Recently, on Twitter, I confessed that I had not been able to complete reading NeuroTribes (a very interesting book, and also a lengthy one). The other person insisted that a PhD student should be able to read a book and accused me of lacking academic integrity — basically, that I am lazy and don’t deserve my PhD.
I’m here to say that attitude is inherently ableist. But to give the benefit of the doubt, perhaps most people don’t know that bipolar disorder actually can affect your ability to read. I learned to read early as a child — I was a prolific consumer of text, and I had a college reading level in elementary school (this is called hyperlexia). But after being medicated for bipolar disorder, my ability to sustain focus and momentum while reading a long document has been very limited.
Lithium is probably the biggest offender. It kind of affects how you see words on the page — like a pseudo-dyslexia, the words seem kind of blurry and distorted. It can be impossible to read full books. I can still read journal articles because they generally have a defined structure and an abstract. I can also read poetry, which I enjoy. I recommend seeking out these kinds of texts if reading is something you struggle with.
Most of all, I want you to know that this is common, you are not alone in having an acquired inability to read and you still deserve your career, whatever that may be. It’s not a matter of “intellectual thoroughness”; it’s part of a disability, and it’s more common than you think.
I also find it difficult to watch videos, TV, or movies. The information conveyed through video media covers many modalities — sound (music), speech, visuals, movement (spatial), and the overall plot you’re supposed to be following. Sitting for the length of a movie is hard, but it’s also just hard to follow so many things at once. My brain gets overwhelmed with too much information of different kinds to process (evidence of poor sensory integration, a symptom of autism). But it helps to reduce the overload by using captions (combining speech with visuals, thus reducing the number of information modalities) or watching something animated, which compresses the demands of visual and spatial information greatly.
There is much that could be written about the damage done by bad psychiatrists, but this post will specifically focus on non-psychiatric medical professionals: doctors, nurses, everyone involved with it.
Once I presented to the ER with a large abscess from a skin infection, and in great pain. I told the triage nurse that I had this abscess, and showed it to her (it was not subtle). She proceeded to look through my chart and started asking me about my bipolar disorder. I told her what she asked, and of course we got to “Are you planning to hurt yourself?” and I said no, because I wasn’t, I just really needed my abscess to be drained by a doctor.
Naturally, then, she put me in psychiatry and had a psychiatrist come speak to me. I told the psychiatrist what I told the nurse and showed him the abscess. He was horrified by it, and said he’d call my psychiatrist. After he spoke to her, he moved me to the medical area and gave his psychiatric stamp of approval. Finally, a medical doctor arrived and drained my abscess.
In retrospect, is it a big problem? I think it is. What if my condition were even more time-sensitive? They wasted significant time getting me a psych eval when I was not presenting with any major psychiatric symptoms, I just happen to have a chronic mental illness that I will have in my chart forever. What if I was having a heart attack? Would I have to get a psych eval because I’m bipolar?
If you have a label like “bipolar disorder type 1” they will always look for a psychiatric cause for your symptoms, even when the evidence doesn’t suggest it’s psychiatric (like, the huge abscess). They assume you are professionally crazy and anything you say is cause for suspicion, instead of an honest report of symptoms. Putting patients presenting with tangible physical illness in the psych area just because they have a diagnosis, but are not presenting with symptoms, is discrimination.
Recently, The Mighty published an article about the differences between anxiety and hypomania. However, I wanted to complicate the discussion by bringing up something that breaks the juxtaposition of anxiety and mania: primarily anxious mania, which is most likely a mixed episode associated with bipolar type 1.
The author describes how her anxiety leaves her “immobilized”. This can actually happen in mania, too — but usually not in hypomania. Hypomania is often very productive. Full mania is no longer productive — it’s frantic, potentially confused, and may be characterized by manic stupor. Emil Kraepelin used this term to describe a flight of ideas and elevated mood (not necessarily happy, but revved-up) combined with psychomotor slowness or immobility. I’ve been in this state, and I experienced it subjectively as intense feelings of anxiety paralyzing my every move. This might also be referred to nowadays as catatonia, and something similar can occur in severe depressive states; however, the catatonia that coincides with mania is likely excited catatonia (characterized by purposeless movements rather than being completely still).
Hypomania isn’t rare, exotic, or exciting to me. It’s just part of my life, and I take advantage of it when it comes around — which it will, no matter what. But, to me, full mania is to be avoided. Anxiety is also a daily part of my life, but the anxiety and paranoia I experience during a manic episode is even more excruciating than it usually is. Juxtaposing them as discrete, separate states can only take you so far in understanding what mania is and how it affects people.
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):
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.
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.
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).
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.
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.
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.
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)…
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.
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.
The goal of medication isn’t to make everyone neurotypical. That would be boring as fuck. — Dr. Coats (my psychiatrist)
Different psychiatrists no doubt have different philosophies about the point of psychiatric medication, and different patients have their own goals for treatment which naturally vary. To some people, bipolar disorder is a gift to be tamed; to others, it’s a curse to be extinguished. Regardless of whether you choose to take medication for bipolar disorder or not, you surely have your reasons for doing so. Many of these reasons seem to hinge on what the perceived goal of treatment is.
Some goals are specific: for example, “I’d like to be able to go back to school and get my degree”. Some goals, on the other hand, are more vague: “I’d like to be well again”. What does it mean to be well? Certainly, it means different things to different people.
As my psychiatrist, Dr. Coats, has said, the goal of psychiatric medication isn’t to make everyone neurotypical. There are some psychiatrists who may believe that the optimal outcome for everyone looks like neurotypicality (the complete suppression of bipolar symptoms to look like a “normal” person), but for many people with bipolar disorder this isn’t one of their goals. Furthermore, for many people with bipolar disorder it simply won’t happen.
One study that followed 258 outpatients, all of whom were taking medication, for one year found that 63% had four or more mood episodes within the year.1 26% were ill for more than 3/4 of the year. It seemed that medication was more effective at controlling mania than depression, as participants spent 3 times more time in depressive states than in manic states. A wide variety of drugs were prescribed to participants in this study, including mood stabilizers, anticonvulsants, antidepressants, benzodiazepines, and thyroid medications. The average participant took 4 different medications. Despite this, only 11% of participants were virtually free of mood symptoms. 89% experienced symptoms to some degree.
The study identified many subgroups of bipolar participants, each with a distinct pattern of recurrence (or non-recurrence) of mood symptoms. For example, of the 26% who were ill for 3/4 of the year or more, there were several subgroups: A) ultra-rapid cyclers who were essentially ill for the entire year, B) those with predominant depressive episodes (but experienced mood cycling), C) those with predominant manic episodes, and D) those who had chronic persistent depression with very little cycling.
Based on which pattern is most accurate to describe a given individual, it would be appropriate to adjust one’s goals and expectations for treatment with medication. When I’m ill, I’m closest to pattern A. My goals include slowing down my cycling, reducing the severity of mood symptoms and suicidal thoughts, suppressing my impulsivity and anger, and sleeping regularly each night. For someone with pattern D, goals might look a bit different.
I think it’s helpful to identify specific goals. This helps you determine if you’ve made any progress towards what you want to achieve, even if you still experience symptoms. For many people, resuming a completely normal life with no symptoms of bipolar disorder may be a futile effort — or an unwanted outcome. Even in my most well periods I experience cyclothymic changes in mood and energy levels. My work style is somewhat erratic, and I might stay up for 2 or 3 days working on a paper until it’s finished, then be unproductive for a month or two. My goals aren’t to extinguish these features. I’m not trying to be neurotypical. I’m trying to protect my life and reduce suffering.
Because while bipolar disorder can come with tremendous gifts, it can also be the source of unbelievable pain and suffering. Only you can decide how to reconcile that in your own life. And if stifling mood episodes completely isn’t your goal, that’s okay. It’s possible that you can still harness the benefits of medication to reduce suffering. I recommend being honest about your goals to your treatment team. A good psychiatrist shouldn’t be forcing neurotypicality onto you. Being bipolar in itself isn’t a bad thing.

There’s no doubt in my mind that Van Gogh had bipolar disorder. He had many symptoms related to bipolar disorder: manic episodes, depressive episodes, hallucinations, sleep disturbance, substance abuse, memory problems, nightmares, and anxiety, to name a few from his asylum files.
Yet, additional diagnostic labels could help to clarify his overall presentation. One diagnosis that has been put forward is BPD. It does seem to explain some of the events of his life, for example, his heated interpersonal conflicts and fears of abandonment related to Paul Gauguin. However, a diagnosis of autism has not been seriously considered. This is interesting in light of the heightened prevalence of bipolar disorder in autism — an autistic person is as much as 8.5 times more likely to have bipolar disorder than a non-autistic person (this number assumes no intellectual disability and a diagnosis before age 28).1 Another study found that 7% of autistic people also had bipolar disorder.2
As a child Van Gogh was described by his younger sister as “intensely serious and uncommunicative, and walked around clumsily as if in a daze, with his head hung low”, and went on to say that he was like a stranger both to his siblings and to himself. A servant said he was “an odd, aloof child who had queer manners and seemed more like an old man” than a child.3 These are characteristics often ascribed to some autistic children, even poor motor coordination (dyspraxia).
Vincent was deeply intelligent, thoughtful, and demonstrated what seemed like the capacity to be successful, but as a young man he struggled to find a vocation that could accommodate him. He drifted from an art dealership (where he was fired for arguing with buyers), to a teaching job, to a minister’s assistant for a Methodist church, to a bookshop where he reportedly doodled and translated parts of the Bible into English, French, and German, to religious studies. He failed his entrance exam in theology and his missionary course. Religion was a special interest for Van Gogh. He was endlessly devoted and passionate about the subject, but his odd behavior made him an ineffective preacher, and he was not a good student.
Van Gogh had severe social problems which seem to have started early in his life. People repeatedly thought that he was odd, and they didn’t want to be around him. His peculiarities were off-putting. Children were scared of him. Scholars suggest that he did not understand the concepts of diplomacy or salesmanship, that he lacked insight into the thought processes of others, and lacked the ability to cognitively understand their emotions and motivations.3 He was emotionally dysregulated and prone to agitated or impulsive meltdown behaviors. As his interest in painting became more intense and all-consuming, he neglected maintenance of his body or appearance, appearing even more eccentric.
One of the highlights of Van Gogh’s medical files that has yet to be parsimoniously explained is his chronic stomach issues. In particular, gastrointestinal problems seem to be an important feature of autism4 although bipolar disorder may also be related to stomach problems.
Finally, there’s the most obvious trait of Van Gogh’s: his artistic ability. Many people have suggested that Vincent might have had some form of synesthesia. Further, I hypothesize that hue discrimination may, like pitch discrimination, be enhanced in some autistic people.5
A diagnosis of autism didn’t exist in Van Gogh’s time — in fact, wouldn’t exist for over 50 years after his death. Perhaps it’s not so surprising that the autism connection has been overlooked. Vincent van Gogh’s wild, reckless nature combined with intellectual and artistic sensibilities (and lack of mathematical talent) defies narrow stereotypes of autism, yet embodies a certain reality of it: he was thoughtful yet lacked insight, seen as a stranger by the world around him while experiencing the world as fundamentally strange, and possessed incredible gifts yet was understood as deficient. Maybe it’s time to look beyond famous scientists and mathematicians for autistic historical figures.

For me, mixed episodes are the worst part of my bipolar disorder. It’s hard for people without bipolar disorder to comprehend how it could be that you feel mania and depression at the same time. It doesn’t have to be simultaneous, per se — it could just be very quickly alternating — but for me it is, at times, simultaneous.
In actuality, mixed episodes aren’t rare. The most common presentation of bipolar 1 disorder is a combination of depression and mixed episodes (32%), followed by the combination of depression and manic episodes (30%; Grant et al., 2005). Mixed episodes are also common in bipolar 2 disorder (Benazzi et al., 2004) although, understandably, these tend more towards the depression side.
To understand my own mixed episodes, I draw a distinction between physical and mental energy. Mania typically involves high levels of both physical and mental energy: you feel physically great, you never seem to get tired, and your thoughts and ideas might be racing around in your head. In contrast, depression involves low physical and mental energy: you’re tired and sluggish, you might be in pain, and your thoughts feel jammed like a printer that just won’t print.
My own mixed episodes tend to feature low physical energy and high mental energy. I can’t sleep at night because my thoughts keep me awake, but instead of feeling ready to go in the morning, I feel tired and miserable. I may pace around because of all the energy inside my head, but my body aches constantly. I tend to become very preoccupied with suicide. Mixed episodes are the most dangerous time for me.
I also might have hallucinations during mixed episodes, and they’re distinctly unpleasant. One that recurs for me is the bugs. I start out by feeling them crawling on my skin, particularly when I lie down in bed to try and sleep at night. No matter how many times I meticulously check my pillow, I can’t find any bugs, but I know they’re there (and know they’re not there — simultaneously). At times, though, this has progressed further to actually seeing bugs everywhere around my apartment, and not being able to tell which are real and which are imagined (because there probably were some real bugs). I once came to the conclusion that not all of the bugs could be real because there were simply too many different species living in my studio apartment. On another occasion, I heard voices mocking me from inside my dishwasher.
Other times, I acquire some delusional or near-delusional beliefs. I have been absolutely convicted that I had AIDS in one instance, Parkinson’s disease in another. I don’t have either of these diseases, but I couldn’t be dissuaded from my belief, at least in the moment. When I believed I had AIDS, I even started writing goodbye letters.
Though I’ve never departed too far from reality, personally — just wandered a little bit astray. I’ve been underwater, but always close enough to see the light on the surface. Some people experience psychosis in a much more encompassing way. Hallucinations and delusions can be truly terrifying, even life-changing experiences. Mine seem a bit mundane in comparison. No angels, no demons… just bugs.
One could also envision a mixed episode with high physical energy and low mental energy. This might result in a kind of catatonic state, probably an agitated catatonia. This is considered a very dangerous state in its own right because catatonic patients are less than fully conscious of their actions, and if they are very agitated, they could pose a risk to themselves and others around them.

People with bipolar disorder commonly have memory problems. This is actually something I’ve been doing research about as a PhD student at UCLA. Not only that, it’s something I struggle with myself.
There are two main categories of memory problems in bipolar disorder: problems that are associated with a mood episode, and problems that exist outside of mood episodes (during euthymia, or well periods).
During episodes of depression, problems with explicit memory are common. That’s the kind of memory you’re using when you try to recall facts or events — in contrast to implicit memory, which includes emotional learning (conditioning) and procedural learning (like learning how to ride a bicycle). Implicit memory tends to be preserved, but depressed people struggle to explicitly remember things. For example, trying to remember the names of past presidents might become extremely effortful. This is actually the same for unipolar depressives. Controlling for the severity of depression symptoms, bipolar and unipolar depressives are very similar in the area of memory performance (Bearden et al., 2006).
Memory impairments are more pervasive in manic episodes. Research has found that during a manic episode, people perform more poorly at tasks requiring episodic memory (the kind of memory you use when you remember a scene you’ve lived through, typically from a first-person perspective), working memory, spatial attention, and problem solving (Sweeney et al., 2000). Many people who have experienced manic episodes have a great deal of difficulty remembering what happened during the episode. It’s possible that mania disrupts the encoding of new memories (King et al., 2013). For some of us, this is a double-edged sword: it’s painful to remember, and yet it’s painful not to remember. Sometimes we’re left trying to piece together what actually happened while simultaneously part of us is trying to move on from it. Even worse, sometimes other people remember better than you do.
Problems with episodic memory aren’t limited to mania, though.
Various studies have shown bipolar people who are euthymic (not currently having a mood episode) to perform poorly at memory-related tasks. Problems with executive functioning frequently come up — these problems can be similar to people with ADHD. But one of the most noteworthy findings is impairment in episodic memory about one’s own life. In particular, it seems like memory for specific events is impaired, but memory for personal facts (like one’s name or birthday) are not affected (Shimizu et al., 2009).
It’s hard for me to remember a lot of things I’ve lived through. Not infrequently I meet people who tell me we’ve met before, but I have no idea who they are. I have friends that I don’t remember how or where we met. Even memories I’d like to keep seem not to stick very well, which is saddening. I forget most of what happens after a year or two. Sometimes the things I do remember are a little strange. According to my psychiatrist, I have an incredible ability to know exactly how many times she’s told me the same story in the past, but I don’t remember the contexts I heard it in.
One study (King et al., 2013) found that when they asked bipolar disorder patients to recall memories from their life, they were more likely to recall those memories from a third-person or observer perspective. It makes me wonder why that is. It’s like the people with bipolar disorder can’t remember being in their own head, even if they can “see” what happened in their memory. Something is disconnected between their past and present minds. They specifically can’t remember being themselves.
Bipolar disorder can be so much more than having emotional “ups” and “downs”. For some people bipolar disorder affects us every day and changes how we live life. Many people don’t realize how memory problems can affect us. When I write, I write about the present at least as much as I write about the past, because I know how transient the present really is.
Have you ever experienced something like this?
