Schizophrenia is a complex mental disorder that causes distorted thoughts, perceptions, emotions and behavior. It is diagnosed in late adolescence or early adulthood and symptoms include positive symptoms like delusions and hallucinations as well as negative symptoms like lack of emotion and social withdrawal. There are several types of schizophrenia including paranoid, disorganized and catatonic types which are diagnosed based on the predominant symptoms. Treatment involves antipsychotic medication as well as psychosocial therapies and nursing interventions are aimed at building trust, emphasizing reality, and preventing injury during periods of agitation or excitement.

Schizophrenia
DEFINITION
Schizophrenia is an extremely complex mental disorder: in fact it is probably many
illnesses masquerading as one. A biochemical imbalance in the brain is believed to cause
symptoms. Recent research reveals that schizophrenia may be a result of faulty neuronal
development in the fetal brain, which develops into full-blown illness in late adolescence
or early adulthood.
Schizophrenia causes distorted and bizarre thoughts, perceptions, emotions, movement,
and behavior. It cannot be defined as a single illness;
rather thought as a syndrome or disease process with many different varieties and
symptoms. It is usually diagnosed in late adolescence or early adulthood. Rarely does it
manifest in childhood. The peak incidence of onset is 15 to 25 years of age for men and
25 to 35 years of age for women.
The symptoms of schizophrenia are categorized into two major categories, the positive
or hard symptoms which include delusion, hallucinations, and grossly disorganized
thinking, speech, and behavior, and negative or soft symptoms as flat affect, lack of
volition, and social withdrawal or discomfort. Medication treatment can control the
positive symptoms but frequently the negative symptoms persist after positive symptoms
have abated. The persistence of these negative symptoms over time presents a major
barrier to recovery and improved the functioning of client’s daily life.

PATHOPHYSIOLOGY

3. www.drjayeshpatidar.blogspot.com
TYPES OF SCHIZOPHRENIA:
The diagnosis is made according to the client’s predominant symptoms:
Schizophrenia, paranoid type is characterized by persecutory (feeling victimized or spied
on) or grandiose delusions, hallucinations, and occasionally, excessively religiosity
(delusional focus) or hostile and aggressive behavior.
Schizophrenia, disorganized type is characterized by grossly inappropriate or flat affect,
incoherence, loose associations, and extremely disorganized behavior.
Schizophrenia, catatonic type is characterized by marked psychomotor disturbance,
either motionless or excessive motor activity. Motor immobility may be manifested by
catalepsy (waxy flexibility) or stupor.
Schizophrenia, undifferentiated type is characterized by mixed schizophrenic symptoms
(of other types) along with disturbances of thought, affect, and behavior.
Schizophrenia, residual type is characterized by at least one previous, though not a
current, episode, social withdrawal, flat affect and looseness of associations.
Paranoid Schizophrenia
Is characterized by persecutory or grandiose delusional thought content and, possibly,
delusional jealousy.
Some patients also have gender identity problems, such as fears of being thought of as
homosexual or of being approached by homosexuals.
Stress may worsen the patient’s symptoms.
Paranoid schizophrenia may cause only minimal impairment in the patient’s level of
functioning – as long as he doesn’t act on delusional thoughts.
Although patients with paranoid schizophrenia may experience frequent auditory
hallucinations (usually related to a single theme), they typically lack some of the
symptoms of other schizophrenia subtypes – notably, incoherent, loose associations,
flat or grossly inappropriate affect, and catatonic or grossly disorganized behavior.
Tend to be less severely disabled than other schizophrenia.
Those with late onset of disease and good pre-illness functioning (ironically, the very
patients who have the best prognosis) are at the greatest risk for suicide.

6. Avoid crowding him physically or psychologically; he may strike out to protect himself.

5. www.drjayeshpatidar.blogspot.com
7. Respond neutrally to his condescending remarks; don’t let him put you on the
defensive, and don’t take his remarks personally.
8. If he tells you to leave him alone, do leave- but make sure you return soon.
9. Set limits firmly but without anger, avoid a punitive attitude.
10. Be flexible, giving the patient as much control as possible.
11. Consider postponing procedures that require physical contact with hospital personnel if
the patient becomes suspicious or agitated.
12. If the patient has auditory hallucinations, explore the content of the hallucinations
(what voices are saying to him, whether he thinks he must do what they command) tell
him you don’t hear voices, but you know they’re real to him.
Disorganized Schizophrenia
Is marked by incoherent, disorganized speech and behaviors and by blunted or
inappropriate affect.
May have fragmented hallucinations and delusions with no coherent theme.
Usually includes extreme social impairment.
This type of schizophrenia may start early and insidiously, with no significant remissions.

Grossly disorganized behavior.
Blunted, silly, superficial, or inappropriate affect.
Grimacing
Hypochondriacal complaints.
Extreme social withdrawal.
Diagnosis
Ruling out other causes of the patients symptoms.
Meeting the DSM-IV-TR criteria.
Treatment
Treatments described for other types of schizophrenia.
Antipsychotic drugs and psychotherapy.
Nursing Interventions
1. Spend time with the patient even if he’s mute and unresponsive, to promote
reassurance and support.

2. Remember that, despite appearances, the patient is acutely aware of his environment,
assume the patient can hear – speak to him directly and don’t talk about him in his
presence.
3. Emphasize reality during all patient contacts, to reduce distorted perceptions (for
example, say, “The leaves on the trees are turning colors and the air is cooler, It’s fall”)
4. Verbalize for the patient the message that his behavior seems to convey, encourage him
to do the same.
5. Tell the patient directly, specifically, and concisely what needs to be done; don’t give
him choice (for example, say, “It’s time to go for a walk, lets go.”)
6. Assess for signs and symptoms of physical illness; keep in mind that if he’s mute he
won’t complain of pain or physical symptoms.
7. Remember that if he’s in bizarre posture, he may be at risk for pressure ulcers or
decreased circulation.
8. Provide range-of-motion exercises.
9. Encourage to ambulate every 2 hours.
10. During periods of hyperactivity, try to prevent him from experiencing physical
exhaustion and injury.
11. As appropriate, meet his needs for adequate food, fluid, exercise, and elimination;
follow orders with respect to nutrition, urinary catheterization, and enema use.
12. Stay alert for violent outbursts; if these occur, get help promptly to intervene safely for
yourself, the patient, and others.
Catatonic Schizophrenia
Is a rare disease form in which the patient tends to remain in a fixed stupor or position
for long periods, periodically yielding to brief spurts of extreme excitement.
Many catatonic schizophrenia have an increased potential for destructive, violent
behavior when agitated.
Signs and Symptoms
Remaining mute; refusal to move about or tend to personal needs.
Exhibiting bizarre mannerisms, such as facial grimacing and sucking mouth movements.
Rapid swing between stupor and excitement (extreme psychomotor agitation with
excessive, senseless, or incoherent shouting or talking).
Bizarre posture such as holding the body (especially the arms and legs) rigidly in one
position for a long time.
Diminished sensitivity to painful stimuli.
Echolalia (repeating words or phrases spoken by others).
Echopraxia (imitating other’s movements).
Diagnosis
Ruling out other possible causes of the patient’s symptoms.

Meeting the DSM-IV-TR criteria.
Treatment
ECT and benzodiazepines (such as diazepam or lorazepam) for catatonic schizophrenia.
Avoiding conventional antipsychotic drugs (they may worsen catatonic symptoms).
Investigating atypical antipsychotic drugs to treat catatonic schizophrenia (requires
further evaluation).
Nursing Interventions

DIAGNOSTIC TEST:
1. Clinical diagnosis is developed on historical information and thorough mental status
examination.
2. No laboratory findings have been identified that are diagnostic of schizophrenia.
3. Routine battery of laboratory test may be useful in ruling out possible organic etiologies,
including CBC, urinalysis, liver function tests, thyroid function test, RPR, HIV test, serum
ceruloplasmin ( rules out an inherited disease, wilson’s disease, in which the body
retains excessive amounts of copper), PET scan, CT scan, and MRI.

o Scale for the assessment of negative symptoms.
o Scale for the assessment of positive symptoms.
o Brief psychiatric rating scale
TREATMENTS AND MEDICATIONS:
Currently, there is no method for preventing schizophrenia and there is no cure.
Minimizing the impact of disease depends mainly on early diagnosis and, appropriate
pharmacological and psycho-social treatments. Hospitalization may be required to
stabilize ill persons during an acute episode. The need for hospitalization will depend on
the severity of the episode. Mild or moderate episodes may be appropriately addressed by
intense outpatient treatment. A person with schizophrenia should leave the hospital or
outpatient facility with a treatment plan that will minimize symptoms and maximize
quality of life.
A comprehensive treatment program can include:
Antipsychotic medication
Education & support, for both ill individuals and families
Social skills training
Rehabilitation to improve activities of daily living
Vocational and recreational support
Cognitive therapy
Medication is one of the cornerstones of treatment. Once the acute stage of a
psychotic episode has passed, most people with schizophrenia will need to take medicine
indefinitely. This is because vulnerability to psychosis doesn’t go away, even though
some or all of the symptoms do. In North America, atypical or second generation
antipsychotic medications are the most widely used. However, there are many first-
generation antipsychotic medications available that may still be prescribed. A doctor will
prescribe the medication that is the most effective for the ill individual
Another important part of treatment is psychosocial programs and initiatives. Combined
with medication, they can help ill individuals effectively manage their disorder. Talking
with your treatment team will ensure you are aware of all available programs and
medications.
In addition, persons living with schizophrenia may have access to or qualify for income
support programs/initiatives, supportive housing, and/or skills development programs,
