Bipolar Disorder: More Than Just Mood Swings

Mood changes are a normal part of life. However, bipolar disorder is more than ordinary mood swings. It is a mental health condition involving distinct episodes of mania or hypomania and depression. These episodes can affect mood, energy, sleep, thinking, behaviour, relationships, and everyday functioning.

Understanding the signs and symptoms of bipolar disorder, getting an accurate diagnosis and receiving appropriate treatment can help people manage the condition and maintain a better quality of life.

Medical Information: This article provides general health information and is not a substitute for diagnosis or treatment from a qualified mental health professional.

What Is Bipolar Disorder?

Bipolar disorder is a mental health condition characterised by episodes of mania or hypomania and depression. These episodes can cause significant changes in mood, energy, activity, sleep, and behaviour.

Unlike ordinary emotional changes, bipolar episodes can persist for days or longer and may significantly affect daily functioning. Some people also experience periods of stable mood between episodes.

Bipolar disorder should not be diagnosed based on mood changes alone. A qualified mental health professional can assess symptoms, medical history and patterns of behaviour to determine an appropriate diagnosis.

What Are the Symptoms of Bipolar Disorder?

Bipolar disorder symptoms vary depending on whether a person is experiencing mania, hypomania or bipolar depression.

Mania: A Significant Change in Mood and Energy

Mania involves an unusually elevated, expansive or irritable mood along with increased energy or activity.

A person experiencing mania may:

• Need very little sleep without feeling tired
• Talk more rapidly or more than usual
• Experience racing thoughts
• Become easily distracted
• Feel unusually confident or energetic
• Make impulsive or risky decisions
• Spend excessively
• Become unusually restless or goal-directed
• Have difficulty making sound decisions
• Experience hallucinations or delusions in severe cases

Mania can seriously interfere with relationships, work and everyday functioning and may sometimes require hospitalisation.

Hypomania: A Less Severe Elevated State

Hypomania involves elevated or irritable mood and increased energy or activity but is less severe than mania.

A person may feel unusually productive, creative or confident and may sleep considerably less than usual. Because these changes can initially feel positive, hypomania may not always be recognised as a symptom requiring professional assessment.

Bipolar Depression

Bipolar depression involves depressive symptoms that can affect mood, energy, thinking and everyday activities.

Symptoms may include:

• Persistent sadness or low mood
• Loss of interest or pleasure
• Fatigue or low energy
• Changes in sleep or appetite
• Difficulty concentrating
• Feelings of guilt or worthlessness
• Restlessness or slowed movement
• Thoughts of death or suicide

If someone experiences suicidal thoughts or an immediate risk of harm, urgent professional help is important.

Bipolar Disorder vs. Normal Mood Swings

Bipolar disorder is not the same as everyday mood swings.

Normal emotions may change in response to situations, stress or life events and often settle relatively quickly. Bipolar episodes involve more significant and sustained changes in mood, energy, sleep, activity and behaviour.

For this reason, calling someone “bipolar” simply because they are emotional, change their mind or have a bad day can contribute to misunderstanding and stigma.

What Are the Different Types of Bipolar Disorder?

The main types include:

Bipolar I Disorder

Bipolar I disorder involves at least one manic episode. Depressive episodes are common but are not required for the diagnosis.

Bipolar II Disorder

Bipolar II disorder involves hypomanic episodes and major depressive episodes without a history of a full manic episode.

Cyclothymic Disorder

Cyclothymic disorder involves recurring periods of hypomanic and depressive symptoms that do not meet the full criteria for manic, hypomanic or major depressive episodes.

Only a qualified mental health professional can determine which condition best explains a person’s symptoms.

What Causes Bipolar Disorder?

There is no single known cause of bipolar disorder. Research suggests that several biological, genetic and environmental factors may contribute.

Possible factors include:

• Genetic vulnerability
• Brain and biological factors
• Sleep and circadian rhythm disturbances
• Psychological and environmental stress
• Substance use in some individuals

Having a family member with bipolar disorder can increase vulnerability, but it does not mean that a person will definitely develop the condition.

How Is Bipolar Disorder Diagnosed?

Bipolar disorder is diagnosed through a comprehensive psychiatric assessment rather than one single test.

A psychiatrist may evaluate:

• Current and previous mood symptoms
• Changes in sleep and energy
• Behaviour and activity levels
• Previous manic, hypomanic or depressive episodes
• Family mental health history
• Medication and substance use
• Effects on relationships, work and daily life

Is There a Test for Bipolar Disorder?

There is no single blood test, scan or laboratory test that confirms bipolar disorder. Professional diagnosis relies on a detailed assessment of symptoms, history and functioning. Other medical or mental health conditions that can produce similar symptoms may also need to be considered.

Bipolar Disorder Treatment

Bipolar disorder can be treated and managed with appropriate professional care. Treatment is individualised according to a person’s symptoms, diagnosis, medical history and treatment needs.

Medication

Mood stabilisers and other psychiatric medications may be prescribed to manage symptoms and reduce the risk of future episodes. Medication should only be started, stopped or changed under professional medical guidance.

Psychotherapy

Psychological therapies can help people understand symptoms, recognise warning signs, manage stress, develop coping strategies and maintain healthy routines.

Healthy Routines and Support

Consistent sleep, regular physical activity, stress management, avoiding substance misuse and maintaining supportive relationships can complement professional treatment.

What Are the Early Warning Signs of Bipolar Disorder?

Recognising changes from a person’s usual pattern may encourage earlier professional support.

Possible signs of mania or hypomania include:

• Sleeping much less than usual
• Increased talking
• Racing thoughts
• Increased activity
• Unusual confidence
• Impulsive spending
• Increased risk-taking
• Unusual irritability

Possible signs of depression include:

• Social withdrawal
• Loss of interest in usual activities
• Persistent fatigue
• Changes in sleep or appetite
• Difficulty concentrating
• Reduced ability to manage daily responsibilities

Tracking changes in mood, sleep, energy and behaviour can help individuals and families identify patterns to discuss with a mental health professional.

How Can Families Support Someone With Bipolar Disorder?

Family support can play an important role in ongoing care. Families can:

• Learn about bipolar disorder
• Encourage professional treatment
• Support regular sleep and daily routines
• Watch for significant changes in mood or behaviour
• Communicate calmly and without judgement
• Encourage early professional help
• Support treatment recommendations

Severe symptoms, psychosis, dangerous behaviour or thoughts of self-harm or suicide require urgent professional assessment.

When Should You Seek Professional Help?

Consider speaking with a psychiatrist or qualified mental health professional when significant changes in mood, sleep, energy, behaviour or functioning persist or interfere with everyday life.

Because several mental health and medical conditions can produce similar symptoms, professional assessment is important for accurate diagnosis and appropriate treatment.
