What Bipolar Disorder Is and How It Differs From Other Conditions

Bipolar disorder is a mental health condition that affects how a person's mood, energy, and ability to function change over time. The word "bipolar" means "two poles," referring to the two main mood states people with this condition experience: episodes of very high mood (called manic or hypomanic episodes) and episodes of very low mood (called depressive episodes). These mood shifts are more extreme than the typical ups and downs everyone experiences.

During a manic episode, a person might feel unusually energetic, talkative, and confident. They may need very little sleep but still feel rested. Their thoughts might race, and they may take on many projects or spend money impulsively. Some people describe it as feeling "on top of the world." A hypomanic episode is similar but less severe and typically doesn't cause significant problems in daily life.

During a depressive episode, a person might feel deeply sad, hopeless, or empty. They may lose interest in activities they normally enjoy, sleep too much or too little, feel tired all the time, and have trouble concentrating. In severe cases, thoughts of suicide may occur. These episodes can last for weeks or months.

Bipolar disorder is different from regular depression or sadness. A person with depression experiences low mood persistently, while someone with bipolar disorder cycles between high and low moods. It's also different from other conditions like anxiety disorders or ADHD, though a person can have bipolar disorder alongside these other conditions. According to the National Institute of Mental Health, approximately 2.6 million adults in the United States have bipolar disorder in any given year.

Practical takeaway: Understanding the difference between bipolar episodes and everyday mood changes helps you recognize whether testing might be worth discussing with a healthcare provider. Manic, hypomanic, or depressive episodes that significantly interfere with work, school, relationships, or sleep patterns are different from temporary stress or sadness.

Why Testing for Bipolar Disorder Matters

Getting tested for bipolar disorder can be important because the condition often goes undiagnosed for years. Many people with bipolar disorder are initially diagnosed with depression alone, which can delay receiving the right treatment. Others may not realize their mood patterns are caused by a medical condition and instead think they simply have poor self-control or personal flaws.

Early identification matters because bipolar disorder typically begins in late adolescence or early adulthood, though it can start at any age. The longer someone goes without an accurate diagnosis, the more their relationships, education, career, and health can be affected. Untreated bipolar disorder increases the risk of substance misuse, as some people attempt to manage extreme moods on their own using alcohol or drugs. It also increases suicide risk—people with bipolar disorder have higher rates of suicide attempts than the general population.

When someone receives a proper diagnosis, they can start appropriate treatment. This might include medication, therapy, or both. Many people with bipolar disorder who receive correct treatment report significant improvements in their quality of life, stability, and ability to work and maintain relationships. Treatment can reduce the frequency and severity of episodes and help people recognize early warning signs.

Testing also rules out other conditions that might cause similar symptoms. Thyroid problems, neurological conditions, or medication side effects can sometimes create mood changes that look like bipolar episodes. A thorough evaluation helps ensure the real cause is identified. Additionally, understanding whether someone has bipolar disorder helps them make informed decisions about lifestyle factors like sleep, stress management, and substance use—all things that can trigger episodes or help maintain stability.

Practical takeaway: If you've experienced periods of significantly elevated mood alongside periods of depression, or if you have a family history of bipolar disorder, discussing testing with a healthcare provider can lead to an accurate diagnosis and appropriate support.

Signs and Symptoms That Might Lead Someone to Seek Testing

People often seek bipolar disorder testing after noticing patterns in their mood and behavior over time. Common signs during a manic or hypomanic episode include: racing thoughts that feel hard to slow down, significantly decreased need for sleep (feeling rested after only 2-3 hours), increased goal-directed activity (starting many projects), poor decision-making (large purchases, risky investments, reckless driving), increased talking or feeling pressured to speak, easily distractible attention, and increased confidence or self-esteem that feels different from normal.

During depressive episodes, signs might include persistent sad or empty mood lasting most of the day, loss of interest or pleasure in activities once enjoyed, significant changes in appetite or weight, sleep problems (sleeping too much or too little), fatigue or loss of energy, feelings of worthlessness or guilt, difficulty concentrating or making decisions, and recurrent thoughts of death or suicide.

Beyond mood and energy changes, some people notice patterns in their life. They might recognize that they have a family history—bipolar disorder runs in families, and having a parent or sibling with the condition increases risk. Others recall that major life events or stressful periods triggered mood episodes. Some notice their patterns correlate with seasons (more depressive episodes in winter, for example) or with changes in sleep schedule.

It's important to note that having occasional bad moods, stress-related sleep loss, or even temporary excitement about a project doesn't indicate bipolar disorder. For a diagnosis to be considered, episodes must be distinct from a person's normal baseline, last for a defined period of time, be noticeable to others, and interfere with functioning. A healthcare provider examines whether patterns suggest bipolar disorder or another condition entirely.

Practical takeaway: Keep track of your mood patterns, energy levels, sleep needs, and major life events for a few weeks or months. Note whether these patterns repeat or seem cyclical. This information can be valuable to share with a healthcare provider during an evaluation.

What to Expect During a Bipolar Disorder Evaluation

A bipolar disorder evaluation typically involves several components. First, you'll meet with a mental health professional or physician who will conduct an interview. They'll ask detailed questions about your mood history, including when mood changes started, how long episodes last, how severe they are, and what happens before, during, and after episodes. They'll ask about sleep patterns, energy levels, and periods of increased or decreased productivity.

The provider will ask about your personal history—major life events, relationships, work or school performance, and whether mood changes seem to follow any pattern. They'll want to know about your family history, since bipolar disorder has genetic components. They'll also ask about substance use, since drugs and alcohol can trigger or worsen mood episodes. Questions about suicidal or self-harm thoughts may be included; this is standard practice and helps the provider understand safety concerns.

You might complete written questionnaires or rating scales designed to measure mood symptoms and severity. Common tools include the Mood Disorder Questionnaire (MDQ), which screens for bipolar disorder, or the Patient Health Questionnaire (PHQ-9), which assesses depression. These aren't diagnostic by themselves but help organize information and ensure nothing is missed.

The provider may also conduct a physical examination and order blood tests. Thyroid function tests are common because thyroid problems can mimic bipolar symptoms. Depending on circumstances, other medical tests might be considered. A psychiatric evaluation may include questions about psychosis (hallucinations or delusions), since severe bipolar episodes can include these features.

The entire evaluation typically takes an hour or more. You might meet with one provider or see multiple specialists. If bipolar disorder is being considered, you may be referred to a psychiatrist (a medical doctor specializing in mental health) for further evaluation and potential medication management.

Practical takeaway: Before your evaluation appointment, write down when your mood episodes occur, how long they last, what you're doing when they start, and how they affect your daily life. Bring this information along with a list of any medications or supplements you take and your family mental health history. Being organized helps the provider gather the information they need efficiently.

Types of Bipolar Disorder and How Testing Distinguishes Them

Bipolar disorder isn't a single, uniform condition. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) recognizes different patterns. Bipolar I Disorder involves at least one manic episode (extreme high mood lasting at least one week) along with depressive episodes. A person with Bipolar I has experienced the most severe form of elevated mood.
