Q

What are the etiologies (causes) of schizophrenia?

A

1) Biological factors
-Genetics, diathesis-stress (nature vs nurture theory)
-Epidemiological factors such as toxins/drugs, trauma, stress.

2) Neurobiological Theories:
-Dopamine theory (1st gen. Antipsychotics): Theory suggests that it is caused by too much dopamine in the brain. HOWEVER, the problem with this theory is that some of the antipsychotics help produce dopemine…and the results work really well.
-Other neurochemical hypothesis (2nd gen. Antipsychotics): where basically the seotonins a bit low, GABA’s probably too high, dopamines probably a bit too high. Righting those levels are the treatment path.

3) Brain structural abnormalities:
-I.E abnormalities in the white matter, networking/connectivity, prefrontal cortex, etc.

4) Psychological and environmental stressors:
- Prenatal stressors
- Psychological stressors
- Environmental stressors
- Prognostic considerations

Q

What are the phases of schizophrenia?

A

1) Prodromal Phase:
-Onset; Starts with some mild changes (Pos/Neg, SX’s, alterations in speech/thought process)
-Early assessment and interventions are key
-Establish rapport
-Reduce risk factors such as high stress level, substance abuse. Chances of interventions at this stage can be extremely halpful in treatment. Trust is imparative.

2) Acute Phase:
-Exacerbation of symptoms, affect is blunted even more. Were in the hospital now.

3) Stabilization Phase:
-Symptoms are diminishing and they’re moving towards previous level of functioning. Prescription drugs are most effective treatment.

4) Maintanence or residual Phase:
-This is where a new baseline is established.

5) Pressured speech
6) Flight of ideas
7) Circumstantiality
8) Tangentiality
9) Cognitive retardation
10) Symbolic speech

A

1) Associative looseness- A jumble of words, or word salad, meaningless to the listener. “Castle had mark port”

2) Clang association- Words chosen based on sound. “I was mad, because im bad, I like cad, that was rad”

3) Neologisms- Made up words only the patient knows. “Hes a forp you know, a complete fogger”

4) Echiolalia- Pathological repeitition of anothers words. (You say “I need to take your vitals”, and the patient incessantly repeats that sentence or part of the sentence, “Vitals, I need to take your vitals, vitals…”)

5) Pressured speech- Sense of urgency in speech

6) Flight of ideas- A ton of different things they want to talk about so it just jumps from one topic to another, to another and fast. Common in mania.

7) Circumstantiality- Including unnecessary and often tedious details in conversation, but eventually reaching the point.

8) Tangentiality- Wandering off topic or going off on tangents and never reaching the point.

9) Cognitive retardation- Generalized slowing of thinking, which is represented by delays in responding to questions or difficulty finishing thoughts.

10) Symbolic speech- Using symbols instead of direct communication. For example, a patient reports “demons are sticking needles in me” when what he means is that he is experiencing a sharp pain (symbolized by “needles”).

18
Q

What are the first-generation antipsychotics?

A

1) Thorazine, haldol-Typically used on a PRN basis because they are highly sedating. NOT FOR LONGTERM due to EPS and TD.

-Target positive symptoms of schizophrenia

Advantage:
-None that matter

Disadvantages:
- Extrapyrimidal side effects
- Anticholinergic (ACh) side effects
- Tardive dyskinesia
-Weight gain, sexual disfuction, endocrine disturbances

A

Clozapine, Aripiprazole, Paliperidone, Risperidone, Ziprasidone, Quetiapine.
Good at controlling both the positive and negative symptoms but they tend to have a considerable side effect index.
-Serotonin (5-HT receptor) and dopamine (D2 receptor) antagonists, e.g clozapine (Clozaril)
-Treat both positive and negative symptoms
-Minimal to no EPS or tardive dyskinesia
-Disadvantages-tendency to cause significant weight gain; risk of metabolic syndrome, hyperlipidemia, gynacomastia, lactation for male and female.
