“…Increased gray matter frontal cortex volume, 21 decreased frontal gray matter, 22 and both regional increased and decreased regional white matter volumes 8 have all been reported. Thalamic findings in IGE include anterior thalamic gray matter volume reductions, 8,21,22 increased anterior thalamic gray matter density, 7,23,24 decreased thalamic volume, 11 and no thalamic volumetric differences. [25][26][27] Although studies reporting thalamic abnormalities conflict, these studies consistently report that differences lie in the anterior and medial thalamus, a region strongly connected to the prefrontal cortex via the anterior thalamic radiation.…”

“…Since Gloor et al 3 first suggested that an abnormal cortical response to thalamocortical afferents might be responsible for generalized seizures, there is considerable evidence that thalamocortical networks are pathophysiologic in IGE. [4][5][6] Previous imaging studies have shown consistent structural and functional thalamic and cortical abnormalities, particularly in the frontal lobes, 7,8 and thalamofrontal white matter connectivity. 5 The thalamus and frontal lobes have extensive anatomic interconnectivity with bidirectional pathways 9 and both structures are involved in generalized spike wave discharges associated with IGE.…”

“…Children with idiopathic generalized epilepsies have also shown distributed patterns of abnormality affecting the thalamus and frontal lobe. [17][18][19][20][21] It is not known whether the structural alterations developed during a vulnerable phase of cerebral development or are the cumulative effects of recurrent seizures 22 or are a combination of these factors acting synergistically. 11 To determine whether antecedent neurobiologic alterations are present, assessment could be performed in a population of patients with newonset seizures, which would exclude the confounding effects of recurrent seizures and long-term antiepileptic medications on the brain.…”
