Schizophrenia non-genetic correlates
-Families with Expressed Emotion (EE) (?)
- Virus (during 2nd trimester)
- Pregnancy complications
- Birth complications
- Stress vulnerability (inc. genetic vulnerability to developing psychosis when stressed)
Percent of population w/ Schiz.
1.3%
(of that percentage 8% are sibling of patinet, 45-50% identical twin of patient, 15% paternal twin of patient, 12% child w/ ill parent, 40-45% child w/ 2 ill parents)
Dopamine levels & Schizophrenia - explain the correlation
Foundation of Schiz is associated with Dopmine receptors in the temporal lobe and basal ganglia - Temporal lobe is accelerating, frontal lobe is slowing down -> the disconnect betwen the 2
Associated Neurotransmitters
- GABA : loss of GABA -> hyperactivity of dopamine
- Serotonin (5HT)
- Norepinephrine (NE)
(NE and 5HT modulate Dopamine system)
- Glutamate: abnormal neural maturation (mostly seen in young men w/ shiz.)
Schizophrenia biological correlations
Hypofrontality: frontal lobe shown to have dec. blood flow and glucose metablolism.
Temporal lobe is smaller in size : not seen in all patients -> affects information processing (hypoactivity -> memory difficult b/c cognition impaired)
Bilateral hemisphere - prefrontal and frontal dysfunctions.
Positive and Negative Symptoms

-distinguishing characteristics
- types of each
- Positive - result of overactivity, acute onset, normal social functioning during remission, favorable response to antipsychotic meds,
hallucinations, delusions, bizarre/ disorganized behav., positive formal thought disorder.
- Negative - result of underactivity; gradual onset, premorbid history of emotional problems, chronic deterioration, atrophy on CT scans, harder to treat, last longer, more severe
- The 5 A's on separate card

- POSITIVE FORMAL THOUGHT DISORDER

- Word Salad: jumble of words that is meaningless
- Flight of Ideas:
- Neologism: making up words
- Clang Association: using words that sound the same
- Echolalia: repeat everything you say

Nursing Interventions

-Anxiety
- Mistrust
They will test their boundaries. They are trying to establish if they can trust you. Will be seeing if you follow through w/ what you say.
Short brief periods of interaction – that is all they can tolerate.
Need be very aware of what you are doing nonverbally, the patients are watching you – they may perceive as threatening or you are laughing at them.
Nursing interventions for LOOSE ASSOCIATIONS
If you don’t understand, “I am having difficulty understanding….” Put the focus on your lack not theirs.
Do point out what you understand to enhance the positive.
Nursing Interventions for HALLUCINATIONS
Hallucinations – “hearing voices”
• What are they saying? (commanding or demanding – need to know for safety)
• Are you frightened by them?
• Don’t reinforce what is not real – “I understand what you believe, but I am not seeing/ hearing that.”
• If not sure how to bring back to reality say something as simple as “I like your shoes” their shoes are real, interrupts and brings back to reality.
• Some will be told to interact w/ their voices – to tell them to STOP! And leave them alone. Be careful where they are instructed to do so.
• Auditory hallucinations can be helped by simply wearing ear plugs, it tell the brain they cant hear – shuts off the voices.
