What Is Mania Disorder? Signs of a Manic Episode, Causes and Treatment

Someone who hasn’t slept for days yet feels full of energy, talks non-stop, makes grand plans, spends money they don’t have and gets furious when anyone questions them. To family members, it can look like a “good mood” that has gone too far, or like deliberate bad behaviour. It is often mania, a medical condition that needs treatment.This guide explains what mania is, how it differs from hypomania and bipolar disorder, the signs, causes, how it is diagnosed and treated, how to help someone, and when to get urgent help. It is general information, not medical advice or a diagnosis.

In short

• Mania is a period of abnormally high, expansive or irritable mood with unusually high energy, lasting at least a week (or any length if hospital care is needed).
• “Mania disorder” is usually a lay term. Clinically, mania is an episode most often seen in bipolar I disorder.
• Signs include little need for sleep, racing thoughts, fast speech, inflated self-confidence and risky behaviour. In severe cases, there may be delusions or hallucinations.
• It is treatable. Mood-stabilising medicines, therapy, routine and family support help many people live well.
• Severe mania can be an emergency. If someone is unsafe, call 112.

What is mania?

Mania is a state of abnormally elevated, expansive or irritable mood combined with increased energy or activity. It is far beyond ordinary happiness or being “in a good mood.” In the DSM-5-TR, a manic episode lasts at least one week, present most of the day, nearly every day, or any length if the person needs hospital care. It is a key feature of bipolar I disorder, a condition recognised in the DSM-5-TR and the WHO’s ICD-11, in which a person has episodes of mania and often, though not always, episodes of depression.The World Health Organization estimates that around 40 million people worldwide live with bipolar disorder. It most often begins in the late teens or early adulthood.

Signs and symptoms of mania

Area	What you may notice
Mood	Unusually elated, “high” or euphoric, or very irritable and easily angered. Mood is clearly different from the person’s usual self.
Energy and sleep	Greatly reduced need for sleep, such as feeling rested after two or three hours, with no tiredness. Restlessness and constant activity.
Thoughts	Racing thoughts, jumping from idea to idea, being easily distracted, grand ideas or plans
Speech	Talking very fast, loudly and a lot, and hard to interrupt (“pressured speech”)
Self-image	Inflated self-esteem or a belief in having special powers, talents, wealth or importance
Behaviour	Risky or impulsive choices such as overspending, reckless driving, risky sex, gambling, sudden business or travel plans, quitting jobs
Severe cases	Delusions (for example, believing you are a famous figure or have a divine mission) and hallucinations, known as psychotic features, along with aggression or danger to self or others

For a diagnosis, mood is elevated or irritable plus at least three of these other changes (four if the mood is only irritable), together causing serious problems in work, relationships or safety, or requiring hospital care.

Mania, hypomania and bipolar disorder

Term	What it means
Mania	A severe episode of elevated or irritable mood lasting at least a week (or less if hospitalised), causing marked problems. It may include psychosis.
Hypomania	A milder form lasting at least four days. The person is clearly more energetic and talkative, but functioning isn’t seriously impaired, there is no psychosis and hospital care is not needed.
Bipolar I disorder	At least one manic episode, usually with depressive episodes
Bipolar II disorder	At least one hypomanic episode and one major depressive episode, but no full mania
Mixed features	Symptoms of mania and depression at the same time, such as agitation, racing thoughts and hopelessness. It carries a higher risk of suicide.

Many people with bipolar disorder spend more time in depression than in mania. For more on depression, see is depression a mental disorder and have there been times when you felt depressed or hopeless.

Is it mania, or something else?

Possibility	How it differs
Normal happiness or high energy	Matches a cause, doesn’t last for days with no sleep, and doesn’t lead to risky or harmful choices
Drug- or alcohol-induced “highs”	Stimulants, cannabis, alcohol and some other substances can cause manic-like states. These can look identical, so substance use needs to be assessed.
Medical causes	An overactive thyroid, steroid medicines, brain injury or other conditions can cause manic-like symptoms
ADHD	Restlessness and impulsivity are lifelong rather than episodic. See what is ADHD and its symptoms
Schizophrenia and other psychoses	Psychosis occurs without the clear mood episodes of mania. See schizophrenia
Anxiety or agitation	Worry and restlessness without elevated mood, grandiosity and reduced need for sleep

What causes mania?

There is no single cause. Bipolar disorder and mania reflect a mix of:

• Genetics: having a close relative with bipolar disorder raises the risk significantly
• Brain function and chemistry, including differences in mood-regulating systems
• Sleep disruption: losing sleep can trigger mania in vulnerable people, for example from night shifts, travel or exam stress
• Major stress or life events, good or bad
• Substance use: alcohol, cannabis, stimulants and other drugs
• Some medicines, such as steroids and, in some people with bipolar disorder, antidepressants taken without a mood stabiliser
• Medical conditions, such as thyroid disease

Mania is not caused by bad parenting, weak character or “too much happiness.”

How is mania diagnosed?

A psychiatrist usually makes the diagnosis by talking with the person and, ideally, a family member, and reviewing the history of mood episodes. There is no blood test or scan for bipolar disorder, though tests may rule out other causes. The assessment typically includes:

1. A detailed history of mood, energy, sleep and behaviour, including past episodes of high and low mood
2. Information from family, who often notice changes first
3. Questions about alcohol, drugs, medicines and medical conditions
4. Physical examination and blood tests, such as thyroid function
5. Screening for depression, anxiety, psychosis and risk of harm
6. Comparison with the DSM-5-TR or ICD-11 criteria

If you’d like a private starting point, our confidential self-screening is available for mental health concerns. It is not a diagnosis.

How is mania treated?

Approach	What it does
Mood stabilisers	Medicines such as lithium and certain anticonvulsants help control mania and prevent future episodes. Some need regular blood tests.
Antipsychotic medicines	Often used for acute mania and for psychotic symptoms, and sometimes long term
Short-term calming medicines	May be used briefly during acute episodes, under medical supervision
Hospital care	Sometimes needed for severe mania to keep the person safe and start treatment
Psychoeducation and therapy	Learning about the illness, early warning signs and triggers. Therapies include cognitive behavioural therapy, interpersonal and social rhythm therapy and family-focused therapy. See our schools of therapy.
Routine and sleep	Regular sleep, meals and daily rhythms help prevent episodes. See types of sleep disorders and how to stay mentally healthy
Avoiding alcohol and drugs	Substances can trigger episodes and interfere with treatment
Treating co-occurring conditions	Addresses anxiety, substance use and physical health alongside bipolar disorder

All medicines must be prescribed and monitored by a psychiatrist. Don’t stop or change them suddenly, even when you feel well, because stopping is a common cause of relapse. Treatment is usually long term, and with it many people live stable, productive lives.

A wellness plan for staying well

Many people with bipolar disorder find a written plan helpful, made when they are well and shared with trusted family and the treating doctor.

• Know your early warning signs, such as needing less sleep, feeling unusually energised, talking faster or starting big plans
• Protect sleep and keep a regular routine
• Take medicines as prescribed, and keep follow-up appointments and blood tests
• Avoid alcohol, cannabis and other drugs
• Agree on money safeguards, such as lower limits on cards, joint approval for large transfers and a delay before big purchases
• Name who to call, and what you want the family to do if an episode starts
• Consider an advance directive. India’s Mental Healthcare Act, 2017 allows people to state in advance how they wish to be treated and to name a nominated representative

How to help someone who may be in a manic episode

Helpful	Not helpful
Stay calm and speak slowly and simply	Arguing with grand ideas or shouting
Reduce stimulation: a quiet, calm place with fewer people	Crowding, teasing or provoking them
Encourage sleep and rest	Joining in with risky plans or “going along” with them
Protect finances, for example by securing cards and large sums, where you can do so safely	Handing over money for impulsive projects
Encourage a doctor’s visit, and offer to go with them	Waiting for “a crisis,” or relying only on rituals
Avoid alcohol and drugs in the home	Offering alcohol to “calm them down”
Ask about safety, including thoughts of self-harm	Leaving someone at risk alone

A person in mania may not believe anything is wrong, and may be angry about being asked to see a doctor. This lack of insight is part of the condition, not a personal failing. Stay patient, and involve a professional.

Mania and substance use

Bipolar disorder and substance use often occur together. Some people drink or use drugs to cope with highs and lows, and alcohol, cannabis and stimulants can trigger or worsen manic episodes and make medicines less effective. Substance-induced mania can look like bipolar mania, so assessment matters. When both are present, treating them together gives the best results. See dual diagnosis, how to come out of addiction and how to detox your body from alcohol. If someone drinks heavily every day, don’t stop suddenly without medical advice, as withdrawal can be dangerous.

Practical tips for India

• “High spirits” or “bad behaviour.” Mania is often mistaken for being very happy, wilful or misbehaving. When changes are extreme and out of character, ask for a medical check.
• Delay and rituals. Some families first seek spiritual or ritual remedies. Faith can comfort, but early medical treatment shortens episodes and protects relationships and finances.
• Stigma and “log kya kahenge.” Fear of gossip and its effect on marriage and work keeps many families silent. Confidential services exist, and the Mental Healthcare Act, 2017 protects patients’ rights.
• When the person refuses help. If someone is in serious danger and can’t make decisions during an episode, the Act has provisions for admission and treatment with support from a nominated representative. Ask a psychiatrist or hospital about the process.
• Medication continuity. Medicines like lithium need regular blood tests. Plan follow-up, and ask about availability and cost.
• Free support. Tele-MANAS (14416) offers free tele-mental-health support in India.

When to get help urgently

Call 112 or go to the nearest hospital if the person:

• Talks about ending their life or hurting themselves
• Is aggressive, threatening or putting themselves or others in danger
• Has not slept for days and is becoming confused or exhausted
• Has delusions or hallucinations, or is out of touch with reality
• Is driving recklessly, or behaving in ways that could cause serious harm
• Has stopped medication and is rapidly getting worse

Stay calm, keep a safe distance, and remove anything that could be used to cause harm. In India, Tele-MANAS (14416) is a free national helpline.

Special situations

Teenagers and young adults. The first episode often occurs in these years and may be mistaken for risk-taking, substance use or ADHD. Early assessment matters.After childbirth. Mania or psychosis soon after having a baby is a medical emergency. Seek urgent help.Pregnancy and breastfeeding. Medicines need careful review by a doctor. Don’t stop them without advice.First mania later in life. New-onset mania in older adults is often due to a medical cause or a medicine, so a thorough assessment is needed.Depression after mania. A “crash” into low mood after an episode is common and carries risk. See is depression a mental disorder.

When coping starts to harm

• Drinking, using cannabis or stimulants to feel “even”
• Skipping medicine because the energy feels good
• Staying up all night on projects, social media or gambling
• Taking on loans or credit during highs
• Withdrawing from family and ignoring warning signs

If this sounds familiar, it is a sign to reach out, not a reason for shame.

Looking after yourself as a family member

Living with someone’s mood episodes is exhausting and frightening. You may feel anger, guilt, fear or grief. Talk to a counsellor or trusted friend, share responsibilities, keep your own routines and don’t blame yourself. You can care deeply and still need support.
