Common Signs and Symptoms of Bipolar Disorder

Review commonly discussed signs of Bipolar Disorder and why symptoms should be considered in context. Get clear information from Tinka Health Services for.

Bipolar disorder can cause noticeable changes in mood, energy, sleep, activity, thinking, communication, judgment, and daily functioning. These changes occur during periods called mood episodes and are usually more intense, sustained, and disruptive than ordinary emotional ups and downs.

A person with bipolar disorder may experience manic episodes, hypomanic episodes, depressive episodes, or episodes with mixed features. Symptoms vary widely. One person may become highly energetic and euphoric, while another becomes intensely irritable, restless, or agitated. Depressive symptoms may involve sadness, but they can also appear as emotional numbness, exhaustion, withdrawal, hopelessness, or loss of interest.

The presence of one symptom does not mean that someone has bipolar disorder. Many symptoms associated with bipolar disorder can also occur with anxiety, attention-deficit/hyperactivity disorder, trauma-related conditions, substance use, sleep deprivation, medical conditions, medication effects, or ordinary life stress.

What makes bipolar symptoms clinically important is the overall pattern: how many symptoms occur together, how long they last, how different they are from the person’s usual behavior, and how much they affect daily life.

Bipolar mood episodes involve significant changes in mood, energy, activity, concentration, and functioning that may continue for days or weeks and may be noticeable to other people.

This page focuses on common signs and symptoms. For a broader explanation of the condition, visit What Is Bipolar Disorder?

Understanding Symptoms as a Pattern

Bipolar disorder is not identified through one isolated behavior.

A person may occasionally stay up late, feel excited, speak quickly, spend too much money, or become discouraged without having bipolar disorder. The concern becomes greater when several changes happen at the same time and represent a significant departure from the person’s usual functioning.

Healthcare professionals look at factors such as:

The type of mood change
The number of symptoms occurring together
How long the changes continue
Whether symptoms occur most of the day
Whether similar episodes have happened before
The person’s usual sleep and energy pattern
Changes noticed by family members or close friends
The effect on work, school, relationships, finances, or safety
Medication, alcohol, cannabis, stimulant, and other substance use
Medical conditions that may contribute to the symptoms

During a mood episode, symptoms may affect several areas at once. For example, reduced sleep may occur together with increased energy, rapid speech, unusual confidence, impulsive spending, and irritability.

This combined pattern is more informative than reduced sleep alone.

Common Signs of a Manic Episode

Mania is a period of abnormally elevated, expansive, or irritable mood accompanied by increased energy or activity. Symptoms are severe enough to cause major impairment, require hospitalization, create serious safety concerns, or include psychotic symptoms in some cases.

Mania does not always look happy or cheerful. A person may appear excited and enthusiastic, but they may also become impatient, argumentative, agitated, hostile, or difficult to redirect.

Common manic symptoms include elevated or irritable mood, reduced need for sleep, racing thoughts, rapid speech, distractibility, exaggerated confidence, increased activity, and risky behavior.

Unusually Elevated or Euphoric Mood

A person experiencing mania may feel extremely happy, powerful, excited, or emotionally “high.”

The mood may appear out of proportion to the person’s situation. They may describe feeling better than ever, having unlimited potential, or being capable of accomplishing extraordinary things.

This elevated mood may involve:

Intense enthusiasm
Excessive optimism
Unusually strong confidence
Frequent joking or laughing
Excitement that is difficult to interrupt
A belief that failure is impossible
Feeling specially chosen, gifted, or important

The person may not recognize the mood as unusual because it feels positive from the inside.

Severe Irritability or Agitation

Mania may present primarily as irritability rather than happiness.

A person may become:

Easily frustrated
Argumentative
Impatient with other people
Angry when questioned
Sensitive to disagreement
Intolerant of delays
Verbally aggressive
Restless or unable to remain still

Family members may notice that ordinary conversations quickly become confrontational. A normally patient person may react strongly to minor inconveniences or view reasonable concerns as attempts to control them.

Irritability becomes more concerning when it appears alongside reduced sleep, increased energy, rapid speech, impulsivity, or unrealistic plans.

Reduced Need for Sleep

A reduced need for sleep is an important sign of mania or hypomania.

The person may sleep only two or three hours and still feel energetic, alert, and ready to continue working or socializing. They may say they no longer need much sleep or that resting would waste valuable time.

This differs from ordinary insomnia. Someone with insomnia usually wants to sleep and feels tired because they cannot. During an elevated bipolar episode, the person may sleep very little without initially feeling fatigued.

Possible signs include:

Staying awake most of the night
Beginning projects in the early morning hours
Calling or messaging people overnight
Cleaning, shopping, driving, or working while others are asleep
Sleeping briefly and waking with immediate energy
Becoming irritated when encouraged to rest

A major change in sleep combined with increased activity deserves prompt attention.

Increased Energy and Activity

Mania can produce a strong drive to remain active.

The person may:

Begin many projects at once
Work for unusually long periods
Rearrange or renovate the home
Exercise excessively
Attend numerous social events
Travel unexpectedly
Start a business without preparation
Become involved in several new causes or organizations
Take on responsibilities beyond their available time or resources

Activity may increase without becoming more organized. The person may begin many tasks but finish very few because attention keeps shifting to new ideas.

Rapid or Pressured Speech

Speech may become unusually fast, loud, continuous, or difficult to interrupt.

A person may:

Talk for long periods without pausing
Interrupt other people repeatedly
Move quickly from one subject to another
Speak more loudly than usual
Feel an urgent need to express every idea
Become frustrated when others cannot follow
Send unusually long or frequent messages

Pressured speech may feel as though the words are being pushed out faster than the listener can process them.

Racing Thoughts

A person experiencing mania may describe their mind as moving extremely fast.

Thoughts may seem to jump from one idea to another. The person may feel creative or mentally powerful, but the speed of thinking can make concentration and organized decision-making difficult.

Possible descriptions include:

“My mind will not slow down.”
“I have hundreds of ideas at once.”
“Everything feels connected.”
“I cannot explain my thoughts quickly enough.”
“I need to act before the opportunity disappears.”

Racing thoughts can also occur with anxiety, stimulant use, sleep deprivation, and other conditions. Their meaning depends on the wider symptom pattern.

Distractibility

Attention may shift rapidly toward noises, people, messages, visual details, or new ideas.

For example, someone may begin discussing a work problem, notice a notification, start planning a trip, remember a business idea, and then abandon the original conversation.

Distractibility may lead to:

Incomplete tasks
Missed details
Frequent topic changes
Difficulty following plans
Unsafe driving
Poor performance despite increased activity
Frustration from coworkers or family members

Inflated Self-Esteem or Grandiosity

Confidence may become much stronger than the person’s abilities, experience, or circumstances reasonably support.

The person may believe they have exceptional talent, authority, wealth, influence, intelligence, spiritual power, or professional ability.

Examples may include believing that they can:

Become extremely wealthy within days
Lead an organization without experience
Complete months of work overnight
Influence powerful public figures
Solve a major scientific or social problem alone
Perform professionally in an unfamiliar field
Function indefinitely without sleep

In severe mania, grandiose beliefs may become delusional, meaning the person holds them firmly despite clear evidence that they are not true.

Impulsive or Risky Behavior

Mania can significantly affect judgment and awareness of consequences.

Risky behavior may include:

Excessive spending
Giving away money or possessions
Opening multiple credit accounts
Gambling
Making poorly researched investments
Driving at unsafe speeds
Quitting a job suddenly
Making major business commitments
Engaging in unsafe sexual behavior
Using alcohol or substances heavily
Traveling without preparation
Confronting strangers or authorities
Entering dangerous environments

The person may believe the behavior is reasonable and may resist efforts to slow down or review the decision.

Increased Sexual Interest or Disinhibition

Some people experience a significant increase in sexual interest during mania or hypomania.

This may involve:

Uncharacteristic flirting
Multiple sexual partners
Unsafe sexual behavior
Contacting former partners
Sharing intimate information publicly
Ignoring relationship boundaries
Spending money on sexual activity
Making decisions that later cause regret or relationship conflict

Increased sexual behavior should be understood in the context of other mood and behavioral changes. It is not by itself proof of bipolar disorder.

Poor Insight

During mania, a person may have difficulty recognizing that their behavior has changed or become unsafe.

They may feel healthier, more productive, or more capable than usual and may believe that other people are jealous, negative, controlling, or unable to understand their plans.

Poor insight can make it difficult to encourage evaluation. Family members may recognize the episode before the individual does.

Common Signs of Hypomania

Hypomania involves many of the same types of symptoms as mania, but the symptoms are less severe.

The change is still noticeable and different from the person’s usual behavior, but it does not cause the level of marked impairment associated with mania. Hypomania does not include psychosis and is not severe enough by itself to require hospitalization.

Hypomania can easily be missed because it may feel productive or enjoyable. The person may describe feeling energized, confident, social, creative, or highly motivated.

Possible signs include:

Needing less sleep
Talking more than usual
Feeling unusually confident
Becoming more sociable
Taking on additional responsibilities
Starting several projects
Spending more money
Becoming more easily distracted
Showing increased sexual interest
Becoming unusually impatient or irritable
Working for extended periods
Making faster decisions
Feeling mentally sharper or more creative

Hypomania may appear beneficial at first, but the activity may become unsustainable. The person may overcommit, neglect routine responsibilities, create conflict, or make decisions that have consequences later.

Family members and close friends may notice the change even when the person believes nothing is wrong. Hypomanic periods may also be followed by depressive episodes.

For a deeper explanation, visit Hypomanic Episodes.

Common Signs of Bipolar Depression

A bipolar depressive episode may involve sadness, but depression can affect nearly every area of functioning.

The person may experience changes in mood, motivation, sleep, appetite, concentration, movement, energy, self-worth, and interest in daily life.

Bipolar depression can resemble major depressive disorder. This is one reason some people are initially treated for depression before previous hypomanic or manic symptoms are recognized.

Persistent Sadness, Emptiness, or Hopelessness

A person may feel deeply sad, emotionally empty, discouraged, or unable to believe that circumstances can improve.

They may describe feeling:

Heavy
Numb
Trapped
Defeated
Disconnected
Worthless
Emotionally exhausted

Not everyone appears tearful. Some people become quiet, irritable, emotionally distant, or unable to describe what they are feeling.

Loss of Interest or Pleasure

Activities that once felt enjoyable or meaningful may no longer provide satisfaction.

A person may lose interest in:

Spending time with friends
Sexual intimacy
Hobbies
Work
School
Exercise
Music
Food
Family activities
Religious or community participation

This loss of interest is sometimes called anhedonia.

The person may continue performing certain activities out of obligation but feel emotionally disconnected from them.

Low Energy and Fatigue

Depression may produce profound physical and mental exhaustion.

Ordinary activities may feel unusually demanding. Showering, preparing a meal, answering a message, or leaving the house may require significant effort.

The person may:

Remain in bed for long periods
Move more slowly
Need frequent breaks
Feel tired after sleeping
Avoid tasks because they seem overwhelming
Struggle to begin the day
Stop participating in household responsibilities

Low energy is not necessarily laziness or lack of concern. It can be a significant symptom of depression.

Changes in Sleep

Bipolar depression may involve sleeping too much, sleeping too little, or experiencing poor-quality sleep.

Possible changes include:

Difficulty falling asleep
Waking during the night
Waking earlier than intended
Sleeping late into the day
Taking frequent naps
Remaining in bed without feeling rested
Reversing the normal day-and-night schedule

Sleep changes are most meaningful when they represent a clear difference from the person’s usual pattern.

Changes in Appetite or Weight

A person may eat much less or much more than usual.

They may:

Lose interest in food
Skip meals
Eat only because someone reminds them
Crave certain foods
Eat for comfort
Experience noticeable weight change
Lack the energy to shop or prepare meals

Appetite changes can also be caused by medical conditions, medication effects, stress, or other mental health concerns.

Difficulty Concentrating or Making Decisions

Depression can slow thinking and make ordinary decisions feel difficult.

A person may struggle to:

Read and understand information
Remember instructions
Follow a conversation
Complete paperwork
Respond to email
Make routine choices
Organize tasks
Meet deadlines
Manage finances

Someone who usually works efficiently may spend hours trying to complete a simple assignment.

Feelings of Worthlessness or Excessive Guilt

The person may become highly critical of themselves and focus intensely on past mistakes.

They may believe:

They are a burden
They have disappointed everyone
They are failing at work or parenting
They do not deserve support
Their situation cannot be repaired
Other people would be better without them

These beliefs may not reflect the person’s actual circumstances, but they can feel completely convincing during depression.

Social Withdrawal

Depression may lead someone to stop answering calls, cancel plans, avoid family members, or remain isolated.

Withdrawal may occur because the person:

Has little energy
Feels ashamed
Does not want to burden others
Cannot follow conversations
Has lost interest in social activity
Believes others do not want them around

Friends may interpret withdrawal as rejection when it is actually part of a depressive episode.

Changes in Movement or Restlessness

Depression can affect physical movement.

Some people move and speak more slowly. Others feel restless, unable to sit comfortably, or driven by internal agitation.

Family members may notice:

Slower walking
Reduced facial expression
Long pauses before answering
Remaining in one position for long periods
Pacing
Hand-wringing
Repeatedly getting up and sitting down

Thoughts of Death or Suicide

Some people experiencing bipolar depression have thoughts about death, self-harm, or suicide.

Warning signs may include:

Saying life is not worth living
Expressing that others would be better without them
Talking about wanting to disappear
Searching for methods of suicide
Gathering medications or weapons
Giving away belongings
Writing goodbye messages
Taking dangerous risks
Suddenly appearing calm after severe distress

Suicidal thoughts require serious attention. Call or text 988 in the United States for crisis support. Call 911 or go to the nearest emergency room when there is immediate danger, a suicide attempt has occurred, or the person has a plan and access to means.

Signs of an Episode With Mixed Features

Bipolar symptoms do not always appear as a clearly separated emotional high or low.

An episode with mixed features includes symptoms associated with depression and symptoms associated with mania or hypomania during the same period.

A person may feel depressed, hopeless, or emotionally distressed while also experiencing:

Racing thoughts
Increased energy
Rapid speech
Irritability
Agitation
Reduced need for sleep
Impulsive behavior
Restlessness
Increased activity

For example, someone may feel worthless and hopeless while pacing, sleeping very little, speaking rapidly, and acting impulsively.

Mixed symptoms may be especially difficult to recognize because the person may appear energized without feeling happy. Depressive thoughts combined with agitation or impulsivity can create serious safety concerns.

The American Psychiatric Association recognizes that depressive and manic symptoms may occur together during episodes with mixed features.

Prompt professional evaluation is important when someone experiences severe depression together with agitation, racing thoughts, reduced sleep, or increased activity.

Psychotic Symptoms in Bipolar Disorder

Some people experience psychosis during severe manic or depressive episodes.

Psychosis may involve hallucinations, delusions, severe paranoia, or difficulty distinguishing what is real.

Possible signs include:

Hearing voices other people do not hear
Seeing things other people do not see
Believing ordinary events contain special messages
Believing someone is watching or controlling them
Believing they have extraordinary powers or authority
Becoming intensely suspicious of trusted people
Speaking in a severely disorganized way
Acting on beliefs that place someone in danger

Psychotic symptoms may be consistent with the mood episode. During mania, a person may believe they possess extraordinary wealth, power, fame, or spiritual importance. During depression, they may believe they have committed an unforgivable act or caused a disaster.

Psychosis can also occur with other psychiatric, neurological, medical, medication-related, or substance-related conditions. It requires urgent professional assessment.

Severe mania may include hallucinations or delusions and can lead to unsafe decisions or hospitalization.

Call 911 or go to the nearest emergency room when psychotic symptoms are accompanied by threats, dangerous behavior, severe confusion, inability to care for basic needs, or risk of harm.

Behavioral Signs Others May Notice

Bipolar symptoms may be easier for family members, partners, friends, or coworkers to recognize because they can compare the person’s current behavior with their usual pattern.

Others may notice:

A dramatic change in sleep
Unusually rapid or loud speech
Constant activity
Sudden spending
Increased irritability
Frequent arguments
Many unfinished projects
Uncharacteristic sexual behavior
Risky driving
Increased alcohol or substance use
Social withdrawal
Missed work or school
Declining personal hygiene
Unopened mail or unpaid bills
Messages sent at unusual hours
Unrealistic plans
Severe hopelessness
Confusing or paranoid statements

A family member may say, “You do not seem like yourself,” before the individual recognizes the change.

Observations from trusted people can be helpful during an evaluation, particularly when mania or hypomania has affected insight.

How Symptoms Can Affect Daily Life

Bipolar symptoms may influence:

Work performance
Academic responsibilities
Parenting
Relationships
Household routines
Money management
Driving
Physical health
Social activity
Personal hygiene
Appointment attendance
Medication routines

During an elevated episode, the person may appear highly productive but make disorganized or risky decisions. During depression, the person may struggle to begin basic tasks.

The effect may be different across settings. Someone may continue performing well at work while experiencing severe relationship or financial problems. Another person may maintain household routines but struggle internally with hopelessness and exhaustion.

Early Warning Signs of an Approaching Mood Episode

Some people notice recurring changes before a full mood episode develops.

Possible early warning signs of mania or hypomania include:

Sleeping less
Feeling unusually energized
Talking more
Becoming more social
Increasing caffeine or substance use
Starting new projects
Spending more
Becoming more impatient
Feeling unusually confident
Sending frequent messages
Abandoning regular routines

Possible early warning signs of depression include:

Sleeping more or less
Withdrawing socially
Losing interest in activities
Feeling physically heavy
Delaying responsibilities
Becoming more self-critical
Eating differently
Missing appointments
Struggling to concentrate
Feeling increasingly hopeless

Early warning signs vary by person. A written mood plan may help identify the person’s usual pattern and clarify when to contact a healthcare professional.

Symptoms in Children and Teenagers

Bipolar symptoms can occur in younger people, but evaluation can be complicated because normal development, attention difficulties, trauma, anxiety, substance use, sleep disruption, and family stress may produce overlapping behaviors.

Possible symptoms may include intense mood changes accompanied by significant changes in sleep, energy, activity, thoughts, or behavior.

Parents may notice periods of:

Unusually high energy
Very little sleep without tiredness
Rapid speech
Extreme confidence
Severe irritability
Reckless behavior
Increased activity
Major decline in school performance
Withdrawal
Persistent sadness
Loss of interest
Self-harm or suicidal statements

Frequent temper outbursts alone do not establish bipolar disorder. The timing, duration, associated symptoms, developmental history, and level of impairment all matter.

Any child or teenager expressing suicidal thoughts, experiencing psychosis, or behaving dangerously needs immediate professional support.

Visit Bipolar Disorder in Children and Teens for a focused discussion.

Symptoms That May Be Mistaken for Another Condition

Several conditions can cause symptoms that resemble bipolar disorder.

Bipolar Disorder and ADHD

Both conditions may involve distractibility, rapid speech, restlessness, impulsivity, and difficulty completing tasks.

A key difference clinicians consider is whether symptoms are ongoing or occur in distinct episodes with changes in mood, sleep, energy, and functioning.

A person can also have both conditions.

Bipolar Disorder and Anxiety

Anxiety may cause racing thoughts, insomnia, restlessness, irritability, and difficulty concentrating.

In anxiety, the person may feel tired and distressed by the inability to sleep. During mania or hypomania, the person may need little sleep and still feel energized.

Bipolar Disorder and Trauma-Related Symptoms

Trauma-related conditions may involve emotional reactivity, sleep problems, irritability, avoidance, impulsivity, and periods of intense distress.

A careful evaluation considers trauma history, triggers, episode duration, and associated changes in energy and activity.

Bipolar Disorder and Substance Use

Stimulants, cannabis, alcohol, recreational substances, medication effects, and withdrawal can influence sleep, mood, perception, energy, and judgment.

Accurate information about substance use helps clinicians determine whether symptoms represent a primary mood disorder, a substance-related condition, or both.

Bipolar Disorder and Medical Conditions

Thyroid disorders, neurological conditions, sleep disorders, hormonal changes, medication reactions, and other medical issues can affect mood and behavior.

Professional evaluation may include medical review or testing when clinically appropriate.

Common Misconceptions About Bipolar Symptoms

“Bipolar disorder means moods change every few minutes.”

Bipolar mood episodes usually involve sustained changes lasting days or longer. Brief emotional reactions may have many other explanations.

“Mania always looks happy.”

Mania may involve severe irritability, agitation, hostility, or aggression rather than euphoria.

“A productive person cannot be hypomanic.”

Hypomania may initially increase productivity, but the activity may become disorganized, excessive, or unsustainable.

“Depression always means crying.”

Depression may look like numbness, withdrawal, exhaustion, irritability, poor concentration, or loss of interest.

“One symptom confirms bipolar disorder.”

Diagnosis depends on the complete pattern, duration, severity, history, and effect on functioning.

“People always recognize their own manic symptoms.”

Mania may reduce insight. The person may believe they are functioning exceptionally well while others observe concerning changes.

“Everyone with bipolar disorder has the same symptoms.”

The type, severity, frequency, and combination of symptoms differ from one person to another.

When to Consider Getting Help

Consider a professional psychiatric evaluation when mood, sleep, energy, thinking, or behavioral changes:

Continue for several days or longer
Recur in noticeable episodes
Are significantly different from the person’s usual behavior
Affect work, school, parenting, or relationships
Cause financial, legal, or occupational problems
Lead to unsafe driving, sexual behavior, or substance use
Prevent basic self-care
Cause family members to express serious concern
Include psychotic symptoms
Involve suicidal thoughts or behavior

A person does not need to experience every symptom before seeking help.

Professional evaluation can help determine whether symptoms may be related to bipolar disorder, another mental health condition, medication or substance effects, sleep disruption, or a medical condition.

Call or text 988 in the United States for mental health or suicide crisis support. Call 911 or go to the nearest emergency room when someone may harm themselves or another person, has attempted suicide, is experiencing dangerous psychosis, or cannot remain safe.

Key Takeaway

Common signs and symptoms of bipolar disorder include significant changes in mood, sleep, energy, activity, speech, thinking, concentration, confidence, judgment, and daily functioning.

Manic and hypomanic symptoms may include reduced need for sleep, increased energy, rapid speech, racing thoughts, distractibility, unusual confidence, irritability, impulsivity, and risky behavior.

Depressive symptoms may include persistent sadness or emptiness, loss of interest, fatigue, changes in sleep or appetite, difficulty concentrating, social withdrawal, feelings of worthlessness, and thoughts of death or suicide.

Some people experience depressive and elevated symptoms at the same time. Severe episodes may include psychosis.
