Impact of Schizophrenia

• Schizophrenia leads to:
  • Lengthy hospitalizations.
  • Chaotic family life.
  • High costs to individuals and government.
  • Associated fear within communities.
• Early diagnosis is rare; most people do not go undiagnosed.

Phases of Schizophrenia

1. Morbid Phase

   • Characterized by:
     • Shyness and social withdrawal.
     • Poor relational skills.
     • Academic challenges.
     • Possible antisocial behavior.

2. Prodromal Phase

     • Significant deterioration in functioning.
     • Social withdrawal.
     • Depressed mood.
     • Poor concentration and fatigue.
     • Possible sudden onset of obsessive-compulsive behavior.
     • Patients may exhibit a disheveled appearance.
     • Prognosis may correlate with previous behavior patterns.

3. Active Phase

   • Defined by the emergence of psychotic symptoms.

4. Residual Phase

   • The aftermath of the active phase with reduced symptoms but ongoing challenges.

Prognosis Factors

• Positive prognosis indicators:
  • Later onset of disorder.
  • Female gender.
  • Abrupt onset due to stress.
  • Associated mood disturbances.
  • Brief active phase symptoms.
  • Minimal residual symptoms.
  • Absence of structural brain abnormalities.
  • Normal neurological function.
  • No family history of schizophrenia.

Biochemical and Physiological Triggers

Predisposing Factors

• Biochemical Factors:

  • Hypothesis: Excessive dopamine activity may cause schizophrenia.
  • Abnormalities in various neurotransmitters are also implicated.

• Physiological Triggers:

  • Viral infections, birth trauma, head injuries, alcohol abuse, and brain tumors.

Social and Environmental Factors

• Poverty and stressful life events can exacerbate symptoms and trigger relapses.

Genetic Vulnerability

• Certain genes linked to increased risk of schizophrenia.
• Adolescent cannabis use correlates with higher psychosis risk.

Types of Schizophrenia and Other Psychotic Disorders

1. Brief Psychotic Disorder: Sudden onset of symptoms, possibly after severe stress.
2. Grandiose Type: Characterized by delusions of being persecuted or grandeur.
3. Substance-Induced Psychotic Disorder: Symptoms directly tied to substance use.
4. Catatonic Disorder: Symptoms attributable to a medical condition; includes nonresponsiveness and flat affect.
5. Schizophreniform Disorder: Symptoms match schizophrenia, but duration is 1 month to less than 6 months.
6. Schizoaffective Disorder: Includes mood disorder symptoms alongside schizophrenia symptoms.

Positive Symptoms of Schizophrenia

• Avolition: Lack of motivation for goal-directed activities.
• Impaired Personal Grooming: Poor self-care habits.
• Impaired Interpersonal Functioning: Difficulty in social relationships.

Common Psychiatric Diagnoses

1. Disturbed Sensory Perception: Related to anxiety and withdrawal.
2. Disturbed Thought Processes: Related to distrust and possible hereditary factors.
3. Social Isolation: Associated with delusional thinking and regression.
4. Risk for Violence: Due to panic and extreme suspiciousness.
5. Impaired Verbal Communication: Linked to anxiety and unrealistic thinking.
6. Self-Care Deficit: Related to perceptual and cognitive impairments.

Treatment Goals/Outcomes

• Patients should:
  • Relate satisfactorily to others.
  • Recognize and manage their distortions of reality.
  • Not harm themselves or others.
  • Perceive themselves and their environment realistically.
  • Maintain a manageable anxiety level.

Treatment Modalities

• Psychological Treatments:
  • Individual psychotherapy for long-term therapeutic engagement.

• Social Skills Training:
  • Role play for developing interpersonal skills.
• Family Therapy:

• Community Support Programs:
  • Assertive community treatment for consistent outpatient support.

Pharmacological Treatments

• Antipsychotics:

  • Common side effects include:
  • Anticholinergic effects (e.g., dry mouth).
  • Extrapyramidal symptoms (e.g., resembling Parkinson's disease).
  • Weight gain, sedation, and potential for diabetes, seizures, or agranulocytosis.
  • Important patient education about side effects and what to report to healthcare providers.

Patient and Family Education**

• Understand the illness and progression.
• Recognize connections between stress and symptoms.
• Medication management and adherence.
• Avoiding substances that could exacerbate symptoms.
• Techniques for managing anxiety, such as breathing exercises or using a rubber band for distraction.

Support Services

• Consideration of home health plans for patient assistance.
• Providing resources for daycare facilities for family caregivers.

NCLEX Preparation

• Emphasize the need for continuous evaluation and monitoring in care plans for schizophrenia treatment.
