Neurotransmitters The Serotonin Connection Endocrine Function Elevated Cortisol Dexamethasone Suppression Test: cortisol suppressed in non-depressed people, not in severely depressed.but.
Sleep and Circadian Rhythms Sleep Disturbances are CommonMore intense and earlier start to REM Sleep among the Depressed Diminished Deep Sleep Disruption of Circadian Rhythms

In the United States: About 30,000 Kill Themselves AnnuallyMore Die from Suicide Each Year Than Homicide (about 20,000)More Common Among Whites, Native Americans Increasing in Adolescents (3rd leading cause of death) & Elderly (globally, the elderly have highest suicide rate, esp. males) Males > Females in Killing Themselves Females > Males in Attempts
Approximately 500,000 people each year require ER treatment as a result of attempted suicide Suicidal behavior typically occurs in the presence of mental illness or substance use disordersFirearms account for 59% of all suicide deaths Website of Extreme and Urgent Interestsuicidology.org
Medications Tricyclic Antidepressants Imipramine (Tofranil) Amitriptyline (Elavil) Block Neurotransmitter Reuptake Side Effects
Medications MAO Inhibitors Block Enzyme MonoAmine Oxidase The Result? More Neurotransmitter is Available Side Effects and Complications
Medications SSRIs Block Reuptake of Serotonin- Prozac SSNRIs
Medications - Bipolar Lithium, Depakote, LamictalEffective for Manic Episodes Lithium Must be Carefully Regulated Other Medical Treatments Electroconvulsive Therapy (ECT)TMS
Psychological Interventions Combined Treatments?
*The gender disparity in depression diagnoses worldwide, expressed asodds ratios. These odds ratios express the comparative likelihood of women experiencing amajor depressive episode in the past year, relative to men. In Brazil, for example, women are2.6 times more likely than men to report having had a major depressive episode in the lastyear. (Adapted from Bromet et al. [2011], p. 11 of 16.)
