DISSOCIATIVE
and SOMATOFORM DISORDERS
Individuals
with a dissociative disorder experience a
severe disruption or alteration of their
identity,
memory,
or consciousness. It is based on the unbelievable
things.
Example
A
housewife forgets her name
her entire past life she has
dissociative disorder.
Kinds
of Dissociative disorders
The
types of dissociative disorders
discussed in this lecture are
dissociative amnesia, dissociative
fugue,
dissociative
identity disorder and depersonalized
disorder. Although dissociative disorders
typically involve
disruption
of identity, dissociative amnesia
can involve loss of memory
without loss of
identity.
Diagnosis
of Dissociative Disorders
·
For
centuries, theorists considered
dissociative and somatoform disorders as
alternative forms of
hysteria.
·
However,
the descriptive approach to
classification introduced in DSM-III
(1980) led to the
separation
of dissociative and somatoform disorders
into discrete diagnostic
categories.
·
The
distinction is preserved in DSM-IV-TR
(2000), because the symptoms of the
two disorders
differ
greatly.
1-
The
symptoms of dissociative disorders
apparently involve mental processes
that occur outside of
conscious
awareness.
2-
Extreme
cases of dissociation include a split in
the functioning of individual's sense of
self.
3-
Depersonalization is a
form of dissociation wherein people feel
detached from themselves or
their
social
or physical environment.
4-
Amnesia--the
partial or complete loss of
recall for particular events or
for a particular period of
time.
5-
Brain
injury or disease can cause
amnesia.
6-
But
Psychogenic
Amnesia (psychologically
caused) results from
traumatic stress or other
emotional
distress.
Psychogenic amnesia may
occur alone or in conjunction
with other dissociative
experiences.
7-
It is
widely accepted that
psychogenic fugue and psychogenic
amnesia are usually precipitated
by
trauma,
thus providing another link
between dissociation and
traumatic stress
disorders.
Some
researchers and clinicians
argue that DID is linked
with a past trauma, particularly
with child's
physical
or sexual abuse. The term
psychogenic
was
used in the names of these
disorders- as in
psychogenic
amnesia and psychogenic fugue - to
indicate that the fugue or memory loss is
not
physically
caused.
1-Dissociative
Amnesia
each
of us, throughout our lives,
has forgotten certain things-
a
person's
name, a friend's birthday, the
need to stop at a store on the
way home. Forgetfulness,
however,
is
not yet the same as memory
loss. The person with
memory loss is unable to
recall important
personal
information
too extensive to be viewed in
terms of forgetfulness. When
there is actual damage to
the
brain,
from injury or disease, the
information that isn't
recalled is lost forever.
·
But
in dissociative (psychogenic) amnesia,
the memory system is not
physically damaged, yet
there
is
selective psychologically motivated
forgetting. Often, what has
been forgotten is traumatic
for
the
individual. It can sometimes be retrieved
from memory.
·
There
are two main types of
amnesia: selective and
generalized. In cases of selective
dissociative
amnesia, a
person forgets some but
not of what happened during a
certain period of time.
·
In
contrast to the selective dissociative
amnesia, the person who is suffering
from generalized
dissociative
amnesia forgets one's entire
life history.

2-Dissociative
fugue
the
fugue state involves physical
retreat; during a fugue, the
individual
suddenly
and unexpectedly departs.
Two important features for
diagnosing dissociative
(psychogenic)
fugue are
listed in DSM-IV: a sudden
unexpected travel away from
home or work
with
an inability to recall one's
past, and confusion about personal
identity. Marked confusion
about
personal
identity interferes with
routine daily activities, so in an
effort to adjust and relate
to others, the
person
assumes a new identity. Despite the
new assumed identity,
characteristics of the "old self"
are
recognizable.
Often, complicated behaviors
are carried out during the
fugue. A victim may drive a
long
distance,
find a place to live, obtain
employment, and begin a new
life.
3-Dissociative
identity disorder (DID), also
known as multiple
personality disorder,
is
characterized
by the existence of two or more
distinct personalities in a single
individual.
·
At
least two of these
personalities repeatedly take
control of the person's behavior,
and the
individual's
inability to recall information is
too extensive to be explained by ordinary
forgetfulness.
·
The
original personality especially is likely
to have amnesia for
subsequent personalities, which
may
or
may not be aware of the
"alternates."
·
Examples
1-"Sybil,"
a girl
with sixteen personalities, DID is
characterized by the presence of two or
more distinct
personalities
of personality states within one
individual patterns.
2-The
Three Faces of Eve, who
describe a client, whose three
different personalities virtual
opposites in
terms
of their emotional and behavioral
patterns. Eve White was the
quiet, polite, hard-working,
and
conservative
mother of a young daughter; Eve
Black was seductive, impulsive,
risk-taking, and
adventure-seeking.
Jane, the third personality was a
confident and capable
woman.
4-Depersonalization
disorder is a
less dramatic problem that
is characterized by severe and
persistent
feelings
of being detached from
oneself.
·
Depersonalization
experiences include such sensations as
feeling as though you were in a
dream or
were
floating above your body
and observing yourself as acting.
SOMATOFORM
DISORDERS
·
Do
some individuals really need
a cabinet full of medicines to
deal with their many
ailments, or they
might
benefit more from
psychological counseling?
·
Do we
sometimes respond physically-
for example, by becoming
paralyzed- to psychological
stress?
·
When
mind-body interactions are maladaptive, a
somatoform disorder may result.
Somatoform
disorders
involve physical symptoms, in the
absence of physical illness
for which there is no
adequate
explanation. (Soma
means
body, and somatoform
means
"bodylike." One patient with
a
somatoform
disorder may report being blind
but according to medical
tests, have normal
functioning
eyes.
·
Somatoform
disorders are
problems characterized by unusual
physical symptoms that occur
in the
absence
of a known physical
illness.
1-There
is no demonstrable physical cause
for the symptoms of somatoform disorders.
They are
somatic
(physical) in form only--
their name.
2-All
somatoform disorders involve complaints
about physical symptoms, but
not caused by
physical
impairments.
There is nothing physically wrong
with the patient.
3-The
physical problem is very real in the
mind, though not the body,
of the person with a somatoform
disorder.
4-The
physical symptoms can take a
number of different forms substantial impairment of a
somatic
system,
particularly a sensory or muscular
system. The patient will be
unable to see, for example,
or will
report
a paralysis in one
arm.
5-In
other types of somatoform disorder,
patients experience multiple
physical symptoms
usually
numerous,
complaints about such
problems as chronic pain, upset stomach,
and dizziness.
6-Finally,
some types of somatoform disorder are
defined by a preoccupation
A-
With a particular part of the body
say eyes or stomach
or
160
Abnormal
Psychology PSY404
VU
B-
With fears about a particular
illness.
The
patient may constantly worry
that he or she has
contracted some deadly
disease, for example,
and
the
anxiety persists despite negative
medical tests and clear
reassurance by a physician.
7-People
with somatoform disorders typically do
not bring their problems to
the attention of a mental
health
professional.
Instead,
they repeatedly consult their physicians
about their "physical" problems. This
often leads to
unnecessary
medical treatment.
Kinds
of Somatoform Disorders
DSM-IV-TR
lists five major subcategories of
somatoform disorders:
(1)
Conversion disorder
(2)
Somatization disorder
(3)
Hypochondriasis
(4)
Pain disorder
(5)
Body Dysmorphic disorder
1-
Conversion Disorder
·
The
symptoms of conversion disorder often mimic
those found in neurological diseases,
and they
can
be dramatic.
·
"Hysterical"
blindness or "hysterical" paralysis
are examples of conversion symptoms.
Although
conversion
disorders often resemble neurological
impairments, they sometimes can
be
distinguished
from these disorders because
they make no anatomic sense.
The term conversion
disorder
accurately
conveys the central assumption of the
diagnosis--the idea that
psychological
conflicts
are converted into physical
symptoms.
·
One or
more symptoms or deficits affecting
voluntary sensory or motor
functioning that cannot be
explained
by a neurological or general medical
condition (after appropriate investigation) and is
not
a
culturally sanctioned behavior.
Psychological factors (though
not intentional) are judged
to be
involved
because symptoms are
exacerbated under stress and the
symptoms are useful for
the
patient's
avoidance of stress. The
symptoms or deficits cause clinically significant
distress or
impairment
in social, occupational, other important
areas of functioning.
2-Somatization
disorder
·
Somatization
disorder is characterized by a history of
multiple somatic complaints in the
absence of
organic
impairments.
·
In
order to be diagnosed with
somatization disorder, the patient must
complain of at least eight
physical
symptoms and must involve
multiple somatic
systems.
·
Patients
with somatization disorders
sometimes present their
symptoms in a histrionic
manner--a
vague
but dramatic, self-centered,
and seductive style.
Patients also may exhibit
la
belle indifference
("beautiful
indifference"), a flippant lack of
concern about the physical
symptoms.
161

3-Hypochondriasis
·
Hypochondriasis
is a problem characterized by a fear or
belief that one is suffering
from a physical
illness.
·
Hypochondriasis
is much more serious than
normal and fleeting
worries.
·
The
preoccupation with fears of disease
extends over long periods of
time.
·
In
addition, in hypochondriasis, a thorough
medical evaluation or examination does
not alleviate
the
fear of the disease.
·
Based
on misinterpretations of bodily reactions, the
sufferer is preoccupied with fears of
having a
serious
disease. Though not a
delusion, the fear persists
despite medical evaluations.
The
preoccupation
causes clinical distress of at least
six months duration.
4-Pain
disorder
·
Pain
disorder is characterized by preoccupation with
pain.
·
Complaints
seem excessive and apparently
are motivated at least in
part by psychological
factors.
·
As
with hypochondriasis and
somatization disorder, pain disorder can
lead to the repeated,
unnecessary
use of medical
treatments.
5-Body
dysmorphic disorder
·
Body
dysmorphic disorder is a somatoform disorder in which
the patient is preoccupied
with some
imagined
defect in appearance.
·
The
preoccupation typically focuses on some
facial feature, such as the
nose or mouth, and in
some
cases
may lead to repeated visits
to a plastic surgeon.
·
Preoccupation
with the body part far
exceeds normal worries about physical
imperfections.
162
Abnormal
Psychology PSY404
VU
·
Preoccupation
with and imagined defect in
appearance causes clinically significant
distress or
impairment
in social, occupational, or other
important areas of
functioning.
5-Somatoform
disorders must be distinguished from
malingering,
pretending to
have a somatoform
disorder
in order to achieve some external
gain, such as a disability
payment.
6-A
related diagnostic concern is
factitious
disorder, a fake
condition that, unlike malingering,
is
motivated
primarily by a desire to assume the
sick role rather than a
desire for external
gain.
7-A
rare, repetitive pattern of factitious disorder is
sometimes called Munchausen
syndrome, named
after
Baron Karl Friedrich Hieronymus
von Munchausen, an eighteenth-century
writer known for
his
tendency
to embellish the details of his
life.
Frequency
of Somatoform Disorders
Conversion
disorders are rare, perhaps
as infrequent as 50 cases per
100,000 population. Most
other
somatoform
disorders also appear to be relatively
rare. For example, one
study found a 0.7
percent
prevalence
of body dysmorphic disorder.
Hypochondriasis
is also quite rare, although
less severe worrying about
physical illness is
quite
common.
The lifetime prevalence of
somatization disorder in the United
States is only 0.13
percent.
With
the exception of hypochondriasis, all
other forms of somatoform disorder are
more common
among
women. This is particularly true of somatization
disorder, which may be as much
as10 times
more
common among women than
men.
In
addition to gender, socioeconomic
status and culture are
thought to contribute to
somatization
disorder.
In the United States, somatization is
more common among lower
socioeconomic groups
and
people
with less than a high
school education. It is four
times more common among
African
Americans.
Somatoform disorders typically occur
with other psychological
problems, particularly
depression
and anxiety. Finally, somatization
disorder has frequently been
linked with
antisocial
personality
disorder, a lifelong pattern of irresponsible behavior
that involves habitual violations
of
social
rules.
The
two disorders do not
typically co-occur in the same
individual, but they often
are found in
different
members
of the same family. An obvious--and
potentially critical --biological consideration
in
somatoform
disorders is the possibility of
misdiagnosis. A patient may be
incorrectly diagnosed as
suffering
from a somatoform disorder when, in fact,
he or she actually has a
real physical illness that
is
undetected
or is perhaps unknown. Because
mental health professionals cannot
demonstrate
psychological
causes of physical symptoms
objectively and unequivocally, the
identification of
somatoform
disorders involves a process
called diagnosis
by exclusion.
The
physical complaint is assumed to be a
part of a somatoform disorder only when
various known
physical
causes are excluded or ruled
out. Initially, both Freud
and Janet assumed that
conversion
disorders
were caused by a traumatic
experience. Freud later came to believe
that dissociation and
other
intrapsychic
defenses protected individuals from
their unacceptable sexual
impulses, not from
their
intolerable
memories. In Freud's view, conversion
symptoms were expressions of
intolerable
unconscious
psychological conflicts. In Freudian terminology, this
is the primary
gain of the
symptom.
Freud
also suggested that
hysterical symptoms could produce
secondary
gain,
for
example, avoiding
work
or responsibility or to gain attention
and sympathy.
Social
and cultural theorists offer a
straightforward explanation of the physical symptoms
of
somatization
disorder, hypochondriasis, and pain
disorder. Patients with these
disorders are
experiencing
some sort of underlying psychological
distress. However, they describe
their problems as
physical
symptoms and, to some extent,
experience them that way
because of limited insight
and/or the
lack
of social tolerance of psychological
complaints.

Treatment
of Somatoform Disorders
1-
Cognitive behavior therapy is effective in reducing
physical symptoms in somatization
disorder,
hypochondriasis,
and body dysmorphic disorder.
2-Recent
evidence also indicates that
antidepressants may be helpful in
treating somatoform disorders.
