    AbstractThe Virchow-Robin spaces (VRs) in the cerebral glymphatic system play a vital role in waste clearance from the brain. Simple febrile seizures (SFS) are a common type of seizures marked by an inappropriate fluid exchange. The mechanism of evident differences in glymphatic function among SFS with varying seizure duration is unknown. Therefore, the goal of this study was to see whether there were any variations in glymphatic function among SFS based on seizures duration. We retrospectively studied 30 children with SFS lasting more than 5 minutes (SFS > 5M), 40 children with SFS lasting 5 minutes or less (SFS ≤ 5M), and 35 healthy controls aged 6 to 60 months who underwent magnetic resonance imaging (MRI). A custom-designed automated method that used T2-weighted imaging (T2WI) to segment the visible VRs. The VRs metrics were measured and compared studied groups. The VRs metrics, seizure duration the time gap between seizure onset and MRI scan were studied as well. VRs counts were lower (P < .001) in the SFS ≤ 5M (445.80 ± 66.10) and the control (430.77 ± 182.55) groups in comparison to SFS > 5M (642.70 ± 100.62). Similar results were found for VRs volume (VRsvol_SFS > 5M, 8514.63 ± 835.33mm3, VRsvol_SFS ≤ 5M, 6390.43 ± 692.74 mm3, VRsvol_control, 6048.37 ± 111.50 mm3; P < .001). However, in the SFS ≤ 5M, VRs measurements were lower than in the SFS > 5M (P < .001). VRs measurements were positively connected with seizure duration and inversely correlated with the course following seizure onset and MRI scan time in both SFS groups. SFS are positively correlated to glymphatic dysfunction since they cause enlarged VRs; additionally, VRs can be used as a biomarker in SFS > 5M and contribute to the mechanism.Copyright © 2022 the Author(s).
