The Hidden Signs of Bipolar Disorder Even Doctors Can Miss

Is it mood swings or bipolar disorder? Learn subtle symptoms and hidden signs most people—and even doctors—often miss.

When most people think of bipolar disorder, they picture intense mood swings—manic highs and depressive lows. But bipolar disorder is far more complex than that. Many individuals live with this condition for years without knowing it because their symptoms don’t match the classic extremes. Instead, they experience lesser-known signs of bipolar disorder that are easy to overlook or misinterpret.

According to the National Institute of Mental Health, about 4.4% of US adults will experience bipolar disorder at some point in their lives. Yet research shows that nearly 70% are misdiagnosed early on, and over one-third remain misdiagnosed for more than a decade. Why? Because the hidden signs of bipolar disorder often mimic other mental health conditions—or are dismissed entirely.

These subtle symptoms can leave people wondering: Is it mood swings or bipolar disorder? If you or someone you love struggles with emotional ups and downs, irritability, impulsivity, or periods of high energy that don’t quite seem “normal,” it’s worth a closer look.

In this article, we’ll explore the unrecognized symptoms of bipolar disorder, how they may show up in daily life, and what steps to take if you think bipolar disorder could be the cause.

Research shows that nearly 70% are misdiagnosed early on, and over one-third remain misdiagnosed for more than a decade.

WHY BIPOLAR DISORDER IS OFTEN MISSED OR MISDIAGNOSED

Many people assume bipolar disorder always involves extreme manic episodes, but that’s not the case. There are several types of bipolar disorder, including bipolar 1, bipolar 2, and cyclothymia. When it comes to bipolar 1 vs bipolar 2 and cyclothymia, the latter two involve milder forms of mania (hypomania), making them harder to recognize.

These episodes may not disrupt daily life in obvious ways, which is why people often don’t realize they have a mood disorder. The early signs of bipolar disorder in adults can include subtle mood shifts, impulsive behaviors, chronic irritability, and periods of extreme productivity.

Often, these symptoms can be spotted by those around you or if you’re aware and tracking your own behaviors. Unfortunately, there are often missed symptoms or confusing bipolar disorder signs most people miss that aren’t always discussed in mental health circles.

Common Misdiagnoses of Early Signs of Bipolar Disorder in Adults

Bipolar disorder is frequently mistaken for other mental health conditions, leading to delayed or incorrect treatment. This can be devastating if you’re unsure of how to talk about your symptoms with your doctors.

Other mental health conditions can “mask” early symptoms of bipolar disorder in adults, so it’s just as important to know the most common misdiagnoses to talk about it early.

  • Depression – Many people with bipolar disorder experience more depressive episodes than manic ones, also known as “rapid cycling”, leading doctors to diagnose unipolar depression instead.
  • ADHD – Impulsivity, restlessness, and difficulty concentrating are hallmark symptoms of both conditions.
  • Anxiety disorders – Periods of excessive worry and racing thoughts in bipolar disorder can be confused with generalized anxiety disorder (GAD).
  • Borderline Personality Disorder (BPD) – The emotional instability in BPD can resemble the mood swings seen in bipolar disorder. Though some may mistakenly interchange these mental disorders, their symptoms are distinct.

In this video, Dr. Steven Storage, a psychiatrist at Amen Clinics, discusses three key dissimilarities in these two mental health conditions.

Why Standard Mental Health Screenings May Fail

Traditional mental health assessments often focus on depressive symptoms rather than mood fluctuations, which means bipolar disorder can go unnoticed. A 2020 study found the average delay in diagnosing bipolar disorder can be 10 to 15 years from the onset of symptoms. This delay can prevent people from getting the right treatment early on.

SUBTLE SIGNS OF BIPOLAR DISORDER

Bipolar disorder doesn’t always involve extreme mood swings or obviously dramatic behavioral changes. Here are some lesser-known symptoms or often unrecognized symptoms of bipolar disorder:

  • Chronic irritability & angry outbursts – Unexplained frustration or sudden aggression without an apparent cause.
  • Unpredictable sleep patterns – Staying up late with high energy for days, followed by prolonged exhaustion for days.
  • Impulsive decision-making – Engaging in reckless spending, quitting jobs impulsively, or taking on unrealistic projects.
  • Periods of intense productivity (“hypomania”) – Feeling unstoppable, highly creative, or hyper-focused, but eventually burning out.
  • Feeling “high” on life without a reason – Experiencing sudden surges of confidence, optimism, or grandiosity. This can often lead to making impulsive choices with what should be clearly dangerous potential outcomes.
  • Depressive episodes that feel different from typical depression – A mix of deep sadness, agitation, and restlessness.
  • Unstable self-image – Fluctuating between feeling highly capable and worthless with other issues like body dysmorphia, imposter syndrome, or identity crisis.

THE EMOTIONAL ROLLERCOASTER: MORE THAN JUST MOOD SWINGS

Bipolar disorder isn’t just about mood swings—it affects your relationships, work, and daily routines in profound ways.

Bipolar Disorder and Relationships

Research shows that having bipolar disorder has a negative impact on relationships. In part, this is can be due to intense emotional reactions, impulsive behaviors, and periods of withdrawal.

Loved ones may feel confused by sudden shifts in mood and energy levels. Communicating your concerns and being transparent about what you’re each going through can help you find solutions to common problems when dealing with bipolar disorder.

The “Bipolar Hangover”

After a hypomanic episode, many people with bipolar disorder can experience what’s known as a “bipolar hangover”—a period of exhaustion, regret, and emotional depletion.

These post-hypomania hangovers can lead to feelings of guilt or embarrassment over actions taken during a hypomanic phase. It can also make it harder to recognize the pattern of mood swings because the emotional crash can be mistaken for ordinary stress or fatigue rather than a sign of the underlying condition.

The Risk of Self-Medication

Some people turn to alcohol, caffeine, or drugs to manage their fluctuating moods. Research reveals up to 60% of people with bipolar disorder struggle with substance abuse at some point in their lives.

However, self-medicating only worsens symptoms and increases the risk of long-term consequences. It is critical to your mental and physical health and safety to speak openly and honestly with your mental health professional and physician about using alcohol, marijuana, or other substances to self-medicate.

HOW TO TELL IF YOU HAVE SIGNS OF BIPOLAR DISORDER

If you suspect that you or someone you love may have bipolar disorder, here are some questions to start:

  • Do I experience periods of extreme energy or restlessness, followed by deep exhaustion?
  • Have I made impulsive decisions that I later regretted?
  • Do my moods shift dramatically without an obvious cause?
  • Have I ever felt “on top of the world” for no reason, only to crash into depression later?
  • Have mental health professionals diagnosed me with depression, ADHD, or anxiety, but treatments haven’t fully worked?

Keep a Mood Journal

Tracking your mood patterns over time can help identify hidden signs of those high and low emotions. To help identify the bipolar disorder signs most people miss, or if you just don’t know where to start, here’s a breakdown of what a mood journal should include:

  • Night/morning routine and sleep patterns
  • Energy levels throughout the day
  • Emotional state at the start and end of the day
  • Major life events and stressors

WHAT TO DO IF YOU RECOGNIZE THESE SIGNS

If you or a loved one exhibit these symptoms, early intervention for bipolar disorder is key, according to a review in the American Journal of Psychiatry. Tracking symptoms as soon as they appear can simplify the diagnosis process and development of an effective treatment plan.

Brain-Healthy Treatments for Bipolar Disorder

Some bipolar disorder interventions include:

  • Nutrition – A consistent diet rich in omega-3 fatty acids, lean proteins, complex carbohydrates, and micronutrient supplements supports mood stability.
  • Therapy – Cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) can help with emotional regulation.
  • Lifestyle – Regular exercise, stress management, and proper sleep hygiene play a crucial role in mood stability.
  • Medication – Mood stabilizers and other bipolar disorder medications may be necessary for some people after speaking with their doctor.

How To Talk to Your Doctor

  • Be honest about your mood fluctuations and impulsive behaviors.
  • Keep a detailed symptom tracking journal to share with your physician.
  • Ask about objective diagnostic tools like brain SPECT imaging for a more comprehensive evaluation.

Bipolar disorder isn’t always obvious, but recognizing the hidden signs can be life changing. If you or someone you love struggles with mood swings, impulsivity, or unexplained emotional shifts, seeking a comprehensive mental health evaluation is the next step.

To help rule out other mental health conditions, such as ADHD, clinical depression, and schizophrenia, consider seeking an evaluation that includes brain SPECT imaging. This functional brain imaging technology helps detect underlying brain activity patterns associated with a variety of mental health problems.

This leads to a more accurate diagnosis and more effective treatment. With the right treatment plan for bipolar disorder, stability, balance, and a fulfilling life are possible.
