Pathways Flashcards
What pathway is associated positive symptoms
Mesolimbic
What pathway is associated with negative symptoms
Mesocortical
What pathway is associated with abnormal movements
nigrostratial pathway.
What pathway is associated with prolactin
tuberofundibular pathway
How does antipsychotic cause abnormal movements
They block dopamine from being released in the nigrostratial pathway
How does dopamine cause breast or milking in males
By blocking dopamine in tuberofundibular pathway, prolactin is not inhibited. Therefore too much prolactin build up can lead to this.
Consider : dopamine is what helps inhibit prolactin build up, without it can lead to its excess
How does antipsychotic cause blunting and lack of emotions
Blocking dopamine in the mesocortical pathway.
How does antipsychotic decrease the positive symptoms we see in schizophrenia patients?
Blocking the excessive release of dopamine in the mesolimbic system
