Psychological Disorders
I felt the need to clean my room … would spend four to
five hours at it… At the time I loved doing it. Then I
didn't want to do it any more, but I couldn’t stop… The
clothes hung… two fingers apart… I touched my
bedroom wall before leaving the house… I had constant
anxiety… I thought I might be nuts.
Marc, diagnosed with
obsessive-compulsive disorder
(from Summers, 1996)
7
Psychological Disorders
People are fascinated by the exceptional, the
unusual, and the abnormal. This fascination
may be caused by two reasons:
1.
During various moments we feel, think, and act
like an abnormal individual.
2.
Psychological disorders may bring unexplained
physical symptoms, irrational fears, and suicidal
thoughts.
8
Psychological Disorders
To study the abnormal is the best way of
understanding the normal.
William James (1842-1910)
1.
There are 450 million people suffering from
psychological disorders (WHO, 2004).
2.
Depression and schizophrenia exist in all cultures
of the world.
9
Defining Psychological Disorders
Mental health workers view psychological
disorders as persistently harmful thoughts,
feelings, and actions.
When behavior is deviant, distressful, and
dysfunctional psychiatrists and psychologists
label it as disordered (Comer, 2004).
10
Deviant, Distressful & Dysfunctional
Carol Beckwith
1. Deviant behavior
(going naked) in one
culture may be
considered normal,
while in others it may
lead to arrest.
2. Deviant behavior must
accompany distress.
3. If a behavior is
dysfunctional it is
clearly a disorder.
In the Wodaabe tribe men
wear costumes to attract
women. In Western society
this would be considered
abnormal.
11
Understanding Psychological
Disorders
Ancient Treatments of psychological disorders
include trephination, exorcism, being caged like
animals, being beaten, burned, castrated,
mutilated, or transfused with animal’s blood.
John W. Verano
Trephination (boring holes in the skull to remove evil forces)
12
The Medical Model
Philippe Pinel (1745-1826) from France, insisted
that madness was not due to demonic possession,
but an ailment of the mind.
George Wesley Bellows, Dancer in a Madhouse, 1907. © 1997 The Art Institute of Chicago
Dance in the madhouse.
13
Medical Model
When physicians discovered that syphilis led to
mental disorders, they started using medical models
to review the physical causes of these disorders.
1.
2.
3.
4.
Etiology: Cause and development of the
disorder.
Diagnosis: Identifying (symptoms) and
distinguishing one disease from another.
Treatment: Treating a disorder in a psychiatric
hospital.
Prognosis: Forecast about the disorder.
14
The Biopsychosocial Approach
Assumes that biological, socio-cultural, and
psychological factors combine and interact to
produce psychological disorders.
15
Classifying Psychological Disorders
The American Psychiatric Association rendered
a Diagnostic and Statistical Manual of Mental
Disorders (DSM) to describe psychological
disorders.
The most recent edition, DSM-IV-TR (Text
Revision, 2000), describes 400 psychological
disorders compared to 60 in the 1950s.
16
Multiaxial Classification
Axis I
Axis II
Is a Clinical Syndrome (cognitive, anxiety,
mood disorders [16 syndromes]) present?
Is a Personality Disorder or Mental Retardation
present?
Is a General Medical Condition (diabetes,
Axis III
hypertension or arthritis etc) also present?
Are Psychosocial or Environmental Problems
Axis IV
(school or housing issues) also present?
What is the Global Assessment of the person’s
Axis V functioning?
17
Multiaxial Classification
Note 16 syndromes in Axis I

19
Goals of DSM
1.
2.
Describe (400) disorders.
Determine how prevalent the
disorder is.
Disorders outlined by DSM-IV are reliable.
Therefore, diagnoses by different professionals
are similar.
Others criticize DSM-IV for “putting any kind
of behavior within the compass of psychiatry.”
20
Labeling Psychological Disorders
1. Critics of the DSM-IV argue that labels may
stigmatize individuals.
Elizabeth Eckert, Middletown, NY. From L. Gamwell and
N. Tomes, Madness in America, 1995. Cornell University Press.

21
Labeling Psychological Disorders
2. Labels may be helpful for healthcare
professionals when communicating with
one another and establishing therapy.
22
Labeling Psychological Disorders

3. “Insanity” labels
raise moral and
ethical questions
about how society
should treat people
who have
disorders and have
committed crimes.
Theodore Kaczynski
(Unabomber)
23
Anxiety Disorders
Feelings of excessive apprehension and anxiety.
1.
2.
3.
4.
5.
Generalized anxiety disorder
Panic disorder
Phobias
Obsessive-compulsive disorder
Post-traumatic stress disorder
24
Generalized Anxiety Disorder
Symptoms
1. Persistent and uncontrollable tenseness and
apprehension.
2. Autonomic arousal.
3. Inability to identify or avoid the cause of
certain feelings.
25
Panic Disorder
Symptoms
Minutes-long episodes of intense dread which
may include feelings of terror, chest pains,
choking, or other frightening sensations.
Anxiety is a component of both disorders. It
occurs more in the panic disorder, making
people avoid situations that cause it.
26
Phobias
Marked by a persistent and irrational fear of an
object or situation that disrupts behavior.
27
Kinds of Phobias
Agoraphobia
Acrophobia
Claustrophobia
Hemophobia
Phobia of open places.
Phobia of heights.
Phobia of closed spaces.
Phobia of blood.
28
Obsessive-Compulsive Disorder
Persistence of unwanted thoughts (obsessions)
and urges to engage in senseless rituals
(compulsions) that cause distress.
29

30
Post-Traumatic Stress Disorder
Four or more weeks of the following symptoms
constitute post-traumatic stress disorder
(PTSD):
1. Haunting memories
2. Nightmares
3. Social withdrawal
Bettmann/ Corbis
4. Jumpy anxiety
5. Sleep problems
31
Resilience to PTSD
Only about 10% of women and 20% of men
react to traumatic situations and develop PTSD.
Holocaust survivors show remarkable resilience
against traumatic situations.
All major religions of the world suggest that
surviving a trauma leads to the growth of an
individual.
32
Explaining Anxiety Disorders
Freud suggested that we repress our painful
and intolerable ideas, feelings, and thoughts,
resulting in anxiety.
33
The Learning Perspective
John Coletti/ Stock, Boston
Learning theorists
suggest that fear
conditioning leads to
anxiety. This anxiety
then becomes
associated with other
objects or events
(stimulus
generalization) and is
reinforced.
34
The Learning Perspective
Investigators believe that fear responses are
inculcated through observational learning.
Young monkeys develop fear when they watch
other monkeys who are afraid of snakes.
35
The Biological Perspective
Natural Selection has led our ancestors to learn
to fear snakes, spiders, and other animals.
Therefore, fear preserves the species.
Twin studies suggest that our genes may be
partly responsible for developing fears and
anxiety. Twins are more likely to share phobias.
36
The Biological Perspective
S. Ursu, V.A. Stenger, M.K. Shear, M.R. Jones, & C.S. Carter (2003). Overactive action
monitoring in obsessive-compulsive disorder. Psychological Science, 14, 347-353.
Generalized anxiety,
panic attacks, and even
OCD are linked with
brain circuits like the
anterior cingulate cortex.

37
Dissociative Disorders
Conscious awareness becomes separated
(dissociated) from previous memories,
thoughts, and feelings.
Symptoms
1. Having a sense of being unreal.
2. Being separated from the body.
3. Watching yourself as if in a movie.
38
Dissociative Identity Disorder (DID)
A disorder in which a person exhibits two or
more distinct and alternating personalities,
formerly called multiple personality disorder.
Lois Bernstein/ Gamma Liason
Chris Sizemore (DID)
39
DID Critics
Critics argue that the diagnosis of DID
increased in the late 20th century. DID has
not been found in other countries.
Critics’ Arguments
1. Role-playing by people open to a
therapist’s suggestion.
2. Learned response that reinforces
reductions in anxiety.
40
Mood Disorders
Emotional extremes of mood disorders come in
two principal forms.
1. Major depressive disorder
2. Bipolar disorder
41
Major Depressive Disorder
Depression is the “common cold” of
psychological disorders. In a year, 5.8% of men
and 9.5% of women report depression
worldwide (WHO, 2002).

42
Major Depressive Disorder
Major depressive disorder occurs when signs of
depression last two weeks or more and are not
caused by drugs or medical conditions.

2.
3.
4.
Signs include:
Lethargy and fatigue
Feelings of worthlessness
Loss of interest in family & friends
Loss of interest in activities
43
Bipolar Disorder
Formerly called manic-depressive disorder. An
alternation between depression and mania
signals bipolar disorder.
Depressive Symptoms
Manic Symptoms
Gloomy
Elation
Withdrawn
Euphoria
Inability to make decisions
Tired
Slowness of thought
Desire for action
Hyperactive

44
Bipolar Disorder
Many great writers, poets, and composers
suffered from bipolar disorder. During their
manic phase creativity surged, but not during
their depressed phase.

45
Explaining Mood Disorders
Since depression is so prevalent worldwide,
investigators want to develop a theory of
depression that will suggest ways to treat it.
Lewinsohn et al., (1985, 1998) note that a theory
of depression should explain the following:
1. Behavioral and cognitive changes
2. Common causes of depression
46
Theory of Depression
3. Gender differences
47
Theory of Depression
4. Depressive episodes self-terminate.
5. Stressful events often precede depression.
6. Depression is increasing, especially in the
teens.

Suicide
The most severe form of behavioral response to
depression is suicide. Each year some 1 million
people commit suicide worldwide.

Biological Perspective
Genetic Influences: Mood disorders run in
families. The rate of depression is higher in
identical (50%) than fraternal twins (20%).

51
Social-Cognitive Perspective
The social-cognitive perspective suggests that
depression arises partly from self-defeating
beliefs and negative explanatory styles.
52
Negative Thoughts and Moods
Explanatory style plays a major role in becoming depressed.
53
Depression Cycle
1. Negative stressful events.
2. Pessimistic explanatory
style.
3. Hopeless depressed state.
4. These hamper the way the
individual thinks and acts,
fueling personal rejection.
54
Schizophrenia
The literal translation is “split mind” which
refers to a split from reality. A group of severe
disorders characterized by the following:
1. Disorganized and delusional
thinking.
2. Disturbed perceptions.
3. Inappropriate emotions and
actions.
55
Symptoms of Schizophrenia
Positive symptoms: the presence of inappropriate
behaviors (hallucinations, disorganized or
delusional talking)
Negative symptoms: the absence of appropriate
behaviors (expressionless faces, rigid bodies)
56
Disorganized & Delusional Thinking
This morning when I was at Hillside [Hospital], I was
making a movie. I was surrounded by movie stars …
I’m Mary Poppins. Is this room painted blue to get me
upset? My grandmother died four weeks after my
eighteenth birthday.”
(Sheehan, 1982)

(“I’m Mary
Poppins”).
57
Disorganized & Delusional Thinking
Many psychologists believe disorganized
thoughts occur because of selective attention
failure (fragmented and bizarre thoughts).
58
Disturbed Perceptions
A schizophrenic person may perceive things
that are not there (hallucinations). Frequently
such hallucinations are auditory and lesser
visual, somatosensory, olfactory, or gustatory.

59
Inappropriate Emotions & Actions
A schizophrenic person may laugh at the news
of someone dying or show no emotion at all
(flat affect).
Patients with schizophrenia may continually
rub an arm, rock a chair, or remain motionless
for hours (catatonia).
60
Onset and Development of
Schizophrenia
Nearly 1 in a 100 suffer from schizophrenia, and
throughout the world over 24 million people
suffer from this disease (WHO, 2002).
Schizophrenia strikes young people as they
mature into adults. It affects men and women
equally, but men suffer from it more severely
than women.
61
Chronic and Acute Schizophrenia
When schizophrenia is slow to develop
(chronic/process) recovery is doubtful. Such
schizophrenics usually display negative
symptoms.
When schizophrenia rapidly develops
(acute/reactive) recovery is better. Such
schizophrenics usually show positive
symptoms.
62
Understanding Schizophrenia
Schizophrenia is a disease of the brain exhibited
by the symptoms of the mind.
Brain Abnormalities
Dopamine Overactivity: Researchers found that
schizophrenic patients express higher levels of
dopamine D4 receptors in the brain.
63
Abnormal Brain Activity
Brain scans show abnormal activity in the
frontal cortex, thalamus, and amygdala of
schizophrenic patients.
Paul Thompson and Arthur W. Toga, UCLA Laboratory of Neuro
Imaging and Judith L. Rapport, National Institute of Mental Health
64
Abnormal Brain Morphology
Schizophrenia patients may exhibit
morphological changes in the brain like
enlargement of fluid-filled ventricles.

65
Viral Infection
Schizophrenia has also been observed in
individuals who contracted a viral infection
(flu) during the middle of their fetal
development.
66
Genetic Factors
The likelihood of an individual suffering from
schizophrenia is 50% if their identical twin has
the disease (Gottesman, 2001).

schizophrenia in identical twins as seen in
different countries.
68
Psychological Factors
Psychological and environmental factors can
trigger schizophrenia if the individual is
genetically predisposed (Nicol & Gottesman,
1983).

Genain Sisters
The genetically identical
Genain
sisters suffer from
schizophrenia. Two more than
others, thus there are

factors.
69
Personality Disorders
Personality disorders
are characterized by
inflexible and
enduring behavior
patterns that impair
social functioning.
They are usually
without anxiety,
depression, or
delusions.
70
Antisocial Personality Disorder
A disorder in which the person (usually men)
exhibits a lack of conscience for wrongdoing, even
toward friends and family members. Formerly,
this person was called a sociopath or psychopath.
71
Understanding Antisocial
Personality Disorder
Like mood disorders
and schizophrenia,
antisocial personality
disorder has biological
and psychological
reasons. Youngsters,
before committing a
crime, respond with
lower levels of stress
hormones than others
do at their age.
72
Understanding Antisocial
Personality Disorder
PET scans of 41 murderers revealed reduced
activity in the frontal lobes. In a follow-up study,
repeat offenders had 11% less frontal lobe activity

History of Insane Treatment
Maltreatment of the insane throughout the ages
was the result of irrational views. Many patients
were subjected to strange, debilitating, and
downright dangerous treatments.

History of Insane Treatment
Philippe Pinel in France and Dorthea Dix in
America founded humane movements to care
for the mentally sick.

81
Therapies
Psychotherapy involves an emotionally
charged, confiding interaction between a
trained therapist and a mental patient.
Biomedical therapy uses drugs or other
procedures that act on the patient’s nervous
system, treating his or her psychological
disorders.
An eclectic approach uses various forms of
healing techniques depending upon the client’s
unique problems.
82
Psychological Therapies
We will look at four major forms of
psychotherapies based on different theories of
human nature:
1.
2.
3.
4.
Psychoanalytic theory
Humanistic theory
Behavioral theory
Cognitive theory
83
Psychoanalysis
The first formal psychotherapy to emerge was
psychoanalysis, developed by Sigmund Freud.
Edmund Engleman
Sigmund Freud's famous couch
84
Psychoanalysis: Aims
Since psychological problems originate from
childhood repressed impulses and conflicts, the
aim of psychoanalysis is to bring repressed
feelings into conscious awareness where the
patient can deal with them.
When energy devoted to id-ego-superego
conflicts is released, the patient’s anxiety
lessens.
85
Psychoanalysis: Methods
Dissatisfied with hypnosis, Freud developed
the method of free association to unravel the
unconscious mind and its conflicts.
The patient lies on a couch and speaks about
whatever comes to his or her mind.
http://www.english.upenn.edu
86
Psychoanalysis: Methods
During free association, the patient edits his
thoughts, resisting his or her feelings to express
emotions. Such resistance becomes important in
the analysis of conflict-driven anxiety.
Eventually the patient opens up and reveals his
or her innermost private thoughts, developing
positive or negative feelings (transference)
towards the therapist.
87
Psychoanalysis: Criticisms
1. Psychoanalysis is hard to refute because it
cannot be proven or disproven.
2. Psychoanalysis takes a long time and is very
expensive.
88
Psychodynamic Therapy
Influenced by Freud, in a face-to-face setting,
psychodynamic therapists understand
symptoms and themes across important
relationships in a patient’s life.
89
Psychodynamic Therapies
Interpersonal psychotherapy, a variation of
psychodynamic therapy, is effective in treating
depression. It focuses on symptom relief here
and now, not an overall personality change.
90
Humanistic Therapies
Humanistic therapists aim to boost selffulfillment by helping people grow in selfawareness and self-acceptance.
91
Client-Centered Therapy
Developed by Carl Rogers, client-centered
therapy is a form of humanistic therapy.
The therapist listens to the needs of the patient
in an accepting and non-judgmental way,
addressing problems in a productive way and
building his or her self-esteem.
92
Humanistic Therapy
The therapist engages in active listening and
echoes, restates, and clarifies the patient’s
thinking, acknowledging expressed feelings.
Michael Rougier/ Life Magazine © Time Warner, Inc.
93
Behavior Therapy
Therapy that applies learning principles to the
elimination of unwanted behaviors.
To treat phobias or sexual disorders, behavior
therapists do not delve deeply below the
surface looking for inner causes.
94
Classical Conditioning Techniques
Counterconditioning is a procedure that
conditions new responses to stimuli that trigger
unwanted behaviors.
It is based on classical conditioning and
includes exposure therapy and aversive
conditioning.
95
Exposure Therapy
The Far Side © 1986 FARWORKS. Reprinted with Permission. All Rights Reserved.
Expose patients to
things they fear and
avoid. Through
repeated exposures,
anxiety lessens
because they habituate
to the things feared.
96
Exposure Therapy
Exposure therapy involves exposing people to
fear-driving objects in real or virtual
environments.
Both Photos: Bob Mahoney/ The Image Works
N. Rown/ The Image Works
97
Systematic Desensitization
A type of exposure therapy that associates a
pleasant, relaxed state with gradually increasing
anxiety-triggering stimuli commonly used to
treat phobias.
98
Aversive Conditioning
A type of
counterconditioning
that associates an
unpleasant state with
an unwanted behavior.
With this technique,
temporary
conditioned aversion
to alcohol has been
reported.
99
Operant Conditioning
Operant conditioning procedures enable
therapists to use behavior modification, in
which desired behaviors are rewarded and
undesired behaviors are either unrewarded or
punished.
A number of withdrawn, uncommunicative
3-year-old autistic children have been
successfully trained by giving and withdrawing
reinforcements for desired and undesired
behaviors.
100
Token Economy
In institutional settings, therapists may create a
token economy in which patients exchange a
token of some sort, earned for exhibiting the
desired behavior, for various privileges or
treats.
101
Cognitive Therapy
Teaches people adaptive ways of thinking and
acting based on the assumption that thoughts
intervene between events and our emotional
reactions.
102
Beck’s Therapy for Depression
Aaron Beck (1979) suggests that depressed
patients believe that they can never be happy
(thinking) and thus associate minor failings (e.g.
failing a test [event]) in life as major causes for
their depression.
Beck believes that cognitions such as “I can never
be happy” need to change in order for depressed
patients to recover. This change is brought about
by gently questioning patients.
103
Stress Inoculation Training
Meichenbaum (1977, 1985) trained people to
restructure their thinking in stressful situations.
“Relax, the exam may be hard, but it will be
hard for everyone else too. I studied harder
than most people. Besides, I don’t need a perfect
score to get a good grade.”
104
Cognitive-Behavior Therapy
Cognitive therapists often combine the reversal
of self-defeated thinking with efforts to modify
behavior.
Cognitive-behavior therapy aims to alter the
way people act (behavior therapy) and alter the
way they think (cognitive therapy).
105
Group & Family Therapies
Group therapy normally consists of 6-9 people
attending a 90-minute session that can help
more people and costs less. Clients benefit from
knowing others have similar problems.
© Mary Kate Denny/ PhotoEdit, Inc.
106
Family Therapy
Family therapy treats the family as a system.
Therapy guides family members toward
positive relationships and improved
communication.
107
Evaluating Therapies
Who do people turn to for help with
psychological difficulties?
108
Is Psychotherapy Effective?
It is difficult to gauge the effectiveness of
psychotherapy because there are different levels
upon which its effectiveness can be measured.
1.
2.
3.
Does the patient sense improvement?
Does the therapist feel the patient has improved?
How do friends and family feel about the
patient’s improvement?
109
Client’s Perceptions
If you ask clients about their experiences of
getting into therapy, they often overestimate its
effectiveness. Critics however remain skeptical.
1.
2.
3.
Clients enter therapy in crisis, but crisis may
subside over the natural course of time
(regression to normalcy).
Clients may need to believe the therapy was
worth the effort.
Clients generally speak kindly of their therapists.
110
Clinician’s Perceptions
Like clients, clinicians believe in therapy’s
success. They believe the client is better off after
therapy than if the client had not taken part in
therapy.
1.
2.
3.
Clinicians are aware of failures, but they believe
failures are the problem of other therapists.
If a client seeks another clinician, the former
therapist is more likely to argue that the client has
developed another psychological problem.
Clinicians are likely to testify to the efficacy of
their therapy regardless of the outcome of
treatment.
111
Outcome Research
How can we objectively measure the
effectiveness of psychotherapy?
Meta-analysis of a number of studies suggests
that thousands of patients benefit more from
therapy than those who did not go to therapy.
112
Outcome Research
Research shows that treated patients were 80%
better than untreated ones.
113
The Relative Effectiveness of
Different Therapies
Which psychotherapy would be most effective
for treating a particular problem?
Disorder
Therapy
Depression
Behavior, Cognition, Interpersonal
Anxiety
Cognition, Exposure, Stress Inoculation
Bulimia
Cognitive-behavior
Phobia
Behavior
Bed Wetting
Behavior Modification
114
Evaluating Alternative Therapies
57% of those who have had anxiety attacks and
54% who have had depression have used
alternative treatments such as herbal medicines,
massage, and spiritual healing (Kessler &
others, 2001). Do alternative therapies hold up
under scientific scrutiny?
115
Eye Movement Desensitization and
Reprocessing (EMDR)
In EMDR therapy, the therapist attempts to
unlock and reprocess previous frozen traumatic
memories by waving a finger in front of the
eyes of the client.
EMDR has not held up under scientific testing.
116
Light Exposure Therapy

Seasonal Affective
Disorder (SAD), a
form of depression,
has been effectively
treated by light
exposure therapy. This
form of therapy has
been scientifically
validated.
117
Commonalities Among
Psychotherapies
Three commonalities shared by all forms of
psychotherapies are the following:
© Mary Kate Denny/ PhotoEdit, Inc.
1. A hope for
demoralized people.
2. A new perspective.
3. An empathic, trusting
and caring
relationship.
118
Culture and Values in Psychotherapy
Psychotherapists may differ from each other
and from clients in their personal beliefs,
values, and cultural backgrounds.
A therapist search should include visiting two
or more therapists to judge which one makes
the client feel more comfortable.
119
Therapists & Their Training
Clinical psychologists: They have PhDs mostly.
They are experts in research, assessment, and
therapy, all of which is verified through a
supervised internship.
Clinical or Psychiatric Social Worker: They have
a Masters of Social Work. Postgraduate
supervision prepares some social workers to
offer psychotherapy, mostly to people with
everyday personal and family problems.
120
Therapists & Their Training
Counselors: Pastoral counselors or abuse
counselors work with problems arising from
family relations, spouse and child abusers and
their victims, and substance abusers.
Psychiatrists: They are physicians who
specialize in the treatment of psychological
disorders. Not all psychiatrists have extensive
training in psychotherapy, but as MDs they can
prescribe medications.
121
The Biomedical Therapies
These include physical, medicinal, and other
forms of biological therapies.
1. Drug Therapies
2. Brain Stimulation
3. Psychosurgery
122
Drug Therapies
Psychopharmacology is the study of drug effects
on mind and behavior.
With the advent of drugs, hospitalization in mental
123
institutions has rapidly declined.
Drug Therapies
However, many patients are left homeless on the
streets due to their ill-preparedness to cope
independently outside in society.

Double-Blind Procedures
To test the effectiveness of a drug, patients are
tested with the drug and a placebo. Two groups of
patients and medical health professionals are
unaware of who is taking the drug and who is
taking the placebo.

Antipsychotic Drugs
Classical antipsychotics [chlorpromazine
(Thorazine)]: Remove a number of positive
symptoms associated with schizophrenia such
as agitation, delusions, and hallucinations.
Atypical antipsychotics [clozapine (Clozaril)]:
Remove negative symptoms associated with
schizophrenia such as apathy, jumbled thoughts,
concentration difficulties, and difficulties in
interacting with others.
126
Atypical Antipsychotic
Clozapine (Clozaril) blocks receptors for
dopamine and serotonin to remove the negative
symptoms of schizophrenia.
127
Antianxiety Drugs
Antianxiety drugs (Xanax and Ativan) depress the
central nervous system and reduce anxiety and tension
by elevating the levels of the Gamma-aminobutyric acid
(GABA) neurotransmitter.
128
Antidepressant Drugs
Antidepressant drugs like Prozac, Zoloft, and Paxil are
Selective Serotonin Reuptake Inhibitors (SSRIs) that
improve the mood by elevating levels of serotonin by
inhibiting reuptake.
129
Mood-Stabilizing Medications
Lithium Carbonate, a common salt, has been used
to stabilize manic episodes in bipolar disorders. It
moderates the levels of norepinephrine and
glutamate neurotransmitters.

Brain Stimulation
Electroconvulsive Therapy
(ECT)
ECT is used for severely
depressed patients who do
not respond to drugs. The
patient is anesthetized and
given a muscle relaxant.
Patients usually get a 100
volt shock that relieves
them of depression.
131
Alternatives to ECT
Repetitive Transcranial
Magnetic Stimulation
(rTMS)
In rTMS, a pulsating
magnetic coil is placed
over prefrontal regions
of the brain to treat
depression with
minimal side effects.

Psychosurgery was
popular even in
Neolithic times.
Although used sparingly
today, about
200 such operations do
take place in the US
alone.

Psychosurgery
Psychosurgery is used as a last resort in
alleviating psychological disturbances.
Psychosurgery is irreversible. Removal of brain
tissue changes the mind.

Preventing Psychological Disorders
“It is better to prevent than cure.”
Peruvian Folk Wisdom
Preventing psychological disorders means
removing the factors that affect society. Those
factors may be poverty, meaningless work,
constant criticism, unemployment, racism, and
sexism.

Psychological Disorders are
Biopsychosocial in Nature
