Bipolar Symptoms: Recognising the Signs

Bipolar disorder is one of the most misunderstood mental health conditions. It’s often reduced to “mood swings” in everyday conversation, but the reality is far more complex. For someone living with bipolar disorder, the shifts between highs and lows can be profound, disruptive, and at times dangerous. Recognising the symptoms early can make a significant difference in getting the right treatment and preventing future episodes.

What Is Bipolar Disorder?

Bipolar disorder is a mental health condition characterised by significant shifts in mood, energy, and activity levels. These shifts go beyond the normal ups and downs that everyone experiences. A person with bipolar disorder moves between periods of elevated or irritable mood (mania or hypomania) and periods of low mood (depression), often with periods of stability in between.

The pattern and severity of these episodes can vary considerably from person to person, which is why a thorough psychiatric assessment is essential for an accurate diagnosis.

The Highs: Mania and Hypomania

Manic and hypomanic episodes are periods of abnormally elevated mood and energy. Hypomania is a milder form — while the person may feel productive and energetic, mania is more severe and can cause significant impairment. Symptoms during these periods may include:

Reduced need for sleep — feeling rested or energised after only a few hours, or not sleeping at all.
Racing thoughts — ideas flying through the mind faster than they can be expressed.
Increased energy and activity — taking on multiple projects, feeling driven to keep moving.
Heightened confidence or grandiosity — feeling invincible, unusually important, or capable of anything.
Talkativeness — speaking more rapidly or more than usual, sometimes hard for others to follow.
Risk-taking behaviour — making impulsive decisions around spending, relationships, or activities that carry real risk.
Irritability — feeling frustrated or agitated, especially when others don’t share their enthusiasm.

One of the challenges with hypomania is that it can feel good. The person may be productive, sociable, and creative — which is why they may not recognise it as a symptom. However, hypomania can escalate into mania, and even on its own, it can lead to decisions that have lasting consequences.

The Lows: Depressive Episodes

Depressive episodes in bipolar disorder can be devastating. The contrast with a preceding high can make the low feel even more disorienting. Symptoms may include:

Persistent low mood — feeling sad, empty, or hopeless for most of the day, nearly every day.
Loss of interest — no longer enjoying activities that were previously pleasurable.
Fatigue and low energy — even small tasks feel exhausting.
Changes in sleep — sleeping much more than usual or struggling to sleep despite exhaustion.
Changes in appetite — significant weight loss or gain, or loss of interest in eating.
Difficulty concentrating — struggling to focus, make decisions, or remember things.
Feelings of worthlessness or guilt — harsh self-criticism or rumination on past events.
Thoughts of death or suicide — which require immediate attention from a health professional.

If you or someone you know is experiencing thoughts of suicide, it’s important to seek help immediately. Contact Lifeline on 13 11 14, or call 000 in an emergency.

Patterns and Types

Bipolar disorder isn’t a single, uniform condition. The pattern of episodes helps clinicians determine the specific type. In bipolar I disorder, there is at least one full manic episode. In bipolar II disorder, there are hypomanic and depressive episodes, but never a full manic episode. There are also other patterns, including cyclothymia, which involves chronic, less severe fluctuations.

Understanding the pattern matters because it guides treatment. A psychiatrist will look at the frequency, duration, and severity of episodes, any triggers, and the presence of other conditions to make an accurate diagnosis and develop an appropriate treatment plan.

When Symptoms Overlap

Bipolar disorder can be tricky to identify because its symptoms overlap with other conditions. A depressive episode can look like major depressive disorder. A hypomanic episode can look like someone simply doing well. Irritability during mania can be mistaken for anger issues. And some symptoms — like racing thoughts and restlessness — can resemble anxiety or ADHD.

This is why it’s so important to give a treating clinician a full picture of your experiences over time, not just how you feel on a particular day. A history of even one period of elevated mood — especially with reduced need for sleep — can be the key to distinguishing bipolar disorder from unipolar depression.

When to Seek Help

If you recognise these patterns in yourself — particularly if you’ve experienced periods of elevated mood with reduced need for sleep, followed by significant lows — it’s worth speaking with a health professional. Your GP is a good starting point and can discuss whether a referral to a psychiatrist would be appropriate.

You might also consider taking our free bipolar self-assessment (MDQ) to reflect on what you’ve been experiencing. It’s confidential and takes only a few minutes. While it isn’t a diagnosis, it can be a useful starting point for a conversation with your GP or psychiatrist.

For a comprehensive assessment, a psychiatrist experienced in bipolar disorder can explore your full history, confirm the diagnosis, and work with you on a treatment plan tailored to your specific pattern of episodes.

Treatment and Support

Bipolar disorder is a treatable condition. With the right combination of support, many people lead full, productive lives. Treatment typically involves mood-stabilising strategies, which may include medication and psychological therapy, as well as lifestyle approaches like maintaining regular sleep patterns and managing stress. The goal is not just to treat the current episode but to reduce the frequency and severity of future ones.

Early recognition and treatment can make a significant difference. If you’re ready to explore support, talk to your GP about a referral, then get in touch to arrange a telehealth consultation.
