Summary: A new interdisciplinary report offers a practical, urgent framework for recognizing and responding to Alzheimer’s-related psychosis (ARP), a damaging and often underappreciated complication of Alzheimer’s disease. The guidance emphasizes person-centered care, prioritizes nonpharmacologic approaches, and lays out cautious, limited circumstances for medication use given serious safety concerns.
Drawing on clinical experience and recent evidence, the panel documents how delusions and visual hallucinations in people with Alzheimer’s can rapidly worsen cognitive decline, increase emergency hospitalizations, and force earlier placement in long-term care. The Gerontological Society of America (GSA) coalition highlights that, with no medications currently approved specifically for ARP, clinicians and caregivers need clear procedures that reduce harm while preserving dignity and safety.
The proposed model places early emphasis on behavioral mapping and environmental adjustments to identify and remove triggers for psychotic symptoms. It also warns that commonly used off-label antipsychotic medications carry a federally boxed warning about increased mortality in older adults with dementia, so their use must be tightly restricted, short-term, and carefully monitored.
Key Facts
- The scope of neuropsychiatric distress: Alzheimer’s disease affects more than seven million people in the United States and accounts for roughly 60–80% of dementia cases. Psychosis—manifested as delusions or hallucinations—can appear at any stage and often destabilizes a person’s sense of reality.
- The clinical fallout cascade: The onset of ARP often marks a turning point in a patient’s clinical course. It is associated with faster cognitive decline, more frequent emergency room use, greater caregiver stress and burnout, and earlier transitions to institutional long-term care.
- Prioritizing triggers over sedation: Experts, including Kalisha Bonds Johnson, PhD, RN, PMHNP-BC, emphasize training caregivers and clinical staff to document behavioral triggers, adjust lighting and sensory inputs, and use emotional redirection. These nonpharmacologic strategies should be the first-line response, reducing reliance on chemical restraints.
- The dangerous off-label paradox: Antipsychotics are often prescribed off-label to manage severe hallucinations and delusions, yet clinical data link these drugs to higher mortality among older adults with dementia. The report counsels a conservative approach: start at the lowest effective dose, use brief courses when necessary, and taper as soon as clinically feasible.
- Severity and persistence guide treatment: As Clifford Singer, MD, notes, medications should be considered only when psychotic symptoms are severe, persistent, and cause significant distress or immediate safety concerns. Nonthreatening or peaceful illusions are often best managed without pharmacologic intervention.
- Supporting caregivers: Delusions frequently involve accusatory or distressing interpretations directed at family members. The report recommends targeted caregiver counseling to teach de-escalation, reassurance, and redirection techniques that preserve relationships and enable continued home care where possible.
- Investigational treatments: The report highlights ongoing clinical research into novel targeted compounds designed specifically to treat ARP. These investigational therapies hold promise for filling the current therapeutic gap, but they remain under study.

“Alzheimer’s-Related Psychosis: Interdisciplinary Perspectives for Understanding and Responding to Delusions and Hallucinations”—the latest issue in The Gerontological Society of America’s Insights & Implications in Gerontology series—summarizes how psychosis affects people living with Alzheimer’s disease and their families and why a comprehensive, person-centered approach is essential.
Alzheimer’s-related psychosis includes a range of symptoms, from fixed false beliefs to vivid visual hallucinations, that may emerge at any time during the disease. These symptoms often accelerate functional decline and create new safety challenges, increasing the need for coordinated care strategies that span home, outpatient, and institutional settings.
“Psychosis in Alzheimer’s disease is both common and complex, yet frequently underrecognized,” said Kalisha Bonds Johnson of Emory University, a faculty member on the report team. “These symptoms can dramatically affect quality of life for both the person with Alzheimer’s and their caregivers, making early identification and thoughtful management essential.”
The report recommends an initial emphasis on nonpharmacologic interventions: structured behavioral assessments to identify triggers, adjustments to lighting and sound, consistent daily routines, and staff training in de-escalation and redirection techniques. These interventions aim to reduce distress without immediately resorting to medication.
When behavioral measures are insufficient and the person is at risk of harm or experiencing severe distress, clinicians can consider pharmacologic options. Given the lack of approved treatments specifically for ARP and the safety concerns associated with antipsychotics in older adults with dementia, any medication must be used judiciously—with careful dosing, clear goals, and frequent reassessment.
“We consider persistence, severity, and distress when determining how to manage symptoms,” said Clifford Singer, MD, of Northern Light Acadia Hospital. “Medications can be effective when used appropriately, but they come with risks and must be carefully managed.”
Caregiver education and support are integral to effective management. The report underscores techniques for caregivers—such as validating feelings rather than arguing about hallucinated content, offering calm reassurance, and redirecting attention—that can de-escalate frightening experiences without the harms associated with sedative medications.
The document also calls for shared decision-making, interdisciplinary collaboration, and advance care planning to align treatment with patient goals and family capacity. It includes perspectives from clinicians experienced in treating ARP and offers practical recommendations for teams working across clinical settings.

Key Questions Answered:
A: Alzheimer’s-related psychosis changes a person’s behavior and safety profile in ways that memory loss alone does not. Hallucinations and delusions can provoke intense fear, confusion, or agitation, increasing the risk of falls, accidents, and confrontations. This heightened distress often accelerates decline and can force families into earlier institutional care than would otherwise be necessary.
A: Because there are currently no medications approved specifically for ARP, clinicians sometimes use antipsychotics off-label when a person poses a clear safety risk or suffers from persistent, severe psychotic symptoms. In those rare situations, clinicians weigh the immediate dangers of untreated psychosis against the medication risks and use the lowest effective dose for the shortest possible duration, with close monitoring.
A: Effective de-escalation emphasizes validation of emotion rather than factual correction. Caregivers are taught to acknowledge feelings (“I can see this is frightening”), offer calm reassurance, and use gentle redirection—physically and through environmental changes such as improving lighting or reducing background noise—to lessen sensory triggers that may be fueling the hallucination.
