My 14 month old niece has a tendancy to boucne and then go very rigid with her eyes closed and seems to be in a semi concious state. It is quite worrying to witness and she has to be picked up out of her chair or where ever she is sitting to relieve the rigitity.Is it something that we should seek medical help with or is it just brought on by her constant bouncing?
Is this anxiety provoking events as breath holding? Is it episodic tantrums? Is it paroxysmal dyskinetic? Is it a seizure phenomenon? All these could be answered only when you clip a video and show it to an expert. If she is off consciousness, then a EEG is needed, if symptoms occur without any cause.
