Question description

- Week 5 - Discussion 1

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Reference the Discussion Forum Grading Rubric for guidance on how your discussion will be evaluated.

Schizophrenia and Smoking

After reading Chapter 11 and 12 in your course text and the article “Considering the Definition of Addiction” which covers the biological basis of emotion, addiction (substance abuse disorder), and disordered behavior, analyze the high rate of smoking in those diagnosed with schizophrenia compared to the general population.  Why are smoking cessation interventions less successful in these individuals? Review the accepted mechanisms of tobacco abuse and dependence and the etiologic theories of schizophrenia. What are the biological and/or psychological mechanisms between schizophrenia and smoking?  Include information on brain structures, pathways, neurotransmitters/receptors, and psychological factors when discussing the topic areas above.  Additional emphasis should be placed on relating the underlying pathology of schizophrenia to tobacco dependence/abuse and the biological or psychological mechanism of the observed association of smoking behavior to the diagnosis of schizophrenia.   

In keeping with the focus of this class, the emphasis should be placed on the role of neurotransmitter and receptor systems, neuroanatomical structures, and neurological functional pathways.  You must use a minimum of one peer-reviewed source that was published within the last five years, documented in APA style, as outlined in the Ashford Writing Center. How does the data support the proposed mechanism in the article you chose?  What other possible mechanisms might explain this relationship?  Is it possible that biology has nothing to do with the relationship between smoking and schizophrenia?  Your post should be a minimum of 250 words.  You may cite and reference your textbook, required reading and/or multimedia, but these will not fulfill the source requirement.  

Guided Response:  Respond substantively to a minimum of two classmate’s original posts that have identified different neurotransmitters than you.  Your responses should address both the neurotransmitter/receptor system and neuroanatomical structures involved for the analysis of the association of smoking behavior and schizophrenia. In addition, please observe the following guidelines for all responses:

  • Provide a courteous and interactive learning environment.
  • Continue to monitor the discussion board and reply to anyone who has chosen to respond to your original post.   
  • Your responses should address both the neurotransmitter and receptor system in their discussion, and the biological and/or psychological mechanism that potentially explains the connection between tobacco abuse, dependence, and schizophrenia.  
  • Your responses should demonstrate that you have read the existing replies on the board (in your response, mention information and viewpoints already expressed by existing responses to the same post).
