In Psychology and related ones but not psychiatry the brain is descriptive in aa aa ++ ab ab++ etc sometimes other terms are used as power personality and other ones. In normal understanding of the brain in this stream of sciences the brain is descriptive in having obsession of power and its related paradigm. What on physiology of brain works out to be translates to overpossession to this aspect of reality. In bio technology its nothing but a term of love defined in different colours. It percolates down to defining the personality on basic cardinals. Lowest most is mundane to extreme aspects of creativity to obsession of otherworldly cardinals. There does not exist any term of wrong and right or its variants. 

Now if we have to apply psychiatry does it means all such types of persons whether if are equally vulnerable to disorders of brains the reply is big yes but what is natural confusion here how to understand love factor as described the common thread works on reality parameters. The reply is the term love is only graded reality it directly means this faculty of brain is also vulnerable to psychiatry and psychiatric disorders. But the later do not fall under Psychological understanding of the brain and its functions.
