SCHIZOPHRENIA - FINAL EXAM
QUESTIONS AND ANSWERS
Schizophrenia is - ANSWER-a disease of the brain manifested in symptoms of the
mind
dopamine and schizophrenia - ANSWER-excess of receptors for dopamine
intensifies brain signals and creates positive symptoms
drugs and schizophrenia - ANSWER-drugs that block dopamine often lessen the
symptoms, but drugs that increase dopamine (like amphetamines and cocaine)
intensify them
brain activity and schizophrenia - ANSWER-abnormally low activity in frontal lobes,
noticeable decline in brain waves that reflect synchronized neural firing in frontal
lobes, out of sync neurons may disrupt the integrated functioning of neural networks
what is an area of the brain become active during hallucinations? - ANSWER-
thalamus
what is an area of the brain that becomes more active with paranoia? - ANSWER-
amygdala
brain anatomy and schizophrenia - ANSWER-enlarged, fluid filled areas and
corresponding shrinkage and thinning of cerebral tissue, inherited, the greater the
shrinkage the more severe the disorder.
what areas of the brain are smaller than normal? - ANSWER-the cortex and the
corpus callosum (connects two hemispheres). thalamus (may explain why people
have difficulty filtering sensory output and focusing attention)
prenatal environment and risk - ANSWER-low birth weight, maternal diabetes, older
paternal age, oxygen deprivation during delivery, famine, flu epidemic, dense
population, fetus-viral infections
shared placental and schizophrenia - ANSWER-shared placenta increases the risk
of schizophrenia for identical twins because they share the same germs and genes
schizophrenia is influenced by - ANSWER-many genes, each with very small effects
what factors can "turn on" genes that put some of us at a higher risk for
schizophrenia? - ANSWER-viral infections, nutritional deprivation, and maternal
stress
impaired theory of mind - ANSWER-Difficulty reading other peoples' facial emotions
and states of mind
