Risk & Protective Factors
Biological Theory and Treatment • low levels of serotonin and norepinephrine • permissive hypothesis: when serotonin levels are low, other neurotransmitters can range more widely
Anti-depressants tricyclic - prevents reuptake of norepinephrine and serotonin (e. g. , Imipramine, Amitriptyline) SSRI - (selective serotonin reuptake inhibitor) blocks the reuptake of serotonin (e. g. , Prozac) MAO inhibitors - elevate level of norepinephrine and serotonin by blocking deactivating enzyme (e. g. , Nardil)
Electroconvulsive Therapy (ECT): shock is delivered to the brain transcranial magnetic stimulation: magnetic coil delivers electromagnetic pulse to the brain.
Cognitive Theories and Treatment Depressive Cognitive Triad (Beck, 1967): 1) self 2) world 3) future
Interpersonal Psychotherapy (IPT) Depression stems from problems in relationships. We develop cyclical maladaptive patterns (CMPs) of relating to others from our interaction with others. These patterns get played out in adult relationships including with therapist. Therapy seeks to identify and treat these CMPs.
