Bipolar Mood Disorder

Bipolar mood disorder is a psychiatric disorder characterised by periodic swings in mood. Its symptoms include periods of mania and periods of depression, and it can have a major impact on quality of life. During a manic episode a person may feel elated and full of energy, which can itself be exhausting; depressive episodes bring intense sadness and hopelessness.

Episodes in bipolar disorder

Mania

Mania shows itself through increased energy, irritability, overactivity, increased spending, more goal-directed activity (for example excessive sexual activity or spending), a feeling of racing, rapid speech, reduced sleep and, in some cases, hallucinations or delusions. These symptoms must be present for most of the day for at least one week. Functioning is seriously impaired, and hospital admission is often needed.

Depression

Symptoms include loss of pleasure in life (anhedonia), irritability, loss of appetite, lack of motivation, low self-confidence, sleep problems, thoughts of suicide, and difficulty managing small tasks or making simple decisions.

Although the causes are not fully understood, bipolar disorder tends to run in families, and illness or stressful situations can trigger an episode. The lifetime risk of suicide in people with bipolar disorder is around 10–15%, which is why diagnosis and treatment matter so much. Environmental factors, especially stress, are also very important.

Bipolar disorder cannot be diagnosed with laboratory or imaging tests. The diagnosis must be made by a psychiatrist, based mainly on the symptoms, the severity, type, frequency and duration of episodes, and the patient’s personal and family history. The wide variety of presentations often makes the condition hard to recognise and diagnose.

Living with bipolar disorder

Bipolar disorder can affect people of any age, though it most often begins in adolescence or early adulthood. Gender, culture, social status and income have not been shown to change the likelihood of developing it. Self-care is especially important: regular sleep, healthy eating, exercise, stress management and taking medication as prescribed all help keep mood stable. Early treatment and a suitable treatment plan help to minimise the impact of the illness on quality of life.

People with bipolar disorder need a supportive family environment and a reliable healthcare provider. The illness also affects family members and social relationships; patients may find it hard to communicate with friends and family, feel excluded or withdraw from social activities. Families can help by learning to recognise symptoms and early warning signs and by supporting adherence to therapy and medication. Common myths, for example that patients will not respond to treatment, can never get better, cannot control themselves or can “pass on” the illness to others, are wrong. With an appropriate treatment plan, bipolar disorder can be managed well.

Bipolar mood disorder: clinical pictures, aetiology and modern treatment approaches

Author: Prof. Dr. Ali Keyvan, Psychiatrist

Abstract

Bipolar mood disorder is a chronic, recurrent brain disorder characterised by extreme, cyclical fluctuations in a person’s mood, thinking, energy and functioning. Formerly known as “manic-depressive illness”, it can be understood through the metaphor of a pendulum swinging between periods of mania or hypomania, when exuberance and elation peak, and periods of depression, when a deep collapse is experienced. This article aims to give a comprehensive account of the clinical spectrum of bipolar disorder (bipolar I, bipolar II and cyclothymia), current knowledge of its aetiology, and evidence-based modern treatment strategies. It examines the strong genetic and neurobiological vulnerability underlying the disorder and the triggering role of environmental stressors and disrupted circadian rhythms. The treatment section highlights the central role of mood stabilisers, above all lithium, the effectiveness of atypical antipsychotics and the critical points to watch with antidepressants. Alongside psychopharmacology, it discusses the essential place of psychoeducation and psychotherapies such as interpersonal and social rhythm therapy (IPSRT) and cognitive behavioural therapy (CBT) in managing the illness, preventing relapses and improving quality of life.

1. Introduction

In clinical practice, patients we diagnose with bipolar disorder, and their families, often face confusion, fear and worry about stigma. Yet this disorder is not a weakness of will or a flaw of character; like diabetes or hypertension, it is a chronic medical condition with biological foundations that needs to be managed. Its core feature is mood oscillating between two opposite poles. These swings can dramatically affect a person’s relationships, career and, most fundamentally, their life. Because of consequences such as a high risk of suicide, co-occurring substance use disorders and serious loss of functioning, accurate diagnosis and effective treatment are vital.

2. The clinical spectrum: the different faces of the disorder

Bipolar disorder does not fit a single pattern; it appears as a spectrum.

• Manic episode: the “exuberant” pole of the disorder. It is characterised by an abnormally and persistently elevated, expansive or irritable mood lasting at least one week. Symptoms include:

  • reduced need for sleep (for example, feeling rested after 2–3 hours a night)

  • inflated self-esteem or grandiosity

  • being much more talkative than usual, pressured speech (fast, continuous speech that is hard to interrupt)

  • flight of ideas or the feeling that thoughts are racing

  • distractibility

  • increased goal-directed activity (social, work or sexual) or psychomotor agitation

  • excessive involvement in pleasurable activities with a high potential for painful consequences (for example, overspending, reckless business investments, inappropriate sexual behaviour). A manic episode usually seriously impairs functioning and may require hospital admission.

• Hypomanic episode: a milder form of mania. The symptoms are the same but less severe; they last at least four days and do not impair functioning enough to require hospital admission. A person in a hypomanic episode may look energetic, creative and productive from the outside, but this state is usually not sustainable and often heralds a collapse.

• Major depressive episode: the “collapse” pole of the disorder, whose symptoms may be indistinguishable from unipolar depression: low mood, loss of pleasure (anhedonia), changes in weight or appetite, sleep problems (insomnia or oversleeping), feelings of worthlessness and guilt, low energy and thoughts of suicide.

Depending on the pattern of these episodes, bipolar disorder is divided into subtypes:

• Bipolar I disorder: at least one manic episode is enough for the diagnosis. Depressive episodes are common but not required.

• Bipolar II disorder: characterised by a history of at least one hypomanic episode and at least one major depressive episode. These patients have never had a full manic episode, and they are often misdiagnosed with depression alone.

• Cyclothymic disorder: a chronic picture lasting at least two years, with recurring hypomanic and depressive symptoms that do not meet the full criteria for a hypomanic or depressive episode.

3. Aetiology: a current view of the causes

• Genetic vulnerability: the strongest factor in the aetiology of bipolar disorder. A person with a first-degree relative with bipolar disorder has roughly ten times the risk of the general population, showing that the illness has a strong hereditary and biological basis.

• Neurobiological findings: brain imaging and neurochemical studies point to problems in communication between the brain regions responsible for regulating mood, such as the prefrontal cortex, amygdala and hippocampus. Imbalances in neurotransmitter systems such as serotonin, noradrenaline and especially dopamine are thought to underlie manic and depressive episodes.

• Psychosocial triggers: in a genetically vulnerable person, environmental factors such as major life events (bereavement, work stress, trauma) or disruption of the sleep–wake cycle can trigger the first episode or worsen the course of the illness.

4. The cornerstones of treatment: a holistic approach

Treating bipolar disorder is less a “cure” than a lifelong process of “management”, and it rests on two main pillars.

A. Psychopharmacology (medication): the backbone of treatment.

• Mood stabilisers: the primary medicines, used both to treat acute episodes and to prevent new ones. Lithium is considered the “gold standard” of bipolar treatment and has proven effectiveness, particularly in reducing suicide risk. Other antiepileptic medicines such as valproic acid, lamotrigine and carbamazepine are also widely used.

• Atypical antipsychotics: medicines such as olanzapine, quetiapine and risperidone are highly effective, especially in controlling acute mania and mixed episodes and in long-term maintenance treatment.

• Antidepressants: the most delicate issue in bipolar treatment. Prescribing an antidepressant on its own to a patient with bipolar depression can trigger a switch into mania or hypomania. Antidepressants must therefore always be used with great care and together with a mood stabiliser or an atypical antipsychotic.

B. Psychotherapy: an indispensable component that increases the effectiveness of medication and improves quality of life.

• Psychoeducation: informing both patient and family about the nature of the illness, its symptoms, early warning signs, triggers and the importance of treatment is the foundation of the whole treatment process.

• Interpersonal and social rhythm therapy (IPSRT): developed specifically for bipolar disorder, it aims to stabilise circadian rhythms by regulating daily routines (sleep and waking, meals, social activities) and to help patients cope with interpersonal stressors.

• Cognitive behavioural therapy (CBT): helps patients recognise and manage negative thinking patterns during depressive periods and overconfident, risky thinking during manic periods.

• Family-focused therapy: strengthens communication within the family, reduces conflict and helps the family offer a more supportive environment.

5. Conclusion: a lifelong companion

Bipolar disorder can be managed successfully with the right treatment plan and a strong therapeutic alliance. The aim of treatment is to prevent episodes and to enable the person to lead a productive, fulfilling life in harmony with this “companion”. Early diagnosis, effective medication, regular psychotherapy and healthy lifestyle habits are the keys to achieving this. For more detailed information, please contact our doctor.
