Bipolar disorder is a mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). Proper diagnosis is crucial because the symptoms can sometimes overlap with other conditions like depression or anxiety. In this article, we’ll explore how bipolar disorder is diagnosed, the types of bipolar disorder, and the steps that mental health professionals take to ensure an accurate diagnosis.
Understanding Bipolar Disorder
What Is Bipolar Disorder?
Bipolar disorder is a lifelong condition that affects mood, energy, activity levels, and the ability to carry out day-to-day tasks. It’s often misunderstood as simple moodiness, but the intensity and impact of the highs and lows in bipolar disorder are far more severe.
Types of Bipolar Disorder
There are several types of bipolar disorder, each with unique patterns of mood swings:
Bipolar I Disorder: Characterized by at least one episode of mania that lasts for at least a week, often severe enough to require hospitalization. Depressive episodes typically follow but are not required for diagnosis.
Bipolar II Disorder: Involves at least one episode of hypomania (a milder form of mania) and one major depressive episode. Hypomania doesn’t cause the same severe problems as full mania, but it can still affect daily life.
Cyclothymic Disorder: Defined by periods of hypomanic and depressive symptoms lasting for at least two years (one year in children and adolescents). However, the symptoms are less severe than in Bipolar I or II.
Signs and Symptoms of Bipolar Disorder
Mania and Hypomania
Mania is more severe than hypomania and can lead to risky behaviors and extreme changes in mood and activity. Common symptoms of mania include:
Feeling overly energetic or “high”
Decreased need for sleep
Rapid speech or racing thoughts
Irritability or aggressive behavior
Engaging in risky activities, such as spending sprees or reckless driving
Hypomania includes similar symptoms but in a less extreme form. People experiencing hypomania may still function in their daily lives, but those close to them notice a change in mood and behavior.
Depressive Episodes
Depressive episodes in bipolar disorder are marked by:
Prolonged sadness or emptiness
Fatigue or lack of energy
Loss of interest in activities once enjoyed
Difficulty concentrating or making decisions
Thoughts of death or suicide
The Diagnostic Process for Bipolar Disorder
Diagnosing bipolar disorder requires a thorough evaluation by a mental health professional. The diagnostic process usually involves several steps to ensure the diagnosis is accurate and to rule out other conditions.
Step 1: Clinical Interview
The first step in diagnosing bipolar disorder is a detailed clinical interview. The mental health professional will ask about your mood, behavior, energy levels, and sleep patterns. They will also inquire about your family history since bipolar disorder can have a genetic component.
During this interview, it’s essential to be honest and provide as much information as possible. Some people with bipolar disorder may not recognize their hypomanic or manic episodes as problematic, so input from family members or close friends can also be helpful.
Step 2: Medical History and Physical Exam
Before diagnosing bipolar disorder, the healthcare provider may perform a physical exam or ask for a complete medical history. This step helps rule out physical health conditions, such as thyroid problems or neurological disorders, that can mimic symptoms of bipolar disorder.
Lab tests may also be ordered to ensure that there are no underlying medical conditions contributing to the symptoms.
Step 3: Mood Charting
Many clinicians ask patients to keep a mood diary or chart their emotions over several weeks. This method helps track patterns of mood changes and any triggers, such as stress or life events, that could influence mood swings.
Mood charting is especially useful in distinguishing between bipolar disorder and other conditions, such as major depressive disorder or anxiety, which may have overlapping symptoms.
Step 4: Diagnostic Criteria
Mental health professionals use specific criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose bipolar disorder. According to the DSM-5, a person must experience at least one manic or hypomanic episode to be diagnosed with bipolar disorder.
Manic Episode: A period of at least one week of elevated, expansive, or irritable mood, along with increased energy or activity.
Hypomanic Episode: A period of at least four days of similar symptoms to mania but less severe and not requiring hospitalization.
For Bipolar II disorder, at least one hypomanic episode and one major depressive episode are necessary for diagnosis.
Step 5: Differential Diagnosis
Bipolar disorder can be challenging to diagnose because its symptoms overlap with other mental health conditions. A key part of the diagnostic process is ruling out other disorders, such as:
Major Depressive Disorder: While people with bipolar disorder experience depressive episodes, they also have periods of mania or hypomania, which are absent in major depressive disorder.
Borderline Personality Disorder (BPD): Both bipolar disorder and BPD involve mood instability, but BPD mood changes are often triggered by interpersonal issues, whereas bipolar mood swings are more cyclic.
Schizophrenia: In rare cases, severe mania can be mistaken for psychosis, which is a hallmark of schizophrenia. However, the two conditions are distinct and require different treatments.

Tools Used in Diagnosis
Mood Questionnaires
Mental health professionals may use mood questionnaires or screening tools like the Mood Disorder Questionnaire (MDQ) or Bipolar Spectrum Diagnostic Scale (BSDS) to gather more information about mood patterns and the severity of symptoms. These tools help guide the clinician toward an accurate diagnosis but are not standalone diagnostic tools.
Neuropsychological Testing
In some cases, neuropsychological testing may be used to assess cognitive functions like memory, attention, and problem-solving. Cognitive difficulties are common in people with bipolar disorder, particularly during depressive episodes.
Why Accurate Diagnosis Matters
Getting the Right Treatment
An accurate diagnosis of bipolar disorder is critical for receiving the right treatment. Bipolar disorder is typically treated with a combination of medication and therapy. Mood stabilizers, antipsychotics, or antidepressants may be prescribed depending on the individual’s needs.
Avoiding Misdiagnosis
Misdiagnosis of bipolar disorder can lead to inappropriate treatments. For instance, if bipolar disorder is misdiagnosed as depression, a patient might receive antidepressants, which can trigger manic episodes in some people. Therefore, a correct diagnosis is essential for managing the condition effectively.
Final Thoughts
Bipolar disorder is a complex condition that requires a comprehensive diagnostic process. If you or someone you know is experiencing mood swings, it’s important to seek help from a mental health professional. Through careful evaluation, including interviews, medical history, and mood tracking, bipolar disorder can be accurately diagnosed, and the proper treatment plan can be developed.
Managing bipolar disorder is possible with the right diagnosis and support. Early diagnosis can help individuals lead fulfilling lives by managing their symptoms and maintaining a stable mood.
