high - Correct answer Psychotropic medications are believed to be about 50-60% effective in treating OCD, however, if a patient stops the medication the relapse rate is very ________. GABA - Correct answer Benzodiazepine receptors are co-located with _______ receptors which usually function as presynaptic inhibiting receptors. chloride ions - Correct answer Benzodiazepines enhance the effect of GABA and increase the influx of ____________. antihistamines - Correct answer these drugs work by blocking histamine receptors in the CNS beta-blockers - Correct answer These medications act by blocking the effects of norepinephrine at the receptor. They are good at reducing physical symptoms of anxiety, but not cognitive symptoms. clonidine - Correct answer This medication functions as a presynaptic inhibitor of norepinephrine release. stressful event, outcry, intrusion or denial, working through, completion - Correct answer What are the stages of the stress response syndrome? outcry - Correct answer this stage of the stress response syndrome is characterized by an eruption of intense, unpleasant emotion and denial intrusion - Correct answer this stage of the stress response syndrome occurs when a person experiences waves of intense emotion and a strong impulse to think about, imagine, remember, or mentally relive the stressful event. denial - Correct answer in the stress response syndrome, __________ may occur directly following outcry or may come on the heels of a period of intrusion. denial - Correct answer in the stress response syndrome, this stage is characterized by a state

of emotional numbness; people often feel nothing. neurobiology - Correct answer PTSD due to early, severe child abuse or neglect may leave not only emotional scars, but also ____________ may be altered. attachment and protection - Correct answer Severe stress during childhood and infancy in both humans and animals can result in an increased need for __________________________. separation-stress center - Correct answer The repetitive involvement in apparently aversive or abusive relationships may be related to hypersensitivity of the __________________ in the brain, which has been shown to respond favorably to treatment with antidepressants, especially MAO inhibitors and SSRIs. CRF, hippocampus - Correct answer Following early trauma, permanent alterations in the nervous system have also been documented, including persistent elevations in the neuropeptide ______ and atrophy of the ________________. emotion regulation - Correct answer When a traumatic experience occurs early in life a consequence, may be inadequate attachment and bonding. Insecure attachment may lead to difficulties with _____________, which may explain some of the behaviors seen in PTSD. hyperarousal - Correct answer Research has shown that mammals who are exposed to inescapable shock eventually show a depletion in norepinephrine which leads to changes in receptor sensitivity and may lead to chronic __________________. hyperarousal - Correct answer this symptom of PTSD may be due to more or less permanent dysregulation of the hypothalamic-pituitaryadrenal axis damage to the hippocampus and anterior cingulated gyrus

Second-generation antipsychotics, anticonvulsants - Correct answer what medications can be used to treat treatment-resistant PTSD? response to stressful stimuli - Correct answer Animal models strongly support the notion that severely traumatic experiences alter brain functioning and may permanently change an organism's biologic capacity for _______________________. control - Correct answer Central to appropriate pharmacological treatment of PTSD is the restoration of some sense of __________ over turbulent emotions. enlarged lateral ventricles and cortical sulci - Correct answer What did CT and MRI scans find in people with schizophrenia that suggests that either there is brain atrophy or that in some types of schizophrenia there has been abnormal brain development anterior hippocampi - Correct answer MRI scans have shown the presence of smaller ___________________ schizophrenic subjects, which correlates with cognitive impairment SSRI antidepressants, second generation antipsychotics - Correct answer what medications can be used for Intrusive experiences: "flashbacks," avoidance, and numbing seen in PTSD? prefrontal cortex - Correct answer {ET scan studies of people with schizophrenia have shown decreased metabolic activity in the _______________, which correlates with the severity of negative symptoms. HVA - Correct answer in people with schizophrenia, studies have found a positive correlation between levels of ________ in plasma and clinical severity. the dopamine model - Correct answer this theory hypothesized that schizophrenia is caused by abnormal dopaminergic activity in the brain

emotional control, screening of stimuli - Correct answer In areas of the limbic and reticular systems, dopamine neurons appear to play an important role in ____________ and the ______________. overactive - Correct answer The dopamine model of schizophrenia holds that the basic physiological pathology involves primarily __________ dopamine neurons. dopamine - Correct answer excessive ___________ activity can lead to behavioral agitation, a failure to adequately screen stimuli, and disorganization of perception and thought block - Correct answer the potency of antipsychotic drugs has correlated closely with their ability to bind to and _________ the postsynaptic dopamine (D2) receptors in the mesolimbic system dopamine activity - Correct answer drugs that increase _______________________ can produce a paranoid psychosis similar to paranoid schizophrenia and, if given to schizophrenic patients, amphetamines may exacerbate psychotic symptoms. positive, negative - Correct answer In schizophrenia there appears to be an increase in dopamine activity in the mesolimbic tracts which leads to __________ symptoms, but a decreased dopamine activity in the prefrontal cortex which leads to __________ symptoms glutamate system - Correct answer It is hypothesized that in schizophrenia there is a primary dysregulation of the ____________________ resulting in cognitive deficits and that the dopaminergic hyperactivity, and resultant positive symptoms, are secondary phenomena brain - Correct answer There is now evidence to support the notion that being psychotic is
