Personality Disorders (II).

Now that we know how personality disorders are defined, we can discuss specific types of personality disorders.

DSM-4 divides personality disorders into three “clusters”: A, B, and C. These clusters are based on “descriptive similarities”. The authors make an important comment:

It should be noted that this clustering system, although useful in some research and educational situations, has serious limitations and has not been consistently validated.

This means that these “clusters” can be useful in theory, but may be irrelevant, illogical, and a bunch of hooey in application.

Furthermore, DSM comments:

… individuals frequently present with co-occurring Personality Disorders from different clusters.

(The world of cookies would be easier to understand if there were only butter, fruit, and nut cookies, but sometimes you end up with a platter of apricot and pistachio cookies, hamantash cookies, and shortbread and chocolate chip cookies.)

The language used to describe the clusters of personality disorders (and the personality disorders themselves) can be interpreted as criticism. Instead of recognizing the clustering system as a heuristic, people might overlook its “serious limitations” and assume that the clustering system provides definitions.

This can lead to the unfortunate practice of people saying things like, “He’s definitely personality disordered,” or “She’s such a borderline,” when, in fact, no personality disorder is present and people actually mean, “I’m getting so annoyed with that person”.[1. You feel what you feel. Own it. That will make you a more effective clinician. If you don’t acknowledge your own emotions, they will come out in some other way that might affect your behavior in ways you don’t like.]

You can see how this starts upon reading how most medical students learn about the three clusters of personality disorders:

“Here’s a mnemonic for the personality disorders. Remember the three ‘W’s: Weird, Wacky, and Worried. Cluster A is ‘weird’, cluster B is ‘wacky’, and cluster C is ‘worried’. That’ll help you keep the personality disorders straight on your shelf exam.”

So, after that entire preamble, here are the verbatim DSM definitions of the three clusters of personality disorders:

Cluster A includes the Paranoid, Schizoid, and Schizotypal Personality Disorders. Individuals with these disorders often appear odd or eccentric.

That’s where the “weird” comes from.

Cluster B includes the Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorders. Individuals with these disorders often appear dramatic, emotional, or erratic.

And that’s where the “wacky” comes from.

Individuals with “cluster B traits” or personality disorders within this cluster most commonly come to clinical attention because their behaviors often cause distress both to themselves and those around them.

Cluster C includes the Avoidant, Dependent, and Obsessive-Compulsive Personality Disorders. Individuals with these disorders often appear anxious or fearful.

And there’s “worried”.

I’m not a linguist, but it is easy to see here how the use of language can greatly affect the way we think about events, behavior, people, etc. When we distill personality disorders down to single words, we forget the other criteria for personality disorders (the “enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture, is pervasive and inflexible, has an onset in adolescence or early adulthood, is stable over time, and leads to distress or impairment”).

That mental shortcut can significantly affect how we treat patients with these conditions. This is why I try to remain vigilant in what words I use to describe patients both to myself and others.

Next: We’ll start going through the specific personality disorders and interesting data associated with them as I review the literature.

Personality Disorders (I).

I’ve been asked to give a talk about personality disorders.[1. Writing about personality disorders here, I hope, will help me organize my talk and post more frequently.]

It’s akin to being asked to give a talk about cookies. (Do I discuss the distinctions between bar, drop, and sandwich cookies? Do people want to hear about the varieties of butter, fruit, and nut cookies? Should I compare cookies with other confections? What about the term “biscuit”?)

I suspect that part of the reason why I find the breadth of the subject daunting is because I’ve never given a talk on personality disorders. (I also prefer teaching certain topics, such as schizophrenia and suicide risk assessment. My training in dialectical behavior therapy (DBT), though, has helped me craft talks about difficult interactions with clinical settings and borderline personality disorder. DBT has also significantly influenced my clinical practice; I am grateful for the opportunity to learn about this early in my training.)

DSM-4[2. Yes, DSM-5 is now out—I am already behind.] provides the following criteria to define a personality disorder:

A. An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture.

Personality disorders account for culture. This is why, in the United States, it is not considered aberrant when someone goes to church every Sunday because he believes that a crucified man was resurrected from the dead after three days in a tomb.

This pattern is manifested in two (or more) of the following areas:

Someone once commented that these diagnostic criteria are something like “ordering from a Chinese menu”. (No comment.)

(1) cognition (i.e., ways of perceiving and interpreting self, other people, and events)

“Cognition” can be summarized as “thoughts”.

(2) affectivity (i.e., the range, intensity, lability, and appropriateness of emotional response)

“Affectivity” can be summarized as “emotions”.

(3) interpersonal functioning

This refers to relationships (both “deep” and “not so deep”).

(4) impulse control

… or, “What someone does when they feel an urge: can he sit with it? does she feel compelled to react immediately? if she does react, what is the reaction?”

To be clear, just because someone waits a while before demonstrating a reaction to an event does not necessarily mean that his impulse control is “good” (consider someone who reacts by planning and then executing a murder).

B. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations.

This is how one of my teachers impressed this criterion upon me: Most of us have all of the personality disorders, not just one of them. This means that we have a variety of ways (thoughts and behaviors) of coping with stress. This suggests healthy coping.

If, for example, I hear bad news, I might go for a walk, spend time with friends, or eat a sack of cookies.

If my sole coping skill consisted of eating sacks of cookies at home, at work, with friends, and by myself, that could suggest an inflexible and pervasive pattern.

C. The enduring pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning.

The act of eating sacks of cookies probably won’t get me into too much trouble. If, however, I only talked about cookies, kept five sacks of cookies underneath my pillow “just in case”, insisted that my employer pay me in sacks of cookies, and refused to go out with my friends unless they took me to a bakery, that would probably lead to “significant impairment” in multiple areas of my life.

D. The pattern is stable and of long duration, and its onset can be traced back at least to adolescence or early adulthood.

This is why we generally avoid a diagnosis of a personality disorder until someone is at least 18 years old, though brain “maturity” may not actually occur until someone is closer to age 25.

Some psychiatrists insist that they can diagnose a personality disorder after meeting someone once. I disagree.

E. The enduring pattern is not better accounted for as a manifestation or consequence of another mental disorder.

If someone’s thoughts and behaviors are most consistent with a diagnosis of schizophrenia, then diagnoses of schizoid, paranoid, and schizotypal personality disorders do not apply.

F. The enduring pattern is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., head trauma).

A psychiatrist’s primary job is to rule out medical causes of a condition that appears psychiatric. (That is often easier said than done.)

If that is the general definition of a personality disorder, what about specific personality disorders? Should I discuss personality disorders discussed in ICD-10? What about the personality disorders described in previous editions of the DSM? (Only four have been present across all four editions of the DSM.) Where is the balance between theory (what the conditions are) and application (the function of the behaviors and how to work with people who have these conditions)?

When I Grow Up…

When I grow up, I want to be a drunk.

I want to wake up feeling restless and uncomfortable. It’ll be neat to drag myself out of bed to open that first bottle of wine. I’ll drink all of it within an hour. Then I’ll go to the liquor store. The guy behind the counter will know that, everyday, I will buy a pint of vodka from him. He will look at me with stony eyes, which will make me feel even more restless and uncomfortable. What he doesn’t know is that I will also get two more bottles of wine and a case of beer from the grocery store before I return home. As an adult, I want my sole coping skill to consist of getting drunk.

When I grow up, I want to get fired from all of my jobs because I am frequently drunk. I can’t wait for my boss to call me into his office because my coworkers smell alcohol on my breath. It’ll be fun to make an a$$ of myself while working because I just can’t stop myself from drinking that bottle of wine in the morning.

When I grow up, I want strangers to see me doubled over a tree planter with vomit on my shirt. I look forward to police officers shouting at me to get the f-ck up and move along. I am eager to see the disdain and disgust of the firemen and paramedics when they realize that the 911 call was, yet again, for me. I can’t wait to hear the doctors and nurses in the emergency rooms say things like, “Oh, not him again. I’m so tired of seeing him. He’s taking up a bed that could be used for someone who is really having an emergency.”

When I grow up, I want to ruin all of my relationships because I am a drunk. I look forward to destroying property and scaring my girlfriends. I can’t wait for my wife to request a restraining order against me because I’ve threatened to kill her one too many times. It’ll be great when my parents and siblings never invite me over to their houses because they think my behavior is out of control. I can’t wait to achieve that level of isolation and notoriety.

When I grow up, I want to spend a lot of time in jail. I look forward to receiving charges of public intoxication, disorderly conduct, assault, and battery. I can’t wait to collect warrants because I was too drunk to show up for my court dates. It’ll be fun to bounce in and out of jail and frequently apologize to of all of my probation officers. It’ll be neat to lose my housing because I couldn’t pay my rent while I was in jail. Homelessness will be a delight!

When I grow up, I want people to judge me because of my alcohol problem. I look forward to people hating me because they believe that I choose to drink alcohol to the point that I can’t function. It’ll be exciting to realize that people believe I am useless and a waste of a human being.

When I grow up, I want to hate myself because I am a drunk. It’ll be fun to feel constant shame and complete lack of control over myself or anything else. I can’t wait to experience unending self-loathing and disappointment. And how thrilled I will feel when I realize that the only thing that makes me feel better in the moment is drinking more alcohol.

CPR and Informed Consent.

Radiolab recently aired a show called “The Bitter End” that discusses the end-of-life care preferences of physicians and non-physicians. Physicians are much more likely to decline “heroic” measures, such as CPR, mechanical ventilation, feeding tubes, etc. This comes as a surprise to the hosts and, presumably, to other non-physicians. It’s a good show. I recommend it. (Full disclosure: I like Radiolab.)

In the show, Ken Murray argues that physicians decline these “heroic” measures for intellectual reasons. He argues that we know the data, which includes a study that reported that, of people who receive CPR, only 8% are successfully resuscitated. (Of those 8%, only a portion of them return to their full previous function.)

I don’t think physicians decline CPR and other “heroic” measures because of evidence-based, numerical data alone.

The experience of performing CPR and attending to patients who are critically ill contribute to physician preferences against CPR. It’s emotionally taxing. All physicians have seen the trauma we cause with these “heroic” measures. Yes, performing CPR can lead to cracked ribs and punctured lungs. Mechanical ventilation can lead to severe cases of hospital-acquired pneumonia. Intravenous hydration can cause massive tissue swelling. The consequences of heroic measures are often devastating.

Physicians are taught “first, do no harm.” Sometimes, these heroic interventions seem like they cause more harm than good.

Perhaps physicians decline CPR and other “heroic” measures because of anecdotal experiences and emotions. This isn’t randomized, placebo-controlled data. However, anecdotal experiences and emotions are still data.

Furthermore, there is no true “informed consent” with CPR. When patients are able to consent to CPR, they are not truly informed. They cannot fully appreciate and understand what CPR entails because they have never experienced it.

By the time patients are truly informed about CPR—when someone is pushing on their chests, when a second person is manually inflating their lungs, when a third is injecting medications into their blood, when a fourth is trying to stick a breathing tube down their throats—they are unconscious. They cannot offer or withhold consent.

(This is true with many things in medicine: No one can give true informed consent for general anesthesia, surgery, or even medications. We often only know all the information after the fact. Patients often give consent based on hope and faith.)

Physicians see and treat patients who have undergone CPR. Those patients are usually paralyzed, swollen with fluid, and unconscious. Upon witnessing that, physicians might wonder what the differences are between “living” and “existing”.

This could explain why their end-of-life care preferences differ from that of the general public.

Daily Schedule: Assertive Community Treatment.

A sample agenda as the consulting psychiatrist with an assertive community treatment (ACT) team:

7:55am. No one is at the office yet. Insert a key into the gate in front of the building. The gate makes grating and squeaking sounds as it rolls up. After entering the building, quickly disable the alarm, lock the door on the way in, and roll the gate back down. From the medication room, pack into a brown paper bag a pair of gloves, two alcohol pads, one band-aid, a pinch of 2×2 gauzes, a portable sharps disposal container, and a pocket-sized bottle of hand sanitizer. Unlock a different cabinet and fish out a small box that contains liquid haloperidol decanoate, a long-acting antipsychotic medication. Drop that into the brown paper bag.

Leave the office, secure the building, and make sure that the gate is rolled completely down before walking away.

8:40am. Arrive at a patient’s[1. All patients described here are composites of people I have seen across time.] apartment uptown. She lives with her mother, grandmother, and her mother’s boyfriend. As usual, she’s still sleeping, even though she knew that this visit would occur around 8:45am. She’s wearing a strappy tank top and baggy pajama pants. She rubs the sleep form her eyes. She walks back into her bedroom. An electronic rose is in the corner next to her mirror. Different colored lipsticks are on the table. There is a desk lamp on the nightstand, as well as several magazines.

She shrugs her shoulders after realizing that her offer of a seat on the unmade bed was politely declined. She’s doing pretty well: She’s re-enrolled in GED classes and is studying to take the test, though she’s finding the math portions difficult. She’s still going to the local bar on weekends, but denies getting drunk. When she also denies smoking marijuana, her response seems honest, though her next visit to the office will include a urine drug screen test. The antipsychotic medication isn’t causing side effects. She asks for advice on how to avoid bad boyfriends.

9:30am. Arrive at the second patient’s apartment after a subway ride further uptown. He lives with his elderly parents. He’s not doing well. He yells at his mother and his father often locks himself in the bedroom so they don’t have to interact.

He begins to share that he is dating a woman, then suddenly comments that he hasn’t drank any alcohol in months. His mother interjects and says that he has come home very late at night smelling of alcohol. The stories from the past week spill from her mouth; she’s watched him cross and re-cross the same street for two consecutive hours. Sometimes he yells about the gods who have failed him. Small items—vases, salt and pepper shakers, silverware—have started to go missing from the apartment.

He says he’s taking his medications, but his mother says that she finds pills in the trash cans. He mumbles under his breath.

No, she hasn’t had to nor wanted to call the police. No, he doesn’t want to go to the hospital. He’s eating the ham and cheese sandwich that she’s made for him. She asks what will happen next.

“If you feel unsafe, call 911 and call the ACT team. Don’t wait. Just call. We’re all worried about him.”

He rolls his eyes and asks the wall why anyone would think he would hurt anyone. He doesn’t seem to remember that the last time he developed symptoms and drank alcohol, he punched his daughter.

10:40am. Arrive at the third patient’s apartment after a bus ride across town. He’s an elderly man who believes that his neighbors have stolen his internal organs and that cannibals will eat him if he leaves the building. These beliefs as well as gait problems keep him in his apartment. This is the person who will receive the haloperidol injection.

The usual conversation about his medication ensues. He’s willing to accept the medication, but wants to discuss again why it is at its current dose. The reasons haven’t changed from last month. He nods in what seems to be understanding, though then asks, “The medication will not make my skin turn blue, right?”

This is a significant improvement from a year ago.

Three large cockroaches skitter across the countertop. Two empty cartons of orange juice sit on the kitchen table. He looks into the living room, which holds his bed. He doesn’t go into the bedroom anymore. He still cries when he thinks about his dead wife.

He rolls up his sleeve and looks at his arm when he receives the injection.

“It never hurts when you do it.” He’s probably just being nice.

11:45am. Arrive back at the office. A patient sits on the curb, smoking a cigarette, while chatting up a cab driver. Everyone says hello to each other.

11:50am. Two of the social workers are in the office. They and the secretary all share events from the morning. One of the ACT patients may leave the hospital tomorrow. One of the social workers will escort him directly from the hospital back to the apartment if the hospital discharges the patient.

“I’ll visit your guy tomorrow morning,” the other social worker says, referring to the second patient who lives with his elderly parents. “We’ll check in with him every day this week.”

12:00pm. Work on documentation from the morning visits. Mindlessly eat lunch.

12:53pm. Fourth patient arrives for his 1pm appointment. He greets everyone with a warm smile.

He recently started volunteering at the library and teaches young children how to read. He rides his bicycle around Central Park to help keep his blood sugars under better control. His daughter is coming to visit for the holiday. He plans to cook salmon for dinner tonight. He’d rather have fried chicken.

“I’m scared to lower my medication, Doc,” he says. “I don’t want to end up at the hospital again. But if you think all this weight gain might be from the medicine, I guess we could try it—you said real slow, right?”

After some more discussion, he concludes, “No, let’s not change the medicine now. Lemme get through the holidays and then we’ll try. Real slow. Real slow.”

His wishes are honored without argument.

2:00pm. The fifth patient hasn’t arrived.

2:10pm. The fifth patient still hasn’t arrived. She’s more organized than people might initially believe, but she’s rarely punctual.

2:17pm. “Heya doc, how you doing, how you doing,” the fifth patient says, flopping down on the seat. She’s chewing on a popsicle stick. She’s tied the two ends of a necktie together and is wearing that around her neck like a necklace. Four other neckties are tied around her neck the same way. Ear phones cover her ears, but they’re not plugged into anything. Her striped socks are pulled over her baggy sweatpants.

“Heya doc, how you doing, how you doing, the vapor’s hot today, so hot. The icicles bring down the vapor, the vapor pulls the magnet and the poles spin, they spin, that’s what makes the Earth spin, the vapor around the Earth spins, too, spins like a record, so cool, so cool….”

She just finished her first week as the filing clerk for the drop-in center. The staff there said that she did good work and that she seems to like it, but she occasionally breaks out into song.

“Do you like your new job?”

“Yes, yes, but I want them to like my new job, too. I like the money, too, I can buy myself some new shoes, new blue shoes, new blue frue true krue shoes, so krue, so cruel, cruel world.”

On the way out, she flings the popsicle stick into the trashcan and belts out, “NEW YOOOOORK… CONCRETE JUNGLES WHERE DREAMS ARE MADE OF….”

3:05pm. Sixth patient arrives. He sits down and looks out the office window into the lobby. Everyone said hi to him as he walked in. He didn’t respond.

He doesn’t say anything in the room. He doesn’t make any eye contact. He examines his nails. He reties his shoelaces. He rolls up his pant legs. He strokes his beard. He fishes a half-smoked cigarette out of his pocket, then puts it back in.

“What’s going on? Is something wrong?”

He sighs and shakes his head. He gets up and doesn’t look up in acknowledgment when he hears entreaties to stay. As he walks out of the office, he finally says, “I’ll be back.”

3:20pm. Ask one of the social workers to follow the Tacit Man out of the building with hopes that they will have a conversation.

3:22pm. Watch from the lobby while the social worker and the Tacit Man talk. They’re actually speaking to each other.

3:25pm. The social worker walks back into the building and the Tacit Man walks across the street.

“Tacit Man is fine, just having a bad day,” the social worker says. “He’ll come back tomorrow to see you, same time.”

“Thank you!”

3:27pm. Call patients to remind them of meetings scheduled for tomorrow. Most of them answer their phones.

3:45pm. Resume documentation with occasional interruptions from other patients wandering into the office to say hello.

4:35pm. Coordinate plans with the social workers for tomorrow. Discuss medication changes, medication deliveries, and which patients need closer monitoring.

4:45pm. Leave the office. That same client who was sitting on the curb and smoking is still sitting on the curb and smoking. He waves hello. I wave back.
