Majority of manic episodes have psychotic symptoms
Difference between mania and hypomania
Unlike mania, hypomania…
- only lasts at least 4 days (unlike 7)
- does not cause significant impairment
- does not need hospitalization
- does not usually present with psychotic symptoms
Mixed features mood criteria?
Criteria met for either manic/hypomanic episode along with at least 3 symptoms of major depressive episode are present for majority of time. Symptoms must be present every day for at least one week.
T/F: Mood disorders often have chronic courses that are marked with abrupt changes between moods and periods of normal functioning are rare.
False. Mood disorders have chronic courses marked with relapses with relatively normal functioning between episodes

What can cause depression?
MULTI FACTORIAL DISEASE
- underlying theory: NT abnormalities (decreased catecholamines, decreased CSF levels of 5-HIAA serotonin metabolite
- high cortisol
- abnormal thyroid axis
- psychosocial life events (esp if there were multiple adverse events during childhood)
- genetics: increased risk 2-4 times if first degree relative with MDD

What are some adjunct medications for depression?
- atypicals! First line for MDD with psychotic features, also useful in refractory/resistant MDD with or without psychotic features
- Lithium, T3/T4 useful in augmenting treatment of refractory MDD
