Behavioral Dynamics Exam 3 Cards Flashcards
Somatization
Physical symptoms that may not be fully explained by a known medical dx after appropriate workup and cause significant distress and functional impairment
Somatization in actual medical conditions
Often severity of pain/symptoms is out of proportion to the disease
3 factors that can influence somatoform disorder development
Family member with chronic illness
History of abuse or sexual trauma
Comorbid psych disorder
Somatic symptom disorder (Somatization)
Multiple unexplained physical symptoms - often in patients accompanied by a sense of urgency with unstable or dyfunctional families
Classic patient for somatic symptom disorder
Pt. describes being sickly their whole life and has had multiple invasive studies/diagnostics
Criteria for Somatic symptom disorder
1+ symptom that causes significant distress or disruption
Persistent thoughts, anxiety, or energy focused on concerns
Symptoms present for over 6 months
Mild somatic symptom disorder
1 of the three criteria (thoughts, anxiety, energy)
Moderate somatic symptom disorder
2+ of the three criteria (thoughts, anxiety, energy)
Severe somatic symptom disorder
2+ of the three criteria (thoughts, anxiety, energy) and multiple complaints or one SEVERE complaint
Treatment for somatic symptoms disorder
Consolidate care to ONE provider
Have frequent follow up visits
Only order tests objectively
Treat comorbid psych disorders
Functional Neurological Symptom Disease (Conversion disorder)
Altered VOLUNTARY motor or sensory function with no underlying biological cause apparent
Etiology of functional neurological symptom disease
May be a result of physical trauma or an impaired ability to communicate distress
Presentation of functional neurological symptom disease
Neurologic symptoms that do not correlate with exam findings - (ie. DTRs in a paralyzed leg, seizures with normal brain activity)
Hoover’s sign
Hip extension is weak when tested directly but normal when asked to flex the opposite hip
Criteria for Functional Neurologic Symptom Disorder
1+ deficits that are incompatable with a recognized neurological condition, not explained better by another illness and cause significant distress or impairment
Treatment for functional neurological symptom disorder
Psychotherapy - don’t tell patients what it’s imaginary
Illness anxiety disorder (Hypochondriasis)
Preoccupation with serious illness with minimal to no somatic symptoms to support this concern
Classic presentation of illness anxiety disorder
Misinterpretation of benign symptoms, give extremely detailed hx, unswayed by objective findings

Preoccupation that is excessive or disproportionate to the symptoms, anxious about health status, more than 6 months, Excessive participation or avoidance of healthcare
Management for Illness anxiety disorder
Avoid psych referral
Have frequent meetings
Only do objective diagnostic studies
Body dysmorphic disorder
Classified with OCD, preoccupation with perceived appearance defects not readily visible to others
Clinical presentation of body dysmorphic disorder
Vague complaints about body parts, obsession or avoidance of mirrors and avoidance of public interaction
Criteria for body dysmorphic disorder
Preoccupation with 1+ perceived defect, Repetitive behaviors tied to that defect, causes impairment and is not better explained by another condition (ie. anorexia)
Treatment for body dysmorphic disorder
Correction almost never helpful, off lable SSRI use, psychotherapy
Somatic symptom disorder with predominant pain (pain disorder)
Abnormal response, usually to pain that is part of an existing medical condition
Classic presentation of somatic symptom disorder with predominant pain
history of med/surg care, state that life would be good without the pain, psych plays a major role in pain which is not feigned
Criteria for somatic symptom disorder with predominant pain
1+ somatic symptoms predominantly involving pain that causes distress or disruption of daily life, leads to persistent thoughts and takes up excessive time and energy for over 6 months
Treatment for somatic symptom disorder with chronic pain
NSAIDS first line anelgesics, avoid opioids
Cymbalta is indicated for chronic pain, TCAs or SSRIs also helpful
2 things to rule out when considering a diagnosis of a somatic symptom or related disorder
Actual medical problem
Substance use
Factitious disorder (formerly Munchausen syndrome)
Intentionally faking symptoms to appear ill without motivation to gain rewards (insurance money, etc.)
Factious disorder by proxy
Form of ABUSE
Inducing symptoms on others to make them appear sick
Clinical presentation of factitious disorder
Multiple facilities, multiple providers, frequent moves and vague hx
Patients have rare disorders and want a comprehensive workup
4 Common symptoms with factitious disorder
Poor wound healing, , hypoglycemia, GI symptoms, adverse to psychiatric consult
Severe factitious disorder
Wandering with aliases from hospital to hospital - can become aggressive, get admitted and then leave AMA
Signs of factitious disorder imposed on another
S/S worsen when perpetrator is around or when patient has testing or is scheduled for discharge
S/S improve when perpatrator is not around - they show disregard for the patients actual health and are surprisingly agreeable to invasive procedures
Malingering
Faking an illness or symptoms for personal gain - avoids excessive diagnostic tests. S/S improve once goal is acheived
Treatment for malingering
Treat underlying conditions, and avoid manipulation
Treatment for factitious disorders
REPORT by proxy
Be compassionate in discussing diagnosis and try to keep them with one provider2
6 symptoms that can point to psychosis
Hallucinations, Delusions, Disorganized or incoherent speech, disorganized or catatonic behavior, Abnormal emotions, Cognitive difficulties
Hallucination

Believed to be a potential lack of function of the glutamate receptor
Glutamate is an excitatory neurotransmitter
GABA hypothesis of schizophrenia
Decreased function or synthesis of GABA with is an inhibitory neurotransmitter
Acetylcholine hypothesis of schizophrenia
Developed based on the affinity for smoking in schizophrenic patients - unsure how much of a role nicotinic receptors play
Structural brain abnormalities of schizophrenia
