Chapter: Schizophrenia, Affective Disorders, and Anxiety Disorders

1. List and describe three positive symptoms of schizophrenia.
2. List and describe three negative symptoms of schizophrenia.
3. Why do we think that schizophrenia is heritable? The genetics of schizophrenia is confusing. Give two ways that the genetic link to schizophrenia might be complicated.
4. Which neurotransmitter has been strongly linked to schizophrenia? The positive symptoms of schizophrenia are reduced by drugs that antagonize what? Name one drug that produces positive symptoms of schizophrenia.
5. What are two gross brain anomalies associated with schizophrenia?
6. Name two environmental factors that are linked to the seasonality effect in schizophrenia.
7. At approximately what age does cortical tissue loss occur for schizophrenics? Do non-schizophrenic folks lose tissue at this approximate age?
8. List the two most common major affective disorders. In your description, include the time-course of the symptoms. Are the symptoms episodic or sustained? Roughly, how long do they last?
9. Provide one direct piece of evidence supporting the hypothesis that there is a genetic component to affective disorders.
10. What is ECT? Why is the speech-dominant hemisphere avoided?
11. Describe three types of drugs used to treat unipolar depression. Describe their pharmacological effects at the level of the terminal button.
12. Schizophrenia is linked to one neurotransmitter and major depressive disorder is linked to a class of neurotransmitter. Which neurotransmitters are associated with these two diseases? Is the illness hypothesized to be due to a deficiency or a surplus of the neurotransmitter?
13. What is the brain structure that is important for positive reinforcement during learning because it is active when the animal/person feels good? It is also a target for combating major depressive disorder. What type of procedure utilizes it for treatment?
14. Clomipramine has been used to treat trichotillomania, onychophagia and acral lick dermatitis. What other major anxiety disorder has been treated with this drug? The success of this drug across such a broad range of different compulsive behaviors supports the position that what neurotransmitter is generally associated with obsessive behaviors?
15. Define "partial agonist". Explain how it acts as an agonist in some settings and as an antagonist in other settings.
