*Mini-lecture 1 : The structure of mood disorders
The structure of mood disorders
 Characterized mood disorders: "Normal" mood (euthymia)
o Moods will fluctuate within a "normal" range (good days vs. bad days)
o Individuals' baseline mood may vary, but no significant distress or
impairment

 Characterized mood disorders: depression (low mood)
o Emotional states: Persistently sad; tearfulness; irritability; jumpiness;
hopelessness
o Motivation: unmotivated; reduced social activity; anhedonia
o Functioning: Move or talk slower than normal; changes in sleep or appetite
o Cognition: Difficulty concentrating; worthlessness; guilt; feelings of
inadequacy

 Characterized mood disorders: Mania (extreme high mood)
o Emotional states: Inflated self-esteem; grandiosity; irritability
o Motivation: Need for constant excitement/activity; activities with high
potential for consequences
o Functioning: High energy levels (little/no sleep); rapid speech and
movements
o Cognition: Lack of planning judgement; racing thoughts; distractibility
