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.
On purpose or not?
Sort by intent, then by motive
| Somatic · illness anxiety · conversion | Factitious disorder | Malingering | |
|---|---|---|---|
| Intentional? | No — symptoms are real to the patient | Yes — fabricates or induces symptoms | Yes — feigns or exaggerates symptoms |
| Motive | None — not under conscious control | The sick role itself | External reward: money, time off, drugs |
| Mental disorder? | Yes | Yes | No — a behavior |
What you'll see
Symptoms or fears that take over daily life
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.
Conversion disorder
A sudden neurologic deficit after a stressor
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.
Red flags
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.
Treatment
Cognitive behavioral therapy for thoughts, feelings and behavior
SSRIs treat the anxiety or depression that comes with it
Regular, time-limited visits with one consistent provider
Relaxation, deep breathing or guided imagery
Medication cautions and conversion therapy
Nursing priorities
Teach your patient
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.

Somatic Symptom & Related Disorders
Somatic symptom and related disorders are mental health conditions in which real physical symptoms, or the fear of a serious illness, cause distress and take over daily life. In somatic symptom disorder, illness anxiety disorder and conversion disorder, the symptoms are genuine to the patient and are not produced on purpose. Conversion disorder shows up as a sudden neurologic deficit, such as paralysis, blindness or a nonepileptic seizure, usually after a stressful event, sometimes with a surprising lack of concern. Two look-alikes are intentional. In factitious disorder the patient fakes or causes symptoms to be cared for as a patient, and in malingering the goal is an outside reward like money or time off work. The nursing approach is the same for the unintentional group: acknowledge the symptoms as real, rule out physical disease once and then avoid repeat testing, schedule regular check-ins with one provider, and gently turn the conversation toward feelings, stress and coping. When a caregiver causes a child's illness, the child's safety comes first, and the nurse documents and reports.
