Somatization and Conversion Disorder
Trevor A Hurwitz, MD 1
Key Words: somatization, conversion disorder, narcoanalysis, depression, somatoform disorder
S omatization is the tendency of individuals to experience
and communicate psychological distress in the form of so-
matic symptoms and to seek medical help for them (1,2). This
psychological process gives rise to somatoform disorders,
which are typically first seen in nonpsychiatric settings. Their
core features comprise somatic symptoms and signs that can-
not be explained by known disease and that result in social and
occupational impairment. Table 1 lists the clinical criteria.
Symptoms are typically multiple and vague and may refer to
single or multiple body systems or functions. Presentations
include cardiopulmonary, gastrointestinal, genitourinary,
musculoskeletal, and neurologic complaints, as well as pain
and fatigue (3,4). The DSM-IV-TR diagnostic categories that
incorporate the concept of somatization include body
dysmorphic disorder, conversion disorder, hypochondriasis,
somatization disorder, pain disorder, undifferentiated
somatoform disorder, and somatoform disorder not otherwise
specified (5).
In clinical practice, somatoform disorders overlap and most
commonly present with multifocal symptoms and signs (6).
The spectrum of presentations varies from mild to severe and
may be mostly symptom-based (hypochondriasis) or mostly
sign-based (conversion disorder).
Sickness
Somatoform disorders are best understood within the context of
sickness, because patients present as physically sick, which ini-
tially masks the underlying psychiatric disorder. Sickness com-
prises 3 components: disease, illness behaviour, and
predicaments (7,8). Disease is the physical basis of sickness
caused by tissue abnormality or malfunction. Clinically, dis-
ease manifests by observable signs (what the physician sees),
such as edema, hemorrhage, or inflammation, and organ and
system compromise, such as heart failure and paralysis. Illness
behaviour refers to the subjective experiences and behavioural
consequences of disease (what the patient complains of).
Illness behaviour presents as symptoms. These may be nonspe-
cific symptoms, such as fatigue or nausea. Symptoms may also
be referable to specific systems or physical functions, such as
shortness of breath or an inability to move; to specific mental
dysfunctions, such as problems with concentration or sadness;

Somatization is the psychological mechanism whereby psychological distress is expressed
in the form of physical symptoms. The psychological distress in somatization is most
commonly caused by a mood disorder that threatens mental stability. Conversion disorder
occurs when the somatic presentation involves any aspect of the central nervous system
over which voluntary control is exercised. Conversion reactions represent fixed ideas about
neurologic malfunction that are consciously enacted, resulting in psychogenic neurologic
deficits. Treatment is complex and lengthy; it includes recovery of neurologic function
aided by narcoanalysis and identification and treatment of the primary psychiatric disorder,
usually a mood disorder.

or to impaired interpersonal behaviour, such as social with-
drawal or compromised self-reliance. Predicaments are the
psychosocial consequences of illness. These are the negative
and positive interpersonal ramifications arising from being
sick. Predicaments include interpersonal dependence; exemp-
tion from normal domestic and societal obligations such as
work; financial compensation without labour; sanctioning of
symptom-relieving interventions such as medications, includ-
ing the use of narcotic analgesics; granting of special commu-
nity privileges, such as reserved parking, special transport, and
first access; and avoidance of noxious consequences by mitiga-
tion of responsibility, such as being relieved from doing mili-
tary service or serving jail sentences.
Within the context of sickness, somatoform disorders have the
appearance of disease, with the advantages and disadvantages
of illness and predicaments. The conclusion—reached after
appropriate investigation—that there is no disease engenders
distrust and hostility on the part of the medical profession.
Patients are poorly received and treated, and in this negatively
charged physician–patient dynamic, the underlying disease of
psychiatric disorder is often overlooked or ignored.
Pathogenesis of Somatic Symptoms
Somatic symptoms are a psychological defence against men-
tal instability. Like all other intrapsychic defences, symptom
formation reduces intrapsychic distress (9). This is known as
the primary gain (10). Primary gain strives to restore
psychological equilibrium, but at a price. Reality is distorted.
Attention is redirected toward the presenting symptoms, and
the real problem and source of mental instability is blocked
out or only partly experienced and, hence, not addressed (9).
Once present, a symptom may be consciously used to achieve
optimal interpersonal benefits. This is known as the secondary
gain (10). Secondary gain is an ubiquitous interpersonal strat-
egy sanctioned by society if the underlying problem is seem-
ingly genuine or if the interpersonal advantages accrue via
sophisticated or adaptive behaviour. By contrast, hostility and
rejection are the usual responses when interpersonal advan-
tages are extracted from seemingly fake problems, such as
sickness without disease, or when interpersonal strategies are
primitive and transparently manipulative and maladaptive.
Such strategies include unsophisticated interpersonal coer-
cion, avoidance of responsibility, avoidance of noxious con-
sequences, undeserved compensation, and financial reward
without labour. Negative physician response to secondary
gain is unavoidably the result of a value judgement and
applies regardless of whether behaviours have arisen from
organic or from psychiatric conditions. In somatoform disor-
ders, physician hostility is magnified when secondary gain is
felt to derive from signs and symptoms without any under-
lying disease.
In somatization, the fundamental disturbance is a psychiatric
illness that threatens mental stability. The threat to mental
integrity produces anxiety that mobilizes the somatic defences
(11). These defences are responsible for nonorganic physical
symptoms or convert psychic pain into physical pain. This ini-
tial process constitutes the primary psychological gain. Such
patients, like anyone else, use the emergent symptoms for
interpersonal advantage to make the most of their predica-
ment. This constitutes the secondary psychological gain.
Primary gain occurs unconsciously. As a result, the emergent
somatic symptoms are experienced as an unwanted and unin-
vited disturbance. Patients believe and feel that they are sick.
Somatizing patients are not aware of their underlying psychi-
atric disturbance—the motivation that drives the symptoms.
These patients are also not aware that they are deliberating
faking symptoms. However, the specific form of illness that
surfaces reflects the patient’s conscious beliefs about how dis-
ease should present. Symptoms and signs that derive from
beliefs are known as ideogenic (12). Since they reflect a
patient’s concept of sickness, rather than organically dis-
turbed anatomy or physiology, they appear atypical or bizarre
to the examining physician. They either occur in the absence
of identifiable disease or the pattern, severity, and duration of
symptoms and signs, as well as the induced dysfunction, do
not match any known disease. Symptom formation in
somatization is best studied in conversion disorder, where the

symptoms are externalized as an observable neurologic defi-
cit. This deficit can be reversed, revealing in the process the
operative psychological mechanisms (12).
Malingering and Factitious Disorders
An identical cross-sectional presentation is found in 2 other
confounding conditions and is partly responsible for the hos-
tile reception given to somatizing patients. In malingering, the
patient consciously decides to fake illness. The underlying
motivation is also conscious and deliberate and is either to
avoid noxious consequences or to gain undeserved benefits
(13,14). Patients who malinger know that they are pretending
to be ill. Malingered signs and symptoms are ideogenic in that
they reflect the patient’s conscious understanding of how ill-
ness should present. As such, the somatic presentation of
malingering is indistinguishable from that of the somatizing
patient. In factitious disorder, the patient makes a conscious
decision to fake an illness. Unlike malingering, however, the
underlying motivation has never been understood but is
caused by an unidentified, unconscious psychological need.
Nonetheless, factitious patients are fully aware that they are
pretending to be ill, although they cannot clarify either to
themselves or to others the purpose, other than to receive med-
ical attention at any cost, that such a charade serves (14–16)
Since the somatic symptoms are ideogenic, they too are indis-
tinguishable from those of the somatizing patient or the
patient who is malingering (Table 2).
Depression and Symptom Formation in
Somatization and Conversion
The psychiatric disturbance that drives the somatoform disor-
ders is in most cases a major affective illness. Major depres-
sion has been identified in 30% to 60% of patients with
chronic pain and in 48% to 90% of patients who somatize.
Depressive illness has also been found to be present in 54% to
88% of patients presenting with conversion symptoms
(17–23).
There is no agreed-upon explanation about why patients use
somatic defences. Factors that have been associated with
somatization include increasing age, low social class, history
of physical illness, family history of physical illness, member-
ship in cultural groups that discourage emotional expression,
alexithymia (nonpsychological mindedness), and fear of psy-
chiatric stigmatization (24–27).
How or why a patient chooses a specific symptom or sign is
also unclear. Explanations include a symbolic connection to
an underlying conflict or, alternatively, symptom modelling
in which patients mimic somatic symptoms that have previ-
ously occurred in themselves or in a family member as a result
of organic disease (10). Where the symptom is modelled upon
prior organic disease, the term “somatic compliance” has been
used (28). The term “functional overlay” is used when pre-
existing organically determined symptoms and signs are elab-
orated and expanded upon by psychogenic mechanisms,
resulting in nonorganic presentations (29).
Conversion Disorder
Conversion disorder is a specific form of somatization in
which the patient presents with symptoms and signs that are
confined to the voluntary central nervous system (5). When
conversion symptoms occur in isolation, the primary diagno-
sis is conversion disorder. When conversion symptoms occur
as part of a multisystem somatoform syndrome, the primary
diagnosis is somatization disorder (10). “Conversion” or
“conversion reaction” refers to the process whereby
intrapsychic distress is converted into physical neurologic
symptoms (30). Classically, patients present with psycho-
genic seizures or psychogenic motor-sensory deficits. Neuro-
logic presentations may, however, involve any aspect of the
central nervous system over which voluntary control is exer-
cised. Thus, patients may present with a psychogenic demen-
tia as well as loss of speech and language or a disturbance of
any of the special senses (30,31).
The hallmark of a psychogenic neurologic presentation is that
the disruption in voluntary neurologic function does not fol-
low known neurologic damage patterns (30). This reflects the
fact that the neurologic presentation is ideogenic and derives
from patient beliefs about how neurologic symptoms should
present. The emergent symptoms and signs are resilient and
fail to resolve following negative neurodiagnostic investiga-
tions, reassurance, or care-provider rejection and persist
across all settings. Typically, the observed signs—such as
hemiparesis or blindness—are much worse when they are
being formally evaluated or when circumstances bring the
deficits to the patient’s attention. However, whether observed
or unobserved, the neurologic dysfunction remains present
and interferes with the patient’s functioning: the symptoms
are fixed because the beliefs are fixed. Somatic symptoms and
signs attributable to fixed beliefs provide the grounds for con-
sidering that such beliefs represent somatic delusions (12).
The pathophysiology of conversion symptoms thus begins
with a psychiatric illness—most commonly depression—that
threatens to destabilize mental functioning. The somatic
defence, the conviction that “I am physically ill,” forms
unconsciously and surfaces as a fixed belief about the pres-
ence of a specific neurologic malfunction. The patient applies
this belief consciously to govern behaviour, resulting in
bizarre, atypical, and nonorganic findings on neurologic
examination. The role of active inhibition has recently been
demonstrated in some, but not all, functional-imaging studies
(32–36). In a landmark positron emission tomographic blood
flow study of chronic and total left-leg psychogenic paralysis,
174 � Can J Psychiatry, Vol 49, No 3, March 2004
The Canadian Journal of Psychiatry—In Review
attempts by the patient to move the paralyzed leg failed to acti-
vate the right primary motor cortex (32). Instead, the right
orbitofrontal and right anterior cingulate cortex were acti-
vated. These activated areas were deemed to be responsible
for the inhibition of the right premotor and primary
sensorimotor cortex and the resultant left leg weakness. This
active inhibition only became manifest when the patient was
consciously trying to move the paralyzed leg. At rest, there
was no significant asymmetry of activity in the motor cortices.
A similar pattern of simultaneous activation of right frontal
inhibitory areas and inhibition of right somatosensory cortex
was found in case of left-sided paralysis and paresthesias
studied by single-photon emission computed tomography
(SPECT) during electrical stimulation of the left median nerve
(33). Following neurologic recovery, the perfusion patterns
normalized appropriately. In a functional magnetic resonance
imaging study of psychogenic sensory loss, painful and tactile
stimulation deactivated or failed to activate expected primary
and secondary somatosensory cortices and associated cortical
and subcortical networks. Simultaneously, and similar to the
Marshall and others study (32), the anterior (rostral and
perigenual) cingulate cortex was activated, but only during
sensory stimulation that was not subjectively perceived.
Among other observations, the study findings suggested
abnormal cognitive or attentional processing during unper-
ceived stimuli (34). In a SPECT study of acute unilateral psy-
chogenic motor-sensory loss, bilaterally applied passive
vibration led to hypoactivation of thalamus, caudate, and
putamen contralateral to the deficit, which resolved with
neurologic recovery. This study did not show any regions of
significant asymmetric cortical activity (35).
These functional imaging studies provide a growing body of
data supporting the role of conscious active inhibition in the
genesis of psychogenic deficits. Symptom formation that
depends upon conscious active inhibition explains why psy-
chogenic neurologic deficits are less severe when patients are
distracted and more severe when patients attend to their prob-
lem (12). The findings on neurologic examination are also
consistent with cortical and subcortical inhibition controlled
and shaped by higher-order brain centres. For example,
neurologic deficits that are caused by a disturbance originat-
ing in the cortex itself should produce a typical damage pat-
tern, such as the pyramidal distribution of weakness occurring
in a patient who presents with paralysis (30). The physical
findings, however, do not follow these known organic pat-
terns. Instead, physiologically and anatomically naive beliefs
applied consciously and mediated via higher-order brain cen-
tres inhibit downstream cortical and subcortical areas in such
a way that the nonorganic neurologic pattern results. Last, the
role of beliefs in consciously shaping symptoms and signs
provides a coherent and consistent explanation for
psychogenic neurologic presentations that involve positive
neurologic phenomena such as psychogenic seizures and psy-
chogenic movement disorders (37). On neurologic examina-
tion, these are also recognizable as psychogenic because they,
too, fail to follow known organic damage patterns.
Like other somatoform disorders, conversion disorder can be
a treacherous condition: in the past, up to 30% of patients
diagnosed with conversion symptoms were subsequently dis-
covered to have misdiagnosed organic illness (10). In contem-
porary medical practice, with the availability of sophisticated
neuroimaging techniques such as magnetic resonance imag-
ing, missed organic illness may account for 4% to 15% of indi-
viduals initially given a diagnosis of conversion disorder
(38–43). To avoid this error, all patients must be thoroughly
medically investigated.
Management of Conversion Disorder
Patients referred for the treatment of conversion disorder must
first be medically cleared for any neurologic condition. All
such individuals should have undergone appropriate
neurodiagnostic investigations, including prolonged video-
electroencephalographic monitoring in the event of a seizure
presentation.
Conversion symptoms, especially when seen acutely, may
resolve spontaneously with explanation and suggestion. In
some patients, psychogenic sensorimotor deficits may
respond to treatment in a rehabilitation unit using a behav-
ioural approach with no other psychiatric intervention
(44,45). In this group of patients, the primary psychiatric dis-
turbance has seemingly settled. They are left with neurologic
deficits from which they need a face-saving exit. Active reha-
bilitation provides such a vehicle.
Outpatient treatment of patients with conversion symptoms
can be attempted using some of the strategies used in the inpa-
tient setting. Patients with chronic and entrenched conversion
symptoms usually require admission to an inpatient psychiat-
ric unit that has experience with conversion disorders. They
may undergo acute psychiatric decompensation as their
neurologic symptoms resolve. This decompensation reflects
the deconstruction of the somatic defence by treatment that
unmasks the underlying psychopathology, usually depres-
sion. The unmasked psychopathology typically emerges over
weeks, varies from mild to florid, and may include previously
hidden psychosis (23,46).
Patients with sensorimotor disturbances are told that their
neurologic deficits result from a loss of conscious control over
the affected function caused by an underlying neurochemical
disorder, usually, depression. This explanation provides the
cognitive framework for treatment. It is accompanied by
physiotherapy, which may be all that is needed for neurologic

recovery, provided that the patient’s underlying psychiatric
disorder has been identified and accepted and appropriate
treatment started. In patients with entrenched conversion
symptoms, narcoanalysis and narcosuggestion are required to
initiate neurologic recovery. Methylphenidate 5 to 15 mg (a
1-time dose prior to starting each narcoanalysis) is adminis-
tered orally. Thirty minutes later, amobarbital is administered
intravenously at a rate of 50 mg/minute until the patient devel-
ops nystagmus and (or) dysarthria (46). The patient is encour-
aged to regain voluntary control through visual imagery and
suggestion. Narcoanalysis is videotaped and reviewed the
next day with the patient. Videorecorded neurologic recovery,
no matter how small, cogently confirms that the deficits have a
psychological basis. Narcoanalysis is repeated weekly over
several weeks, provided that there are additional neurologic
gains with each procedure. At least 2 narcoanalyses should be
done, as the first narcoanalysis may not yield any neurologic
gains. Recovery of neurologic function is usually slow and
takes place over days, weeks, and months; it is rarely abrupt.
Any recovered neurologic function is reinforced with physio-
therapy and appropriate physical aids provided by a physical
therapist familiar with psychogenic neurologic deficits (47).
Narcoanalysis is also helpful, but not essential, in uncovering
the underlying primary psychiatric disorder. During the initial
narcoanalysis, which may last up to 2 hours, a formal review
of the patient’s history and mental status is undertaken. Areas
covered include a detailed review of the circumstances and
psychological disturbances present at the onset of the conver-
sion symptoms; a review of any relevant psychosocial stress-
ors and conflicts; and the identification of psychopathology,
including any source of symptom modelling and any second-
ary gain.
Exploring the patient’s mental status, with or without
narcoanalysis, is an ongoing process throughout treatment; it
aims to identify and confirm the underlying primary psychiat-
ric disorder. This may be immediately recognizable. More
often, the underlying psychiatric disorder emerges over
weeks, but it may surface precipitously. Relevant dynamics
and psychosocial stressors are also sought and explored. A
histrionic personality disorder is not a prerequisite for conver-
sion disorder (10). La belle indifference is not diagnostically
helpful, as it may be seen in organic conditions (48). Last, dis-
turbed sexuality has no specific connection with conversion
symptoms, although historically it has been identified as one
of the primary conflicts associated with this condition (10).
In patients whose conversion symptoms have been present for
fewer than 6 months, the underlying psychiatric disorder
(most commonly, depression) is often readily discovered
(21). With chronic conversion symptoms lasting more than
6 months, the underlying psychiatric disorder is often not eas-
ily identified. In these patients, the psychopathology may
have been identifiable at the onset of their illness (21).
However, months or years later, when some of these patients
are finally recognized and accept treatment, their overt, acute,
precipitating psychiatric disturbance has become submerged
and entwined with their physical symptoms. The retained
physical symptoms now provide a tenaciously held explana-
tion for their pain, distress, despair, insomnia, lack of energy,
and functional failure.
An essential part of treatment is the establishment of a thera-
peutic alliance that allows patients to recover with dignity and
without loss of face. Staff need to be prevented from respond-
ing to these patients in nontherapeutic ways, such as rejecting
them or becoming angry because of their “unnecessary” phys-
ical dependence and nursing needs or suggesting, subtly or
overtly, that they are attention-seeking, manipulative, and
exaggerating or faking their neurologic difficulties. Patients
need to be helped to recognize their psychopathology and
accept that their symptoms arise from a psychiatric rather than
a neurologic condition. Patients must also be helped to accept
orthodox psychiatric treatments. At every stage, vigilance
needs to be maintained for new symptoms. Any emergent
symptom needs to be adequately evaluated and not dismissed
as another conversion reaction.
Psychogenic seizures require a different approach. Patients are
told that they are having spells, not seizures, and that these
spells are caused by a neurochemical, not an electrical, mal-
function of the brain. Medical attention is then gradually shifted
away from the spells. Anticonvulsants should never be abruptly
abandoned but should be tapered slowly. Provided that the
underlying psychiatric illness is addressed by treatment, the
spells will resolve over time, which can be weeks or months.
Helpful psychotherapeutic strategies include cognitive-
behavioural and expressive–supportive therapy. An
overdetailed history, in which physical symptoms are
reviewed on each and every occasion and in minute detail,
often helps. This task can be demanding for physicians, but it
reassures patients that their physical symptoms are not being
dismissed or overlooked. A rational cognitive framework for
understanding their symptoms helps patients. This is achieved
by providing a tangible mechanism and nonblaming explana-
tion to account for their neurologic symptoms (49). Patients
are told that current evidence indicates that conversion disor-
der is caused by a neurochemical disorder of the brain, most
commonly, depression. This neurochemical disturbance does
not manifest through typical psychiatric symptoms but,
rather, surfaces via unconscious mechanisms as physical
symptoms. Typical psychological hurdles to be overcome
include patients’ reluctance to accept the idea that psychiatric
disorder can cause the obvious and more acceptable somatic
symptoms and their reluctance to accept orthodox psychiatric

therapies, even though they have usually tried many comple-
mentary therapies.
Family therapy is almost always necessary. Families have
often invested heavily in patients’ symptoms and devoted
considerable time and resources to helping patients deal with
their neurologic disabilities. The family will therefore also
have to come to terms with the fact that the neurologic disabil-
ity has been caused by a psychiatric illness. Helping families
accept this condition as a genuine sickness, but one that is psy-
chiatric rather than neurologic, ensures that they continue to
support patients through the period of recovery and beyond.
Pharmacotherapy involves energetic psychotropic medica-
tion trials. Narcotic analgesics taken to control the nonorganic
pain that may accompany psychogenic neurologic deficits
need to be withdrawn. In this setting, they are presumably an
attempt to self-treat the dysphoria of the underlying psychiat-
ric disorder.
Patients with conversion disorder commonly demonstrate
physiological and psychological medication hypersensitivity
characterized by unusual side effects, in part linked to their
reluctance to accept that they have a psychiatric disorder.
They will prematurely abandon medication trials if not given
adequate reassurance and support. Medications may therefore
need to be started at low dosages and gradually titrated
upwards. Here, the goal is to give antidepressants in appropri-
ate dosages and for an adequate duration, similar to the dosing
regimen of any mood disorder. Standard antidepressant medi-
cations are used and include the selective serotonin reuptake
inhibitors, tricyclic antidepressants, and novel antidepres-
sants such as venlafaxine and bupropion. Neurologic symp-
toms that fail to resolve with antidepressants alone should be
treated with neuroleptics. Neuroleptics target somatic delu-
sions (one hypothesis for the resistance of somatic symptoms
in the face of incontrovertible evidence that no organic dis-
ease is present). Atypical neuroleptics are preferable because
they carry a lower risk of tardive dyskinesia. If this strategy
fails, patients should be offered a course of electroconvulsive
therapy, which may succeed in recovering neurologic func-
tion and effectively treat the underlying psychiatric disorder
(46).
Prognosis Few studies describe the prognosis for psychogenic deficits and
their associated primary psychiatric disorder. A shorter dura-
tion of psychogenic neurologic deficits is associated with a
better neurologic prognosis (39–41). Even without specific
treatment directed at recovering neurologic function, 28% to
63% of patients will have a complete remission of their present-
ing neurologic symptoms; 20% to 29% will show some
improvement; and 10% to 52% will be unchanged or worse
(38–42). In our unit, with treatment algorithm as described,
68% of patients demonstrated a full neurologic recovery, 12%
had a variable recovery, and 20% failed to demonstrate any
recovery (T Hurwitz and B Kosaka, unpublished observations).
These 20% were felt to have a severe and treatment-resistant
underlying psychiatric disorder. In a subgroup of these
treatment-resistant patients, the acute precipitating psychiatric
illness has seemingly fully resolved, but the neurologic symp-
toms persist, retained as a maladaptive behavioural pattern and
perpetuated by the advantages of the sick role, wherein life as
an invalid is preferable to all other options. Slater has described
this group as “invalids of choice” (50).
Recovery of neurologic function does not, however, end the
patients’ difficulties. In a 6-year follow-up, 36% of patients
had persistent, active, psychiatric problems; only one-third of
patients were working full-time; and 47% were retired on the
grounds of ill-health. At follow-up, the identified psychiatric
disorder was mostly either a continuation or a relapse of the
psychiatric disorder identified at the initial presentation (39).
In another follow-up study of patients with conversion disor-
der, 34% were suffering an episode of major depression at
follow-up. The mean number of years from the index clinical
contact to the follow-up interview was 4.2 (42). These studies
indicate the importance of identifying and treating the under-
lying psychiatric disorder.
Conclusion
Conversion disorder is a challenging psychiatric disorder that
requires long-term commitment on the psychiatrist’s part and
uses the full spectrum of psychiatric skills. Conversion reac-
tions represent a somatic defence against threats to mental sta-
bility that are most commonly attributable to an underlying
mood disorder. Perseverance through the diagnostic and treat-
ment phases is more often than not rewarded by positive
results. Patients require long-term care to manage their mood
disorders and associated psychosocial issues. One important
role of the treating psychiatrist is to ensure that any new physi-
cal symptom receives appropriate medical investigation from
the rest of the medical profession. Physicians are usually baf-
fled and annoyed by patients with conversion disorders and
remain too quick to dismiss any new somatic symptom as
“more of the same,” to the patients’ great detriment.

Résumé : Somatisation et trouble de conversion
La somatisation est le mécanisme psychologique par lequel la détresse psychologique
s’exprime sous forme de symptômes physiques. La détresse psychologique de la
somatisation est le plus souvent causée par un trouble de l’humeur qui menace la stabilité
mentale. Le trouble de conversion survient lorsque la présentation somatique touche un
aspect quelconque du système nerveux central sur lequel s’exerce un contrôle volontaire. Les
réactions de conversion représentent des idées fixes sur la dysfonction neurologique qui sont
consciemment adoptées, ce qui résulte en des déficiences neurologiques psychogènes. Le
traitement est complexe et long; il comprend le rétablissement de la fonction neurologique à
l’aide de la narcoanalyse, de l’identification et du traitement du principal trouble
psychiatrique, habituellement un trouble de l’humeur.
