EEG findings during basilar migraine attacks in children

Ictal and interictal EEG findings in children with migraine

“…Passier et al [36] showed predominant delta activity in the same patient during several attacks and normal activity between them. Ramelli et al [5] showed diffuse polymorphic subdelta-delta activity in two patients with basilar migraine and delta-theta activity predominant over the occipital regions in another two subjects. However, during ictal phase, bilateral high-voltage posterior slowing [37][38][39][40][41][42] and posterior delta slowing associated with spikes and sharp waves or posteriorly predominant sharp and slow wave complexes [43,44] have also been described.…”

“…Other EEG abnormalities have been reported in basilar migraine, a variant of migraine with aura [5,9,30]. In 1961 Bickerstaff [31][32][33] described basilar migraine as a type of migraine with aura, and in 1968 Slatter described the EEG findings during the ictal phase [34].…”

“…Ramelli et al [5] observed marked interhemispheric alpha asymmetry, sometimes associated with an increment of delta activity, during migraine attacks with sensorial or visual aura, while during the acute attack of migraine without aura EEG usually revealed an increase of slow activity on posterior regions. Other EEG patterns, including focal or diffuse slowing that resolves several days after the attack have been described even in rare migraine forms such as hemiplegic or basilar migraine, during ictal phase [4,5].…”

Phenotypic And Electrophysiologic Characterization of a Mouse Model of Fragile X Syndrome

“…This increase was more pronounced in subjects with higher scores on state anxiety. Increase of delta power and coherence were also observed during tonic experimental muscle pain (Le et al 2000), in patients with chronic pancreatitis (Olesen et al 2011), and in migraine patients (Bjork et al 2009;Genco et al 1994;Muellbacher and Mamoli 1994;Ramelli et al 1998). All these data show an increase of delta power associated with pathological states.…”
