exam 4 Flashcards
Defining “abnormal”
Cognitive model- abnormal thoughts or beliefs
Sociocultural model- violations of local social norms
Biological model-changes in biological functioning
Abnormality is inextricably attached to cultural norms, expectations, and laws
Thomas Szasz
The Myth of Mental Illness
-argued that the mental disorder classification system is an attempt by society to control those who are different, criticized the system of involuntary commitment
-criticized medical model as turning people into passive patients instead of active controllers of their own lives
-preferred the term “problems in living”
Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
the standard reference manual for disorder diagnosis and classification
Advantages:
-can be useful when properly used for diagnosis and treatment of disorders
-provides systematic structure for future research and insurance reimbursement
Criticisms:
-number of disorders INCREASED with each new addition
-providing classifications may lead to OVERDIAGNOSIS (ADHD, MPD/DID), PD-NOS is most commonly diagnosed disorder-despite there being 400 defined disorders, particularly a concern with newer DIMENSIONAL approach and RISK SYNDROMES
-gives the illusion of OBJECTIVITY
still subject to individual judgement, cultural norms( homosexuality), circumvention (NOS diagnosis)
Phobias
an exaggerated, unrealistic fear of a specific situation, activity, or object
agoraphobia
a set of phobias, often set off by a panic attack involving the basic fear of being away from a safe place of person
Post Traumatic Stress Disorder
when a person who has experienced traumatic events has symptoms such as numbing, reliving or trauma, detachment, relationship challenges, self-destructive behaviors
-military service-sexual abuse-9/11-1st responders
Obsessive Compulsive Disorder
person feels trapped in repetitive, persistent thoughts (obsessions) and repetitive, ritualized behaviors (compulsions) designed to reduce anxiety
-person understands that the ritual behavior is senseless but guilt and anxiety increase if not performed- cleanliness v contamination
Biological theory of depression
genetics and brain chemistry
Social theory of depression
the stressful circumstances of people’s lives
Attachment theory of depression
problems with close relationships
Cognitive theory of depression
negative/maladaptive habits of thinking or interpreting events (learned helplessness)
Bipolar disorder
a mood disorder in which a person alternates between episodes of depression and mania (excessive euphoria)
-driven primarily by brain chemistry
Narcissistic
a personality disorder characterized by an exaggerated sense of self-importance and self-absorption
Paranoid
a personality disorder characterized by habitually unreasonable and excessive suspiciousness and jealousy
Borderline
intense but unstable relationships, fear of abandonment, unrealistic self-image, emotional volatility, self-destructive behavior
Antisocial
a personality disorder characterized by antisocial behavior such as lying, stealing, manipulating others, and sometimes violence; and a lack of guilt, shame, and empathy
Schizophrenia
group of psychotic disorders marked by positive and negative symptoms that indicate a distorted perceptive of reality
Positive symptoms of Schizophrenia
something abnormal is present
-delusions, hallucinations, incoherent speech, inappropriate behavior
Negative symptoms of Schizophrenia
something normal is absent
-lack of affect, loss of motivation, social withdrawal
- may be grouped to form an overall state of catatonia- lack of movement, communication or excessive activity and confusion
Delusions
false beliefs that often accompany schizophrenia and other psychotic disorders
Hallucinations
sensory experiences that occur in the absence of actual stimulation
Diathesis-stress model
-environmental stressors can trigger physical vulnerabilities
-vulnerability may be genetic
*strong correlations in twin studies
-vulnerability may be brain abnormality
*research suggests prenatal neural differences
*synaptic pruning in adolescence may trigger early episodes
-vulnerability in neurotransmitter levels
*dopamine, glutamate
dopamine
can affect movement and emotion
glutamate
major excitatory neurotransmitter
Biological treatments
involve the use of drugs, electroconvulsive therapy (ECT), brain surgery or other methods that affect body or brain chemistry
CONCERNS
-some effects overstated due to publication bias
-placebo effect
-increasing off label prescription
*side effect are possibly worse than disorder symptoms
Off label prescriptions
bad with lithium and antipsychotics, leading to high relapses and dropout rates
long term effects
-addiction-diabetes- tardive dyskinesia
tardive dyskinesia- disorder that results in involuntary repetitive body movements, which may include grimacing, sticking out the tongue or smacking the lips, which occurs following treatment with medication
frontal lobotamy
-destroys or separates parts of the frontal lobes
-stops strong emotional reactions, leads to flat affect- severely restricted or nonexistent expression of emotion
-also can interfere with other frontal lobe functions- planning, socially appropriate behavior
Antonio Moniz’s Electroconvulsive Therapy (ECT)
-used in cases of severe major depression
-ineffective for other conditions
-initiated by Ugo Cerletti in 1937
-produces retrograde amnesia for the procedure itself
-widely used today
-criticized as a tool more of control than treatment
Antipsychotic drugs
-block or reduce sensitivity or brain receptors that respond to dopamine
-some increase serotonin, a neurotransmitter that inhibits dopamine activity
-can relieve positive symptoms of schizophrenia but are ineffective or worsen negative symptoms
-side effects are weight gain, diabetes
-increasing prescribed off label
Monoamine oxidase inhibitors (Nardil, Parnate)
elevate norepinephrine/ serotonin in brain by blocking an enzyme that deactivates them
