Bipolar disorder | Azimuth Check

Bipolar disorder is a mental health condition characterised by episodes of significant changes in mood, energy and activity. These changes can affect sleep, thinking, judgement, relationships and the ability to manage everyday responsibilities. The experience is not simply having good days and bad days. Mood episodes can involve substantial changes from a person's usual state, sometimes lasting days or weeks and, in some cases, longer.

Bipolar disorder is treatable. Understanding its patterns can help people recognise changes, access appropriate care and develop strategies for maintaining stability.

1. What is bipolar disorder?

Bipolar disorder involves episodes of depression and episodes of elevated or irritable mood associated with increased energy or activity. During depression, a person may experience sadness, loss of interest, fatigue, hopelessness, difficulty concentrating and changes in sleep or appetite.

During elevated mood, the person may feel unusually energetic, confident, productive or sociable. They may sleep very little without initially feeling tired, speak more quickly, experience racing thoughts or pursue several activities simultaneously. Some become irritable or impulsive rather than happy. Increased confidence and energy may feel welcome at first, but pronounced mood elevation can affect judgement and lead to risky decisions.

Bipolar disorder is not a personality trait or a choice. Nor does it mean that a person's emotions are always unstable. Many people experience extended periods of relative stability between episodes.

2. Mania and hypomania: what is the difference?

Mania is more severe. It can involve markedly increased energy, reduced need for sleep, rapid speech, racing thoughts, inflated confidence, distractibility and risky behaviour. It can seriously disrupt work and relationships, require hospital treatment and sometimes involve psychotic symptoms, such as delusions or hallucinations.

Hypomania involves a less severe but noticeable change from the person's usual state. They may feel unusually energetic, confident, talkative or productive. Other people may notice the change even when the individual feels particularly capable. Hypomania does not cause the same degree of functional impairment as mania and, by definition, does not involve psychosis.

Bipolar I disorder involves at least one manic episode. Bipolar II disorder involves episodes of hypomania and major depression, without a history of mania. Bipolar II should not be assumed to be mild: depressive episodes can be severe and significantly affect quality of life.

3. Why does bipolar disorder develop?

Bipolar disorder is understood to arise through a complex interaction of biological vulnerability, psychological experience and environmental influences. Genetic factors may contribute to susceptibility, while sleep disruption, stress, substance use and significant life events may influence the onset or recurrence of episodes.

These influences do not provide a simple explanation for any one person's experience. A stressful event may precede an episode, but this does not mean that stress alone caused it. From a psychological perspective, it can be useful to explore how a person experiences changes in mood, how these changes affect their sense of identity and relationships, and how they understand periods of increased energy or depression. Such exploration complements rather than replaces medical treatment.

4. Assessment: recognising the pattern

Bipolar disorder can be difficult to identify because people often seek help during depression, while periods of hypomania or mania may not initially be recognised as symptoms. Assessment therefore considers the history of mood changes over time rather than focusing only on how a person feels at one appointment.

A GP may ask about previous periods of increased energy or activity, reduced need for sleep, impulsivity, depressive symptoms, family history and effects on daily life. Where bipolar disorder is suspected, a specialist mental health assessment may be required. Physical conditions, medication, alcohol or other substances and alternative explanations may also be considered.

Keeping a record of mood, sleep, energy and significant changes in behaviour can help identify patterns. With the person's agreement, information from someone who knows them well may provide useful context.

5. Treatment and ongoing support

Treatment usually combines appropriate medication, psychological support and a plan for recognising changes in mood. Mood stabilisers and certain antipsychotic medicines may be used, depending on the clinical situation. Lithium is an important long-term option and requires regular blood tests and physical health monitoring. Medication should be reviewed with the treating clinician and should not be stopped or changed without medical advice.

Psychological interventions can help people understand their condition, recognise early warning signs, manage distress and address relationship or everyday difficulties. Psychoeducation, cognitive behavioural approaches and family-focused interventions may form part of care.

Maintaining regular sleep and waking times, monitoring changes in energy and mood, managing stress and avoiding recreational drugs may help reduce some risks. A personalised care plan can identify warning signs, useful coping strategies, people to contact and steps to take if symptoms escalate. The aim is to reduce the severity and impact of episodes and support a sustainable quality of life.

6. Living well with bipolar disorder

A diagnosis can raise questions about identity, relationships, work and the future. Recovery does not require denying these difficulties or treating every experience as a symptom. It involves learning to recognise changes, understanding personal patterns and finding ways to maintain stability while continuing to pursue meaningful relationships and activities.

Bipolar disorder is often a long-term condition, but its course varies. With appropriate treatment, ongoing support and an informed approach to self-management, many people achieve greater stability and lead fulfilling lives.

When to seek urgent help

Suspected mania, severe depression, psychotic symptoms or a significant risk of harm require urgent professional assessment. In England, contact NHS 111 and select the mental health option. If there is immediate danger, call 999 or go to A&E.
