Chapter 15: Psychotic Disorders

Psychotic disorders (including schizophrenia) affect:

• Thinking

• Behavior

• Emotions

• Ability to perceive reality

Etiology (Causes)

• Likely due to a combination of:

  • Genetic factors

  • Neurobiological factors

  • Nongenetic factors (injury at birth, viral infection, nutritional factors)

Onset

• Typical age: mid-teens to mid-20s

• Can occur:

  • In young children

  • In later adulthood

Prodromal Period

• Early stage before full disorder develops

• Symptoms may include:

  • Negative symptoms (e.g., anergia = lack of energy)

  • Reduced positive symptoms (less intense hallucinations/delusions)

Impact

Alterations in Thought (Delusions)

False, fixed beliefs that cannot be corrected by reasoning (often bizarre).

Boundary impairment – inability to see distinction between self and others

Personality Disorder Standardized Screening Tool: AIMS (Abnormal Involuntary Movement Scale)

Monitors involuntary movements and tardive dyskinesia in clients on antipsychotic medications

Personality Disorder Nursing Care

Therapeutic Approaches

• Milieu therapy – structured, safe environment to reduce anxiety & distraction from hallucinations

• Assertive Community Treatment (ACT) – intensive case management & interprofessional support for community-living needs

• Promote therapeutic communication – reduces anxiety, defensive patterns, and increases participation

• Establish trusting relationship with client

Communication for Hallucinations & Delusions

• Ask directly about hallucinations (acknowledge feelings without agreeing/disagreeing)

• Do not argue with delusions; instead, focus on client’s feelings and provide supportive responses

• Monitor for paranoid delusions (risk for violence)

• Ensure safety if client has command hallucinations (↑ risk for harm to self/others)

• Use reality-based topics in conversation

• Identify manifestation triggers (e.g., loud noises can worsen auditory hallucinations)

• Be genuine and empathetic

Additional Nursing Interventions

• Determine discharge needs (ADLs, ability to live independently)

• Promote self-care by teaching/modeling within facility

• Link wellness to manifestation management

• Teach coping strategies for hallucinations/anxiety:

  • Music, attending activities, walking, talking with trusted person, directly addressing hallucination (“go away”)

• Provide medication education

• Involve family when possible

---

Client Education

• Develop social skills and friendships

• Participate in group work and psychoeducation

• Comply with medications

​​​​​​​A nurse is speaking with a client who has schizophrenia when the client suddenly seems to stop focusing on the nurse’s questions and begins looking at the ceiling and talking to themselves. Which of the following actions should the nurse take?

a

​​​​​​​Stop the interview at this point, and resume later when the client is better able to concentrate.

b

Ask the client, “Are you seeing something on the ceiling?”

c

Tell the client, “You seem to be looking at something on the ceiling. I see something there, too.”​​​​​​​ 

d

Continue the interview without commenting on the client’s behavior.

Submit

b Ask the client, “Are you seeing something on the ceiling?”

When taking action, the nurse should ask the client directly about the hallucination to identify client needs and monitor for a potential risk for injury.

---

The nurse should address the client’s current needs related to the possible hallucination rather than to stop the interview.

Avoid agreeing with the client, which can promote psychotic thinking

The nurse should address the client’s current needs related to the possible hallucinations rather than ignoring the change in behavior.

1st vs 2nd vs 3rd Gen Atypical Antipsychotics

Primarily blocks dopamine (D2) receptors

No effect on NT systems (only treats positive symptoms)

Side Effects: Neuroendocrine, Neuroleptic Malignant Syndrome (NMS)

anti-HAM (histamine-1, alpha-1, muscarinic-1 inhibitors)

---

Primarily blocks dopamine (D2) and serotonin (5HT2A) receptors

Treats positive and negative symptoms

Side Effects: Metabolic Syndrome, Elevated Prolactin

---

Primarily PARTIALLY BLOCKS (partial agonist) dopamine (D2) (stabilizes levels) and block serotonin (5HT2A) receptors

Treats positive and negative symptoms

Side Effects: Metabolic Syndrome, Elevated Prolactin

anti-HAM (histamine-1, alpha-1, muscarinic-1 inhibitors) and anti-D2

• wt gain, sedation, orthostasis, hypotension, priapism, dryness

• high eps, high nms

1st Gen Antipsychotics

Blocks D2 + 5HT2a (serotonin)

• hotspot for less eps and no nms

• BUT metabolic syndrome (glucose inolerence), hyperprolactinemia

2nd Gen Antipsychotics

What do all antipsychotics do?

DECREASE DOPAMINE

• Improves positive symptoms

• Stabilizes or worsens negative symptoms

What lead theory explains causes positive vs negative symptoms?

Mesolimbic (brain reward) pathway → TOO MUCH DOPAMINE

• DA OVERACTIVITY from Ventral Tegmental Area (VTA) → Nucleus Accumbens (NA)

  • Tx: DA decreased by 1st-3rd Gen Antipsychotics

---

Mesocortical (thinking/emotion) pathway → TOO LITTLE DOPAMINE

• DA UNDERACTIVITY from Ventral Tegmental Area (VTA) → CORTEX

  • Tx: DA stabilized by 2nd-3rd Gen Antipsychotics but ultimately all decrease DA

What lead theory explains why EPS/Parkinson symptoms develop from antipsychotics?

Nigrostriatal pathway (does not cause schizophrenia or symptoms)

• DA from Substantia Nigra (SN) → Striatum (Caudate+Putamen)

  • LOW(ered) DA = EPS such as Parkinson’s symptoms

    • Mask, rigidity, shuffling

What lead theory explains why Prolactin increases antipsychotic meds?

Tuberoinfundibular Pathway

• DA from Hypothalamus (HT) → Pituitary Gland (PG) → Prolactin (PL)

  • LOW(ered) DA = HIGH PROLACTIN (vice versa)

    • S/S = amenorrhea (reduced FSH) + galactorrhea

Antipsychotics: Second- and Third-Generation (Atypical) (-apine, idone, -ipra-) Action / Use

Second-gen: Block serotonin (main) and dopamine (lesser degree) receptors

Third-gen: Stabilize dopamine system as agonist + antagonist (partial agonist)

Both block norepinephrine, histamine, acetylcholine receptors

K = monitor increased K+, cK (creatine kinase), Killer cells (rhabdomyolysis)

D = D/C antipsychotic, Dantrolene, Dopamine agonist

Anticholinergics

Block the muscarinic receptors

• Assists dopamine and acetylcholine receptor balance in the brain (basal ganglia)

  • Treats drug-induced parkinsonism or dystonia (acute) of EPS (PD needs A)

  • Can quickly reduce muscle rigidity and spasms.

• (e.g., benztropine, trihexyphenidyl, diphenhydramine) are often used to treat or prevent EPS.

Less effective for akathisia

Not recommended for tardive dyskinesia (can worsen it).

---

Side Effects

• Central effects: confusion, memory impairment (especially in older adults)

• Peripheral effects: dry mouth, blurred vision, constipation, urinary retention, tachycardia
  Thus, clinicians must balance EPS relief with risk of anticholinergic toxicity.

Centrally acting anticholinergics antagonists

Reduces [] effect (neuron excitability) due to decreased dopamine

• Quickly reduce muscle rigidity and spasms.
