PSY 303 MIDTERM CHAPTER 8 ANXIETY DISORDERS AND OBESSIVE COMPULSIVE DISORDER -anxiety disorder -generalized anxiety disorder GAD -social anxiety disorder SAD -panic attack -anxiety: is the fear of what might happen -fear and anxiety involve high-level as well as primitive brain processes -research suggest that anxiety should be seen as developmental problem involving both environmentl and genetic factors -limbic system processes respond to stimuli in their own. Cognitive Processes in Anxiety: • Evolution of fear mechanisms. • Cognitive bias. • Stroop test : sari renk gosterip yesil yazma testi , cognitive biasta kullaniliyor • Anxious individuals focus on negative Developmental Aspects of Anxiety • Factor increasing level of fear. • Influence on popularity and social competence. • Anxiety more prevalent among adolescents. # • Rates higher than mood disorders Models of Anxiety Development • Role of genetics, epigenetics. • Fear learnt from family and culture. Seperation Anxiety Disorder: - show distress when seperated from their caregivers -processes an children develop independence and the abiliy to function on their own -at least 4 weeks treatment: to recognize anxious feelings when they occur Generalized Anxiety Disorder: -anxiety leads to four behaviors: 1. avoiding activities that can have negative outcomes 2. overpreparation for activities that can have negative outcomes 3. marked procrastion behvaviors due to wworries 4. repeatedly seeking reassurance Treatment: cognitive behavioral approaches -mindfulness -medications such as benzodiazepines with psychotherapy Social Anxiety Disorder: concerned about meeting someone or about giving a talk in front of a group treatment: CBT, exposure therapy, social skills training Agoraphobia: in which person experinces fear or anxiety when in public - age onset: 21-23 - diagnose in relation to panik disorder - CBT approaches, antideprants effective Specific Phobia: in which an individual experinces fear or anxiety about a particular situation or object ( snakes,spiders..) Panic Disorder: intense feeling of apprenshion,fear or anxiety peak in first 10 min often seen comorbid with agoraphobia Obessive-Compulsive Disorder: - may be autogenous or reactive - obsessions are generally unwelcome thoughts that come into ones head - compulsive are the behaviors one uses to respond to these thoughts • • • • Hoarding disorder : excessive aquisition of objects and an initabbility to discard these objects Body dysmorphic disorder : preoccupation with a perceived flaw in ones physical apperace Trichotillomania. Excoriation or skin picking. Treatment for OCD • • • Most common medications : clomipramine ,trylic antideprseants Exposure and response prevention Prolonged exposure to feared thoughts. Deep brain stimulation. EATING DISORDERS CHAPTER 10 FEEDING DISORDER: PICA is a feeding disorder in which the person eats something that would not be considered food.( clay,cornstrach,characol,newspaper..) nonnuntrive substances eating behavior have leasted for longer than 1 Month it leads to health problems RUMINATION DISORDER -is when a person regurgitates his food (Yiyeceklerin yutulduktan sonra tekrar ağza getirilmesini ve yeniden yutulmasi) -the swallowed food is then rechewed or spit out -must occur more then 1 month and not any part of any medical or eating disorder -can result: halitosis ,, malnutrition,electrolyte,imbalance, dental problems AVOIDANT/RESTRIVTIVE FOOD INTAKE DISORDER -is when an individual does not eat certain foods, which leads to such conditions such as weight loss or nutritional deficieny -common in children 2-3 years , this Is referreed to as the Garcia effect or one trial learning THE PROBLEM OF OBESITY: Thrifty gene hypothesis: suggest that times of scares food sources helped shape our genetic makeup evolutionary history may have us seeking substances that do not lead to a healthy lifestyle ( for example sugar was not easy to come by ) environmental facts-> family,culture,towns psychological facts-> self-esteem, need for comfort biological facts ->genetic makeup a homeostatic system regulates the body weight brain processes involving the limbic system that encode the reardinf aspect of food intake along with emotional and cognitive aspect-> these brain processes lead to overconsumption of food even when the person feels full drug addiction and obesity involve discruption in the dopamine pathways of the brain brain processes involving the limbic system encoding the rewading aspect of food intake along with emotional and cognitice aspects. obesity , like drug addiction involves the distruptions in dopamine pathways these pathways modulate behavioral responses to environmental cues food and drug, psychological processes interact in a complex manner -> when we see food or drug we like there are memory (hippocampus) , emotional (amgydala), arousal ( thalamus), cognitive control (prefrontal cortex PFC) as well as autonomic nervous system reactions related to consuming intake food or drugs: cognitive system, a dopamine reward system, energy system Psychological stress increases our consumption of food and weight gain BRAIN MECHANIMS RELATED TO THESE SYSTEMS ARE CHANGEABLE EVEN IN ADULTHOOD -> as environmental conditions change,metabolic brain circuits change in relation to eating BMI: body fat based on a persons height and weight health problems: hypertension, dyslipidemia, diabetes,stroke,coronary heart diseases,sleep apnea, some cancers , DEPRESSION Differences in the View of Ideal Weight Between Males and Female THE MAJOR EATING DISORDERS ->anorexia nervosa, bulimia nervosa, binge eating disorder developmental pattern symtomps such as weight preoccupation, body dissatisfaction, disordered eating - partial genetic component -cultural component ANOREXIA NERVOSA two subtypes: the restricting type & binge eating or purging type -food refusal, onset in adolosence, lack of concern about the consequences of not eating charactericts: - -onset and consistency -distorting body image -lower than normal BMI Neuroscience: - brain imaging of three components: o the perception component: showed difrrences in the purcuneus and the interfior partieal lobe o the affective component: involved in PFC, the insula, the amgydala o the affective and cognitive component: involved in amgydala, parietal lobe, prefrontal lobe -Gut bacteria: are involved in the emotionalty and eating patterns of those with eating disorder. can influence in how medications affect you , may reduce the effect Causes: -Suggestive risk factors( familial,biological factors, psychological factors, behavior, cultural,stressful life events) -genetic -> twin studies suggest that both anorexia and bulimia can accounted by genetics. -reduction of brain metabolism -> frontal,cingulate,temporal,partieal areas -cultural factors: western culture Treating anorexia: -deny and not wanting to be treated -familiy therapy: family based therapy is refereed to Maudsley approach( 3 phases:1. weight restoration, 2.adolesecene take more control, 3.emphasizes developing healthy identity) -Cognitive behavioral therapy: help the person develop productive thoughts and feelings around his or her eating and view of self BULIMIA NERVOSA (1) binge eating in which person consumes large amounts of food (2) purging where a person eliminates food from the body by such vomiting ,taking laxatives, diuretics, enemas (3) a psychological aspect in which ones self worth is seen in relation to ones weight or bodyshape -periods of overeating , out of control -self induces vomiting or takes laxatives or medications to eliminate food , overexercise compared with anoriexia: Body Weight NORMAL -purging -can lead to medical problems(menstrual disturbance,dental erosion, ..) causes: -genetic, cultural factors, differences in anxiety,self-esteem,sexual abuse Treatment: -Cognitive behavioral Therapy , Antidepressant medications BINGE EATING DISORDER -consumption of large amounts of food without purging -higher in overweight individuals Treating: - -Cognitive behavioral therapy Goals of treatment , Psychosoical and other approaches, drug treatments(show limited evidence of success) DISSOCIATIVE DISORDER ch. 9 is a loss of the normal intergration of cognitive functioning. this includes the persons self, autobiographical memory, a sense of control and agency, intergrated awareness of functioning Pathological dissociative symtoms: normal integration of consiuness,memory, identity, perception Depersonalization -> is the perception of not experiencing the reality of one’s SELF Derealization -> is the experience that the world is not solid individuals with depersonalization disorder showed reduced autonomic responses to unpleaseant stimulu. Inhibitory responses to negative emotional info Dissociative Amnesia -> is an inability to recall important autobiographical info Dissociative Fugue -> unexpected travel away from ones home or place with an inability to recall ones past unable to remember their historical experience, procedural memory; is not lost nor is the ability to create ne long-term memeories Dissociative identity disorder DID multipe personality disorder, there is a large amount of misinformation concerning its existence current views it is less a disorder of multiple personalities experience different ‘personlaties’ at different times distruption in memory; (1) the person may not remember significant parts of his or her life (2) the person may not remember how to perform an act or well learned skill such as driving (3) the person may discover evidence of actions that he or she does not remember doing Neuroscience research related to DID compared with other disorders, the volume of the hippocampus and amgydala was studied with MRI , those with DID hat a smaller volume compared with healthy control group Treatment: - dissociative amenisa : solve on their own long term treatment /long term psychopatherapy no established medications SEXUAL DISORDERS, PARAPHILIC DISORDERS, GENDER DYSPHORIA ch 11 Sexuality; more then the sexual experience; a central being human encompasses sex, gender identities and rolea,sexual orientation,eroticism, pleasure,intimacy,reproduction Historical perspectives: -depiction in paintings and carvings -in some cultural seen as a negative force -charles darwin: the manner in which sexual selection and self preservation were important -Sigmund freud: emphasized the way in which sexuality was imoortant for driving force in humans - Alfred kinsey: survey focused on 6 outlets of sexual orgasm: masturbation, petting, nocturnal dreams, heterosexual coitus, homosexual behaviors, bestiality Sexual desire, arousal, response -desire for sex -distinct processes: psychsiological sense to refer to the internal experience of both cognitive and emotional processes measaurement : electrocephalogy EEG , functional magnetic resonance imaging fMRI Your brain and Sexual Activity - brain imaging studies-> cortical measures of arousal in addition to selfreport and blood flow changes in sexual organs - Ferettis study: the processing of sexual arousal engages coplex brain networks involving cognitive, emotional and self-processes eye tracking: measure when a person looks when viewing stimuli in real time Masters and Johnson: identified four phases of human sexual response: (1) excitement -> blood flow is increased in genital region, increased muslc tension (2) plateau -> pleasurable internal experience continue, increase in heart rate and breathing (3) orgasm-> muscular contractions in the male cause the sperm to be released (4) resolution -> return to pre-arousal, SEXUAL DYSFUNTION DISORDERS causes significant distress or impairment 3 perspectives -> medical and biological factors, psychological , relationship itself Erectile Disorder -> (1) cannot obtain an erection during sexual activity (2) cannot maintain an erection to completion of sexual activity (3) decrease in rigidity of penis in a way interferes with sexual activity Female Orgasmic Disorder -> the condition in which a woman either does not experience an orgasm Delayed Ejaculation -> the situation in which a male shows an unwanted delay of ejaculation Early Ejaculation-> an ejaculation approx. in the first min of sexual activity (premature ejaculation de traditionally called) Female Sexual Interest/Arousal Disorder -> reduction or absence of interest in sexual activity Male Hypoactive Sexual Desire Disorder -> male has little desire for sexual activity Genito-Pelvic Pain/Penetration Disorder -> pain, fear, anxiety during sexual activity dyspareunia: type of pain during intercourse Vaginismus: vagina is attemptet , the muscles of vagina pelvic flood spasm Treatment: Sex therapy, understanding psy factors, medicaitons ( Viagra, Levitra, Cialis ) PARAPHILIC DISORDERS paraphilia: nontraditional sexual activities paraphilia disorders: paraphilia causing distress para-> paranormal , philia-> refers to love or affection Exhibitiontisic Disorder is the case in which a person becomes sexualy arousal by exposing his genitals to an unsuspecting stranger often called a flasher , a male exhibitionst will find a place where women are expected to be Treatment: group therapy and SSRI Frotteuristic Disorder gains sexual arousal from touching or rubbing against nonconsenting persin only seen in men two conditions for diagnosis: (1) the experience of sexual arousal, have lasted at least 6 months (2) condition results in marked distress Fetishictis Disorder erotic fixtation on nonsexual object or body part Pedophilic Disorder persistent interest in children seen to develop in adolescence structural and functional brain diffeences no effective treatment Sexual Masochisim Disorder sexual arousal from being humiliated asphyxiation : the process in which a person puts a plastic bag over his head or rope around hic neck to cut off oxygen temprorily Sexual Sadisim Disorder sexual pleasure from inflicting pain or humiliation on others does not appear in isolation Trasnvenstic Disorder to dressing in clothing that is typically worn by the opposite sex Voyeuristic Disorder sexual arousal from watching unsuspecting people mainly seen in men before the age of 15 Other Paraphilic Disorders -specified paraphilic disorder: cause all symptoms but do not satisfy any criteria of the disorders , this can include sexual arousal from making obscene phone calls, corpses, anilmas ,feces, urines,enemas -unspecified parahilic disorder: insufficient info to make a more speciif diagnosis Causes and Treatment: - Androgen and future sexual behavior some type of learning 3 sources of treatment: the courts, a partner, the person himself Psychopharmacological treatments Gender Dysphoria Gender roles: one’s culture in terms of the kinds of activities boys and girls are expactedt to engage Gender Identity: internal experience of knowing that you are male or female Gender Dysphoria: may have born as one gender in terms of their body, but the internal experience is that of the other gender. Dysphoria is defined as a sense of unease or suffering Gender Dysphoria can be seen in children, adolescents, adults Diagnosis in Children: at least 6 months present , at least 6 of 8 criteria must be present Diagnosis in adolescents and adult: 6 months duration of significant distress , impairement in social , also 2 of 6 criteria must be present Transgender-> who have the anatomy of one sex and the gender identity of the other Transsexual -> transgender individual medical intervention such as hormone treatment and gender-affirming surgey to change the body The Brain and Gender Dysphoria Amsterdam cohort : brain activity and structure in transgender adolescents more closely resemebles typical activation patterns of their desire gender white matter fiber pathways: who experienced themselves as male did indeed look similar to those non-dysphoric individuals who were anatomically male Cortical Thickness Providing Assistance for Individuals with gender Dysphoria - psy interventions for children suicide ideation in adolescent and adults gender transition surgery gender reassignment procedure SUBSTANCE – RELATED & ADDICITIVE DISORDERS CH 12 Drug use in the United states - -change in attitude toard drug use - -changes in worldwide drug use - -prohibition and laws against drugs Substance Abuse, Dependence and Addiction disordered use-> causes impairment or distress intoxication -> effects of substance withdrawal -> symptoms experienced when the substance is no longer used 3 major components to dependence: (1) the desire to seek and take a certain substance (2) the inability to avoid or limit the intake of the substance (3) the experience of negative emotional states when the substances is not available Who becomes addicted? • -timing of use ( 15 yasdan once baslayinca daha olasik) • drugs affect adolescents in a different manner than they do adults • drugs have direct influence on the frontal lobe Genetic , environment , evolutionary influences • -genetic factors • environmental factors such as stress and low socioeconomic levels, epigenetics • social well-being Pattern of Addiction (1) intoxication (2) bingering (3) withdrawal (4) craving -> losing control to limit intake -increased tolerance -emergence of negative emotional state -rewarding effect of drugs is based on their ability to increase dopamine , the mesomblic dopamine system Can Drugs change your brain? - YES - Pathways connect with the nucleus accumens prefrontal cortrxx, dorsal striatum, amgydala - dopamine is releseade in these structures -> reward or pleasure - molecular mechanisims of many drugs leave excessice dipamine availbe in the brain - cocaine BLOCKS dopamine uptake in the synpase or increases dopamine - Nictone,alcohol,stimulants, marijhana all increase dopamine in the dorsal stratum abd ventral s - disruption of prefrontal cortex -Drug addiction can be seen as a form of enhanced motivation ALCOHOL alcohol use -> intoxication and withdrawal -alchol decreases inhibition -can lead to social,legal,medical problems Effects of alcohol on the human body directly into bloodstream broken down into carbon dioxide, water genetic component in dependence dependence runs in families Moderate , Heavy, Binge Drinking Binge Drinking: consuming enough alcohol in a period Do people who drink more like it more? -relationshio between wanting & liking MARIJUHANA, HALLUCINGENS, OPIOIDS Canabis -wide variety of experiences -enjoayble feelings, influence appetite -the brain produces substances that are similar: cannabinioids larger doses produce hallucinations Hallucinogenes somatic, perceptual, psychic symptoms also called psychedelics alter perception and cognitive experiences altered states of consciuousness scale do not producw dependence brain blood research -> increases frontal area of the brain , the insula, anterior and posterior cingulate using hallucinogens in clinical treatment LSD, mescaline, psilocybin chemical makeup similar to serotonin Opioids affect the brain and spinal cord by influencing neurotarsbanitter at the level synapse psychoactive substance opioids used in medical settings heroin, opium, morphine , methadone, oxycodone receptors in our brain that are sensitive to opioid drug STIMULANTS: COCAINE, AMPHETAMINE, CAFFEINE, NICTOINE Cocaine mental alterness, combined with euphoria, energy and desire to talk shorter effect compared to other drugs increased heart rate and blood pressure the smoked form: crack reuptake : dopamine is than removed from the receptors long lasting brain changes Amphetamine positive feelings , a burst of energy, alertness produced in the lab euphoria, incereaed alertness, hyperactivity cog deficits from metgamphetamine Caffeine works through nervous system increases serotonin brain stem added to energy drinks, weight loss drugs caffeine intoxication: clinically significant distress/impairement caffeine withdrawal Tobacco -> Nicotine addictive substance is nicotine functions stimulant,depressant Gambling pathological gambling: addictive disorder comorbidity : mental disoders substance tolerance role of cog-emotional processes (1) behavioral conditioning,(2) cog-emotional process (3) impulsivity (4) impaired executive Treatment of Substance-Related Disorders -psychsocial approaches -> cognitive behavioral therapy -first steo to remove drug from system - motivational interviewing: that seeks to use the clients motivation to produce change effective treatrment : 13 princeples The 12 step program: forms basis for AA Controlled drinking approaches : learning to use alcohol Medications -> (1) agonist (2) antagonist (3) aversive PERSONALITY DISORDERS CH 14 (1) represents an enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individuals culture (2) exhibits a pattern that is inflexible,stable (3) has charactericts that are especially apparent in some sitations their ability to cope 3 Cluster of Persoanlity Disorder A cluster: Odd or eccentric disorders - schiozoid p. disorder - paranoid p. disorder - schizotypal p. disorder B cluster: Dramatic, emotional or erratic disorders - antisocial p.d borderline p.d historic p.d. narcisstic p.d C cluster: anxious or fearful disorders -

problematic patterns of social interactions - dramatic and impulsive behavior Antisocial P.D-> disregard for the other person ,detachment and moral insanity , psychopathy Borderline P.D -> instability in mood,relationships, self, self harm prevalent , without solid sense of self Histrinoic P.D -> pervasive pattern excessive emotionality and attention seeking Narcisstistic P.D -> pervasive pattern of grandiosity , ignoting needs of other , loss of close contact with others ANXIOUS FEARFUL PERSOANLITY DISORDER Avoidant P.D-> pattern of social inhibition, fear of critisim Dependent P.D -> pattern of being submissive , didiculties making everday decisions Obsessive-Compulsive P.D-> preoccupation with orderliness , different from OCD TREATMENT OF PERSONALITY DISORDERS - -Psychotherapy more individually focused -treatment focused on conceptualzations -medications used only as adjunct Dialectical Behavior Therapy -> balancing of opposites , effective in reducing suicide - Dynamic deconstructive psychotherapy - transference-focused psychotherapy : client and therapist relationship NEUROCOGNITIVE DISORDERS Ch 15 Neurocognitice disorder -> decline in brain function Dementia -> a loss of cognitive abilities not related to normal aging Sucessful aging -> high cog and physical functioning Factors affecting aging : genes,experiences,lifestyle,choice Cognitive Abilities (1) vocabulary (2) perceptual speed (3) episodic memory (4) spatial visualization (5) reasoning How the brain changes? - -changes in brain structure -volume reduction in brain areas -reduction of dopamine with age -compensation DELIRIUM is a short term condition characterized by a change in cognitive processing ( inability to focus attenition, problems withn language,memory or orientation) and be caused by a number of pshysiological disturbances develops over short period of time disturbance of consciosusness MILD AND MAJOR NEUROCOGNITIVE DISORDERS Mild n.d. -> a diagnois made when the cog or social deficits in an individual are greater than those declines seen with normal aging Major n.d. -> disgnois made when an individual cog or social deficits are severe and interfere with one’s ability to function independlty -decline in social processes -diagnnis as a two-step process -decline in prevalence -cognitvce changes and mental illness Neurocognitce Disorder due to Alzeimer d. -> problems with memory, Vascular n.d. -> vascular problems such as strokes Fronttemporal n.d.-> different variants depending on the brain areas N.D due to traumatic bain injury TBI-> onte-time only traumatic event N.D due to Lewy Body dementia -> Lewy bodies in neuron, changes in alertness and attention Parkinson disases : is a condition that affect the motor system Hurntington: is a genetic disorder causes of degeneration, resulting in cog, emotional,motor disturbances , has a single cause : A GENE Creutyfeldt-Jakob disease: brain degeneration, genetic component TREATMENT -cog training -deep brain stimulation -
