THE PATIENT EXPERIENCING SCHIZOPHRENIA
SCHIZOPHRENIA
• Thought process disorder
Schizophrenia means “splitting of the mind” & reflects its effects on thought & language
• Major cause of prolonged psychosis
Loss of rational thought & the ability to accurately interpret the environment
• Characterized by: disordered thoughts, delusions, and hallucinations
• Dispelling common myths about schizophrenia
Schizophrenia does not mean spilt personality
Schizophrenics are not usually prone to violence
Schizophrenia is not caused by family dysfunction
DISORDERED THOUGHTS
• Major characteristic of schizophrenia
• “Loose” flow of thoughts
Topics & ideas flow from one to another with little or no order
• Ideas are unrelated
May make sense individually, but not when put together
• Evolves slowly over years
Thought disorders may be subtle & hard to recognize in early stages
• May lose ability to communicate as the condition evolves
INCOMPREHENSIBLE LANGUAGE
• Neologisms
•
•
•
•
Individuals frequently invent their own vocabularies – may offer definitions
Derailment
Going off the point or subject
Tangentiality
Failure to reach a goal or stick to the original point
Incoherence
Speech that is not logically connected
Word salad
A group of disconnected words
LOSS OF FUNCTION
• Cannot maintain social norms
Due to loss of ability to think & communicate
• Behavior disordered
Social & verbal
• Inappropriate appearance and dress
May range from sloppy to eccentric or even bizarre
• Catatonia may be present
Among the most striking manifestations of psychosis
Marked decrease in reactivity to environment – to complete unawareness
Maintains rigid posture & resists efforts to be moved
DELUSIONS
• Fixed, false beliefs
Misrepresent either experiences or perceptions
• Major defining characteristic of psychosis
Grandiose – involve perceptions of importance; often believe they have special powers & may claim to be a
religious Messiah
Persecutory – paranoid; believe that others intend to do them harm
Referential – believe that common events have reference to them
Examples: passages in songs, patterns of clouds in the sky, comments of others
HALLUCINATIONS
• Another major characteristic of psychosis
• Very common in schizophrenia
• Sensory experiences not perceptible to others
Can involve any sensory modality
• Auditory most common
May be one or more voices:
may be talking with each other or commenting on the individual’s
stream of thought
Voices are perceived as very distinct from the individual’s own thoughts
Voices usually have a specific content – most frequently a threatening or negative nature
Voices emanate from inside the body or from the sky
Occur while fully awake
SYMPTOMS OF SCHIZOPHRENIA
Positive symptoms
• Disordered thought/behavior
• Delusions
• Hallucinations
Negative symptoms
• Flattened affect
Loss of expressiveness
• Alogia
Tendency to speak very little
• Avolition
Tendency to lack motivation for work or other activities that are goal-directed
• Anhedonia
Inability to find joy in activities that are pleasurable to unaffected persons
CLINICAL COURSE
• Organic disease with genetic component
• Appears in early to mid-twenties in men
• Later in women – typically the late twenties
• Outcome improved in past 20 years
• Course of illness unpredictable
• Increased risk of suicide
• High social cost
Current Views on Causes
Genetics
• Overall lifetime risk of developing schizophrenia is 1%
• An individual with 2 schizophrenic parents has a 50% chance of becoming schizophrenic
• Clearly a disorder with a major genetic component
• Highest risk occurs in identical twins with both parents having schizophrenia
• Currently believed that 70% of risk for developing schizophrenia is due to genetic factors
• However, the majority of schizophrenics have absolutely no family history (63%)
• No certain answer has emerged to date
Organic Causes
• Something physically & structurally wrong with the brain
• Little progress until CT scanners were brought into use in the mid-1970s to evaluate the brains of
schizophrenics
• Males with schizophrenia have larger lateral ventricles than those that do not have schizophrenia – but not females
• The meaning of this finding remains unclear – is it a cause or a consequence of schizophrenia?
• Some evidence indicates that ventricular enlargement may progress during the course of the disease & cause some
cerebral atrophy
• Schizophrenia could come to be viewed as a progressive degenerative neurological disease
Dopamine Hypothesis
• States that the functional abnormalities in schizophrenia are due to excessive activity of brain dopamine
• Dopamine is normally produced in the brain & serves as a neurotransmitter
• Dopamine has its most important effects in the basal ganglia of the brain – reduction of dopamine in these
structures leads to Parkinson’s
• Drugs effective in controlling the positive symptoms all seem to have significant dopamine receptor blocking
activity – they work by reducing the effect of the individual’s own dopamine on his or her brain
• Drugs that can cause schizophrenic-like psychoses act by increasing brain dopamine concentrations
(amphetamines)
• Multiple autopsies have shown an increase in the brain’s basal ganglia in persons dying with schizophrenia
Other Neurotransmitters
• Dopamine levels & receptor numbers may be affected by other processes
Especially those in the prefrontal & cortical areas, which have shown to be abnormal in imaging studies
• Recent research shows a decrease in the number of inhibitory neurons in schizophrenia
• Expression of choleycystokinin & somatostatin is also decreased in schizophrenia
Loss of inhibitory function may account for increased brain activity seen in the hippocampus & parts of the
prefrontal cortex
TREATMENT
Psychosocial
• Clinical & Family support
• Providing specific skills training for patient & family stress management & functional coping responses
are high priority
• Educating family about the nature & meaning of the disease
• Assisting family members is a nursing care priority
• Educating families on the purpose & side effects of medication
• Rehabilitative services
• Primary focus is on enhancing social skills – negative symptoms
• May be directed toward vocational goals for some individuals
• Humanitarian aid/public safety
• Deinstitutionalization
• Least restrictive care needed to provide psychosocial & rehab services - often means
• homeless
• starving
• without treatment
Nursing Alert !!!
• Tardive Dyskinesia - Frequently cannot be reversed by withdrawing medications
ASSESSMENT
• Delusional thought
• Hallucinations
• Disorganized speech
• Grooming
• Negative symptoms of schizophrenia
• Level of independence and functioning
NURSING DIAGNOSIS
• Disturbed thought processes, sensory perceptions, sleep patterns
• Self-care deficit (specify)
• Ineffective role performance
• Social isolation
• Ineffective therapeutic regimen management
OUTCOME IDENTIFICATION
• Set appropriate goals
• Outcomes differ for acute and rehabilitative phases
Acute phase – immediate goal of treatment is to bring symptoms under control
Rehab phase – goals aimed at helping the patient & his family to make the best adjustment possible to a
chronic disease
PLANNING/INTERVENTIONS
• All based on alleviating acute symptoms
• Establish safe and trusting environment
EVALUATION
• Have identified outcomes been met?
