advertisement
ANXIETY
DISORDERS
•A common dimension of day-to-day
human experiences
•An unpleasant emotion
characterized by a feeling of
vague, unspecified harm.
ANXIETY DISORDERS
• Marked by experience of
physiological arousal, apprehension
or feeling of dread, hyper vigilance,
avoidance and sometimes, a specific
fear or phobia
FEAR VS ANXIETY
FEAR
- immediate alarm reaction to danger
- Response to a known, external,
definite or non-conflictual threat
- Response to an immediate threat
ANXIETY
- Negative mood state characterized by
bodily symptoms of physical tension and
by apprehension about the future
- Response to a threat that is unknown,
internal vague or conflictual
- Apprehension about a future threat
ANXIETY DISORDERS
• Primary determination of whether the fear or
anxiety is excessive or out of proportion is
made by the clinician, taking cultural
contextual factors into account.
• Can develop in childhood and persist into
adulthood if not treated
• Most occur in females than males (2:1)
CAUSE OF ANXIETY DISORDERS
• Biological Contributions
- We inherit a tendency to be tense, uptight, and anxious
- Behavioral Inhibition System (BIS):
- Tendency is to freeze
- Activated by signals from the brain stem of unexpected events
that might signal danger.
- Fight/Flight system (FFS):
- Immediate alarm-and-escape response like panic.
Environment can change the sensitivity of these brain circuits.
- Ex: teenage smoking can lead to early GAD or panic disorder
CAUSE OF ANXIETY DISORDERS
Psychological Contributions
• Freud: anxiety was a psychic reaction to danger surrounding the
reactivation of an infantile fearful situation
• “Sense of uncontrollability” / locus of control: higher, more anxious
• Parents’ actions in childhood: Parents’ positive and predictable
responses: less anxious. Negative/ overprotective: more anxious
Social Contributions
• Marriage, divorce, difficulties at work, death of a loved one,
pressures to excel in school
Triple Vulnerability Theory
COMORBIDITIES
Comorbidity: Co-occurrence of two or more disorders in an individual
• Anxiety disorders with depression/ major depression
• Diagnoses of depression or alcohol or drug abuse makes it less likely
to recover from anxiety disorder and more likely to relapse
Physical Comorbidities:
• Anxiety disorder with thyroid disease, respiratory disease,
gastrointestinal disease, arthritis, migraine headaches
• Panic disorders and cardio, respiratory, gastrointestinal, and
vestibular (inner ear) disorders
SUICIDE
- Weissman study: 20% of patients with panic
disorder had attempted suicide
- Anxiety or related disorder increases the chances of
having thoughts about suicide (suicidal ideation) or
making suicidal attempts
- Strongest with panic disorder and posttraumatic stress
disorder

DEVELOPMENT
It can sometime develop:
• After a traumatic event
•Observation of others going through a
traumatic event
•An unexpected panic attack in the feared
situation
•informal transmission
However, many are unable to recall the cause

SOCIAL ANXIETY DISORDER
(SOCIAL PHOBIA)
• Starts in mid-teens
• Duration is life long
• Frequently appears
among first degree
biological relatives
CRITERIA FOR SOCIAL
ANXIETY DISORDER
(SOCIAL PHOBIA)
A. Marked fear or anxiety about one or
more social situations in which the
individual is exposed to possible scrutiny
by others. Exposure to the feared social
situation provokes anxiety
B. The individual fears that he or she will act
in a way or show anxiety symptoms that
will be negatively evaluated
CRITERIA FOR SOCIAL PHOBIA
c. Social situations almost always provoke
fear or anxiety.
d. The social situations are avoided or
endured with intense fear or anxiety.
e. Fear or anxiety is out of proportion to
the actual threat posed by the social
situation and to the sociocultural context.
CRITERIA FOR SOCIAL PHOBIA
f. Persistent and lasting for 6 months or more.
g. the fear, causes clinically significant distress or impairment in
important areas of functioning.
h. Not caused by physiological effects of a substance
i. the fear, anxiety, or avoidance is not better explained by the
symptoms of another mental disorder
j. if another medical condition (e.g., parkinson’s disease,
obesity, disfigurement from bums or injury) is present, the fear,
anxiety, or avoidance is clearly unrelated or is excessive.
SPECIFIERS:
• Performance only:
they have performance fears that impairs in their
professional lives
they do not fear or avoid non-performance
situations.
ASSOCIATED FEATURES

• May be inadequately assertive or
excessively submissive
• May overly show rigid body posture
• May be shy or withdrawn
• Seek employment that does not require
social contract
• Men may be delayed in marrying whereas
women prefer to be homemakers
ETIOLOGY OF SOCIAL PHOBIA

37
PSYCHOLOGICAL TREATMENT OF PTSD
• EXPOSURE TO MEMORIES AND REMINDERS OF THE ORIGINAL TRAUMA
• EITHER DIRECT (IN VIVO) OR IMAGINAL
• TREATMENT MAY INITIALLY INCREASE SYMPTOMS
• MORE EFFECTIVE THAN MEDICATION OR SUPPORTIVE THERAPY
• COGNITIVE THERAPY
• ENHANCE BELIEFS ABOUT COPING ABILITIES
• ADDING CT TO EXPOSURE DOES NOT IMPROVE TREATMENT RESPONSE
• TREATMENT OF ASD MAY PREVENT PTSD
• SHOWS BENEFITS EVEN 5 YEARS AFTER THE TRAUMATIC EVENT
Spectrum Model of Social Phobia and
Avoidant Personality Disorder
PANIC ATTACK
• An abrupt surge of intense fear or intense
discomfort that reaches a peak within minutes
• A panic attack is not a mental disorder
• Can occur in the context of any anxiety
disorder as well as other mental disorders
• When the presence of a panic attack is
identified, it should be noted as a specifier (ex.
“ptsd with panic attacks”).
Uncued / Unexpected attacks
- Occur unexpectedly without
warning
- Panic disorder diagnosis
requires recurrent uncued
attacks.
- Panic Disorders
Cued / Expected attacks
- Triggered by specific situations
(e.g., tunnel, mountain
climbing=heights)
- More likely a phobia
PANIC DISORDER
• Higher risk on women; 2:1 ratio
• Commonly develops in young adults;
• 20 – 24 years old
• 25% unemployed for more than 5 years
because of symptoms
• Prognosis worse when agoraphobia is
present
PSYCHOSOCIAL FACTORS
• Cognitive-behavioral
theories – classical
conditioning
• Psychoanalytic theories –
arise from an unsuccessful
defense against anxietyprovoking impulses.
