Bipolar disorder is a mental health condition marked by significant shifts in mood, energy and activity — between emotional "highs" (mania or hypomania) and "lows" (depression), usually with periods of stability in between. It's not ordinary moodiness or simply being "up and down"; the episodes are intense, last days to weeks, and affect daily life. There are different forms (Bipolar I, Bipolar II and cyclothymia), and because people often seek help during the low phase, it's frequently mistaken at first for depression. The most important thing to know is that bipolar disorder is very manageable: with proper diagnosis and treatment — typically medication, therapy and support — people living with it lead full, stable and successful lives.
We all have ups and downs, but bipolar disorder is something quite different from everyday changes in mood. It's a recognised mental health condition in which a person experiences distinct episodes of unusually elevated mood and energy, and episodes of depression, often with stable periods between them. These shifts are far more intense and longer-lasting than ordinary mood changes, and they can significantly affect a person's life, work and relationships. Understanding what bipolar disorder actually is — and that it is treatable — is the first step toward getting the right help.
Why "bipolar": the name comes from the two "poles" of mood the condition moves between — the elevated, energised state of mania or hypomania at one end, and depression at the other. It was once called "manic depression." It's more common than many realise: the National Institute of Mental Health estimates that around 2.8% of adults experience bipolar disorder in a given year, and about 4.4% at some point in their lives (NIMH).
The types of bipolar disorder
Bipolar I disorder
Defined by at least one full manic episode — a sustained period of extremely elevated or irritable mood and energy — which may be severe enough to need hospital care. Episodes of depression usually occur as well.
Bipolar II disorder
Defined by a pattern of depressive episodes and hypomanic episodes — a milder form of elevated mood than full mania. The depressive episodes are often the most prominent and distressing part, which is partly why it's easily mistaken for depression.
Cyclothymia
A milder, more chronic pattern of mood swings — numerous periods of hypomanic and depressive symptoms over an extended time — that don't quite meet the threshold for the full episodes above, but still affect wellbeing.
Recognising the episodes
Bipolar disorder is understood through its two kinds of episode. Recognising the pattern — not just a single low or high — is what matters.
Mania / hypomania (the "highs")
- Unusually elevated, expansive or irritable mood
- Increased energy and activity, restlessness
- Reduced need for sleep, yet not feeling tired
- Racing thoughts and rapid speech
- Inflated self-confidence or grand ideas
- Impulsive or risky decisions (spending, etc.)
Depression (the "lows")
- Persistent low mood, sadness or emptiness
- Loss of interest or pleasure in things
- Low energy, fatigue, feeling slowed down
- Changes in sleep and appetite
- Difficulty concentrating or deciding
- Feelings of worthlessness or hopelessness
Why bipolar disorder is often mistaken for depression
This is one of the most important things to understand. People living with bipolar disorder very often seek help during a depressive episode — because that's when they feel unwell — while the elevated phases may feel productive or go unnoticed. As a result, bipolar disorder is frequently diagnosed at first as depression. This matters because the treatment is different: treating it as depression alone can miss the fuller picture. If low moods come in episodes, alternate with periods of unusually high energy, or run in the family, it's worth making sure a professional considers bipolar disorder specifically.
It is manageable — and this is the part that matters most. Bipolar disorder is a serious condition, and yes, it carries real risks, including a heightened risk of suicidal thoughts during severe episodes. But that is precisely why getting the right diagnosis and treatment is so important — because treatment genuinely works. With proper care, the episodes can be managed and stability maintained, and people living with bipolar disorder lead full, meaningful and successful lives. A diagnosis is a turning point toward getting better, not a life sentence.
How bipolar disorder is treated
Bipolar disorder is usually managed with a combination of approaches, tailored to the person:
- Medical treatment. Medication — typically mood stabilisers and others — is often central to managing bipolar disorder, and is prescribed and overseen by a psychiatrist. (Decisions about any medication should always be made with a medical doctor.)
- Psychological support and therapy. Talking therapy helps a person understand their condition, recognise early warning signs of an episode, manage stress and triggers, and cope with the emotional impact — working alongside medical treatment.
- Routine and support. Steady sleep, regular routines, reduced stress, and the understanding of family and friends all play a real part in staying well.
If you recognise these patterns in yourself or someone you love, please reach out — bipolar disorder responds well to treatment, and earlier is better. Because medication is often involved, diagnosis and medical care come through a psychiatrist or doctor; alongside that, a consultation with Dr. Kohli offers psychological support — helping you or your loved one understand the condition, manage its impact, and build stability. If anyone is having thoughts of harming themselves, please treat it as urgent and contact a crisis line in your area or your local emergency services without delay.

Frequently asked questions
Is bipolar disorder the same as mood swings?
No. Everyday mood swings are brief and tied to circumstances. Bipolar disorder involves distinct episodes of mania or hypomania and depression that are far more intense, last days to weeks, and significantly affect daily life, work and relationships. It's a recognised medical condition, not simply being "moody" or "up and down."
Can bipolar disorder be cured?
Bipolar disorder is a long-term condition rather than something that's "cured," but it is very manageable. With the right treatment — typically medication overseen by a psychiatrist, alongside therapy and support — episodes can be controlled and stability maintained, and people live full, successful lives. Many people manage it well for decades.
Why is bipolar disorder often misdiagnosed as depression?
Because people usually seek help during a depressive episode, when they feel unwell — while the elevated (hypomanic) phases can feel productive or go unnoticed and unreported. A clinician seeing only the low phase may diagnose depression. That's why it helps to mention any periods of unusually high energy, reduced need for sleep, or a family history, so bipolar disorder can be properly considered.
What should I do if I think I or a loved one has bipolar disorder?
Seek a professional assessment — bipolar disorder responds well to treatment, and getting help early makes a real difference. Because medication is often part of care, diagnosis comes through a psychiatrist or doctor, and psychological support can help alongside. If there are ever thoughts of self-harm, treat it as urgent and contact local emergency services or a crisis line right away.
If bipolar disorder is part of your life or your family's, you don't have to navigate it alone — and with the right care, stability is genuinely within reach. Dr. Prerna Kohli offers warm, confidential psychological support, in person in Gurugram and online across India and for NRIs worldwide.
