Neuropsychiatric Symptoms Associated with Alzheimer’s Toolkit

As frontline providers, PAs practice in every medical setting and specialty, and are likely to treat patients with dementia experiencing neuropsychiatric symptoms (NPS). As the number of patients living with dementia increases, the resources in this toolkit are available to help PAs recognize, diagnose, and treat patients exhibiting NPS.

Demographics of Alzheimer’s Disease in the United States

~6.9million

Americans who are aged >65 years are living with Alzheimer’s disease (AD) in the U.S. in 20241

  • This is about 1 in 9 people
  • 73% of people living with AD are age 75 years or older
  • Almost 2/3 of people with AD are women
  • ~50% of Medicare beneficiaries are not informed they have been diagnosed with AD
  • AD more common in Non-Hispanic Black and Hispanic older adults vs. White adults
  • Underdiagnosis is more common among Black and Hispanic older adults
Up to 98%

of people with dementia experience neuropsychiatric symptoms (NPS)2

Core Neuropsychiatric Symptoms (NPS), which are also known as Behavioral and Psychological Symptoms of Dementia (BPSD) include:

  • Apathy, agitation, aggression, depression/anxiety, sleep disorders, psychosis (hallucinations and/or delusions)
  • Additional NPS include appetite/eating issue, motor disturbance, and disinhibition
  • NPS can be the 1st symptoms of AD, preceding cognitive/memory impairments

General Risks and Consequences of NPS

Increased morbidity
Increased mortality risk
Greater carepartner stress and burnout
Earlier need for long-term care placement

FAQs on Neuropsychiatric Symptoms (NPS)

What are Neuropsychiatric Symptoms (NPS) of Alzheimer’s Disease/Dementia?
  • Neuropsychiatric Symptoms (AKA Behavioral and Psychological Symptoms of Dementia [BPSD]) include apathy, agitation/aggression, anxiety, depression, and psychotic symptoms (delusions/hallucinations).
  • Also included are sleep disorders, eating problems, and disinhibition gait/motor disturbances (pacing, wandering).
How common are NPS in patients with AD?

Up to 98% of patients with Alzheimer’s Disease (AD) eventually exhibit at least one NPS.

When do they appear?

Some NPS can occur during mild cognitive impairment (MCI); they can precede the cognitive and memory impairments characteristic of AD; or they can appear anytime throughout the course of the disease.

What are the diagnostic criteria for NPS in AD?

ISTAART criteria (2017): “a substantial, clear change from patient’s typical behavior or personality in domains of apathy, affective dysregulation, difficulties with impulse control, social inappropriateness, abnormal perception, and thought of content for >6 months.”

How do you screen for and/or diagnose NPS?
  • Use available screening tools for specific symptoms, or simplify by identifying ~3 key questions and integrating them into routine office visits.
  • Follow up or refer positive screens to a specialist for more comprehensive evaluation.
What are the consequences and risks of NPS?
  • Increased morbidity
  • Increased risk of mortality
  • Increased need for early long-term placements (e.g. nursing home, memory care unit)
  • Faster care partner burnout
  • Increased risk hospitalization
Can you manage NPS via nonpharmacologic interventions?
  • All guidelines recommend using nonpharmacologic interventions first before medications.
  • Specific interventions depend on the NPS and can include:
    • Developing and maintaining routines
    • Distraction and de-escalation techniques
    • Maintaining hydration and appropriate nutrition
    • Developing good sleep hygiene
  • Learn more in the Nonpharmacologic Interventions for NPS article.
Can NPS be treated with medications?

Many medications used to treat anxiety, depression, agitation and sleep disorders are not indicated (and some even carry black box warnings) for use in this population because of the risks. Nevertheless, many drugs are used off-label under close monitoring.

Learn more in the Pharmacologic Approaches in the Management of Neuropsychiatric Symptoms in Alzheimer’s Disease (AD) article.

How is agitation/aggression managed in the emergency department?
  • Nonpharmacologic interventions are recommended as first-line treatments.
  • Minimize as many triggering factors as possible.
  • Use oral (vs IM or IV) second-generation antipsychotic medications if necessary.
  • Learn more in the Agitation in the ED and Urgent Care Setting article.
Can patients with AD and NPS drive?
  • Patients with early-stage AD likely can continue driving, but as the disease progresses driving capabilities should be evaluated by the DMV.
  • Clinicians should be aware of their state’s laws regarding requirements for reporting a patient’s diagnosis of AD to the DMV.
  • Learn more in the Alzheimer’s Disease and Driving article.
What is the optimal way to provide continuity of care between primary and specialty care clinicians?
  • Patients often are diagnosed in primary care settings, referred to specialty care as needed, and returned to primary care providers for continued ongoing care.
  • Arrangements are needed to provide access to patient records between the various providers.
  • Shared visits may ease the transition between providers, whenever possible.
  • Telehealth visits may also be an option when available.

NPS Screening Tools

  • Agitation in Alzheimer’s Screener for Caregivers (AASC)
    This structured assessment tool developed by Otsuka helps care partners identify behaviors and feelings associated with agitation in individuals they care for and can discuss with their provider.
  • The Neuropsychiatric Inventory Questionnaire
    (NPI-Q) The NPI-Q is designed to be a self-administered questionnaire completed by informants about patients for whom they care. Each of the 12 NPI-Q domains contains a survey question that reflects cardinal symptoms of that domain. The NPI-Q provides symptom Severity and Distress ratings for each symptom reported, and total Severity and Distress scores reflecting the sum of individual domain scores. Most informants will be able to complete the NPI-Q in 5 minutes or less.
