PREFACE
|
|
When it comes to the
treatment of OCD, patients will find that unlike
some conditions where only medication seems to be
really effective, there are nonmedication
treatments for OCD that are just as -- or more --
effective than medication. In the remainder of this
article, we will summarize some of the research on
these treatments and talk a bit about what else is
available if the "first line" treatments either do
not work or the individual cannot or does not
comply with the treatment regimen.
We will also consider
the role of the family, because although family
always makes a difference, when it comes to OCD,
well-meaning family members often inadvertently
enable the problematic behavior and
patterns.

MEDICATION MANAGEMENT OVERVIEW
|
|
The class of
medications known as SSRIs (Selective Serotonin
Reuptake Inhibitors) appear to be the first-line
treatments pharmacologically. In the U.S.,
available SSRIs include fluoxetine hydrochloride
(Prozac®), paroxetine hydrochloride
(Paxil®), sertraline hydrochloride
(Zoloft®), fluvoxamine maleate (formerly marketed as Luvox®),
citalopram (Celexa®), and escitalopram oxalate
(Lexapro®). Not all are approved by the FDA for treatment of OCD.
Research on the SSRIs
suggest that they are effective in treating OCD in
adults, children, and adolescents. About 60 - 70% of OCD sufferers benefit from medication treatment. Some patients report feeling some
improvement within days of starting an SSRI, but it
may take 2-3 months before the levels build up in the
system sufficiently to give the individual any
noticeable relief. A meta-analysis of research studies investigating SSRIs in the treatment of OCD found that there were no significant differences among the SSRIs in terms of their effectiveness (Meth & Reddy, 2007). There are conflicting data as to whether any beneficial effects persist after medication is discontinued.
The other 30 - 40% of patients generally do
not respond well to SSRIs or do not achieve
satisfactory results with SSRIs. Patients with OCD
who have poor insight (as to the irrationality of
their obsessions and compulsions) do not respond as
well to SSRIs as those with good insight. The presence of comorbid conditions may also predict a poorer response to medication: children with OCD who have comorbid ADHD, Oppositional Defiant Disorder or Conduct Disorder do not benefit as much from SSRIs (Grados & Riddle, 2008).
Although SSRIs are generally accepted as first line of treatment, they are not the most effective medication for OCD. An older medication that is not serotonergic-selective, clomipramine hydrochloride
(Anafranil®), has been shown to be more effective than the SSRIs and is approved for treatment of OCD in children and adults. Physician reluctance to prescribe it may be due more to its side effect profile: it can produce gastric discomfort, flatulence, weight gain and other problems.
As suggested above,
any benefits of medication may not persist when medication is discontinued. Maina et
al. (2001) investigated the effects of reintroducing an SSRI if a patient relapsed after discontinuing SSRI treatment. They found that patients who were responders during the intial treatment did respond again when SSRIs were re-introduced, but they got less benefit with the re-introduction. Their data have important implications for treatment in terms of whether medications should be discontinued.

MEDICATIONS -
ADVERSE EFFECTS
|
|
The SSRIs do have
side effects that may be problematic in some cases.
Insomnia or somnolence, nausea, diarrhea, sweating
or tremor, activation or hypomania, and delayed
ejaculation or impotence are just some of the
adverse side effects that have been reported in the
literature. Some patients have also reported unpleasant withdrawal-emergent effects associated with
stopping SSRIs. Perhaps the most contentious side effect has been whether SSRIs induce suicidality. In 2004, the FDA required a "black box warning" for the use of SSRIs with youth; the warning went into effect in 2005. In the years since the warning was mandated, prescriptions for SSRIs decreased significantly. Of concern, suicides increased. A discussion of the history of the FDA warning and the data it was based on can be found in an article by Kyle and Cortes in Pharmacy Times.
One other potential
adverse effect is something called "amotivational
syndrome," a frontal lobe syndrome associated with
the use of SSRIs that is characterized by apathy
and lack of motivation. Garland and Baerg (2001)
reported on four children and one adolescent who
experienced this syndrome while on SSRIs; one of
the children also experienced behavioral
disinhibition. The authors note that the symptoms
were dose-related and reversible, but that the lack
of insight in patients and delayed onset indicate
that clinicians need to inform patients and
families of the potential symptoms. A subsequent literature review by Barnhart, Makela, and Latocha (2004) confirmed their findings and recommendations.
As with every prescription medication, patients
taking SSRIs need to be educated about what to watch out for and potentially
dangerous medication combinations, including
combinations with over-the-counter compounds.
If you're not sot
sure what to ask your doctor when medications are
being considered for any of the conditions
discussed on this web site, see my suggestions in
"Questions
to Ask About Medications."
If SSRIs ameliorate symptoms but provide inadequate relief, the physician may recommend switching to clomipramine (mentioned above), or the physician may recommend augmenting the SSRI with either a second medication or cognitive-behavior therapy. To date, only atypical neuroleptics (such as Risperdone®) have been been empirically validated as effective augmenters (Math & Reddy, 2007).
Research demonstrating a relationship between glutamate and OCD [cf, Yücel, Wood, et al., (2008); Starck, Ljunberg, et al., (2008); Sjigart, Wang, et al., (2009)] offer another possibility for treatment or augmentation. Preliminary studies using memantine (Namenda®) and riluzole (Rilutek®) which are glutamate antagonists, and glycine, a glutamate receptor agonist, found that a significant percentage of non-responders to SSRIs or SSRI plus atypical neuroleptic responded well to the treatment [Aboujaoude, Barry, & Gamel,(2009); Greenberg, Benedict, et al., (2008); Grant, Lougee, et al. (2007)].

SURGERY
FOR OCD AND ALTERNATIVE TREATMENTS
|
|
Psychosurgery may also be
an option for some people with severe
treatment-resistant OCD. The topic is too complex
to discuss on a web site of this type, but there
are some data suggesting that in severe OCD that
has not responded to medication and therapy,
certain Anterior cingulotomy and deep brain stimulation may be of benefit.
There is no adequately controlled research indicating that any alternative or complementary treatments such as herbals would be of benefit in treating OCD. Initial reports of Inositol as an effective treatment were not replicated. St. John's Wort (Hypercin/Hypercium) is similar to the SSRIs in that it affects the serotonin system, but the one study investigating its effectiveness in treating OCD found that it did not produce any benefit over and above a placebo (Kobak, Taylor, et al., 2005).
Although no alternative treatments have met scientific standards for demonstrated efficacy, that does not seem to stop many places and professionals from using them or selling them. If you want to explore alternative treatments that have not passed the usual standards for demonstrating efficacy, be an informed consumer: ask questions about success rate, ask how long it will take before effects are noted, ask what the risks are, and ask to see copies of all research reports supporting the use of the herbal or treatment. Then check with your regular physician to see if the physician has any concerns about potential side effects or interactions.

COGNITIVE BEHAVIOR THERAPY OVERVIEW
|
|
One of the most
clinically effective approaches to treating OCD is
a nonmedication approach, Cognitive Behavior
Therapy (CBT). The term "CBT" refers to a broad
class of therapeutic interventions that involve
changing both the individual's cognitions
(thoughts) and behavior. Of particular relevance is
the type of CBT known as Exposure-Response
Prevention therapy (ERP). In ERP, the client and
therapist may construct a hierarchy of situations
that are progressively more difficult in terms of
resisting the need to engage in the targeted
compulsive behavior. The client is taught how to
relax, and then starting with the least intense
item on the hierarchy, the client intentionally
exposes him/herself to the 'trigger' for the
compulsive behavior while resisting the performance
of the behavior itself.
The "exposure" can be
done in the patient's imagination and/or in "real
life." The logic of the technique is fairly
straightforward. In the presence of the 'trigger'
or the obsessive thought, the individual's anxiety
will rise. Prior to therapy, the individual would
engage in the compulsive ritual and thereby reduce
the anxiety. The problem with that, however, is
that the performance of the ritual was actually
reinforced ("rewarded") by reduction in anxiety,
thereby strengthening the likelihood that
the individual will engage in the compulsive
behavior again in the presence of the
anxiety-producing obsessive thought.
In ERP, the trigger
is present and the individual's anxiety is
generated, but now the compulsive behavior is not
performed. What will happen? The first thing that
happens is that anxiety levels will probably rise.
And rise. And rise. If the individual is able to
employ any relaxation or distraction techniques and
is able to successfully stop herself from
performing the ritual/compulsive behavior,
eventually (and "naturally"), the anxiety will
start to subside. This part of the process is known
as "extinction" -- the anxiety response is not
followed by any consequences, and so extinguishes
or dies out. The next time the individual is
exposed to the trigger/stimulus, their anxiety will
rise again, but again, if they don't perform the
compulsive behavior, their anxiety will extinguish.
Over sessions and weeks, the individual's anxiety
will diminish to a point where the trigger/stimulus
no longer produces an anxiety response. At that
point, the therapist and client may go to a more
challenging item from the hierarchy.
Participating in CBT
is hard work. Young children often lack insight
into the irrationality of their obsessive thoughts
and/or may not be motivated to address what the
adults in their lives see as a significant problem.
And even adults who do have insight may find the
anxiety so overwhelming that they are unable to
even get started in such therapy. For those who
have very severe OCD, a combination of medication
and therapy may be indicated, with the medication
serving to bring the OCD symptoms down to a
manageable level so that the individual can benefit
from the therapy, but even that is controversial,
because if you reduce the person's symptoms via
medication, you may also reduce their motivation to
do the cognitive-behavioral work.
Piacentini and his
colleagues at UCLA conducted open trials on CBT
with children with OCD (2002). The 42 children
(approximately half of whom were on medication at
baseline) were given a treatment protocol based on
ERP. For the sample, there was a clinically
significant response to treatment. The
investigators note that for this sample, poorer
outcome was associated with more severe obsessions
and greater OCD-related academic impairment prior
to treatment.
There are many
variations on CBT and the preceding was meant
simply to give you an idea of the kind of approach
that might be used. A number of intriguing research
reports have appeared in the literature, with some
investigators comparing in vivo exposure to the
'trigger' to purely cognitive strategies. Some
studies suggest suggested that cognitive interventions alone or behavior therapy alone may be as effective as cognitive-behavior therapy.
At the present time, both CBT and medication are considered first line treatments for OCD. A stud by
Dr. John March and his colleagues (2004) (pdf) directly investigated whether CBT alone (in this case, Exposure-Response Prevention), SSRI
medication alone, or CBT and SSRI therapy combined
were most effective in treating OCD in children and
adolescents. In their multi-center study,
sertraline was the SSRI used for the SSRI
condition. The SSRI-alone, CBT-alone, and SSRI-CBT
combination were all significantly more effective
than the placebo condition. Additional analyses of
their data indicated that combined treatment and CBT-alone did not differ from each other significantly, but both were significantly better than medication-alone the remission rate outcome. Based on their findings, they recommended that children and teens with
OCD should begin treatment with a combination of
CBT plus an SSRI or just start with CBT
alone. The current practice guideline (pdf) for psychiatrists advises:
|
In choosing a treatment approach, the clinician should
consider the patient’s motivation and ability to comply
with pharmacotherapy and psychotherapy [I]. CBT and
serotonin reuptake inhibitors (SRIs) are recommended as
safe and effective first-line treatments for OCD [I]. Whether
to utilize CBT, an SRI, or combined treatment will depend
on factors that include the nature and severity of the
patient’s symptoms, the nature of any co-occurring psychiatric
and medical conditions and their treatments, the
availability of CBT, and the patient’s past treatment history,
current medications, capacities, and preferences.
CBT alone, consisting of exposure and response prevention,
is recommended as initial treatment for a patient
who is not too depressed, anxious, or severely ill to cooperate
with this treatment modality, or who prefers not to
take medications and is willing to do the work that CBT
requires [II]. An SRI alone is recommended for a patient
who is not able to cooperate with CBT, has previously responded
well to a given drug, or prefers treatment with an SRI alone [II]. Combined treatment should be considered
for patients with an unsatisfactory response to monotherapy
[II], for those with co-occurring psychiatric conditions
for which SRIs are effective [I], and for those who
wish to limit the duration of SRI treatment [II]. In the latter
instance, uncontrolled follow-up studies suggest that
CBT may delay or mitigate relapse when SRI treatment is
discontinued [II]. Combined treatment or treatment with
an SRI alone may also be considered in patients with severe
OCD, since the medication may diminish symptom severity
sufficiently to allow the patient to engage in CBT [II].

The guideline reflects findings that benefits of medication may not continue once medication is stopped, that CBT can reduce the need for medication [cf, Cottraux et al. (1993)], and that incorporating CBT can help prevent regression to pre-treatment symptom levels. The value of cBT is also demonstrated by brain imaging studies that indicate that therapy -- even without medication -- normalizes brain function [cf, Nakatani et al., (2003); Linden (2006); Nabayema et al. (2008); and Saxena et al. (2009)].

ROLE OF THE FAMILY
|
|
Regardless of whether
OCD is inherited or nonfamilial, it impacts the
entire family. Parents or family members are often
at a loss as to whether to accommodate the
relative's symptoms and possibly enable them, or
"hang tough" or take some other course.
Amir et al. (2000)
looked at: (1) the family's reactions to OCD as a
function of the severity of the patient's symptoms
and (2) the effects of family accommodation and
rejection on treatment outcome. Prior to treatment, the family's accommodations and responses affected the family's functioning but were not related to the severity of the child's OCD. Following treatment, family
accommodation was related to the severity of
patients' OCD. From a correlational study of this kind, it is not clear whether the parental accommodations contributed to the severity of the child's symptoms or were merely a reflection of the possibility that the more severe symptoms required more accommodations by the family.
Their findings received partial support in a subsequent study by Peris, Bergman et al. (2008). These investigators found parents commonly made accommodations for their children's OCD. Parental involvement in rituals correlated positively with higher levels of child OCD severity and negatively with levels of family organization.
Getting the family involved in treatment is
obviously an important component in planning any
treatment regimen. Training the family how to
respond to the child or family member, and
interventions oriented towards training family
members to use techniques that foster
problem-solving, independence, and greater
self-confidence may all improve the child's
functioning.
