Study Notes

Anxiety as a Pathophysiological State

Anxiety is a pathophysiological state that impairs normal function and likely hinders an organism's success.
Fear is a normal physiological response for survival, characterized by heightened sensory state, vigilance, and the fight-or-flight response.
Anxiety is distinguished from fear by an overly-reactive, non-adaptive activation of physiological responses that detract from normal function and likely hinder an organism's success.

Anxiety Disorders Classification and Complexity

Anxiety disorders are complex, encompassing a range of symptoms and varying degrees of severity.
Current classification systems (DSM-IV/V) describe specific anxiety disorders, such as panic attacks, agoraphobia, panic disorder, specific phobias, social phobias, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and acute stress disorder.
Anxiety disorders are often comorbid with other conditions (e.g., substance abuse).
Diagnostic criteria often include symptom specifications (e.g., palpitations, choking sensations, fear of losing control, etc.) and durations that should peak in 10 minutes.
Co-existing conditions, such as agoraphobia, may present as recurrent panic attacks.

Fear Pathway and Neurobiology

The fear pathway is a template for understanding anxiety.
Fear is a response to immediate danger, while anxiety is associated with chronic, anticipatory danger and often involves cognitive interpretations.
The amygdala plays a crucial role in the fear pathway, receiving inputs from various regions, including the sensory cortex, hippocampus, and thalamus.
The amygdala interacts with other brain regions like hypothalamus and prefrontal cortex to process and modulate fear responses.
Neurobiological models highlight how learning and experience (neural plasticity) shape the fear response and contribute to anxiety pathophysiology.

Anxiety Pharmacotherapy

Current treatment emphasizes serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, benzodiazepines (acting on GABA receptors), and other medications.
Benzodiazepines are a rapid-acting class of anxiolytic.
Different anxiety disorders respond variably to treatments like SSRIs or tricyclic antidepressants.
Some anxiety disorders have an increased co-morbidity with mood disorders, hence the need for tailored treatment approaches.

Non-drug Therapies for Anxiety

Various non-drug approaches, like psychoanalysis, mindfulness, cognitive behavioral therapy (CBT), and family therapy, show varying efficacy in anxiety management, and there is evidence for brain changes with some therapeutic practices (e.g.meditation leading to changes in brain state).
Approaches address underlying psychological themes and cognitive distortions to modify learned behaviors and thoughts linked to anxiety.

General Considerations

Neuropharmacological understanding of affective disorders is still debated and incomplete, with some widely used medications showing limited benefit, despite widespread use.
