Psychosis and Schizophrenia Flashcards

1
Q

Which two theories outline the pathogenesis of Schizophrenia and its subsequent Rx?

A
  1. DA Theory
    • Amphetamine –> Schizophrenia Sx
    • D2-receptor agonists –> Similar Symptoms
    • Strength of Neuroleptics and D2 antagonist action
    • Increased Dopamine content in amygdala (temporal lobe)
    • Increased Dopamine content in Striatum of Schizophrenics
  2. Glutamate Theory
    • NMDA receptor antagonists (phencyclidine/ketamine) –> psychotic Sx
    • Reduced glutamate receptor density and expression –> Schizophrenic brain slices
    • TG mice with NMDA receptor expression –> Schizophrenic behaviours
    –> Restored with antipsychotics/neuroleptics

Q

List the 4 Dopamine pathways which are affected in Schizophrenia. What do each do?
