What Are Mood Disorders?

Mood disorders comprise a range of mental illnesses that affect a person's life through constant negative emotions such as sadness, anger and unpredictable mood swings. These disorders affect a person’s daily life, relationships and overall health.

Recognising the signs and symptoms of mood disorders early can help individuals take necessary measures to significantly enhance their quality of life.

Types of Mood Disorders

Mood disorders encompass various conditions affecting emotional stability. While some disorders involve chronic sadness, others cause intense mood fluctuations. Early diagnosis and intervention can help manage symptoms effectively, preventing long-term complications.

Major Depressive Disorder (MDD)

Major Depressive Disorder (MDD) is characterised by persistent sadness, loss of interest in activities, fatigue, and difficulty concentrating. People with MDD may experience feelings of hopelessness, sleep disturbances, and appetite changes. If treatment for the same is not undertaken, it can severely impact daily life, work performance, and overall emotional well-being. This condition is one of the most common types of mood disorders.

Bipolar Disorder (I & II)

Bipolar disorder involves extreme mood swings, shifting between manic (high-energy) and depressive (low-energy) episodes. Bipolar I feature severe manic episodes, while Bipolar II is marked by hypomanic (less intense) episodes and prolonged depression. Mood stabilisers and therapy are commonly used for managing bipolar disorder symptoms and mood disorder treatment.

Dysthymia (Persistent Depressive Disorder)

Dysthymia, also known as Persistent Depressive Disorder (PDD), is a chronic form of depression lasting two years or more. Individuals experience mild but long-lasting depressive symptoms, including low energy, self-doubt, and difficulty finding motivation. Although less severe than MDD, its prolonged nature places it under the classification of mood disorders and can affect daily functioning and emotional stability.

Cyclothymic Disorder

Cyclothymic disorder is a milder form of bipolar disorder, causing frequent mood fluctuations that are less extreme than full-blown mania or major depression. These mood swings can disrupt daily activities and cause emotional instability, making it difficult for individuals to maintain consistent relationships, jobs, or personal commitments.

Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder (SAD) is linked to seasonal changes, typically worsening during winter months due to reduced sunlight exposure. Symptoms include fatigue, social withdrawal, irritability, and difficulty concentrating. This is one of the types of mood disorders that responds well to light therapy, vitamin D supplementation, and psychotherapy.

Premenstrual Dysphoric Disorder (PMDD)

Premenstrual Dysphoric Disorder (PMDD) is a severe form of PMS (Premenstrual Syndrome) that causes intense mood swings, depression, and anxiety before menstruation. Symptoms interfere with daily life, leading to increased emotional distress, irritability, and fatigue. PMDD is part of the broader classification of mood disorders and may require hormonal treatments, antidepressants, and lifestyle changes.

What Causes Mood Disorders?

Mood disorders have a biopsychosocial aetiology. The key causes of mood disorders are listed as follows.

Genetic & Biological Factors

A family history of mood disorders is a predisposition for the onset of the same disorders. An imbalance of neurotransmitters, including serotonin and dopamine, may also play a role in the causes of mood disorders.

Environmental Triggers

Trauma, chronic stress, substance abuse and an unhealthy lifestyle are risk factors for the onset of mood disorders. Triggering events may include major life events such as the loss of a loved one or job insecurity—recognised as potential causes of mood disorders.

Hormonal & Neurological Changes

Hormonal changes during pregnancy and menopause affect mood stability. Some illnesses that affect brain function may be a cause of mood disorder.

Signs and Symptoms of Mood Disorders

The signs and symptoms of mood disorders are numerous and may be divided into emotional, physical and behavioural categories. Early recognition of such symptoms may promote timely intervention and mood disorder treatment of the individual.

Emotional Symptoms

An outburst of emotions is often associated with the major emotional disturbances that cause mood disorders, some of which are:

• Persistent sadness or hopelessness: A feeling of persistent helplessness that interferes with regular activities and interactions.
• Increased irritability and mood swings: Abrupt reactions that lead to angry frustration or hypersensitivity.
• Disinterest in normal activities: Things that were once fun, including activities and hobbies, no longer hold the person's interest.
• Excessive feelings of guilt or worthlessness: Self-blame or guilt for things that have gone wrong seem very appropriate.
• Thoughts of harming oneself or suicidal thoughts: At worst, thoughts of self-harm or suicide may flood some people's minds, which should be treated as an emergency.

Physical Symptoms

Physical presentations seem to be relevant to the signs and symptoms of mood disorder, and include:

• Sleep disturbances: Insomnia or excessive sleeping habits that disrupt the normality of daily routines.

• Changes in appetite and weight: Appetite has increased or decreased, indicating significant weight loss or gain.

• Chronic fatigue with low energy: Lethargy is so profound that any task requiring the effort of an elephant feels exhausting.

• Aches and pains for no apparent reason: This applies to headaches, muscle aches or digestive discomfort that add to the suffering of the mood disorder.

• Decreased libido: Lack of interest in sexual relations occurs in conjunction with emotional pain.

Behavioural Symptoms

Interpersonal and professional roles suffer when mood swings show a change in behaviour:

• Social Withdrawal and Isolation: Avoidance of social interactions, family and friends.

• Increased Substance Use or Reckless Behavioural Changes: Use of alcohol, drugs or other harmful activities as a coping mechanism.

• Difficulties at Work and in Relationships: Inconsistent work performance, difficulties in relationships with significant others and general deterioration in social behaviour.

• Restlessness or Restlessness: Fidgeting, pacing or inability to relax due to anxiety or distress.

• Difficulty Concentrating and Making Decisions: Difficulty concentrating or performing a routine task efficiently.

How Are Mood Disorders Diagnosed?

Diagnosis and assessment are carried out by experienced mental health experts to determine the condition in relation to their mood disorders. Such an assessment enables the person to receive the right mood disorder treatment in a timely manner.

Clinical Diagnosis & Tests

• Psychological Assessment: A comprehensive interview in which the person's emotional state, behavioural patterns and personal history are assessed.

• Medical History Review: Assessment of mood swings associated with medical conditions, such as thyroid disease.

• Self-Assessment Questionnaires: Standardised tests that help measure symptoms and their severity.

DSM-5 & ICD-10 Classification

Mood disorders are classified under internationally recognised diagnostic manuals:

• DSM-5 (Diagnostic and Statistical Manual of Mental Disorders): Mainly used in the United States, mood disorders are classified according to this manual.

• ICD-10 (International Classification of Diseases): A system that is recognised worldwide and by medical professionals around the world.

This system supports the classification of mood disorders, enabling clinicians to distinguish one from the other based on symptom patterns.

Differential Diagnosis

Mood disorders may be confused with other psychiatric and medical disorders. The differential diagnosis can distinguish them from others:

• Anxiety disorders
• Schizophrenia spectrum disorders
• Personality disorders
• Substance-induced mood disorders

Mood Disorder Treatment Options

A combination of medical, therapeutic and lifestyle interventions can help treat mood disorders in many effective ways.

Therapy Options (CBT, DBT, Psychotherapy)

CBT and DBT form core components of evidence-based mood disorder treatment plans, especially when tailored to the individual’s needs.

• Cognitive Behavioural Therapy (CBT): This helps people to recognise and change the negative thought patterns that contribute to mood disorders.

• Dialectical Behavioural Therapy (DBT): This includes techniques for emotion regulation and coping with grief.

• Psychotherapy: By creating a space to talk about one's feelings, the coping strategies used and the psychological characteristics of the mental aspect, an environment conducive to emotional expression is created.

Medications

Medication is then used to bring the moods into balance.

• Antidepressants: Used to treat major depressive disorder and dysthymia.

• Mood Stabilisers: Used as a treatment for bipolar disorder to curb extreme mood highs and lows.

• Antipsychotics: Some are administered in cases where very high or low moods are associated with psychotic symptoms.

Lifestyle & Self-Help Strategies

Build healthy habits into a daily routine and simply live a mood-stable life:

• Regular exercise and balanced diet – Physical activity releases endorphins that improve mood.

• Practising mindfulness and meditation – Reduces stress and improves overall healthy emotions through physical well-being.

• Maintaining a stable routine – Get enough sleep and eat a healthy diet.

New & Emerging Treatments

Innovative alternative methods are being researched for such refractory cases:

• Brain Stimulation Therapy: Includes Electroconvulsive Therapy (ECT) for severe depression.

• Ketamine Therapy: A fast-acting treatment option for major depressive disorder.

• Transcranial Magnetic Stimulation: It is a non-invasive brain stimulation technique which is used to improve mood regulation.

Coping Strategies & Support for Mood Disorders

Living with a mood disorder is not easy, but it is possible to develop good coping strategies that improve the functioning of daily life.

Mindfulness & Relaxation Techniques

Guided meditation, deep breathing exercises and journaling are examples of self-help techniques, alongside conventional mood disorder treatment options, that can help manage mood swings and stress. These techniques promote emotional regulation, reduce anxiety, and support clarity of thought, especially when practised consistently with professional guidance and lifestyle improvements.

Support Networks

Family, therapists and peers are sources of emotional support and practical help. Involvement in support groups, regular communication with trusted individuals, and shared experiences can make recovery more manageable and less isolating over time.

Professional Resources

Seeking help from mental health professionals, using therapy apps, and considering rehabilitation centers for intensive care can offer structured recovery paths. Access to timely care, guided programs, crisis intervention, and round-the-clock support ensures individuals are not left to manage symptoms alone or unsupported.
