Bipolar Disorder Symptoms: More Than Just Mood Swings

Bipolar disorder symptoms go far beyond ordinary mood swings. The condition involves distinct episodes of mania or hypomania and depression that change energy, sleep, thinking and behavior for days or weeks at a time, not just hours. Between episodes, many people feel steady. Recognizing the full range of symptoms is the first step toward an accurate diagnosis and effective treatment.

This guide is for adults and teens who wonder whether their highs and lows are more than moodiness, and for family members who have noticed patterns in someone they love. It explains the types of bipolar disorder, how episodes can look, why it is often missed, a step-by-step path to evaluation and when to get help right away.

This article is general information, not a medical recommendation. Do not start, stop or change any medication without talking to your prescriber.

Is bipolar disorder just mood swings?

No. Everyday mood swings are brief reactions to events, while bipolar episodes are sustained changes in mood, energy and activity that affect how a person functions.

MedlinePlus notes that most people feel sad or irritable from time to time, but a mood disorder affects a person's everyday emotional state. The National Institute of Mental Health (NIMH) describes bipolar disorder as causing clear shifts in mood, energy, activity levels and concentration. For a side-by-side comparison, see mood swings versus bipolar disorder.

What are the main types of bipolar disorder?

The main types are bipolar I, bipolar II and cyclothymic disorder. They differ in how intense and how long the high periods are.

• Bipolar I. NIMH defines it by manic episodes that last at least 7 days, or mania severe enough to need hospital care. Depressive episodes usually occur too.
• Bipolar II. A pattern of depressive episodes and hypomanic episodes, which are milder than full mania.
• Cyclothymic disorder. Recurring hypomanic and depressive symptoms that are not intense or long enough to count as full episodes.

MedlinePlus notes that bipolar disorder was formerly called manic depression. Our guide to types of bipolar disorder covers each in more depth.

What do manic and hypomanic episodes look like?

Manic and hypomanic episodes look like a sustained rise in energy and activity, often with less need for sleep, racing thoughts and impulsive choices.

NIMH lists signs of mania such as feeling very up, high, elated, extremely irritable or touchy, racing thoughts and a decreased need for sleep. Other signs can include talking fast, taking on many projects at once, spending sprees and risky decisions. Hypomania can feel good. NIMH notes that hypomanic episodes may make a person feel very good and productive, even when family and friends notice the change. That is one reason the highs are easy to overlook.

What do bipolar depressive episodes look like?

Bipolar depressive episodes look much like other depression: low mood, slowed thinking and movement, trouble concentrating and loss of interest.

NIMH lists signs such as feeling very down, sad or anxious, feeling slowed down, sleeping too much or too little, and feeling hopeless or thinking about death or suicide. For many people, depressive episodes last longer and feel more disabling than the highs. Because depression is what brings many people to care, NIMH notes that bipolar II is often missed when people seek help mainly for low mood. See bipolar 2 versus depression.

What are the less obvious faces of bipolar disorder?

The less obvious bipolar disorder symptoms include irritability rather than euphoria, mixed episodes and changes that show up mainly in sleep, work or relationships.

• Irritability. Highs can look like anger, impatience or arguments rather than happiness.
• Mixed episodes. NIMH explains that a mixed episode has both manic and depressive symptoms, such as feeling hopeless while also restless and wired.
• Sleep changes. Feeling rested after very little sleep can be an early warning sign.
• Work and money. Sudden job changes, big purchases or new ventures started and dropped.
• Substance use. Some people use alcohol or drugs during episodes, and NIMH notes some substances can mimic or worsen mood symptoms.

Example: a person might describe a two-week stretch of sleeping four hours a night, starting three side businesses and arguing with coworkers, followed by a month of barely getting out of bed. Neither period alone may look alarming to friends. Together, they form the pattern that clinicians look for when they assess bipolar disorder symptoms.

Who gets bipolar disorder and why?

Bipolar disorder most often begins in the late teens or early adult years, and it tends to run in families, though no single cause has been identified.

NIMH reports that symptoms most often start during late adolescence or early adulthood. MedlinePlus states that the exact cause is unknown, and that genetics, brain structure and function, and environment may all play a role. Risk is higher for people with a parent or sibling who has the condition.

Having a relative with bipolar disorder does not mean you will develop it, and many people with the condition have no known family history. What matters most is noticing a pattern of episodes over time. Bipolar disorder symptoms that first appear in the teen years are sometimes mistaken for ordinary adolescent moodiness, which is one reason careful, longer-term observation helps.

How is bipolar disorder diagnosed? A step-by-step guide

Diagnosis involves a careful history, a look at patterns over time and ruling out other causes. There is no single blood test for it.

1. Track your moods. NIMH suggests a mood chart or journal to spot patterns in mood, sleep and energy.
2. Get a medical check. A provider may order medical testing to rule out other illnesses.
3. Book a psychiatric evaluation. A clinician will ask about lifetime highs and lows, not just current symptoms.
4. Bring family history. Mention relatives with mood disorders or substance use.
5. Invite input from someone close. With your permission, a partner or relative can describe changes you may not notice.
6. Discuss a treatment plan. Ask about therapy, medication and routines.

What should I tell a clinician? A checklist

Tell a clinician about both the lows and the highs, even if the highs felt good. Specific examples help most.

• Times you needed much less sleep but did not feel tired.
• Periods of unusual energy, confidence or talkativeness.
• Spending, risky choices or projects you later regretted.
• How long highs and lows lasted.
• Any mood changes after starting an antidepressant or bright light therapy.
• Alcohol, drug and supplement use.
• Relatives with bipolar disorder, depression or suicide.

The light therapy question matters because a scientific review lists rare hypomanic or manic episodes among the side effects of light therapy.

How is bipolar disorder treated and managed?

Bipolar disorder is usually managed with a combination of medication, therapy and steady routines over the long term.

NIMH notes that bipolar disorder usually requires lifelong treatment, even during periods when a person feels well. Medication classes such as mood stabilizers are commonly part of care, and decisions belong with a prescriber. NIMH recommends keeping a steady routine for eating, sleeping and exercise and avoiding drugs and alcohol. Family members can help by learning triggers and supporting appointments.

Therapy can help people recognize early warning signs, plan for stressful periods and repair strain in relationships after an episode. A written plan that lists early signs, helpful steps and who to call can make it easier to act quickly. For more on treatment approaches, many people find it useful to review options with both a therapist and a prescriber.

When should I get help right away?

Get help right away for thoughts of suicide, severe mania or behavior that puts someone at risk.

• Thoughts of death or suicide: call or text 988.
• Several nights with little or no sleep and escalating energy.
• Seeing or hearing things others do not, or holding beliefs others find impossible.
• Dangerous driving, spending or other risky behavior.
• Any immediate danger to self or others: call 911.

What should Texans know about bipolar care?

Texans can often combine in-person and telehealth care for bipolar disorder, which helps with regular follow-up over the long term.

The U.S. Department of Health and Human Services describes hybrid care, in which you and your provider decide together when to use telehealth or in-person visits. Lyte Psychiatry offers telehealth visits to patients who are physically located in Texas at the time of the visit. Telehealth rules vary by state.
