Psychological Disorders

a syndrome that causes significant disturbance in behavior, emotion, and cognition

What is clinically dysfunctional behavior or thought?

syndromes that are generally limited to specific societies or culture areas and are localized, folk, diagnostic categories that frame coherent meanings for certain repetitive, patterned, and troubling sets of experiences and observations

this person believed

• mental illness = metaphor for problems in living

• criticizes psychiatry and argues against the concept of mental illness

“pseudopatients” told mental institutions symptoms and were admitted and diagnosed with serious disorders

• No staff identified them as fake patients

= proved diagnoses unreliable and supported deinstitutionalization

shifting care from long-stay psychiatric hospitals to community-based mental health services

a theory to explain disorders

= unconscious conflicts with others or with societal expectations lead to disordered behavior

a theory to explain disorders

= dysfunctional behaviors are the result of classical/operant conditioning gone wrong

or

the result of observational learning: watching others get rewarded for dysfunctional behaviors

a theory to explain disorders

= psychological disorders are the result of

• hormone/neurotransmitter imbalances

• genetic abnormalities

• brain damage

a theory to explain disorders that includes:

• cognitive approach

• humanist approach

• family systems approach

• biological approach

a theory that’s part of the Biopsychosocial Model to explain disorders

= maladaptive thinking → dysfunctional behavior

• individuals interpret their experience incorrectly

a theory that’s part of the Biopsychosocial Model to explain disorders

= faulty/interrupted development process social/emotional immaturity → disfunction

→ So, the goal of a humanistic therapy = to promote social/emotional maturity and growth

a theory that’s part of the Biopsychosocial Model to explain disorders

= familial behaviors, thinking, expectations, environment of household → dysfunctional behavior

= an individual may have a genetic predisposition for stress (nature) but an environmental trigger (nurture) is also needed for the disorder to appear

both Genetic Predisposition + Environment = disorder

BUT ALSO

how high or low ability to cope with stress is another factor of how likely you are to develop it

= the simultaneous presence of 1+ disorders in an individual

= the study of causes, progression, symptoms, diagnosis, and treatment of disorders

the probability of one person having the trait if the other does depending on their relationship

= the total # of both new and old cases in a population

given as a %

= rate of NEW occurrences of a condition in a population

= a diagnosis handbook

+ provides common language of symptoms

+ establishes consistent reliability for diagnosis

- DOES NOT include treatment of any disorder

= therapists must not reveal info about their patients unless they believe patient is an immediate threat to self or others

Neurodevelopmental Disorder #1

= limits to a person’s ability to learn at an expected level and function

1. symptoms

• sit up, crawl, or walk later than other children

• learn to talk later, or have trouble speaking

• find it hard to remember things

• have trouble understanding social rules

• have trouble seeing the results of their actions

• have trouble solving problems

2. onset: during childhood or adolescence

   prevalence: Approximately 1 – 3 % of the global population has an intellectual disability

3. causes/explanations for the disorder

• Genetic conditions. Sometimes an intellectual disability is caused by abnormal genes inherited from parents, errors when genes combine, or other reasons. ...

• Complications during pregnancy. ...

• Problems during birth. ...

• Diseases or toxic exposure

4. prognosis

• require support for life.

• the more severe the cognitive disability/physical problems the person has, the shorter the life expectancy

= how well a person handles common demands in life and how independent they are compared to others of a similar age and background

Neurodevelopmental Disorder #2

= any one of a group of disorders characterized by difficulties with social communication and social interaction and restricted and repetitive patterns in behaviors, interests, and activities

1. symptoms

the symptoms of people with ASD will fall on a continuum, with some individuals showing mild symptoms and others having much more severe symptoms. This spectrum allows clinicians to account for the variations in symptoms and behaviors from person to person

• language development

(doesn't speak or has delayed speech

• social development

(responding inappropriately in conversations,

misreading nonverbal interactions,

having difficulty building friendships appropriate to their age)

• cognitive development

(doesn’t express emotions or seem to understand others’ emotions,

unusually sensitive to light, sound, or touch,

indifferent to pain or temperature)

• need for routines

2. onset and prevalence

• onset: preschool years

• prevalence: 2.3%

3. causes/explanations for the disorder

• genetics

4. prognosis

• no cure for autism spectrum disorder,

• intensive, early treatment can make a big difference

5. any differences by demographic group?

• boys 4 times more likely to be diagnosed than girls

• families who have one child with autism spectrum disorder have an increased risk of having another child with the disorder.

• children with certain medical conditions have a higher than normal risk of autism spectrum disorder or autism-like symptoms.

• babies born before 26 weeks of gestation may have a greater risk of autism spectrum disorder

Neurodevelopmental Disorder #3

= pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development

• Needs to move; feels restless

• Can't sit through meetings, meals, movies

• Extremely impatient

• Finishes people's sentences; draws rapid conclusions (Blurts out answers before questions have been completely asked)

• symptoms start before age 12

• 4.4% of US adults have ADHD

genes and environmental factors likely plays a role in the development of the condition

• ADHD does not fade at a specific age

• no cure for ADHD

Neurodevelopmental Disorder #4

= individuals have sudden, rapid, recurrent, non-rhythmic, stereotyped motor movements or vocalizations

these movements/vocalizations called “tics”

broad category of disorders which are defined by delayed or impaired speech, language, motor condition, and visuo-spatial skills

= a break from reality

between ages 16 and 30

0.32% of people worldwide

Men often get symptoms earlier than women

3. causes

genetics: mutations, odds of developing is x10 greater if parent/sibling has it

brain structure: changes in prefrontal (working memory) and medial (declarative memory) temporal lobe regions

brain chemistry: neurotransmitters imbalance: too much dopamine and serotonin.

viral infection: x2 risk

neural pruning: An over excessive pruning of in regions responsible for functions affected by schizophrenia, like planning and cognition

• Environmental/Diathesis-Stress model

genetic predisposition + environment STRESS → schizophrenia

4. prognosis

   • lifelong treatment

=  mental health condition marked by a consistent pattern of intense discomfort with close relationships and social interactions

unlike schizophrenia, _____ disorder does not include hallucinations and delusions

and people with _____ disorder usually can be made aware of the difference between their distorted ideas and reality

• Hallucinations

• Delusions

• Disorganized speech/behavior

• Flattened Affect = suppressed emotional/facial expression

• Reduced Speech

• Loss of interest in activities

= false beliefs that are not based in reality

ex. you think that you're being harmed or harassed

ex. you think another person is in love with you

= seeing or hearing things that don't exist

= a mental health condition marked by large shifts in mood from mania to depression

• onset average: 25 years old

2.8% of US adults

3. causes

heritable component

Stressful events might include grief over a death in the family, trauma, loss of a job, the birth of a child or moving into a new home

4. prognosis

• 50% of patients experience a second episode within two years of the first episode. Poor prognosis is associated with: Substance dependency

Bipolar disorder may worsen with age or over time if the condition is left untreated. As time goes on, a person may experience episodes that are more severe and more frequent than when symptoms first appeared

BP 1 = episodes of depression, hypomania, and mania

BP 2 = episodes of depression and hypomania (less severe than mania)

= a milder form of bipolar disorder involving many "mood swings," with hypomania and depressive symptoms that occur frequently. People with cyclothymia experience emotional ups and downs but with less severe symptoms than bipolar I or II disorder.

A depressive Disorder

= a common and serious medical illness that negatively affects how you feel, the way you think and how you act.

1. symptoms

• mood/emotional symptoms

• feelings of sadness

• a loss of interest in activities you once enjoyed

• Angry outbursts, irritability or frustration, even over small matters

• cognitive symptoms

  • Difficulty thinking, concentrating or making decisions

  • Thoughts of death or suicide

• behavioral symptoms

  • Increase in purposeless physical activity (e.g., inability to sit still, pacing, handwringing) or slowed movements or speech (these actions must be severe enough to be observable by others)

  • Changes in appetite — weight loss or gain unrelated to dieting

2. onset and prevalence

• onset: Depression can occur at any time, but on average, first appears during the late teens to mid-20s

• prevalence: one in six people (16.6%) will experience depression at some time in their life.

3. causes/explanations for the disorder

• Biological

  • There is a high degree of heritability (approximately 40%) when first-degree relatives (parents/children/siblings) have depression.

  • People with depression appear to have physical changes in their brains. The significance of these changes is still uncertain, but may eventually help pinpoint cause

  • Brain chemistry. Neurotransmitters are naturally occurring brain chemicals that likely play a role in depression. Recent research indicates that changes in the function and effect of these neurotransmitters and how they interact with neurocircuits involved in maintaining mood stability may play a significant role in depression and its treatment

  • Hormones. Changes in the body's balance of hormones may be involved in causing or triggering depression

• Learning/Environmental

  • Synthetic Chemicals From Foods. ...

  • Natural Disasters. ...

  • Trauma. ...

  • Substance Abuse. ...

  • Chronic Illness and Injuries. ...

  • Grief

• Cognitive

  • people's thoughts, inferences, attitudes, and interpretations, and the way in which they attend to and recall events, can increase their risk for the development and recurrence of depressive episodes

4. prognosis

• Depression is among the most treatable of mental disorders. Between 80% and 90% percent of people with depression eventually respond well to treatment. Almost all patients gain some relief from their symptoms

  • antidepressants might be prescribed to help modify one’s brain chemistry.

  • Psychotherapy, or “talk therapy,” is sometimes used alone for treatment of mild depression; for moderate to severe depression, psychotherapy is often used along with antidepressant medications.

5. any differences by demographic group?

• Women are more likely than men to experience depression. Some studies show that one-third of women will experience a major depressive episode in their lifetime.

A depressive Disorder

= consistent sadness accompanied by eating/sleep disturbance, low energy/self-esteem, and diminished concentration

How is it different from Major Depressive disorder?

• Persistent depressive disorder lasts longer but does not include suicidal thoughts/attempts, so it is considered less acute but longer-lasting

A depressive Disorder

= depression with a regular seasonal pattern

How is it different from Major Depressive disorder?

• noticeable change in an individual’s mood, generally involving depression in cold,dark winter months and a lack of symptoms in the warmer months

• reduced light exposure has an impact on serotonin during fall/winter, seems to be main cause of SAD

• may have other contributing factors bc countries with extreme seasonal patterns (i.e. Norway and Sweden) have low suicide rates/rank high on happiest countries of the world

A depressive Disorder

= chronic and severe irritability and temper tantrums in young children

Why was DMDD added to the DSM-5?

• to address concerns about the potential for the over-diagnosis and treatment of bipolar disorder in children

1. symptoms

• severe, recurrent (≥3 times/week) temper outbursts (verbally and/or behaviorally) that are grossly out of proportion in intensity or duration to the situation, and inconsistent with the developmental level

• the mood between temper outbursts is persistently irritable or angry most of the day, nearly every day, and observable by others

• “hyperarousal” symptoms (insomnia, agitation, distractibility, racing thoughts or flight of ideas, pressured speech, and intrusiveness)

2. onset and prevalence

• by history or observation, the age at onset is before 10 years

• the diagnosis should not be made for the first time before age 6 years or after 18 years

• affects between 2-5% of children in the US, mostly male

3. causes/explanations for the disorder

• A young person’s genetic history is the strongest determining factor that could cause the onset of DMDD. In fact, among children and adolescents who meet criteria for this illness, all typically have a family history of depression, anxiety disorders, or substance use disorders in their backgrounds. Additionally, an irritable personality, which is said to be heritable, is an example of another way that genes can influence the onset of this disorder.

4. prognosis

• no treatment/cure yet

• More research is needed to determine whether treatment with SSRIs and/or stimulants is effective and safe in treating DMDD/SMD

• Behavioral and other psychotherapeutic interventions also should be considered in treating DMDD/SMD, particularly given their impairment in many social domains

5. any differences by demographic group?

• increased risk if male

• affects mostly school-age children

• increased risk if family history of anxiety, depressive, or substance use disorders

Anxiety Disorder #1

= A phobia is an intense fear of—or aversion to—specific objects or situations. Although it can be realistic to be anxious in some circumstances, the fear people with phobias feel is out of proportion to the actual danger caused by the situation or object

• Specific animals, such as spiders, dogs, or snakes

• Receiving injections

• Blood

1. symptoms

• May have an irrational or excessive worry about encountering the feared object or situation

• Take active steps to avoid the feared object or situation

• Experience immediate intense anxiety upon encountering the feared object or situation

• Endure unavoidable objects and situations with intense anxiety

2. onset and prevalence

• Onset: can first appear in childhood, usually by age 10, but can occur later in life.

• prevalence: 12.5% of U.S. adults experience specific phobia at some time in their lives

3. causes/explanations for the disorder

• Your relatives. If someone in your family has a specific phobia or anxiety, you're more likely to develop it, too.

• Past incidents or traumas. Certain situations might have a lasting effect on how you feel about them. ...

• Learned responses from early life. ...

• Reactions and responses to panic or fear. ...

• Experiencing long-term stress. ...

4. prognosis

• When left untreated, phobias can be lifelong, however, studies show that phobias tend to spontaneously attenuate over time. With the appropriate behavioral techniques and medications, the prognosis is good

Anxiety Disorder #2

= general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed

Anxiety Disorder #3

= frequent and unexpected panic attacks.

2. onset and prevalence

• onset: ​​Symptoms often begin before age 25 but may occur in the mid-30s.

• prevalence: estimated 2.7% of U.S. adults had panic disorder in the past year

3. causes/explanations for the disorder

• often occurs when there is no family history

4. prognosis

• Prognosis can be guarded. The presence of panic disorder without other psychopathology is rare. Most people will have a recurrence of symptoms even after a symptom-free period. Compliance with treatment is a major issue and thus relapse of symptoms is common. Only about 60% of patients achieve remission within 6 months. Triggers for poor outcomes include a chronic illness, high interpersonal sensitivity, unmarried, low social class, and living alone. Besides premature adverse cardiac events, these patients are also at a risk for suicide.

5. any differences by demographic group?

• Panic disorder is twice as common in women as it is in men

4. prognosis

For a diagnosis to occur, the symptoms must be present on an ongoing basis for at least one month after the incident.

Treatment can include medication, psychotherapy, or both. Support from family and friends is also crucial for the patients recovery

5. any differences by demographic group?

-Women are more likely to develop PTSD than men

-Black and Hispanic veterans were shown to have more elevated rates of PTSD

- minority groups are often not able to get access to treatment and therefore have higher severity of the disorder

= a mental health problem that can occur in the first month after a traumatic event

1. symptoms

• The symptoms of ASD are like PTSD symptoms, but you must have them for longer than one month to have PTSD

2. onset and prevalence

• Overall, within one month of a trauma, survivors show rates of ASD ranging from 6% to 33%. Rates differ for different types of trauma.

• onset can be at any age

3. causes/explanations for the disorder

• Several factors can place you at higher risk for developing ASD after a trauma: having gone through other traumatic events, having had PTSD in the past, having had prior mental health problems, and tending to have symptoms, such as not knowing who or where you are, when confronted with trauma

4. prognosis

• If you have ASD, you are very likely to get PTSD. Research has found that over 80% of people with ASD have PTSD six months later. Not everyone with ASD will get PTSD, though.

• Also, those who do not get ASD can still develop PTSD later on. Studies indicate that a small number (4% to 13%) of survivors who do not get ASD in the first month after a trauma will get PTSD in later months or years.

• cognitive behavioral therapy (CBT) shown to have positive results

• onset is during childhood

• prevalence of DSM-5 PTSD and DTD together is approximately 40%

3. causes/explanations for the disorder

• interpersonal trauma (either direct or witnessed emotional, physical, or sexual abuse) usually involving a parent or caregiver (can alter a child’s worldview when a relationship that was supposed to be nurturing and protective is the opposite of that)

4. prognosis

• In the absence of formal diagnostic recognition, the majority of treatment research has been devoted to PTSD, which may not fully capture treatment needs or translate to a more complexly-symptomatic sample of DTD patients

5. any differences by demographic group?

(this is data from a specific experiment, because stats are hard to find for something that isn’t officially in the DSM-5 lol) Regarding a DSM-5 PTSD-adult diagnosis, the distribution among ethnic groups was: 18% Black, 82% Hispanic, 0% White, and 0% Asian. In terms of meeting for the proposed criteria for DTD, the distribution within ethnic groups was: 30% White, 23% Hispanic, 20% among Black, and 0% among Asian.

= when a person exhibits 2+ distinct personalities

due to conscious awareness separated from previous memories/thoughts

1. symptoms

• memory loss of certain time periods, events, people, and personal information

• depression, anxiety, suicidal thoughts or behavior

• blurred sense of identity

2. onset and prevalence

• The typical patient who is diagnosed with DID is a woman, about age 30. A patient’s history typically will reveal onset of dissociative symptoms at ages 5 to 10

• very rare

3. causes/explanations for the disorder

• it can be caused by severe and prolonged trauma experienced during childhood, including emotional, physical or sexual abuse.

4. prognosis

• The primary treatment for DID is psychotherapy. Also known as talk therapy or psychosocial therapy, psychotherapy is focused on talking with a mental health professional about your mental health.

= when a person blocks out specific info, no memory of a specific event

1. symptoms

• memory loss that's more severe than normal forgetfulness

• can't recall information about yourself or events and people in your life, especially from a traumatic time.

How is it different than retrograde amnesia?

retrograde amnesia is forgetting the events that occurred before a traumatic event, while _________ is forgetting the traumatic event

2. onset and prevalence

usually sudden

• rare. It affects about 1% of men and people assigned male at birth and 2.6% of women and people assigned female at birth in the general population

3. causes/explanations for the disorder

environment also plays a role. Rates of dissociative amnesia tend to increase after natural disasters and during war

4. prognosis

memory eventually returns, sometimes slowly and sometimes suddenly, which makes the overall outlook very good

5. any differences by demographic group?

more common among women than men, usually people who have experienced or witnessed traumatic events, such as physical or sexual abuse, rape, wars, genocide, accidents, natural disasters, or death of a loved one

a subtype of dissociative amnesia

= when someone temporarily has amnesia and ends up in a location not knowing how they got there with no awareness of their identity

= when a person has a significant focus on physical symptoms, such as pain, weakness or shortness of breath, to a level that results in major distress and/or problems functioning. The individual has excessive thoughts, feelings and behaviors relating to the physical symptoms. The physical symptoms may or may not be associated with a diagnosed medical condition, but the person is experiencing symptoms and believes they are sick (that is, not faking the illness).

= an unrealistic fear that they have a serious medical condition or fear that they're at high risk of becoming ill

= ​​condition in which a person experiences physical and sensory problems, such as paralysis, numbness, blindness, deafness or seizures, with no underlying neurologic pathology

Eating disorder

= related to starvation

1. symptoms

Physical

• Extreme weight loss or not making expected developmental weight gains

• Thin appearance

• Abnormal blood counts

• Fatigue

• Insomnia

• Dizziness or fainting

• Bluish discoloration of the fingers

• Hair that thins, breaks or falls out

Behavioral/Emotional

• Bingeing and self-induced vomiting to get rid of food

• Frequently skipping meals or refusing to eat

• Denial of hunger or making excuses for not eating

2. onset and prevalence

• between 12-25

• 6% of the total population,

  • but college-age women are estimated to suffer between 19% and 30%

3. causes/explanations for the disorder

• psychological

  • unrealistic perception of body weight and an extremely strong fear of gaining weight or becoming fat

  • may have obsessive-compulsive personality traits that make it easier to stick to strict diets and forgo food despite being hungry.

  • extreme drive for perfectionism, which causes them to think they're never thin enough.

  • high levels of anxiety

• Biologically

  • may be genetic changes that make some people at higher risk of developing anorexia. Some people may have a genetic tendency toward perfectionism, sensitivity and perseverance — all traits associated with anorexia

• Social/Environmental

  • Modern Western culture emphasizes thinness. Success and worth are often equated with being thin. Peer pressure may help fuel the desire to be thin, particularly among young girls.

4. prognosis

• may result in suffering nerve damage that affects the brain and other parts of the body. As a result, these nervous system conditions can include: Seizures. Disordered thinking

5. any differences by demographic group?

• three times higher among females (0.9%) than males (0.3%)

• Unlike anorexia, (ARFID) does not involve a fear of weight gain

Overall, ARFID means that a person severely avoids or restricts food. However, there are several different ways that ARFID can present, such as:

• Sensory sensitivity, where people avoid foods of certain types or textures, such as meat, fruits or vegetables

• Avoidance of certain foods or food altogether after choking or vomiting

• Restriction or avoidance of food due to low appetite or general disinterest in eating

=  a serious, potentially life-threatening eating disorder. People with bulimia may secretly binge — eating large amounts of food with a loss of control over the eating — and then purge, trying to get rid of the extra calories in an unhealthy way. (purging)

1. symptoms

• Being preoccupied with your body shape and weight

• Living in fear of gaining weight

• Repeated episodes of eating abnormally large amounts of food in one sitting

• Feeling a loss of control during bingeing — like you can't stop eating or can't control what you eat

• Forcing yourself to vomit or exercising too much to keep from gaining weight after bingeing

• Using laxatives, diuretics or enemas after eating when they're not needed

• Fasting, restricting calories or avoiding certain foods between binges

• Using dietary supplements or herbal products excessively for weight loss

• The severity of bulimia is determined by the number of times a week that you purge, usually at least once a week for at least three months.

• Negative self-esteem and problems with relationships and social functioning

• Dehydration, which can lead to major medical problems, such as kidney failure

• Heart problems, such as an irregular heartbeat or heart failure

• Severe tooth decay and gum disease

• Absent or irregular periods in females

• Digestive problems

• Anxiety, depression, personality disorders or bipolar disorder

• Misuse of alcohol or drugs

• Self-injury, suicidal thoughts or suicide

2. onset and prevalence

• Bulimia often begins in the late teens or early adulthood.
