Dementia-related Psychosis Market and Epidemiology Analysis

• DRP reported more than 5 million diagnosed prevalent cases in the 7MM in 2025. In the US, more than 2 million cases were reported, of which Alzheimer’s disease Dementia reported the maximum number of cases.
• Diagnosis is primarily clinical and relies on structured assessment tools such as the Neuropsychiatric Inventory (NPI) and Brief Psychiatric Rating Scale (BPRS), along with caregiver-reported observations to evaluate the presence, frequency, and severity of hallucinations and delusions and their impact on daily functioning.
• Despite its high clinical burden, DRP management remains constrained by a continued reliance on off-label antipsychotics, antidepressants, and sedatives, underscoring a critical lack of therapies specifically approved for this indication. While pimavanserin (NUPLAZID) is approved for hallucinations and delusions associated with Parkinson’s Disease Psychosis, it was unable to secure approval for broader dementia-related psychosis; nevertheless, it continues to be used off-label in DRP settings, reflecting the limited availability of targeted and approved treatment options.
• The emerging Dementia-related Psychosis Pipeline is diverse and mechanism-driven, including Remlifanserin (ACP-204), COBENFY (KarXT), Zervimesine (CT1812), ML-007C-MA, among others, reflecting increasing focus on serotonergic, cholinergic, synaptic, and neuromodulatory pathways that may drive future advancements in the management of DRP.
• A significant Dementia-related Psychosis Unmet Need is the absence of therapies specifically approved for this indication; the only available agent is approved for psychosis in Parkinson’s disease dementia rather than DRP broadly. Moreover, the clinical pipeline remains limited and largely focused on individual subtypes such as psychosis in Alzheimer’s disease, dementia with Lewy bodies and Parkinson’s disease, with no therapies being directly developed for DRP as a unified condition, thereby restricting comprehensive treatment advancement.

Dementia-related Psychosis Market Size and Forecast

Key Factors Driving the Growth of Dementia-related Psychosis Market

• Rising Prevalence of Dementia across Aging Populations

One of the primary drivers of the dementia-related psychosis market is the growing global burden of dementia, particularly among the elderly. As life expectancy increases worldwide, the incidence of neurodegenerative disorders such as Alzheimer's disease, Lewy body dementia, vascular dementia, and Parkinson's disease dementia continues to rise. A significant proportion of these patients develop psychotic symptoms, including hallucinations and delusions, creating a substantial unmet clinical need for effective therapies.

• Increasing Awareness and Improved Diagnosis

Healthcare providers and caregivers are becoming more aware of the neuropsychiatric complications associated with dementia. Improved screening tools, standardized diagnostic criteria, and greater education among clinicians have enhanced the identification of dementia-related psychosis (DRP). Earlier diagnosis allows for timely intervention, increasing the number of patients eligible for pharmacological and supportive treatment.

• Growing Demand for Safe and Effective Therapies

Historically, treatment options for dementia-related psychosis have been limited, with off-label use of antipsychotics often associated with serious safety concerns, including increased mortality in elderly patients. The demand for therapies specifically developed and approved for DRP is driving research investments and market expansion. Novel treatments with improved efficacy and safety profiles are expected to transform patient management and fuel market growth.

• Advancements in Drug Development and Clinical Research

The dementia-related psychosis pipeline has expanded considerably in recent years, supported by advances in neuroscience, biomarker research, and a better understanding of disease mechanisms.

Dementia-related Psychosis Understanding

Dementia-related Psychosis Overview

Dementia is not merely about memory loss; it is a clinical syndrome where majority of patients experience Behavioral and Psychological Symptoms (BPSD). The most distressing of these is Dementia-related Psychosis, defined by hallucinations and delusions that persist for at least one month.

Clinical signs vary by subtype: Alzheimer’s often involves delusions of theft, while Lewy Body or Parkinson’s dementia is marked by vivid visual hallucinations. Beyond these, patients often face personality shifts, apathy, anxiety, and “sundowning” (worsening symptoms in the evening), all of which significantly increase the burden on caregivers.

Dementia-related Psychosis Diagnosis

Accurate diagnosis is crucial for delivering targeted interventions, such as appropriate antipsychotic medications, and for avoiding harm caused by misdiagnosis (e.g., treating pain-related agitation with antipsychotics instead of pain management). Current clinical criteria state that hallucinations and delusions must be present for at least 1-month to support a diagnosis of psychosis in dementia. Experts also agree that the duration and the severity of the symptoms should be addressed as separate clinical factors.

Current Dementia-related Psychosis Treatment Landscape

• Nonpharmacological interventions: They are the preferred first-line approach for managing psychotic symptoms because they address underlying triggers without medication side effects. Key strategies include improving the environment (better lighting, DRPep regulation, familiar surroundings, and correcting sensory impairments), using behavioral approaches (personalized activities and validation therapy to reduce distress), and enhancing sensory engagement (music therapy and familiar video recordings) to calm patients and reduce hallucinations and delusions.
• Pharmacological interventions: Pharmacological measures are considered second-line therapy, reserved for situations where non-pharmacological efforts are insufficient or when the patient’s behavior poses an immediate risk of harm. The emergence of NUPLAZID marks a significant milestone in DRP treatment, offering a specialized approach for patients with Parkinson’s, Alzheimer’s, and Lewy Body-related psychosis. By selectively targeting 5-HT2A receptors without blocking dopamine, it addresses the urgent need for a therapy that treats psychotic symptoms while preserving motor stability.

Dementia-related Psychosis Approved Therapies

• Pimavanserin (NUPLAZID): Acadia Pharmaceuticals

Pimavanserin (NUPLAZID) is an atypical antipsychotic indicated for the treatment of hallucinations and delusions associated with PDP. It is the first and only prescription medication approved by the US Food and Drug Administration (FDA) for the treatment of hallucinations and delusions associated with PDP.

The effect of pimavanserin could be mediated through a combination of inverse agonist and antagonist activity at serotonin 5-HT2A receptors and, to a lesser extent, at serotonin 5-HT2C receptors. It is used off-label in dementia-related psychosis as well to treat hallucinations and delusions.

• In April 2016, the US FDA approved NUPLAZID as the first drug approved for the treatment of hallucinations and delusions associated with PDP.

Dementia-related Psychosis Pipeline Analysis

• ACP-204 (Remlifanserin): Acadia Pharmaceuticals

ACP-204 (Remlifanserin) is a novel, highly selective 5-HT2A receptor inverse agonist being developed for the treatment of psychosis associated with Alzheimer’s disease. By selectively modulating serotonergic pathways implicated in neuropsychiatric symptomatology, the therapy aims to provide effective symptom control with an improved tolerability profile compared with traditional antipsychotics.

Acadia Pharmaceuticals has recently initiated a Phase III clinical trial to further evaluate the efficacy and safety of ACP-204 in this patient population, with a key clinical readout anticipated in mid-2026.

Dementia-related Psychosis Market Outlook

Current pharmacological management of DRP continues to rely heavily on off-label use of antipsychotic agents, primarily aimed at short-term behavioral stabilization and reduction of severe symptoms. While these agents may provide symptomatic relief, their use is constrained by modest efficacy, safety concerns, and limited durability of benefit, necessitating careful risk–benefit evaluation in clinical practice.

Typical antipsychotics, such as haloperidol, are sometimes used in DRP to manage hallucinations and delusions, particularly in acute settings. Overall, the current pharmacological paradigm for DRP remains largely centered on the use of antipsychotic therapies, often extending beyond their primary indications, to achieve control of hallucinations and delusions in a vulnerable patient population.
