Affective disorders - clinical aspects Flashcards
What is psychopathology
- Abnormal experience, cognition and behaviour
What is descriptive psychopathology
- describes and categorizes the abnormal experiences as reported by the patient and observed in behaviour
Classification of descriptive psychopathology
- Observation of behaviour
- Phenomenology
What is phenomenology
- Emphatic assessment of subjective experience
Standard sets of criteria used to classify al psychiatric disorders
- The diagnostic and statistical manual for mental disorders(DSM)
- The international classification of diseases(ICD)
Psychiatric examination
· Presenting symptoms and their chronology
· The psychiatric history
· Mental state examination
· Diagnosis
MDE - Appearance and behaviour
- clothing, posture, gestures, gaze, attitude towards examiner, motor retardation, agitation (hand wringing, hair pulling), stooped posture, downcast gaze, catatonic features
MDE - Speech
- Decreased rate and volume, delayed response, spontaneity
MDE - Mood, affect
- Depression, anhedonia, reactivity of mood, anxiety, panic
MDE - Expression
- Mood congruence
MDE - Thoughts
Form (thought blocking, slow flow of thoughts, associations maintained); Content (poverty of contents, non-delusional ruminations about loss, death, suicide,etc.); mood-congruent delusions (guilt, punishment)
MDE - Perception
- Mood congruent hallucinations(rare)
MDE - Cognition
- Oriented to person, place and time, memory and concentration impairment
MDE - Judgement and insight
- Excessive, or poor
The affective episodes
- Major depressive episode
- Manic episode
- Hypomanic episode
- Mixed affective episode
Symptoms of depression
· Depression of mood · Anhedonia · Psychomotor retardation · Agitation / restlessness · Anxiety / preoccupation · Diurnal variation of mood · Insomnia · Feelings of guilt , self-reproach worthlessness · Somatic symptoms · Hypochondriasis · Weight loss · Suicidal thoughts
Major depressive episode - DSM V criteria
Five of more symptoms during 2 weeks period:
- Depressed mood most of the day, nearly every day
- Diminished interest or pleasure
- Weight loss / weight gain or appetite decrease / increase
- Insomnia or hypersomnia
- Psychomotor agitation or retardation
- Fatigue or loss of energy
- Feelings of worthlessness or excessive or inappropriate guilt
- Diminished ability to think or concentrate, or indecisiveness
- Recurrent suicidal ideation or a suicide attempt/plan
What do symptoms of major depressive episode - DSM V criteria cause
- Symptoms must cause clinically significant distress or functional impairment and are not attributable to the physiological effects of a substance or to another medical condition
Melancholic features of major depressive episode - DSM V criteria
Loss of pleasure in all, or almost all, activities
Lack of reactivity to usually pleasurable stimuli
Profound despondency, despair, empty mood
Depression regularly worse in the morning
Early-morning awakening
Marked psychomotor agitation or retardation
Significant anorexia or weight loss
Excessive or inappropriate guilt
Features of atypical depression
• Mood reactivity
and
• Significant weight gain or increase in appetite
• Hypersomnia
• Leaden paralysis (i.e., heavy, leaden feelings in arms or legs)
• interpersonal rejection sensitivity
Features of the manic episode - DSM V diagnosis
- abnormally and persistently elevated, expansive, or irritable mood
- For a period lasting at least one week and present most of the day, nearly every day:
- abnormally and persistently increased activity or energy

Effect of manic episode on functional capabilities
- The mood disturbance is sufficiently severe to cause marked functional impairment or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features
- The episode is not attributable to the physiological effects of a substance or to another medical condition.
- Can be associated to psychotic symptoms such as delusions and hallucinations
Features of the hypomanic episode - DSM V diagnosis
For a period lasting at least 4 days and present most of the day, nearly every day:

- Decreased need for sleep
- More talkative than usual or pressure to keep talking
- Flight of ideas or racing thoughts
- Distractibility
- Increase in goal-directed activity or psychomotor agitation
- Excessive involvement in high risk activities
Effect of a hypomanic episode - DSM V diagnosis on functional capabilities
- The episode is not severe enough to cause marked functional impairment or to necessitate hospitalization
- The episode is associated with an unequivocal change in functioning that is uncharacteristic of the individual when not symptomatic
- The disturbance in mood and the change in functioning are observable by others.
- The episode is not attributable to the physiological effects of a substance (eg, a drug of abuse, a medication, or other treatment).

Features of bipolar disorder II
- At least one hypomanic episode
- At least one major depressive episode
Peak age onset for bipolar disorder
- 15-24 years old
Prevalence of bipolar disorder
- 0.6-2.4%

Effect of bipolar disorder on men and women
- Both affected equally
General features of bipolar disorder
- Highly recurrent
* May have progressive course
Suicide rate comparison - bipolar disorder and general population
- Rate of suicide > 20 times higher than general population
* 30%-50% of patients attempt suicide
