106b - Somatoform Disorders

Question 1

What motivates patients with factitious disorder?

Answer 1

Desire to have the role of the patinet (primary gain)

Remember: These patients are being unconsciously deceptive; they are not making a conscious effort to lie

(Vs. malingering, where goal is financial, legal - secondary gain)

Question 2

How does illness anxiety disorder differ from somatic symtom disorder or functional neurological disorder?

Answer 2

No physical symtoms present in illness anxiety disorder

• Physical symptoms in SSD (upset stomach, pain, headache)
• Neurological symptoms in FND (can’t lift leg, facial droop)

Question 3

Describe the clinical presentation of factitious disorder

Answer 3

• 1 or more brief episodes
  
  • If multiple episodes, symptoms vary
• May have psychological symptoms, physical symptoms, or both
  
  • May have real medical symptoms (may be self induced)
  • Pt has the unconscious goal of being the patient/being cared for as a patient
• Onset in early adulthood
  
  • Usually after hospitalization

Question 4

Describe the clinical presentation of functional neurological disorder (previously conversion disorder)

Answer 4

• Rapid neurological symptom onset, rapid resolution
  
  • May be in the context of stress
• No neurologic cause (no stroke or motor neuron pathology)
• On exam, positive Hoover’s sign

Not intentionally produced or feigned by the patinet!

Question 5

What is the “classic presentation” of a patinet with somatic symptom disorder?

Answer 5

• Chartomegaly
• Complicated medial history of symptoms that don’t make sense
• Many work-ups, medical/surgical procedures, failed treatments
• Multiple allergies
• Popular, poorly understood diagnoses
  
  • Fibromyalgia, IBD
• Psychiatric history likely

Question 6

What mental status exam findings may be associated with somatic symptom disorder?

Answer 6

• Demanding, histrionic, dramatic
• Seductive dress and manner

1/3 have comorbid neurological disorder in their lifetime

1/2 of non-epileptic seizure pts have epileptic seizures

Question 9

What is Munchausen’s by proxy?

Answer 9

Parent induces medical signs in a child with the purpose of assuming the sick role indirectly

(Munchausen’s is a severe form of factitious disorder)

Question 10

What causes FDN (previously conversion disorder)

Answer 10

May be some or all of the following; key takeaway is that there is a CNS pathology leading to the symptoms

• Altered connectivity between areas involved in emotion, memory, exec control, movement
  
  • Due to disturbances in brain networks
• Disruption in emotional processing
  
  • May be the link between psychosocial risk factors and neuro symptoms

Question 11
