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 |
|

|

men 15-25 yo
women 25-35 |
|
Dual diagnosis often associated with Schizophrenia
|
- ETOH abuse/ dependence (40-50%)
- 15-25% marijuana abuse - 5-10% cocaine abuse - 80-90% nicotine dependence people w/ dual diagnosis have more pronounced psychotic episodes, less compliant w/ treatment. Smoking can dec. effects of meds. |
|

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. |
