Background hypothalamus hamartomas(HHs)are rare,congenital,tumor-like,and nonprogressive malformations resulting in drug-resistant epilepsy,mainly affecting *** seizures(GS)are an early hallmark of epilepsy with *** aim of this study was to explore the disease progression and the underlying physiopathological mechanisms of pathological laughter in *** We obtained clinical information and metabolic images of 56 HH patients and utilized ictal semiology evaluation to stratify the specimens into GS-only,GS-plus,and no-GS subgroups and then applied contrasted trajectories inference(cTI)to calculate the pseudotime value and evaluate GS *** logistic regression was performed to identify neuroimaging-clinical predictors of GS,and then voxelwise lesion network-symptom mapping(LNSM)was applied to explore GS-associated brain *** cTI inferred the specific metabolism trajectories of GS progression and revealed increased complexity from GS to other seizure *** was further validated via actual disease duration(Pearson R=0.532,P=0.028).Male sex[odds ratio(OR)=2.611,P=0.013],low age at seizure onset(OR=0.361,P=0.005),high normalized HH metabolism(OR=−1.971,P=0.037)and severe seizure burden(OR=−0.006,P=0.032)were significant neuroimaging clinical *** revealed that the dysfunctional cortico-subcortico-cerebellar network of GS and the somatosensory cortex(S1)represented a negative *** This study sheds light on the clinical characteristics and progression of GS in children with *** identified distinct subtypes of GS and demonstrated the involvement of specific brain regions at the cortical–subcortical–cerebellar *** valuable results contribute to our understanding of the neural correlates of GS.
