participants underwent one-night standard polysomnography. Associations between lunar cycle (new moon, full moon and alternate moon) and sleep parameters were examined in unadjusted and adjusted models.Results: 57% of patients were males. Mean age for men was 45±14 years and 51±12 years for women. 224 persons had their sleep study done during alternate moon, 47 during full moon and 48 during new moon. There were no significant differences regarding age and gender between groups.Full moon was associated with lower sleep efficiency (median(%) [ Conclusion:Our results are consistent with a recent report and the widely held belief that sleep characteristics may be associated with the full moon.

“…Class III trials support efficacy and safety of valproic acid as first-line therapy (26,27), second-line therapy (31,32), and refractory therapy (66). Evidence for use of levetiracetam and lacosamide is limited to retrospective studies (67)(68)(69)(70)(71)(72). Given the favorable pharmacokinetic characteristics and adverse-effect profiles for these medications compared with fosphenytoin and phenobarbital, comparative trials of these medications as second-line therapy will provide vital evidence to improve future treatment of convulsive status epilepticus.…”

CONTEXT: The optimal pharmacologic treatment for early convulsive status epilepticus is unclear. OBJECTIVE: To analyze efficacy, tolerability and safety data for anticonvulsant treatment of children and adults with convulsive status epilepticus and use this analysis to develop an evidence-based treatment algorithm. DATA SOURCES: Structured literature review using MEDLINE, Embase, Current Contents, and Cochrane library supplemented with article reference lists. STUDY SELECTION: Randomized controlled trials of anticonvulsant treatment for seizures lasting longer than 5 minutes. DATA EXTRACTION: Individual studies were rated using predefined criteria and these results were used to form recommendations, conclusions, and an evidence-based treatment algorithm. RESULTS: A total of 38 randomized controlled trials were identified, rated and contributed to the assessment. Only four trials were considered to have class I evidence of efficacy. Two studies were rated as class II and the remaining 32 were judged to have class III evidence. In adults with convulsive status epilepticus, intramuscular midazolam, intravenous lorazepam, intravenous diazepam and intravenous phenobarbital are established as efficacious as initial therapy (Level A). Intramuscular midazolam has superior effectiveness compared to intravenous lorazepam in adults with convulsive status epilepticus without established intravenous access (Level A). In children, intravenous lorazepam and intravenous diazepam are established as efficacious at stopping seizures lasting at least 5 minutes (Level A) while rectal diazepam, intramuscular midazolam, intranasal midazolam, and buccal midazolam are probably effective (Level B). No significant difference in effectiveness has been demonstrated between intravenous lorazepam and intravenous diazepam in adults or children with convulsive status epilepticus (Level A). Respiratory and cardiac symptoms are the most commonly encountered treatment-emergent adverse events associated with intravenous anticonvulsant drug administration in adults with convulsive status epilepticus (Level A). The rate of respiratory depression in patients with convulsive status epilepticus treated with benzodiazepines is lower than in patients with convul-
