Paranoid people avoid relationships in which they aren’t in control or have the potential of losing control. Contributing factors • Genetic predisposition • Neurochemical alteration • Parental antagonism Assessment findings • Feelings of being deceived • Suspiciousness, mistrust of friends and relatives • Refusal to confide in others • Hostility • Emotional reactions, including nervousness, jealousy, anger, or envy • Self – righteousness • Social isolation • Sullen attitude • Lack of social support systems • Hyperactivity, especially in children • Delusional thinking • Hypervigilance • Lack of humor • Major distortions of reality • Need to be in control Diagnostic evaluation There are no specific tests for paranoid personality disorder. Nursing diagnoses Anxiety Ineffective individual coping Chronic low self – esteem Social isolation SCHIZOPHRENIC AND DELUSIONAL DISORDERS People with major distortions in ego functioning experience serious disturbance in all areas of their lives, having impaired reality testing and a compromised ability to relate with others. Common signs of impairment in reality testing include bizarre behaviors, inability to assume responsibility for oneself, and misinterpretation of environmental stimuli.
  3. 3. Major disturbances in ego functioning can result from functional causes, such as acute psychosis, or from underlying organic causes related to drug ingestion, high fever, an accumulation of toxins in the body, or dementia. SCHIZOPHRENIA is a brain disease characterized by nueurotransmitter imbalances and structural changes within the brain. Distorted though processes make living with this disease a challenge. Symptoms from schizophrenia may be characterized a positive or negative. Positive symptoms focus on a distortion of normal functions; negative symptoms focus on a loss of normal functions. Overview A. Characterized by disordered thinking, delusions, hallucinations, depersonalization (feelings of being strange, not oneself), impaired reality testing (psychosis), and impaired interpersonal relationships. B. Regression to the earliest stages of development is often noted (e.g., incontinence, mutism) C. Onset is usually in adolescence/early adulthood. D. Client may be seriously impaired and unable to perform ADL. E. Etiology is not known; theories include 1. Genetic: 1% of population; risk approximately 15% with one schizophrenic parent, approximately 30% with two. 2. Family; double – bind communication; message sent in negated. 3. Biochemical; increased dopamine activation. 4. Interaction of predisposing risk and environmental stress. 5. Psychoanalytic; fragile ego resorts to dysfunctional use of defense mechanisms (e.g., identification, projection). F. Prior to onset (premorbid) client may have been suspicious, eccentric, or withdrawn. Classifications A. Disorganized: incoherent; delusions are not organized; social withdrawal; affect blunted, silly or inappropriate B. Catatonic: psychomotor disturbances 1. Stupor: mute, little reaction or movement 2.

After a hallucination, the client may be exhausted. Be sure to allow time for the client to rest or sleep. BEHAVIORS AND SENSATION TRUSTING INTERVENTIONS The client feels anxious or lonely and attempts to cope by daydreaming or seeking out a trusted person. • Lack of structure and feelings of loneliness may precipitate hallucinations. Therefore, provide the client with a highly structured daily routine and engage the client in a structured activity to dissipate anxiety and feelings of loneliness. • Don’t allow the client hours of free time. The client experiences increasing anxiety, which leads to a state of alertness. The client becomes preoccupied with internal sensations (such as voices and images) and starts to respond to them. Aware that the sensations are internal, the client attempts to control them. • Help the client compare internal sensations with external reality. • Engage the client in a structured activity. • Teach the client to hum, whistle, or talk but loud to “crowd out” internal sensations. • Ask the client to identify concrete things in the external environment. As internal sensations become increasingly dominant, the client has trouble controlling them and eventually yields to them. • Talk to the client about external reality. • Ask the client to compare the hallucination with external reality. • Use self as a focal point to get the client’s attention and the client to focus on what you’re doing and saying. • Instruct the client to firmly tell the hallucination to go away. • Engage the client in a large – muscle activity. The client becomes immersed in internal sensations and feels powerless over them. Depending on the nature of the hallucination, the client may become very frightened. • Have the client focus on external reality. • Do whatever is necessary to get the client’s attention. • Maintain a firm but kindly tone of voice.
  8. 8. Delusional disorder A delusion is a false belief to which a person adheres despite contradictory evidence. Clients with DELUSIONAL DISORDER hold firmly to false beliefs despite contradictory information. The client with delusional disorder tends to be intelligent and can have a high level of competence but has impaired social and personal relationships. One indication of delusional disorder is an absence of hallucination. The most common types of delusions include: • Delusions of grandeur – belief that one is highly important, famous, or powerful • Delusions of persecution – belief that one is being persecuted or harmed by others. • Delusions of reference – belief that one is connected to events unrelated to himself. Planning and goals • The client won’t harm self or others. • The client will learn alternative coping strategies. • The client will regain normal level of functioning. Implementation • Formulate realistic, modest goals with the client to help diminish suspicion while increasing the client’s self – esteem and sense of control. • Establish a therapeutic relationship to foster trust. • Explore event that trigger delusions to help you understand the dynamics of the client’s delusional system. Discuss anxiety associated with triggering events. • Don’t directly attack the delusion to avoid increasing the client’s anxiety instead, be patient in formulating a trusting relationship. • Once the dynamics of the delusions are understood, discourage repetitious talk about delusions and refocus the conversation on the client’s underlying feelings. As the client identifies and explores feelings, he’ll decrease reliance on delusional thought. • Recognize delusion as the client’s perception of the environment. Avoid getting into arguments with the client regarding the content of delusions to foster trust. • Teach the client alternative coping mechanisms to handle periods of increased anxiety and enhance the client’s self – esteem and self – control. • Review key teaching topics with the client and family members to ensure adequate knowledge about the condition and treatment, including: o Learning decision – making, problem – solving, and negotiating skills. o Understanding potential adverse effects of medication. Evaluation • The client doesn’t harm self or others. • The client demonstrates less suspicious behavior. • The client can identify signs and symptoms of anxiety. • The client identifies factors that precipitate delusions and alternative coping mechanism to handle anxiety.
