Psychopathology
and
Treatment
Definition


Psychopathology
 Clinical term
 A disorder of the mind that interferes with
everyday functioning
Insanity
 Legal term
 Definition has changed over time
 Mental illness or defect decreased the individual’s
capacity to appreciate the criminality of their
behavior or to conform to the law
Diagnosis


Categorical vs Dimensional Diagnosis?
Categorical



Set of symptoms that vary together
Must meet minimum threshold (e.g., 4 or more
symptoms out of 9), to have the disorder
Dimensional


May involve a set of symptoms
Disorder varies in degree of severity (from nonexistent to severe)
Diagnosis

Diagnostic and Statistical Manual of Mental
Disorders IV




Categorical diagnostic system
Specifies sets of observable symptoms for each
disorder
Specifies criteria for having or not having the
diagnosis
Because symptoms of different disorders overlap,
gives information for differential diagnosis
Diagnosis
Anxiety Disorders
Anxiety Disorders

Characterized by the experience of excessive anxiety
in the absence of true danger and avoidance behavior


Anxiety is our built-in alarm system  developed
to warn us of a threat and give us the energy to
respond to the threat
Excessive, chronic anxiety without identifiable
cause and that leads to avoidance of nonthreatening stimuli is abnormal
Anxiety Disorders

Phobic Disorders




Generalized Anxiety Disorder
Panic Disorder



Social Phobia
Specific Phobias
With or without agoraphobia
Obsessive Compulsive Disorder
Post-Traumatic Stress Disorder
Panic Disorder
with Agoraphobia
Symptoms


Panic Disorder
 Attacks of terror that are sudden, overwhelming, and
unexpected
 Did not follow situation that naturally elicits anxiety or
in which the individual was the focus of other’s
attention
 Involves fear of dying, of going crazy, or losing
control
With Agoraphobia
 Fear of situations where escape might be difficult or
embarrassing or where help may be unavailable in the
event of an attack
 Individual avoids such situations, goes only if
accompanied, or endures with significant discomfort
Causes

Biological/Genetic

Locus coeruleus is the area of the brain that
perceives novelty  serves as an alarm system

Abnormalities of the locus coeruleus result in
increased arousal of the central nervous system

Increased arousal of CNS  increased sensitivity
to internal and external cues signaling threat
Causes

Cognitive Behavioral




Symptoms of anxiety and panic are similar to
symptoms associated with heart attack
Panic-prone people monitor bodily sensations for
symptoms that might signal an attack
Presence of symptoms result in life-threatening
cognitions (catastrophizing)
Increased focus on bodily sensations +
catastrophizing  spiking of anxiety or panic
Causes
Causes

Agoraphobia results from negative
reinforcement




Individuals are fearful of having another panic
attack
Going to places where escape might be difficult or
where it would be embarrassing to have an attack
 increased anxiety
Panic disordered individuals avoid such places
Avoidance avoidance of fear/anxiety 
increased avoidance
Treatment
Panic Disorder with
Agoraphobia
Medication

Anxiolytic medications or tranquilizers





Benzodiazepines (e.g., Valium; Klonapin)
Used for short-term treatment of anxiety
Reduce anxiety and promote relaxation
High degree of addiction potential
Selective Serotonin Reuptake Inhibitors (SSRI)




Primarily for the treatment of depression
Appear to have anxiolytic properties
Can be used for long-term
Though not addictive, can have unpleasant side effects
Behavioral Therapy

Cognitive Behavioral Therapy

Education about biological and learning bases of
panic

Cognitive Restructuring



Identifying anxiety-producing thoughts
Challenging thoughts with accurate information
Substituting calming and empowering thoughts for
anxiety-producing thoughts
Behavioral Therapy

Cognitive Behavioral Therapy
 Relaxation training
Diaphragmatic breathing
 Progressive muscle relaxation


Systematic desensitization
Imaginal exposure
 In vivo exposure

Behavioral Therapy

Systematic Desensitization

Develop fear hierarchy

Expose patient to feared stimuli on hierarchy



Start with a low-fear stimulus
Continue to expose to low-fear stimulus until fear
extinguishes
Move to slightly more feared stimulus only after lowerfeared stimulus is mastered

Mood Disorders
Mood Disorders

Mood disorders reflect extreme
emotions that affect our ability to
function and perform everyday
activities
Mood Disorders

Depressive Disorders (AKA unipolar
depression)  pervasive feelings of sadness



Major Depression
Dysthymia
Bipolar Disorders  radical fluctuations in
mood from sad to elated or irritable



Bipolar I  Major Depression & Mania
Bipolar II  Major Depression & Hypomania
Cyclothymia  Dysthymia & Hypomania
Major Depression
Symptoms









Depressed mood most of the day, nearly every day
Loss of interest/ pleasure in previously enjoyed
activities
Significant weight loss or gain (> 5% of body weight)
Insomnia/hypersomnia
Psychomotor agitation or retardation
Fatigue or loss of energy
Feelings of worthlessness or guilt
Impaired thinking/concentration
Recurrent thoughts of death or of suicide
Causes

Genetic



Twin, family, and adoption studies suggest a
genetic component for depression
Identical twins 4 X more likely to be concordant
for depression than Fraternal twins
Biological


Low levels of norepinephrine  depression
Low levels of serotonin  depression
Causes

Biological (continued)

Circadian rhythms, particularly patterns of
sleeping and waking, are associated with
depression

Seasonal Affective Disorder
 As amount of daylight decreases, level of
depression increases
Seasonal Affective Disorder
Causes

Social/Environmental
 More stressful events
 greater likelihood of
developing depression

Having a close
friendship  mitigates
against the impact of
stressful life events
Causes

Cognitive (A.T. Beck)

Cognitive Triad


Attributions



Depressed people think about themselves, their
situation, and the future in a negative manner
Failures/misfortunes = (internal causes) personal defects
Successes = (external causes) luck
Errors in Logic



Overgeneralizing based on single events
Magnifying the seriousness of events
Taking responsibility for bad events
Causes

Learned Helplessness (Seligman)



People view themselves as unable to control the
negative events in their lives
 Attribute negative events to personal defects
stable and global
 People begin to feel helpless about the ability to
make positive changes
Theory based on animal research
Animals placed in aversive situations that they
could not escape  passive and unresponsive
Treatment
Depressive Disorders
Medication

Early Antidepressants
 Monoamine Oxidase Inhibitors (MAOI)
 Effective for treating depression
 Highly toxic

Tricyclic antidepressants
 Effective for treating depression
 Cause weight gain, sedation, sweating,
constipation, heart palpitations, and dry mouth
Medication

Modern Antidepressants

Selective Serotonin Reuptake Inhibitors (SSRIs)
 e.g., Prozac, Lexapro, Paxil
 Increase serotonin levels by blocking reuptake
 Some also have norepinephrine effects
 Also effective for treating anxiety

Atypical Antidepressants

Bupropion  fewer side effects than other
antidepressants (no sexual side effects)
Behavioral Therapies

Cognitive Therapy

People are depressed because of negative beliefs
about themselves, their situation and the future

Therapy focuses on helping clients
 Recognize when they are thinking negatively
 Identify the negative thoughts/beliefs
 Challenge the beliefs with more positive and
adaptive thoughts and/or behavioral
experiments
Cognitive Therapy

Disorder
Behavioral

Dialectical Behavior Therapy (DBT)

Combines elements of behavioral, cognitive, and
psychodynamic approaches

Involves both group and individual therapy
sessions

Begins with a discussion of what is expected of the
client and what can be expected of the therapist
Dialectical Behavior Therapy

Three Stages of Treatment




Stage 1  extreme symptoms (i.e., self-injurious and
suicidal behaviors) are replaced with more
effective/acceptable coping strategies
Stage 2  explore and address traumatic experiences
Stage 3  works on development of self-respect and
independent problem-solving
learn to support and validate themselves rather than
relying on others
