Total events: all motor and non-motor paroxysmal manifestations during each 2-month-phase. Motor events: all motor paroxysmal episodes during each 2-month-phase. 6MWT: Total distance walked (metres). 9HPT-D: the best score (seconds) obtained with the dominant hand. 9HPT-ND: best score (seconds) with the non-dominant hand.

GLUT1-DS, glucose transporter type 1 deficiency syndrome; 6MWT, 6 min walk test; 9HPT, nine-hole pegboard test
