Why Bipolar II Disorder Often Goes Misdiagnosed
Introduction: A Story We Hear Too Often
At Transcending Psychiatry, we hear this story all the time:
"For years, I thought I just had depression. The medications didn’t help. Some even made me feel worse. Then one day, a provider finally told me it might be Bipolar II. Suddenly, my whole life made sense.”
We’ve sat with people who carried this confusion for years. They worked hard in therapy, tried medication after medication, and still wondered, “Why don’t I feel better?” Families tell us they’ve blamed themselves, wondering if they missed something. And almost always, the answer lies in misdiagnosis.
So, how often is bipolar disorder misdiagnosed? Far more often than it should be. And Bipolar II, in particular, is one of the most commonly missed conditions we see.
How Often Is Bipolar Disorder Misdiagnosed?
You might be surprised, or maybe not if you’ve lived it, but studies suggest bipolar disorder is misdiagnosed in up to 60% of people. And when we look closely at bipolar II disorder diagnosis, the rate is even higher.
Why? Because hypomania (the elevated mood in Bipolar II) doesn’t look dramatic. It isn’t the dangerous, obvious mania that lands people in the hospital. Instead, it might look like a stretch of being extra social, productive, or confident. Parents sometimes say, “I thought she was just having a good week.” Teens may even be praised for being focused or creative during hypomanic phases.
But when the depressive episodes hit, they hit hard. And because those episodes dominate, many people end up with only a depression label. That’s how the misdiagnosis of bipolar disorder happens again and again.
When Did Bipolar Become a Diagnosis?
People often ask us, “When did bipolar become a diagnosis?” The answer is that bipolar disorder has been recognized for centuries, but it was called manic-depressive illness. In 1980, the DSM-III officially introduced the term bipolar disorder. Later editions, including the DSM-5 bipolar diagnostic criteria, added clarity about the difference between Bipolar I and Bipolar II.
Even with clearer standards, misdiagnosis persists because applying the bipolar diagnosis criteria of DSM-5 takes time, listening, and looking at a person’s life as a whole, something that doesn’t always happen in rushed healthcare settings.
Understanding Bipolar 2 Diagnostic Criteria
Let’s make this simple. According to the bipolar 2 diagnostic criteria:
You must have had at least one major depressive episode
You must have had at least one hypomanic episode lasting at least 4 days
You cannot have had a full manic episode (that would be Bipolar I)
The symptoms cause distress or impair daily life
This is what the bipolar II diagnostic criteria spell out. Yet many people tell us they never recognized hypomania in themselves. They just thought it was “being in a good mood.” One client told us, “I didn’t realize that my bursts of energy and racing ideas were part of the illness. I thought that was the only time I felt normal.”
This is exactly why bipolar disorder type 2 diagnostic criteria are often overlooked and why so many end up with the wrong diagnosis.
Differential Diagnosis for Bipolar II
Another reason Bipolar II gets misdiagnosed is that it looks like other conditions. That’s where the differential diagnosis for bipolar disorder is essential.
We often see people who were told they had depression, ADHD, anxiety, or even borderline personality disorder. Sometimes the overlap is so close that it takes time and careful listening to untangle.
Depression vs. Bipolar II: The depressive episodes are similar, but without recognizing hypomania, people are stuck with incomplete treatment.
Misdiagnosed bipolar or ADHD: Racing thoughts, restlessness, and impulsive behavior can look like ADHD, but the patterns are different.
Anxiety or personality disorders: Mood swings linked to trauma or stress can be confused with bipolar disorder, leading to overdiagnosis of bipolar disorder in some cases.
At Transcending Psychiatry, we spend time on the differential diagnosis of bipolar disorder, making sure we see the whole story, not just a single snapshot.
What Does Undiagnosed Bipolar Look Like?
So, what does undiagnosed bipolar look like? We see it in people who:
Struggling for years with depression that never seems to improve
Experience periods of high energy, creativity, or irritability that others dismiss as “just personality”
Make impulsive decisions during those phases, then feel crushed by regret later
Carry a quiet sense that something about their diagnosis never fully fit
One young man told us, “I always knew there was more to it. My depression didn’t act like everyone else’s. Finally getting the right bipolar type 2 diagnosis gave me answers I had been searching for my whole life.”
Can Bipolar Disorder Be Misdiagnosed?
Yes, every single day. Families ask us, “Can bipolar disorder be misdiagnosed? Can bipolar disorder be misdiagnosed as something else?” The answer is.
We’ve seen misdiagnosed bipolar or ADHD countless times. We’ve also seen people told for years that they had only depression, or trauma, or anxiety. And yes, we’ve seen the opposite too, overdiagnosing bipolar disorder when symptoms were actually due to other causes.
That’s why we believe diagnosis is not about checking boxes. It’s about knowing a person’s full story, applying the bipolar II disorder diagnosis criteria carefully, and walking alongside families as we sort out the truth together.
The Human Cost of Misdiagnosed Bipolar Disorder
The cost of getting it wrong is high. People spend years trying treatment after treatment. Families grow frustrated. Teens grow up into adults thinking they are “difficult” or “broken.”
One woman told us, “For over a decade, I was misdiagnosed with bipolar disorder when it was trauma. I lost years of my life to the wrong treatment plan.” Another said, “I was told it was depression. Nothing ever worked. When I finally received a true bipolar II disorder diagnosis, I felt relief for the first time.”
This is why accuracy matters so much to us. It’s not just clinical. It’s about restoring hope.
