  1. FBDS faciobrachial dystonic seizure, GTCS generalized tonic-clonic seizure, FDG-PET 18F-fluorodeoxyglucose positron emission tomography, MRI magnetic resonance image, EEG electroencephalography, SVD small vessel disease, R right, L left, b = bilateral or no laterality, N normal, O presence, N/A not available data
  2. Empty cells indicate normal or absence; In FBDS, O indicates the undecidable laterality due to the insufficient medical records (patients 10 and 11 were described as having twitching along the face and neck, but the laterality whether the FBDS was left or right was not documented)
