The child loses awareness and postural tone, falling to the ground. There may be down-beat nystagmus.
Unlike epilepsy, many PNES patients presenting with total unresponsiveness still retain some form of conscious response, including the natural behavior to protect oneself from harm. This is often reflected by a lack of tongue-biting, urinary and/or fecal incontinence, fall-related trauma, or accidental burns, all of which are significantly less ...
Severe cases of this fear can cause physical reactions that are uncommon in most other fears, specifically vasovagal syncope (fainting).
