Did you watch the video, or just her picture? It's not impossible that she trained to simulate the way she "blinked", I've known someone who could perfectly isolate one side of her face without affecting the other, but most people can't. It was slow, didn't quite seem as intentional as ponderous. The sticking eyelash thing doesn't seem to hold water, not like her eyelash was pulling on the eyelid, more like one eyelid uncontrollably (and repeatedly) drooping. It looked classically neurological, I'll go and try to find the video again.
