No evidence of pregnancy, but she is suicidal and depressed after ‘my baby died’

EVALUATION Confrontation
At admission, Ms. R remains resolute that she was pregnant and is suffering immense psychological distress secondary to the death of her child. Early in the treatment course, she is confronted with evidence indicating that her pregnancy was impossible. Shortly after this interaction, nursing staff alerts the treating physician that Ms. R experienced a “seizure-like spell” characterized by gross non-stereotyped jerking of the upper extremities, intact orientation, retention of bowel and bladder function, and coherent speech consistent with a diagnosis of pseudoseizure.²

Ms. R is transferred to a tertiary care facility for neurologic evaluation and observation. Ms. R repeatedly presents a photograph that she claims to be of her deceased child and implores the allied treatment team to advocate for discharge. Evaluation of Ms. R’s neurologic symptoms revealed no medical explanation for the “seizure-like spell” and she is transferred to the inpatient psychiatric hospital.

Upon return to the inpatient psychiatric unit, Ms. R receives intensive psychological exploration of her symptoms, thought content, and the foundation of her pregnancy claim. Within days, she acknowledges that the pregnancy was “not real” and that she was conscious of this fact in the months prior to hospitalization. She cites turmoil in her romantic relationship as the primary stimulus for her actions.

The authors’ observations
Ms. R’s reported pregnancy was not a delusion, but rather a deceitful exposition constructed with appropriate reality testing and a conscious awareness of the manipulation. This eliminated delusions as the explanation of her pregnancy claim. Although Ms. R initially rejected evidence refuting her belief of pregnancy, she recognized and accepted reality with appropriate intervention.

Factitious disorder vs malingering
Factitious disorder and malingering can present with intentional induction or report of symptoms or signs of a physical abnormality:

Factitious disorder imposed on the self is a willful misrepresentation or fabrication of signs or symptoms of an illness by a person in the absence of obvious personal gain that cannot be explained by a separate physical or mental illness (Table 2).^3,4

Malingering is the intentional production or exaggeration of physical or psychological signs or symptoms with obvious secondary gain.

Malingering can be excluded in Ms. R’s case: She did not gain external reward by falsely reporting pregnancy. Although DSM-IV-TR (Table 2) assumes that the motivation for the patient with factitious disorder is to assume the sick role, DSM-5 merely states that the she (he) should present themselves as ill, impaired, or injured.^3,4

Ms. R’s treatment team diagnosed factitious disorder imposed on self after careful exclusion of other causes for her symptoms. Bipolar I disorder, most recent episode depressed, also was diagnosed after considering Ms. R’s previous history of manic episodes and depressive symptoms at presentation.

Factitious disorder and other psychiatric conditions often are comorbid. Bipolar disorder, as in Ms. R’s case, as well as major depressive disorder commonly are comorbid with factitious disorder. It is also important to note that factitious disorder often occurs in the context of a personality disorder.⁵

Which of the following medications are FDA-approved for treating factitious disorder?
   a) olanzapine-fluoxetine combination
   b) lurasidone
   c) valproic acid
   d) all of the above
   e) no medications are approved for treating factitious disorder

TREATMENT Support, drug therapy
Treatment of Ms. R’s factitious disorder consists of psychological interventions via psychotherapy and strengthening of social support. She participates in daily individual therapy sessions as well as several group therapy activities. Ms. R engages with her social worker to facilitate a successful transition to an appropriate support network and access community resources to aid her wellness.

The treatment team feels that her diagnosis of bipolar I disorder, most recent episode depressed, warrants pharmacologic intervention. Ms. R agrees to begin a mood stabilizer, valproic acid, instead of medications FDA-approved to treat bipolar depression, such as lurasidone or quetiapine, because she reports good efficacy and tolerability when she took it during a major depressive episode approximately 4 years earlier.

Valproic acid is started at 250 mg/d and increased to 1,000 mg/d. Ms. R tolerates the medication without observed or reported adverse effects.

The authors’ observations
Managing factitious disorder can be challenging; patients can evoke strong feelings of countertransference during treatment.^3,6,7 Providers might feel that the patient does not need to be treated, or that the patient is “not really sick.” This may induce anger and animosity toward the patient (therapeutic nihilism).⁸ These negative emotions are likely to disrupt the patient–provider relationship and exacerbate the patient’s symptoms.

It is generally accepted that the patient should be made aware of the treatment plan, in an indirect and tactful way, so that the patient does not feel “outed.” Unmasking the patient—the process of instilling insight—is a delicate step and can be a stressful time for the patient.⁹ A confrontational approach often places the patient’s sick role in doubt and does not address the pathological aspect of the disorder.
