Anxiety Disorders Flashcards
Anxiety
Definition
-
A diffuse, unpleasant, vague sense of apprehension often accompanied by autonomic sx
- Palpitations, tightness in chest, sweating, muscle tension, diarrhea, tingling in extremities
- One of the most prominent sx of psychological discomfort
- “Anxiety” has played a central role in psychodynamic theory
- Most behavior theorist have focused on therapies for reducing anxiety
Physiological Role of Anxiety
- Anxiety is an alerting signal which warns of impending danger
- Important for survival & evolution
- Fear is a response to a known, external, definite, or nonconflictual threat
- Anxiety can be adaptive

Theories of Anxiety
- Is anxiety peripheral in origin or is it central?
- James-Lange: Anxiety is bottom-up (peripheral)
- Cannon-Bard: Emphasis on roles and beliefs in development of anxiety (central)
-
Psychoanalytical Theories:
- Anxiety was described by Freud to be a signal of threat to the ego
- These signals are solicited because current events have similarities, actual or symbolic, to threatening developmental experiences
- Repression is most common defense mechanism against threats to ego.
- When repression doesn’t work, anxiety occurs
-
Behavioral Theories:
- Classical Conditioning
- Social Learning
- Cognitive Theories
-
Existential Theories
- Living in a purposeless universe w/ anxiety being a response to the perceived void in existence and meaning
- Biological Theories
Anxiety Disorders
Features
-
Common feature of all anxiety disorders:
- Marked fear and anxiety
- Specific thoughts associated w/ these sx
- Sx are disproportionate and persistent
- There is distress and impairment
- Anxiety disorders differ from each other in the types of situations that induce fear, anxiety, or avoidance behavior and the associated cognitive ideation
Psychiatric Illnesses
Associated w/ Anxiety
- Mood disorders
- Schizophrenia
- OCD
- Stress‐related disorders
- Dissociative disorders
- Eating disorders
- Somatic Symptom disorders
Anxiety Disorders
Epidemiology
- Anxiety and related disorders are among the most common psychiatric disorders
- Lifetime prevalence rates as high as 31%
- 12‐month prevalence rates of about 18%
- Significant costs in terms of healthcare use, loss of workforce productivity, disability, and quality of life
- Most patients w/ Anxiety Disorders present to their PCP
- Detection of anxiety disorders often poor
- Effective management for each of the anxiety disorders is available, but currently underused, leaving patients in a less‐than‐optimally treated state

Separation Anxiety Disorder
-
Seen in childhood
- Can be expressed throughout adulthood as well
- Fearful or anxious about separation from attachment figures to a degree that is developmentally inappropriate

Obsessive–compulsive disorder (OCD)
Definition
Common, disabling psychiatric disorder characterized by:
-
Obsessions
- Recurrent and persistent thoughts, images, or urges
- Experienced, at some time, as intrusive and unwanted
- Cause marked anxiety or distress

- Types of Compulsions: Yielding, Controlling
OCD
Etiology
-
Biological factors:
- Genetic predisposition likely
-
Dysregulation of 5-HT is involved in the sx formation of obsessions and compulsions in the disorder
- SSRI’s are most effective in tx OCD
- Link between GAS strep infection and OCD
- Altered function in the neurocircuitry between orbitofrontal cortex, caudate, and thalamus
-
Psychological:
- Psychoanalytic theories view OCD as a regression to the anal stage
- Learning Theory:
- Obsessions are conditioned stimuli ⇒ neutral objects and thoughts become conditioned stimuli capable of provoking anxiety or discomfort
- Compulsions are reinforced ⇒ ritualistic behaviors reduce the anxiety
-
Developmental factors:
- Emotional, physical, and sexual abuse or neglect, social isolation, teasing, or bullying
- Other stressors include pregnancy and the postnatal period
