Study Notes

Mood Disorders Overview

  • Mood disorders primarily encompass depressive disorders and bipolar disorder, characterized by abnormal moods: depression and elation.
  • Historically, the term "affective disorders" has been used interchangeably with mood disorders.

Depressive Disorders

  • Depressed mood is a common experience during adversity but separates clinical conditions from transient unhappiness or symptomatology of other disorders.
  • Core features are:
    • Depressed mood
    • Negative thinking
    • Anhedonia (lack of enjoyment)
    • Reduced energy
    • Psychomotor slowness

Clinical Features of Depression

  • Severity of depressive states varies; classifications include episodes of severe depression and their clinical variants.
  • Diagnosis of ‘depressive episode’ relies on symptomatology defined in ICD-10 & DSM-5:
    • DSM-5 requires five or more symptoms that cause significant distress or functional impairment.

Severe Depressive Episode

  • Major characteristics are low mood, anhedonia, negativity, and reduced energy impacting social and occupational functioning.

Feelings of Guilt

  • Patients may experience intense self-blame linked to trivial past events, increasing in frequency with deepening depression.
  • Guilt can be unfocused or tied to specific unhappy memories, often attributing personal failures as a reason for misery.

Goal-directed Behavior

  • Anhedonia is a key symptom indicating moderate to severe depression; leads to social withdrawal, energy depletion, and unfinished tasks.

Psychomotor Changes

  • Psychomotor Retardation: Diminished movement, slow speech, leading to delays in interaction.
  • Agitation: Active restlessness often interpreted as motivated, when it may reflect inner turmoil.

Anxiety in Depression

  • Anxiety is frequently observed, often encompassing irritability, particularly in adolescents.

Biological Symptoms

  • Grouped as "vegetative" symptoms, they include:
    • Sleep disturbances (early morning waking)
    • Mood diurnal variation
    • Appetite and weight fluctuations
    • Loss of libido

Psychotic Depression

  • In severe cases, depressive disorders can result in profound functional impairment, neglecting personal hygiene, and potentially presenting delusions and hallucinations.

Clinical Variants of Depressive Disorders

  • Agitated Depression: Characterized by heightened restlessness; often seen in older patients.
  • Retarded Depression: Noted for psychomotor retardation; can indicate good electroconvulsive therapy response.
  • Depressive Stupor: Severe slowing of movement and communication; rare due to modern treatments.

Delusions in Depression

  • Common themes include feelings of worthlessness, guilt, ill health, and poverty, impacting the depressive narrative.
  • Persecutory Delusions: Patients may feel targeted, often believing they deserve it.

Atypical Depression

  • Characterized by mood reactivity, overeating, oversleeping, and pronounced anxiety, leading to complex interpersonal dynamics and treatment challenges.
  • Historically associated with poor tricyclic antidepressant response, but modern treatment efficacy remains equivocal.

Mixed Depression

  • Recognizes overlapping depressive and manic symptoms in major depression; DSM-5 allows specification of 'mixed features.'

Mild Depressive States

  • Presentation mirrors more severe forms but typically with less intensity, involving neurotic symptoms like anxiety and obsessional elements.
  • Dysthymia: Chronic state lasting 2+ years, characterized by low mood and functional impairment without full depressive episode criteria.

Minor Anxiety-Depressive Disorders

  • ICD-10 includes a category for symptoms not severe enough to classify as distinct disorders.
  • Unspecified Depressive Disorder in DSM-5: Acknowledges distress-related symptoms lacking strict classification, emphasizing primary care relevance.

Clinical Presentation

  • Minor anxiety-depressive disorders can present with varied symptoms and pose significant classification challenges, requiring consideration in general practice settings.
