Main DSM–5 Categories of Mental
DisordersNeurodevelopmental DisordersThese are conditions
that begin early in development and cause significant
impairments in functioning, such as intellectual disability
(formerly called “mental retardation”), autism spectrum
disorder, and attention-deficit/hyperactivity disorder.
Schizophrenia Spectrum and Other Psychotic DisordersThis is a
group of disorders characterized by major disturbances in
perception, thought, language, emotion, and behavior. Bipolar
and Related DisordersThese disorders include major
fluctuations in mood—from mania to depression—and also can
include psychotic experiences, which is why they are placed
between the psychotic and depressive disorders in DSM–5.
Depressive DisordersThese are conditions characterized by
extreme and persistent periods of depressed mood. Anxiety
DisordersThese are disorders characterized by excessive fear
and anxiety that are extreme enough to impair a person’s
functioning, such as panic disorder, generalized anxiety
disorder, and specific phobia. Obsessive-Compulsive and
Related DisordersThese are conditions characterized by the
presence of obsessive thinking followed by compulsive behavior
in response to that thinking. Trauma- and Stressor-Related
DisordersThese are disorders that develop in response to a
traumatic event, such as posttraumatic stress disorder.
Dissociative DisordersThese are conditions characterized by
4. disruptions or discontinuity in consciousness, memory, or
identity, such as dissociative identity disorder (formerly called
“multiple personality disorder”). Somatic Symptom and Related
DisordersThese are conditions in which a person experiences
bodily symptoms (e.g., pain, fatigue) associated with significant
distress or impairment. Feeding and Eating DisordersThese are
problems with eating that impair health or functioning, such as
anorexia nervosa and bulimia nervosa.
7
Main DSM–5 Categories of Mental DisordersElimination
DisordersThese involve inappropriate elimination of urine or
feces (e.g., bed-wetting). Sleep–Wake DisordersThese are
problems with the sleep–wake cycle, such as insomnia,
narcolepsy, and sleep apnea. Sexual DysfunctionsThese are
problems related to unsatisfactory sexual activity, such as
erectile disorder and premature ejaculation. Gender
DysphoriaThis is a single disorder characterized by
incongruence between a person’s experienced/expressed gender
and assigned gender. Disruptive, Impulse-Control, and Conduct
DisordersThese are conditions involving problems controlling
emotions and behaviors, such as conduct disorder, intermittent
explosive disorder, and kleptomania. Substance-Related and
Addictive DisordersThis collection of disorders involves
persistent use of substances or some other behavior (e.g.,
gambling) despite the fact that it leads to significant problems.
Neurocognitive DisordersThese are disorders of thinking caused
by conditions such as Alzheimer’s disease or traumatic brain
injury. Personality DisordersThese are enduring patterns of
thinking, feeling, and behaving that lead to significant life
problems. Paraphilic DisordersThese are conditions
characterized by inappropriate sexual activity, such as
5. pedophilic disorder. Other Mental DisordersThis is a residual
category for conditions that do not fit into one of the above
categories but are associated with significant distress or
impairment, such as an unspecified mental disorder due to a
medical condition. Medication-Induced Movement Disorders
and Other Adverse Effects of MedicationThese are problems
with physical movement (e.g., tremors, rigidity) that are caused
by medication.

What Are the Disadvantages/Advantages of Labeling?
Disadvantage: Stigmas are likely attached to labeling people
with psychological disorders.
Roughly 60% of sufferers do not seek treatment.
Education does not dispel the stigma.
May result in unnecessary incarceration
May lead to low self-esteem
Advantages: Peace of mind, treatment

Therapists: Who
Provides Treatment?
Psychiatrists
Clinical psychologists (Ph.D. and PSY.D.)
Psychological associates (M.A.)
Counselling psychologists
12. Agoraphobia: Specific phobia involving a fear of public places.
23
Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD): An anxiety disorder in
which repetitive, intrusive, thoughts (obsessions) and ritualistic
behaviors (compulsions) designed to fend off those thoughts
interfere significantly with an individual’s functioning
Classified separately from anxiety disorders because the
disorder is believed to have distinct cause via different neural
circuitry
Roughly 2% of the population suffers
Moderate heritability
24
Treatments for Anxiety Disorders
Depends on the specific anxiety.
Relief of symptoms (e.g., tension, nervousness).
Antianxiety Medications – Xanax (which is a benzodiazepine),
Buspar (not a benzo) + CBT
Anti-depressants + CBT
How anti-anxiety meds work: Relief of tension, nervousness.
13. 25
Posttraumatic Stress Disorder: Troubles after a Trauma
Posttraumatic stress disorder (PTSD): Disorder characterized by
chronic physiological arousal, recurrent unwanted thoughts or
images of the trauma, and avoidance of things that call the
traumatic event to mind.
Brain imaging techniques: Identified important neural
correlates: Heightened amygdala activity; decreased medial
prefrontal cortex activity; smaller hippocampus (preexisting
condition)
Treatment: Anti-depressants (Paxil, Zoloft, Prozac) + CBT.
