Let, leave any academical psychic definition of Bipolar disorder, and then look at it. 
What does it look like?
It looks like a potential of having a wide-ranging of awareness. 
But why is it a disorder? Because of it is not normal, or in other words, it is unnormal (unormal). 
Now, just think, there is a range of light's waves which makes colors  that we can see, but it doesn't mean that this is the range of all  light's waves. There are also another light's waves which we can not  see, but they are exactly exist. In compare to Bipolar disorder, people  who has this disorder of course has ability to experience more than  others and they still have common sense and can communicate with  others. 
This is the reason that we can generalize more or less, about another  disorders too. So, now this is the time to ask of  Clinical-Psychology about how to treating with this and also another  disorders.
