Anxiety disorders are characterized by excessive or inappropriate fear or anxiety.
Fear is manifested by a transient increase in sympathetic activity (“fight or flight” physiologic response, thoughts, feelings, behaviors) in a situation perceived to be dangerous or threatening.
Anxiety involves apprehension regarding a future threat.
The criteria for most anxiety disorders involve symptoms that cause clinically significant distress or impairment in social and/or occupational functioning.
Etiology of PTSD: TRAUMA T raumatic event R eexperience A voidance U nable to function M onth or more of symptoms A rousal increased
Cognitive processing therapy is a modified form of cognitive-behavioral therapy in which thoughts, feelings, and meanings of the event are revisited and questioned
Addictive medications such as benzodiazepines should be avoided in the treatment of PTSD because of the high rate of comorbid substance use disorders
Posttraumatic stress disorder (PTSD) stressor = life threatening! Adjustment disorder stressor ≠ life threatening
Anxiety disorders are caused by a combination of genetic, biological, environmental, and psychosocial factors.
Primary anxiety disorders can only be diagnosed after determining that the signs and symptoms are NOT due to the physiological effects of a substance, medication, or another medical condition.
Major neurotransmitter systems implicated in anxiety disorders include norepinephrine (NE), serotonin (5-HT), and gamma-aminobutyric acid (GABA).
Anxiety disorders are the most common form of psychopathology.
Anxiety disorders are more frequently seen in women compared to men, approximately 2:1 ratio.
Assess for psychopathology if an individual’s symptoms are causing Social and/or Occupational Dysfunction (SOD).
Treatment of anxiety disorders involves determining the severity of symptoms and initiating psychotherapy for mild anxiety.
Consider a combination of therapy and medication for moderate to severe anxiety.
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are first-line medications for anxiety disorders.
Benzodiazepines work quickly and effectively, but regular use results in dependence.
Minimize the use, duration, and dose of benzodiazepines.
Generalized anxiety disorder (GAD) is characterized by excessive, anxiety/worry about various daily events/activities for at least 6 months.
GAD is associated with difficulty controlling the worry and ≥3 symptoms: restlessness, fatigue, impaired concentration, irritability, muscle tension, insomnia.
Symptoms of GAD are not caused by the direct effects of a substance, or another mental disorder or medical condition.
Symptoms of GAD cause significant social or occupational dysfunction.
The lifetime prevalence of GAD is 5-9%.
GAD rates are higher in women compared to men (2:1).
One-third of the risk for developing GAD is genetic.
The median age of onset of GAD is 30 years.
The course of GAD is chronic, with waxing and waning symptoms.
Patients with GAD are often described as worriers.
Typical associated symptoms of GAD include insomnia, fatigue, and impaired concentration.
Symptoms of GAD have been present for over 6 months.
A complete physical exam and medical workup should be performed to rule out other medical conditions or substance use contributing to or causing the patient’s anxiety symptoms.
Treatment options for GAD include psychotherapy (usually CBT) and pharmacotherapy (typically SSRIs).
A combination of both modalities may achieve better remission rates than either treatment alone.
For patients with anxiety, evaluate for caffeine use and recommend significant reduction or elimination.
Exercise can significantly reduce anxiety.
The worries associated with GAD are free-floating across various areas, as opposed to being fixed on a specific trigger.
Rates of full remission are low for GAD.
GAD is highly comorbid with other anxiety and depressive disorders.
The most effective treatment approach for GAD combines psychotherapy and pharmacotherapy: CBT, SSRIs (e.g., sertraline, citalopram) or SNRIs (e.g., venlafaxine).
