What is schizophrenia and what is the average lifespan?
- thought disorder
- average lifespan on 53 years
If a person has a mental disorder, what should the nurse do FIRST?
- Assess: medications, alcohol withdrawal, UTIs, sepsis, dementia, injury, trauma
Cormorbidity
-the appearance of multiple simultaneous psychological disorders in the same person
-Substance abuse disorders
Nicotine dependence
Alcohol abuse
Anxiety disorder (OCD)
Major Depressive Disorder
Physical illness
Suicide
Brain Structure Abnormalities Course of the Disorder: Prodromal
Early symptoms
¡ Decrease functioning's, onset of psychotic symptoms- hallucinations, delusions, eccentric
(odd), social withdrawal, irritable, anxious
,¡ Fast onset= increases morbidity
¡ The younger the patient is onset, the worse the prognosis
Neurobiological and brain abnormality theory
- common among schizophrenics
- Disruptions in the pathways of the brain is schizophrenia are thought to be severe. It is possible
that structural abnormalities cause such disruptions.
Structural brain abnormalities such as:
-Enlargement of the lateral cerebral ventricles, Third ventricle dilation, and/or ventricular
asymmetry
-Reduction in the cortical, frontal lobe, hippocampal and/or cerebellar volumes
-Reduced cortical thickness and reduced connectivity in various brain regions
-Increased dopamine activity in the mesolimbic system (good to know these facts)
Phases of Schizophrenia: Phase 1
- Acute
- Onset or exacerbation of symptoms - premorbid symptoms, hallucinations, delusions,
disorganized behavior, perception problems = may need hospitalization
Phases of Schizophrenia: Phase 2
- Stabilization
- Symptoms diminishing
- Movement toward previous level of functioning
Phases of Schizophrenia: Phase 3
, - Maintenance
- At or near baseline functioning- get person on discharge = outpatient level of care, follow up
with psychiatrist, get pt to stay on meds, and prevent reoccurance of hospitalization
DSM-5 Criterion
-Symptoms present for at least 6 months
-Active-phase symptoms present at least 1 month.
-Symptoms are defined as positive and negative
Positive Symptoms
normal functioning individual, it is something that is added on or extra
positive symptoms of schizophrenia
delusions, alterations in speech, alterations in perception
grandiose delusions
false, persistent beliefs that one has superior talents and traits
"I am the best instructor"
persecutory delusions
beliefs of being targeted by others
referential delusions
