Is electroconvulsive therapy unsuitable for
children and adolescents?
Baldwin, Steve; Jones, Yvonne
Vol. 33, Adolescence, 09-22-1998, pp 645(1).
Few treatment approaches have caused as much
controversy as electroconvulsive therapy (ECT).
Since its first documented use in the 1940s
(Cerletti, 1956; Slater, 1951), there has been
ongoing discourse about its effectiveness. This
debate has generated much heat but insufficient
light to permit conclusive recommendations about
the limits of its application.
In the 1950s, ECT was viewed by many physicians as
harm-free and potentially useful for a wide range
of disorders and client populations. It was
considered helpful in the treatment of affective
disorders, in particular chronic depression -
"cases in which the clear-cut, dynamically
understandable and approachable neurosis has been
overlaid by a serious depressive affect"
(Gallinek, 1952). In the treatment of neurotic
disorders, ECT was viewed by some psychiatrists as
of decisive benefit; it often marked a turning
point from therapeutic failure to perceived
therapeutic success. Other clinical problems, such
as anorexia nervosa, were also considered
potentially resolvable by ECT. Similarly, client
populations with schizo-affective disorders,
narcotic addiction, and obsessive-compulsive
behavior were included in many early clinical
trials. The literature on ECT with minors was
sparse, although some children and young adults
were included in treatment populations (e.g.,
Gallinek, 1952).
ECT research and practice during the 1960s was
characterized by efforts to understand how it
produced results, with further attempts to specify
optimum client populations (Abrams & Fink, 1969;
Mendels, 1967; Sargent & Slater, 1963). Although
there was more interest in the establishment of
experimental designs to evaluate the effectiveness
of ECT, many of these were unsophisticated trials
with poor methodologies, producing inconclusive
results. Most studies were based on ad hoc
variations of normal clinical practice.
In the 1970s, increasing concern in the mental
health field about client rights prompted a series
of surveys and studies about ECT and its
applications. This closer examination of ECT was
associated with a narrowing of clinical focus to
specific disorders with more discrete populations.
The seminal task force report on ECT in
Massachusetts influenced a generation of
clinicians. It found that "most authoritative
publications appear to be in agreement that
symptoms associated with the depressed phase of
manic-depressive illness or involutional
melancholia are treated most effectively by ECT"
(Frankel, 1973). Nonetheless, the report noted
continuing disagreement in the field with regard
to the use of ECT with adults who had
schizophrenia, its combined use with psychotropic
drugs, and questions about subsequent brain
damage. The use of ECT in childhood and adolescent
disorders similarly was viewed as an area of
unresolved debate.
An analysis of responses to the task force
questionnaire (from which the report was written)
indicated that all respondents assigned some value
to ECT in the treatment of severe depression,
especially when risk for suicide was present. Some
practitioners stated that it would be appropriate
to consider ECT when psychotherapy or use of
medication had been unsuccessful, or when a poor
response to other therapies had rendered the
person nonfunctional. Most respondents indicated
the need to complete extensive pretreatment
examinations (typically including an ECG, a chest
x-ray, an EEG, a spine x-ray, a brain scan, and
additional neurological tests) to determine the
suitability of ECT for individual clients. About a
third of the respondents (17 of 56) emphasized the
inadvisability of ECT with children or
adolescents, or to persons with neurotic/addictive
behavior problems. Other contraindications were
noted, and:
for patients who are angrily dismayed or
frustrated by disappointing events in their lives
but who are still able to function adequately in
other spheres, in whom there is no evidence of
recognizable psychosis or serious suicidal thought
or action, skilled psychotherapy should be
energetically and adequately administered, with or
without the assistance of medication. ECT is not
the treatment of choice in such conditions, as it
can neither remove nor resolve life-situational
problems (Frankel, 1973).
With regard to adverse effects of ECT, the task
force report focused on memory loss. Although no
respondents offered incontrovertible proof of
deterioration, nearly 18% (10 of 56) indicated
irrecoverable gaps in memory, intellectual
deterioration, or blunting in individual clients
after multiple administrations. In contrast, other
practitioners claimed never to have seen adverse
effects, despite extensive use of ECT.
Concerning legal and ethical considerations, there
was widespread agreement about the need for
informed consent prior to ECT. A "treatment
request," describing the procedure and stating
that all questions had been answered, should be
read and signed. If the person was unable to grant
consent, the consent of a relative or guardian
should be obtained; commitment laws could also
provide the legal machinery for an in lieu
agreement.
The task force was unanimous regarding the
treatment of young persons: "administration of ECT
to children who have not yet reached puberty has
no established usefulness and that therefore such
treatment on a routine basis cannot be justified"
(Frankel, 1973). However, if ECT was offered as a
treatment procedure for prepubertal children, then
(1) it must be explained to parents/guardians that
effectiveness of ECT for psychiatric disorders in
preadolescent children is not proven, and that
such use is not generally accepted; (2) that
following a rigorous investigation of the case,
explicit indications for an experimental trial
should be recorded, and that the quality of the
study should ensure publishable results; and that
(3) it would be prudent before proceeding to have
concurrence by a colleague from another hospital,
providing additional clinical justification for
the experimental use of ECT with a particular
child. The problems posed by diagnosis and
treatment of persons aged 13 to 16 prompted
unanimity that consultation with a colleague be
encouraged when ECT is contemplated. Many
respondents were in favor of recommending
mandatory consultation with a colleague in another
hospital before administration of ECT to young
clients.
The report also recommended conducting unbiased
follow-up studies to evaluate the effectiveness of
ECT. In addition, all persons who administer it
should familiarize themselves with other treatment
methods, allowing long-term comparative studies.
The report concluded: "we believe that the onus is
now on those whose views differ markedly from the
recommendations expressed here to report their
findings" (Frankel, 1973).
In the United Kingdom, ECT with children and
adolescents generally was viewed during the 1970s
as an unusual but not exceptional treatment. It
was available as a treatment option to "control an
acute psychotic or depressive illness," and was
considered "if all drug treatments have failed
after proper and prolonged use to control the
illness" (Frommer, 1972). In some psychiatric
clinics, it was viewed as an option for
adolescents who were persistently suicidal and was
made available as an inpatient treatment, prior to
outpatient administration. As in treatment with
adult populations, ECT was continued as long as
the client showed improvement. Some physicians
recommended that ECT should not be withheld on the
basis of age alone, but rather should be a
pragmatic treatment decision following nonresponse
to pharmacotherapy (Frommer, 1972).
This scenario was complicated, however, by
controversy over the diagnosis (and treatment) of
affective disorders (i.e., depressive or manic
behavior) in children. Indeed, the very existence
of some depressive disorders in this population
was questioned (Warneke, 1974). Disagreement about
nosology and diagnosis even extended to the
definition of the term "children"; some clinicians
had recommended that this category be reserved for
young persons who had not developed secondary
sexual characteristics (Anthony & Scott, 1960).
Diagnostic criteria for manic-depressive disorders
often were based on circular definitions (e.g.,
"evidence of abnormal psychiatric state" or
"positive family history"), which sometimes veered
toward tautology (e.g., "evidence of severe
illness as indicated by a need for inpatient
treatment, heavy sedation, and ECT") (Warneke,
1974). based on a physical pathological model, the
presence of an endogenous condition was clinically
determined by the nonappearance of other
environmental indicators. The supposed existence
of illness/disease states thus often hinged on the
absence, not presence, of clinical data.
Even by the mid-1970s, the literature on ECT with
minors was still minimal. Many standard texts on
child psychiatry omitted any reference to the
applications of ECT with children or adolescents.
Other psychiatric texts included brief references
to possible clinical indications for its
administration, such as "when a severe and
handicapping affective disorder fails to respond
to an adequate dose of antidepressants together
with appropriate psychotherapeutic measures and
environmental modification" (Rutter & Hersov,
1976). Such recommendations included the proviso
that ECT should be used only if the affective
disorder showed the characteristics associated in
adults with a good response; failure to respond to
other treatments was not considered to be a
sufficient indication on its own.
Toward the end of the 1970s, other reports
confirmed the narrowing of focus to specific
clinical populations and disorders. A survey of
New York hospitals in 1975/76 indicated primary
use by physicians for endogenous depression, and
secondary use with clients who had previously
failed to respond to psychotropic drugs (Asnis,
Fink, & Saferstein, 1978). All reported occasional
use with adolescents; one physician (from a sample
of 30) reported use of ECT with children under the
age of 13. For all 30, a medical history, a
physical examination, a chest x-ray, an ECG, and
blood and urine tests were required prior to
treatment. Written consent was obtained for all
voluntary clients; procedures were different for
people who refused consent. Sixty percent (18 of
30) of the physicians had written guidelines for
the administration of ECT.
The training and experience of psychiatric staff
influenced the choice of treatment (Asnis, Fink, &
Saferstein, 1978). Where nonmedical mental health
workers held responsible clinical or
administrative positions, a lack of sympathy or
experience with medical aspects of psychiatric
problems may have biased treatment choices toward
social, rather than medical, approaches.
Alternatively, ECT may have been reserved for
people who had failed to respond to other
therapies. The study noted variations in consent
procedures, infrequent modification of ECT,
minimal record-keeping, and paucity of training
courses for ECT administration; it was concluded
that improved monitoring of the ECT process was
necessary.
In Britain, a contemporaneous review of ECT
suggested there were "plenty of testimonies to the
value of ECT in all manner of psychological and
behavioural troubles, but a dearth of scientific
inquiries into efficacy" ("ECT forty years on,"
1979). The review noted that the biological
mechanism of action was still unclear, and that
more information had been obtained about how ECT
did not work.
There was also a powerful civil rights lobby
emerging that was concerned with the safety of ECT
and its possible side effects. In particular, a
popular view among mental health reformers was
that ECT was experimental, hazardous, and
irreversible; it should never be used with
compulsorily detained persons without the consent
of an independent, multidisciplinary review body
(Gostin, 1975).
The topic of consent (and competency to give it)
came to the forefront. In the most celebrated
ruling, an Alabama state judge ruled that before
ECT could be administered (even when consent had
been obtained), confirmation from four
psychiatrists and one neurologist, as well as
monitoring by two attorneys, was required. By the
end of the 1970s, the prevailing ethos in the
United Kingdom was to seek a second, independent
psychiatric opinion whenever ECT was considered
for compulsorily detained persons, with a
multidisciplinary review panel to reach a decision
in these circumstances (Clare, 1978).
At the beginning of the 1980s, several reviews of
the clinical use of ECT suggested a shift toward
greater consensus about use (and nonuse) with
specific disorders and client populations. It was
advocated mainly as an effective treatment for
adults with severe mood disorder, and also for
people with sleep disturbance, loss of
appetite/weight, retardation, morbid guilt, and
some delusional states. No evidence was presented
for the use of ECT with chronic schizophrenia,
psychoneurotic or obsessive- compulsive
conditions, delirium tremens, or narcotic
withdrawal. Risks were identified (e.g.,
mortality/morbidity via cardiac arrest from vagal
inhibition, coronary thrombosis, cerebral
hemorrhage, and pulmonary thrombosis). No absolute
contraindications for ECT were reported, however
(McKenna & Pratt, 1983). The proven existence of
amnesia/memory loss after ECT was considered by
practitioners to be offset by its advantages.
It was noted that, as part of "valid consent," a
full explanation of ECT should be given to the
client, including information about risks,
benefits, and side effects. The consent form
should state that this information had been
provided, and be signed by both the psychiatrist
and the client. Moreover, although valid consent
should precede ECT treatment, it could be
withdrawn at any stage. Also, it was affirmed that
next of kin or other close relatives were not
allowed to give consent should the client refuse
ECT; relatives had no legal right to give consent
on behalf of another person.
The following were considered essential for
practitioners in the United Kingdom if the client
was unwilling to accept or did not understand ECT
after it was recommended: (1) consider whether
there are grounds for compulsory treatment; if
not, ECT cannot be given; (2) obtain the opinion
of two other consultants to advise about the
necessity of compulsory ECT; (3) invoke Section 26
of the Mental Health Act (Section 24 in Scotland);
(4) obtain written consent of nearest relative;
(5) record that relative's objections if he or she
disagrees with treatment (and reasons for deciding
to proceed); and (6) consult with other staff
involved in the client's treatment. Although
children and adolescents were not specifically
included in this category, young persons were
considered unable to understand fully what was
asked of them.
In another review from the United Kingdom (Pippard
& Ellam, 1981), analysis of a survey of 2,755
[Image]psychiatrists suggested that 1% were opposed to
the use of ECT; 87% regarded ECT as at least
"occasionally useful" with adult clients with some
problems. Such problems included depressive
psychosis, melancholia, and endogenous depression.
In child psychiatry, the use of ECT was "even more
restricted; it was rarely used and mostly, if not
only, in post-pubertal children with adult- type
psychotic illness. . . . A minority opposed its
use in children under any circumstances" (Pippard
& Ellam, 1981).
The survey indicated that the physician usually
explained ECT to both the client and relatives.
Nurses were often (and social workers rarely)
involved with this process. No written explanation
of ECT was given in 87% of the cases. For those
people unable to give valid consent, the decision
was viewed as the responsibility of the
psychiatrist. While multidisciplinary staff were
viewed as acceptable for consultation, final
decision-making remained with the physician. Wide
variation in recording the process of ECT was
noted; some clinics used special forms to record
details, while others kept only case notes. The
survey produced many recommendations to improve
administration of ECT in clinics, through either
procedural reforms or revision of codes of
practice.
Another review of the status of ECT in psychiatric
practice confirmed many of these findings, in
particular that ECT could be an effective
treatment for severe depression in adult
populations (Kendall, 1981). Benefits of ECT for
chronic schizophrenia and mania were less clear,
with a range of evidence to support both use and
nonuse with such psychiatric problems. Some
evidence was presented for impairment of memory
(or new learning) after ECT administration,
although its extent or severity in adults remained
unknown.
Kendall (1981) noted an overall reduction in the
use of ECT among clinical populations after
legislative restrictions and adverse publicity.
The range of clients, problems, and settings at
the beginning of the 1980s became more limited,
often restricted to adults with severe endogenous
depression. However, situations where it was
necessary to alter or prevent problem behaviors as
quickly as possible, such as refusal to eat or
drink or suicide risk, were deemed appropriate for
ECT. Despite occasional reports of its use in the
treatment of anorexia nervosa, obsessional
illness, organic confusional states, psychogenic
pain, and other conditions (unless there was
evidence for depression), "such use has neither
theoretical justification nor empirical support
and is therefore inappropriate" (Kendall, 1981).
Findings regarding consent indicated that some
people who had been given ECT claimed never to
have received an adequate explanation of what the
treatment involved (e.g., Freeman & Kendell, 1980;
Hughes et al., 1981). Kendall (1981) concluded
that ECT would eventually be supplanted by some
kind of pharmacotherapy.
A more recent review noted the comparative rarity
of the use of ECT with children (Black, Wilcox, &
Stuart, 1985). Although ECT has been used with
adolescents (e.g., for affective disorders,
schizophrenia, and eating disorders), it has
seldom been used to treat disorders occurring
before puberty.
STUDIES OF ECT WITH MINORS
Research on the use of ECT with children and
adolescents consists mainly of single-case reports
and uncontrolled studies (Baldwin & Oxlad, 1996).
Although some older texts have identified ECT as
an option in the treatment of childhood
schizophrenia (e.g., Freedman et al., 1972;
Redlich & Freedman, 1966), others have been less
positive (Kanner, 1966). Some clinicians have been
enthusiastic (Bender, 1947, 1973); other
investigators have been less sanguine and have
declared the use of ECT with children exhibiting
psychotic behavior of scant value (Clardy, 1951;
Hift et al., 1960).
Few clinicians have been directly involved in
either the administration or evaluation of ECT
with children and adolescents (El-Sharif, 1993).
Although practitioners often employ psychological
interventions with a physical component (e.g.,
behavior modification), many view ECT with minors
as outside their professional province.
The literature on ECT with children and
adolescents offers no controlled studies, no
reliably applied criteria, and no valid assessment
scales (Black, Wilcox, & Stuart, 1985). Also, use
of ECT with children has been relatively
unpopular. Because endogenous depression is rare
in prepubertal children, practitioners should not
need to consider the use of ECT. In short, the
literature indicates that ECT has an unknown
mechanism of action, with a domain of
applicability diminished yearly by legislation,
litigation, and a wide range of intervention
alternatives.
CLINICAL DILEMMAS
It is not unusual for psychological interventions
to receive both praise and criticism; "time out,"
for example, has avid supporters and fierce
opponents. Drug treatments, such as lithium
therapy, have been the subject of vitriolic
attacks. Pharmacological treatment of hyperkinetic
behavior among children and adolescents in the
1980s subsequently faced a strong backlash.
In the 1990s, increased malpractice litigation
against physicians has influenced treatment
approaches (Monrad Aas, 1991). In the United
Kingdom, where ECT has been given to minors
against their wishes, criminal assault charges
have been filed in some cases (Baldwin & Jones,
1990, 1991; Jones & Baldwin, 1992). There has been
more litigation in the United States, although
increased activity by advocacy organizations and
consumer groups has irreversibly altered the legal
climate in the United Kingdom.
The contemporary interdisciplinary team approach
to psychiatric care has promoted the use of a
range of effective, tested intervention
alternatives. However, interprofessional contact
has increased the probability of disagreement
about optimum treatment. One source or
professional conflict that has emerged during the
1990s has not yet been satisfactorily resolved.
Different professional codes require
psychiatrists, psychologists, and nurses to react
differently to the administration of ECT with
children and adolescents (Oxlad & Baldwin, 1995).
Problems generally have occurred when there was
doubt about the capacity of the young person to
give valid consent.
In the United Kingdom, the professional
obligations of clinical psychologists are clear,
according to the British Psychological Society' s
(1987) code of conduct. Clinical psychologists
should:
recognise and uphold the rights of those whose
capacity to give valid consent to interventions
may be diminished, including the young, the
mentally handicapped or the elderly, those in care
of an institution or detained under the provisions
of the law,
and:
where interventions are offered to those in no
position to give valid consent, after consulting
with experienced professional colleagues,
establish who has legal authority to give consent
and seek consent from that person or those
persons.
Similarly,
in exceptional circumstances where there is
sufficient evidence to raise serious concern about
the safety or interests of recipients of
services... take such steps as are judged
necessary to inform appropriate third parties
without prior consent.
Thus, in a context where some applications of ECT
with minors have previously led to charges of
negligence, professional misconduct, or criminal
assault, practitioners should be aware of their
professional obligations. If this results in
conflict among professionals, third- party
nonmedical intermediaries may need to become
involved.
