Schizophrenia and Psychotic Disorders/Symptoms



Schizophrenia and Psychotic Disorders/Symptoms





Schizophrenia is a thought disorder that includes psychotic symptoms such as delusions, hallucinations, and disordered thought processes. Psychotic behavior also can be encountered in clients who are experiencing other problems or disorders, such as bipolar disorder, alcohol withdrawal, or dementia. The care plans in this section address common psychotic symptoms, such as delusions and hallucinations, as well as problems and disorders that may produce psychotic symptoms, such as schizophrenia and certain medical conditions.

Schizophrenia

Schizophrenia is a disorder that involves characteristic psychotic symptoms (e.g., delusions, hallucinations, and disturbances in mood and thought) and impairment in the individual’s level of functioning in major life areas. The characteristic symptoms of schizophrenia (APA, 2000) are listed below. Clients typically experience symptoms in several of these areas.



  • Thought content. Delusional thoughts are fragmented, sometimes bizarre, and frequently unpleasant for the client. Many clients believe that their thoughts are “broadcast” to the external world, so others are able to hear them (thought broadcasting), that the thoughts are not their own but are placed there by others (thought insertion), and that thoughts are being removed from their head (thought withdrawal). The client believes all this thought control occurs against his or her will and feels powerless to stop it.


  • Perception. The major perceptual disturbance is hallucinations, most commonly auditory (voices). The voices may be familiar to the client and may command the client to do things that may be harmful to the client or others; there may be more than one voice “speaking” at once. Visual, tactile, gustatory, kinesthetic, and olfactory hallucinations also can occur, but less commonly.


  • Language and thought process. The client is unable to communicate meaningful information to others. There may be loose associations, or jumping from one topic to an unrelated topic. Poverty of speech or alogia (little verbalization), poverty of content (much verbalization but no substance), neologisms (invented words), perseveration (repetitive speech), clanging (rhyming speech), or blocking (inability to verbalize thoughts) may occur. The client may be unaware that others cannot comprehend what he or she is saying.


  • Psychomotor behavior. The client may respond excitedly to the environment, demonstrating agitated pacing or other movements, or may be almost unresponsive to the environment and exhibit motor retardation, posturing, or stereotyped movements. These disturbances are usually seen during acute psychotic episodes and in severely chronically ill clients.


  • Affect. The client has a restricted mood, may feel numb or lack the intensity of normal feelings, and demonstrates a flat or inappropriate affect. The client with a flat affect has a lack of expression, monotonous tone of voice, and immobile facies. (Note: Many psychotropic medications produce effects that resemble a flat affect.) An inappropriate affect occurs when the client’s expression is incongruent with the situation; for example, the client may talk of a sad event yet be laughing loudly.


  • Avolition. The client’s ability to engage in self-initiated, goal-directed activity is disturbed. This can persist into a residual phase, resulting in marked impairment in the client’s social, vocational, and personal functioning.

The symptoms of schizophrenia often are categorized as hard or soft signs. Hard signs include delusions and hallucinations, which are more amenable to the therapeutic effects of medication. Soft signs, such as lack of volition, impaired socialization, and affective disturbances, can persist after major symptoms of psychosis have abated and cause the client continued distress. The major types of schizophrenia and associated characteristics are as follows:



  • Catatonic: generalized motor inhibition, stupor, mutism, negativism, waxy flexibility, or excessive, sometimes violent motor activity


  • Disorganized: grossly inappropriate or flat affect, incoherence, loose associations, and extremely disorganized behavior



  • Paranoid: persecutory or grandiose delusions, hallucinations, sometimes excessive religiosity, or hostile, aggressive behavior


  • Undifferentiated: mixed schizophrenic symptoms along with disturbances of thought, affect, and behavior


  • Residual: symptoms are not currently psychotic, but the client has had at least one previous psychotic episode and currently has other symptoms, which may include social withdrawal, flat affect, or looseness of associations

Schizoaffective disorder is no longer categorized as a subtype of schizophrenia (APA, 2000). The symptoms are neither exclusively those of a major mood disorder nor of schizophrenia; rather, they are a combination of both.

Schizophrenia is equally prevalent in men and women; it affects approximately 1.1% of adults in the United States in a given year. The average age of onset is in the late teens or early twenties for men and the twenties or early thirties for women (National Institute of Mental Health, 2010). Schizophrenia is not diagnosed until relevant symptoms have been present for at least six months. Most clients continue to have symptoms that necessitate long-term management; these symptoms may wax and wane, be relatively stable, or progressively worsen over time (APA, 2000). The prognosis for a client with schizophrenia is better when onset is acute; a precipitating event is present; or the client has a history of good social, occupational, and sexual adjustment.

Interventions with clients with schizophrenia focus on safety, meeting the client’s basic needs, symptom management, medication management (see Appendix E: Defense Mechanisms), and long-term care planning. It is extremely important for the nurse to work closely with the interdisciplinary treatment team to coordinate acute care, referrals for continued care, and appropriate resources for support in the community.

Delusions

Delusions are false beliefs that are misperceptions or are not based in reality. Bizarre delusions “are clearly implausible and are not understandable and do not derive from ordinary life experiences” or represent a belief of “loss of control over mind or body” (APA, 2000, p. 299). Nonbizarre delusions are beliefs that are false in the present situation but could possibly happen in other circumstances.

The client may have delusional ideas in more than one area or may have insight into the delusional state but is unable to alter it. Sometimes the delusion is the antithesis of what the client thinks or feels. For example, a client who feels unimportant may believe himself or herself to be Jesus Christ, or a client who is destitute may believe himself or herself to be a wealthy financier.

Delusions can occur as one of several symptoms as in schizophrenia or bipolar disorder, or the primary symptom, as in a delusional disorder. Common categories of delusions are persecutory, grandiose, somatic, religious, poverty or wealth, contamination, and infidelity.
