Ayrica basvuru sirasindaki norolojik inceleme bulgulan siklik sirasina gore dizartri (%91), yuruyus bozuklugu (%75), risus sardonicus (%72), distoni (%69), rijidite (%66), tremor (%60), disfaji (%50), korea (%16), atetoz (%14) ve nadir olarak da nobetler ve piramidal bulgular olarak bildirilmistir (5).
This pattern may be repeated several times, bringing about a tetanic spasm in which the chest is fixed, the neck stiffens, the face twists into a curious grin, the so-called risus sardonicus, and death brings the suffering to an end.
The impact on the facial muscles produces a particular characteristic feature called risus sardonicus, or "sardonic grin," in which the angles of the mouth are drawn down, exposing taught clenched teeth.
