Psychological Disorders

Psychological Disorders

n  Psychological behaviors run a continuum from very mild to extreme. Everyone has these behaviors to one degree or another. It is not until a behavior or feeling interferes with your quality of life that they become a disorder.

Psychological Order

n  Self-acceptance: understanding yourself and accepting the good and bad parts of yourself.

n  Positive relationships with others: ability to form good trusting interpersonal relationships.

n  Autonomy: self-controlled and able to resist peer pressure.

Psychological Order

n  Environmental masters: internal locus of control; master of your domain.

n  Purpose in life: goals and sense of direction; not diffused.

n  Personal Growth: see yourself growing and expanding; self knowledge; self actualization.

Psychological Disorders are:

n  Atypical, disturbing, maladaptive, and unjustifiable behavior.

Psychological Disorders: Causes

n  Are not usually caused by a single factor. The medical model is probably not correct where you can take a pill to rid yourself of a disorder.

n  The bio-psycho-social school most disorders are caused by a biological predisposition, physiological state, psychological dynamics, and social circumstances.

Defining Disorders

n  DSM IV-Diagnostic and statistical manual vol. 4.: attempts to describe psychological disorders, without explaining the causes, predicts the future course, and suggests treatments.

n  Categorizes 230 disorders, in 17 categories.

Dangers of labeling

n  Labeling someone with a disorder can create self-fulfilling prophesies, where the label creates the behavior. Also, if a professional hears a persons “has” a disorder, they may look back at that person’s history and see things that “caused” those behaviors, which might not be accurate.

Anxiety Disorders

n  General anxiety disorder: Persistent symptoms of an excited sympathetic, nervous system: sweating, heart racing, dizziness, shaky accompanied by persistent negative feelings and fear…not triggered by specific events.

Anxiety Disorders

n  Panic disorder: unpredictable, minutes long intense anxiety attack, as if you're going to be killed any second, but no specific, real threat is apparent.

n  Behavioral: learned fear, which has been reinforced, or social learning, imitating others who has fear like parents. May be generalized from other learned experiences: one dog to all dogs.

n  Biological: predisposed genetically to be afraid of things that can cause death: snakes, spiders, height, enclosed places, disease.

Post Traumatic Stress disorder

n  Caused by prolonged or intensely stressful situations, like war or rape. Symptoms: difficulty sleeping, nightmares; anxiety attacks or GAD; intrusive memories; Guilt associated with event;

n  Some psychologists dismiss this disorder pointing to those who do not get it after experiencing similar trauma. That probably has more to do with biological predisposition than to lack of evidence that PTSD existence.

Major depressive disorder

Treatments for depression

n  Cognitive therapy is effective, with antidepressants: trying to change internal sentences. Because depressed people see the world through dark glasses, their thoughts intensify the feelings leading to a downward spiral.

n  Medical: now treated with classes of serotonin reuptake inhibitors. SSRIs. They keep serotonin in the synapse longer, elevating mood.

Treatment for Dythmic depression

n  College students with dysthmic or moderate depression responded far better to aerobics than other treatments.

Cognitive Style

Bipolar disorder (manic-depression):

n  Bipolar disorder (manic-depression): alternates between hopelessness and lethargy of depression and over-excited manic state.

Bipolar disorder (manic-depression):

n  Manic state: typically over-talkative; overactive; little or no sleep; highly impulsive, loud, flighty, hard to interrupt sexually less-inhibited. Grandiose optimism and self-esteem. May be very irritable.

n  People then fall back to either a normal state, or into a major depressed state

Treatment for Bipolar

n  Treatment: In manic state: high levels of neurotransmitter norepinephrine.

n  Treatment: usually with lithium for the manic state and antidepressants for the depression.

n  Treatment is very effective if patients continue using medication.

Depression Facts

n  Facts: Major Depression usually lasts less than three months; may or may not return; often triggered by stressful events, although not necessarily caused by it (biological predisposition);

n  Dysthimic depression lasts two years or longer.

n  Schizophrenia thinking may be seen as an uncontrolled rapid change of selective attention, where the mind rapidly shifts from one thought to another.

Causes

n  Psychology: triggering experiences, genes predispose but some react to traumatic triggers by developing schizophrenia. They vary.

n  Biochemical: 6 times the normal amount of dopamine receptors that increase brain activity to manic levels. Thus dopamine blockers reduce symptoms.

Causes

n  It is also thought to perhaps be triggered or caused by the introduction of a prenatal virus that affects brain development, possibly in the thalamus. People conceived in Winter months are more apt to develop schizophrenia in Northern hemisphere, while the reverse is true in the Southern.

Rule of Thirds

n  About 1/3 of people who develop schizophrenia only have one episode, 1/3 have reoccurring episodes, and 1/3 are chronic with unremitting symptoms.

Causes

n  Amphetamines and cocaine sometimes intensify symptoms. Dopamine is also associated with physical movement, disruption of is associated with schizophrenia.

n  Brain anatomy: they have abnormal brain tissue, low frontal lobe activity.

n  Thalamus react smaller than normal and is reactive that may cause brain over stimulization.

n  People exposed to certain flu viruses during prenatal development have higher incidences.

Genetic factors

n  Definite genetic link: the closer you are genetically to someone with Schizophrenia, the more likely you are to get it.

n  1 in 100 people get it.

n  1 in 10 of siblings

n  1 in 2 identical twins, even if raised apart
