Mood Disorders

Mood disorders, also known as affective disorders, are complex, multifaceted conditions that affect an individual’s emotional well-being, disrupting daily routines, work productivity, and personal relationships. These disorders go beyond temporary mood fluctuations, influencing how a person thinks, feels, and interacts with the world. Whether it is Major Depressive Disorder (MDD), Bipolar Disorder, Persistent Depressive Disorder (Dysthymia), or other mood-related conditions, those affected often struggle with motivation, emotional stability, and social engagement, leading to a cycle of distress that can be challenging to break without intervention.   

The impact of mood disorders extends beyond mental and emotional distress, significantly affecting physical health over time. Studies have linked prolonged depression and bipolar disorder to chronic conditions such as heart disease, diabetes, and a weakened immune system, increasing vulnerability to other health complications. Mood disorders can also disrupt sleep patterns, appetite, and energy levels, leading to persistent fatigue and a reduced quality of life. In severe cases, the overwhelming sense of hopelessness associated with mood disorders may result in self-harm or suicidal ideation. This makes early intervention, proper treatment, and a strong support system essential in helping individuals manage their condition effectively and regain control over their lives.

Causes of Mood Disorder 

The exact cause of mood disorder is not fully understood, but researchers believe they result from a complex interaction of biological, psychological, and environmental factors. 

Biological Causes 

• Genetics: A family history of depression or bipolar disorder can increase the risk of developing a mood disorder.   

• Brain Chemistry Imbalance: Low or fluctuating levels of neurotransmitters like serotonin, dopamine, and norepinephrine are associated with mood instability.   

• Hormonal Changes: Imbalances in cortisol (stress hormone), estrogen, and thyroid hormones can trigger mood disturbances.  

• Chronic Illnesses: Conditions like diabetes, heart disease, and autoimmune disorders have been linked to an increased risk of depression and mood instability.   

 Psychological Causes 

• Negative Thought Patterns: Individuals with low self-esteem, chronic pessimism, and excessive worry are more prone to mood disorders. 

• Unresolved Trauma: Childhood abuse, neglect, the loss of a loved one, or severe emotional distress can contribute to depressive episodes and mood fluctuations. 

 Environmental and Lifestyle Factors 

• Chronic Stress: Prolonged exposure to workplace stress, financial difficulties, or relationship conflicts can lead to emotional dysregulation and depression.    

• Social Isolation: A lack of emotional support and loneliness can worsen depressive symptoms of depression and bipolar disorder. 

• Substance Abuse: Alcohol and drug use can disrupt brain chemistry, increasing the severity of mood disorders and interfering with treatment. 

Classification and Types of Mood Disorders 

 Mood disorders are categorized into three primary types: depressive disorders, bipolar disorders, and related disorders. 

Depressive Disorders 

These disorders are characterized by persistent low mood, sadness, and a loss of interest in activities. The most common depressive disorders include:  

• Major Depressive Disorder (MDD): Severe depression lasting at least two weeks, affecting daily life. 
• Persistent Depressive Disorder (Dysthymia): Chronic depression lasting two years or more, with less severe but ongoing symptoms. 
• Seasonal Affective Disorder (SAD): Depression that occurs during specific seasons, usually winter, due to reduced sunlight exposure. 
• Postpartum Depression: Severe depression occurring after childbirth. 

Bipolar Disorders 

Bipolar disorders involve mood swings between extreme highs (mania or hypomania) and extreme lows (depression). Types include: 

• Bipolar I Disorder: Characterized by full manic episodes that may require hospitalization. 
• Bipolar II Disorder: Involves hypomanic episodes (less severe than mania) along with major depressive episodes. 
• Cyclothymic Disorder: Chronic mood swings that are less extreme but last for at least two years. 

Related Mood Disorders 

• Disruptive Mood Dysregulation Disorder (DMDD): A childhood condition involving severe irritability and frequent outbursts. 
• Premenstrual Dysphoric Disorder (PMDD): Severe mood disturbances linked to the menstrual cycle. 

Symptoms of Mood Disorder 

Symptoms of mood disorder vary from person to person but generally include a combination of emotional, physical, and cognitive symptoms that persist for at least two weeks. 

Emotional Symptoms 

• Persistent sadness or hopelessness 
• Loss of interest in activities once enjoyed 
• Feelings of guilt or worthlessness 
• Increased irritability or mood swings 
• Suicidal thoughts or self-harm tendencies 

Physical Symptoms 

• Fatigue or low energy 
• Sleep disturbances (insomnia or excessive sleeping) 
• Changes in appetite (weight loss or gain) 
• Unexplained body aches, headaches, or digestive issues 

Cognitive Symptoms 

• Difficulty concentrating or making decisions 
• Memory problems 
• Slowed thinking or difficulty processing information 

Symptoms Primarily Seen in Bipolar Disorder 

• Elevated or irritable mood 
• Increased energy and reduced need for sleep 
• Racing thoughts, rapid speech, and impulsivity 
• Grandiose thinking (inflated sense of self-importance) 
• Engaging in risky behaviours (spending sprees, reckless driving) 

Diagnosis of Mood Disorder  

 A precise diagnosis of mood disorders is essential for developing an effective rehabilitation and therapy plan tailored to an individual’s needs. Since mood disorders affect emotions, cognition, behaviour, and physical health, a thorough evaluation ensures that treatment is personalized, evidence-based, and goal-oriented.  

Diagnosing mood disorders requires a comprehensive assessment conducted by mental health professionals, including psychiatrists, psychologists, and therapists. These professionals collaborate to determine the severity of symptoms, potential triggers, and the best course of treatment. 

Clinical Evaluation and Diagnostic Criteria 

The first step in diagnosing mood disorders is conducting a clinical interview based on standardized psychiatric guidelines. The most commonly used diagnostic approaches include: 

• Defining mood disorder based on the presence, duration, and intensity of symptoms.   
• Classifying depression or bipolar disorder severity and its impact on an individual’s quality of life.  
• Screening for comorbid conditions such as anxiety disorders, PTSD, or personality disorders.
   

Psychological and Cognitive Assessments 

Once clinical symptoms are identified, structured psychological assessments are conducted to evaluate:  

• Severity of depression or mania: Categorized as Mild, Moderate, or Severe. 
• Cognitive functioning: Assessing memory, attention, and executive function (especially in elderly patients or those with suspected neurological conditions). 
• Suicidal risk evaluation: Screening for self-harm tendencies or suicidal ideation. 

These assessments help customize rehabilitation programs by identifying the most urgent areas of intervention, whether it be emotional support, cognitive restructuring, medication management or crisis management. 

Medical and Physical Health Evaluation 

Because mood disorder often coexists with physical health conditions, a medical evaluation is necessary to rule out underlying medical causes that may contribute to depression-like or mood instability symptoms, such as: 

• Thyroid disorders (hypothyroidism or hyperthyroidism): Can cause depressive or manic symptoms. 
• Chronic illnesses (diabetes, cardiovascular disease, chronic pain): May contribute to or worsen mood disorder. 
• Neurological conditions (stroke, dementia, Parkinson’s disease): Depression is common in neurodegenerative disorders. 
• Vitamin deficiencies (Vitamin D, B12, folate): Can influence mood regulation.  
• Hormonal imbalances (cortisol, estrogen, testosterone): May trigger mood instability. 

Laboratory Tests for Mood Disorder Diagnosis 

To rule out biological causes, the following tests may be recommended: 

• Thyroid function tests to check for hypothyroidism or hyperthyroidism. 
• Complete blood count (CBC) to detect anemia or infections that may impact mood. 
• Metabolic panels assess blood sugar, liver, and kidney function. 
• Vitamin level tests checking Vitamin D, B12, and folate levels. 

Treatment for Mood Disorder 

While antidepressant medications can be effective, many individuals prefer non-medication treatments that focus on natural and therapeutic approaches to recovery. Among these, psychotherapy is one of the most effective, evidence-based interventions for managing mood disorders.   

Psychotherapy (Talk Therapy) for Mood Disorder 

Psychotherapy, also known as talk therapy, involves structured conversations with a trained mental health professional to help individuals recognize negative thought patterns, regulate emotions, and develop healthier coping mechanisms. Therapy provides a safe and supportive space to address emotional challenges, improve self-awareness, and build practical strategies for managing depression and mood instability. 

There are multiple types of psychotherapy available for mood disorder, each with unique benefits. Choosing the right therapy depends on personal needs, symptom severity, and treatment goals. 

Below are some the most widely used methods: 

• Cognitive-Behavioural Therapy (CBT): 
  Cognitive-Behavioural Therapy (CBT) is one of the most widely used and evidence-based psychotherapies for mood disorders. It is based on the idea that thoughts, emotions, and behaviours are interconnected, meaning that negative thinking patterns can contribute to emotional distress and self-destructive behaviours.  

• • Key benefit of CBT: 
    • Identifies negative thought patterns 
    • Reframes negative thinking 
    • Develops coping strategies 
    • Encourages behavioural activation 
    • Reduces self-destructive behaviours
       
• Interpersonal Therapy (IPT): 
  Interpersonal Therapy (IPT) is a structured therapy that focuses on improving relationships and social interactions.  It helps individuals develop healthier, more supportive relationships while addressing underlying emotional struggles linked to interpersonal challenges. 
  • Key benefit of IPT: 
    • Addresses social and relationship issues 
    • Targets four key areas of emotional distress: 
    • Grief and loss processing 
    • Adjusting to major life changes  
    • Resolving interpersonal conflict 
    • Encouraging social engagement 
    • Improves emotional expression 

• Psychodynamic Therapy
  Psychodynamic Therapy is a long-term, insight-oriented approach that focuses on uncovering unconscious conflicts, past experiences, and unresolved emotions that contribute to mood instability. It is based on the belief that deep-seated emotional struggles, often rooted in childhood experiences, can influence present-day behaviours and feelings. 

  Psychodynamic Therapy is particularly useful for individuals with long-term, recurring depression or those who feel that their emotional struggles are deeply rooted in past experiences. 

• • Key benefit of Psychodynamic Therapy: 
    • Explores unconscious patterns 
    • Encourages self-reflection 
    • Helps release repressed emotions 
    • Strengthens emotional resilience 

• Dialectical Behaviour Therapy (DBT)
  Originally developed for Borderline Personality Disorder (BPD), Dialectical B Behaviour Therapy (DBT) is highly effective in treating severe mood swings, self-harm tendencies, and emotional dysregulation. It combines elements of CBT techniques with mindfulness and distress tolerance strategies.
  DBT is particularly beneficial for individuals with intense mood swings, suicidal thoughts, or impulsive behaviours associated with mood disorder. 

• • Key benefit of DBT: 
    • Teaches emotional regulation 
    • Develops distress tolerance skills 
    • Encourages mindfulness practices 
    • Improves interpersonal effectiveness 

• Behavioural Activation Therapy
  Behavioural Activation Therapy is a structured, goal-oriented approach that focuses on re-engaging individuals in meaningful and enjoyable activities to counteract the withdrawal and inactivity caused by depression or mood swings.
  Behavioural Activation is especially useful for individuals who struggle with low energy, lack of motivation, and withdrawal from daily activities. 

• • Key benefits of Behavioural Activation: 
    • Encourages activity planning 
    • Rebuilds social connections 
    • Promotes positive reinforcement 
    • Reduces avoidance behaviours 

• Group Therapy
  Group Therapy provides a supportive, structured environment where individuals can share their experiences, learn from others, and develop social support networks. It is typically led by a trained therapist and can be a stand-alone treatment or combined with individual therapy. 

• • Key benefits of Group Therapy: 
    • Provides a sense of community 
    • Encourages peer support 
    • Enhances social skills 
    • Promotes accountability and motivation 

• Family or Couples Therapy
  Family or Couples Therapy is recommended when interpersonal relationships contribute to mood instability. It focuses on improving communication, resolving conflicts, and fostering a more supportive home environment. 

• • Key benefits of Family or Couples Therapy: 
    • Addresses relationship conflicts 
    • Encourages emotional support  
    • Improves communication skills 
    • Identifies negative family patterns
