Responds slowly to normal tone of voice	Mild slurring	Mild relaxation	Mild ptosis, less than half the eye	4
Responds only after loud or repeated calling	Slurring	Pronounced relaxation	Glazed, obvious ptosis	3
Responds after mild prodding or shaking	Few recognised words	Pronounced relaxation	Glazed, obvious ptosis	2
No response to mild prodding or shaking	No words	Pronounced relaxation	Glazed, obvious ptosis	1
