Moods and Mood Disorders

  • Definition of Mood

    • Mood refers to one’s overall emotional state and well-being at any given moment.

    • It's a complex interaction of thought, emotion, sensation, and perception.

    • Mood is linked to consciousness and influenced by various factors:

    • Internal thoughts

    • Sensations

    • Perceptions

    • Temperament

  • Factors Influencing Mood

    • Moods are influenced by both psychosocial factors (positive and negative experiences) and physiological/neurological aspects.

    • Genetic components can play a role, but circumstances are significant drivers of mood changes.

    • Everyone has a spectrum of normal mood states; fluctuations in mood are typical.

    • Examples of variability in mood expression:

    • Some people may feel emotions intensely, while others are more stoic.

  • Normal Mood Fluctuations

    • Mood changes can typically be traced back to:

    • Activity levels

    • Sleep patterns

    • Food or water intake

    • Interpersonal issues

    • It is normal to experience drastic changes in mood, including tiredness and excitement.

  • Mood Disorders

    • Diagnosed when mood changes are severe or unpredictable.

    • Mood disorders often involve extreme sadness or artificial elation.

    • Prevalence: Approximately 10-20% of adults are affected, with a higher incidence in women.

    • Mood disorders often co-occur with anxiety, substance use, and personality disorders.

    • Trauma exposure and genetic predisposition are significant indicators.

    • Evidence of neurochemical implications exists but has limitations (e.g., chemical imbalance theory).

Components of a Mood Disorder Diagnosis

  • Distinctions in Mood Experience

    • It’s crucial to differentiate between normative mood variations and mood disorders.

    • Common misdiagnosis by patients claiming "I am depressed" or "I have bipolar disorder" due to normative ups and downs.

  • Classification of Mood Disorders

    • Two main categories:

    1. Depressive Disorders

    2. Bi-Polar Related Disorders

  • Mood Episode Definition

    • A mood episode is characterized as a discrete period where mood is notably altered.

    • Distinction between episodes (normal reactions) vs. mood disorders (persistent symptoms).

Types of Mood Episodes

  • Depressive Episodes: Includes major depression and depressive disorders. Characterized by symptoms such as:

    • Low mood

    • Sadness

    • Apathy

    • Withdrawal

    • Loneliness

  • Manic Episodes: Linked with Bi-Polar I Disorder where symptoms include:

    • Elevated mood or irritability

    • Increased energy

    • Involvement of impulsive behaviors or psychosis.

  • Hypomanic Episodes: A milder version of mania characterized by:

    • Duration of 4 + days

    • Noticeable shifts in mood without high impairment.

Major Depressive Episode

  • Core Characteristics:

    • Prolonged low/negative mood states for over 2 weeks, impacting daily functioning.

  • Symptoms of Major Depression:

    1. Depressed mood

    2. Loss of interest in activities

    3. At least four of the following:

    • Fatigue

    • Inability to concentrate

    • Feelings of worthlessness or guilt

    • Thoughts of suicide

  • Duration: Persistent for more than two weeks.

  • Severity: Must cause significant distress or impairment; not due to other medical or substance-related conditions.

  • Considerations in Diagnosis:

    • Patients may vary in recognizing depression; symptoms can differ dramatically.

    • An essential requirement is a noticeable change from the patient's usual functioning.

The Depressive Disorders

  • Major Depressive Disorder (MDD):

    • Defined as having at least one major depressive episode with no history of manic/hypomanic episodes (prevalence: ~7% of the population).

    • Importance of correct diagnosis to avoid inappropriate treatment (antidepressants).

    • High risk for suicidal ideation and behaviors; necessitates rigorous risk assessments.

  • Specifiers for MDD:

    1. Single vs. Recurrent Episodes

    2. Seasonal Patterns

    3. Severity/Remission Status

    4. Rapid Cycling Episodes (more than 4 in a year)

    5. Atypical Features

    6. Psychotic Features

    7. Catatonic Features

    8. Co-Morbidity with other conditions

    9. Peripartum Onset

    10. Melancholic Features

  • Persistent Depressive Disorder (PDD):

    • Chronic low-grade depression lasting at least 2 years (1+ year for children).

    • Symptoms include persistent low mood, fatigue, and chronic negative thought patterns (Beck's Depressive Triad).

Other Considerations Regarding Depression Symptoms

  • The impact of substances and medical conditions on mood.

  • Contextual factors (stressors) affecting mood should not be overlooked.

  • Differential diagnoses could include:

    • Premenstrual Dysphoric Disorder (PMDD)

    • Adjustment Disorder with mood symptoms

  • The complex nature of lived experiences including:

    • Biological/Physiological factors

    • Psychological/Emotional influences

    • Social/Interpersonal dynamics

    • Ecological/Spiritual contexts.

The Manic Episode

  • Definition: Mania as the opposite of depression, marked by an elevated but sometimes negative mood.

  • Symptoms of Mania:

    • Elevated mood or irritability

    • Increased energy, at least three additional symptoms:

    • Grandiosity

    • Talkativeness

    • Poor judgment

  • Duration: More than one week, or any duration requiring hospitalization.

  • Severity: Often leads to significant impairment.

  • Distinction from other conditions (not due to medical conditions or substances).

  • Risks during Manic Episodes:

    • High propensity for taking risks and engaging in impulsive behaviors leading to legal/social consequences.

  • Importance of identifying and managing manic episodes for treatment plans.

The Hypomanic Episode

  • Definition: A milder version of mania, characterized as “mania lite”.

  • Symptoms are similar to mania but less severe.

  • Duration: More than four days.

  • Severity: Noticeably changes mood without causing significant impairment.

  • Difficulty in diagnosis may arise due to the baseline mood of the individual, especially if they have dysthymia.

Bipolar and Related Disorders

  • Definition: Bipolar disorders characterized by alternating high (mania) and low (depression) moods.

  • Types of Bipolar Disorders:

    1. Bipolar I Disorder: At least one manic episode, can include depressive episodes.

    2. Bipolar II Disorder: At least one hypomanic and one depressive episode, but no manic episode.

    3. Cyclothymic Disorder: Chronic mood swings over 2 years that do not meet criteria for other classifications.

    4. Disruptive Mood Dysregulation Disorder: Severe tantrums occurring three times a week, persistent irritability, and angry moods before age 18.

  • Challenges in differential diagnosis, including:

    • ADHD

    • Autism

    • Childhood Bipolar Disorder

  • Specifiers:

    • Rapid Cycling

    • Seasonal Patterns

    • Severity mentions (Mild to Severe)

    • Co-Morbidity with anxiety or psychotic features.

Vital Considerations for Bipolar and All Mood Disorders

  • Important to rule out other caused mood disturbances, including:

    • Substance-induced effects

    • Medical conditions and physiological explanations

    • Environmental/contextual factors

    • Cultural and socio-economic environments

  • Importance of suicide risk monitoring and interventions with both depressive and bipolar disorders.

Concepts of Suicide and Risk Assessment

  • Suicide: Defined as taking lethal actions against oneself; significantly associated with depression and certain personality disorders.

    • Global statistics indicate 788,000 deaths yearly, with depression significantly heightening the risk.

  • Suicidal Ideation (SI): Thoughts or fantasies about suicide which can vary in intensity.

    • Not all SI indicates a desire to die; situational context matters.

  • Suicide Risk Assessment:

    • Consider the following:

    • Thoughts: Evaluate persistence and specific content.

    • Plan: Understand if the individual has a specific method.

    • Intention: Determine if they intend to act on the plan.

    • Means: Assess if they have the means to carry out their plan.

    • Protective Factors: Identifying resources like social support or coping strategies.

    • In case of imminent risk, refer to emergency services for intervention.

Other Causes of Mood Symptoms and Treatments of Mood Disorders

  • Contextual Mood Variability: Some individuals show varying sensitivity to stress based on environmental conditions at micro, mezzo, and macro levels.

  • Adjustment Disorder: Commonly used diagnosis for varied depressive symptoms due to life situations.

  • Other Disorders Influencing Mood:

    • Personality Disorders (emotional regulation issues)

    • Schizoaffective Disorder (psychosis with mood symptoms)

    • Prolonged Grief (complicating the differentiation between mourning and depression)

    • Neurocognitive Disorders affecting mood through cognitive decline.

Treatment of Mood Disorders

  • Treatment Strategies:

    • Psychotherapy combined with lifestyle changes and daily living adjustments.

    • Cognitive Behavioral Therapy (CBT) is particularly effective.

    • Mindfulness-based approaches and humanistic, person-centered strategies are well-documented.

    • Holistic approaches are advocated due to complex drivers behind depression today, encompassing biological, psychological, and environmental factors.

  • Medications:

    • Use of antidepressants, differing in mechanisms, typically aiming to increase serotonin and/or norepinephrine levels.

    • There is an ongoing debate regarding the validity of the serotonin theory of depression as a possible myth.
