Causes of Panic Disorder •Biological Theories •Genetic (30-40% contribution) •Human studies (families; twins) •Rodent studies (stathmin gene may contrib to fear and anxiety) •Neurotransmitter contributions •Poor regulation of norepinephrine, serotonin, and perhaps GABA in the locus ceruleus and limbic systems Chapter 7 •Kindling Model (next slide) Copyright © 2007 by The McGraw-Hill Companies, Inc.

Kindling Model of Panic Disorder Poor regulation in locus ceruleus Panic Attacks Lowers threshold for chronic anxiety in limbic system Chronic anxiety increases likelihood of dysregulation in locus ceruleus Panic Attacks Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Causes of Panic Disorder (cont.) Cognitive Factors – People prone to panic attacks – (1) pay very close attention to their bodily sensations – (2) misinterpret these sensations – (3) engage in snowballing, catastrophizing thinking Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc.

They act on GABA, which seems to play a role in fear. They generally work quickly, but due to concerns about abuse or dependency, other medications are now more commonly prescribed. Tricyclic antidepressants (TCAs). These medications were developed in the 1950s and 1960s. They help prevent reuptake of 5HT and NE, but they also affect other neurotransmitters and can have serious side effects. They are not as commonly prescribed in the United States as are newer classes of antidepressants. Monoamine oxidase inhibitors (MAOIs). The MAOIs were developed at about the same time as the TCAs, but they are believed to work differently. They seem to stop the brain from breaking down 5HT and NE after reuptake. Selective serotonin reuptake inhibitors (SSRIs). The SSRIs prevent reuptake of neurotransmitters in the brain. Although the various SSRIs seem to work in basically the same way and have similar side effects, people seem to respond differently to different SSRIs. Serotonin-norepinephrine reuptake inhibitors (SNRIs). Developed in the 1990s, Effexor XR® (venlafaxine HCl) was the first SNRI. It works on 5HT, like an SSRI, but also helps prevent reuptake of NE.

The clinician guides clients in identifying the catastrophizing cognitions they have about changes in bodily sensations. 3. Clients practice using their relaxation and breathing exercises while experiencing panic symptoms in the therapy session. Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Cognitive-Behavioral Therapy, continued 4. The therapist will challenge clients’ catastrophizing thoughts about their bodily sensations and teach them to challenge their thoughts for themselves 5. The therapist will use systematic desensitization techniques to gradually expose clients to those situations they most fear while helping them to maintain control Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Generalized Anxiety Disorder (GAD) Excessive anxiety and worry Difficulty in controlling the worry Restlessness or feeling keyed-up or on edge Easily fatigued Difficulty concentrating Irritability Muscle tension and sleep disturbance Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc.

Obsessive-Compulsive Disorder • a chronic anxiety disorder most commonly characterized by obsessive, distressing, intrusive thoughts and related compulsions (tasks or "rituals") which attempt to neutralize the obsessions. Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Obsessions (as defined by DSM-IV-TR) Recurrent and persistent thoughts, impulses, or images that are experienced intrusive and inappropriate and that cause anxiety or distress Thoughts, impulses, or images that are not simply excessive worries about real life problems Thoughts, impulses or images that the person attempts to ignore or suppress or to neutralize with some other thought or action Obsessive thoughts, impulses or images that the person recognizes are a product of his or her own mind Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Compulsions (as defined by DSM-IV-TR), continued Repetitive behaviors (such as hand washing, ordering, checking) or mental acts (such as praying, counting, repeating words silently) that the person feels driven to perform in response to an obsession or according to rules that must be applied rigidly Behaviors or mental acts that are aimed at preventing or reducing distress or preventing some dreaded event or situation; however, these behaviors or mental acts are not connected in a realistic way with what they should prevent Chapter 7 Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Treatments for OCD • Biological Treatments – as before, mostly psychotropic meds • Cognitive-behavioral Treatments – Expose the client to obsessions until anxiety about obsessions decreases, prevent compulsive behaviors and help the client manage anxiety that is aroused. For example, systematic desensitization may be used to help a person with a germ obsession gradually materials.
