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.
