Expert Answer

Comparison of Delirium and Brief Psychotic Disorder:

Delirium and Brief Psychotic Disorder are both psychiatric conditions that can present with symptoms affecting cognition, perception, and behavior, but they differ significantly in their causes, course, and treatment. Understanding these differences, particularly in adult and geriatric populations, is crucial for the psychiatric mental health nurse practitioner (PMHNP) to make an accurate diagnosis.

Delirium:

Definition and Key Features:
Delirium is an acute confusional state that affects attention, cognition, and awareness. It is a neurocognitive disorder characterized by a sudden onset of confusion and disorientation, often fluctuating throughout the day. Delirium typically occurs in response to a medical condition, such as an infection, metabolic imbalance, drug toxicity, or withdrawal, especially in older adults.

Key symptoms include:

• Disturbance in attention and awareness: Patients may be unable to focus, sustain, or shift attention.
• Cognitive impairment: This includes memory deficits, disorientation, and difficulty with language or perception.
• Fluctuating course: Symptoms tend to worsen at night (known as “sundowning”).
• Hyperactive, hypoactive, or mixed motor behavior: Patients may be agitated or lethargic.

Etiology and Risk Factors:
Delirium is typically caused by underlying medical conditions such as infections (e.g., urinary tract infections, pneumonia), metabolic disturbances (e.g., hyponatremia), drug toxicity, dehydration, or post-surgical states. It is more common in older adults, especially those with dementia, chronic illness, or polypharmacy.

Course and Prognosis:
Delirium tends to have a rapid onset (often hours to days) and fluctuates throughout the day, often resolving once the underlying cause is addressed. However, untreated delirium can lead to poor outcomes, such as delirium superimposed on dementia or even long-term cognitive decline.

Brief Psychotic Disorder:

Definition and Key Features:
Brief Psychotic Disorder is a psychotic disorder characterized by the sudden onset of psychotic symptoms such as delusions, hallucinations, disorganized speech, or disorganized behavior. The symptoms last at least one day but less than one month, and the individual eventually returns to their baseline functioning. Brief Psychotic Disorder is not attributed to a medical condition or substance use but may arise in response to a significant stressor.

Key symptoms include:

• Delusions: Fixed false beliefs not grounded in reality.
• Hallucinations: Sensory experiences (e.g., auditory, visual) that are not real.
• Disorganized speech and behavior: Incoherent speech, nonsensical ideas, or unusual behavior.
• Emotional blunting or inappropriate emotional reactions can occur.
