FAQ #15
Other Personality Disorders
Question
Many of the symptoms and signs that you describe apply to other personality disorders as well (example: the histrionic personality disorder or the borderline personality disorder). Are we to think that all personality disorders are interrelated?
Answer
The classification of Axis II personality disorders - deeply ingrained, maladaptive, lifelong behavior patterns - in the Diagnostic and Statistical Manual, fourth edition, text revision [American Psychiatric Association. DSM-IV-TR, Washington, 2000] - or the DSM-IV-TR for short - has come under sustained and serious criticism from its inception in 1952.
The DSM IV-TR adopts a categorical approach, postulating that personality disorders are "qualitatively distinct clinical syndromes" (p. 689). This is widely doubted. Even the distinction made between "normal" and "disordered" personalities is increasingly being rejected. The "diagnostic thresholds" between normal and abnormal are either absent or weakly supported.
The polythetic form of the DSM's Diagnostic Criteria - only a subset of the criteria is adequate grounds for a diagnosis - generates unacceptable diagnostic heterogeneity. In other words, people diagnosed with the same personality disorder may share only one criterion or none.
The DSM fails to clarify the exact relationship between Axis II and Axis I disorders and the way chronic childhood and developmental problems interact with personality disorders.
The differential diagnoses are vague and the personality disorders are insufficiently demarcated. The result is excessive co-morbidity (multiple Axis II diagnoses).
The DSM contains little discussion of what distinguishes normal character (personality), personality traits, or personality style (Millon) - from personality disorders.
A dearth of documented clinical experience regarding both the disorders themselves and the utility of various treatment modalities.
Numerous personality disorders are "not otherwise specified" - a catchall, basket "category".
Cultural bias is evident in certain disorders (such as the Antisocial and the Schizotypal).
The emergence of dimensional alternatives to the categorical approach is acknowledged in the DSM-IV-TR itself:
“An alternative to the categorical approach is the dimensional perspective that Personality Disorders represent maladaptive variants of personality traits that merge imperceptibly into normality and into one another” (p.689)
The following issues - long neglected in the DSM - are likely to be tackled in future editions as well as in current research:
- The longitudinal course of the disorder(s) and their temporal
stability from early childhood onwards;
- The genetic and biological underpinnings of personality
disorder(s);
- The development of personality psychopathology during childhood
and its emergence in adolescence;
- The interactions between physical health and disease and
personality disorders;
- The effectiveness of various treatments - talk therapies as well as psychopharmacology.
All personality disorders are interrelated, in my view, at least phenomenologically. We have no Grand Unifying Theory of Psychopathology. We do not know whether there are – and what are – the mechanisms underlying mental disorders. At best, mental health professionals register symptoms (as reported by the patient) and signs (as observed). Then, they group them into syndromes and, more specifically, into disorders. This is descriptive, not explanatory science. Sure, there are a few theories around (psychoanalysis, to mention the most famous) but they all failed miserably at providing a coherent, consistent theoretical framework with predictive powers.
Patients suffering from PDs have many things in common:
- Most of them are insistent (except those suffering from the
Schizoid or the Avoidant Personality Disorders). They demand
treatment on a preferential and privileged basis. They complain
about numerous symptoms. They never obey the physician or his
treatment recommendations and instructions.
- They regard themselves as unique, display a streak of
grandiosity and a diminished capacity for empathy (the ability to
appreciate and respect the needs and wishes of other people). They
regard the physician as inferior to them, alienate him using umpteen
techniques and bore him with their never-ending self-preoccupation.
They are manipulative and exploitative because they trust no one and usually cannot love or share. They are socially maladaptive and emotionally unstable.
- Most personality disorders start out as problems in personal
development which peak during adolescence and then become
personality disorders. They stay on as enduring qualities of the
individual. Personality disorders are stable and all-pervasive – not
episodic. They affect most of the areas of functioning of the
patient: his career, his interpersonal relationships, his social
functioning.
- The patient is not happy, to use an understatement. He is
depressed, suffers from auxiliary mood and anxiety disorders. He
does not like himself, his character, his (deficient) functioning,
or his (crippling) influence on others. But his defences are so
strong, that he is aware only of the distress – and not of its
reasons to it.
- The patient with a personality disorder is vulnerable to and
prone to suffer from a host of other psychiatric disturbances. It is
as though his psychological immunological system has been disabled
by the personality disorder and he falls prey to other variants of
mental sickness. So much energy is consumed by the disorder and by
its corollaries (example: by obsessions-compulsions), that the
patient is rendered defenceless.
- Patients with personality disorders are alloplastic in their
defences. In other words: they tend to blame the external world for
their mishaps. In stressful situations, they try to pre-empt a (real
or imaginary) threat, change the rules of the game, introduce new
variables, or otherwise influence the external world to conform to
their needs. This is as opposed to autoplastic defences exhibited,
for instance, by neurotics (who change their internal psychological
processes in stressful situations).
- The character problems, behavioural deficits and emotional
deficiencies and instability encountered by the patient with
personality disorder are, mostly, ego-syntonic. This means that the
patient does not, on the whole, find his personality traits or
behaviour objectionable, unacceptable, disagreeable, or alien to his
self. As opposed to that, neurotics are ego-dystonic: they do not
like who they are and how they behave on a constant basis.
- The personality-disordered are not psychotic. They have no
hallucinations, delusions or thought disorders (except those who
suffer from a Borderline Personality Disorder and who experience
brief psychotic "microepisodes", mostly during treatment). They are
also fully oriented, with clear senses (sensorium), good memory and
general fund of knowledge.
The Diagnostic and Statistical Manual [American Psychiatric Association. DSM-IV-TR, Washington, 2000] defines "personality" as:
"…enduring patterns of perceiving, relating to, and thinking about the environment and oneself … exhibited in a wide range of important social and personal contexts.

The international equivalent of the DSM is the ICD-10, Classification of Mental and Behavioural Disorders, published by the World Health Organization in Geneva (1992).

Each personality disorder has its own form of Narcissistic Supply:
- HPD (Histrionic PD) – Sex, seduction, flirtation, romance, body;
- NPD (Narcissistic PD) – Adulation, admiration;
- BPD (Borderline PD) – Presence (they are terrified of abandonment);
- AsPD (Antisocial PD) – Money, power, control, fun.
Borderlines, for instance, can be construed as NPDs with an overwhelming fear of abandonment. They are careful not to abuse people. They DO care deeply about not hurting others – but for the selfish motivation of avoiding rejection. Borderlines depend on other people for emotional sustenance. A drug addict is unlikely to pick up a fight with his pusher. But Borderlines also have deficient impulse control, as do Antisocials. Hence their emotional lability, erratic behaviour, and the abuse they do heap on their nearest and dearest.
