Psychosis in late life: emerging issues

Area of Science:

• Geriatric Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Psychotic symptoms are increasingly recognized in older populations.
• While many psychoses mirror those in younger individuals, late-onset presentations have distinct clinical features.
• Chronic conditions like dementia and schizophrenia, alongside acute disorders like delirium, can manifest with psychosis in seniors.

Purpose of the Study:

• To explore the prevalence and characteristics of psychosis in older adults.
• To differentiate between early-onset and late-onset psychosis.
• To review the presentation and management of psychosis within chronic disorders affecting the elderly.

Main Methods:

• Literature review focusing on chronic psychotic disorders in older individuals.
• Analysis of clinical presentations of various late-onset psychoses.
• Discussion of treatment strategies for psychosis in elderly patients with dementia and schizophrenia.

Main Results:

• Psychosis in older adults can stem from chronic conditions (dementia, schizophrenia, delusional disorder) or acute states (delirium, substance-induced).
• Key differences exist between early-onset and late-onset psychosis.
• Focus is placed on chronic disorders, including schizophrenia (early-onset and late-onset), very late-onset schizophrenia-like psychosis, delusional disorder, and Alzheimer's disease.

Conclusions:

• Psychosis in older adults is a significant clinical concern, often linked to chronic neurodegenerative and psychiatric conditions.
• Understanding the nuances of late-onset psychosis is crucial for accurate diagnosis and effective treatment.
• This review provides insights into managing psychosis in elderly patients with conditions like dementia and schizophrenia.
