1 Kelly Kll M. Rock, DNP, CRNP 11/5/11 Objectives: Identify lifetime prevalence of depressive and anxious disorders. Recognize the social and economic burden of depressive and anxious disorders. Understand basic biological etiology of depressive and anxious disorders. Recognize symptoms of and anxiety across the lifespan. Identify appropriate FDA approved treatment modalities to treat depressive and anxious disorders. Lifetime prevalence Depressive disorders Major depressive disorder 16.9% highest of any psychiatric disorder Dysthymia 2.5% Anxious disorders Generalized anxiety disorder 5.7% Panic disorder 4.7% Obsessive compulsive disorder 2.3% National Comorbidity Survey retrieved September 2, 2011 at Social & Economic Burden of Leading cause of disability 4th leading contributor to the global burden of disease 15% of those with commit suicide Burden of crosses all domains of life Personal burden Family burden Mortality burden Disability burden Economic burden Etiology: Biological Factors of & Anxiety Neurotransmitters of interest Until recently, monoamine neurotransmitters (NTs) were the main focus of theories and research (serotonin, norepinephrine, dopamine) There has been a progressive shift in interest in favor of studying neurobehavioral systems, neural circuits and more intricate neuroregulatory mechanisms. 1

Anyone considering the use of [Insert established name] or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. [Insert Drug Name] is not approved for use in pediatric patients.
