Understanding BPD vs. Bipolar: Key Differences Explained

BPD, which stands for Borderline Personality Disorder, has significant areas of overlap with bipolar disorder. Both disorders implicate a breakdown in the emotion regulation areas of the brain. But what are the differences? Cross-sectionally, they’re sometimes quite difficult to tell apart. More differences emerge when looking longitudinally across time.

  1. Bipolar is episodic and predictable in the short term: episodes of mania and depression (and mixed episodes) come and go in a fairly predictable fashion. Some people have depression first and then fly into mania, while others start out with a manic episode and then crash into the depression. It’s roughly 50-50 between these patterns, but within individuals the pattern stays consistent. Which is to say, if you’re a mania first bipolar, you’ll most likely always be mania first.
  2. BPD breakdowns tend to be triggered by some situation the person has found themselves in. Their responses may be over-exaggerated but there is some kind of trigger. Bipolar episodes can also be triggered sometimes, but classically, bipolar episodes can occur with no trigger at all. They’re related to a sort of internal thermostat which is broken. Thus, time of year — and changes in sunlight, which affects this internal thermostat — can be triggers for bipolar disorder, and less likely for BPD.
  3. Psychosis is much more pronounced in bipolar disorder than in BPD. The classic euphoric mania with grandiose delusions come to mind; in bipolar disorder, psychosis is limited to mood episodes and is almost always mood-congruent. (Meaning, someone with classic euphoric mania might have grandiose delusions that they are a very important person or have special powers or abilities; meanwhile, someone in a mixed episode might hear muffled voices that make them feel very paranoid about who might be watching, and they see bugs crawling all over the walls. Okay, the mixed episode examples are psychotic features I have experienced myself.) BPD people may experience transient, stress-related psychosis, but they don’t hold onto it as strongly as bipolar people.
  4. Sleep and changes in sleep are arguably the most important symptoms for bipolar people. Not sleeping enough feeds into mania, while sleeping too much feeds into depression. The relationship between BPD and sleep is less clear. Lack of sleep may worsen emotion regulation challenges. People with BPD who don’t get enough sleep are likely to be irritable during the day.

Bipolar Disorder vs. Manic Depression: Importance of Lived Experience

You may have heard that Bipolar Disorder used to be known as Manic Depression. This was the case until 1980, with the advent of the DSM-III. The committee over at the APA who decides these things had three goals in mind when they changed the name:

  1. Reduce stigma — The APA saw that the term “manic depression” had become highly stigmatizing.
  2. Provide a more accurate and clinical description of the condition
  3. Reflect the alternating periods of mania and depression that characterize the disorder — more on these in a minute.

I want to clarify that while the APA laid out the missions above, they did not consult the community members who live with the condition. Many people, some of them high profile (like Kay Redfield Jamison) still prefer the term manic depression still today. To change the name of a disorder without extensive community feedback feels like a violation of autonomy for those of us who live with a severe mental illness.

But let’s address the three goals laid out by the APA with the publication of the DSM-III…

  1. Although it’s very likely true that the term “manic depression” had become highly stigmatized, it seems a bit odd to assume that the stigmatization of the disorder came from what we choose to call it, rather than stemming from the people who live with the condition. Case in point, today “bipolar” is highly stigmatized and used inappropriately for a number of reasons — to refer to indecisive weather patterns, people we don’t like, and a host of other things. It’s just as bad as manic depression ever was. Why? Well, maybe the problem wasn’t the term manic depression. The stigma was never attached to the term. The stigma is attached to those of us who live with the condition, regardless of what you choose to call it. No matter how many times you change the name of the disorder, that truth would never change.
  2. Many of us in the bipolar disorder/manic depression sphere actually feel that “manic depression” is much more descriptive of our lived experiences. “Bipolar” exemplifies a particular phenotype, one which is at least somewhat common among bipolar folks (and considered by some to be an archetypal presentation) but to the exclusion of others with more uncommon manifestations of the disorder. If we are to take “bipolar disorder” at face value, I am left to assume that there are two “poles” (opposites) which people oscillate between. However, this ignores the very real and unfortunately common experience of mixed episodes — when the two opposing states of “bipolar” are somehow happening both at the same time. How can they be opposite, when in fact they coexist so frequently?
  3. I don’t think most people who know little about “bipolar disorder” are thinking about its longitudinal dynamics. Many people still believe that bipolar disorder is about quick shifts in mood lasting only a few hours (although these types of episodes do happen in classic bipolar disorder, they are much more rare and occur in the context of other well-known symptoms) or that bipolar disorder is the same as “multiple personality disorder”.

As it turns out, I think manic depression is both more accurate (instead of positing that mania and depression are opposing forces, when in reality, they seem to be linked and can even occur simultaneously) and, in the end, probably less stigmatizing than “bipolar disorder”. This just highlights the importance of including community input (for example, from “bipolar” patients) when making decisions like this.

The Impact of Bipolar Disorder on Physical Health

Those of us with bipolar disorder can bear a heavy burden when it comes to co-occurring conditions, medication side effects, and we are at higher risk for many diseases. Some of these effects are ameliorated by efforts at early screening and detection. We hope (perhaps naively) to catch tardive dyskinesia before it becomes permanent and Stevens-Johnson Syndrome before it becomes fatal. Likewise, in the US we have a federal registry for clozapine patients that aims to detect agranulocytosis (destruction of white blood cells, which disables the immune system) with rigorous blood testing.

Other medications may take a more nefarious route to affecting our health. Lithium is able to cross membranes and take up residence inside your body’s cells, where it stubbornly resists removal by hemodialysis. Years down the road, it can lead to kidney failure, not to mention destroying your thyroid gland.

But there’s more than meets the eye to the interface of bipolar disorder in medical care.

Bipolar disorder is widely stigmatized by medical professionals

I once presented at the ER for an abscess the size of a tennis ball erupting from my thigh (a consequence of my then-undiagnosed hidradenitis). I showed the triage nurse; she documented it. Then she asked for my phone and my shoes.

“The psychiatrist is going to see you,” an aide informed me.

“What? Why? I have an abscess!”

They didn’t care to listen to me. Two hours later, a psychiatry resident showed up at my bedside. He took a look at my abscess.

“I don’t know why they sent you over here,” he said, sighing. Another two hours passed before a “medical” MD came to take a look and determine (within minutes) that we were going to drain my abscess. It was extremely painful. Surely, anyone would be a touch irritable or agitated in such circumstances. But I’ve been told that having bipolar disorder in my history was good enough reason to detain me, independent of any other facts. You know what that’s called: discrimination. I hadn’t complained of any suicidal planning or expressed a desire to be admitted. In my place, someone without those two words in their file — “bipolar disorder” — would have been seen by a medicine doctor hours earlier.

But, to be fair, it’s not just bipolar disorder that is stigmatized. I was once being detained in the psych area of the ER, when an aide mentioned to another aide that she had PTSD. I was in a fairly good mood, and I joked, “You’re one of us!”

“I’m nothing like you,” she said, frowning coldly. “PTSD is not a mental illness.”

I was taken aback by her confidence and we started to argue when the charge nurse walked in. We both told our side of the story and the charge nurse decided to move the aide to a different part of the ER. She did not look happy, let me tell you.

Bipolar disorder can affect how drugs work in your body

Whether from drug-drug interactions or simply unusual metabolism of certain medications, prescribing medicine for physical health reasons is a tricky business when you have bipolar disorder. The most commonplace medications can be problematic: antibiotics (can cause mania), ibuprofen or most other NSAIDs (interacts with lithium and can raise lithium levels to toxic, resulting in profuse vomiting — try telling that to an overworked nurse who thinks you’re seeking pain meds!), prednisone or other steroids (can cause mania), Sudafed (stimulant — may cause mania)… the list goes on.

This is what I’ve found with alternatives. This only represents my own experience and should not be taken as an endorsement of research in this area (probably because there isn’t much).

Antibiotics: Doxycycline should be avoided, but amoxicillin is okay.
Ibuprofen/NSAIDs: The exception to this rule is old-fashioned aspirin, which is safe if you’re on lithium!
Prednisone/steroids: Unfortunately I haven’t found an effective alternative. You just gotta play the odds. Being manic is better than being dead.
Sudafed: I recommend diphenhydramine (Benadryl) which is effective, safe for bipolar disorder, and cheap.

Having bipolar disorder can increase your odds of having another disease

Some diseases and risk factors for diseases, including metabolic syndrome, obesity, diabetes mellitus (type 2), and diabetes inspidus (if you’re on lithium) appear to clearly be linked to certain medications people might take to treat their bipolar disorder. But others are less clear. Headaches are associated with bipolar disorder, especially migraines and cluster headaches (less commonly chronic tension headaches). Genetic evidence has aligned to connect epilepsy and bipolar disorder (such as the SP4 gene, which was published about in September 2024) and this is concordant with the longstanding clinical observation that bipolar disorder often responds to cocktails including anticonvulsant medications such as Lamictal (lamotrigine), Depakote (valproate), even Topamax (topiramate). Large studies have also shown that people with bipolar disorder are more likely to develop Parkinson’s Disease, independently of cases that are likely drug-induced.

Surprisingly, when COVID-19 first swept the world, some research suggested that people with bipolar disorder were more likely to have a severe or life-threatening COVID-19 disease course even when controlling for factors such as obesity. Taken together with available evidence, this may lend support to the idea that alterations in the body’s inflammatory pathways may be causal to bipolar disorder. It has long been recognized that influenza infection can precipitate manic or psychotic episodes. In January 2018 I had the flu and I became preoccupied with the fact that I (definitely) had AIDS and I began writing long goodbye letters to my friends. Luckily, the flu was better in about 3 days.

Drugs (use, abuse, and misuse) cause problems

As I mentioned, certain medications can have severe side effects…
Neuroleptics (such as Haldol/haloperidol): Neuroleptic Malignant Syndrome, Tardive Dyskinesia, Movement Disorder
Atypical Antipsychotics (such as Zyprexa/olanzapine, Risperdal/risperidone, Abilify/aripiprazole, and clozapine): Agranulocytosis (Clozapine specifically); Akathisia and movement disorder (particularly Abilify and Vraylar)
Anticonvulsants: Stevens-Johnson Syndrome (especially lamotrigine — and keep in mind that risk for SJS increases whenever you start or stop taking the medication suddenly, and if you do this multiple times your risk climbs higher and higher)
Antidepressants and other serotonergic drugs, such as stimulants and street drugs like MDMA: Serotonin Syndrome

Bipolar people are famous for resisting taking medications that could help them, which can make the above side effects more likely. Not taking your meds can also make bipolar disorder worse, and make you more at risk for accidental deaths such as a car crash, while also making you more at risk for intentional death (suicide). Lithium has uniquely shown a capacity to lower the risk of suicide.

Not only that, but it will always be assumed that you are “drug seeking” especially when you try to explain the bit about why you’re too good for the ibuprofen that everyone else takes. But no fear, the nurse has your back and will get you some IV lorazepam (Ativan) while they process your discharge.


If Autism Isn’t a Mental Illness, What Is?

My name is Elliot. I’m an autistic psychologist with bipolar 1 disorder (and ADHD). I’ve been mentioned in passing [1] [2] in news articles about autistic autism researchers, but I prefer to keep on the science side of things. I usually only use Twitter for personal entertainment, sometimes biting my tongue as I weigh the pros and cons of engaging in autism discourse. I don’t entangle myself too deeply in advocacy work. For the most part, I keep my opinions on controversial things low-key no matter which side I am on. This post is a divergence from that tendency.

I have not uncommonly heard people object to classifying autism as a mental illness. It’s almost taken for granted that autism doesn’t fall under that umbrella. You may be surprised to know how people try to justify it if you actually ask them “Why isn’t it a mental illness?” Indeed, when pressed the most common responses are along the lines of:

  • “Autism is a neurodevelopmental disability” / “You’re born with autism”
  • “Autism isn’t an illness” / “Autism doesn’t need to be treated”
  • “Autistic people aren’t like *those* people”

The common element in all of these responses is a lack of understanding of what mental illness is and what mentally ill people experience. The question I want to ask back is this: If autism isn’t a mental illness, what is?

I’m not unsympathetic to the cause of not labeling people as having an “illness” because they’re neurodivergent, but why is it okay to do it to schizophrenic folks and not to autistic folks? There are plenty of mad people who don’t exactly view their diagnosis as an illness, although opinions in the psychiatric community are varied on this topic. Some consider diagnostic labels to be a prison, and others a gift. We sure live with plenty of labels.

Pharmaceutical drug labels.

Mental illness takes many forms. Some of them are quite properly classified as “neurodevelopmental disabilities” (including schizo spec, bipolar disorder, and ADHD — among possibly many others). The disorders I just mentioned are predominantly caused by genetics, and are therefore present at birth. The expression does change over time — but don’t autistic people have qualities that change as they grow and learn?

People refuse to acknowledge the close similarities between autism and schizophrenia (and other severe mental illness).

I’m going to flat-out recognize this: I think a lot of our community is biased. There are a lot of autistic people that are sanist, and they’ve been permitted to perpetuate misunderstanding.

My own therapist once tried to convince me after I admitted to experiencing delusions earlier in the week that I was merely referencing thoughts that were “overly rigid” as a result of my autism. My psychotic symptoms were being falsely attributed to my autism, and a lack of care was being given where care was needed.

And in the real world autistic people are at high risk of being mistaken for schizophrenic and taken to an ER for psych evaluation when they’re in distress. People can be treated horribly. But instead of stepping back and saying “Why do we treat mentally ill people horribly?” we’ve decided that allyship is not for us and we double down on “Autism isn’t a mental illness.” We cast non-autistic (and some autistic!) neurodivergent people as the Other.

To be quite honest, I think some autistic people are scared of crazy.

Perhaps they’re scared of people who may be erratic, hard to predict, or have dramatic emotional reactions.

Are there reasons to set autism apart from conditions we consider “mental illness”? I just don’t see the justification for viewing autism as so singularly unique from other conditions. It’s possible that, in the future, we could redefine and do away with the label of “mental illness” altogether. I’ll be interested to see how language evolves for neurodivergent folks. I hope even moreso that people in the autistic community approach the psychiatric community with an open mind, and not with fear or prejudice. I see hope for a future of cross-disability solidarity.


One bipolar person’s drug regimen

Currently, I take 8 medications for psychiatric reasons. I’ve also been on many others — including most of the atypical antipsychotics, several anticonvulsants, antidepressants, and more. These are my current drugs ranked in terms of how essential they are (if, for example, I could only get some of them, perhaps due to a catastrophe):

  1. Lithium — Big Pharma has yet to come up with something better. It could never be patented, it wasn’t paid for by anybody. It actually works. And it’s all-natural. But also, it sucks. Nature is brutal.
  2. Haldol — Indispensable, though I might be switching to Thorazine in the near future. I don’t picture myself living without an antipsychotic again. Typicals seem to work better for me than atypicals did, though I’ve notably NOT tried Risperdal (even though it’s a good fit for my symptoms) or clozapine. Both were considered, though.
  3. Ativan (lorazepam) — My symptoms tend to cluster around anxiety, insomnia, and irritability — maybe paranoia — all things helped by benzodiazepines. If it were not so problematic, I might have ranked it #2. It’s the best immediate symptom relief I can get aside from maybe sublingual Zyprexa (olanzapine).
  4. Adderall — I would never actually achieve anything in life without Adderall. That said, my need to do something with my life is inherently superseded by my need to be alive, which is why it ranks #4.
  5. Lamotrigine (Lamictal) — An anticonvulsant medication. It seems to be doing something, because I become depressed without it. Though I’m not exactly sure what it’s doing.
  6. Gabapentin — I’m supposed to be using it for anxiety to offset my lorazepam use. It’s also useful for severe headaches. I still feel the pain, but I kind of don’t care, like the pain just doesn’t command my attention.
  7. Clonidine — It’s a blood pressure med, but I’m using it for insomnia. I cycle through medications for insomnia because they all lose their effectiveness eventually. I haven’t been on clonidine before so I don’t know how long it will be useful for. Other drugs I’ve used for sleep: Trazodone, Remeron, Ativan, Seroquel (and other atypical antipsychotics)…
  8. Diphenhydramine (Benadryl) — An OTC drug! The original antihistamine. I take it as 50mg softgels (two of them, which is slightly more than the bottle indicates — consult your doctor). Sometimes works for sleep, not super reliable and fades quickly. Useful if I have a cold or flu because Sudafed is not the best choice for my wiring. Also potentially protective against Haldol-induced side effects. So overall, something I take regularly, but not every day.

Anyone want to share their regimen?


Dreams & Interpretations (part 1)

I didn’t used to have a lot of dreams. Over the past few years, I’ve starting having more, some of them very vivid and strange. In this series of blog posts I’m going to attempt to find common themes within these dreams. I’m not analyzing them in the psychoanalytic sense; I’m merely looking at the composition of the dream and how it relates to itself and my life.

Body Horror

Dream: I’m suddenly unable to talk or make any sounds. I try to cry for help, but no sound comes out. I open my mouth and feel a string coming out of it. Slowly, I pull the string, and realize that a tampon is lodged in my throat. I gag and continue pulling the string, and eventually the tampon comes out and blood gushes out of my throat. I wake up.


Interpretation: This is actually a recurring dream I’ve had, although I haven’t had it for quite some time. It’s probably the one of the most aggressively transgender dreams I’ve ever had.


Safety Checks

Dream: I wake up in the middle of the night in a hospital bed. Dark, shadowy figures appear in the little window of my door and then vanish. I wake up.

Interpretation: Another recurring dream, often at the end of other dreams, like the first one. This one I used to have after my discharge from South Oaks Hospital. I didn’t like it there, and this dream (a fairly accurate representation of nighttime safety checks) was the result of my stress.


Trust Issues

Dream: I wake up in my hospital room to an electronic jostling sound, like an InkJet printer, coming from the vent above my bed. I go to get my vitals taken and eat breakfast in the day room, mentioning to a nurse that there was this weird sound in my room. I retire back to my bed. Two people step into the room, wearing white coats, and I expect them to be doctors — but I don’t recognize them. One of them pins me to the bed and the other injects me with a strange liquid, which makes the world hazy. I realize that these people must be scientists and the InkJet printer sounds must be their machines. Their injection was supposed to make me lose my memories of it.


I wake up later in the day, with my memories still intact — the serum didn’t work. Thankful, I decide I better contact someone. I call my psychiatrist on the phone and tell her that alien scientists are on the ward. “There are?” she says. “How do you know they’re scientists?” The white coats, I tell her. She assures me she will get to the bottom of this, but as we hang up, I realize my mistake: the alien scientists will simply wipe her memory.


I walk back to my room, but am confronted by the scientists in their white coats; I run in the opposite direction only to be stopped at the double locked doors with their “AWOL RISK DO NOT OPEN” signs. I laugh. Since their injection didn’t work on me, they’ll have to kill me. “I guess being killed by aliens is a pretty cool way to die,” I say. Suddenly, a beam of white energy enters my body and comes out through my palm, striking one of the alien scientists. He crumples to the ground, and his body slowly changes, reverse-aging until he is merely a fetus on the ground.


Interpretation: It seems fairly evident that the “alien scientists” in their white coats and brandishing IM injections are a stand-in for psychiatrists. What complicates that, though, is the fact that when I am looking for someone I trust to call, the first person I think of is my psychiatrist. So, there seems to be a distinction between trustworthy and untrustworthy psychiatrists. The reverse aging beam seems odd until it is considered that at the height of my psychiatric crisis I was age regressed into the mind of a child (an older child, I’d say 10-12 years old). In a way, what I inflict on them was the same pain I’d experienced myself. This might be a metaphor for opening up to them.


I’m lucky to have my bipolar disorder

There are times that I’ve felt cursed by having ultra-rapid-cycling, somewhat-atypically-presenting bipolar 1 disorder. My mood episodes are short (sometimes as short as one day, although usually lasting a few days to a week) and they can be very intense. I also suffer from mixed episodes, which are agonizingly painful to experience, and at times I have had profound suicidality that has led to multiple suicide attempts — one of which left me in a coma for three days and nearly claimed my life. Doctors said I wasn’t going to make it. But I did.

During the worst of times I’ve wished to have “classic” bipolar disorder instead of my bipolar disorder. In truth, “classic” features may be relatively rare; but it conjures the idea of long, bleak depressions punctuated by shorter, but still somewhat long, grandiose and euphoric manias. Separate and distinct periods of each, usually lasting for months at a time, with bouts of clean euthymia (wellness) in between.

I haven’t really experienced prolonged euthymia, instead merely catching glimpses of it over the course of my continuous ups and downs. My manias are “dirty” and dysphoric, tainted with depressive themes. My hypomanias are very productive; but if my mood spikes too high, my thoughts become dark and gruesome. If I were to jump off a building, it would be to kill myself, not because I believed I could fly.

And I’m also a researcher. Without a doubt, my research in the area of bipolar disorder draws upon my insights as a bipolar person. If I had “classic” bipolar disorder, the research I have done (some of it relying theoretically upon data collection of my own personal changes in mood) would not have been possible. Because I’m an ultra-rapid-cycler, I was able to capture long-term patterns that might take many years to become evident in “classic” bipolar disorder. I believe the same patterns exist in both, but when moods last for months at a time, it is harder to see those patterns.

My ability to detect patterns has served me well in life (including in my professional career) and to some extent, my bipolar disorder trained me to do it. Predicting my own mood was not only possible, thanks to the accelerated timeframe, but essential to my ability to cope with them. Part of the devastation of mixed episodes came with the loss of my ability to predict with reasonable accuracy when moods would peak or change and in what direction. Even so, I learned new patterns and slowly became able to tell what a “mixed episode” felt like, and whether I was experiencing one. This was not something I could do at first.

Insight into the emotions, cognitions, and memory issues that come along with my bipolar disorder developed over time, starting at an early age (as I first developed symptoms around the age of 10). In turn, this level of insight has allowed me to hypothesize connections no other researcher has yet seen. I understand firsthand how bipolar disorder intersects with changes in thinking and memory.

I have the opportunity to discern cause and effect in relation to changes in my mood much more easily than someone with “classic” bipolar disorder, thanks to the immediacy of any reactions. Upon hearing from my psychiatrist that nitrates in beef jerky were causally linked to mania, I took note of my own reactions. I had known for quite some time that beef jerky had a stimulant-like effect on me, but I was surprised to learn it did not have this effect on everyone. (Too bad!) I experience this stimulant-like effect almost instantly, while I’m still eating. The temporal proximity of the cause and the effect makes them easier to distinguish.

My bipolar disorder is a blessing and a curse. I have struggled immensely to control it, but I wouldn’t trade it for “classic” bipolar disorder or no bipolar disorder at all. The knowledge and abilities I have gained as a result of my battle with bipolar disorder — my bipolar disorder, not someone else’s — have actually, truly been indispensable to my life and my career. Plus, that excessively productive hypomania is pretty good too.
