Hi I am the brother of a sister who has panic attacks. She has only had them two times but these panic attacks have recently started happening and this worries me because this may be something she lives with for her entire life. When she has had the panic attacks she hyperventilates starts crying and she keeps saying shes scared. She usually falls asleep to calm down, but she doesn't remember what happens when she wakes up. I have researched a little but I haven’t read anywhere about people forgetting what happened during their panic attacks. Is forgetting a panic attack a symptom of panic attacks or is she having different medical condition.
