mood WITHOUT abnormally high mood periods
Depressive Disorders
> 1 major depressive episode (MDE) and cannot have a history of mania or hypomania (never swings to opposite mood)
Major Depressive Disorder
unipolar depression
Major Depressive Disorder
2 weeks of >5 affective, neuro-vegetative, or cognitive symptoms
Major Depressive Episode
Affective symptoms of MDE
depressed mood
anhedonia (lack of pleasure)
Neuro-vegetative symptoms of MDE
significant weight change
in/hypersomnia
loss of energy
Cognitive symptoms of MDE
psychomotor changes
feeling guilty/worthless
decreased concentration
thoughts of death/suicidal ideation
Risk of developing MDD
gen. pop. = 10%
relative (1st degree) = 20%
MZ co-twin with MDD = 30%
MDD Neurobiology
^ Amygdala
^ HPAA
^ Cortisol
^ Cytokines
v Hippocampus
v Prefrontal Cortex
v Monoamines (dopamine & serotonin)
psychotherapy (CBT) and antidepressants (^ serotonin and norepinephrine)
MDD treatments
most popular class of ADs with benign side effects (ex: Fluoxetine AKA Prozac)
SSRIs
not as affective as SSRIs but also has benign side effects
ex: Venlafaxine AKA Effexor
SNRIs
Serotonin and Norepinephrine reuptake inhibitors, less serotonin and more norepinephrine, cardiac side effects
TCAs (Tricyclic Antidepressants)
prevent enzyme degradation, diet restrictions to avoid tyramine-induces hypertension
MAOIs
must experience at least 1 maniac episode, symptoms >1 wk (or hospitalization) that case marked impairment in functioning,
Bipolar I Disorder (BPI)
abnormally elevated mood (or irritability) PLUS increased energy and 3 additional symptoms
Manic Episode
Manic episodes without MDE (uncommon)
Manic episodes with alternating MDE (common)
BPI
Risk of developing BPI
gen. pop. = 1%
relative (1st degree) = 20%
MZ co-twin with BPI = 80%
more genetically controlled than MDD and manic episodes involve increased monoaminergic activitiy
BPI
Mood stabilizer: treatment of Manic Episodes
lithium
anticonvulsants
antipsychotics
treatment of bipolar MDEs
antidepressants with mood stabilizer
ONLY FDA-approved drugs for BP depression
antipsychotics (different for those used to treat mania)
experiencing at lease 1 MDE and 1 hypomanic episode
Bipolar II Disorder
does not cause marked impairment in function, changed of mood uncharacteristic of person and last >4 days
Hypomanic episode
