Somatic Symptom and Related Disorders

  • Previously categorized as Somatoform Disorders.

  • Features: Distressing somatic symptoms that encompass a prominent focus on physical symptoms associated with significant distress and impairment.

  • Characteristic Elements:

    • Maladaptive thoughts, feelings, and behaviors in response to these symptoms.

    • Commonly seen in medical settings due to high rates of medical comorbidity.

Treatment Challenges of Somatic Symptom Disorders

  • Treatment can be difficult because of the prominent focus on physical symptoms.

  • Does not necessitate an absence of physical disease for diagnosis.

  • Symptoms are not consciously controlled, ruling out a purely psychological cause.

  • Diagnostic matters require ruling out serious physical illnesses, such as:

    • Multiple Sclerosis

    • CNS Syphilis

    • Brain Tumors

    • Systemic Lupus Erythematosus

    • Myasthenia Gravis

Contributing Factors to Somatic Symptom Disorders

  • Genetic predisposition including increased sensitivity to pain.

  • Impact of early life experiences and past traumas.

  • Attention received while ill versus neglect when well.

  • Cultural norms influencing perception of psychological versus somatic symptoms.

Interaction with Other Disorders

  • Somatic symptoms often complicate depressive and anxiety disorders, leading to increased severity and functional impairment.

  • Chronic stress can exacerbate symptomology and treatment resistance.

Key Terminology

  • Disease: Refers to pathophysiological processes with identifiable lesions.

  • Illness: The individual's response to symptoms and the family’s interpretation.

  • Illness Behavior: How patients perceive, evaluate, and respond to their health status.

  • Abnormal Illness Behavior: Based on a maladaptive interpretation of health status that persists despite professional advice.

Clinical Syndromes Associated with Somatic Symptom Disorders

  • Somatic Symptom Disorder

  • Illness Anxiety Disorder

  • Conversion Disorder/Functional Neurological Symptom Disorder

  • Psychological Factors Affecting Other Medical Conditions

Somatic Symptom Disorder (SSD)

  • Characterized by one or multiple severe somatic symptoms causing significant disruption in daily life.

  • Symptoms can be specific (e.g., local pain) or vague (e.g., fatigue).

  • Individuals may have disproportionate thoughts and persistent anxiety related to the severity of the symptoms.

  • Distress is focused on the somatic symptoms and perceived significance.

  • Symptoms may exist without an identifiable medical condition but suffering remains genuine regardless.

  • Diagnosis of SSD can coexist with a medical diagnosis.

  • Prior Diagnoses: Many patients previously labeled with Somatization Disorder now meet SSD criteria.

Historical Context: Somatization Disorder

  • Defined under DSM-IV as a chronic syndrome involving multiple unexplained somatic symptoms.

  • Symptoms must include:

    • Four pain symptoms

    • Two gastrointestinal symptoms

    • One sexual symptom

    • One pseudoneurological symptom

Diagnostic Characteristics of Hypochondriasis (DSM-IV)

  • Excessive preoccupation with health and fears of serious diseases despite lack of evidence.

  • Symptoms must persist for at least six months, with fluctuating rates of exacerbation and remission.

  • Prognosis shows 30-50% improvement over time.

Cognitive Model of Somatic Symptom Disorder

  • Triggers can include information, events, illness, or images that lead to a response pattern such as:

    • Apprehension

    • Increased focus on bodily sensations

    • Physiological arousal

    • Reassurance seeking behaviors

    • Persistent preoccupation with perceived abnormalities.

Medical Care Utilization in SSD

  • Patients often seek reassurance about symptoms, viewing medical interventions as inadequate despite high usage rates.

  • Many show sensitivity to medication side effects and responding poorly to psychiatric referrals.

  • Comorbid depression and high suicide risk are substantial considerations.

Prognostic Factors for Somatic Symptom Disorder

  • Presence of comorbid anxiety and depression amplifies symptom focus.

  • Risk factors include:

    • Low educational achievement

    • Lower socioeconomic status and unemployment

    • History of childhood adversity or sexual abuse

    • Concurrent chronic illnesses.

Management of Somatic Symptom Disorder

  • Brief physical examinations focusing on disease signs rather than symptoms.

  • Avoidance of unnecessary tests and medications, especially habit-forming drugs.

  • Establish clear communication, acknowledging the patient's experience as valid.

  • Schedule regular follow-ups (2-6 weeks) to maintain a steady management course.

  • Single healthcare provider should oversee management to avert confusion and miscommunication.

Illness Anxiety Disorder

  • Preoccupation with serious medical illness without significant somatic symptoms.

  • Symptoms may arise from anxiety and misinterpretation of common bodily sensations.

  • Anxiety regarding medical conditions often exceeds the severity of any existing conditions.

  • Patients frequently engage in excessive self-checking and self-examination behaviors, leading to the chronic nature of anxieties.

  • Risk factors include past physical or emotional stressors and childhood abuse.

Functional Neurological Symptom Disorder (FNSD) / Conversion Disorder

  • Defined as one or more symptoms of altered motor or sensory function inconsistent with known conditions.

  • Symptoms may include paralysis, abnormal movements, or seizures that are not compatible with diagnoses.

  • Often occurs post-stress or trauma, with psychological factors evident but sometimes not immediately identifiable.

  • Assessments typically reveal inconsistencies in clinical findings as a diagnostic hallmark.

Characteristics of Symptoms in Functional Neurological Symptom Disorder

  • Motor Symptoms include:

    • Weakness or paralysis

    • Abnormal movements such as tremors and dystonic movements.

  • Sensory Symptoms include:

    • Altered or absent sensations including vision and hearing.

  • Psychogenic Non-Epileptic Seizure (PNES) characterized by specific motor behavior patterns and absence of postictal states.

Risks and Prognosis for FNSD

  • Risks include association with childhood trauma, personality disorders, and stressful life events.

  • Prognosis is generally favorable with structured management and psychotherapy aimed at coping skills.

Body Dysmorphic Disorder

  • Defined as a strong belief in perceived bodily flaws.

  • Includes conditions where the defect may be imaginary or exaggerated, classified under Obsessive Compulsive and Related Disorders.

  • Epidemiological Statistics: Prevalence approximately 2.4%, higher prevalence within dermatological and surgical patients.

  • Commonly observed traits: Shyness, self-absorption, significant distress regarding perceived flaws, especially facial features.

  • Notable risks include suicide attempts and psychiatric comorbidity (depressive disorders or psychotic symptoms).

Management of Body Dysmorphic Disorder

  • Address concurrent anxiety and depression with treatment, often through SSRIs.

Factitious Disorders

  • Defined as condition where individuals intentionally produce symptoms for the primary purpose of assuming the sick role.

  • Munchausen's syndrome is identified as a severe manifestation of factitious disorder concerning physical symptoms.

  • Clinical characteristics include: Feigned symptoms, manipulation of medical staff, use of props to simulate illness.

Malingering and Its Characteristics

  • Defined as the deliberate fabrication or exaggeration of symptoms for tangible external incentives such as avoiding responsibilities or obtaining medications.

  • Clinical Indicators: Vague symptom complaints that do not match objective findings.

  • Associated with personality disorders, particularly antisocial traits.

Summary of Conditions

  • Somatic Symptom and Related Disorders: Involve physical complaints tied to psychological factors, not intentionally produced.

  • Factitious Disorders: Characterized by intentional symptom production for the assumptive role of a patient.

  • Malingering: Distinguished by intentional symptom fabrication for external motivations.

Somatic Symptom Disorder (SSD)

  • Characterized by one or more severe somatic symptoms causing significant disruption, with disproportionate thoughts and persistent anxiety related to symptoms. Suffering is genuine, and SSD can coexist with medical diagnoses.

  • Management: Brief physical exams focusing on disease signs, avoiding unnecessary tests/meds, clear communication, regular follow-ups with a single provider.

Illness Anxiety Disorder

  • Preoccupation with serious medical illness without significant somatic symptoms, often involving misinterpretation of bodily sensations and excessive self-checking.

Functional Neurological Symptom Disorder (FNSD) / Conversion Disorder

  • One or more symptoms of altered motor or sensory function inconsistent with known conditions, often occurring after stress or trauma, with inconsistencies as a diagnostic hallmark.

Body Dysmorphic Disorder

  • Strong belief in imaginary or exaggerated bodily flaws, classified under Obsessive Compulsive and Related Disorders. Associated with high distress, suicide risk, and psychiatric comorbidity. Management includes addressing anxiety/depression, often with SSRIs.

Factitious Disorders

  • Individuals intentionally produce symptoms to assume the sick role (e.g., Munchausen's syndrome).

Malingering

  • Deliberate fabrication or exaggeration of symptoms for tangible external incentives (e.g., avoiding work, obtaining drugs). Indicators include vague complaints inconsistent with objective findings, often associated with antisocial traits.

Summary of Conditions

  • Somatic Symptom Disorders: Unconscious symptom production and unconscious motivation.

  • Factitious Disorders: Conscious symptom production, unconscious motivation (to assume sick role).
