Psychotic/ Musculoskeletal Disorders Flashcards
Risk Factors for _______:
- Urban living
- Immigration
- Obstetrical complications
- Viral exposure in utero (flu)
- AMA
- Birth during famines
Schizophrenia
large extra cellular matric glycoprotein involved in neuronal migration during prenatal development of brain & in synaptic function duing adulthood - low levels of this in prefrontal cortex and hippocampus in schizophrenia
reelin
schizophrenia chromosomes are ___, ____, and ____.
18,22, 23
neurotransmitter alterations schizophrenia theory that states transmission pathways are altered causing increase in dopamine
dopamine hypothesis
neurotransmitter alterations schizophrenia theory that states under-activated glutamate receptors (N-methyl-D-aspartate (NMDA) receptor subtype) causes lower levels of glutamate
glutamate hypothesis
type of schizo symptoms that frequently occur during a psychotic episode (loses touch with reality and experiences something that should be absent
positive symptoms
positive symptoms of schizo
hallucinations
delusions
disorganized speech/behavior
symptoms of schizo that are disruptions in normal emotional states and expressions including social withdrawal, blunted affect, no response to simple questions
negative symptoms
negative symptoms of schizo
affective flattening
anhedonia
alogia
avolition
low levels of ______ in schizo is related to chromosome 22
reelin
if this brain component, which is central in social brain processing, is abnormal, the person has difficulties making appropriate social judgements, ie. facial identity, affect recognition, emotional processing
amygdala
symptoms of schizo that are problems with thought processes that severely impair the ability to
perform routine daily tasks that involve attention, planning, and social skills
cognitive symptoms
etiology of ________ and _______ is related to deficits of reelin expression on chromosomes 18 and 22
depression and bipolar
chromosome 22 is related to _____ behavior
psychotic
dysfunction of this has a role in individuals ability to cope with stress
hypothalmic-pituitary system
chronic stress-induced actication of this sytem leads to increased glucocorticoid secretion associated with 30-70% of those with major depression
hypothalmic-pituitary system
in depression/bipolar, this system increases HPA hormone secretions
hypothalmic-pituitary system
this causes depression/bipolar when inflammation increases C-reactive protein -> increased risk for psych distress and depression
-increased cytokine levels may be associated with depression
Altered immune and Inflammation from Cortisol
there is an association of _______ function and mental illness but the mechanism is unknown
thyroid
patients with _______, have anxiety, dysphoria, irritability, cognitice impairments
hyperthyroidism
patients with _____, have depression, apathy, psychomotor slowing, dementia
hypothyroidism
in depression/bipolar, a large group of serotonin-synthesizing neurons, in the _________, that project extensively to all regions of the cortex
central gray matter
in depression/bipolar, widespread decrease in _______, 5-HT1A receptor subtype in the frontal, temporal, and limbic cortex
serotonin
in depression/bipolar, _______ transporter binding in cerebral cortex and hippocampus
serotonin
some people with depression/bipolar have dysfunction of ________, which modulates homeostasis, emotionality, and tolerance to aversive experiences.
raphe-serotonin system
in depression/bipolar, functional abnormalities are found in _____ and _____ regions such as the amygdala
frontal and limbic
decreased _______ numbers occurs in in people w/uni & bipolar
glial cell
in mood disorders and bipolar, cerebral blood flow _______ in dorsolateral and dorsomedial prefrontal cortex
decreases
in unipolar depression, cerebral blood flow ________ in ventrolateral, ventromedial, and orbital areas
increases
major excitatory neurotransmitter associsated with MDD
glutamate
elevated cortical levels of ______ occur in mood disorders
glutamate
_______ (glutamate receptor antagonist) was found in animal models to rapidly increase synaptic density and signaling
ketamine
psychosocial stress can cause _______ in pro-inflammatory cytokines
increase
- Deficit in norepinephrine, dopamine, and/or serotonin may be the cause
- Found that drugs, like imipramine elevated norepinephrine levels reduced depression, but drugs that depleted monoamine levels increased depression.
- Mania results from ↑ monoamine
Dominant MonoAmine Hypotheseis of Depression
the principle of antidepressant medication is increasing ______ neurotransmitter levels within the synapse is the basis for their antidepressant effects
monoamine
inability to experience emotion(pain or pleasure, repost a sense of detachment from environment
adhedonia
