Anxiety
 What
is anxiety?
Anxiety


Anxiety: A state characterized by
negative affect, bodily tension, arousal
and apprehension about the future.
Is anxiety always a bad thing?
Fear
 Fear:
Distress about a specific dangerous
object or situation. It is caused by need
for immediate action and is usually shortlived.
 Protects us by triggering the “fight or flight”
response.
Anxiety Disorders
 All
anxiety disorders can be thought of as
extremely exaggerated versions of normal
feelings such as fear, anxiety and panic.
Case Study: Neal

Neal is a 32 year-old IT specialist. He reports
that for the past 18 months he constantly feels
keyed-up, and unable to relax. He worries about
everything, from his health, to the economy, to
whether he is a good enough husband. He feels
emotionally and physically exhausted. Even
though he is worn out, he can’t sleep. He often
spends hours in bed at night ruminating about
possible disasters or things he might have done
to offend people at work. He is having problems
focusing at work, and is afraid he is going to be
fired because of it.
Generalized Anxiety Disorder
(GAD)

DSM-IV Criteria:



Excessive anxiety & worry most days for at least 6
months, related to numerous areas of life.
Difficult to control the worry.
3 or more symptoms:
•
•
•
•
•
Restlessness/feeling “keyed up”
Easily fatigued
Problems concentrating, mind going blank
Muscle tension
Sleep problems
Prevalence of GAD
 Past-year
prevalence is about 2%.
 Lifetime prevalence is about 5%.
 More common in women than men.
 Rate is 2x higher in very low income
groups.
Course of GAD
 Gradual
onset typically in late teens or
early adulthood.
 Tends to be persistent if not treated.
Etiology of GAD

Mildly heritable.
 May be related to chronic activation of the
behavioral inhibition system (BIS).

The BIS causes us to freeze, feel anxious and
nervously evaluate the environment to find the threat.
“Kindling Effect”: Groups of neurons that fire
often have lower activation thresholds, and fire
more easily in the future.
 Fear leads to fear.

Treatment of GAD
 Cognitive-Behavioral



Therapy (CBT):
Superior to medication, long lasting effects.
Learn to identify and control anxious thoughts.
Progressive muscle relaxation.
Case Study: Ally

Ally is a 42 year-old preschool teacher. In the
last year she has been experiencing “spells” that
last about 10 minutes. She gets short of breath,
her heart races, she feels dizzy, her fingers and
toes tingle and she experiences fear that she is
losing her mind. They “come out of the blue.”
She went to the emergency room during her last
spell because she thought she was having a
heart attack. The doctor said she was
healthy, and referred her to see a
therapist.

Prevalence of Panic Disorder

Prevalence is 3.5%

 Prevalence similar across U.S. ethnic
groups.
Course of Panic Disorder
 Onset
in early adulthood, mean age is
25-29.
 Panic attacks don’t usually occur before
puberty.
Etiology of Panic Disorder
 Due
to an interaction of psychological and
biological factors.
 Some people are genetically predisposed
to panic—they have an easily triggered
“fight or flight response”.
 Seem to be more likely to catastrophically
interpret bodily sensations.
Etiology of Panic Disorder
 Upon
the experience of such panic,
psychological factors determine whether
they expect subsequent attacks.
 Agoraphobia is socially or culturally
determined after someone has a panic
attack.
Treatment of Panic Disorder
 Psychological
Treatment:
 Panic Control Therapy


relaxation.

situations.
Case Study: Lucy

Lucy is a 19 year-old college student. Two
months ago, she was raped by her ex-boyfriend
in a car after a football game. Since the rape,
she can’t stop thinking about what happened.
She has nightmares about it, and sometimes
feels as though she is in the back of the car
again. Whenever she sees a car like the one
her ex-boyfriend drives she experiences
paralyzing fear. She finds that he is having
trouble sleeping, and constantly feels on edge,
like she needs to be scanning the room for men
who might try to harm her.

three “Hail Mary” prayers and performs a discreet finger
tapping ritual. If he does not say the prayers perfectly or
tap his fingers evenly and without error he has to start
