PIPC® Psychiatry In Primary CareANXIETY DISORDERS Robert K. Schneider, MD Departments of Psychiatry, Internal Medicine and Family Practice The Medical College of Virginia at the Virginia Commonwealth University Richmond, Virginia
PIPC®Goals • Effectively recognize, diagnose and treat mental illness in primary care • Bring the psychiatry skills and knowledge base of the primary care physician on par with other medical specialty knowledge bases
Outline • PIPC 1 • Introduction • PIPC®Interview • MAPS-O® • Mood Disorders • Suicide
Outline • PIPC 2 • Anxiety Disorders • PIPC 3 • Neurotransmitters • The 3 Phases and the 5Rs • Medications • Cases and Discussion
Normal vs. Pathological Anxiety • A biological warning system that is activated by perceived danger • Distressing and usually associated with bodily discomfort • Normal levels prepare one for a protective response • High levels can be disorganizing, counter–productive, and cause impairment • Abnormal when disproportionate to the potential for harm or when it occurs in situations reasonably deemed to be harmless
Importance Of Anxiety Disorders as a Group • Are the most common mental disorders • lifetime prevalence for any AD is 24.9% • Tend to be chronic (more chronic and non-remitting than major depression) • Have substantial comorbidity • Carry a burden of distress and impairment similar to chronic medical disorders
Comorbidity Comorbidity is the rule • Depressive disorders (50-70%) • Substance abuse • Other anxiety disorders • Comorbidity predicts: • chronicity, disability, increased suicide risk, and poorer treatment response
Risk Factors • Female gender: F:M~2:1 (except OCD M=F) • Familyhistory: Odds ratios 4-6 • Trauma (abuse, assault, accidents, etc.) • Stressful Life Events (unemployment, illness, death of loved one, marital conflict, etc.) • Note: These are the same risk factors seen in Major Depression - whenever you consider someone at increased risk for depression, they are also at increased risk for an AD
