Bipolar disorder is a psychological condition that involves extreme changes in mood, behavior, and energy levels, leading to severe disruptions in daily life. However, with effective treatment, one can cope with its symptoms and live a productive life.
What Is Bipolar Disorder?
Bipolar disorder (BD) is a mood disorder, characterized by repeated episodes of depression and unnaturally elevated mood along with changes in levels of energy and activity. These episodes may last from several days to weeks. Also known as bipolar affective disorder, manic depressive illness or manic depression, BD can lead to drastic changes in thinking, judgment, memory, behavior, and sleep.
Although a lot of us have occasional mood swings, people with bipolar disorder experience them in an overwhelming and severe manner. This can disrupt their daily functioning and affect their education, career and personal relationships 1 Grover, S., Nehra, R., & Thakur, A. (2017). Bipolar affective disorder and its impact on various aspects of marital relationship. Industrial psychiatry journal, 26(2), 114–120. https://doi.org/10.4103/ipj.ipj_15_16 . A 2019 study 2 Dome, P., Rihmer, Z., & Gonda, X. (2019). Suicide Risk in Bipolar Disorder: A Brief Review. Medicina (Kaunas, Lithuania), 55(8), 403. https://doi.org/10.3390/medicina55080403 found that the risk of suicide was 10-30 times higher in people with bipolar disorder than in normal people.
Bipolar disorder usually begins during a person’s late teen or early adult years. However, children can also suffer from the condition and it may last a lifetime. Moreover, several comorbid conditions, like anxiety disorders and substance use disorders, are related to BD.
Unfortunately, BD tends to get worse without treatment. Thus, early diagnosis and treatment under a mental health professional is crucial for the effective management of bipolar disorder symptoms.
People with this disorder can be treated effectively with psychological counseling and/or medication depending on the symptoms.
Case Example
Let’s consider the example of Shreya, a 25 year old writer.
People who knew Shreya often described her as “moody”.
There were times when she was highly energetic, and there was nothing that could bring her enthusiasm down. She’d be extremely chatty and overflow with ideas, a lot of which proved to be impractical.
Sometimes, she even talked about becoming the greatest author the world has ever known. On such occasions, Shreya would frequently take up more projects than she could handle.
However, these phases approximately lasted a week. They were mostly followed by days where she was barely productive and hardly spoke to anyone. She would also eat significantly lesser than usual.
In stark contrast to her enthusiastic attitude, Shreya could be heard saying things like, “There is no point to anything, why even work?” and was sometimes even found sleeping at her desk.
These mood fluctuations, that had been a part of Shreya’s life for the past 6 years, were typical of Bipolar I mood disorder.
Symptoms Of Bipolar Disorder
BD is characterized by cognitive deficits and affective instability. Symptoms of bipolar disorder can be different for each patient as the disorder varies widely in frequency, severity, and pattern. Some may experience highs and lows in quick succession while others may experience episodes that last for months or even years.
Listed below are some of the most common manic and depressive symptoms of bipolar disorder:
A. Manic symptoms
Mania or hypomania are characterized by elevated moods. Hypomania is milder in intensity than mania. According to the American Psychiatric Association 3 American Psychological Association. (2015, February 15). Recognizing the signs of bipolar disorder. https://www.apa.org/topics/bipolar-disorder/recognizing , manic episodes in BD usually last at least a week wherein the person is excessively irritable or extremely high spirited. They display at least three of the following symptoms:
- Intrusive, unmanageable racing thoughts and rapidly changing topics or ideas
- Inflated self-esteem or an exaggerated sense of grandiosity
- Reduced need for sleep
- Getting distracted easily
- Increased risky behavior
- Being highly talkative or speaking rapidly and loudly
- Engaging more activities or events at once than can be completed
Mania or hypomania also involves these additional symptoms, including:
- Jumpy or upbeat behavior
- Extremely high levels of energy
- Flawed judgment and poor decision-making
- Psychotic symptoms, including delusions and hallucinations
- Boredom
- Aggression
- Increased libido leading to unprotected sex
- Euphoria
- Incoherent speech
- Exaggerated self-confidence and self-importance
- Spending sprees
- Substance abuse, like alcoholism, drug abuse, etc.
2. Depressive symptoms
According to the American Psychiatric Association 4American Psychological Association. (2015, February 15). Recognizing the signs of bipolar disorder. https://www.apa.org/topics/bipolar-disorder/recognizing , an episode of major depression tends to last for two weeks and involves at least five of the following symptoms:
- Extreme despair or sadness
- Feelings of worthlessness
- Sense of hopelessness and helplessness
- Guilt
- Shame
- Loss of interest in pleasurable activities
- Disturbed sleeping patterns, like insomnia or oversleeping
- Agitation
- Restlessness
- Slurred speech
- Restricted body movement
- Changes in appetite
- Chronic fatigue, exhaustion, or loss of energy
- Poor concentration
- Chronic forgetfulness
- Suicidal ideation
- Self harm

A patient in a depressive episode of bipolar disorder also experiences the following symptoms:
- Uncontrollable weeping
- Weight gain or weight loss
- Indecisiveness or difficulty in making decisions
- Anxiety about insignificant issues
- Irritability
- Listlessness
- Lack of interest in work or school, leading to underperformance
- High sensitivity to sensory stimuli
Experts believe bipolar disorder should be considered as a spectrum of moods. At one end of the spectrum is severe to mild depression, while mania and hypomania are at the other end. Surprisingly, a balanced and normal mood also lies in the middle of the spectrum as well.
Some individuals may experience symptoms of both mania and depression at the same time – this is known as a mixed bipolar state.

Types Of Bipolar Disorder
Depending on the frequency, severity, and presence of symptoms, a person may be diagnosed with different types of bipolar disorder. Here are the major types of bipolar disorders based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5 5 American Psychiatric Association. (2013). Diagnostic and statistical manual of mental disorders (5th ed.) that may be used by doctors to diagnose a patient:
1. Bipolar I disorder (manic or mixed episode)
According to a 2007 study, 6 Keener, M. T., & Phillips, M. L. (2007). Neuroimaging in bipolar disorder: a critical review of current findings. Current psychiatry reports, 9(6), 512–520. https://doi.org/10.1007/s11920-007-0070-2 “bipolar I disorder (BPI) is among the top 10 most debilitating illnesses globally.” It is marked by at least one episode of mania. Periods of major depression or hypomania may also occur before or after the manic episode.
This type of BD can often lead to dramatic mood swings and make the person feel as if they are on top of the world. It may also trigger psychosis. However, periods of normal moods are common between such episodes.
Bipolar I disorder requires that the patient must experience a manic episode for at least 7 days or the episode must be severe enough to necessitate hospitalization. However, the symptoms must not be caused by any other mental conditions, like delusional disorder or schizophrenia.
Studies 7 Bebbington, P., & Ramana, R. (1995). The epidemiology of bipolar affective disorder. Social psychiatry and psychiatric epidemiology, 30(6), 279–292. https://doi.org/10.1007/BF00805795 reveal that lifetime prevalence of bipolar disorder type 1 is around 1% in the general population.
2. Bipolar II disorder (hypomania and depression)
Individuals with this variant of BD experience an episode of major depression which may sustain for two weeks or more, and a period of hypomania which can last up to four days.
It has been observed that bipolar II disorder is more common in female patients than in males 8 Arnold L. M. (2003). Gender differences in bipolar disorder. The Psychiatric clinics of North America, 26(3), 595–620. https://doi.org/10.1016/s0193-953x(03)00036-4 . Contrary to popular belief, this is not a milder version of bipolar I disorder; it is a distinct subtype with its own diagnostic criteria.
Individuals with bipolar II disorder usually do not experience a full-blown manic episode, and depression often dominates their mood 9 Bipolar Disorder. (n.d.). National Institute of Mental Health (NIMH); www.nimh.nih.gov. Retrieved August 26, 2022, from https://www.nimh.nih.gov/health/topics/bipolar-disorder . During a hypomanic episode, a person may feel normal and function effectively, but depressive episodes are characterized by unstable and volatile moods.
The mood shifts of bipolar II disorder are very different from mood disorders caused by other mental conditions or medications. Yet, even though the symptoms of bipolar II disorder are milder, these are often accompanied by a plethora of symptoms linked to depression, anxiety, or substance abuse. This condition generally doesn’t require hospitalization.

3. Cyclothymic disorder (hypomania and mild depression)
Cyclothymia is characterized by less intense and shorter episodes of depression and hypomania. Its symptoms are milder than bipolar I and bipolar II disorders.
People with this condition experience several episodes of hypomania and depression, lasting for at least two years, with brief episodes of normal mood in between lasting less than 8 weeks 10 Bipolar Disorder. (n.d.). National Institute of Mental Health (NIMH); www.nimh.nih.gov. Retrieved August 26, 2022, from https://www.nimh.nih.gov/health/topics/bipolar-disorder .
Nonetheless, most of the time, the symptoms of cyclothymia fail to meet the criteria established for hypomanic or depressive episodes. During this 2–year period, the mood swings sustain for at least 50% of the time, without ceasing for over 2 months.
Although many people with this condition avoid seeking help under the impression that the symptoms are not serious enough, cyclothymia can have severe effects in a person’s relationships, career and quality of life.

4. Bipolar Disorder, “other specified” and “unspecified”
Research shows that there are multiple types of “unspecified” bipolar disorders in which a person does not meet the criteria for either bipolar I, II, or cyclothymia.
But they still experience periods of clinical mood elevation and suffer from health disorders triggered by substance abuse, a psychiatric illness, or a medical condition (such as a stroke, multiple sclerosis, or Cushing’s disease) 11 Duckworth, K. (2017). Bipolar disorder . National Alliance on Mental Illness; www.nami.org. https://www.nami.org/About-Mental-Illness/Mental-Health-Conditions/Bipolar-Disorder#:~:text=Bipolar%20Disorder%2C%20%E2%80%9Cother%20specified%E2%80%9D,clinically%20significant%20abnormal%20mood%20elevation.
Bipolar Disorder Diagnosis
As of now, there is no medical test to diagnose bipolar disorder 12 Gomez-Casati, D., Grisolía, M., & Busi, M. (2016). The significance of Metabolomics in human health. Medical and Health Genomics, 89-100. https://doi.org/10.1016/b978-0-12-420196-5.00007-1 . A mental health professional, such as a psychologist or a psychiatrist, usually takes a detailed history of the person, along with a mental status examination (MSE), and conducts certain psychometric assessments 13 Miller, C. J., Johnson, S. L., & Eisner, L. (2009). Assessment Tools for Adult Bipolar Disorder. Clinical psychology : a publication of the Division of Clinical Psychology of the American Psychological Association, 16(2), 188–201. https://doi.org/10.1111/j.1468-2850.2009.01158.x in order to arrive at a diagnosis. Some of these include :
- Structured Clinical Interview for DSM IV (SCID)
- Schedule for Affective Disorders and Schizophrenia (SADS)
- Mood Disorder Questionnaire, etc.
Read More About Schizophrenia Here
Certain other tests may also be recommended such as a blood test, thyroid level test, protein levels test, substance, and alcohol screening, etc. in order to rule out other causes for the symptoms.
To be diagnosed with BD:
- You must have experienced at least one episode of mania or hypomania.
- For mania, the elevated or irritable mood must persist for at least 7 consecutive days and be experienced almost every day.
- For hypomania, the elevated mood must persist for at least 4 consecutive days and be experienced almost every day.
Diagnosing bipolar disorder accurately and timely can significantly help to manage the condition and improve the prognosis for the patient 14 Culpepper L. (2014). The diagnosis and treatment of bipolar disorder: decision-making in primary care. The primary care companion for CNS disorders, 16(3), PCC.13r01609. https://doi.org/10.4088/PCC.13r01609 However, due to the diversity of symptoms, proper bipolar disorder diagnosis can often be a challenge.
How Common Is Bipolar Disorder?
Bipolar disorder statistics 15 Bipolar disorder | NEJM. (2020, July 1). New England Journal of Medicine. https://www.nejm.org/doi/full/10.1056/NEJMra1906193 indicate that it has a yearly prevalence of 2%. It has the highest percentage 16 Kessler, R. C., Chiu, W.
