The DSMV (yes, I am that up-to-date), when
discussing the diagnostic criteria for personality disorder, states:
“The essential features of a personality
disorder are impairments in personality (self and interpersonal) functioning
and the presence of pathological personality traits. To diagnose a personality
disorder, the following criteria must be met:
- Significant impairments in self (identity or self-direction) and interpersonal (empathy or intimacy) functioning.
- One or more pathological personality trait domains or trait facets.
- The impairments in personality functioning and the individual’s personality trait expression are relatively stable across time and consistent across situations.
- The impairments in personality functioning and the individual’s personality trait expression are not better understood as normative for the individual’s developmental stage or socio-cultural environment.
- The impairments in personality functioning and the individual’s personality trait expression are not solely due to the direct physiological effects of a substance (e.g., a drug of abuse, medication) or a general medical condition (e.g., severe head trauma).”
I have to say that this definition is
rather harder to understand than the DSMIV criteria, which talks much more
clearly about personality disorder as being “an enduring pattern of inner
experience and behavior that deviates markedly from the expectations of the
individual's culture”. It goes on to talk about how the development of a
personality disorder can be traced back at least to adolescence or early
adulthood.
Personality disorder essentially comes
about as a result of abusive or aversive early life experiences. An event, such
as sexual abuse, interferes with the normal development of personality. In an
effort to cope with such extreme and difficult life experiences, the child or
young person can develop coping strategies which can be perceived as
“abnormal”, but which within the context of that person’s experiences may be
the only way they can survive. A typical example of this is deliberate self
harming through cutting or other means, as a way of relieving the individual of
emotional distress.
While a formal diagnosis of personality
disorder may not be given too commonly, I would estimate that at least 50% of
patients of a typical Community Mental Health Team could be identified as
having at least some of the diagnostic features outlined in the DSMV manual.
It’s certainly the case in the Charwood CMHT.
Traditionally, and unfortunately too often
in the present, the term “personality disorder” has often been used negatively
to describe people whose behaviour others find “difficult” or hard to
understand. Because personality disorders can be difficult and unrewarding to
treat, it has often been the case that doctors make a statement along the lines
of: “This person has a personality disorder. They are therefore not mentally
ill, are untreatable, and should not therefore receive services.”
Unfortunately, one still hears this
sentiment, despite the publication in 2003 of Personality disorder: No longer adiagnosis of exclusion. Published by NIMHE, it remains the principal guidance for
the development of services for people with personality disorder in this
country.
The introduction is immediately
encouraging:
“Personality disorders are common and often
disabling conditions. Many people with personality disorder are able to negotiate
the tasks of daily living without too much distress or difficulty, but there are
others who, because of the severity of their condition, suffer a great deal of distress,
and can place a heavy burden on family, friends and those who provide care for
them.
As with all forms of mental disorder, the
majority of people with a personality disorder who require treatment will be cared for
within primary care. Only those who suffer the most significant distress or difficulty
will be referred to secondary services. This guidance is designed to ensure
that once referred, they receive access to appropriate care.”
The publication states:
“The current 1983 Act is often interpreted
as excluding those with personality disorder from compulsory detention because
of the requirement that the mental disorder be “treatable”. (i.e. treatment is
likely to alleviate or prevent a deterioration in the patient’s condition).
Many clinicians have not seen personality disorder as a mental disorder that is
treatable. This will change with the new mental health legislation … which
removes the treatability clause, and provides a generic description of mental
disorder.”
The report makes frequent reference to the
appropriateness of use of the MHA for the treatment of people with personality
disorder, especially in the forensic area. It has been estimated that up to 80%
of prisoners have some form of personality disorder.
Of course, this was written some years
before the 2007 Act amendments to the 1983 Act were finalised. So what does the
final Act say?
Well, the old definition of “mental
disorder” was as follows: “mental illness, arrested or incomplete development of
mind, psychopathic disorder and any other disorder or disability of mind and
“mentally disordered” shall be construed accordingly”. The Act also included
“mental impairment” and “severe mental impairment”.
The new definition is short and concise,
being merely “any disorder or disability of the mind”.
The revised Act did not in fact remove the
concept of treatability, and in fact detention under Sec.3 requires that
“appropriate medical treatment is available for him”
In an attempt to be helpful Sec.3(4) adds:
“references to appropriate medical treatment, in relation to a person suffering
from mental disorder, are references to medical treatment which is appropriate
in his case, taking into account the nature and degree of the mental disorder
and all other circumstances of his case.”
The Reference Guide (Para 1.16)
adds that “medical treatment” “includes nursing, psychological intervention and
specialist mental health habilitation, rehabilitation and care (as well as
medication and other forms of treatment which might more normally be regarded
as being “medical”)”. It goes on to say that this medical treatment is “for the
purpose of alleviating, or preventing a worsening of, the disorder or one or more
of its symptoms or manifestations”.
So where have I got with answering the
question posed in this post?
I think I’ve established that detention
under the MHA is possible, since a personality disorder is certainly a mental
disorder under the MHA.
I’ve also established that personality
disorder can be regarded as treatable, and that the legal guidance covers the
main sorts of treatment that might be used with personality disorder.
There is therefore no legal reason why
someone with a personality disorder cannot be detained under a section of the
MHA.
But this is not the same as saying that
formal detention should be a routine consideration when an AMHP is presented
with someone with a personality disorder.
At least half of my caseload as
a CMHT worker are people with personality disorders, in particular, emotionally
unstable or borderline personality disorder. I’ve written about some of them on
the blog. I even detained one under Sec.2 on one occasion. (although didn’t
actually admit her).
Some of the people I work with will spend
periods as an inpatient if their emotional instability becomes so severe that
they become dangerous to themselves, although the primary thrust of care
planning is always to keep them out of hospital.
The care plan of one woman I work with, who
frequently engages in self harming and other challenging behaviour,
specifically includes a passage stating that, in a crisis, it is unlikely that
hospital admission would be helpful.
Hospital, and compulsion under the MHA,
does certainly have a place in the treatment of severe personality disorder,
especially in the forensic sphere, but the NIMHE guidance encourages the use of
specialist resources within the community for most people. It is certainly my
experience that it is better to work as much as possible with the wishes of the
person, and to respect any advance decisions they may make about the use of
hospital and compulsion.
But that does not mean that the MHA should
never be used, or only used with forensic cases. I have discussed this issue at
length in my post about the Kerrie Wooltorton case, where a patient with a
personality disorder was allowed to die after drinking antifreeze, on the basis
that that was what she wanted.
In the end, if the requirements for detention are met, then the MHA
should be used, if all alternatives, including informal admission, have been
exhausted. As well as the basic criteria relating to mental disorder of a
nature or degree, for Sec.2, that would be “he ought to be so detained in the
interests of his own health or safety or with a view to the protection of other
persons”, and for Sec.3 “it is necessary for the health or safety of the
patient or for the protection of other persons that he should receive such
treatment and it cannot be provided unless he is detained under this section
and appropriate medical treatment is available for him”.
