Hello, welcome to the forum. Sorry there was a lapse in answering you. Does your partner see a neurologist? I would highly recommend that. There is something called transient ischemic attack or TIA. The episode of staring, having trouble breathing, etc. perhaps would fit that. Copy and paste this link. https://www.stroke.org/en/about-stroke/types-of-stroke/tia-transient-ischemic-attack It is a blockage that causes this and really important to treat. Let me know what you think or if there are any updates since you posted this. Take care
