Sometimes we can become so informed that we are unaware of the true meaning of ideas and generalities.
Disorders in a psychiatrists eyes are used to recall or stimulate a group of personality traits that all occur at the same time. The mind is far to complicated to simply be labeled bipolar are schizophrenic. It is much deeper than that. Can you display other symptoms outside of your label? YES! "In fact" it is very rare to NOT display other traits that are abnormal to your given label. The purpose of a label is not to say you are sick, crazy, or weird. It is to summarize your basic motives, to help understand, and to help resolve uprising conflicts. It is simply to UNDERSTAND ones thought process.
In more comprehensible terms, an american is an american as a brain is a brain.
Although Americans share relative similar ethnicity, many are influenced or projected by deeper ethnicity. (personality traits)
Mental example - A brain with a general identification of schizophrenia, may have a deeper influence of bipolar cognition. You may have layers of "disorders" (a term which I despise) so in a non-bias sense you have many layers of orders, such as a general order of schizophrenia ect.
Physical example - An American with a general identification of "black" may have deeper influences of European. It can branch even further into african, asian, latino ect, just as a mental order may branch off into other categories of orders
In controversy, but of little meaning to my purpose...
