PSY2003 W1 Schizophrenia 2 - R Flashcards
What did Thompson et al. use to study gray matter in schizophrenia?
Brian mapping algorithms of anatomical profiles
What did Thompson et al. detect ?
Aceelerated grey matter loss in very early-onset schizophrenia
Where was the earliest deficits founds?
In parietal brain region (visuospatial and associative thinking)
Where was the next deficit found?
anteriorly into temporal lobes (sensorimotor and dorsolateral prefrontal cortices and frontal eye fields)
What did the deficits visible in the brain mapping correlated with?
with the psychotic symptom severity and reflected the impairments in the disease (neuromotor, auditory, visual search and frontal executive impairments)
What is the typical onset of schizophrenia
Late adolescence/early adulthood
What is a early-onset of schizophrenia like?
Childhood onset schizophrenia is a sever form of the disorder
What were the results of gray matter loss for normal adolescents ?
There was a subtle but significant change detected in normal adolescents.
What were the results for the schizophrenic patients?
striking accelerated loss of grey matter in the frontal eye fields and supplementary motor, sensorimotor, parietal and temporal cortices in both brain hemisphere
