U-World: Block 9 (Psych) Flashcards
Pattern of arguing and defiance toward authority figures for > 6 months.
Oppositional defiant disorder (ODD)
Violating social norms (aggression to people and animals, destruction of property, theft) in a kid < 18 is called what? How about in an adult > 18?
<18 —> Conduct Disorder
>18 —> Antisocial Personality Disorder
Sleepwalking can occur during what phase of sleep? What sleep waves are going on at this time?
Stage N3 (non-REM) aka “slow-wave sleep” (this is when you’re in your deepest sleep—sleepwalking, night terrors, and bed wetting can happen at this time in the sleep cycle) Delta waves
1st line treatment for depression? What should you screen for before prescribing it and why?
SSRI’s!
Screen for manic episodes in their history (suggesting Bipolar, not just depression) because you never want to give an SSRI to a Bipolar patient because they can trigger a manic episode! (SSRI’s bring you from sad to happy but can make them too happy)
Diaphoresis means what?
Sweating
What are symptoms of “autonomic dysregulation” (such as in serotonin syndrome)?
Sweating (diaphoresis), inc BP (hypertension), inc HR (tachycardia), inc temp/ fever (hyperthermia), vomiting, and diarrhea
What is the presentation of serotonin syndrome (3 A’s)?
Activity (hyperreflexia, tremor, seizure)
Autonomic instability (hyperthermia/ fever, diaphoresis/ sweating, diarrhea, etc.)
Altered mental status
Lady comes in with an empty bottle of SSRIs prescribed to her for depression. She presents with a fever, high BP, high HR, disoriented, tremor, sweating, abdominal cramps and diarrhea, dilated pupils, and hyperreflexia. What does she have?
Serotonin syndrome
What amino acid is the precursor for serotonin synthesis?
Tryptophan
Kid has behavioral and coordination issues. Small height, weight, and head circumference. Short palpebral fissures, smooth philtrum, and thin upper lip. Diagnosis?
Fetal alcohol syndrome (was exposed to alcohol from mom in utero)
Patient is taking SSRIs for depression. What 3 things could cause serotonin syndrome in this patient?
Too much serotonin—> serotonin syndrome
- Overdosing on SSRI’s or combining with another Serotonergic medication (like SNRI, tricyclic antidepressant, or tramadol)
- Taking a MAO Inhibitor (MAO is the enzyme that breaks down Serotonin in the synaptic cleft before it is taken back up by the pre-synaptic neuron, so if you block that process, you increase the serotonin in the cleft)
- Taking the antibiotic Linezolid (acts LIKE an MAO inhibitor)
Anecdote for serotonin syndrome?
Cyproheptadine
A 1st gen anti-histamine with 5-HT1 and 5-HT2 antagonist properties
What is a short-term drug class used to treat Panic disorder that also has muscle relaxant and anti-convulsant properties?
Benzodiazepines (Benzo’s- CNS depressants)
*note that SSRIs and SNRIs are 1st line for panic disorder, but they take 1-2 months to work, so Benzos are ideal for short-term therapy
(Sketchy: Ben’s diner)
What’s the mechanism of action of Benzodiazepines?
Increased frequency of chloride channel opening
They bind to and enhance the activity of GABA-A receptors (Sketchy Ben’s diner: cab-A and Pam cake delivery will enhance the activity of the cab driver). GABA-A receptors are inhibitory (“take it easy”) and are Chloride channels (“Clo-rider”). SO, Benzo’s lead to increased frequency of chloride channel opening (“now open more frequently”).
*note that GABA is inhibitory and Benzo’s stimulate these neurotransmitters, so Benzo’s are CNS depressants (specifically, the influx of chloride will hyperpolarize and stabilize the membrane, making it less excitable)
What class of meds is good for treating alcohol withdrawal syndrome as well as short-term treatment of anxiety disorders?
Benzodiazepines (Ben’s diner in Sketchy)
Unresponsive to pain, constricted pupils, cyanosis bc he’s barely breathing. What drug did the patient overdose on?
Opioids (CNS depressant that binds mu receptors)
What drug is given to reverse acute opioid toxicity/ overdose?
Naloxone (“no lax zone” in Sketchy Utopia Resort sketch)
*it mainly targets mu receptors (where opioids bind to) and antagonizes them

Orientation
Asking a patient to follow multistep commands tests for what?
Comprehension
Asking a patient to recite months of the year backwards tests for what?

What is the main condition anti-psychotics treat?
Schizophrenia
A women with Schizophrenia (taking Risperidone to manage symptoms) comes in to your clinic bc she stopped having periods and her breasts are sore. What is probably causing her symptoms?
Medication side effect.
Risperidone is an anti-psychotic used to treat Schizophrenia. It inhibits D2 dopamine receptors—> increased prolactin (bc dopamine normally inhibits prolactin, but you are putting the brake on dopamine so that it cannot in turn put the brake on prolactin)—> excess prolactin inhibits GnRH—> amenorrhea
What is the way to remember key differences in cluster A, B and C personality disorders?
“Weird (cluster A), Wild (cluster B), and Worried (cluster C)”
Diagnostic criteria for Major Depressive Disorder (MDD)?
Episodes lasting 2 or more weeks with at least 5 of the 9 “SIG E CAPS” depression symptoms.
(SIG E CAPS= 1. depressed mood, 2. Sleep disturbance, 3. loss of Interest, 4. Guilt of feelings of worthlessness, 5. Energy loss and fatigue, 6. Concentration problems, 7. Appetite and weight changes, 8. Psychomotor retardation or agitation (inc or dec motor activity), 9. Suicidal ideation)
What are the 9 symptoms of depression/ Major Depressive Disorder (MDD) remembered by “SIG E CAPS?”
*remember, you need episodes lasting 2 weeks or more with 5 or more of these 9 symptoms.
- depressed mood
- Sleep disturbance
- loss of Interest
- Guilt of feelings of worthlessness
- Energy loss and fatigue
- Concentration problems
- Appetite and weight changes
- Psychomotor retardation or agitation (inc or dec motor activity)
- Suicidal ideation)
Patient is depressed. Before making a diagnosis, what do you want to rule out (a medical reason, rather than psychiatric reason, that may be responsible for the depression)?
Hypothyroidism (check those TSH levels)
How do we diagnose “adjustment disorder?”
Patient has emotional symptoms (anxiety, depression) after (within 3 mo) something happens that triggers it (a stressor like they got a divorce, got diagnosed with an illness, got a new job). (If symptoms last 6 months or more, however, we call it GAD or generalized anxiety disorder).
Note that it is a diagnosis of exclusion. In other words, if the patient is depressed after getting a new job and meets the criteria for MDD (major depressive disorder), they have MDD NOT adjustment disorder! If they don’t meet the criteria for anything (less severe depression/ anxiety following a life event) we can then call it adjustment disorder.
Patient has little energy and feels hopeless for 4 years. Diagnosis?
Persistent depressive disorder (dysthymia)
Remember, it’s called persistent if it goes on for more than 2 years
Criteria for diagnosing persistent depressive disorder (dysthymia)?
Milder depression (sometimes only 2 depressed symptoms) lasting MORE THAN 2 YEARS (no more than 2 months w/o depressive symptoms).
Girl cuts her celery in the same sized pieces before eating. Eats very little. Brushes her hair 21 times per side and brushes teeth for exactly 11 minutes each morning. Feels like she has to or something will happen to her. Diagnosis?
OCD (obsessive compulsive disorder)
(Note these people do rituals/ routines that are unproductive but they feel like they have to or something bad will happen)
What is the best step for preventing suicide completion?
Making sure firearms are not available to the patient (patients are far more likely to COMPLETE suicide if a gun is available in their home vs. having to find one and having time to get in a better mental state/ change their mind about suicide by the time they do)
After the STEP 1 exam, you decided to stop thinking about it because “worrying won’t help.” What defense mechanism is this?
Suppression (voluntarily choosing to not think about something bc you can’t handle it)
*note: this is a “mature” defense, meaning it’s a healthy coping mechanism. Contrast this to Repression (involuntarily forgetting a memory bc you can’t handle it), which is NOT a mature defense (not a healthy coping mechanism).
What are the mature defense mechanisms? (Note: mature means it is a healthy coping mechanism/ not associated with harm)
“Mature adults wear a SASH”
SUBLIMATION (using negative emotions in a positive way like channeling anger toward step 1 into studying like a pro)
ALTRUISM (caring for others to decrease your own stress/ anxiety like helping a pre-med student with the application process to feel good about yourself during med school stress)
SUPPRESSION (choosing to not think about something like not thinking about step 1 until the test results come back bc it’s out of your control for the time being and you can’t handle the thought)
HUMOR (joking about the boards)

Old person has a UTI. Now presents with mental status changes, is confused and aggressive toward nurses. What’s going on? How do we treat this patient?
Delirium
Treat the underlying cause of the delirium (in this case, the UTI) plus treat with an anti-psychotic (to treat the agitation and make the patient sleepy and calm like sedative) if the patient is at risk for harming their self or others (such as in this case- the patient’s delirium has gotten so bad she is psychotic and aggressive to nurses).
What is delirium?
Brain inflammation—> mental status changes (after surgery, infection, while on certain drugs)
Old person gets a UTI, now has mental status changes (going in and out of normal thought and confusion/ agitation/ passing out). What is going on?
Delirium
Old person comes into your clinic complaining of memory loss. Forgetting to take medication, forgetting names of grandchildren, forgetting to turn off the stove…also says he feels worthless. Diagnosis?
Depression-related cognitive impairment
Always rule out depression in a person presenting with dementia-like symptoms! Treat the depression and the memory impairment should go away.
Patient is taking anti-psychotic medication. For step 1, what can you pretty much assume the patient has?
Schizophrenia
What medication do we give to patients with treatment-resistant schizophrenia (not responding to anti-psychotic medications) or schizophrenia with suicidal thoughts?
Clozapine
Not first line bc has nasty side effects- agranulocytosis, seizures, myocarditis, and metabolic syndrome
What antibiotic can cause Serotonin syndrome if taken concurrently with a Serotonin increasing medication (like an SSRI)?
Linezolid
It acts like a MAO inhibitor (meaning it blocks the MAO enzyme that normally breaks down serotonin before its re-uptake by the pre-synaptic neuron—> no breakdown of serotonin means more serotonin at the synaptic cleft)
If you’re already on an SSRI (blocking serotonin re-uptake—> increasing serotonin at the synaptic cleft), another med that also leads to more serotonin can lead to TOO MUCH serotonin= serotonin syndrome (life-threatening).
Guy is depressed and one time while depressed, also heard a voice telling him he doesn’t deserve to live. Diagnosis?
Major depression with psychotic features
The psychosis is occurring during the depression
Person is hearing voices, having delusions. What’s this called?
Psychosis
What’s psychosis?
Hearing voices, having delusions
Do you hear voices in Bipolar disorder?
No. They are “on top of the world” like walking around naked at night, not sleeping for 2 weeks and not tired, spending all their money, calling the president bc they think the president will talk to them bc they’re so important…but not hearing voices/ having psychosis.
Highly functioning person but has weird thought like my neighbor is out to steal all my stuff (even though the neighbor is perfectly normal). Diagnosis?
Delusional disorder
How do you diagnose MDD (major depressive disorder) with psychotic features?
Patient meets criteria for depression (episodes of depression lasting at least 2 weeks with at least 5 out of the 9 SIG E CAPS depression symptoms) AND has psychosis (delusions and/ or hallucinations) WITH the depression (psychosis is never occurring on its own/ in the absence of depression).
Patient was diagnosed with schizophrenia and started on anti-psychotic therapy. Comes back a few weeks later complaining of being anxious and you observe the patient is fighting and unable to stay in the same position. What’s going on?
Akathisa (restlessness and inability to remain in 1 position)= extrapyramidal side effect of anti-psychotic medication.
(Fix this problem by decreasing the dose of her medication, or supplement with a beta-blocker.)
What is Akathisia?
Restlessness, inability to stay in 1 position
An extrapyramidal side effect of anti-psychotic medications (if dose is too high for the patient)
Best drugs to treat alcohol withdrawal? Give drug class and 2 specific drug names.
Benzodiazepines
1. Diazepam
2. Chlordizepoxide
(The long-acting benzo’s that allow for smooth withdrawal/ taping off the drug)
Chlordiazepoxide. What class of drugs does it belong to? Use to treat what?
Benzo’s (note: most benzodiazepines end in “-Pam” but this is an exception)
This is a long-acting Benzo used to treat alcoholic withdrawal (allows for smooth tapering off drug)
Why are benzo’s useful in treating alcohol withdrawal (explain the mechanism)?
Both benzodiazepines and alcohol bind to GABA-A receptors (they enhance GABA inhibitory/ CNS depressant effects, but bind to different sites on the GABA-A receptors). So, if an alcoholic quits alcohol and gets put on a Benzo, the Benzo will take the place of the alcohol in binding to the GABA receptor to avoid withdrawal symptoms and the patient will slowly get tapered off the drug.
Patient had a good friend die of pancreatic cancer. Now is worried she may have it, even though she has zero symptoms and all tests are normal. Psych diagnosis?
Illness anxiety disorder (aka hypochondriasis)
What’s somatic symptom disorder?
They have a symptom (ex: minor abdominal pain) and they are convinced it’s something crazy that it is not (ex: pancreatic cancer).
Illness anxiety disorder VS. somatic symptom disorder?
Illness anxiety disorder (aka hypochondriasis)—> no symptoms, yet convinced they have something (ex: perfectly healthy but sure they have pancreatic cancer)
Somatic symptom disorder—> have a symptom, but convince they have something it’s not (ex: minor abdominal pain but sure it is pancreatic cancer)
What is facctitious disorder imposed on self aka Munchausen syndrome?
Patient fakes illness because they like playing the “sick role” and getting medical attention
Menchausen syndrome (Factitious disorder imposed on self) vs. Menchausen syndrome by proxy (Factitious disorder imposed on others)?
Menchausen—> pretend to be sick (or make self sick) a lot bc like playing “sick role” and getting medical attention
Menchausen by proxy—> pretends their kid or elder is sick (or makes them sick) to get medical attention
Mechanism of SSRIs?
(SSRI= selective serotonin reuptake inhibitor)
Block the serotonin transporters (on the pre-synaptic cleft to prevent re-uptake and thus increase serotonin in the synaptic cleft)
(*note: SSRIs do NOT block serotonin receptors on the post-synaptic side)
What are Schizoid people like?
They like to be alone, more comfortable that way (a cluster A “weird” personality disorder)
“SchizOID like to avOID people”
Schizoid vs. Schizotypal? What personality cluster do both these fall under and what’s the difference between them?

Borderline- unstable mood and relationships, splitting (see things/ people as all good or all evil), fear of abandonment, can be suicidal, self-mutilation, emotional emptiness (“Borderline”)
Histrionic- attention-seeking, dramatic, sexually provocative (“flamBoyant”)
Narcissistic- sense of entitlement, lacks empathy, thinks they’re the best, doesn’t respond well to criticism (“Best”)
Avoidant, obsessive-compulsive, and dependent belong to what cluster of personality disorders? Explain what they mean.
Cluster C (“Worried”)
Avoidant- afraid of rejection, avoid people bc worried people won’t like them, hypersensitive to rejection and criticism (“lonely and longing”- they want relationships but too afraid they are inadequate)
Obsessive-compulsive personality disorder- loves to-do lists, always needs a plan, perfectionist, OCD-type of behaviors however, they are productive/ all helping to achieve a goal
Dependent- excessive need for support, low self-confidence, often stuck in abusive relationships
Woman believes to have magical powers. Her jewelry predicts the future. She has few friends. Diagnosis?
Schizotypal personality disorder (cluster A- “weird”)
*note: don’t confuse with another disorder based on her having no friends—her weird behaviors are leading to her having no friends
Lady dreams about getting married but is single. Eats lunch alone everyday bc she fears her co-workers will not like her personality and sense of humor. Avoids people. Personality disorder?
Avoidant personality disorder (cluster C- “worried”)
“Lonely and longing”-wants relationships but think they are inadequate/ people won’t like them
Jen is ready to die and to have a chance at saving her, you’d need to intubate. The advanced directive states Jen does not want intubation, however the family insists that she wrote this a long time ago and her grandchild was just born that she’d want to meet…they are sure her wishes as of today would be to permit life-saving procedures. What do you do?
Do not intubate. You must always follow the advanced directive (if there is one).
A patient was feeling down, no interest in activities she usually enjoyed, lack of appetite, etc. She was started on treatment. A few weeks later, she is brought in by a loved one to be seen bc she went 3 days without sleeping and does not feel tired and spent a huge sum of money to purchase plane tickets so she could travel the world to promote world peace. What happened?
She initially presented with depression symptoms only and was given an SSRI. But she really had Bipolar (make sure to screen for this in depressed patients before starting them on an SSRI by asking if they’ve ever had a time in their life where they feel on top of the world/ go days without sleeping/ do irrational things). So the SSRI triggered a manic episode! (SSRIs are contraindicated in bipolar patients for this reasons…think of it as they make sad people happy and too much happy for a bipolar patient—> mania. They need mood stabilizers instead.)
Fluoxetine, Paroxetine, Sertraline, and Citalopram all belong to what class of drugs?
SSRIs (selective-serotonin re-uptake inhibitors)
Fluoxetine (Sketchy: “fly out” banner)

Earliest age we can diagnose ADHD?
4 or 5 years (cannot diagnose before that bc normal toddler behavior is “ADHD” like)
3 year old boy is unable to dress himself or wipe himself. He is disruptive in his preschool class and constantly gets out of his chair to move around. What’s going on?
Nothing- this is normal development. Children are not expected to be fully potty trained and capable of dressing themselves until age 5. Also, ADHD is not even considered as a diagnosis until age 4-5 because normal toddler behavior is low attention span.
Girl seemed to develop normally as a baby. Now she’s a little over 1 year old and wringing her hands (twists them together until they are red, dry, and painful). She is unable to sit up without support/ being held up. Her head circumference has decreased. Diagnosis?

Diagnosis?
Autism (ASD)
-poor social interactions, communication problems, repetitive behaviors (need sameness), may have intellectual disability and unusual gifts/ abilities (savants), more common in boys and usually presents early childhood
A teen girl binge eats and forces herself to vomit. Her BMI is 17.5. Diagnosis?
Anorexia nervosa (binge eating/ purging type)
*remember, the diagnosis of anorexia vs. bulimia is based on BMI. If < 18.5–> anorexia, NOT bulimia
A patient has generalized anxiety disorder (GAD), but wants a drug that gets out of her system quickly so she’s clear-headed for work the next day. What should you prescribe?
Benzodiazepine (1st line= SSRIs, but Benzos are good for short-term anxiety treatment and kick in/ get out of the system faster)
Diagnostic criteria for manic episode?
3 or more of the “DIG FAST” symptoms:
Distractibility
Impulsivity (do crazy things like spend all their money w/o thinking of the consequences)
Grandiosity (inflated self-esteem, think they can do anything)

*remember “at night BATS Drink Blood”—B (beta), A (alpha), T (theta), S (sleep spindles and K complexes), D (delta), B (beta)
Generalized anxiety disorder vs. panic disorder?
Generalized anxiety disorder (GAD)- excessive worry for at least 6 mo about multiple issues
Panic disorder- multiple panic attacks with physical symptoms, anxious thought is more specific, sometimes no obvious trigger
Conduct disorder vs. oppositional defiance disorder?
Oppositional defiance disorder- kids not respecting authority
Conduct disorder- kids showing aggression toward people/ animals, committing crime like theft, destruction of property (more severe violations of the basic rights of others)

Adjustment disorder (anxiety/ depression within 3 mo of a stressor and does not meet the criteria for another disorder like MDD or GAD)
What is acute stress disorder?
Like PTSD, but only lasting between 3 days- 1 month (flashbacks following a traumatic life event)
A guy with treatment-resistant depression presents with a BP of 200/100, tachycardia, tremor, and sweats. He recently ate meat, cheese, and drank some beer with his friends. What med was he likely on and what is going on?
MAO inhibitor
Tyramine consumption—> hypertensive crisis
Remember that MAO inhibitors block the breakdown of monoamines (serotonin, NE, dopamine) by MAO (the point is to increase serotonin at the synaptic cleft—> make the depressed person happy). BUT, they also block the breakdown of Tyramine (in meats, cheeses, and beer), so consumption of Tyamine on a MAO inhibitor—> build up of Tyramine, which enters systemic circulation—> HTN crisis (note this is why MAO inhibitors are rarely used for depression treatment— serotonin syndrome and Tyramine HTN crisis are bad side effects, so use only in treatment-resistant depression.)
Amitriptyline belongs to what class of meds?
Tricyclic antidepressants
Sketchy: tripping
Nortriptyline belongs to what class of meds?
Tricyclic antidepressants
Sketchy: tripping
Imipramine belongs to what class of meds?
Tricyclic antidepressants (Sketchy: imprint on face)
Imipramine, Amitriptyline, and Nortriptyline belong to what class of meds?
Tricyclic Antidepressants (Sketchy: “I want to ride my tricycle” recess scene. Imipramine= imprint on face. Amitriptyline and Nortriptyline= tripping.)
Anti-muscurinic symptoms include dry mouth, constipation, blurred vision, urinary retention, confusion, inc HR, dilated pupils, dec sweat, inc temp. Explain how I can think about these symptoms.
Anti-muscurinic means the muscurinic (parasympathetic) receptors are blocked. So, you’d expect to see sympathetic (fight or flight) symptoms.
Dry mouth—> you aren’t producing saliva when running from a bear (you produce it when resting and DIGESTING)
Constipation—> no time to poop when running from a bear
Urinary retention—> no time to pee when running from a bear
Confusion—> ?
Inc HR—> heart beats faster when running from a bear
Dilated pupils—> gotta let in more light to see better when running from a bear
Dec sweat—> this is opposite of what you’d expect…bc sweat glands have muscurinic receptors, even though sweat is a sympathetic function
Inc temp—> body heats up from the energy/ ATP spike while running from a bear
What type of drug is Buspirone? How long to take effect? Any big side effects?
Non-benzodiazepine anxiolytic (but not in Sketchy)
Used to treat GAD (Generalized Anxiety Disorder)
Takes 1-2 weeks to work
No major side effects—does NOT cause sedation, addiction, or tolerance and does not interact with alcohol.
4 mood stabilizers we can give to Bipolar patients?
- Lithium (stabilizing chair LIFT)
- Valproate (winter festiVAL)
- Carbamazepine (classic CAR carving)
- Lamotrigine (Llama)
(Remember the Lithium “Ski Mania” sketch in Sketchy)
Is it ok to give Sertraline, Paroxetine, Fluoxetine, or Citalopram to a Bipolar patient?
NO! These are all SSRIs, which can trigger a manic episode in a bipolar individual (think of it as: SSRIs take the sad patient and make them happy. They are capable of taking the bipolar patient and making them too happy= mania)
What general class of drugs do you typically use to treat a Schizophrenia?
Anti-psychotics
What general class of drugs do you typically use to treat a Bipolar patient?
Mood stabilizers
Diagnostic criteria for Schizophrenia?
At least 2 of the following symptoms (with at least 1 being from symptom #1-3):
1. Delusions
2. Hallucinations
3. Disorganized speech
4. Disorganized behavior
5. Negative symptoms (flat affect, apathy, anhedonia/ can’t feel pleasure, alogia/ poverty of speech, social withdrawal)
Has to have been going on for at least 6 months with at least 1 month of continuous symptoms
Most common type of hallucination in schizophrenic patients?
Auditory hallucinations (hear voices) (Olfactory and tactile hallucinations, where patients smell or feel things, are seen more in substance abuse and other neurological problems)
What are positive and negative and cognitive symptoms of Schizophrenia?
POSITIVE- hallucinations, delusions, unusual thought processes, disorganized speech, bizarre behavior
NEGATIVE- flat or blunted affect, apathy, anhedonia (can’t feel pleasure), alogia (poverty of speech), social withdrawal
COGNITIVE- reduced ability to understand or make plans, dec working memory, inattention
How should somatic symptom disorder be managed?
Have regularly scheduled doctor visits with the SAME doctor (avoid referrals and unnecessary testing)
*remember somatic symptom disorder is when a patient has a symptom and is convinced it’s something that it’s not (ex: tummy ache and believes he/ she must have pancreatic cancer, despite normal test results)
What are the earliest symptoms of alcohol withdrawal (8-12 hrs hours since last drink)?
Insomnia, tremor (“the shakes”), anxiety, autonomic hyperactivity like inc BP and HR
What are the symptoms of alcohol withdrawal: (1) 8-12 hrs hours since last drink, (2) 12-48 hrs since last drink, and (3) 48-96 hrs since last drink?
8-12 hrs—> Insomnia, tremor (“the shakes”), anxiety, autonomic hyperactivity like inc BP and HR
12-48 hrs—> seizures
48-96 hrs—> delirium tremors (DT) (fever, disorientation, severe agitation)
When do children usually understand that death is permanent?
Age 7 (Before this, kiddos may think the dead person will magically come back to life and they may also think the grief of others is their fault. This is NOT a “complicated grief reaction”, but is “age-appropriate behavior.”)
What is depersonalization/ derealization disorder?
Feelings of detachments…feeling like you’re watching yourself/ outside of your own body
What is dissociative amnesia?
Inability to recall important personal information following trauma/ stress (but usually reversible).
What is dissociative identity disorder? What is it also known as?
When a person takes on 2 or more distinct identities/ personality states
(Associated with sexual abuse, PTSD, depression, substance abuse, borderline personality, and somatoform conditions)
aka MULTIPLE PERSONALITY DISORDER
Depression + days of feeling overly optimistic, juggling multiple jobs, feeling great despite only 3 or so hours of sleep. Diagnosis?
Bipolar II
Note: these are hypOmanic episodes, not full-on manic episodes, so bipolar II not I. Mania (bipolar I) would involve more severe symptoms…the person would not be able to work jobs but would engage in meaningless “work” running around naked thinking they’re king of the world type of behavior.
Feeling anxious lately, sweaty, palpitations, losing weight w/o trying. Diagnosis?
Hyperthyroidism (this is seeming to involve more systemic symptoms, not just generalized anxiety disorder where you lose weight w/o trying…if you lost weight from anxiety it’d be due to a change in appetite from stress, not you kept up with your normal eating routine and just noticed you’re shedding pounds).
Selegiline, Tranylcypromine, Phenelzine, and Isocarboxazid belong to what class of drugs?
MAO inhibitors (Sketchy: Selegiline= sledge hammer, Tranylcypromine= “try a sip of wine,” Phenelzine= funnel, Isocarboxazid= boxed wine)
What class of drugs does it belong to? Selegiline.
MAO inhibitor (sledge hammer in Sketchy)
What class of drugs does it belong to? Tranylcypromine.

Flumazenil (fluffy dog wearing a muzzle in Sketchy. It is a competitive antagonist at benzo receptor site)
What is the safest drug to give an elderly patient needing pharmacological treatment for insomnia?
Ramelton (Sketchy: “Melt Away” sign for Melatonin and Ramelton= melatonin receptor agonist)
Are benzos safe to give to elderly patients?
No, not the best idea. They are more prone to symptoms such as confusion, falls, delirium, disorientation…
Difference between classical and operant conditioning?
Classical conditioning- learning by associating a stimulus with something (ex: Palvot’s dogs became conditioned to think the bell meant food).
Operant conditioning- learning by punishment/ rewards.
What’s the pharmacological treatment for narcolepsy (if good sleep hygiene doesn’t do the trick)?
Daytime stimulants: amphetamines or Modafinil
And/or nighttime sodium oxybate (GHB)
