Somatic Symptom & Related Disorders

Real physical symptoms, or fear of illness, that take over daily life — not produced on purpose. Only factitious disorder and malingering are intentional.

What you'll see

Symptoms or fears that take over daily life

Somatic symptom disorder: distressing symptoms + excessive worry, 6+ months hallmark
Illness anxiety disorder: fear of serious illness, few or no symptoms
Body checking and reassurance seeking despite normal results
Secondary gain (attention, excused duties) reinforces symptoms

Pain is the most common complaint in somatic symptom disorder; most patients have several symptoms and have seen multiple providers for them. Risk factors include childhood abuse, neglect or trauma, coexisting anxiety or depression, and family members who model or reward illness behavior.

03

Conversion disorder

A sudden neurologic deficit after a stressor

Sudden paralysis, blindness, numbness or nonepileptic seizures after a stressor
La belle indifférence: apparent lack of concern about the deficit
Also called functional neurological disorder

La belle indifférence supports the diagnosis but is no longer required. Nonepileptic seizures show no epileptic activity on EEG and typically lack postictal confusion, tongue biting and incontinence. Primary gain: the symptom relieves anxiety by keeping the conflict out of awareness; secondary gain: attention or excused duties.

04

Red flags

Caregiver fabricating or inducing a child's illness: protect the child child safety
Document objectively and report suspected abuse mandatory report
Repeated hospitalizations, no firm diagnosis, no response to treatment FDIA clue
Caregiver who seems deeply concerned and protective FDIA clue

Factitious disorder imposed on another (FDIA, formerly Munchausen by proxy): the caregiver may falsify the history, tamper with specimens, or give the dependent drugs or other substances. The diagnosis belongs to the caregiver; child protective services becomes involved.

05

Treatment

CBTfirst-line therapy

Cognitive behavioral therapy for thoughts, feelings and behavior

SSRIscoexisting anxiety or depression
SSRIs

SSRIs treat the anxiety or depression that comes with it

Check-insscheduled, not symptom-driven

Regular, time-limited visits with one consistent provider

Copingthe here and now

Relaxation, deep breathing or guided imagery

Medication cautions and conversion therapy
Start antidepressants low and increase slowly — side-effect sensitive
Avoid benzodiazepines, opioids and other sedatives
Conversion: CBT plus physical therapy for motor symptoms
Conversion symptoms can reverse — there is no structural damage
06

Nursing priorities

Suspected FDIA: protect the child, document, report
Acknowledge the symptoms as real — never say nothing is wrong
Rule out physical disease once, then avoid repeat tests
Schedule time-limited check-ins instead of on-demand visits
Redirect to feelings, stressors and coping
Praise self-care efforts rather than rewarding the sick role
07

Teach your patient

Your symptoms are real and not produced on purpose
Keep scheduled visits with one provider
Use relaxation and deep breathing when symptoms flare
CBT helps symptoms and daily functioning
Pearl

Real to the patient, not on purpose — acknowledge it, skip the repeat test, talk about the stress. Factitious = sick role; malingering = external reward. A caregiver inducing a child's illness: protect and report.
