This document provides information on various anxiety disorders. It begins by defining anxiety, fear, and panic attacks. It then outlines the five major types of anxiety disorders according to the DSM-IV: generalized anxiety disorder, panic disorder, phobias, posttraumatic stress disorder, and obsessive-compulsive disorder. For each disorder, it discusses characteristics, diagnostic criteria, epidemiology, causes, and treatments. It also compares and contrasts anxiety and fear, and defines the different types of phobias and panic attacks.

2. Out lines
 Introduction
 Define the following terms
Anxiety, fear, & panic attack
Five major types of anxiety disorders are:
 Generalized anxiety disorder
 Panic disorder
 Phobias,
 Posttraumatic stress disorder (PTSD),
 Obsessive–compulsive disorder (OCD),
 Conclusion
 Reference

3. Introduction
 Everyone experiences feelings of anxiety during their
lifetime. For example, the person may feel worried
and anxious about sitting an examination, or having a
medical test, or a job interview. Feeling anxious
sometimes is perfectly normal. However, for people
with generalized anxiety disorder (GAD), feelings of
anxiety are much more constant, and tend to affect
their day-to-day life. However, anxiety is not always
pathological or maladaptive: it is a common emotion
along with fear, anger, sadness, and happiness, and it
has a very important function in relation to survival.

4. Anxiety
 Anxiety is a physiological state characterized by
cognitive, somatic, emotional, and behavioral
components. These components combine to create the
feelings that are typically recognize as fear,
apprehension, or worry.
Or
 Anxiety is a negative mood state characterized by
bodily symptoms of physical tension, & apprehension
about the future (American psychiatric association,
1994; Barlow, 2002)

5. Symptoms of anxiety
 Anxiety is often accompanied by physical sensations
such as:
Sympathetic nervous system (fight)
 heart palpitations
 chest pain
 shortness of breath
 headache.
 Papillary dilation

6.  nausea
 pale skin
 sweating
 trembling,
 stomach aches
 diarrhea, & chills.

7.  Emotionally, anxiety causes a sense of fear or panic
 The cognitive component entails expectation of a
diffuse and certain danger.
 Behaviorally, both voluntary and involuntary
behaviors may arise directed at escaping or avoiding
the source of anxiety and often maladaptive, being
most extreme in anxiety disorders.

8. Anxiety versus Fear
Anxiety is a future oriented mood state, characterized
by apprehension because one cannot predict or control
upcoming events(subjective feeling)
Fear is an immediate and current reaction to danger
characterized by a strong escapist action (objective
feeling)

9. Panic Attack
 An abrupt experience of intense fear or acute
discomfort accompanied by physical symptoms that
include:-
 Heart palpitations
 Chest pain
 Shortness of breath
 Dizziness
 Disorganized personality &
 Not able to make decision.

10. Three basic types of Panic Attacks are describe in DSM-IV
– Situationally bound (cued) panic attack.
are more common in specific phobias or social phobia
– Unexpected (uncued) panic attack
"SPONTANEOUS", Without apparent stimulus.
– Situationally predisposed panic In between
Increased in certain situations (e.g. driving; crowds)

11. The Phenomenology of Panic
Attacks
Figure 1.1 The relationships among anxiety, fear, and panic attack.

12. Anxiety Disorders
Anxiety disorders are the most common of emotional
disorders.
Many forms and symptoms may include:
 Overwhelming feelings of panic and fear
 Uncontrollable obsessive thoughts
 Painful, intrusive memories
 Recurring nightmares
 Physical symptoms such as feeling sick to the
stomach, “butterflies”, heart pounding, and muscle
tension

13.  Anxiety disorders differ from normal feelings of
nervousness.
 Untreated anxiety disorders can push people into
avoiding situations that trigger or worsen their
symptoms.
 People with anxiety disorders are likely to suffer
from depression, and they also may abuse alcohol and
other drugs in an effort to gain relief from their
symptoms.
Job performance, school work, and personal
relationships can also suffer.

14. Psychological Contributions to Anxiety and Fear
• Psychological Views
– Early experiences with uncontrollability / unpredictability
• Began with Freud
– Anxiety is a psychic reaction to danger
– Anxiety involves reactivation of an infantile fearful situation
• Behavioristic Views
– Anxiety and fear result from classical and operant
conditioning and modeling
• Social Contributions
– Stressful life events trigger vulnerabilities
– Many stressors are familial and interpersonal

15. An integrated Model
• Integrative View
– Biological vulnerability interacts with psychological,
experiential, and social variables to produce an anxiety
disorder
• Generalized biological vulnerability to anxiety is not
anxiety itself ,a given stressor could activate biological
tendencies to anxiety and psychological tendencies to
feel that not be able to deal with situation and control
the stress

16. Comorbidity of anxiety disorders
The co-occurrence of two or more disorders in a single
individuals is referred to as Comorbidity.
If each patient with an anxiety disorder also had every
other anxiety disorder, there would be little sense in
distinguishing among the specific disorders.
It would be enough to say, simply, that the patient had
an anxiety disorder.

17. Cont.
But this is not the case, & although rates of Comorbidity
are high, they vary somewhat from disorder to
disorder.
A large-scale study was recently completed at one of our
centers, examining the Comorbidity of DSM IV
anxiety & mood disorders substance abuse disorders,
other anxiety disorders (except Social Phobia)

18. Types of Anxiety Disorders
 Generalized Anxiety Disorder
 Panic Disorder with and without Agoraphobia
 Specific Phobias
 Social Phobia
 Posttraumatic Stress Disorder
 Obsessive-Compulsive Disorder

19. Generalized anxiety disorder
 Generalized anxiety disorder is a common chronic
disorder that affects twice as many women as men and
can lead to considerable impairment (Brawman-
Mintzer & Lydiard, 1996, 1997).

 Fail to process emotional component of thoughts &
Images.

22.  Generalized Anxiety Disorder: The “Basic”
Anxiety Disorder

30. Phobia
A phobia is excessive and persistent fear of a specific
object, situation, or activity.
These fears cause such distress that some people go to
extreme lengths to avoid what they fear.

31. There are three types of phobias:
1. Specific phobia
2. Social phobia
3. Agoraphobia

32. Specific Phobias:
• Overview and Defining Features
– Extreme and irrational fear of a specific object or
situation
– Markedly interferes with one's ability to function
– Recognize fears are unreasonable
– Still go to great lengths to avoid phobic objects

33. Causes of Phobias

something will happen to parents

specific phobia

 Marked & persistent fear that is excessive or
unreasonable, cued by the presence of a specific object
or situation (flying, heights, animals, receiving
injection, seeing blood)
 Exposure to be the phobic stimulus almost invariably
provokes an immediate anxiety response, which may
take the form of a situational bound or Situationally
predisposed panic attack
 The person recognized that the fear is excessive or
unreasonable.

– Direct conditioning, observational learning, information
transmission
