The FourTypes of Bipolar Disorder. What’s actually the difference?
Bipolar disorder isn’t one-size-fits-all.
When I say, “I’m bipolar,” I’m talking about Bipolar I Disorder, because that's my diagnosis. But Bipolar I is only one diagnosis under the bipolar umbrella, and understanding the differences matters.
One of the biggest misconceptions about bipolar disorder is that it always looks like the dramatic, extreme version we tend to see portrayed in movies and television. It doesn’t. There are four main diagnostic categories you may hear when talking about bipolar disorder, and even within those categories, no two people will experience it exactly the same way.
Before we break them down, let's answer a question I hear a lot.
ASK LOUISE: Can Bipolar II Turn Into Bipolar I?
This question came up in "I'm Bipolar. Now What?" LIVE, my weekly live coaching community, where we talk about the real-life work of building and protecting stability. We meet every week. Reply "LIVE" to learn about the next cohort.
My Answer:
Yes, but there's an important distinction.
If someone diagnosed with Bipolar II later experiences a full manic episode, they would then meet the diagnostic criteria for Bipolar I.
That doesn't necessarily mean their bipolar disorder suddenly “turned into” something else. Bipolar II is defined by a history of hypomania and major depression without a history of mania. Once a full manic episode occurs, that person's history now meets the criteria for Bipolar I.
And once someone has experienced a true manic episode, the diagnosis is Bipolar I, even if they never experience another one.
This is also why understanding the difference between hypomania and mania matters so much, which we'll get into below.
But first, let's look at the four types.
1. Bipolar I Disorder
This is my diagnosis.
Bipolar I is defined by experiencing at least one manic episode. Depression is extremely common in Bipolar I, but interestingly, a major depressive episode is not actually required for the diagnosis.
And mania is more than being really happy, energetic, productive, or impulsive. A manic episode involves a significant change in mood, energy, and functioning that lasts at least a week—or is severe enough to require hospitalization. It can include very little need for sleep, racing thoughts, rapid speech, inflated confidence or grandiosity, increased activity or agitation, impulsive or high-risk decisions, and significant impairment in everyday functioning. In severe cases, mania can also include psychosis.
For me, mania didn't necessarily feel like illness while I was inside of it. Sometimes it felt like confidence, creativity, energy, and possibility. That's part of what made it so difficult to recognize.
Until it wasn't.
And the higher I flew, the harder I eventually crashed.
2. Bipolar II Disorder
This is probably the one I see misunderstood most often: Bipolar II is not “mild bipolar.”
Instead of full mania, someone with Bipolar II experiences hypomania along with episodes of major depression. Hypomania shares many characteristics with mania, more energy, less sleep, increased confidence, faster thoughts, increased activity and impulsivity, but it does not reach the severity of a full manic episode.
Importantly, hypomania does not include psychosis.
The depressive episodes associated with Bipolar II can be severe, prolonged, and incredibly disruptive. The difference between Bipolar I and Bipolar II is about the type of mood episodes someone experiences, not how much they're suffering.
3. Cyclothymic Disorder
Cyclothymic disorder involves ongoing fluctuations between hypomanic symptoms and depressive symptoms that don't meet the full criteria for hypomanic episodes or major depressive episodes. In adults, these patterns persist for at least two years.
Think of it less as distinct, clearly defined episodes and more as chronic cycling between emotional highs and lows. And just because the symptoms don't cross certain diagnostic thresholds doesn't mean they aren't disruptive. Living with persistent mood instability can have a huge impact on relationships, work, identity, and everyday life.
4. Other Specified and Unspecified Bipolar and Related Disorders
And then there are people whose symptoms clearly fall somewhere within the bipolar spectrum but don't fit neatly into the diagnostic boxes above.
Other Specified Bipolar and Related Disorder is used when a clinician can identify why someone's symptoms don't meet the full criteria for another bipolar diagnosis. Unspecified Bipolar and Related Disorder may be used when there isn't enough information, or a clinician doesn't specify exactly why the full criteria aren't met.
I think this category is also an important reminder that human beings don't always fit perfectly into diagnostic boxes. A diagnosis gives clinicians a framework for understanding and treating what we're experiencing. It isn't the entirety of who we are.
Hypomania → Mania → Psychosis: What's the Difference?
These words get thrown around constantly, so let's actually talk about what they mean.
First, this is not a guaranteed progression. Someone can experience hypomania without it progressing to mania. Someone can experience mania without experiencing psychosis. And not everyone with bipolar disorder will ever experience psychosis. But for some people, an elevated mood episode can escalate, which is why understanding the differences and knowing your own warning signs can be so important.
Hypomania
Hypomania is a noticeable period of elevated, expansive, or irritable mood accompanied by increased energy or activity lasting at least four consecutive days.
You might sleep less, talk more, think faster, feel unusually confident, or become more social, creative, sexual, productive, ambitious, or impulsive. And here's what makes hypomania particularly tricky: it can feel fucking fantastic.
You may still be functioning. In fact, you may feel like you're functioning better than usual. People around you may even reinforce it: You're killing it. You're so productive. You seem amazing.
But something has changed. And recognizing that change matters.
Mania
Mania crosses a different threshold. The elevated or irritable mood and increased energy become severe enough to cause significant impairment, require hospitalization, or involve psychosis.
Judgment can become significantly impaired. Risk-taking can escalate. The need for sleep can dramatically decrease. Thoughts and speech may become increasingly difficult for other people to follow. Grandiosity can become extreme. And the person experiencing it may have very little insight into how unwell they've become.
This is one of the cruelest things about mania: You can become less capable of recognizing that you need help at exactly the moment you need it most.
Psychosis
Psychosis is different from mania. It's a loss of contact with reality.
It can include delusions, which are firmly held beliefs that aren't based in reality, and hallucinations, which involve perceiving something that isn't actually there, for example, hearing or seeing things other people don't.
Someone experiencing psychosis may genuinely be unable to distinguish between what is real and what isn't. Psychosis can occur during severe mania in Bipolar I, and it can also occur during severe depressive episodes.
And this distinction is important: Mania does not automatically equal psychosis. But if psychosis occurs during an elevated mood episode, you're no longer talking about hypomania. That episode meets the severity threshold for mania.
So… Which Type Is the “Worst”?
I don't think that's a particularly useful question.
Bipolar I isn't automatically “worse” because it includes full mania. Bipolar II isn't “easier” because it doesn't. Cyclothymia isn't something to dismiss because individual symptoms may not cross certain diagnostic thresholds.
Different doesn't mean more or less valid.
And even two people with the exact same diagnosis can experience bipolar disorder completely differently. That's one of the biggest things I've learned in the decade since receiving my Bipolar I diagnosis.
There are diagnostic criteria. There are common symptoms. There are patterns we can learn from. But then there is your bipolar disorder, your warning signs, your triggers, your patterns, your treatment, and your version of stability.
Learning those things has been one of the most important parts of learning how to live well with mine.
What If You Think You Might Be Bipolar?
First: trust your gut.
If something feels off, if your moods, energy, sleep, behavior, spending, relationships, confidence, productivity, or decision-making seem to move in patterns that feel bigger than ordinary ups and downs, pay attention to that.
You don't need to diagnose yourself. But you also don't need to ignore yourself.
Talk to someone you trust. A partner, friend, sibling, parent, someone who knows you well and may have noticed patterns you can't always see from the inside. Ask them what they've observed. Sometimes the people closest to us can see changes before we can.
Start tracking your moods and behavior. Pay attention to sleep, energy, irritability, impulsivity, spending, sex drive, productivity, social activity, substance use, and anything else that seems to shift with your mood. You're looking for patterns over time, not trying to analyze every individual good or bad day.
And most importantly, see a mental health specialist, ideally someone experienced in mood disorders and bipolar disorder specifically. When you do, bring the bigger picture. Bipolar disorder is often about patterns over time, not how you happen to feel during one appointment. Share your history, your highs, your lows, changes in sleep and behavior, and what other people have noticed, not just how you feel today.
And please, trust yourself enough to get another opinion.
If a diagnosis doesn't make sense to you, ask questions. If you don't feel heard, find someone else. Get a second opinion. Get a third opinion if you need one.
I spent years being treated for pieces of what I was experiencing before anyone finally zoomed out to see the whole picture.
Because bipolar disorder can look like depression. It can look like anxiety. It can look like addiction. It can look like incredible productivity. It can look like someone who has everything together.
Sometimes getting the right answer takes time.
Keep asking questions until you feel like someone is actually looking at the whole story.
A diagnosis can be scary. But for me, finally understanding what I was dealing with was also the beginning of learning how to manage it.
What If You Think Someone You Love Might Be Bipolar?
This one is complicated, because when you love someone, you want to help. You may be watching behaviors that concern you, recognizing some of the patterns I've described here, or reading this entire newsletter thinking, Holy shit. This sounds exactly like someone I love.
But here's something I can tell you from personal experience: being told you're bipolar by someone else doesn't always go particularly well. Trust me.
Long before I was diagnosed, an ex-boyfriend decided he had figured out what was “wrong” with me. His method of breaking the news? Handing me a printout about bipolar disorder with passages highlighted in yellow that he thought sounded like me.
Spoiler alert: I did not respond well.
You can read a whole lot more about that relationship, and what happened before, during, and after it, in my memoir, Tainted Love: A Bipolar Memoir
The irony, of course, is that months later I would be diagnosed with Bipolar I Disorder. But being right about someone's diagnosis and being the right person to diagnose them are two very different things.
So what should you do?
You know your relationship with your loved one better than I ever could. There isn't one perfect script or approach that works for every person or every relationship. But the best guidance I can give you is this: keep loving and keep learning.
Learn about bipolar disorder. Learn about mania and hypomania. Pay attention to patterns. Listen without immediately trying to fix. If it feels appropriate in your relationship, you can share what you're noticing and encourage them to talk with a mental health professional without declaring, “I think you're bipolar.”
And remember: it is not your job to diagnose them.
You can love someone. You can learn. You can observe. You can encourage them to seek professional help. And if they eventually receive a diagnosis, you can support their treatment plan.
But you don't need to become the treatment plan.
Sometimes the most powerful thing we can do for someone we love isn't figuring out what's “wrong” with them. It's continuing to be there while they figure out what they need. ❤️🩹
THIS WEEK'S JOURNAL PROMPT
What changes first for you? Your sleep? Energy? Speech? Spending? Sex drive? Irritability? Confidence? Social media use? Productivity? Thoughts?
You don't need to have all the answers. Start by paying attention.
Because the goal isn't to become terrified of every good mood or productive day. It's learning the difference between feeling good and becoming unwell.
And the better we know our own patterns, the earlier we can recognize when something is changing, and use the tools we've built before things escalate. ❤️🩹
xoxo,
Louise
