Such a spasm may bethe initial feature of a Jacksonian fit. Grimacing is the feature ofall severe epileptic attacks that most impresses onlookers. In limitedcortical lesions in the face-centers the spasm may be confined to a por-. Fig. 43.—Diagram of facial nerve passing throughthe petron.

DISEASES OF THE FACIAL XERVE. 123 tion of the face, as to the angle of the mouth or to the eyelids and cortical spasms are usually attended by mental symptoms, such asan aura, confusion, or unconsciousness, and are practically independent ofcircumstances and surroundings. Feelings of apprehension and a dis-tressed appearance commonly attend them. Their frequency is they occur singly, at long and irregular intervals. An explosion,a sort of status, may take place so that the face is convulsed for manyminutes or even hours, and then returns to a normal quietude, perhapsmarked by a slight paresis or even by a distinct weakness, which is im-portant and should always be sought.
