Mayo Neuro Board Review Flashcards
Neurochemical considerations in schizophrenia
excess of dopamine linked to psychotic symptoms
Types of Dopamine Receptors
D1 cerebral cortex and basal ganglia
D2 striatum
D3 and D4 high concentration in the limbic system
D5 located in thalamus hippocampus and hypothalamus
First line treatments for Schizophrenia
atypicals
risperidone olanzapine quetiapine ziprasidone aripiprasole
second line schizophrenia tx
clozapine
needs monitoring agranulocytosis
Typicals (may worsen neurocognitive functioning)
chlorpromazine thioridazine perphenazine trifluoperazine thiothixene haloperidol fluphenazine
Associated Neuorlogic findings in Schizophrenia
ventricular enlargement
frontal lobe abnormality
decreased volume of basal ganglia, limbic areas, hippocampus, thalamus, temporal regions, parahippocampal gyrus
Hypofrontality: frontal lobe dysfunction
Increased D2 receptor density in striatum and nucleus accumbens
Abnormal saccadic eye movements
primtive reflexes
