Test 3 Flashcards
symptoms can include delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior trouble (catatonia) with thinking and concentration, and lack of motivation (dimunition loss of function). broughout on by social or environmental that may precipitate prodromal symptoms ex. going away, substance, death
what is it? what causes it?
schizophrenia: biologically (10x chance of developing it). A chronic w/ chronic, relapsing remitting course w/ no cure (exacerbations and resmisions w/ further deterioration in baseline functioning after each relapse). equal men (earlier onset 10-25) and women (25-35). more likely to be born in the winter and early spring, more addicted to nicotine, and in urban settings. Exposure to viruses (prenatal exposure), malnutrition before birth or other problems, psychosocial factors.
must be 2+ of the following w/ 1, 2, or three required

what is it where is it seen more? what is one thing to note?
brief psychotic disorder
- May be seen more in:
- Individuals of low socio-economic status
- Individuals who have experienced disasters or major cultural changes (immigrants, refugees)
- Individuals who have experienced major psychosocial stressors
full return to premorbid level of functioning
One thing to note: Note: Do not include a symptom if it is a culturally sanctioned response: “for example, in some religious ceremonies, an individual may report hearing voices, but these do not generally persist and are not perceived as abnormal by most members of the individual’s community. In addition, cultural and religious background must be taken into account when considering whether beliefs are delusional.”
- False, fixed beliefs not keeping with one’s culture
- Persist for at least 1 month
- The presence of one (or more) delusions with a duration of 1 month or longer.
- Criterion A for schizophrenia has never been met (positive symptoms)
- Functioning is not markedly impaired.
- Behavioris not obviously bizarre or odd.
patients are difficult to treat
What are the types of delusional disorder?
- Erotomanictype: Central theme of the delusion is that another person is in love with the individual.
- Grandiose type: Central theme of the delusion is the conviction of having some great (but unrecognized) talent or insight or having made some important discovery.
- Jealous type: Central theme of the individual’s delusion is that his/her spouse/lover is unfaithful.
- Persecutory type: Central theme of the delusion involves the individual’s belief that he or she is being conspired against, cheated, spied on, followed, poisoned or drugged, maliciously maligned, harassed, or obstructed in the pursuit of long-term goals.
- Somatic type: This subtype applies when the central theme of the delusion involves bodily functions or sensations.
- Mixed type: This subtype applies when no one delusional theme predominates.
Unspecified type: This subtype applies when the dominant delusional belief cannot be clearly determined or is not described in the specific types
- Features of both schizophrenia and mood disorders
- Schizophrenia + depression orbipolar disorder
- An uninterrupted period of illness during which there is a major mood episode (major depressive or manic) concurrent withCriterion A of schizophrenia.
- Delusions or hallucinations for 2+ weeks in the absence of a major mood episode (depressive or manic) during the lifetime duration of the illness.
- Symptoms that meet criteria for a major mood episode are present for the majority of the total duration of the active and residual portions of the illness.
What is it? who is it most common in? what are the subtypes?
- •Psychotic symptoms and mood symptoms can exist independentlyof each other
- •Treat mood symptoms only àpsychotic symptoms still exist
- •Treat psychotic symptoms only àmood symptoms still exist
Depressive subtype more common in women
- Bipolar type: A manic episode is part of the presentation. Major depressive episodes may also occur.
- Depressive type: Only major depressive episodes are part of the presentation.
What is psychosomatic medicine?
- How the mind affects the body
- Patients with these disorders are often frustrated: “they told me it was all in my head”
What is consultation-liasion psychiatry?
- The study, practice, and teaching of the relation between medical and psychiatric disorders
- Consult on patients in medical or surgical settings and provide follow-up psychiatric treatment as needed
- Bridge between psychiatry and other specialties (education of other specialties)
- Large amount of consults on patients with psychosomatic complaints/disorders
- Patients believe that they have a serious undetected disease and often cannot be persuaded otherwise, even by negative workups
- Symptoms can be specific (localized pain) to nonspecific (fatigue)
- Patients may seek care from multiple doctors for the same symptoms
- More frequent in individuals with few years of education and low socioeconomic status
- More frequent in those who have recently experienced stressful life events
- Can also be associated with a history of childhood trauma or sexual abuse ex. Thoughts and feelings depressed, unconscious way or trauma
- Disproportionate and persistent thoughtsabout the seriousness of one’s symptoms
- Persistently high level of anxietyabout health or symptoms
- Excessive time and energydevoted to these symptoms or health concerns
- low threshold for physical discomfort
- social learning of “sick role” modeled after parent, level, or friend
- men and women equally 20-30
- agressive and hostile wishes toward others transferred (through repression and displacement into physical complainnts (mind-body connection))
somatic symptoms disorder- •Excessivethoughts, feelings, or behaviors related to the somatic symptoms by more than 1 of the following persistently symptomatic more than 6 months:
80% have coexisting depression or anxiety.
can be viewed as a defense against guilt, sense of innate badness, an expression of low self-esteem, sign of excessive self concern.
What is your differential for people w/ somatic symptom disorder?
- •General medical conditions
- •Need to rule out zebras before diagnosing somatic symptom disorder
- •Ex: AIDS, myasthenia gravis, multiple sclerosis, degenerative diseases of the nervous system, lupus, occult neoplastic disorders
- •Need to rule out zebras before diagnosing somatic symptom disorder
- •Illness anxiety disorder-hypochrondriac
- •Fear of having a disease rather than a concern about many symptoms
- •Conversion disorder
- •Presenting symptom is loss of function (ex: of a limb)
- àSomatic symptom disorder: focus is on the distressthat particular symptoms cause
- •Presenting symptom is loss of function (ex: of a limb)
- •Panic disorder
- •Somatic symptoms and anxiety occur in acute episodes
- àSomatic symptom disorder: anxiety and somatic symptoms are more persistent
- •Somatic symptoms and anxiety occur in acute episodes
- •Delusional disorder
- •In somatic symptom disorder, beliefs are not held with delusional intensity
How long does somatic symptom disorder progress? What are the treamtent?
- Episodic; episodes can last for months to years with equally long symptom-free periods
- There can be an association between exacerbations and psychosocial stressors (more stress = worse symptoms)
- A good prognosis is associated with:
- •Higher socioeconomic status
- •Treatment-responsive anxiety or depression
- •Sudden onset of symptoms
- •Absence of a personality disorder
- •Absence of a related non-psychiatric medical condition
- Treatment
- •Many patients resist psychiatric treatment)- believe underlying medical cause
- •Psychotherapy
- •Treat underlying/comorbid depression/anxiety (sometimes it is enough)
- •Consider regularly scheduled physical examinations help to reassure patients that their physicians are not abandoning them and that their complaints are being taken seriously
- •Invasive diagnostic and therapeutic procedures should only be undertaken if there is objective evidence after diagnosis is made
pain in one or more body sites severe enough to be brought to clinical attention.
- Excessivethoughts, feelings, or behaviors related to the somatic symptoms or associated health concerns as manifested by 1+ of the following:
- Disproportionate and persistent thoughtsabout the seriousness of one’s symptoms
- Persistently high level of anxietyabout health or symptoms
- Excessivetime and energy devoted to these symptoms or health concerns
Somatic symptom disorder with predominant pain(previously pain disorder): this specifier is for individuals whose somatic symptoms predominantly involve pain
•Psychological factors are necessary in the genesis, severity, or maintenance of the pain, which causes significant distress, impairment, or both
Note: symptoms of irritable bowel syndrome or fibromyalgia would not satisfy the criterion necessary to diagnose somatic symptom disorder
- Preoccupation with having or acquiring a serious illness
- Somatic symptoms are not present or mild in intensity
- There is a high level of anxiety about health, and the individual is easily alarmed about personal health status. slightest pain or discomfort is a worse disease
- The individual performs excessive health-related behaviors(ex: repeatedly checks body for signs of illness) or exhibits maladaptive avoidance (ex: avoids doctor appointments and hospitals)
- Illness preoccupation has been present for at least 6 months, but the specific illness that is feared may change over that period of time.
what is it? what does it categorize? how do you treat it?
illness anxiety disorder
- Similar prevalence in males and females
- Distress does not primarily come from the physical complaint itself but rather from the anxiety about the meaning, significance, or cause of the complaint
- Concerns do not respond to appropriate medical reassurance/workup
- Can be precipitated by a major life stress or a serious but ultimately benign threat to the individual’s health
- A history of childhood abuse or of a serious childhood illness may predispose one to the development of the disorder in adulthood
- Generally thought to be chronic and relapsing similar to somatic symptom disorder
Treatment
- Patients tend to resist treatment
- Psychotherapy +/- pharmacotherapy
- Regularly scheduled examinations are more controversial; may help some patients while exacerbating fears in others
What is the differential diagnosis of illness anxiety disorder?
- •General medical conditions
- •Obsessive compulsive disorder
- •Illness anxiety: preoccupations are focused on having a disease presently
- •OCD: intrusive thoughts focused on fear of getting a disease in the future
- •Most individuals with OCD have obsessions or compulsions involving other concerns
- •No compulsions in illness anxiety disorder
- •Illness anxiety: preoccupations are focused on having a disease presently
- •Psychotic disorders
- •Illness anxiety disorder: not delusional, can acknowledge the possibility that the feared disease is not present
- •Ideas do not attain the rigidity and intensity seen in the somatic delusions occurring in psychotic disorders
- •True somatic delusions are generally more bizarre (an organ is rotting or dead)
- Psychoanalytic factors
- Repression of an unconscious conflict àconversion of anxiety into physical symptoms
- Learning theory
- Symptoms of illness learned in childhood àway to cope with a difficult situation
- Biological factors
- Symptoms may be caused by an excessive cortical arousal that sets off negative feedback loops between the cerebral cortex and the brainstem reticular formation àinhibits awareness of bodily sensation (can explain observed sensory deficits)
- Maladaptive personality traits are commonly associated with conversion disorder (personality disorder develop after the fact)
- There may be a history of childhood abuse and neglect
- Stressful life events are often (but not always) present
- Sensory symptoms
- Anesthesia/paresthesia common in extremities
- Symptoms can be unilateral or bilateral
- Sensory pathways intacton neurologic exam
- Motor symptoms
- Abnormal movements, gait disturbance, weakness, paralysis
- The movements generally worsen when attention is called to them
- Reflexes remain normal; no fasciculation or muscle atrophy; EMG normal
- Seizure symptoms (PNES = psychogenic non-epileptic seizures)- pseudo-seizures
- Non-epileptic seizures are common
- 1/3 of patients with PNES also have epilepsy (can have insight into both)
- Tongue-biting, urinary incontinence, and falling injuries are typically not present in PNES
- La belle indifference: inappropriately cavalier attitude toward serious symptoms; the patient seems to be unconcerned about what appears to be a major impairment
conversion disorder
- One or more symptoms of altered voluntary motor or sensory function
- Clinical findings provide evidence of incompatibilitybetween the symptom and recognized neurological or medical conditions
àNeuro symptoms with a negative neuro workup (nonepipiletpticseizures, inability to walk, etc.)
- The symptom or deficit causes clinically significant distress or impairment in functioning or warrants medical evaluation
- May account for 5-15% of psychiatric consultations in a hospital setting
- More common in women
- Onset is typically from late childhood to early adulthood
- Most common among:
- Rural populations
- Persons with little education
- Low socioeconomic groups
- Military personnel who have been exposed to combat situations
Commonly associated with comorbid diagnoses of depression and anxiety
- Course/Prognosis
- Acute onset
- Typically short duration; most symptoms remit spontaneously within 2 weeks of hospitalization
- Symptoms resolution is less than 50% in patient who have symptoms > 6 months
- Longer duration of symptoms = less chance of recovery
- Good prognosis:
- Acute onset
- Presence of clearly identifiable stressors at the time of onset
- Short interval between onset and treatment
- Above average intelligence
- Treatment
- Psychotherapy
- Physical therapy
- Treat any underlying anxiety/depression
What is the differential diagnosis of conversion disorder?
- •Neurological disease
- •Needs to be ruled out
- •Somatic symptom disorder
- •The excessive thoughts, feelings, and behaviors in somatic symptom disorder are often absentin conversion disorder
- •Most of the somatic symptoms in somatic symptom disorder cannot be demonstrated to be clearly incompatible with pathophysiology (pain, fatigue); in conversion disorder, such incompatibility is requiredfor the diagnosis
- •Factitious disorder/malingering
- •In conversion disorder symptoms are NOT intentionally produced
- •Depressive disorder
- •Can have general heaviness of limbs in depression; conversion disorder loss of function is focal and prominent
- •Panic disorder
- •Paresthesias/tremors are transient in panic disorder
- Falsificationof physical or psychological signs or symptoms, or induction of injury or disease, associated with identified deception
- The individual presents himself or herself to others as ill, impaired, or injured
- The deceptive behavior is evident even in the absenceof obvious external rewards
- Unusual, dramatic presentation of symptoms that defy conventional medical or psychiatric understanding
- Symptoms do not respond appropriately to usual treatment or medications
- Emergence of new, unusual symptoms when other symptoms resolve
- Eagerness to undergo procedures or testing or to recount symptoms
- Reluctance to give access to collateral sources of information (i.e., refusing to sign releases of information or to give contact information for family and friends)
- Extensive medical history or evidence of multiple surgeries
- Multiple drug allergies
- Medical profession
- Few visitors
- Ability to forecast unusual progression of symptoms or unusual response to treatment

Factitious disorder imposed on self = Munchausen syndrome
Imposed on another = Munchausen by proxy
- Consider history of childhood abuse/neglect/trauma
- Course/Prognosis
- Typically intermittent episodes
- Onset is usually in early adulthood after a hospitalization for a medical or psychiatric disorder
- Lifelong hospitalizations with some patients, particularly factitious disorder imposed on self (give themselves serious infections)
- Treatment
- No specific treatment is effective
- Focus instead on management:
- Reduce the risk of morbidity and mortality
- Avoid unnecessary tests and invasive procedures
- Address underlying psychiatric diagnoses
What are the differential diagnosis of factitious disorder?
- •Somatic symptom disorder
- •Patient is not providing false information or behaving deceptively
- •Malingering
- •Personal gain ($$$, time off of work, etc.)
- •No personal gain in factitious disorder
- •Conversion disorder
- •No falsification of symptoms in conversion disorder
- •Borderline personality disorder
- •Self-harm without suicidal intent (cutting) is common, but no deception
- •Medical/psychiatric diagnoses
- •May still be present
What is it given the following:
DSM-5 Criteria:

Anorexia Nervosa
What are the two main types of Anorexia Nervosa?
What are the severity in adults?
- Restricting type: Weight loss through dieting, fasting, and/or excessive exercise
- Binge-eating/purging type: During the last 3 months, the individual has engaged in recurrent episodes of binge eating or purging behavior (self-induced vomiting or the misuse of laxatives, diuretics, or enemas)
Severity (adults)
- Mild: BMI ≥ 17 kg/m2
- Moderate: BMI 16–16.99 kg/m2
- Severe: BMI 15–15.99 kg/m2
- Extreme: BMI < 15 kg/m2
Explain the epidemiology of Anorexia Nervosa
Explain the comorbidities of Anorexia Nervosa
Epidemiology
- Most common age of onset 14-18 years old, range 10-30 years
- Estimated to occur in 0.5-1% of adolescent girls
- 10-20x more common in females
- The prevalence of young women with some symptoms of anorexia nervosa who do not meet the diagnostic criteria is estimated to be ~5%
- More frequent in developed countries
- More common in professions that “require” thinness (modeling, elite athletics)
Comorbidities
- Depression, anxiety, OCD
Explain the etiology of Anorexia Nervosa
Etiology
“Genetics loads the gun, environment pulls the trigger”
- Evidence for a genetic component
- Environmental factors:
- Teasing
- Psychosocial factors
- Societal pressure
- Intensive exercise/food restriction (results will help them develop it)
- Substance abuse
Given these clinical features, what disorder are we speaking of?
- Onset can be related to a stressful life event (ex: leaving for college, moving, breakups)
- Intense fear of gaining weight or being fat that is not relieved by weight loss
- Peculiar behavior about food: hiding food around home, hiding food in napkins/pockets, rearranging food with poor insight into these behaviors
- Patients tend to be perfectionists
- Delayed psychosocial sexual development
- Taking a sexual history can distinguish between anorexia and belemia
- Amenorrhea
- Cold intolerance
Anorexia Nervosa
Given these clinical findings, what disorder are we talking about?
Physical Findings
- Bradycardia
- Hypotension
- Lanugo- fine hair growing everyone on skin
- Dry skin, scaling skin
- Dry hair- thinning, falling out
- Low body temperature/difficulty regulating
- Peripheral edema
- Body is slowing down to conserve energy
Anorexia Nervosa
Given the following image, what disorder are we speaking of?
Anorexia Nervosa
What are the cardiovascular and gastrointestinal effects of Anorexia Nervosa?
Cardiovascular effects
- Decreased cardiac output
- EKG changes
- T wave flattening/inversion (torsades)
- ST depression
- QT prolongation 🡪 risk of arrhythmias
Gastrointestinal effects
- Early satiety
- Constipation
Given the following information, what disorder are we referring to?
Differential Diagnoses
- Medical conditions
- Hyperthyroidism, occult malignancies, GI disease, HIV
- 🡪 Thinking about underlying causes of weight loss
- Depression
- Decreased appetite of depression can differentiate
- In depression there is no fear of obesity or body image disturbance (mood versus weight)
- Anxiety/OCD
- Many similar symptoms; with eating disorders the symptoms are only related to food
- Consider additional diagnosis of OCD only if the obsessions and compulsions are unrelated to food
- Somatization disorder
- Weight loss is typically not as severe in somatization disorder
- No fear of being overweight
- Amenorrhea is uncommon
- Schizophrenia
- May have bizarre eating habits or delusions about food, but typically about food being poisoned
- No fear of weight gain
- Bulimia nervosa
- Typically maintain near-normal body weight
Anorexia Nervosa
Given the course/prognosis, what is the disorder we are referring to?
Course/Prognosis
- Highly variable
- Restricting patients may be less likely to recover
- Mortality rate 5-18%
- Indicators of a favorable outcome:
- Admission of hunger (improving insight)
- Lessening of denial and immaturity
- Improved self-esteem
- ¼ of patients recover completely
- ½ are markedly improved and functioning fairly well
- ¼ are functioning poorly and chronically underweight
Anorexia Nervosa
What are the levels of treatment for Anorexia Nervosa?
Tell the four levels then facts about each
Levels of treatment
- Medical hospitalization
- Weight loss > 30% in 3 months or body weight less than 75% expected
- Severe metabolic changes: K < 2.5, BUN > 30, or other signs of dehydration would otherwise necessitate hospitalization
- HR < 40, SBP < 70; ekg changes (treatment team in the hospital)
- Inpatient residential treatment
- Weight > 75th %ile
- Patient requires structure to comply with eating plan / unstable home environment
- Combo of a behavioral management approach, individual psychotherapy, family education/therapy, and psychotropic medications if indicated
- Patients must be willing participants for long-term treatment success
- Intensive outpatient care
- Medically stable, body weight at least 80% of healthy weight
- Patient goes to outpatient center daily for meals, therapy
- Outpatient care
- Body weight > 85%ile
- Fair to good motivation
- Able to follow meal plan (eat 2/3 of meals there); supportive home structure
What is the treatment for Anorexia Nervosa?
Psychotherapy
- Individual and family therapy
Pharmacotherapy
- Treat any underlying psychiatric comorbidities
- No serotonin synthesis with poor nutrition… SSRI wont work and wont be as efficatious🡪 Need to eat for meds to work!
- TCAs and antipsychotics have been used for weight gain
- Be aware of side effects in patients with anorexia who are already susceptible to dehydration, cardiac arrhythmias, and hypotension
What is it given the following?
DSM-5 Criteria:
- Recurrent episodes of binge eating:
- “Eating large amounts of food in a discrete period of time that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances.”
- Lack of control, cannot stop eating
- Recurrent, inappropriate compensatory behaviors to prevent weight gain
- Self-induced vomiting
- Misuse of laxatives, diuretics, or other medications
- Fasting
- Excessive exercise
- The binge eating and inappropriate compensatory behaviors both occur at least once per week for 3 months
- Self-evaluation is highly influenced by body shape and weight
Bulimia Nervosa
Explain the severities of Bulimia Nervosa
Explain the Epidemiology as well
- Mild: An average of 1-3 episodes of inappropriate compensatory behaviors per week.
- Moderate: An average of 4-7 episodes of inappropriate compensatory behaviors per week.
- Severe: An average of 8-13 episodes of inappropriate compensatory behaviors per week.
- Extreme: An average of 14 or more episodes of inappropriate compensatory behaviors per week.
Epidemiology
- More prevalent than anorexia nervosa
- 1-4 % of young women
- More common in women than men
- Onset is often later in adolescence or early adulthood
- Approximately 20% of college women experience transient bulimic symptoms at some point during their college years
- Can be a history of obesity leading to it,
Given the etiology, what is the disorder we are referring to:
Etiology
- Combination of biological, social, and psychologic factors
- Increased frequency of bulimia nervosa is found in first-degree relatives of persons with the disorder
- Childhood obesity and early puberty increase risk
- Tend to be high achievers and to respond to societal pressures to be slender
- Tend to be more outgoing, angry, and impulsive than those with anorexia nervosa
- Alcohol dependence, shoplifting, and emotional lability (including suicide attempts) can be associated

Bulimia Nervosa
Given the following image, what disorder are we referring to?
Also note these Medical Consequences as well:
- Gastric dilatation, pancreatitis after binging episodes

Bulimia Nervosa
What are the following electrolyte disturbances with Bulimia Nervosa?
Diuretic abuse
Laxative Abuse
Vomiting
- Diuretic abuse
- Dehydration (NaCl, K depletion)
- Hyperaldosterone
- Renal impairment
- Laxative abuse
- Metabolic acidosis (loss of HCO3)
- Loss of Mg, zinc, Na
- Dehydration
- Vomiting
- Metabolic alkalosis (loss of HCl)
- Dehydration (loss of Na, K)
Given the differential diagnoses, what disorder are we speaking about?
- Anorexia nervosa, binging/purging type
- Binging/purging only occurs during episodes of anorexia nervosa
- Weight differences
- “Individuals whose binge-eating behavior occurs only during episodes of anorexia nervosa are given the diagnosis anorexia nervosa, binge-eating/purging type, and should not be given the additional diagnosis of bulimia nervosa. For individuals with an initial diagnosis of anorexia nervosa who binge and purge but whose presentation no longer meets the full criteria for anorexia nervosa, binge-eating/purging type (e.g., when weight is normal), a diagnosis of bulimia nervosa should be given only when all criteria for bulimia nervosa have been met for at least 3 months.” –DSM 5
- Binge eating disorder
- No purging behaviors
- Kleine-Levin syndrome
- Rare neurological disorder
- Periodic hypersomnia lasting for 2 to 3 weeks and hyperphagia
- No preoccupation with body shape or weight
- Seasonal affective disorder
- Overeating/binging during winter months
- Not overly concerned with body shape or weight; typically no purging
- Borderline personality disorder
- Both may have impulsive behavior
- Patients with bulimia nervosa often meet criteria for borderline personality disorder
Bulimia Nervosa
Given the course/prognosis/treatment, what is the disorder we are referring to?
- Higher recovery rates
- Treatment increases rate of recovery
- History of substance abuse and a long duration of ____ predict a worse outcome
- Mortality rate is about 2% per decade (all-cause and suicide)
Treatment:
- Eating disorder inpatient/outpatient treatment
- Psychotherapy
- Pharmacotherapy
- SSRIs may be helpful in reducing binging and purging even in the absence of a mood disorder
Bulimia Nervosa
What is it given the following?
DSM-5 Criteria:
