The animal was diagnosed with "Borderline Personality Disorder", but it looks as if reporters managed to use "traits of a personality disorder". Substantial differences.

Every person has a personality that has varying characteristics, and if one person tends to have more markers present under a certain category of personality types it is coined a disorder, when it interrupts a person's interpersonal relationships.

One of the most severe and disabling of psychiatric illness is paranoid schizophrenia.
I could not imagine a person's state of being if they suffer from Bipolar 1 with Hypermania/Hypermanic states while subsequently being afflicted with Paranoid Schizophrenia. The 2 are difficult enough for one person to manage alone, but together would clearly drive one to a point of insanity, imo.
