Study Notes

Overview of Schizophrenia

Schizophrenia is a neurobiological disorder characterized by psychotic symptoms, social difficulties, and atypical behaviors.
Onset commonly occurs in early adulthood but can begin in childhood, adolescence, or later.
Chronic aspects significantly impair communication, cognition, memory, emotional regulation, and social interactions.
Life expectancy may be reduced due to comorbid conditions and heightened suicide risk.
Stigmatization presents a major challenge for individuals affected by schizophrenia.

Pathophysiology

Complex mechanisms include structural brain changes, neurotransmitter abnormalities, and immune system impairments.
Structural abnormalities often feature reduced gray matter in the prefrontal cortex, temporal lobes, hippocampus, thalamus, enlarged ventricles, and decreased blood flow.
Noticeable brain changes may intensify with episodes of psychosis.

Neurotransmitter Abnormalities

Dopaminergic system disturbances are central, with antipsychotics targeting D2 dopamine receptors.
GABA and acetylcholine system disruptions, including reduced nicotinic receptors, contribute to symptoms.
Glutamate system dysregulation, involving NMDA receptor abnormalities and reduced glutamate levels in cerebrospinal fluid (CSF), impacts dopamine processing.

Epigenetic factors are significant, including birth complications and substance use.

Safety Alert

High suicide risk necessitates close monitoring for individuals with schizophrenia.
Key risk factors include heightened illness awareness, young age, recent loss, inadequate support, and prior treatment failure.

Prevention and Rehabilitation

Early cognitive, developmental, and behavioral screening leads to improved outcomes.
Antipsychotic treatment for prodromal symptoms raises ethical concerns as not all may progress to schizophrenia.
Recovery focuses on symptom management, treatment adherence, stress reduction, and preventing relapse.
Rehabilitation aims for wellness that enables engagement in goal-directed activities.

Clinical Manifestations

Symptoms may fluctuate in periods of exacerbation and remission, affecting daily living.
Categories include positive, negative, cognitive, and affective symptoms.

Symptom Types

Positive Symptoms: Hallucinations (often auditory), delusions (false beliefs), and disorganized thinking (speech disruptions).
Negative Symptoms: Flat affect, thought blocking, and alogia (reduced speech).

Treatment Approaches

Dopamine-System Stabilizers (DSSs): Target both dopamine and serotonin receptors; typically have fewer side effects.
Use of adjunctive medications like antianxiety agents, antidepressants, and mood stabilizers is common.
Adherence technology like Abilify MyCite incorporates an ingestible sensor for tracking medication adherence.

Planning: Goals aimed at reducing symptoms, enhancing quality of life, and achieving personal objectives.
Implementation: Ensures a safe environment, medication management, monitoring for suicidal behaviors, and providing symptomatic treatments.

Cytokines and Schizophrenia

Elevated cytokine levels are observed during acute psychosis or relapse.

Etiology of Schizophrenia

Causes remain unclear but involve genetic, environmental, and epigenetic factors.
Genetic predisposition: Polygenic risk increases with a family history of schizophrenia.
Paternal age: Older fathers have a higher risk due to potential sperm mutations.
Maternal age: Advanced maternal age is also associated with increased risk.
Environmental influences include prenatal health and infections like Toxoplasma gondii.

Risk Factors for Schizophrenia

High suicide risk in individuals with schizophrenia necessitates close monitoring.
Factors elevating suicide risk: Awareness of illness, younger age, recent losses, limited support, recent discharge from care, and treatment failures.
Early life adversities, such as poverty, violence, and trauma, contribute to risk.
Children and adolescents showing developmental issues are at a higher risk.
Stressors in early childhood or adolescence may also heighten risk.

Prevention and Early Detection

Early screening for cognitive and behavioral changes can improve outcomes.
Secondary prevention strategies raise ethical concerns regarding premature treatment initiation.
Health promotion focuses on recovery, treatment adherence, stress management, and relapse prevention.

Clinical Manifestations of Schizophrenia

Hallucinations: False sensory experiences, often auditory.
Delusions: Strongly held false beliefs, varying in nature (e.g., grandiose, persecutory).
Motor Symptoms: Includes catatonia and psychomotor abnormalities.
Disorganized Thinking: Impaired speech and thought processes, e.g., tangentiality, incoherence.

Negative Symptoms

Flat or blunted affect: Reduced emotional responsiveness.
Thought blocking: Sudden halts in conversation.
Alogia: Limited speech and thought.
Anhedonia: Reduced pleasure in activities.
Avolition: Lack of motivation to initiate activities.
Social withdrawal: Avoidance of social interaction.

Cognitive Symptoms

Memory deficits: Impaired verbal and visual memory.
Attention difficulties: Struggles with focus and filtering distractions.
Facial recognition issues: Difficulty recognizing familiar faces.
Executive functioning deficits: Challenges in planning and organization.

Affective Symptoms

Depression and mania: Increased suicide risk, particularly in conjunction with other factors.

Residual Phase: Stabilization post-acute phase, with possible persistent symptoms.

Comorbid Disorders

Increased likelihood of cardiovascular disease, diabetes, and respiratory illnesses.
Common substance abuse issues include alcohol, cannabis, and opioids.
Higher rates of depression and anxiety disorders, alongside PTSD in some individuals.

Diagnosis and Testing

Diagnosis involves psychiatric evaluation and must meet DSM-5 criteria.
Significant impairment over six months; other disorders must be excluded.

Pharmacologic Therapy

Antipsychotics are the primary treatment, effective in managing positive symptoms.
Adherence to medication is vital due to high relapse risk upon discontinuation.
Potential life-threatening risks include elevated suicide risk and severe side effects, particularly for older adults.

Types of Antipsychotics

Typical Antipsychotics: Block D2 receptors; side effects include anticholinergic effects and extrapyramidal symptoms.
Atypical Antipsychotics: Block D2 and serotonin receptors; have fewer extrapyramidal effects but may cause metabolic syndrome.

Late-Onset and Very-Late-Onset Schizophrenia

Late-Onset Schizophrenia (LOS): Occurs after age 40, commonly in women; symptoms are less severe.
Very-Late-Onset Schizophrenia (VLOS): Develops after age 60; managed with lower doses and psychosocial interventions.

Nursing Process

Assessment: Includes observation, health history, physical exam, and mental status evaluation.
Diagnosis: Focuses on managing risks and enhancing communication skills.
Planning: Goals center on symptom reduction and improving overall quality of life.
Implementation: Ensures safety, provides symptomatic treatment, and checks treatment adherence.

Overview of Schizophrenia

Schizophrenia is a severe neurobiological disorder characterized by psychotic symptoms, impaired social interactions, and atypical behaviors.
Onset typically occurs in early adulthood, though it can manifest in childhood, adolescence, or later life.
Chronic features lead to significant functional deficits impacting communication, cognition, attention, memory, emotional regulation, and social interactions.
Associated with reduced life expectancy due to comorbidities and high suicide rates.
Stigmatization poses significant challenges for individuals affected by the disorder.

Pathophysiology

Involves complex mechanisms including structural brain alterations, neurotransmitter dysfunctions, and immune system impairments.
Structural abnormalities consist of reduced gray matter volume in the prefrontal cortex, temporal lobes, hippocampus, thalamus, enlarged ventricles, and decreased cerebral blood flow.
Episodes of psychotic symptoms can amplify the visibility of these brain changes.

Neurotransmitter Abnormalities

Dopaminergic System: Antipsychotic medications focus on D2 receptor modulation.
GABA and Acetylcholine: Reduced nicotinic acetylcholine receptors in the hippocampus contribute to symptoms.
Glutamate: Dysregulated NMDA receptors and low glutamate levels in cerebrospinal fluid (CSF) disrupt dopamine activity and prefrontal processing.

Immunologic and Inflammatory Pathways

Activated microglia produce cytokines that potentially impair NMDA receptor function and dopamine regulation.

Diagnostic Tests

Schizophrenia diagnosis involves psychiatric evaluation, history taking, and potentially screening tools.
Must fulfill DSM-5 criteria with significant impairment lasting six months or more, excluding other mental disorders and substance use.

Pharmacologic Therapy

Antipsychotics: Core treatment aimed at alleviating positive symptoms like hallucinations and delusions, without curing the disorder.
Medication adherence is critical; discontinuation raises relapse risk. Challenges include denial, self-care deficits, and side effects.
Risks: Increased suicidal risks and severe health complications, especially in the elderly with dementia. Atypical antipsychotics carry a black box warning for dementia-related psychosis.

Types of Antipsychotics

Typical Antipsychotics: Block postsynaptic D2 receptors. Adverse effects include anticholinergic symptoms, sexual dysfunction, endocrine issues, and extrapyramidal symptoms (EPS).
Atypical Antipsychotics: Block both D2 and serotonin receptors. They have lower rates of EPS and tardive dyskinesia (TD) but can lead to metabolic syndrome and diabetes.
Dopamine-System Stabilizers (DSSs): Target dopamine and serotonin receptors, generally well tolerated and can address depressive symptoms, used as adjunct therapy.

Adjunctive Medications

Patients may receive antianxiety agents, antidepressants, and mood stabilizers as supplementary treatments.

Adherence Technology

Aripiprazole (Abilify MyCite) incorporates an ingestible sensor, monitoring medication adherence through a smartphone app.

Nonpharmacologic Therapy

Emphasizes personalized recovery models, integrating diverse resources to aid individual goals and strengths.
Collaborative approach with various health professionals is essential.

Family Intervention and Psychoeducation

Family engagement through psychoeducation reduces relapse rates and enhances family dynamics.
Extended interventions combined with pharmacologic treatments yield optimal outcomes.

Aids in improving interpersonal capabilities through structured methods like Social Cognition and Interaction Training (SCIT).

Cognitive-Behavioral Therapy (CBT)

Employs strategies for symptom coping, including distraction and positive self-talk, though its effectiveness may vary.

Cognitive Remediation

Targets cognitive deficits with compensatory techniques and practice to enhance cognitive functions.

Vocational Training

Aims to improve employability and functional capacity, including supported employment programs for job maintenance.

Community Service Models

Crisis Intervention: Provides short-term, intensive care for severe symptoms.
Case Management: Coordinates care through dedicated professionals.
Assertive Community Treatment (ACT): Offers comprehensive, continuous care with 24/7 availability.

Electroconvulsive Therapy (ECT)

Considered for severe, treatment-resistant schizophrenia, particularly with depressive or catatonic features, most effective alongside medication.

Repetitive Transcranial Magnetic Stimulation (rTMS)

FDA-approved for depression; emerging evidence suggests it may alleviate auditory hallucinations in schizophrenia.

Complementary Health Approaches

Nutritional interventions and mind-body practices have limited efficacy as primary treatment methods. Omega-3 fatty acids show potential but require further research.

Lifespan Considerations

Onset typically occurs in early adulthood while Early-Onset Schizophrenia (EOS) occurs before age 18, and Late-Onset Schizophrenia (LOS) after age 40, requiring distinct management strategies.

Late-Onset and Very-Late-Onset Schizophrenia

LOS: Onset after age 40, more common in females, characterized by paranoia and hallucinations, often requiring lower antipsychotic doses.
VLOS: Begins after age 60, linked to neurodegeneration and potentially sociocultural factors, managed with lower-dose antipsychotics and psychosocial support.

Nursing Process

Assessment: Focuses on physical, mental, and health history evaluations.
Diagnosis: Common needs involve managing self-care deficits and improving communication skills.
Planning: Goals prioritize symptom management and enhancing quality of life.
Implementation: Emphasizes injury prevention, medication management, and symptomatic treatment adjustments.
