I don't think panic attacks is something that can be cured. there are an infinite number of things that people can be afraid of on top of that there are so many problems in life be it physical, mental or natural disasters in which people can experience a bad experience causing PTSD and panic attacks is one of the symptoms for that. Even though there is no real cure for this there are ways to learn how to cope with what is causing the panic attacks such as therapy, self help books and classes that teach about panic topics/disorders and anxiety.
